Is rooftop rainwater harvesting compulsory in Tamil Nadu?
Yes. Tamil Nadu made rainwater harvesting structures compulsory for buildings in 2003, and approval authorities expect them on new building plans. Check your local body's current requirement when you apply for approval.
Why is rain water harvesting mandatory?
Groundwater in Chennai and its suburbs is heavily drawn down, and coastal aquifers face seawater intrusion. Recharging rooftop water restores wells and borewells and reduces street flooding during the monsoon.
