1.4
Selection of the Cities
There are 3 categories of cities selected for financial support under the JNNURM.
Each category of cities has a specific financing pattern with variable grant funding
from the Government of India and the respective State Government. The categories
are as follows:

Cities/Urban Agglomerations with 4 million plus population as per 2001
census

Cities/Urban Agglomerations with 1 million plus but less that 4 million
population as per 2001 census

Selected Cities/Urban Agglomerations (these are state capitals and other
cities and urban agglomerations of religious, historic and tourist importance).

Jaipur, Ajmer and Pushkar (as one entity) have been included in Rajasthan
state under JNNURM.
As has been mentioned above, the focus area under the scheme includes all
infrastructure development. There are certain infrastructure sector like water supply
and sewerage, which needs immediate attention in the Town. In view of this the
augmentation of water supply & sewerage scheme of Ajmer and Pushkar towns has
been prepared under JNNURM scheme of Government of India.
1.5
Details About Both Cities
Although the cities of Ajmer and Pushkar have historically, politically and
geographically separate identities, with each city being founded on and thriving on
their unique characteristics, there are a number of commonalities which can be seen
to have driven the choice of Ajmer and Pushkar as a “single urban entity” under the
JNNURM.

1.5.1.4
Historical Background
Historical Background
Ajmer was founded by Ajaipal Chauhan, in 7th century. Ajmer derives its name from
‘Ajaya Meru’ the invincible hill, at the foot of which the present city stands. Here he
built India’s first hill fort Taragah. Ajmer was a Chauhan stronghold till 1194. The only
remains of their times are the fort and the beautiful Anasagar lake built in 1150 by
Anaji.
It was during the regime of Prithviraj Chauhan, in 1194, that Muhammad of Ghori
invaded India. Ajmer remained under the Sultanate till 1326. Thereafter, it became a
bone of contention between the Sultans of Delhi, the Ranas of Mewar, the Rathores
of Marwar and the Sultans of Gujarat. Peace was restored with the accession of
Akbar to the Mughal throne in 1556. He made Ajmer a full fledged province and the
base for his operations in Rajputana. He fortified the city, but only parts of the 4045yard (3735-m) long wall remain.
In 1659 a battle was fought in Ajmer between the Mughal princes, Aurangzeb and
Dara Sukoh, during which Taragarh was greatly damaged. In the first half of the 18th
century,Ajmer was affected by the political chaos in Delhi and the Scindia rulers of
Gwalior took over Ajmer. In 1755, the situation became more complex with the
involvement of the Marathas. In1818, finally the Marathas ceded Ajmer to Sir David
Ochterlony and, as part of the British Empire, it remained under the care of
successive superintendents.
During British rule, the city became the military headquarters of the British
government. Post independence, with the reorganization of the princely states Ajmer
became a part of Rajasthan.

AJMER’S MYTHOLOGY
Ajmer has been, for time immemorial, a great centre of pilgrimage, for both Hindus
and Muslims, a feature that gives the city its character. The city is a genuine
amalgam of rich Hindu and Islamic heritage. The sacred lake of Pushkar believed by
Hindus, to be as old as the temple of Brahma, has been a place of pilgrimage, for
ages. The great Sufi saint Khwaja Moin-ud-din-Chisti of Persia, was buried here, and
his Dargah is equally sacred for the followers of Islam, as well as Hinduism.
The picturesque setting of this city, surrounded by Aravali hills offers a distinctive
character to the city.
Key Tourist Sights
The Dargah
The Dargah is the tomb of a sufi saint, Khwaja
Muin-uddin Chisti, who came to Ajmer from Persia
in 1192. Construction of the shrine was completed
by Humayun. Constructed of white marble, it has
11 arches and a Persian inscription running the full
length of the building. It has a marble dome and
the actual tomb inside is surrounded by a silver
platform. The tomb attracts hundreds of thousands
of pilgrims every year on the saint's death
anniversary.

Adhai-Din-Ka Jhonpara
One of the finest examples of Indo-Islamic
architecture, this mosque was a Sanskrit
college in the 12th century. In 1193 AD
Mohammad Ghori destroyed the college
and hurriedly put together, a mosque
within two and a half days (Adhai Din)
with the remains of several neighbouring
temples. The mosque was built on pillars
and surprisingly no two pillars are alike.
Akbar’s Fort
It is the most important Mughal building from the historical perspective. Akbar
improved and extended the fortification of the city and made Ajmer his headquarters
for the operations in Rajputana and Gujarat. He visited Ajmer frequently to attend to
political matters as well as to pay homage at the sacred shrine of Garib Nawaz.
Sir Thomas Roe presented his credentials to Jahangir here on January 10, 1616.
The British occupied this palace in 1818 and it was extensively fortified during the
1857 uprising. Later it was used as the Rajputana Arsenal” and earned the popular
name Magazine.
The Royal Palace of Akbar was converted into a Museum and today it houses a rich
collection of Mughal and Rajput armoury. Some of the fine and delicate sculptures of
the region have been displayed here. The building itself has been constructed of red
sandstone which have been laid down in a square pattern, giving it a fabulous look.

Nasiyan (Jain Temple)
The Red temple near Mahaveer Circle is a Jain temple built in the 19th century. The
temple complex contains the Svarna Nagari Hall which is a double storey hall
containing a fascinating series of large, gilt wooden figures from Jain mythology
depicting the Jain concept of the ancient world. The hall is richly painted and
decorated; the roof is covered with excellent glass mosaic. It has illustrative
representations of the birth and life of Rishabhadev.
Ana Sagar Lake
This lake was built by Anaji during 11351150 AD. Later the Mughal emperors made
additional constructions to beautify the lake.
The 'Baradari', a marble pavilion was built
by Shah Jahan and the ' Daulat Bagh '
gardens were laid by Jahangir. This lake is
located towards the north of Ajmer city.

Taragarh Fort
Built in the 7th century by Ajaipal Chauhan, the fort gives birds eye view of the city.
When viewed from the valley down below at night the fortress on the crest of the hill
looks like a star adorned. Taragarh fort or the ' Star fort ' is situated on a hill is nearly
2-3 km in circumference on top of the hill. The fort has some important gates which
make access to the fort very difficult.
The first entrance to the fort is known as Lakshmi Pol or gate of wealth; the second
one is named by locals as Phuta Darwaza or broken gate; the third is the Gaudi Ki
Phatak and the last one is called the Gate of Victory. This is the principal entrance to
Taragarh fort. These gates make the fort inaccessible to invaders.
Taragarh is also important for a mosque and the shrine of Miran Sayyad Hussain,
governor of the fort, who died in 1202. Sanctity was attached to this shrine only after
Akbars; visit four and half centuries later.
Presently around 200 families live inside the fort. The reminiscence of the fort wall
reflects the history of the once important fort of the region, which was destroyed by
Mohammad Ghori.
Shah Jahan's Mosque
This mosque is the most beautiful of all the structures, in the Dargah precinct. It is
made of white marble, delicately carved with trellis-work.

centres in the city. Ajmer is also a large market for metal scrap – thus resulting in a
number of small scale industries such as foundries & iron works. RIICO has
developed two industrial estates (small scale industries) at Parbatpura and
Makhupura. There are 165 industrial units providing employment to around 6500
individuals, one third of which is engaged in bidi manufacture.
There are also a large number of poultry farms in and around Ajmer. The moderate
climate of Ajmer is conducive to poultry farming and it supply poultry products to the
other cities in the state.

With presence of Dargah in the city and proximity to Pushkar, tourism is also a key
economic driver. Tourism related services provide employment to a considerable
percentage of the population in the formal and informal sector - hotels, restaurants,
tour operators, transport operators, retail trade.
Ajmer also acts as a wholesale commercial centre for the surrounding towns and
villages.

1.5.2 PUSHKAR:
1.5.2.1
Pushkar ……. An Introduction
Pushkar is one of the major pilgrimage centres in India with over 500 odd temples in
and around the city. The most sacred being the Brahma Temple. This holy town is
situated around the sacred Pushkar Lake/ Sarovar in the valley formed between two
parallel hills of Aravali mountain ranges running south-west to north-east. The height
of the hills range between 650m to 856m.
Pushkar is situated 12km north west of Ajmer. It is located at latitude 260 27’ North
and longitude 740 37’East, at an elevation of 530m above mean sea level. Pushkar
lies on the eastern fringe of the Thar desert.

1.5.2.2
Connectivity
The town is approached by road only. The nearest rail head is Ajmer. The town is
linked to other pilgrim centres such as Mathura and Ujjain, via Ajmer. State Highway
18 connects Pushkar to Ajmer. The same road links Pushkar to Merta (70km) and
Nagaur (150km).
1.5.2.3
Climate
The climate of the town is semi-arid with dry and hot summer and cool winter. The
hottest months are May and June with maximum temperature of around 45 0C, while
in winter the maximum mean temperature is 25 – 10 0C. During the months of April
to September strong winds prevail resulting in the formation of sand dunes. The
prevailing wind direction is southwest to north-east. The monsoon season is
relatively short from July to August with average rainfall ranging from 400 to 600mm.
Occasionally rainfall is received during January and February.
1.5.2.4
Historical Background
The origins of Pushkar are unknown. However it is amongst the oldest pilgrimage
centres in India. The inscriptions found at Sanchi attest to its existence in late 2nd
century BC. The discovery of punched coins as well as Greek and Kushan coins
push back the existence of Pushkar to the 4th century B.C. What makes the
discovery of these coins is that Pushkar is nowhere near a trade route. This suggests
that travellers came here explicitly on pilgrimage.
Apart from a few silver coins of the Gupta period there is not much information of that
era. During the invasions of Huns, Pushkar was razed to the ground, and forgotten till
the beginning of 9th Century AD.
-14-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
In the 12th century under the Chauhan rule there took place a renaissance in
Pushkar. The Chauhan kings extended their patronage to this holy place. A number
of religious buildings were commissioned during this time.
With the beginning of Mughal rule in India Pushkar’s fortunes were eclipsed. There
was no new construction or renovation. Religious processions were banned and
pilgrim tax was imposed.
With the formation of the Rajput coalition under the leadership of Mewar Pushkar
once again flourished. So did its neighbour Ajmer under the patronage of Akbar who
became a staunch believer of Mouinuddin Chisti’s Dargah. The pilgrimage tax was
revoked.
For Rajput leaders visits to Pushkar and subsequent donations were not only
religiously motivated; such acts also enhanced their status. Pushkar received special
attention from courts of Amber, Bundi, Bikaner and Jaisalmer. Maharaja Man Singh
of Amber had the Raj Ghat and Man temple constructed at Pushkar, while Rana
Pratap had the Varah temple renovated.
The Marathas also sponsored a number of structures at Pushkar. The Kot Tirth Ghat
constructed by Daulat Rao Scindia. In 1757 Anaji Scindia had the Koteshwar
Mahadev temple constructed. In 1760 Shiva Ghat was renovated by Govind Rao the
Maratha governor of Ajmer.
Under the British rule too patronage at Pushkar continued. Rich businessmen who
settled in Ajmer donated generously towards construction of religious buildings.
Over the years the annual commemoration of Brahma’s Yagna on Kartik Purnima
developed from a solely religious event to an informal market place where people
bought and sold various agricultural products and cattle. The British organised it into
a regular cattle fair. Taxes on the sales were used to develop other facilities.
-15-

Post Independence the royal families gave up much of their holdings in Pushkar. In
1956 the Maharaja of Jaipur handed over the Jaipur Ghat as well as the Man Palace
to the government. This was later converted into the Tourist Bunglow.
1.5.2.5
PUSHKAR’S MYTHOLOGY
As per Hindu mythology, the lake was created by the falling of a lotus from Lord
Brahma’s hand. The name ‘Pushkar’ is derived from the word “Pushp” meaning
flower and “Kar” meaning hand. According to Padam Purana, Lord Brahma was in
search of a suitable place for a vedic yagna (sacrifice). While contemplating, a lotus
fell from his hand on the earth and water spurted from three places. One of them was
Pushkar and Brahma decided to perform his yagna there.
After the Yagna was performed by Brahma, Pushkar became a holy place. A dip in
the holy Sarovar is believed to absolve man of all his sins.
Key Tourist Sights
Temples
There are as many as 80 temples open for public besides hundreds of small temples
situated in the private houses throughout the town.

Brahma Temple
The most famous temple in Pushkar, is the only temple dedicated to Lord Brahma
(the creator of the universe according to Hindu mythology) in the entire country. Its
key features are the red spire and the image of a hans (the goose considered sacred
to Lord Brahma).This temple built with marble is decorated with silver coins and there
is a silver turtle on the floor of the temple. The marble statue of Lord Brahma sitting
in Padmasan in Lotus with Gayatri, was installed by Adishankaracharya in 718A.D.
Varah Temple
The Varah temple houses an image of lord Vishnu in the incarnation of wild boar.
Mythologically a very important temple and is believed that Lord Vishnu came to
earth in the incarnation of Warah (wild boar) to kill the demon Hirnayaksh and
liberate the land from his atrocities. This ancient temple built by King Anaji Chauhan
in the 12th century was demolished by Aurangzeb but reconstructed by Jai Singh II
and the present image was installed in 1729.
The temples of Brahma and Warah are considered equally important.
Old Rangji Temple
The gracious temple is very conspicuous, due to its south Indian style of architecture.
It has a high rising 'Gopuram' typical of southern India. It was constructed in 1901 by
Seth Puranmal of Hyderabad. Here the priests are Dravidian Brahmin and south
Indian festivals and rites are followed.
New Rangji Temple
This temple is also known as Baikunth Mandir, was constructed between 1920-1925
by a Maheshwari seth at the cost of Rs.8 lakh. Its architectural style is south Indian
and here too southern rites and rituals of ramanuja Viashnava sect are performed by
south Indian priests.

Apteshwar Temple
Another important temple of the town, this 12th century temple is dedicated to Lord
Shiva.
Savitri Temple
The temple of savitri is built on the south-west of the lake on Savitri Pahar by the
Purohit Ajit Singh of Marwar.
Others
Raghunath Temple, Lakshminarayan Mandir, Behariji Temple, Teoram Temple,
Kapileshwar Temple, Jain Temple etc.
In addition to the temples Pushkar has many Ashrams imparting meditation and
religious teachings as well as temporary abode to people desirous of salvation and
peace.
Lake and the Ghats
The most important part of the town is the Sarovar or the holy lake. The lake is
surrounded by Aravali hill ranges forming a catchment area of 22sq.km. It is a
stagnant water body formed by the collection of rain water from the catchment area
in a natural depression and is replenished mainly by the monsoons in the month of
July-August. Although the lake is perennial, its depth varies considerably between
rainy season and summer season. The lake covers an area of 22Ha with a capacity
of 0.79 million cubic meter and its depth varies from 8 to 10m.
The Sarovar is encircled by Ghats, 52 in number, except at its southern edge where
rain water from its catchment area flows in through a series of arches below a 110m
long foot bridge, which completes the girdle around the lake and facilitates the
-18-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
pilgrims’ Parikrama around it. Some of the ghats are believed to be hundreds of
years old but the structures are maximum 400 years old.
Among the important ones are Brahma Ghat, Gau Ghat, Varah Ghat, which are the
oldest ghats. The important elements of the Ghats are bathing steps, temples,
dharamshalas, Purohit house, Chhatries and small cubicles (changing rooms).
The total area under the Ghats is 2Ha.
Other places of tourist interest
Sunset Point – Located at the Jaipur Ghat this spot is a major tourist attraction
during sunset as it presents a beautiful view of the skyline of the town and ghats in
the western part of the lake. Here the colour of water changes with the colour of sky.
Jahangir’s palace – This monument is located south of the lake along the
Parikrama path. It was built by Jahangir in 1670 AD to celebrate his victory over
Maharaja Amar Singh of Mewar. It is a protected monument.
View point – Savitri temple: This point on the Savitri hill offers a magnificent view of
the town, the surrounding hills and the sand dunes. The Savitri temple is also an
important place of pilgrimage.
Markandeya cave: It is an ancient cave situated in the Nag Pahar just above the
origin of Saraswati river. This place is supposed to be abode of Saint Markandeya.
Pap Mochini Temple: This temple is located on the Dungar Pahar, northern side of
the town. A fair is held here in the month of September.
Augustya Muni Cave: It is a cave on Nag hills, 2 km from Budha Pushkar. Augastya
Muni is believed to have meditated here.

1.5.2.6
Trade and Commerce
Tourism is the main economic driver of the town, which promotes other key sectors
such as trade and commerce, transportation and household industries. Like any
other pilgrimage town, even in Pushkar has around 300 odd temples majority, of
Brahmins are engaged in religion based economic source, which is their traditional
occupation. However due to increase in foreign tourists many young Brahmins have
set up their own businesses. The trade and commerce is related to temple needs
and caters to pilgrims and tourists. There are no wholesale activities in town. There
are 95 hotels and rest houses and 24 restaurants /cafeteria. The tourism in Pushkar
provides livelihood to a large section of the population.
The cattle fair is the main economic activity in the region. Most of the local people
make 80% of the annual income during the Pushkar Fair.
Garment manufacture is the only significant Industrial activity which employs around
5000 persons, most of these workers come nearby villages. The household
industries include – traditional handicrafts and production of rose by-products eg.
Gulkand, rose oil, rose water etc.

1.5.3 Geographical Proximity
Both cities are located in Ajmer District separated by a distance of around 22 km.
This close geographical proximity has implications on developing common transport
linkages as well as movement of sections of the population between the cities and
common economic activities.
1.5.3.1 Geophysical Similarities – both cities are located in a semi-arid region of
the state bounded by hills in the Aravalli range, with the visible presence of
ecological pressures on water bodies and green cover.
1.5.3.1 Historical and Religious Antecedents – both cities are old by any
chronological standard and have a rich historical past. Ajmer was founded in the
early 7 th Century by Ajaipal Chauhan and has witnessed a succession of rulers
(including the Mughals and the Marathas), with the British finally taking over the city
in 1818. The importance of Ajmer as a religious centre came about with presence of
Hazrat Khwaja Moinuddin Chishti, who spent his last years in the city. The genesis of
Pushkar is interwoven with Hindu mythology and it forms one of the five places of
pilgrimage held in high esteem by Hindus. A visible imprint of this rich historical and
religious significance of both cities is the presence of a large number of historical
monuments and places of religious importance and the large number of tourists
visiting both cities.
1.5.3.1 Infrastructure Needs – both cities have mutual dependencies and
similarities when it comes to basic infrastructure such as water supply, sewerage and
sanitation, housing and environment protection. The tourist potential of both cities
also leads to the need to explore the role of common tourism infrastructure wherever
possible.
In addition to the above, the investment needs of both the cities if considered as a
single entity is likely to be more amenable to leveraging funds from multiple sources
and managed and executed by a common institutional mechanism. However, each
-21-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
city also has its unique needs. Therefore, although for the purposes of the Mission,
the cities are being treated as a “single urban entity”, this water supply proposal is
prepared as one because of common source of water supply from Bisalpur Dam, a
place 115 km from Ajmer on Banas River.
-22-

2.1
Need of the Project
This project of water supply to Ajmer and Pushkar towns mainly relates to
improvement in transfer and distribution networks of both the cities. The last
major augmentation in Ajmer water supply was sanctioned from Bisalpur Dam
in the year 1987 for the water demand up to year 2002. This project known as
‘Bisalpur Phase-I’ was completed and commissioned in 1995, has been
sufficient, to meet the water demand up to the year 2006. Currently a water
supply project for transmission main pipeline from Bisalpur Dam to Ajmer city
known as ‘Bisalpur Phase-II Project’, to meet the water demand up to the
year 2021, has been sanctioned in the year 2006 and is currently under
execution. This project also includes the water demand of Pushkar town. The
horizon year of 2021 has been taken because of water reservation in Bisalpur
Dam storage reservoir up to year 2021 only. There after the storage capacity
of Dam shall need augmentation from nearby perennial river or storage Dam.
This transmission main pipe line under Bisalpur Phase-II project shall be
capable to draw the balance quantity of water reserved for Ajmer District in
Bisalpur Dam.
2.2
Pushkar town presently is getting water from tube wells/open wells located
around Pushkar. Due to continuous drought and over exploitation of ground
water by farmers, the yield of tube wells has considerably reduced so much
so that the entire block around Pushkar town has become critical and
unsuitable for drilling of new tube wells. It has therefore become necessary to
bring Bisalpur Dam water to Pushkar town so as to meet the water demand of
equally important pilgrimage city. The transmission main pipeline of Phase-II
project currently under execution includes the water demand of Pushkar town
up to the year 2021.
2.3
The sanctioned project Phase-II provides for delivery of 136 (135.86) MLD of
water at SR7 Makhupura storage reservoir. This SR7 is located on a hill
sufficiently high so as to supply water to a major part of Ajmer city by gravity.
Ajmer is surrounded by hills and a significant part of population resides on
-23-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
hills for which re-pumping of water at 5-6 pumping stations is required to be
done. In the earlier times, when first scheme from Banas river was
commissioned in 1968 water was supplied to the city under gravity from SR7
at Makhupura with only about 25% of water being re-pumped at PS8
Daulatbagh and PS9 Kesarganj pump stations.
2.4
Due to increase of population and expansion of towns in all directions
including higher elevations of hills, the quantity of water needing re-pumping
increased considerably. More over Ajmer city water supply always suffered
from the problem of low production of water, therefore, not enough attention
was paid to transfer and distribution systems in a holistic manner. The
problem of inadequate transfer system further increased and got complicated
due to over aged and overused, unhealthy condition of old 750mm dia M. S.
transfer pipe line, commissioned in 1968 at the time of first Banas scheme so
much so that even 800/700mm P.S.C.C. pipe line laid and commissioned
under Bisalpur Phase-I in 1996 could not improve water supply pressures in
city. Presently about 50-55 MLD water is taken through 800/700mm P.S.C.C.
pipe line and only about 10-15 MLD water through old 750mm M. S. pipe line
resulting in low pressures in city.
2.5
With the sanction of Phase-II of Bisalpur project for transmission main
conveying about 136 MLD water at SR7 at Makhupura the availability of
water is fully assured. This available water now needs to be properly
distributed in the city and as far as possible under gravity and without repumping so as to save on maintenance expenditure. For a proper distribution
system, a holistic view of entire city distribution along with transfer main pipe
lines to Ajmer city and Pushkar and expanding and future developing areas of
both the towns, is required to be taken. With this aim in view, this project has
been framed to obtain financial assistance for execution of project under
JNNURM.
2.6
In addition to above, the following reasons also necessitate the early sanction
of this project for improvement in transfer and distribution system of water
supply of Ajmer and Pushkar towns
-24-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
1. The city of Ajmer has grown both in population and area over the years,
especially the city boundaries have extended substantially after the
commissioning of Bisalpur Phase-I project which promised of a reliable and
assured source of water supply to Ajmer.
2. Due to growth of business and changing lifestyle, the expectations and
consumption of water has gone up over the years.
3. The present supply intervals in Ajmer are 48 to 72 hours, which need to be
reduced by augmenting the system.
4. The distribution and storage system in the city also needs augmentation so
as to match the needs of the city which has undergone substantial horizontal
expansion.
2.7
Moreover Ajmer and Pushkar cities are at the tail end of water supply system,
115km away from source (Bisalpur Dam) up to SR7 Makhupura and further 6
km for Ajmer and 37 km for Pushkar town without having any break down
period or maintenance period storage reservoir, which is a very big
deficiency of system. The size of transmission and transfer pipe lines are
1700 to 1000 mm which take atleast more than 24 hours in de-watering and
re-charging and a minimum of 24 hours are required for repair to any
defect/breakdown or regular maintenance. Hence 3 days storage is required
in such tail end user cities for reliable daily supply. Assuming one day storage
is available in cities, the net storage to be created in Ajmer and Pushkar shall
be two day’s daily demand. This project also provides for creation of such
storage capacity in both the cities.
In view of the above submissions, this project has been prepared to address
to the problems of inadequate storage, transfer and distribution system of
Ajmer and transmission and distribution system of Pushkar town.

Demographic Details
3.1
AJMER
Population of Ajmer city in 1941 year was 1,47,758, which is increasing in
every decade. The growth rate during 1941-51 was 33.08% due to influx of
migrants from Pakistan after partition of country in 1947. During 1971-81, the
growth rate was 41.85%. This higher rate was due to the fact that in the
census year 1981, the villages contiguous to urban area were included in new
urban limits of 1981 census. Later on during census of 1991, many villages
were excluded from the municipal limits of Ajmer, thus the growth of
population in 1981-91 was only 7.22% as compared to 14.51% in 1961-71 and
41.85% in 1971-81. Again the population growth rate increased during 19912001, which was 20.58%. The table below shows the population of Ajmer
since 1941-2001.

Projection of future population
3.1.1.1.A critical factor in estimating the requirement of urban infrastructure for future
planning, design and investment outlay is the projection of population. The
basis of projection is based on the following factors:

Past census population of the city;
-26-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM

Decadal growth and growth rates of the country, state and the city;

Population density pattern and availability of land for the future growth of
the city;

Socio-economic
characteristics
and
economic
base
along
with
employment generating potentials of the city;

Relative developmental characteristics of similar project areas;

Development (Master) Plan for the city considering the contextual issues
stated and growth pattern of the city in terms of land-use and land
availability for growth including proposed plans and potential for significant
change in land-use (within project period/ design life);

Positioning of the city in terms of its hinterland, linkages and connectivity
and importance as an economic base for the region;

Availability of resources to facilitate provision and delivery of services and
facilities;

Implications of the on-going and proposed projects towards improving the
provision and delivery of services;

Other external and internal growth dynamics responsible for migration; and

Other factors - tourism, natural disasters and related.
The impact of the above factors was considered while assuming the growth
rate for population projection. Future population projection is carried out based
on the following methods which are generally acceptable for urban planning
and development related planning.
1. Arithmetic Increase Method
2. Incremental Increase Method
3. Geometrical Increase Method
The base criteria adopted for the projection of future population are listed
below:

Year of study-2007

Census Years-2001, 2011, 2021, 2031, 2041

Design Stages-2009, 2016, 2021, 2024, 2031, 2039
As per CPHEEO guidelines and general construction practices, civil
works/structures are designed for a nominal service life of 30 years and
-27-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
mechanical/electrical equipment for 15 years. Therefore, design stages
essentially reflect the period/duration for which projection is required to design
the replacements, renewals and reconstruction activities. Projection of future
population has been performed for the years 2039 & 2041.
3.1.1.2.METHODOLOGY AND EVALUATION
The methodology used to project growth of population in Ajmer is outlined
below:

A pilot projection was performed to evaluate the past trend of decadal
growth, i.e.

The population of 2001 was projected by utilizing available census data
from 1951 to 1991. The projected value (by numerical and graphical
methods) was then compared with actual census population to identify the
method that resulted in the minimum allowed variation;

Projection of future population (2001-2041) was then performed by utilizing
the method(s) that resulted in the minimum allowed variation. In cases
where the variation was found to be significant, then all methods were
utilized;

An additional projection method considering the present ward density in
2001 and the ward-level potential for development was also carried out
and

Finally, results from the aforementioned methods were compared, average
decadal growth rates computed and recommendations were provided
accordingly.

3.1.2.1
Ward wise population projection of Ajmer town
Ajmer town is divided in 55 municipal wards. The ward wise population by
area of ward and density of populated as per census year 2001 is given in
Table below. Out of 55 wards, ward nos. 15, 16, 17, 18, 19, 20, 21, 22 and 29,
30, 31, 32 are over saturated. Ward no 30 has highest density of 1179 person
per hectare. The 12 wards are very congested and no land is available for
future expansion. Buildings are also two to three storied and there is no
possibility of vertical expansion.
The ward no 10 located on the south of the city along Ajmer-Beawar road has
maximum area of 1179.28 hectare and lowest density of 11 persons per
hectare.
Population projection for each ward (except ward no 15 to 22 and 29 th 32)
has been done on the following assumptions
a. Availability of vacant land for residential use in each ward.
b. Potential for future development in each ward based on proximity to city
related infrastructure and transport facilities.
c. Present land use pattern and possible change in land use over the project
period (generally 40 years)
d. Possibility of vertical expansion in existing residential houses due to
demand of more houses and improved economic conditions of residents
and availability of financial help.
e. Construction of group housing projects in future with high density.
Based on the above assumption, the table at annexure -____ gives the ward
wise population and density for all the 55 wards.

Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
The population has shown a steady increase since 1901. Census figures of the preindependence period show a negative trend up to 1921. The decline in population
was a result of a chain of famines experienced throughout Rajasthan. The decade of
1941-51 registered a highly accelerated growth rate of ---------% essentially because
of massive influx of refuges from across the border. Figure below shows the
population growth for Ajmer.
3.1.3
Population Growth
The present population of Ajmer is estimated at around 16000 (in 2005, at the rate of
2% annual growth). Unlike other towns population of Pushkar in the last five decades
has grown very slowly from 5934 in 1951 to 14789 in 2001. This population growth of
the town is largely due to natural growth, as there isn’t any major economic activity to
boost migration.

lively cattle fair is held in Pushkar annually during the month of November, which
coincides with Kartik purnima celebrations. Around 4 lakh people and about 40000
animals gather here during the fair. Villagers from all over Rajasthan come to sell
their animals and handicraft goods at the mela.
The Mela is jointly organized by RTDC, Municipality, Animal Husbandry Department.
Animal Husbandry department organizes cattle exhibitions, provision of water and
fodder for animals at affordable rates. Medical facilities including inoculation of the
cattle are also provided by the Department of Veterinary hospital.
Illumination and beautification is done by municipality at various points in the town.
Temporary tented accommodation is created by RTDC at the tourist village to
accommodate around 1700 tourists.
Accommodation
The available accommodation is far short of supply. Some tourists have to stay back
in Ajmer because of lack of accommodation in Pushkar. At the tourist village the
accommodation for low spending group is approx. 3000 this forces the villagers to
sleep in the open in cold November nights.

History of Ajmer Water Supply
5.1 Ajmer district has eight major towns namely Ajmer, Kishangarh, Beawar,
Nasirabad, Kekri, Sarwar, Bijainagar and Pushkar. The Bijainagar town is
covered under fluoride project and connected to Bisalpur dam recently. While
Pushkar has its own source and Ganhera water is used for piped water supply
system. Remaining all the towns of the district are covered by piped water
supply schemes through Bisalpur Dam. All the schemes except for Nasirabad
are maintained by the Public Health Engineering Department of the state.
Water for Nasirabad town is supplied by the PHED in bulk quantities to the
Cantonment Board for civilians and to MES for the Military requirement.
5.2 In the existing water supply system of Ajmer, the major source of water supply
is Bisalpur dam. The average per day water production in the month of March
2001 is as under:
Bisalpur dam :
143.13 lac gallons (64.98 MLD) : 649.81 lac litres
Foysagar
:
0.59 lac gallons
: 2.68 lac litres
Bhaonta
:
1.29 lac gallons
: 5.86 lac litres
Ganhera
:
2.19 lac gallons
: 9.94 lac litres
Local wells
:
Nil.
5.3 FOYSAGAR LAKE:
Water supply for Ajmer town was started by Ajmer Municipality from Foysagar
lake in the year 1907 by gravity through a 300 mm dia CI pipeline up to
Chamer ghati tanks from where water used to be distributed in small part of
town near Delhi Gate. Catchment area of Foysagar Lake is 8.50 Sq. miles
(236.97 M. Sq. feets) and the capacity of the lake was 142 M.Cfts. (3.976 M.
Cum) In the year 1981-82 height of Foysagar dam was raised by 4' (sill level
by 1'9") to increase the storage capacity from 142 Mcft (3.976 M. Cum) to 165
mcft (4.62 M. Cum) to get regular supply of 10 lac gallons (45.4 lac litre) per
day. The source works to its full capacity in the years of good rainfall. At
present it is almost dry. The rapid gravity filter cum filter house with two filter
beds of size 20' x 10' was constructed in the year 1961 having capacity of 7.5
lac gallons/day (34.5 lac litre/day). Pre chlorination is done by adding
bleaching powder solution. The water received in the mansoon period in the
-41-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
lake is generally used in the days of URS fair and Pushkar fair to
accommodate the floating population to a certain extent. No such contribution
is available in the daily water supply system now a day.
5.4 BHAONTA WELL FIELD: Bhaonta well field was developed on Sagarmati
river in the year 1917. The water from wells and tube wells is collected in the
masonry CWR at Bhaonta having 40000 gallons capacity from where water
was pumped into Break pressure tank at Ajaysar and water from Ajaysar tank
it flows through 10" C.I. gravity pipeline to Chamer Ghati tanks. Originally high
head pumps (400') were operated by steam engines at Bhaonta headworks.
There after steam engine have been replaced by electric pumping sets. This
source used to provide about 6 lac gallons water per day.
The system was updated and extended from time to time and Bhaonta system
used to supply water to Ajmer through two routes, namely, Foysagar side and
Beawar Road side. Due to insufficient rainfall during the last decade, the well
field capacity decreased considerably and no such considerable production is
received. Therefore production from Bhaonta is considered as zero while
designing the second phase of Bisalpur project.
5.5 GANEHRA WELL FIELD: New well field of Ganehra was developed in the
year 1952. At present there are 15 open wells and 6 tube wells. During
augmentation of Ajmer water supply system 4 new tube wells were
constructed in the year 1992 near Leela Sevari village. Water from this system
used to reach Ajmer from the Pushkar Road side and this source served the
city for years together. Optimum capacity of 16 lac gallons/day has fallen to 23 lac gallons per day during the last decade. Due to the rapid depletion of
ground water table in Ganheia-Pushkar region and the protests by the local
population, this very important source is no more in use for supplying water to
Ajmer. Also, looking to the local sentiments and status of ground water, it is
likely that this source will serve only the local needs; hence, it is not
considered any more as a source for Ajmer city.
5.6 IST PHASE OF BANAS SYSTEM: It was sanctioned in 1962 and
commissioned in the year 1968 at a cost of Rs. 282 lacs. Under this scheme
40 tube wells on the bank of Banas river near village Negdia (South of Ajmer
along .Ajmer-Kota Road) were constructed. Water of these tube wells was
-42-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
collected into CWR of pumping station no. 1. Water collected into CWR of
pumping station no. 1 was further pumped by 5 pumping station namely P.S.
no. 2,3,4,5,6 through rising main in a length of 100 kms. And collected in
service reservoir no. 7 situated at Makhupura Ghati on Ajmer- Nasirabad road
capacity of this system was 3.80 MGD from service reservoir no. 7, water was
supplied to almost 40% area of the town situated on the both sides of AjmerNasirabad road and city area through P.S.No. 8 and 9, situated in Ajmer city.
The distribution system of Ajmer town was under the control of
Municipal council, Ajmer till June, 1974 and there after PHED took over.
These 40 tube wells constructed during the year 1965-67 went dry within a
period of 3-4 years after commissioning of this scheme. Subsequently some
wells namely Chatari well, Negadia well, Deoli well on the bank of Banas river
and some tube wells in the bed of Banas river at Chatri basin and near Deoli
open well were constructed to sustain the capacity of system. After taking over
the internal system of water supply of Ajmer town from Municipal council
Ajmer and due to less rainfall during that period & rapid growth of population
reflected increase in water demand, proposals for 2nd phase of Reorganization of Ajmer water supply scheme were framed and placed for
approval.
5.7 2nd PHASE OF BANAS SYSTEM: It was sanctioned in the year 1978 and
commissioned in the year 1983. Under this scheme, new well field at Chatri
and Sandla were developed. Infiltration gallary in a length of 250 meters with
one jack well and 6 infiltration wells was developed near village Deopura in
the bed of Banas river. The capacity of this system was increased by
additional 3.80 MGD and for that second parallel AC pressure pipeline of 500
mm size was laid from pumping station no. 2 to 6 with installation of more
pumping set at pumping station no. 1,2,3,4,5,6. Improvement works in
distribution system and storage in the city were also taken up. Even after
construction of additional tube wells, jack wells and infiltration wells, the
production reduced during the summer of 1985-86. Production from Jack wells
and infiltration wells reduce in the month of April- may as & when flows in river
reduced. To meet out shortfall in production from Jack well and infiltration well
to a tune of 20 lac gallon/day, the department had constructed additional 20
-43-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
nos. of tube wells in the year 1987 near village Sandla to bring 20 lac gallons
of water per day through newly laid additional parallel AC pressure pipe line of
400 mm size in 7.50 kms length up to PS no. 1 and from where water is
pumped onwards through existing system.
5.8 BISALPUR WATER SUPPLY SYSTEM- Phase-I: The capacity and
reservation of water for various sectors in the Bisalpur dam are as follows:

Capacity of Dam
: 893.91 M.Cum.

Reservation of drinking water for Ajmer,
: 458.46 M.Cum.
Beawar, Kishangarh, Jaipur and en-route villages.

For Irrigation
: 226.40 M.Cum

Seepage and evaporation
: 209.05 M.Cum.
The reservation of water for Ajmer district in Bisalpur dam is 141.26 M CuM
which is equivalent to 387 MLD for 365 days.
Due to scanty rainfall and poor hydrogeology of the area, yield from ground
water sources has been negligible. During the period 1984-94, there has been
acute water crisis in the area resulting in reduction in frequency of water
supply to the urban towns of Ajmer, Beawar and Kishangarh to as low as once
in 48 to 96 hours, for a duration of half to one hour only, in the various zones.
Looking to the unprecedented scarcity Bisalpur water supply project, for
augmenting water supply to Ajmer , Kishangarh , Beawar , Kekri , Nasirabad
and Sarwar towns, was sanctioned in the year 1987. The scheme envisaged
construction of a dam across the seasonal but nearest river Banas, near
village Bisalpur, approx. 120 Kms south of Ajmer. The water stored during the
mansoon season was purported to be used for the requirement of water for
the six urban towns of Ajmer district. The phase I of the Bisalpur Water supply
was prepared in 1987 and the administrative and financial sanction was
accorded to it by the PPC, RWSSMB, Jaipur in its 40th meeting held on
24.6.87 and it was technically cleared by the CPHEEO, Government of India,
New Delhi vide their letter- number q:12023:1:87 dated 12.8.87 for Rs.64.37
crores.
-44-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
The revised Phase - I project was accorded administrative and financial
sanctioned by the CPHEEO vide letter no. Q: 12026:1:87 dt. 21.1.93 for Rs.
153 crores. The project has been commissioned in the year 1995. This project
serves to augment the supply of these six towns by 132 MLD. The per capita
supply in the augmentation scheme has been taken as 150 Litres/day for
Ajmer town and 100 - 120 Litres/day in the remaining five towns. While
Pushkar town had adequate local sources of drinking water, in view of the
hydrology of the area, and under fluoride control project the water requirement
of Vijainagar town is met through Bisalpur Dam.

Water Supply Scheme Pushkar – Background and present status.
Water supply scheme of Pushkar was commissioned in year 1962 duly
sanctioned by the Superintending Engineer, PHED Rajasthan Jaipur vide no.
H/25/dt. 4.8.59 dt Rs. 4.97 lac only. The original scheme was designed to
cater to 10500 souls up to the year 1988 with source of 2 nos tube wells.
Further augmentation of scheme was carried out in the year 1991 costing Rs.
31.23 lac on the basis of 1981 census population which was 9363 with a
floating population of 2500 souls. Four nos of tube wells, OHSR near Tehsil of
capacity one lac gallons was constructed according to sanctioned package.
No separate augmentation of Pushkar scheme was required because the
shortfall in water production was usually met from the water produced from
Ganhera well fields, which was developed for supplying water for Ajmer town
as the rising main from Ganhera to Ajmer passed through Pushkar town and it
was easy to tap and take water from the rising main for use in Pushkar.
Presently when water production for Ajmer town has been stopped from
Ganhera well field, the requirement of water for Pushkar is being met out of
the production from wells located in Ganhera well field.
6.1
Present status of Water Supply:
The present production of water for Pushkar town from different sources is as
follows:Ganhera Well Field
:
1.2 MLD
Leela Sevari Tube wells
:
0.3 MLD
Tube wells for Pushkar town :
1.6 MLD
The distribution of water out of this production is as follows:Pushkar town
:
1.3 MLD
Ganhera village
:
0.3 MLD
Pushkar Sarover
:
1.5 MLD
The present service level of Pushkar town for population of above 15,000
(approx.) souls based on water production of tube wells around Leela Sevari
and Pushkar minus the water released in the Pushkar Sarover comes to about
(1.9-1.5=0.4 MLD/15000) 27 lpcd. In this per capita supply the water
-46-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
requirement of the floating population of roughly about 3000 souls is not
included. On account of over exploitation of ground water in the Pushkar area
it has been decided at the government level to close down the wells/ tube
wells around Ganhera well field but it has not been possible to completely
close down the pumping of water from well/ tube wells because of public
resistance. But in the long run the ground water source in Pushkar cannot be
relied upon as a source of water supply for this important pilgrimage town.
6.2
Existing Distribution System of Pushkar:
Presently Pushkar town has been divided in 3 zones for the purposes of
supplying water in the city. Water from the tube wells is collected in CWR at
Headworks Pushkar and pumped in to the OHSR located in zone no.2 and
GLSR on hill located in zone no-1. The water in zone no-3 is presently
supplied through direct pumping from main headworks pump house and also
by connecting some tube wells located in the zone directly to the distribution
system. A map showing the three zones of the present distribution system is
enclosed with this report for ready reference.
6.3
Need of the project:
Due to deforestation and low rainfall the water balance of the area has been
completely disturbed. In the year 1961 water table of Pushkar town area was
4.0 mts. where as at present it is 25 m. Water table depleted due to overexploitation of ground water. Central ground water authority issued notification
vide no 24/2001 and the Regional Director, Central Ground Water Board,
Jaipur
vide
letter
no
TS/Notified/CGWA/WR/2001/495
dt

recommended that in forthcoming period ground water potential may not be
sufficient in Pushkar Ghati area to sustain present level of ground water
exploitation. In view of this it has become necessary to meet the drinking
water requirement of Pushkar town from Bisalpur Dam as it is only a reliable
source of drinking water supply in Ajmer District.
6.4
Augmentation proposal of Pushkar under AUWSP
Keeping a view the non-availability of ground water as a source of drinking
water supply scheme, an augmentation proposal under AUWSP was framed
and got sanctioned from Govt. for supplying water to Pushkar town from Ajmer
city by pumping of water from Hari Bhau Upadhyay Nagar pump house
-47-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
through 50 year old 14” CI pipeline laid earlier for bringing Ganhera water to
Ajmer city. The estimated cost of this proposal was Rs.305.15 Lacks, the
details of which are also enclosed for ready reference. Under this scheme,
work of CWR and Pump House at HBU Nagar, and Installation of pumping
machinery in the pump house has only been taken up till now (approximate
expenditure – 28 lacks) and construction of two OHSR’s at IDSMT Colony and
Mela ground is proposed to be taken up. The distribution system shall be
taken up for laying as and when the availability in Pushkar town is improved.
This system also has not proved successful because of inadequate availability
of water in Ajmer city and especially in HBU Nagar area because of
involvement of double stage pumping at bus stand and Vaishli Nagar Pump
Stations. For supplying water to Pushkar town, pumping to a head of 80
meters at HBU Nagar Pump Stations would be required to cross the Pushkar
ghati hills which will involve huge expenditure on power. Since HBU Nagar
pump station is at the tail end of Ajmer city distribution network, therefore
availability of water for Pushkar shall always be doubtful .Hence to ensure
regular and uninterrupted flow of water to Pushkar town under gravity, an
alternative alignment of transfer main pipe line from SR-7 at Makhupura viaJaipur byepass-University Road –Pushkar byepass road up to village Honkra
Chhoti (only 11 km from Pushkar) has been proposed under this project.
6.5
Present Project
Since Phase-II augmentation of Ajmer water supply scheme from Bisalpur
Dam has been taken up under execution therefore the water demand of
Pushkar town has also been added in the carrying capacity of the
transmission main from Bisalpur Dam to Ajmer city up to SR-7 at Makhupura.
The present proposal is for providing transfer main pipeline from SR-7
Makhupura to Ajmer city which has also included the demand of Pushkar town
in the proposed transfer system. Since SR-7 is at a higher elevation water can
be transferred up to village Honkra (chhoti) under gravity up to about 11 kms.
From Pushkar town. Thereafter water shall be pumped to different reservoirs
in Pushkar town for being distributed in the city.

BISALPUR DAM – CAPACITY, RESERVATION AND WATER INFLOW
DETAILS
The capacity and reservation of water for various sectors in the Bisalpur dam
are as follows:
a. Capacity of Dam
: 893.91 M. Cum. (31,500 Mcft)
b. Reservation for drinking water
I. For Jaipur
: 317.20 M. Cum. (11,200 Mcft)
II. For Ajmer, Beawar, Kishangarh
: 141.26 M. Cum. (5,000 Mcft)
And enroute villages (Ajmer Dist.)
Total
: 458.46 M. Cum. (16,200 Mcft)
c. For Irrigation
: 226.40 M. Cum. (8,000 Mcft)
d. Seepage and evaporation
: 209.05 M. Cum. (7,300 Mcft)
As per the reservation made for Ajmer district in the Dam total quantity of
141.26 M. Cum. water for a year is to be drawn from the Dam in 365 days
thereby giving a daily drawl rate of 387 MLD
The demand for Ajmer, Beawar, Kishangarh, Nasirabad, Sarwar, and
Kekri,urban towns for both Phase-I and II i. e. water demand up to the year
2021 and rural water demand of peripheral villages of Ajmer and villages of
Beawar, Peesangan Panchayat Samiti up to the year 2027 is 292.62 MLD.
Demand of Fluoride Control Project for rural areas of Ajmer district including
water demand of Vijaynagar and Gulabpura towns up to the year 2027 is
81.17 MLD. Thus the total water demand of the Ajmer district comes out to
292.62 + 81.17=372.79 MLD. Now Pushkar town is also required to be fed
from Bisalpur Dam. Water demand for Pushkar town up to the year 2021 is
3.32 MLD raising the total water demand of the Ajmer district to above 376.11
MLD which is within the quantity of water reserved for the district.
As the reservation of water is 387 MLD, sufficient water is available for Ajmer
District. Hence no extra reservation of water is required up to year 2021.
The following table shows the likely quantity of water inflows in the Bisalpur
Dam based on the Gauge reading of Banas river at Tonk and inflows

Present Status of Ajmer Water Supply
8.1
EXISTING SYSTEM: The entire Bisalpur Water supply project was
contemplated and planned in two phases. The Phase-I was designed and
executed for the water requirement of 2002. The Phase-II is to be
designed for the requirement of year 2021. The phase-I of the project has
already been completed and commissioned in Feb 95, is sufficient only up
to the requirement of year 2002 as has originally been planned.
From the wet intake well, constructed at the dam it self, water is pumped to
Nasirabad town through 4 stage cross country pumping stations. The
schematic diagram showing the various pump houses, type and size of the
pipelines and the flow through them is enclosed for general overview. The
size of the pipelines varies from DN1700 mm PSCC to DN 1200 mm
PSCC diameters pipe lines. Major portion of the length is of PSCC pipes.
The scheme has been designed to pump 139 MLD raw water in 22 hours
pumping. The treatment works having 132 MLD capacities (water
treatment plant) is situated at Kekri from where water is pumped to Goyala
Pumping Station and from Goyala to Nasirabad head works. At Nasirabad,
the water is diverted to Kishangarh, Beawar, Ajmer and Nasirabad for
distribution.
The project was commissioned in the year 1995 with supply level of 150
lpcd for Ajmer town and 70 to 120 lpcd towns.

WATER SUPPLY SYSTEM IN AJMER CITY: Ajmer has a very old and
complex water supply network comprising of very old and dense areas and
the city extensions as well. The system has been expanded, upgraded and
augmented from time to time as required. The availability of water is
assured due to a reliable source like Bisalpur dam, despite the fact that the
local sources have either dried up or are no more dependable. In fact, the
Bisalpur dam water coming to Ajmer is recharging these traditional
sources. The topography uniform pressures and supply quantities have
always
been
a
challenge
for
the
PHED
engineers
in
Ajmer.
Old/rusted/leaking /worn out pipelines/appurtenances is a major issue in
Ajmer and due to congested lanes and dense inner city areas repairs and
replacement activities become very difficult. The geology is also very
typical on account of absence of soil cover and presence of fissured rock,
this prevents the leakages from surfacing.
-53-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
8.2.1 Transfer main to city from SR7 at Makhupura-Water received from
Nasirabad at SR7 Makhupura is transferred to city by old MS pipeline of
750 mm dia and 800/750 mm dia PSCC pipeline upto Alwar gate.
Presently about 70 MLD is supplied to Ajmer out of which nearly 50-55
MLD is through this new PSCC pipeline laid in 1996-97 and rest 10-15
MLD from old and worn out MS pipeline of 750 mm dia.
8.2.2 The present transfer mains are inadequate because of higher withdrawal
of water through them resulting in excessive loss of head up to Alwar gate
necessitating re-pumping of water at PS8, PS9, Subhash nagar, Vaishali
Nagar, Naka Madar, Bus-Stand Pump Stations. The new transfer main of
1000mm dia PSCC pipeline laid under RUIDP has not yet been properly
commissioned so far and is under trial run.
The methodology of consuming full gravity head up to Alwar gate and take
water in CWR’s at various pump stations and then supply water through
re-pumping needs re-thinking thereby requiring major improvements in the
transfer system. The practice of supplying water directly from the transfer
main has to be stopped and all supplies are to be made from SR’s. If repumping of water is required, it should be limited to a particular area. A
holistic view of transfer and distribution system is required to be taken
while suggesting changes in the existing distribution pattern.

Some other deficiencies of the existing system are as follows:1.
Some of the existing areas, where the storage and pumping facilities
have already been provided under Bisalpur Phase-I work, are being
supplied water only half an hour to maximum one hour due to
inadequate transfer main.
2.
Remote areas are not being provided with any kind of water facilities
due to inadequate size of transfer main.
3.
Direct tapping from rising mains is in practice in some recently
developed areas, which have not been provided with any pumping and
storage facility under Bisalpur Phase-I work. Such practices should be
immediately discontinued.
4.
In some of the areas, where the storage facilities (i.e. CWR/OHSRs)
have already been provided, the consumers are not getting ample
water with adequate residual pressure at their end. This is due to
continuous expansion of the zone along higher elevation etc.
5.
Rising main in some of the areas is presently being used as distribution
lines, which is not advisable, for efficient working.
8.5
A city map showing various SR’s and their zone of supply is enclosed at
annexure____ . Along with this map a statement showing various tappings
with names of OHSR/CWR/Direct Pumping along with 2001 population
served is also given so as to get a fair idea of present zoning of water
supply system in Ajmer city.

Technical Report
This project proposal pertains to transfer and distribution part of Ajmer and
Pushkar town, treated as one unit under JNNURM. Entire Ajmer district is
dependent on Bisalpur Dam water for its drinking water requirements as
availability of groundwater is very poor and quality of ground water contains
excessive fluoride and is not suitable for consumption. The total drinking water
required for both urban and rural areas of Ajmer district up to 2021 for urban and
2027 for rural is 376.11 MLD against which reservation of water for Ajmer District
in Bisalpur Dam water is 387 MLD (141.26 M. Cum. or 5000 Mcft). Thus
sufficient water is available in the dam for this project.
9.1 Bisalpur Phase-I has already been completed in 1995 and conveyance main
project for Phase-II water requirement has already been sanctioned and under
execution which will give 135.36 say 136 MLD at SR7 Makhupura near Ajmer. A
schematic diagram of pipeline from Intake well at Bisalpur Dam to Ajmer city is
enclosed to give an idea of existing and proposed transmission pipeline system
of Ajmer project. Water from SR7 Makhupura is to be supplied to Ajmer and
Pushkar towns through transfer main and distribution pipelines under this
project. The project area for Ajmer city is 85 sq. km. and Pushkar is about 10 sq.
kms. Some new areas beyond Ajmer and Pushkar municipal limits, where
development is taking place adjoining to Jaipur bye-pass, Beawar bye-pass,
Jaipur road, Beawar road, Pushkar bye-pass, University area, Lohagal and
Zanana hospital side has also been considered. Such areas are roughly 50 sq.
km. in total. The project has been designed for 30 years after allowing 2 years
period for completion of construction. Hence planning horizon year is 2039 with
intermediate stage at 15 years in 2024.
9.2 Population projection and water demand:
Population has been worked out for different years as per standards methods
given in CPHEEO manual and shown in chapter 3 and statements enclosed
there in for both Ajmer and Pushkar towns. Floating population in both the cities
-56-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
has been considered as given in chapter 4. Water demand has been worked at
135 Lpcd plus 15% provision for UFW or other losses of the system which comes
out to about 155 Lpcd for both Pushkar and Ajmer. This rate of water supply has
also been adopted in sanctioned transmission part of Bisalpur Phase-II project.
Floating population water demand has been worked out @40 Lpcd as per
CPHEEO manual plus 15% UFW or other losses i.e. 46 Lpcd. A detailed
statement of water demand for Ajmer and Pushkar has been attached at
annexure 9.2.1 and 9.2.2.
9.3 Pumps and Pumping Stations
No new pumping stations are proposed. Out of total water demand of 134 MLD
for the year 2021, 63 MLD water is required to be pumped in to OHSR’s/GLSR’s
which is about 47.5% of the total demand while rest of water shall be filled under
gravity in the reservoirs.

Centrifugal pumping sets of various duty conditions as per design
calculations shall be provided except at C V Nagar CWR, where low
discharge and high head submersible pumping sets are required to be
installed for Taragarh area.

Power control panels, valves, fittings, cables etc, shall be replaced and
rejunvated at each of pump houses where new pumps are to be installed.

Necessary provisions for up-gradation/renovation of existing pump houses
have been made as the existing structures are nearly 40 years old.

Repair/renovation of CWR and pump house at Kesarganj PS-9 shall be
carried out for which cost of making temporary pumping arrangements
have also been included to maintain water supply during repair period.

A new pump station at Honkra Choti for Pushkar town has been proposed
which is 9 kms from Ajmer(Saraswati Nagar). A CWR of 5.20 ML capacity,
equal to one day demand of Pushkar for breakdown period maintenance is
proposed to be provided at the pump stations. Water shall be pumped in
all OHSR’s of Pushkar town from this pump station. Direct feeder power
line of 33 KV shall be taken from Ajmer to Honkra Choti (9 km length) and
substation of 33/11 KV and 11 KV/0.4 shall be installed inside pump
-57-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
station compound. All such provisions have been made in pumping
machinery estimates of the pump station.
9.4 Design of rising mains
The localities which are situated at higher elevations shall be provided with water
supply through one stage pumping from CWRs pump station at Subhash Nagar,
PS9, PS8, Filter house, Vaishali Nagar, Naka Madar, Bus stand, C V Nagar, B K
Kaul Nagar, HBU Nagar. The pumping hours for 2039 demand has been taken as
20 and economical diameter worked out as per computer programme. All rising
mains shall be of DI pipes with non-return valves & discharge valves after the
pump house, so as to guard against back pressures. Economic design for each
rising main has ben given in design part and summary of rising mains provided
separately.
9.5 OHSR’s/GLSR’s
There are about 56 OHSR’s/CWR’s in Ajmer and about 2 in Pushkar and 2
proposed to be constructed. It has been proposed to construct about 8
OHSR’s/GLSR’s at Ajmer and one SR in zone 5 at Pushkar. This has been
worked out after working out wardwise demand for 2039 year and to work out
capacity required for 2021 even with restricted supply of 8 hours. Wherever the
zones are big, additional reservoirs have been proposed.
The capacities of OHSR’s/GLSR’s have also been checked with mass curve
analysis for 24 hour supply in 2039 and 8 hrs restricted supply in 2021. For SR’s
getting water under gravity incoming supply has been taken for 22 hours whereas
SR’s getting water through pumping hours of incoming water has been taken as
20 for demand of 2039 and the same rate of incoming water taken for 2021 also.
In this analysis it is seen that in most of the SR’s the capacity required is less
than the existing. For new proposed SR’s, higher capacity at 2 locations have
been proposed to be provided.
9.6 Design of distribution system.
Each SR serves as a zone, water is received by OHSR/GLSR by gravity (22 hrs)
or by pumping (20 hrs) and supplied in the zone. Computer run for the distribution
-58-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
network for all the zones has been done and the lines which are required to be
laid newly are worked out. A terminal pressure of 12m at the consumer end has
been kept. Detailed analysis of each zone with pipe details, junction pressure and
a map of each distribution zone showing existing pipelines and proposed pipeline
lines has been enclosed with a report.

TRANSFER MAINS PIPELINES FROM SR-7 TO AJMER AND PUSHKAR
Apart from shortage of water production and availability of water, inadequacy
and worn out condition of transfer main from SR7 Makhupura to Ajmer has
been a very big deficiency of Ajmer water supply system. An effort was made
under RUIDP Project to remove this deficiency by taking up laying of 1000mm
dia PSCC Pipeline from SR7 to Alwar gate but commissioning of this pipeline
got delayed and hence benefits from this pipe could not be availed so far.
10.1
Methodology of Proposed Transfer SystemEffectively present Transfer system reduces to one pipeline of 800/700 mm
dia PSCC pipeline through which 55-57 MLD water only is drawn up to Alwar
Gate and the balance 15-17 MLD water through old 750 mm dia worn out and
over used MS Pipeline which is to be abandoned and disconnected from the
system, because of its bad condition.
The following pattern is proposed to be followed in the new transfer pipes
lines under this project:-

The existing 800/700 mm dia PSCC transfer pipeline shall carry 46 MLD water
and feed all OHSR’s/GSR’s up to Alwar Gate and Topdara under gravity as
the outlet hydraulic level at SR7 is 537.5m and Hydraulic level at Kalyanipura
OHSR or C V Nagar OHSR (which are critical) is 517m and 512m. Thereby
giving a terminal head of 5.6 m and 6.2 m respectively

The newly laid 1000 mm dia PSCC pipeline under RUIDP (still not
commissioned) shall carry 85 MLD water and shall be used to connect all
CWR’s under gravity. Such CWR’s are Subhash Nagar, Kesarganj PS9,
Daulatbagh PS-8, Filter House CWR, B. K. Kaul Nagar, Vaishali Nagar CWR,
Bus Stand CWR’s and HBU Nagar CWR. For this, a new feeder pipeline of
700/600 mm dia in about 6 kms length and carrying about 28 MLD water is
proposed to be laid in the alignment of Alwar Gate to Bajrang garh circle near
Circuit house via Raja Cycle choraha, CRPF, Bus stand, Ambedkar Circle,
-60-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
Savitri College Chauraha so as to provide a separate and direct feeder to
Vaishali Nagar area and then to HBU Nagar CWR.

A new transfer main from SR7 to Pushkar town has been proposed to carry 51
MLD water having alignment via Parbatpura Circle to.0 Jaipur Bye pass Road
up to Ghoghra Village to University Tiraha on Jaipur road to University area to
Saraswati Nagar then to Zanana Hospital to Pushkar town along Pushkar
byepass up to village Honkra Choti (a place just 11km distant from Pushkar).
The size fo pipeline converges from 900/800/700/600/400mm dia in the end.
This water shall be transferred under gravity from SR7 to Honkra Choti Village
where it will be stored in a ground level CWR 5.2 ml capacity equal to one day
water demand of pushkar town, from where water shall be pumped into
OHSR’s of Pushkar town for supplying to the consumers. This new gravity
transfer main shall meet the future growing demand of Ajmer and Pushkar
town, thereby conserving electrical energy as well savings in expenditure on
energy bills.

A new branch having alignment from Parbatpura Circle towards Beawar for 15
MLD discharge up to Khanpura village Kuccha Track, then along this Kuccha
path up to Khanpura Bund, then dairy area road, then to Beawar road after
crossing railway line, then along Beawar road up to Transport Nagar, Bakra
Mandi and further areas. This gravity flow will also reach Beawar road and
cater to future development of Ajmer town on Beawar road.

Reasons to adopt above methodology:The pattern of above transfer system has been suggested keeping in view the
topography of Ajmer and practical considerations, some of which are given
below:a) The static head gained while crossing hills surrounding Ajmer city has
to be fully utilized in feeding OHSR’s so as to avoid need of re-pumping
of water in them.
b) All ground level CWR’s can be fed directly from SR7 under gravity
provided separate feeder lines are provided so that one CWR
requirement does not interfere with other CWR and there is no
operation of valves involved, so that human interference is reduced to
minimum or negligible. That is why separate feeder has been
suggested for Alwar gate to Bajrang Garh circle and from Parbatpura
circle to Beawar road or from PS8 to Filter/BK Kaul Nagar CWR or
Vaishali Nagar to HBU Nagar CWR.
c) An effort has been made to feed higher areas, prior to feeding to lower
level area. That is why new third transfer main has been suggested to
feed higher level areas of Jaipur bye-pass, Jaipur and Pushkar road
and University area under gravity from SR7 keeping in view the future
growth of Ajmer town.
d) Water to Pushkar town is to be provided without interference from
Ajmer water requirement and that too without requiring of 2 nd stage
pumping. In the suggested 3rd transmission water for Pushkar is to be
supplied under gravity up to 11 km distance from Pushkar town.
-63-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
e) First stage pumping has been adopted for very higher elevation of
levels 530m and above to be fed from CWRs and pump stations at
Subhash Nagar, Kesarganj PS9, Daulatbagh PS8, Filter and B K Kaul
Nagar CWR, Vaishali Nagar and HBU Nagar Pump stations. A total of
73 MLD out of 182 MLD of total water demand shall only be pumped in
single stage (about 50m) which is only about 40% which is quite low for
a hilly topography in a city like Ajmer.
f) The existing transfer main alignments along Nasirabad-Ajmer road
could not be followed on account of lack of space and finally leading to
lower levels and busy, heavy traffic and congested areas from where
approach to developing areas on beawar road, jaipur and university
area road would be difficult and against gravity. That is why a new
alignment through a developing and higher level area has been
suggested which has enabled to utilize the gravity head fully.

Water Supply Scheme for Ajmer & Pushkar Town under JNNURM

STORAGE RESERVOIRS
Bisalpur water supply system consists of 115 kms. high pressure PSCC
pumping mains with 22 hours pumping at 5 places. The major beneficiary
town of Ajmer and important pilgrimage town of Pushkar are at the tail end of
the transmission system from Bisalpur Dam. There is no provision of storage
of water for breakdown repair of pipelines or prevent maintenance of the
various valves and fittings and machineries installed in the pump houses and
the pipelines. This is a major deficiency of Bisalpur water supply project
for Ajmer city and district as a whole.
11.1
The experience of working of phase-I pipeline of this water supply project has
not been good and water supply to Ajmer city at times have suffered for two to
three days on account of repair of pipeline damaged because of bursting of
PSCC pipelines. The sizes of the pipelines are of the order of 1700, 1500,
1200, 800, 700 mm dia and normally it takes about 12-16 hours in the
watering and again minimum of 12 hours in charging of pipeline after repairs.
A minimum of 36-48 hours are required for replacement of burst/leaking pipes
thereby causing a disruption of 60-72 hours in regular supply of water to
Ajmer city. Because of suffering for the last above 4-5 years a general public
demand for creation of storage of water for the breakdown period has
constantly being raised by the administrative authorities and the public. In
view of this SE, PHED Circle, Ajmer vide is letter no SE/AJ/3 day’s
storage/06-07/3290-92 dt 16.01.07 has requested to examine the issue of
creation of 3 days water demand storage for Ajmer city and include the
necessary works and cost provisions in the JNNURM project report.
11.2
In such a long transmission system it would have been ideal if the filter plant
could have been located near the biggest user city that is Ajmer. But it was
not possible to do so because of the existing filter plant of phase-I being
located at Kekri and no fresh thinking on this issue was done. Simply a mirror
image of earlier Phase-I is adopted even in Phase-II. Now the only alternative
left is to create a storage capacity equal to the demand of the breakdown
period required for repairs of the pipeline system. This will also meet the
requirements of the preventive maintenance of the machineries and fixtures of
-69-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
pipelines such as butterfly valves, Air Valves, Scour valves, surge protection
devices etc. Thus to ensure reliability and sustainability and to keep the
system in running for all the days of the month, 3 days water demand storage
capacity is proposed to be provided at the end of the transmission system i.e.
at SR7.
11.3
As per sanctioned phase-II of Bisalpur project 135.86 say 136 MLD water is to
be transmitted at SR7 for meeting the water demand of Ajmer city, Pushkar,
peripheral villages of Ajmer and Pushkar. Under this project transfer pipelines
from SR7 to Ajmer and Pushkar and distribution pipelines with allied works for
both the cities are proposed to be taken up. Three days water demand works
out to about 408 ML and the present storage capacity available is about 25ML
only and one more reservoir of 75 ML is under execution. Therefore available
storage capacity is only about 100 ML and hence a balance storage capacity
of 308 ML is required to be created under this project.
11.4
Ajmer city is surrounded by hills and while coming form Nasirabad to Ajmer
city, hilly ridge line near Makhupura village is required to be crossed due to
which, service reservoir was located at this highest point while passing the
ridge at 551m level, thus utilizing the static head gained in distribution of water
in the city in areas below this level. The location of SR7 is about 8.1 km from
Alwar gate and the city has developed on Nasirabad road up to Hathundi
chouraha thus leaving a small distance of three kms up to SR7. In near future,
it may also get fully developed. Suitable site for construction of such a big size
reservoir is at SR7 where hilly area land all around, is available along the
existing reservoir and the storage reservoir of 308 ML can be constructed
after clearing and blasting of the rocky strata available at site. The advantage
of selecting the site of this reservoir near SR7 is that entire control of water
supply shall be at one place and static energy gained while crossing the hilly
ridge can be utilized to supply water to higher level areas of Ajmer city around
Jaipur bye-pass, Jaipur road, University road, Pushkar bye-pass road,
Lohagal road, area near Janana Hospital and to transfer water for Pushkar
town up to village Honkra Choti (a place 11 kms from Pushkar) under gravity.
For such big storage capacity reservoirs enough land space nearer to city and
-70-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
at such high level is not available. Therefore it has been recommended to
provide 308ML capacity storage reservoir at or near SR7 site.
11.5
Pushkar town shall receive water from village Honkra Choti by gravity from
SR7(a distance of about 29 kms). The levels in 5 km distance from Honkra
Choti are higher and the hydraulic gradient is not so high so as to cross this
higher ground under gravity. Therefore a pump station is proposed to be
installed at Village Honkra Choti with a Clear Water Reservoir of 1 day water
demand capacity of Pushkar town and water shall be pumped directly into the
two existing OHSR/GSR and two under construction OHSR and one OHSR
newly proposed under this project. This capacity of CWR shall be capable to
take care of the breakdown maintenance/preventive maintenance periods.
11.6
In the transmission system no pumping arrangements for de-watering of
pipelines in downstream of the existing pumping stations of the transmission
main have been proposed which is a necessity so as to conserve or avoid
wastage of precious filtered water. Such provision has been made under this
project so as to conserve water but necessary pumping machinery shall be
procured only after studying the behavior of the new pipeline proposed under
phase-II and necessity of installing such pumping sets for de-watering of the
transmission pipelines.
-71-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
12.0 PUMPING STATIONS & PUMPING MACHINERY
No New Pumping Stations have been proposed in Ajmer and Pushkar except
pumping station on transmission main to Pushkar town from Saraswati Nagar for
pumping water directly into OHSR/GLSR’s in Pushkar town. This was necessary
because of higher levels encountered in a length of about 5 kms from Honkra Choti
to Honkra Badi and thereafter and the Hydraulic Gradient Line being very near to the
ground levels. Hence the pumping stations which was proposed just at the entry
point into Pushkar town was shifted to Honkra Choti and water from this place
pumped directly into the service reservoirs of Pushkar. Necessary provisions for
acquisition/ purchase through negotiations of required land of 100m/100m for the
pumping station have been made in the cost estimates. Similarly provision of
erection of 33 kv power line from Ajmer (Saraswati Nagar) upto this pump station in
Honkra Choti (9 km length) and erection of 33/11 kv substation and 11/0.4 service
station within the PHED compounds have also been provided in the cost estimates.
12.1 The pumping station at Kesarganj (PS9) and Filter Plant along with their CWR’s
are nearly 32 and 52 years old and lot of loss of water takes place through them as
per the information made available during site visits. Therefore both these reservoirs
are proposed to be re-constructed in RCC after dismantling the existing masonry
reservoirs and pump houses. The new pump house proposed at these places shall
be framed structures of 15×7 m size or 30×7 m size. Temporary pumping
arrangement shall have to be made for maintaining water supply during reconstruction of these reservoirs and pump houses for which necessary mild steel
header pipelines for both suction and delivery side shall have to be laid and pumping
machinery installed temporarily under a temporary shed so as to pump water during
construction period of these reservoirs and pump houses which may be 6 to 8
months. Necessary cost provisions have been made in the estimates of pumping
stations or pumping machinery.
12.2 The reservoir and the pumping station at Kesarganj (PS9) has now become a
very crowded place with heavy traffic all around it and creates hindrance to the
general public in day to day life on account of frequent maintenance work of rising
-72-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
mains/ distribution mains. The local PHED officers also prefer to shift the site of this
pumping station to new site in Govt. college land for which the district administration
has also assured to provide land for construction of new reservoir or pumping station.
This site is one km away from existing PS9. This new construction of reservoir
largely depends on availability of Govt. land in Govt. College, Ajmer and involves
transfer of land from education department to the PHED. Since the infrastructure
proposed has be to be suitable for the horizon year 2039 therefore it is proposed to
constructed a new pump station at Govt. College, Ajmer land for which cost provision
for construction of new one day water demand capacity reservoir along with pump
house has been included in the estimates so that this work could be taken up as and
when the land is made available to PHED. Since the land belongs to Govt. of
Rajasthan and the land cost is to be borne by the state hence the provision of cost of
land has not been included in this project estimate.
12.3 All the existing pumping stations of Ajmer scheme are more then 45 years old
and the power control panels, cables, header pipelines and pipe fittings, sluice valves
etc. need replacement as the old items have become obsolete and spares are not
easily available. Therefore necessary provisions for re-junvation of these items as
well as rejunvation of the existing pump houses have also been made.
12.4 Most of the pumping machinery is very old and very poor in efficiency thereby
resulting in higher power consumption. The suction header pipeline is proposed to be
laid in such a way so that the pumps get water directly on a positive head from the
SR7 and the surplus water is allowed to fall in the CWR which will be above the
suction level of pump. This situation will enable the terminal pressure to be utilized
during pumping. However the design of the pumps have been carried out by taking
the worst situation of suction of water and delivering it into the OHSR/GLSR as per
the required head calculations. The pumping hours have been kept as 20 or less
keeping in the view the availability of the existing pumps and requirement of higher
pumping capacity during period of the year such as ORS/ or other peak demands
12.5 Non-return valves on delivery headers on each rising main just outside the
pump house shall in variable be provided. The design of pump sets at various pump
-73-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
station have been given in Volume-II of the report. However an abstract of the
pumping machinery is enclosed with this report which shows the existing pumping
machinery proposed to be utilized and the pumping machinery proposed to be
provided.
12.6 For Taragarh, pumping has been proposed from C V Nagar CWR and
submersible pumping set of 36 Cum discharge at 425m head coupled with 80kw
motor is required which shall be installed in a sump about 7m deep and connected to
the 150mm DI K-9 double flanged rising main about 7 kms length up to Taragarh
locality. Double flanged have been taken because of hilly terrain and high head on
which the normal gas-kit joint may not work. Water shall be supplied through
pumping from CWR at C V Nagar directly into the distribution system for a restricted
period of 8 hours, which have been kept as the pumping hours for Taragarh supply.

RISING MAINS
Rising mains have been designed for water demand of the year 2039 with 20 hours
pumping and economical size worked out for each design, which have been
enclosed in Volume-II of the report. An abstract of the rising main proposed is
enclosed with this report along with requirement of Non-return valves, Butterfly
valves and Sluice valves. In addition to the new proposed lines, some old rising main
pipelines which are leaking perpetually because they were laid some 45 years or
more periods are proposed to be replaced with new pipelines. Such examples are
600mm dia MS pipeline in Chamar Ghati from PS-8 to Babugarh (500m length) and
350mm dia rising main from PS-9 to Paharganj (2 km length) and 300mm dia AC
pipeline from PS-9 to Bada Peer which are proposed to be replaced and provided
with similar diameter DI K-9 pipes. Initially new lines shall be laid and commissioned
and thereafter old pipelines shall disconnected form the system. Wherever MS
pipelines are proposed to be provided the same shall be internally epoxy coated and
on outside it should have anti-corrosive coating and wherever it is in touch with
sullage water it shall be provided with concrete cover. All specials valves etc. shall be
double flanged and fitted with socket and spigot tail piece with dismantling joint so
that the fittings or valves can be opened subsequently during maintenance.

Mass Flow Analysis of the Reservoirs:
There are several existing reservoirs in twin city of Ajmer-Pushkar. The mass flow
analysis has been carried out to check the adequacy of the existing as well as
proposed reservoirs for the future use.
The detailed mass flow analysis has been included in the annexure 14.1 to 14.46 for
existing and proposed reservoirs.
There are some exceptions in the existing reservoirs wherein the capacity required is
more than the capacity of the existing reservoir for the year 2021 for which we have
considered 8 hour restricted supply for pumping and 22 hours supply for the gravity
mains.
The pumping hours for the year 2021 have been calculated by the back calculations,
considering the demand and pumping hours of the year 2039. After analyzing the
results we found that the pumping hours required for the year 2021 are between 16
to 18 hours. In some of the case these pumping hours are nearly 13 hours in place of
16 hours.
In such cases the analyses have been carried out considering the
calculated demand distributing into 16 hours.
For gravity flow system, the mass flow analysis has been carried out by considering
the 22 hours of flow in the year 2021 as well as year 2039. But for year 2021 the out
flow is restricted to 8 hours considering the worst scenario of the water supply. In
some of the reservoirs, the capacities seem to be less as compare to the required
capacities. This behaviour can be explained that after 2021 there are proposals for
24×7 water supply so if we increase the supply hours the storage capacity
requirement would be less and hence the existing capacity of the tank would serve
the purpose.
The details of the proposed reservoirs are as below-

DESIGN OF DISTRIBUTION SYSTEM
Distribution pipelines have been designed by taking each OHSR’s/GLSR’s as one
zone in both Pushkar and Ajmer cities. Some of the SR’s shall be directly fed under
gravity from the transfer pipelines from SR-7 while the remaining reservoirs which
are situated at very high levels shall be filled up by pumping from various pumping
stations. The network design has been carried out by using Water CAD Software and
network design, pipe report and junction report showing existing and proposed
pipelines have been worked out and enclosed in Volume-II of this report. Ajmer city
has been designed in 54 zones whereas Pushkar city has been designed in 5 zones.
3 zones in Ajmer and one zone in Pushkar are meant for new expanding and
developing areas of both the cities. Necessary provisions of pipe lengths for
replacement and renewals of chronically leaking pipelines have also been made in
the estimates. Wherever pressures are very high on account of high head of location
of GSR or OHSR the same is proposed to be controlled by installing butterfly valves
and sluice valves and adjusting the butterfly valves in such a way that the
downstream pressure is brought under control. At such points pressure gauge shall
be permanently installed and regularly monitored. Once butterfly valve is adjusted by
the Asst. Engineer, it should be locked in his presence and regulation of flow
(opening or closing) should only be done through the sluice valve installed near the
butterfly valve. Provisions have also been made for shifting of the main transfer
pipeline of 500mm dia and 400mm dia for Kesarganj which is come under the
Beawar side of Martindale Railway Bridge. The shifting of these two lines is highly

Metering and Measurement of Water Flows
Measurement of quantity of water production and its distribution to various
consumers in different areas and through various pipelines is a very important
aspect of a financially sustainable water supply scheme. Hence installation of
bulk water meters in production and distribution network is a important part of
Ajmer water supply project. This will also help in identifying the loss of water in
different units of the project, work out the over all quantity of Unaccounted For
Water (UFW) so that remedial action could be taken for reduction of UFW.

Disinfection through Chlorination
Introduction
:
Presently there are four methods of disinfecting water on large scale which are as
follows:
1.
Chlorination by Cl2
2.
Oxidation by Chlorine dioxide (ClO2)
3.
Ultraviolet rays
4.
Ozonation
Details of Disinfection
:
In following paragraphs the merits & demerits are explained.
17.1. Chlorination
It is being carried out for last more than 100 years. It is popular because of following
reasons.
a)
Potency
b)
Range of effectiveness as a germicide
c)
Easy to apply
d)
Easy to measure
e)
Easy to control
f)
Free from toxic or physiological effects
g)
Persists reasonably well
h)
Relatively inexpensive
However, it has following drawbacks.
a)
It forms trihalomethane (THM) with humic substance if present in the water.
-85-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
b)
It is corrosive and handled under stringent statutory regulations.
c)
It is ineffective against complex organisms i.e. cyst and protozoa.
17.2. Oxidation by Chlorine dioxide (ClO2)
In western countries chlorine dioxide is being used for the following reasons:
a)
It does not form Trihalomethane (THM) which is believed to be carcinogenic.
It prevents formation of THM even if subsequently Cl 2 is added in the
presence of humic substance.
b)
It does not form biomass in the pipeline carrying water.
c)
It has very broad spectrum kill.
d)
There are no stringent regulations as it is manufactured at site
However, it has following drawbacks:
a)
Chlorine, chlorate and chlorites are formed as by products though they are not
carcinogenic.
b)
It requires fine control so as not to exceed 0.5 mg/L dose.
c)
It is expensive.
d)
If it is applied in the existing system where chlorination is being used, there
are possibility of removing biomass from the pipeline. Because of removal of
biomass the bacteria like cryptosporidium may be exposed which are harmful.
-86-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
17.3. Ultraviolet Rays
Ultraviolet rays having wave length of 254 nm is bactericidal. The disinfection is
carried out without any chemical change in the water. However, it has following
drawbacks.
a)
Large particulate matter shields the bacteria in the water.
b)
It does not have residual effect in the water.
17.4. Ozonation
Though it is very power full oxidizing agent and THM is not formed when applied, it
has only half an hour retention period in the water. The byproducts formed are
formaldehyde, H2O2, bromate, bromomethane, brominated acetic acids and ketones.
The organic matter biodegrade early when ozone is removed from the water.
The cost of operating the plant is 10 times that of chlorination plant.
17.5 Recommendations
Amongst all above disinfectant chlorine is the best choice considering its
effectiveness and the cost.
The chlorination can be carried out by one of the following methods.
1)
Preparing weak solution of bleaching powder etc. and using it for disinfection.
2)
Preparing weak solution of electrolyzing brine solution.
3)
By adding chlorine either in the form of gas or solution prepared from
dissolving chlorine gas in small feed of water.
Various type of chlorinators used for the method mentioned at Sr. No.3 above, are
given in the accompanying table alongwith the details.
-87-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
Taking into account the capacity of the water supply system the total requirement of
Cl2 is as follows:
Water Supply
:
80
Mld
-
1st Phase
144
Mld
-
2nd Phase
Assuming 2 ppm dose at main reservoir inlet at SR-7 chlorine requirement is:
80 Mld  2 ppm
=
160 kg / day -
1st Phase
144 Mld  2 ppm
=
288 kg / day -
2nd Phase
For such a large quantity of chlorine requirement it is not advisable to use methods of
chlorination mentioned at Sr. No.1 & 2 above. It is advantageous to use vacuum
type chlorinator working on the principle of sonic flow.
These chlorinators are
available from 25 gm/hr to 10 kg/hr ranges. However for the range beyond 2 kg/hr
for continuous operation only chlorine tonner will be suitable as chlorine can be
withdrawn upto 7 kg/hr at a temperature of 20C. This type of chlorinator is suitable
to install directly on the tonner. 3 Nos. of chlorinator of 10 kg/hr capacity are
recommended for chlorination including 1 No. as a standby unit, for 1 st Phase until
commissioning of Phase – II of Bisalpur project.
17.6
After SR7 chlorination at following CWR/pump stations shall be done from
where total quantity of water supplied for 2021 and 2039 is also indicated.
Taking a chlorine doze of 2 to 3 ppm, the capacity of chlorinator to be
installed has been worked out as shown in the table

Control of UFW
Unaccounted For Water is a major problem of all water supply systems and
Ajmer and Pushkar are no exception to this. Serious and result oriented efforts
are required to control UFW through provisions of necessary equipments and
measurement of water flows in each unit of water supply system such as pump
stations, filter plant, CWR and OHSR/GLSR and finally in the distribution
system.
18.1. Under this project butterfly valves and sluice valves are proposed to be
provided on each off take to control the flow and measure the pressure so as
to ensure that only design discharge flows in a particular branch. Bulk flow
meter at each branch has not been provided as flow and pressures in a branch
shall be adjusted once in a while through butterfly valves by Asst. Engineer
and valved locked in his presence so that no one can tamper with the sitting of
flow. Any valve operation required in this branch shall be done through sluice
valve provided down stream of butterfly valve. The measurement of flow in the
branch line shall be done through portable Ultrasonic flow meter provided with
each
sub
division.
These
branches
while
terminating
at
each
CWR/OHSR/GLSR shall have bulk water meters with motorized sluice valve
with float valve on incoming pipeline with on/off switch to close the valve in
accordance with water level in the reservoir.
18.2. Thus, the quantity of water flow shall be measured at each reservoir. Water
flows in branches can also be measured through portable ultrasonic flow
meters and regulated through butterfly valves. Thus measurement of water
flows shall be an essential part of control of UFW efforts for which necessary
provisions have been made in this project.
18.3. In addition to it, provisions have also been made for removal of chronically
leakage points through relaying of DI pipelines of same sizes and providing
new pipelines in place of defective pipelines. After completion and
commissioning of 1000mm PSCC pipeline laid under RUIDP, the 750mm dia
-92-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
old MS pipeline is to be abandoned and taken out from site so as to save on
leakage of water. All direct connections in distribution lines from transfer and
rising mains shall be disconnected. All public stand posts shall be
disconnected as enough number of hand pumps are installed in the city. All
public connections such as in parks, water huts, fountains etc. shall be
metered in the name of local bodies maintaining them. Even in slums metered
water connections only shall be allowed. Whenever old connections are
shifted, it shall be only through quarter inch ferule. All valves and fittings shall
be checked periodically and leakages removed through effective preventive
maintenance which will be an essential part of maintenance contract.
18.4. Installation and reading of meters on all domestic, industrial and commercial
connections and raising of bills based on consumption of water and collection
of revenue shall go a long way for both conservation of water as well as
reduction of UFW. For this, work of providing and installing meters is
suggested to be executed by providing and installing new meters along with
their maintenance and running for a period of 5 years so as to keep the meters
in working condition. Similarly work of meter reading, billing, collection of
revenue area-wise in city should also be contracted or privatized as a service
contract in the first instance. Both these measure will give good results towards
control of UFW.

Proposed steps to change over to new transfer system
Ajmer has always been suffering on account of less production of water and
deficiency in production is sought to be covered through restriction of supply
hours. Water demand for 2009 for Ajmer city is about 97 MLD against which
only 70 MLD is being supplied. This quantity should be increased to 97 or 100
MLD through reduction of over drawls in rural areas, Beawar and Kishangarh
towns. Then the following steps should be taken to shift to the proposed
transfer system.
1. Firstly commission 1000mm PSCC pipeline laid under RUIDP fully and take
71% of Ajmer water supply through this line i.e. 69 MLD out of total 97 MLD
and 28 MLD through existing 800/700mm PSCC pipeline.
2. Install bulk flow meters on both 1000mm and 800mm PSCC pipelines or
measure the flows being supplied to city by portable ultrasonic flow meters
and through setting of butterfly/sluice valves.
3. Connect 600mm dia two old CI and DI pipelines to 1000mm PSCC new
pipeline through 1000mm dia MS pipeline. Either disconnect or close the valve
from existing 700mm dia PSCC pipeline, install pressure gauges at each
pipeline and keep a record of pressure on 1000mm, 700mm, 600mm dia CI &
DI 2 pipelines and 600mm dia Mayur SR pipeline.
4. A L Sethi Nagar SR and Subhash Nagar side OHSR’s through 14” CI one
pipeline be fed from 800mm PSCC pipeline and feed Adarsh Nagar GSR,
Dholabhata OHSR or all OHSR’s up to Alwar Gate from 800/700 mm dia
PSCC pipeline and pressure measurement points be provided on lines and
measurement of flows in each branch should be carried out through Ultrasonic
flow meters.
5. Subhash Nagar CWR pipeline 14” dia to be shifted on 1000mm dia new
PSCC pipeline and disconnected from 800/700 old PSCC line. All direct
-94-
Water Supply Scheme for Ajmer & Pushkar Town under JNNURM
supply from 800/700 pipeline to be disconnected as the process of connecting
feeder to OHSR’s progresses and completed. If needed direct feeder pipelines
from related SR’s to these direct lines be laid and connected.
6. 300mm dia DI pipeline to Topdara SR from 700mm dia PSCC be laid and
commissioned. Similarly 400mm dia pipeline from Mayur Colony SR to
Nasirabad road toward Martindale bridge laid so as to facilitate disconnection
of direct supply through 600mm old CI pipeline.
7. After stabilization of this system, the old 750mm dia MS pipeline be
disconnected and discarded.
8. The DI pipeline of 700/600mm dia from Alwar gate to CRPF-Jaipur roadBajrang circle be laid and commissioned so that Vaishali Nagar may get
additional water.
9. The DI pipeline of 600/500/400mm dia be laid from Parbatpura crossing to
Beawar road via Beawar Bye-pass, Khanpura village and Dairy area and then
to Beawar road.
10. Third transfer main 900/800/700/600/400mm up to Honkra Choti village near
Pushkar town can be separately taken up and transfer system completed as
proposed.
The above steps, if followed chronologically will ensure smooth transfer to
new transfer system and save on power charges conserve water and control
UFW.

Institutional Arrangements, Capacity building and I. E. C. Activities
1. Institutional arrangements
Water supply and sewerage projects are part of Public Health Engineering and
therefore should be dealt with by PHED Engineers. Therefore separate unit
under SE, PHED with 4 to 6 Executive Engineer and one Account Officer to
maintain both Capital and Maintenance Accounts be created which will be
responsible for planning, preparation of project, execution, maintenance and
accounting of both water supply and sewerage projects. This unit shall be under
control of Ajmer Nagar Parishad for maintenance works and financial
management of scheme but technical supervision shall be of Additional Chief
and Chief Engineer PHED. Officers from line department that is i.e. PHED shall
be deputed for fixed periods to such created unit under local body so that there
is sufficient scope of change and interchangeability.
2. Capacity Building
Sufficient provisions are required for training of operational staff specially
relating to control panels and electronics gadgets. Although maintenance is
proposed to be carried through private contracts, yet training of staff related to
operation of various equipments is proposed to be provided at manufacturers’
workshops or factories. Such trainings shall be given to workmen level staff,
middle level supervisors and Asst. Engineer and Executive Engineer levels for
which provision of training fees, T.A. & D. A. and expenditure on training
material has been made. The type of trainings required shall be decided after
discussions with PHED or other big organizations engaged in similar activities
like Delhi Jal Board or corporations of metro cities of the country.

3. I. E. C. Activities
To generate awareness about healthy environment especially water supply and
waste water management in our society is a prime necessity of our times.
Although people know these things yet they seldom follow it in day to day life.
For a sustainable water supply system, people should know how much it costs
them, what are advantages of conservation of water and avoid wastage of water
etc. A massive I. E. C. programme is proposed to be taken up through Radio
talk, T. V. advertisements and T. V. shows, workshops etc. for which necessary
provisions have been made.
