TuriTap is a passive chlorine doser adapted for handpumps, bringing safe water to rural communities without electricity or behaviour change. Using the Venturi effect, it meters liquid chlorine as water flows, disinfecting at the source and providing residual protection. Because handpumps produce irregular, pulsed flow, the new handpump attachment stabilises dosing to keep concentrations consistent. Field trials show treated water meets WHO residual-chlorine guidelines. Low cost and scalable, TuriTap helps prevent waterborne illness while fitting existing collection routines
