Impact Evaluation of the USAID IUWASH Tangguh Activity: Baseline Report

The study undertook a mixed-methods, quasi-experimental baseline evaluation that focuses on household water security and city-wide water service resilience in 31 of IUWASH Tangguh’s partner cities and districts across North Sumatra, Banten, West Java, Central Java, East Java, and South Sulawesi. The study found that households in IUWASH Tangguh’s community intervention sites report very few disruptions to the availability of their main sources of water and that households use low-cost piped sources, boreholes, or protected wells to meet the bulk of their water needs. Though household water security is quite strong overall, 72 percent of households fall short of at least one Government of Indonesia standard for water services. Affordability and quality are the most common shortcomings. Based on structured, expert review of strategic planning documents, interviews with utility and local government personnel, and review of secondary data, this report finds that neither utilities nor local governments have strongly institutionalized, evidence-based practices of risk identification, understanding, and mitigation, though they are anecdotally aware of hazards that pose risks to their water services. This report concludes with recommendations for IUWASH Tangguh on how to promote household water security and city-wide water service resilience based on these findings.
