Water Supply, Sanitation, and Hygiene

Authors: Guy Hutton, Claire Chase

Safe drinking water, sanitation, and hygiene (WASH) are fundamental to improving standards of living for people. The improved standards made possible by WASH include, among others, better physical health, protection of the environment, better educational outcomes, convenience time savings, assurance of lives lived with dignity, and equal treatment for both men and women. Poor and vulnerable populations have lower access to improved WASH services and have poorer associated behaviors. Improved WASH is therefore central to reducing poverty, promoting equality, and supporting socioeconomic development.
