The Chennai Metropolitan Water Supply and Sewerage Board kick-started the
rainwater harvesting from abandoned quarries in Kancheepuram district, and the
collected storm water will be drained into Chembarambakkam water treatment
plant to enhance the drinking water supply to greater Chennai.
As the quarry level reached its maximum level, the board proposed to convert
30 mld of rainwater stored in the quarry for drinking water purpose by treating
the same at Chembarambakkam treatment plant. The capacity of Chembarambakkam treatment plant is 530 mld of which 235
mld drinking water is supplied to residential areas in the city. By converting the
quarry water into drinking water for residential areas, one MCFT of
Chembarambakkam lake level will be saved.
