In Nigeria, access to piped water is limited, with only 11.7% having access and even fewer (3.5%) having it within their homes. Also in Kenya, only 36.8% have access to piped water and 22.8% have it within their homes. Due to the low distribution and availability of piped water to provide clean drinking water, many households in Nigeria and Kenya still have to boil water before drinking.

As a large fraction of households use solid fuel such as firewood and coal for cooking in Nigeria (80.6%) and Kenya (69.2%), the need to boil water before drinking causes vast greenhouse gas emissions. Furthermore, due to solid biomass use for cooking and boiling, households in both countries suffer from indoor air pollution leading to health issues, particularly among women and children.

The project aims to reduce non-renewable fuel consumption from boiling water by introducing and maintaining water purification systems primarily in public schools to reduce GHG emissions and lower indoor air pollution, benefiting health and the environment. So far, the project has managed to provide water purification systems to 40,000 schools in Nigeria and Kenya providing clean water to 16 million students and teachers.
