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.
What goes inside a recharge pit?
Layers of stone and sand: larger stone such as 40 mm jalli at the bottom, 20 mm in the middle and coarse sand on top as the filter, under a removable cover. The sand layer traps silt and needs cleaning before each monsoon.
