The climb

Safe water is a climb,
not a purchase.

Four things have to be true at the same time. Each rung adds one of them — and every rung below has to keep holding, or the one above it comes down too.

Summit · safe drinking water that lasts

Removes the contaminant Puts it within reach Keeps it running Keeps it trusted

Skip one and you get a failure everybody recognises: a plant that works but nobody funds, or one that is funded but nobody maintains. The summit is not a working plant. It is water that is still safe in year five — and the last rung, the one that decides it, is a habit held by people.

Basecamp 01

Horsethe chemistry

The resin that does the work

Hybrid ion exchange media, invented in the USA, that strips contaminants out of groundwater.

Adds Horse

Three resin families, all made in our own Kolkata facility.

HIX™Iron, and cation resin for OEM supply
HIX-Nano™Arsenic, fluoride, nitrate, hardness
HIX RO™High TDS, 0.1 to 2 m³/hr

Basecamp 02

Harnessthe deployment

The plant that puts it to work

Chemistry in a bucket helps nobody. It has to become something you can walk up to and fill a jug from.

Adds Harness

Engineered to your raw water analysis and delivered ready to install.

Household filtersTabletop units for a single home
Water ATMsCommunity kiosks dispensing by the litre
Piped schemes0.25 to 500 m³/hr

Basecamp 03

Haywho pays for it

The money that keeps it fed

Every plant costs something to run after the ribbon is cut. Where that money comes from decides whether it is still running in year three.

Adds Hay

Capital on our balance sheet, not yours.

Basecamp 04

Habitwho keeps it running

The people who keep water safe

A plant nobody checks is a plant nobody trusts, and a plant nobody trusts is one people quietly stop using. Someone has to test the water, read the result and act on it — week after week.

Adds Habit

That is what a Watergrader does. You test your water, grade it A–F, and level up as you keep it that way.

A pilot, run in the open.

Watergrade is a pilot initiative supported by Ashoka and the Cisco Foundation, built on the idea that a water quality grade should be something anyone can produce, read and act on — not something locked inside a lab report.
