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.

Rainmax filter

Rainmax’s filter is the most effective, affordable and easy-to-use solution for Rooftop Rainwater Harvesting. It carries out a two-stage filtration process through its fine 100 micron Stainless Steel (SS) 304 grade mesh and its unique first flush system, thus effectively removing dust, leaves, contaminants and other debris. Depending on your roof area and requirements, there are 4 variants of this filter.

If you are trying to solve water problems for a residential township, gated community or large apartment building, the Rainmax Injection Well System is the most beneficial and cost-effective solution for you. It ensures constant supply of groundwater without having to depend on water tankers.


What customers say?

Shekhar Sai Lakshmi Arcade, KPHB, Hyderabad

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.

Rajesh Gautami Enclave, Kondapur, Hyderabad

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!

Niranjan Designation

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.

Angad Home Owner,
Ludhiana, Punjab

Two years back built a house, only to discover that our area had severe water shortages and dry borewells due to poor groundwater scenario. But after setting up a rainwater harvesting system using Rainmax, our underground tank is full! We expect that in a short time our borewell will be recharged too.

Smart design, and good quality product. Easy to use also, and was installed very easily also. This is what I was looking. It is sad that more people don’t harvest rainwater and let all that water go to waste. It is such a simple process.

Shreya Facilities Manager,
Aman Hotels, New Delhi

Hotels and commercial complexes enjoy uninterrupted supply of municipal water at a high cost. Our management team made the smart decision to install a Rainmax Rainwater harvesting system, which helps us supplement our original water supply. We treat this water and use in our gardening, laundry and cooling systems. Overall water costs have substantially reduced.

Rukmini Home Owner,
Miyapur, Hyderabad

Overall cost of installing system is a little high – cost of filter is only small part of it. But the cost is recovered in short time. Smart decision to harvest rainwater in these times.
