Safe water supplies also depend on sanitation and the practice of good hygiene. Water quality then needs to be monitored and sustained. UNICEF’s activities are designed to give the population a safe, adequate and affordable year-round water supply. This means helping communities gain access to geological and engineering skills that can provide a supply of water, maintain it and monitor its quality. Communities and local government structures need to be able to take up national policies and translate them into practical, long-term strategies to ensure that they have, and can sustain, a supply of safe water.
