About the target

Irrisol Engineering Limited (Irrisol) is a Ugandan social enterprise specialising in solar-powered water infrastructure and irrigation systems for rural and peri-urban communities. Founded in 2017 by water and irrigation engineer Joash Bwambale and headquartered in Kasese Municipality, Western Uganda, the company designs, constructs, and operates two complementary product lines: community-level water mini-grids that deliver piped water through solar pumps and gravity-fed schemes, and standalone solar-powered water systems installed on contract for schools, hospitals, businesses, and households. Revenue is collected via consumption-based billing and mobile-money payments, with seasonal payment plans aligned to smallholder farmers' income cycles.
