Rainwater Harvesting

Rainwater harvesting (RWH) is a simple method by which rainfall is collected for future usage.

With depleting groundwater levels and fluctuating climate conditions, RWH can go a long way to help mitigate these effects. Capturing the rainwater can help recharge local aquifers, reduce urban flooding and most importantly ensure water availability in water-scarce zones.
