Water purification with Solar WADI devices in India

This project provides a verified carbon credit that can be retired on purchase.

Project WADI distributes solar water distillation devices (WADIs) to families in Madhya Pradesh, India, providing access to safe drinking water and reducing reliance on boiling water for purification, thereby cutting CO2 emissions and deforestation. WADI is a solar-powered UV measurement device. It indicates when contaminated water in PET bottles has been disinfected by the sun's UV radiation and is safe to drink. WADI is a low-tech, sustainable solution empowering communities to purify their water without the need for fuel.

By providing access to safe drinking water the project ensures a reduction of waterborne diseases leading to reduced health costs for families and fewer sick days- school attendance increases up to 40% and working days up to 60%. Moreover, by distributing WADI technology to households the C02 emissions of each family are drastically reduced and the deforestation of important forests is prevented as the water no longer has to be boiled with firewood.
