Rainwater Harvesting
Rainwater - the purest form of water available
India blessed with abundant rainfall but often does not have adequate water
Rainwater allowed to flow free (barely 3% retained)
Water indiscriminatingly drawn by bore wells & tankers - not being recharged
Ingress of seawater in coastal areas contaminating underground natural 'aquifers'; Hence, importantly looks at rainwater - a free source of water - differently
Rainwater harvesting - simply the direct collection of rainwater to supplement some of our water needs
Can be stored for direct use or to recharge the groundwater levels
Rainwater can be channelised through a filter bed into an underground storage tank
Can be used for flushing, washing utensils & clothes and even gardening
Rainwater is soft water - save on detergents and softeners
Solution inexpensive - a 20,000 litres tank does cost not more than Rs 2,000 per flat, basically a one time cost - requires very little maintenance
Rainwater can be used to recharge the groundwater, improving the water quality and raising the water table
