Mumbai will have its first desalination plant in the coming months,but the BMC project,costing more than Rs 15 crore,will not be used to treat water for drinking purposes.
The civic administration will adopt an expensive project for desalination. However,the money spent might not be worth as the water will be used only for non-potable purposes. As many as 18 companies have shown interest in the pilot plan. The location,however,has not been decided yet.
Desalination techniques can be used to treat water and make it potable,but we will first experiment with non-potable water, municipal commissioner Swadheen Kshatriya said.
However,he admitted that the desalination of water for non-drinking purposes was more expensive than sewerage recycling. Civic officials had already pointed out that the project would only serve as a showpiece for political parties and not solve the water woes of the city.

Desalination costs Rs 50-60 per 1,000 litres; the water should then be processed further to make it potable. A one-million-litres-per-day plant would cost at least Rs 10 crore. Whereas,treatment of sewerage water costs around Rs 10 per 1000 litres.
There is a need to explore all available techniques to counter water shortage. Since Mumbai is surrounded by sea,we should explore the possibilities of treating seawater, Kshatriya said.
