About Grand Water Saving Challenge:

In support of the Indian Prime Minister's Swachh Bharat (SBM) mission and the United Nations SDGs, Hindustan Unilever Ltd. (HUL), in association with Invest India, Startup India and AGNIi, launched the Grand Water Saving Challenge. Managed by the Toilet Board Coalition (TBC), the challenge aims to address the need for an efficient flushing system in public toilets to ensure optimal water use while ensuring clean and hygienic toilets.

The Grand Water Saving Challenge is a national hackathon inviting technologists, inventors and start-ups in the water and sanitation field to participate. The winners of the challenge will receive a cash prize of Rs. 5 Lakh in addition to the opportunity to install and test the invention at a Suvidha center, developed by HUL.

Problem Statement:

An innovative water saving flush system designed for squat latrines to ensure clean and hygienic toilets for all

Community and public toilets remain one of the most challenging shared spaces in terms of cleanliness, hygiene, and operations and maintenance. Water supply to these is often limited and the burden of wastewater and fecal sludge management & treatment is high as well. There is a need for a better flush system that uses less water while ensuring a clean and hygienic toilet.

The participants of this challenge need to design (stage 1) and prototype (stage2) a flush system on a squat toilet pan (can be made from ceramic or recycled plastic) that uses no more than 2.5 liters of water to clean the pan surface of any visible fecal residues evaluated using actual or simulated human feces
