Who We Are

The Puget Sound Clean Water Alliance (PSCWA) provides a collective voice for clean water agencies in the region that are dedicated to the effective stewardship of a healthy, vibrant Puget Sound.

What We Do

We analyze peer-reviewed, scientific, environmental, and economic data and use it to develop regional strategies aimed at protecting and enhancing Puget Sound.


We strive to maintain and improve water quality through solutions based on sound, peer-reviewed science. We believe that a watershed approach using adaptive management practices is essential to the long-term protection of Puget Sound.
