Water sanitation hygiene

Considerations for policy development and scaling-up household water treatment and safe storage with communicable disease prevention efforts

World Health Organization


An estimated 780 million people drink water from unimproved sources, and millions more drink contaminated water from improved sources. Unsafe drinking-water, along with inadequate hygiene and sanitation contributes to more than a million deaths each year. While countries work to provide universal access to safe, reliable, piped-in water, WHO and UNICEF have called for targeted, interim approaches that will accelerate the heath gains associated with safe drinking-water for those whose water supplies are unsafe. One such approach is household water treatment and safe storage (HWTS) to prevent contamination during collection, transport, and use in the home.

This document serves to share key outcomes from discussion amoung the HWTS community. It begins by summarizing the main discussion outcomes, including the specific recommendations for integrating HWTS with key health efforts and supporting scaling-up efforts. It then provides a brief description of the presentations and discussions.
