Metrowater officials said materials had been sought for the work to commence. The new plant too will employ the reverse osmosis process. But it will have additional components in the pre-treatment process such as dissolved air flotation and ultra filtration, to keep out sea algae and other particles in seawater from hindering the production process.
The State government has sanctioned Rs 6,079 crore for establishing a 400-MLD reverse osmosis desalination plant at Perur on the East Coast Road, according to the GO issued by the Municipal Administration Department last week.
The funds were sanctioned to give effect to the recent announcement made by Chief Minister Edappadi K Palaniswami under Rule 110 in the Assembly. The plant, being set up to meet the increasing water demands in Chennai city, is funded by the Japan International Cooperation Agency.
The JICA will give Rs 4,267.70 crore in two tranches – i.e., Rs 1,744.40 crore as Transche-I and the balance as Tranche-II. The operation and maintenance cost for 20 years is estimated at Rs 20,174.14 crore and the land lease cost at Rs 82 crore for 30 years; that is, Rs 1,000 crore per annum, on an average.
Krishna’s water supply to Chennai remains as elusive as ever, as it will take 10-15 days for the city to start receiving its share, said officials from the Water Resource Department (WRD).Though the two main reservoirs across Krishna river in Andhra Pradesh, Srisailam and Somasila, have crossed the mark of transferrable water levels, the third reservoir, Kandaleru is still not full.
CHENNAI: The Tamil Nadu government will ensure Chennai city has a permanent water supply capacity of 870 million litres a day (MLD) in the next five years by constructing two more desalination plants of 150 MLD and 400 MLD at Nemmeli and Perur and two 45 MLD tertiary treatment reverse osmosis plants, municipal administration minister S P Velumani announced on Friday.
Addressing the Times of India water conclave aimed at making Chennai water positive, the minister said 260 MLD of waste water would be recycled and diverted to industries to replace the potable water supplied now. Besides new sources such as the Thalakanacheri quarry, Nallambakkam quarry and Pulipakkam quarry with a potential of 60 MLD had been identified. The feasibility study for extraction of water from these sources was on.
Niti working out proposal to set up desalination plants along coastline to tide over water crisis – India
The Niti Aayog is working on a proposal to set up a string of floating desalination plants in marine waters along the country’s over 7,500-km coastline, with a view to tide over the water crisis being faced in major urban centres of India.
On Thursday morning at 8.30, the Chennai airport observatory had received 29.4 mm rain over the past 24 hours, according to the IMD’s Chennai office. Nungambakkam station got 26.4 mm over the same period.

To Overcome Water Crisis, India Plans To Build Desalination Plants Along Its 7,800-km Coastline – India
In the near future, 40% of the country is looking at water scarcity. Ministers are starting to wake up to the problem. Arvind Kejriwal announced rainwater harvesting processes that will be carried out in Delhi.
Finance Minister Nirmala Seetharaman also announced government’s plan to provide potable water to each rural household by 2024. And now, a nationwide ambitious project of desalinating sea water seems to be in the pipeline.
A new desalination plant will come up in north Chennai to cater exclusively to thermal units of Tangedco. State power minister P Thangamani announced this in the assembly on Thursday while replying to the debate on demands for grants for the electricity department.
Another plant with 150 MLD capacity will come up at Nemili. The one planned in North Chennai is the fourth desalination plant in Chennai. There are two thermal units with 600MW capacity each in North Chennai. The new unit will be set up at a cost of Rs 200 crore and will have a capacity of 10 MLD.
