Automatic Chlorination and Child Health in Urban Bangladesh

Trial ID or NCT#

Municipal water networks within industrialized countries typically rely on centralized treatment to manage piped water quality. Optimal water quality at the tap, however, requires well-maintained piped distribution networks, and performs best when piped systems are fully pressurized. In low-income cities such as Dhaka, water distribution networks are inadequately maintained and typically supply intermittent service; as such, they are vulnerable to recontamination during negative pressure events. Among populations accessing these types of improved water sources in urban settings (e.g. shared taps), it is unknown if consistent treatment to provide chlorinated water at the point of collection would have a significant health benefit. Furthermore, almost all previous studies of water treatment interventions in low-income countries have been unblinded with self-reported diarrhea as the main outcome, casting doubt that reported impacts of water disinfection on diarrhea are not due entirely to social desirability bias. Stanford University in collaboration with icddr,b will conduct a randomized evaluation to assess the impact on access to automatically chlorinated water on water quality and child health.
