Methodological lessons and findings from an impact evaluation of a WASH project in Indonesia

Internationally, there is growing emphasis on evaluations that show up impacts of WASH interventions, not only on access but also behaviours. This paper reports on the experiences, findings and lessons from the impact evaluation of the Second Water and Sanitation for Low Income Communities (WSLIC-2) project in Indonesia. The project was carried out by the Indonesian Ministry of Health and technical assistance was financed by AusAid via the World Bank. During the project formulation an impact study was planned using a quasi-experimental design: a before and after study in project villages and matched control villages. This paper reports on the problems of such a design in a field programme and how they were addressed. It also suggests an alternative evaluation set up to address the limitations found.
