Chennai to get desalination plant to stall drought
As part of its plans to deal with the drought, the Chennai Metropolitan Water Supply and Sewerage Board (Metrowater) has announced the setting up of a 300-million-litre-per-day desalination plant that will operate on a build-own-operate-transfer (BOOT) basis to ensure reliable water supplies to the city.
The total cost of the desalination project is estimated at Rs 1,500 crore; its implementation will be based on international competitive bidding.
Work is also expected to commence on a 50-million-litre-per-day tertiary-treated reverse osmosis plant to provide uninterrupted and exclusive water supply to industries. Tenders have been received for a Rs 160 crore plant at Kodungaiyur to treat secondary treated sewage. The water will be supplied to industrial units in Manali.
A third project, which is part of the water management plan to augment water supply through the conjunctive use of surface and groundwater, is also in the pipeline.
This project, aimed at tapping groundwater sources, will involve the desilting of tanks and lakes. It is expected to cost Rs 600 crore. The state government will approach the World Bank for assistance for this project.
Through the third project, water will be supplied to urban areas adjacent to Chennai. The project will involve the construction of a check-dam at Thirukandalam across the Kosasthalaiyar, improvement of the Vallur anaicut, use of groundwater from the Araniar-Kosasthaliayar (AK) aquifer, and the desilting of the Ambattur, Korattur and Rettai Eri tanks.
