CDC at Work: Global Water, Sanitation and Hygiene (WASH)

Inadequate water, sanitation, and hygiene (WASH) conditions exist in a range of settings, from temporary refugee camps to permanent homes in large cities.

CDC’s global WASH program provides expertise and interventions aimed at saving lives and reducing illness by improving global access to healthy and safe water, adequate sanitation, and improved hygiene. The WASH program works on long-term prevention and control measures for improving health, reducing poverty, and improving socio-economic development as well as responding to global emergencies and outbreaks of life-threatening illnesses. These improvements reduce the lethal impact of WASH-related diseases ranging from cholera to typhoid fever to hepatitis.

CDC’s global WASH work is focused in six areas and involves partnerships with other US government agencies, Ministries of Health, non-governmental agencies, and various international agencies.

Making Water Safe to Drink and Use


Promoting safe water through CDC’s Safe Water System (SWS), which allows individuals, health workers, and schoolteachers to treat and safely store water in homes, health facilities, and schools, and Water Safety Plans (WSPs), which identify water quality threats in community water systems and water utilities, while implementing solutions to those threats.
