Unlike a vaccine, solutions to rural unsafe water problems involve community organization, appropriate technology, hygiene, sanitation, transfer of ownership, change in behaviour, and long-term maintenance. And we need a solution for hundreds of thousands of rural communities. The solutions are available today; what was missing was the infrastructure to select, fund, manage, monitor, and share thousands of grassroots, community projects - until PWX.

PWX is scalable - it scales local solutions to the size of the global water problem. A participatory decision-making system that enables knowledge-sharing and collaboration, PWX increases the number of expert resources at very low cost to efficiently, transparently, and effectively manage thousands of projects.
