Tender for Chennai RO water-reuse plant feasibility

Bids are due by 22 February 2012 for a prefeasibility study for a 45,000 m³/d membrane-based tertiary wastewater treatment plant in Chennai, India.

Chennai Metropolitan Water Supply & Sewerage Board (CMWSSB) issued a consultancy tender (CNT/ICB/GOTN/TTRO/CON/ 2146 /2011-12) on 9 January 2012.

The successful tenderer will conduct prefeasibility studies, preparation of detailed project report, bid documents and evaluation of bids for a reverse-osmosis tertiary treatment plant to be built at Koyambedu.

A CMWSSB official told the Times of India that this would be a pilot project.

"We supply 50,000 m³/d of pure water to industries. This can be saved if treated sewage is supplied to them. They can use it for non-drinking purposes, including for toilets. Even commercial establishments can be supplied this," said the official. "We have to see how it runs and also study the economics. Then we can build additional plants in 2-3 years."
