Evaluations should be designed to answer “why not” if impacts do not occur as expected. The evaluation leaves some questions unanswered, such as “why is there still water contamination at the household?” and “why are households not using their saved time for income-producing activities?” Qualitative research methods should be used for future evaluations to try to answer these questions in order to provide more learning for MCC, our partner countries, and other investors in the sector.
