Uneven Rainwater Harvesting Structure Coverage in Private Buildings

Despite government mandates making rainwater harvesting structures (RWH) compulsory for all new buildings, a significant portion of older private buildings across Tamil Nadu still lack functioning RWH systems. Poor enforcement and the absence of retrofit incentives mean that groundwater recharge potential is being lost. Strengthening enforcement, offering subsidies for retrofitting, and conducting awareness campaigns can help achieve near-universal RWH coverage.
