In northern Ghana, groundwater pollution and waterborne diseases remain major challenges. In the community of Sheshegu near Tamale, residents once relied on well water that had to be boiled before drinking. A project by Dutch company Element15 is changing that with the help of borehole filtration systems that remove sediments and bacteria. Laboratory tests found unfiltered water exceeded WHO limits for E. coli and coliform bacteria, while filtered water met recommended standards. Since 2024, the initiative has installed 65 filtered water systems, providing nearly one million people with access to safe drinking water. The project also creates local jobs, reduces firewood use and deforestation, and has helped cut more than 29,000 metric tons of CO2 emissions. By combining clean water access with community maintenance and carbon-credit financing, the initiative aims to deliver a sustainable solution for rural communities.
