Water, Sanitation, Hygiene
According to the Centers for Disease Control, global access to safe water, adequate sanitation, and proper hygiene education can reduce illness and death from disease, leading to improved health, poverty reduction, and socio-economic development. However, many countries are challenged to provide these basic necessities to their populations, leaving people at risk for water, sanitation, and hygiene (WASH)-related diseases. Resources available within this theme offer information on providing access to safe water and appropriate sanitation facilities, and introducing sound hygiene behaviors.

Water for the World: Constructing, Operating and Maintaining Subsurface Absorption Systems
U.S. Agency for International Development
A subsurface absorption system is a trench, series of trenches, field or pit that receives effluent from a septic tank and allows it to soak safely into the ground. This technical note describes each step in constructing an absorption system.Read more
