Reduced Flooding

Why harvest rainwater?

Many of urban India’s borewells have gone dry, and our country may soon be classified as a drought zone. An average Indian household now spends more than Rs. 12000 on water tankers every year. Rainwater Harvesting is the obvious solution to this problem. It helps ensure uninterrupted supply of clean water with low hardness, while also recharging groundwater and helping prevent urban flooding.

What customers say?

We are a stand-alone apartment building of 25 flats, and depend on water tankers year around. After implementing rooftop rainwater harvesting, we saved around 75 tankers of water in the monsoon, resulting in monetary savings of Rs. 60,000.

Rooftop rainwater harvesting has been a godsend. Not only have we swiftly recovered our initial investment in the filters and plumbing, we have saved a lot of the money spent on tankers. Water shortages are a thing of the past!

We worked with Sai to incorporate Injection Wells at our 120 unit project - Eeco Valley, Chandanagar - because we were dependent on depleting groundwater & water tankers for supply. Now, Rainmax's Injection Wells have recharged our borewells substantially, with rooftop rainwater. It was so effective that many other apartments in our colony also followed suit.
