Rainwater harvesting made mandatory for all buildings
· Chennai
After severe drought, a 2003 ordinance required every building in Tamil Nadu to install rainwater harvesting structures by 31 August.
Following the drought years of 2001 to 2003, the Jayalalithaa government issued an ordinance in 2003 requiring all buildings in Tamil Nadu, public and private, to install rainwater harvesting structures. Owners were given about two months, with a deadline of 31 August 2003. The state had begun promoting rainwater harvesting in 2001 and is described as the first Indian state to make it compulsory. Later audits found that many buildings, including government ones, did not maintain the structures.
