HWTS - Filtration

Household water treatment and safe storage (HWTS) has emerged as a viable solution for small and large populations, especially in rural areas. HWTS interventions can lead to dramatic improvements in drinking water quality and reductions in diarrhoeal disease, making an immediate difference to the lives of those who rely on water from polluted rivers, lakes and, in some cases, unsafe wells or piped water supplies.
