The focus of the study is on the impact of the programmes at the level of the end beneficiaries. Main effect variables taken up in the impact analysis are quality and quantity of the drinking water that is supplied and consumed, the actual use of improved water sources and sanitation facilities, hygiene behaviour, the time burden of water collection, the use of time savings for schooling and/or economic activities, the health effects and costs, and the financial viability of the investment and fee structure. The study also addresses differences in benefits across socio-economic groups, and differences between the dry and rainy season. The study has been designed with the explicit aim of providing quantitative evidence on the effects that can be attributed to the interventions by comparing changes over time and between households with (treatment) and without (control) programme interventions. The interventions studied are water supply infrastructure (manual pumps and small piped systems), public latrine buildings and hygiene promotion.
