How it works

A matka, inside a matka.

We didn't invent a device. One pot rests inside another; water goes in the top, gravity pulls it down through the treatment layers, and clean water collects in the inner pot — ready to drink.

01

Cloth + copper

The first stage screens out visible dirt and adds a natural antimicrobial effect — copper has been used to store and clean drinking water in India for centuries.

02

Rice husk ash core

The heart of the system. Rice husk ash is an agricultural waste product, rich in silica, and a proven adsorbent that pulls dissolved metals and fluoride out of the water.

03

Washed tea waste

Spent tea leaves — another waste stream put to work — capture additional heavy metals and dyes as the water passes through.

04

Muslin polish

A fine muslin layer at the base, so the water reaching the inner pot is clear and clean. No pump, no motor, no moving parts — nothing to break.

The exact way each layer is prepared is what makes Jal Setu work as well as it does — that part we keep in-house. And the form matters as much as the science: a fancy purifier that feels foreign gets left in a corner. The matka is already trusted, already cools the water, already part of the home. Familiarity isn't a bonus feature. It's the reason Jal Setu actually gets used.
