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. 

To decide which household water technology is most appropriate for your needs, financials, and preferences, click the '''Community Choices''' tool in the upper right of this page, to help you pick the best one! This tool has been brought to you by [http://www.pacinst.org/ The Pacific Institute].
