Septage Management under AMC at
Present
• Each year about 10% septic tanks i.e. 7000
gets full and need cleaning.
• Mechanical: AMC operates two no of cesspool machines at present. Lat year AMC got
only 940 cess-pool orders.
Manual: About 6000 septic tanks are
cleaned in the last year manually on private
basis. Septage is flown into storm water
drain causing pollution of rivers and waterbodies.
Difficulties faced by AMC at present for
Septage management
•
•
•
•
•
•
•
Only two functioning cess -pools which can cater only 6-8 orders
per day. Lack of ability of AMC to cater entire orders and
pendency problem.
No access too narrow lanes and gullies as the cess pool can not
enter due to big size.
High expenditure per trip of cess pool and very subsidized rate
No scientific disposal of septage at present
People do not follow practice of construction of soak pit along
with septic tank though it is mandatory as per TBR-2004,
overflow pipe of septic tank is put into storm water drainage
leading to pollution of water bodies of city and international
water.
Relatively large number of kaccha latrines: As per ILCS survey
there are about 18790 kaccha/un sanitary latrines. As per The
Tripura Pollution Control Board Survey 1145 latrines along the
Haora river have direct connection into the river

Main reasons of pollution of Haora river and
other water bodies of Agartala City:
• Practice of manual cleaning of septic tanks and
throwing of the septage thus collected into the storm
water drainage which ultimately flows to Haora and
other water bodies of the city.
• Lack of soak-pit In most of the households there is no
soak pit attached to the septic tank for soaking the
overflow of septic tank. The overflow is directly put into
the storm water drainage which ultimately flows to
Haora and other water bodies of the city. As per the
Tripura Building Rule 2004 soak pit is mandatory for
all the septic tanks.
• Large number of kaccha latrines. There are about
20000 kaccha latrines in the city. Most of these
latrines are directly connected with the storm water
drainage or some water channels or river.
Action Plan of Agartala Municipal Council for
Scientific Septage Management
• Sewerage Scheme Under North Zone
• Plan for Mechanical Septage Collection
under other three zones of AMC
• Use of high power De-Silting Machines for
mechanical drain clearance
• Integrated Low Cost sanitation (ILCS)
Scheme implementation under AMC
Sewerage Scheme under AMC
• Rs 102.21 Crore Scheme under progress
JNNURM for North Zone of Agartala
Municipal Council –to be operational by
March 2014. Almost 70 % work completed.
95 km sewer line network covering entire
North Zone of AMC, 3500 manholes, 9
pumping stations, 11 lifting stations, one
Sewerage Treatment Plant with 8 million liter
per day sewerage processing capacity. The
components are1. Sewerage House Connections and pipelines
2. Sewage Pumping Stations
3. Sewage Treatment and Disposal Facilities
Photographs of Sewerage
Scheme(JNNURM)
Plan for 90-100% Mechanical Septage
collection under AMC
• Aim is to clear around 6000-7000
septic tanks mechanically by Cess-pool
Machines ( Suction Pumps with
Tankers) and treat the septage in
Sewerage Treatment Plant (JnNURM)
• At present two no of cess-pool
machines are operating. Two split type
cess-pools and two conventional cess
pools to be procured by the end of
December 2013 so as to cater daily 2025 orders.
Plan for septage/sewage treatment
• 8 million liters per day Sewerage Treatment
Plant(STP) under Sewerage Scheme JNNURM to
become operational by December 2013
• The STP plant is enough for the treatment of all the
septage about 20-25 Septic tanks daily along with
the sewerage load of the entire North Zone.
Use of two high power De-Silting
Machines
• Agartala Municipal Council has
recently procured two numbers of
high power De-silting Machines
with the cost of Rs. 2 crore.
• Machines are being used to de-silt
all the major drains of Agartala
City at present
• The Sewage thus collected is at
present dumped into the landfill
but subsequently treated in the
new Sewage Treatment Plant of 8
MLD capacity which will be
operational, under the Sewage
Scheme under JnNURM under
North Zone of AMC by December
2013.
ILCS Scheme implementation
under AMC
• 18970 no of Integrated
Low
Cost
Sanitary
Latrines
are
being
constructed to convert
eliminate all the dry
latrines
under
Integrated Low Cost
Sanitation
Scheme
(ILCS) of Ministry of
HUPA, GOI
• Already 2500 completed
• Target to be completed
by 31st March 2014.
Aims before AMC
• To create public awareness for cleanliness, &
sanitation
through media, small movie clips,
school
programmes,
rallies,
distributing
pamphlets, leaflets etc
• To clean all the septic tanks mechanically by the
end of this financial year.
• To treat scientifically entire sewage/septage by the
