Community choices is a comprehenssive decision making support system that releases trapped knowledge on WASH technologies and solutions to those who most need this information.

The system also links communities and practitioners to funding and technical agencies who could help address WASH needs at the community level. The System prototype is web-based, consisting of sanitation and drinking water treatment modules. To use this system, the user answers a set of questions to identify their economic, environmental, cost, cultural and geological conditions. Based on these responses, the user is provided with a list of technologies which are ranked by how well it fits with the user’s solution. The user can select any technology from the list, and is provided with an easy-to-understand technical description  about the technology, benefits and drawbacks, technical implementation iformation, and contacts for local resources and technical support for that technology.
