Water is essential for survival, yet millions of people in Uganda still face illness from contaminated sources. Children are especially vulnerable. We follow efforts to secure safe drinking water—from well diggers searching deep underground to engineers tackling dangerous levels of iron in school borehole water. Then there’s the growing pollution in Lake Victoria, a source of water for millions. Algae and wastewater threaten the lake, which is one of Africa’s most critical freshwater ecosystems. Innovative filtration and wastewater recycling systems show how practical solutions can protect communities, reduce disease, and support a sustainable water future.
