July 2018. In Kamuli District, Uganda, a local hand pump mechanic employed by Whave meets with members in a community water committee to discuss their needs and payment for Whave's preventive maintenance services. Whave is a member of the USAID-supported Sustainable WASH Systems Learning Partnership, a consortium of researchers and practitioners identifying solutions to the challenge of developing robust local systems capable of sustaining water, sanitation, and hygiene (WASH) service delivery. As climate change threatens water supplies and infrastructure in sub-saharan Africa, the need for strengthened local systems that provide reliable water services is critical. Community-managed preventive maintenance is one method to avoid hand pump breakdowns and maintain water source functionality.
