Why We Call It Rain to Tap

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.

India's Water Crisis, School by School

🚱

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.

How It Works

Seven filtration stages take rainwater from the rooftop to a safe, drinkable tap — with the overflow recharging the groundwater below.

01

Leaf Filter

The first stage catches leaves, twigs and large debris from the rooftop before water enters the system.

02

First Flush Device

The initial, most contaminated runoff from the roof is diverted away automatically, so only cleaner water continues through the system.

03

Ferro Filter

A nature-inspired filtration layer removes fine particulates and improves water clarity before the sump.

04

Multi-Use 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.

05

Silt Trap

Settled silt and fine sediment are removed before overflow water moves to the recharge infrastructure.

06

Recharge Pit

Overflow water percolates slowly through a gravel-and-sand pit, recharging the soil layer above the aquifer.

07

Borewell Recharge

The final overflow feeds directly into the local borewell, raising groundwater levels for the entire community — not just the school.

What Makes It Superior

6-Level Filtration

Multiple natural filtration stages working in sequence — removing debris, particulates and silt before the tap.

Zero Electricity

Gravity-fed throughout. No pump, no power bill, no breakdown risk — the system runs itself.

Dual Water Security

Safe drinking water from the tap today, and rising groundwater for the community tomorrow — two outcomes in one system.

Data-Driven Impact

Verifiable litres saved and recharged per site, with certified utilisation certificates and ESG progress reports for partners.

School-First Design

Built for government schools — robust, low-maintenance, safe for daily student use, with community access built in.

120+ Schools Done. Goal: 1,000+ by 2030.

Every school we complete gives students safe water and recharges the groundwater for the whole community.

Government Schools Across Karnataka & Pune

Karnataka

Government schools across Bengaluru and surrounding districts, with installations dating back to our earliest pilot sites.

Pune

Expanding into Maharashtra's government schools, where water scarcity and groundwater depletion are acutely felt.

Expanding

With CSR partner support, we are identifying the next 100 schools. Get in touch to nominate a school in your region.

📍 A school-level map with pinned installations, filters by district and year, and a sponsor attribution will be added here — TFF to supply the school list as a spreadsheet.

Fund a School. See the Proof.

Choose your priority — Water, Solar or Tree Plantation — and tell us your preferred region. We will send a customised proposal with a transparent line-item budget and verifiable metrics.

Every installation comes with a utilisation certificate, site photographs and an ESG progress report for your CSR team.
