why we’re invested

Efforts by water authorities, non-profits, and governmental agencies to address unsafe water and poor sanitation are held back, not by a lack of data, but by how hard it is to find and use.

The Challenge

The data exist. Project W makes it usable.

Despite the ambitions of the United Nations Sustainable Development Goals, billions of people still do not have safe drinking water and sanitation facilities. Closing this gap requires faster progress and smarter use of resources.

WASH investments should be guided by evidence, but critical data is often fragmented across platforms or underutilized.

Project W brings this data together, making it easier to find, interpret, and act on, so that programs reach more people and resources go further.
