LAKE CITY …….. situated in southern Rajasthan is one of the
Beautiful place’s in India
UDAIPUR from years is known for its beautiful lake ,forts and has
been a major tourist spot …….
Lakes in Udaipur
•Fateh Sagar
•Pichola Lake
•Rangsagar lake
•Swaroopsagar Lake
•Badi Lake
Our Main Concern :
•Fateh Sagar Lake
The Lake is situated in the north of Udaipur city, as apart
of the western lake frontage. The lake was constructed in
the year 1678A.D. and then renovated in 1889A.D. by
Maharana Fateh Singh. The dam of this reservoir is
720m in length and about 100m in breadth. The lake has
a catchment area of 53.66km.The greatest depth of the
Lake lies near the middle of the dam i.e. 13.4 m. The
total spread is 4.0 sq. kms.
•Pichola Lake
A Banjara chieftain initially constructed the lake in the
14th century. Rana Udai Singh further raised its
embankment in 1560 A.D. The water spread of the lake
is 6.96 kms. And has a maximum depth of 10.5 m
towards the west where the Kotra River drains into the
lake. The lake forms the main source of drinking water
for the city. The river Sisarma, a tributary of the Kotra is
the chief source of water to the lake
But ……………………
in recent years the pollution
(majorly water pollution ) level has increased so much that
udaipur is loosing its scenic beauty …………..

• The aquatic species are
suffering the most. Fishes are
dying because of non availability
of Oxygen since the water
surface is covered with
watercress .
• Also chemical water is directly dumped in the water bodies without any
treatment which is affecting aquatic life.
•Accumulation of bioaccumulative and non-biodegradable pollutants in animal
bodies which is leading to the death of aquatic animals and plants and this effect
is than continued in the food chain
Effect on HUMANS :
•Increased incidence of tumours, ulcers due to nitrate pollution.
•Increased incidence of skin disorders due to contact with
pollutants.
•Increased incidence of constipation, diarrhea and infections to
intestine.
•Dangerous effects on growing foetus in pregnant women.
•Concentration of pollutants due to bioaccumulative pesticides.
through secondary and tertiary food chain in case of non vegetarians.
•Still births, abortions and birth of deformed children.
•'Blue baby' disease caused by methane globinemia - which
results in asphyxia (reduced O2 supply).
•Reduced activity of immune system.
•Loss of memory power and reduced mental sharpness.
•Water borne diseases like jaundice, hepatitis, gasteroenteritis
will be more prevalent due to water pollution.
•Reduced bone development and muscular development.
•Reduced male fertility.
•Shifts in physiological cycles of human body.
Udaipur Purification Plant:
There are 3 main water purification plants in Udaipur :
1) Doodh Talai
2) Jaisamand
3) Udaisagar
We visited Doodh
Talai plant

In this step chlorine gas and alum are
added in certain amount of ppm
depending on tubidity of water.

After first step treatment water is collected in the centre tank and
allow to stand. So that the flux formed is seperated. Then this water
is pumped from bottom to top in outer tank, known as
sedimentation tank. These tanks are 20 ft deep.
Pic-5
Pic-6
Water from the sedimentation tank is passed into these two
filter bed. In these bed the water is passed through the bed of
sand and gravels.
By the end of these processes the water is free from macroscopic
pollutants.
Pic-7
This water is transferred to a storage tank where chlorine gas is
passed through it in optimum amount.
Pic-8
This collected water is pumped to different parts of the city.

Measures going on in the city to control this\ 
• Rajasthan Patrika is running “AMRATAM JALAM”
program which is receiving great response from the public
• Jheel Sanrakshan Society, Udaipur too is working
along with the public cooperation and working at a great
pace.

• Recycle as much plastic and other materials as possible.
•Dispose of all unused household hazardous wastes at
your local disposal site.
•Use NATURAL alternatives.
• Put litter into garbage cans, never throw it into storm
drains or the street.
