Our first initiative in this arena, still very much under development, is a tool called WashOpt. This tool finds mathematically optimal solutions for maximizing the public health impact of a theoretical scenario in which two WASH technologies — centralized treatment plants and point-of-use treatment units — may be deployed. Interesting aspects of this work are the simple, Google Maps-like interface, and the ability to perform planning exercises purely in terms of (theoretical) public-health criteria, rather than economic criteria. This area of Wash4All is expected to grow dramatically during Fall 2012. Check out the tool, and be sure to check back.
