Civic:Road, which was dug for the underground drainage work in Pudukottai, being re-laid on Monday. —
PUDUKOTTAI: Work on underground drainage is likely to be completed by March and officials of the Tamil Nadu Water Supply and Drainage (TWAD) Board, which is the implementing agency, have been making an all-out effort for the completion without any further cost or time over-run.
The work is executed under ‘underground drainage scheme,' which is being implemented by Tamil Nadu Urban Infrastructure Development Fund (TNUIDF), at an outlay of Rs.48.16 crore.
This includes the State Government's grant of Rs.24.35 crore, the municipality's share of Rs.11.76 crore and a loan of Rs.12.05 crore.
According to TWAD officials, a good part of the work has been completed so far. Pipelines had been sunk to a cumulative length of 127 km so far, against the total 159 km.
“We have divided the entire town into two major zones – one to the left and the other to the right of the main streets- for ensuring expeditious execution of the project,” say sources.
The proposed adoption of the ‘activated sledge process' is the special feature of the scheme. Explaining its advantage, the sources said that this modernised treatment technique reduced both duration and space .
The modernised technology involved just 24 hours for treatment of sewage against the conventional method with a prolonged duration ranging anywhere between eight and ten days. Separation of the sledge from the water and mixing of chlorine with water would be some of the techniques planned to be taken up.
These techniques would be more eco-friendly and expeditious, sources said.
