About Us


We are the Westside Water Association (WWA). We provide clean drinking water to over 200 households in our neighborhood.

Our district is on the shore of Colvos Passage, on the northwest side of Vashon Island.

The water sources for WWA are adjacent to Shinglemill Creek. The creek runs north through the center of the island and drains into Puget Sound at Fern Cove. Our water supply includes a spring that enters the creek near our pumphouse, a well that taps a 300 foot-deep aquifer within the canyon, two new wells on the canyon crest, and the stream itself in case of very high demand. All of our water comes from the Shinglemill watershed and is replenished by rain that falls mainly from October through May.
