Water Filtration: Keep it Clean - The Washing Machine Project
THE CHALLENGE: Create a filtration solution that allows wastewater from a Divya wash cycle to be collected and reused for washing, cooking, cleaning, or agricultural farming.
Imagine spending 20 hours a week on the backbreaking task of handwashing clothes because you don’t have access to an electric washing machine. That’s the reality for 70% of the world’s population – walking long distances to wash their clothes in rivers, and carrying buckets to bring water to their communities as an alternative.
Inspirational British Engineer Nav Sawhney witnessed this first-hand on a sabbatical in South India in 2018, motivating him to set up The Washing Machine Project (TWMP). He recognised that the time spent handwashing clothes created a significant barrier to education for low-income and displaced people worldwide, as well as causing physical hardship through the onset of chronic joint and back pain.
This experience inspired Nav to develop a prototype for an affordable off-grid manual crank washing machine – The Divya. Unique in its application for humanitarian purposes, it requires no electricity to operate. Designed to be sustainable with its use of recyclable off-the-shelf components, it’s easy to set up, maintain, and be operated anywhere – by anyone.
And the results achieved with its use? Time spent handwashing is reduced by 75%, with 50% less water required!
In an ideal world…
We would have a filtration system connected to the Divya washing machine that collects the used polluted water after each wash cycle to prevent it from re-entering local water sources.
This wastewater could then be filtered so that we can maximize its reuse for washing, cooking, cleaning, or agricultural farming. Filtering the waste to reinforce life.
