Nagapattinam municipality to get underground sewer system soon
Rs. 60.68-cr. scheme under Tamil Nadu Urban Development Project
Two major towns, Velankanni and Sirkazhi, in the
district could soon get underground sewage systems as the district
administration has decided to forward detailed project proposals to the
government.
Speaking to
The Hindu
here, Collector T.Munusamy said following the successful implementation
of underground sewage system (UGSS) at Mayiladuthurai, the district
administration has decided to implement a similar scheme in
Nagapattinam.
Nagapattinam is a selection grade
municipality and a district headquarters. The area of the town is 14.90
sq km and the population as per 2001 census is 92,525.
Currently,
sewage from houses are let into open drains and finally discharged into
the Vettar and Devanathi rivers. The government has sanctioned the UGSS
for Nagapattinam municipality at an estimated cost of Rs. 60.68 crore.
The scheme is funded under Tamil Nadu Urban Development Project III.
All
the 36 wards of the Nagapattinam municipality will be covered under the
system. The scheme is designed for the base year (2009) population of
1, 02,987 with an intermediate and ultimate year of 2024 and 2039 with
estimated population of 1, 25,895 and 1, 53,899 respectively, the
Collector said.
The sewage contribution is fixed as
100 litres per capita daily. The sewage generated is 12.59 million
litres daily and 15.39 million litres daily respectively for
intermediate and ultimate stages.
The town is divided
into 8 zones. The sewage collected from all the streets by sewer lines
of pipes ranging from 200 mm to 600 mm (UPVC/RCC) to a total length of
90,301 metre with 3,418 manholes, six lift manholes, and seven pumping
stations. About 11,034 domestic connections will be provided.
The
collected sewage will be treated at two separate sewage treatment
plants, one with a capacity of 2.96 MLD at Nagore and another of 9.63
MLD at Nagapattinam (Extended Activated Sludge Process) located as part
of the municipal compost yard at Nagapattinam and part of the municipal
park at Nagore (Extended Activated Sludge Technology) respectively.
The
sewage treatment plant is designed for the intermediate stage total
capacity of 12.59 million litres daily. The treated effluent will be
discharged into Vettar and Devanathi River for which consent for
operation from Tamil Nadu Pollution Control Board has been obtained in
March 2012.
The work is being executed in six
packages with collection system comprising four packages and sewage
treatment plant comprising two packages, said the Executive Engineer of
TWAD, U.Murugaiyan.
At present 95 per cent works of
collection system are complete. Around 76 per cent works of sewage
treatment plant at Nagapattinam and 53 per cent works of sewage
treatment plant at Nagore are over. The scheme is expected to be
completed by the end of November 2014.
The
underground sewerage scheme is a boon to the residents, and Nagapattinam
will become free from pollution and environmental-friendly district in
the State, said the Municipal Commissioner, R.Murugesan.
