World Health Organization Household Water Treatment and Safe Storage (HWTS) Network

Household water treatment and safe storage (HWTS) is an important public health intervention to improve the quality of drinking-water and reduce diarrhoeal disease, particularly among those who rely on water from unimproved sources, and in some cases, unsafe or unreliable piped water supplies. Further, safe drinking-water is an immediate priority in most emergencies, and HWTS can be an effective emergency response intervention.
