This study uses longitudinal life-history data to examine factors affecting child survival in Ouagadougou, the capital city of Burkina Faso. It focuses especially on the controversial role of improvements in water supply on infant and child mortality. In event-history models (piecewise exponential models), as expected, mother’s education is strongly associated with lower child mortality risk and captures most of the effect of water supply. The failure to discover a positive effect of the availability of piped water on childhood mortality may be caused by inadequate modeling of the effect (too partial) or inadequate measurement of access to clean water in and of itself – that is, inadequate conceptualization of how access to water affects health. Relations to water management within the household and water-related hygienic practices are discussed.
