Interventions resulting in public infrastructure changes were found to be less effective than household-based interventions; however, both are important aspects of improved health outcomes for women (128, 130). Public water infrastructure requires regular maintenance and periodic replacement and water from these sources is often contaminated (130). However, even public water points that provide good-quality water have had minimal impacts on health outcomes (136). One review estimated that water-source interventions were associated with a 27% reduction in diarrhea risk at all ages, whereas household-based interventions were associated with a 43% reduction (128). This could be associated with bias and confounding, as measuring WASH outcomes is not a blinded process (128). The differential impact could also be related to practice. As compared with public water sources, home water connections were associated with greater odds of handwashing and fecal waste disposal (136). As a significant portion of diarrheal disease is a result of person-to-person transmission and poor hygiene, interventions that improve domestic hygiene behaviors can have a significant impact (136). Behavior change communication and resource provision, e.g., soap and point-of-use water treatment resources, were also important and sustainable aspects of WASH interventions (131, 137).
