Metrowater to sell treated waste water for construction
In these days, when freshwater resources are becoming
scarce, Chennai Metrowater has come up with the idea of supplying
treated waste water to the construction industry.
The
industry needs close to 20 lakh litres of water daily for various
construction activities. Of this, nearly 6 lakh litres are estimated to
be required for major construction sites along the IT corridor. In a bid
to ease the burden on groundwater, Metrowater has proposed to build
another treatment plant to once again treat the water from the treatment
plant in Perungudi.
The water agency is already
supplying about 30 million litres a day of recycled water to industries,
the Chennai Corporation, and the Tamil Nadu Road Development Company.
The Rs. 56.6-lakh plant will treat six lakh litres per day, which will
be provided to the industry.
Though the treated waste
water is good enough to be used directly, the water agency will treat
it again to ensure quality production of concrete and safe handling.
With
Metrowater planning to complete the construction of the additional
plant in November, the recycled water will be available for Rs. 20 per
kilo litre. Besides saving freshwater sources, the project also aims at
meeting the expenditure towards treating sewage. Construction
contractors may register themselves to get the service, the release
said.
