When the Rs.1,295-crore Combined Water Supply Scheme (CWSS) for Vellore district with the river Cauvery as source is completed by the middle of next year, the district will get 181 million litres a day (MLD) of water, thereby helping to augment drinking water supply. So far, 25 per cent works have been completed under the scheme, according to Collector P. Sankar.

“The works are expected to be completed by July 2014. We are taking steps to expedite the works and complete it on time. Out of the total 308 km, pipelines have been laid for 78 km and of the total 170 ground-level storage reservoirs, 58 have been constructed and 33 are in progress,” Mr. Sankar told reporters after reviewing the scheme works at Ambur and Melvisharam on Friday.

The scheme – CWSS to Vellore Corporation, 11 municipalities, five town panchayats and 944 rural habitations in Vellore district – began in March 2012. It has been designed to draw 215 MLD of water from the Cauvery at the upstream side of Chekkanur barrage and downstream side of Mettur reservoir.

“This is keeping in mind the requirement of water in 2030. Initially, 181 MLD water will be obtained through the scheme,” the Collector said.

The water would be treated at a treatment plant proposed to be constructed at Thottilpatti at Mettur (Salem district).

The water would then be pumped to two Master Balancing Reservoirs located at a distance of 80.7 km at Kadathur in Dharmapuri district – each of 45-lakh-litre capacity – through booster stations of Komburankadu, Palakkanur and Muthampatti, officials of Tamil Nadu Water Supply and Drainage (TWAD) Board said.

From here, water would be supplied up to Arakkonam for a distance of 228 km , officials said.

“From Kadathur to Arakkonam, there is no need for pumping the water as there would be gravitational flow. The reservoir is coming up at an elevated level - 269 metres high from base - to facilitate gravitational flow,” Mr. Sankar explained. At each branch, water would be pumped from sumps to overhead tanks, he said.

The scheme was being executed in three packages - from the headwork at Mettur to Kadathur, from Kadathur till Vaniyambadi and from Vaniyambadi to Arakkonam, he said. When completed, the scheme, would benefit a population of 18,68,371.

Outlining the priorities as of now, Mr. Sankar said, “We are taking up the works to lay pipelines wherever we have obtained permission. Next, we are looking at constructing sumps with larger capacity and similarly overhead tanks,” he said.

The Collector reviewed the works at Vengili yard where internal and external coating (guniting) of pipes with cement mortar was being carried out, pipe-laying works at Vinnamangalam near Ambur and construction of ground-level storage reservoirs at Ambur and Melvisharam. Rajamani Susilan, Superintending Engineer of TWAD, and executive engineers A. Anbazhagan, K. Sivarajan and Saravanan were present.
