Metrowater identified some 45 water stagnating areas in Besant Nagar in the stretch of Alcot Kuppam to Odai kuppam, 14 locations on Kamarajar Salai and 4 locations in Chintadripet for implementing RWH structures. In the rainwater stagnated at the rains.

As the stagnant rainwater can be recharged into the ground, suitable RWH structures were installed to these locations as a measure of flood mitigation.

The newly constructed storm water drains provided with percolation pits for recharging the underground aquifers.

Storm water drains can be connected to nearby open wells/recharge pits and in nearby parks.
