WSD Project. The benefits of the WSD Project are derived from improved health outcomes of the beneficiary population. Recent literature has found that reducing disease burden through water, sanitation, and hygiene interventions require a “transformative” set of interventions that are complementary and comprehensive. Thus, the WSD Project is designed to complement and enhance the impact of other investments in the water and sanitation sector in Timor-Leste, in line with a master plan developed by the Government. The WSD Project will construct a wastewater infrastructure backbone in Dili, which will be expanded upon in the future by other donors and financiers so that the system can function efficiently and at a low cost. Therefore, the full benefits (and thus the ERR) of the Project depend on whether additional investment occurs that builds on the backbone provided through the WSD Project. MCC evaluated a range of plausible scenarios based on the extent to which additional investments leverage Project-funded infrastructure. The estimated ERR for the Project without subsequent investments from other sources (e.g., the Government, other donors, and/or the private sector) is
WSD Project. The evaluation methodology will be an impact evaluation if a comparable control group can be identified. If not, the evaluation methodology will be a performance evaluation. The Evaluation Questions follow: ▪ Was the program implemented according to plan (in terms of quantity and quality of outputs?) ▪ Did the program achieve its targeted outcomes, particularly its stated objective of reducing fecal pathogens in piped and stored water and in groundwater, in the timeframe and magnitude expected? Why or why not? The outcomes related to MCC’s learning agenda include household water and toileting practices, household drinking-water quality, and utility operation. Depending on statistical power and program implementation, MCC may be able to assess the project’s contribution to lowering disease prevalence. ▪ Do the results of the program justify the allocation of resources toward it?
