Rainwater Harvesting

Rainwater harvesting (RWH) is a simple method by which rainfall is collected for future usage. The collected rainwater may be stored, utilised in different ways or directly used for recharge purposes. 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. Though the term seems to have picked up greater visibility in the last few years, it was, and is even today, a traditional practice followed in rural India. Some ancient rainwater harvesting methods followed in India include madakas, ahar pynes, surangas, taankas and many more.

This water conservation method can be easily practiced in individual homes, apartments, parks, offices and temples too, across the world. Farmers have recharged their dry borewells, created water banks in drought areas, greened their farms, increased sustainability of their water resources and even created a river. Technical know how for the rooftop RWH with direct storage can be availed for better implementation. RWH An effective method in water scarce times, it is also an easily doable practice. Practical advice is available in books written by Indukanth Ragade & Shree Padre, talks by Anupam Mishra and other easy to follow fun ways

Hello,

We are a housing society in Mumbai. We have obtained permission for borewell and drilled the borewell and have dug the ringwell pit around the borewell. So this will be for borewell recharge. We have dug another ringwell, this will be for groundwater recharge. We want to know if any permission from BMC is required for ringwell. Since, ringwells are ready, can we apply to BMC for confirmation or there is no need? Can BMC take any steps against managing committee for these ringwells? Please guide, our intention is good but we don't want hassles.

Thanks Rajesh

Our apartment complex in Bengaluru has sloping roof which does not allow us to have a roof top collection of rainwater. All that water comes down and flows on the roads of the complex to the lowest point in our complex before it goes out. Can this water which has traversed the complex on ground level be used to recharge the borewell directly using just layers of differently sized gravel and sand or more sophisticated filtering will be required to remove cleaning chemicals and fertilisers (used in gardens) before it can recharge the borewell ?
