Pune authority will finalise norms to help societies set up rainwater harvesting system. Special workshops will be conducted in collaboration with NGOs and rainwater harvesting experts. Since every housing society has different kind of requirements, it is necessary to suggest different RWH models to them. According to experts, every 1,000 sq ft of constructed area can harvest 70,000 litres and every acre of open area can harvest 25 lakh litre during the rainy season.
In general, water harvesting is the activity of direct collection of rainwater. The collected rainwater can be stored for direct use or can be recharged into the groundwater. The water can be used for agriculture, gardening, livestock, etc. The harvested water can also be used for drinking water as well after purification is done. It can be collected anywhere, but the quantity of water collected is more for bigger structures.
RWH has been made compulsory for all upcoming residential projects falling under PMC and PCMC. But still, many old housing societies have not implemented RWH system.. I have no idea how many of them do not have RWH, but to educate them about it, the authorities are working on a plan.
Yes Siddharth, the authorities are planning to popularise rainwater harvesting (RWH) system in Pune and Pimpri-Chinchwad housing societies. They will also launch a special program for which a special study is being conducted.
