Chennai Water Crisis: Day Zero

Manohar Khushalani stated that the big factors that have led to this crisis in Tamil Nadu are deforestation and mining, in other words construction of buildings for development is in the process.. These types of constructions have halted the recharge of lakes and reservoirs that supply water to the households, and since the recharge has stopped, the major lakes and reservoirs have gone completely dry. Even the amount of rainfall has been declining and that amount was not enough to recharge the lakes.

Sewage treatment is also very necessary because otherwise rivers get polluted by the sewage. Sewage farms have been replaced by construction building. Dilution of water has become impossible after people started covering the gutters. These stormwater drains have been made by using public tax money and no one has the right to block them. A formal penalty will be the best solution to this problem.
