Rainwater recharge from large school roof.

Rooftop Rainwater harvesting in a school with very large roof, needs thoughtful solution to effectively and economically implement rainwater harvesting project.  NeeRain has implemented one such solution in a School in the state of Gujarat. The School has traditional roof built with a slop and having free flow of rainwater to the surface and further towards the road. Team NeeRain has undertaken extensive study of the premise to understand the geographical limitations.  The site is a primary school premise, hence they don’t want to implement a project where the large infrastructural changes are required.  Upon the study and observations, Team NeeRain could work out simple design and a implementable solution to capture rainwater from the entire roof, filter the impurities from NeeRainEco filters and divert clean, fresh water to one header pipe, that can lead water up to the dedicated Recharge Borewell constructed in one corner of the school.
