Water crisis

more-in

Chennai Metro Water tankers take two to three weeks to turn up (“A cry for water”, June 20). Private tankers are fleecing the public and demanding ₹3,000-5,000 for one lorry. This would not have been the situation if at least 20 water bodies in the city had been maintained properly, if they had not been encroached on, and if sewage and garbage had not been dumped into them.

In 2013, it was reported in Nature that scientists had discovered huge freshwater reserves in aquifers under oceans. This water has been shielded from seawater by a protective layer of clay and sediment. The volume of this water is estimated to be higher than the water we have extracted from the ground in the last century apparently. At present, government and private oil firms spend millions of dollars to drill oil. It may be worth spending part of the money to drill into the seabed to extract this water, which has become such a precious commodity.
