Beyond harvesting, complete water security — from the rooftop to a safe tap to groundwater recharge.
Rain to Tap is our answer to the national water crisis. Rainwater harvesting usually stops at collecting the rain. We take it all the way: from the rooftop, through a series of nature-inspired filtration stages, to a safe tap that people can use every day — while the surplus recharges the groundwater beneath.
That is why we call it Rain to Tap, not just rainwater harvesting. We began in government schools — providing safe water for daily use and groundwater recharge at the same time. Relief today, while securing tomorrow.
Millions of school children lack access to safe drinking water every day, affecting attendance, health and learning outcomes.
Groundwater levels are falling across Karnataka and Maharashtra as urban growth and agriculture drain aquifers faster than rain can recharge them.
India receives enough rainfall to solve its water problem — but without infrastructure to capture, filter and store it, most of it is lost.
Seven filtration stages take rainwater from the rooftop to a safe, drinkable tap — with the overflow recharging the groundwater below.
The first stage catches leaves, twigs and large debris from the rooftop before water enters the system.
The initial, most contaminated runoff from the roof is diverted away automatically, so only cleaner water continues through the system.
A nature-inspired filtration layer removes fine particulates and improves water clarity before the sump.
The sump stores filtered rainwater and can also accept municipal and other water sources — making the system resilient year-round, not just in monsoon.
Settled silt and fine sediment are removed before overflow water moves to the recharge infrastructure.
Overflow water percolates slowly through a gravel-and-sand pit, recharging the soil layer above the aquifer.
The final overflow feeds directly into the local borewell, raising groundwater levels for the entire community — not just the school.
Multiple natural filtration stages working in sequence — removing debris, particulates and silt before the tap.
Gravity-fed throughout. No pump, no power bill, no breakdown risk — the system runs itself.
Safe drinking water from the tap today, and rising groundwater for the community tomorrow — two outcomes in one system.
