Wastewater Treatment repairs leak at Interbay pump station

Summary

King County Wastewater Treatment Division workers repaired a leak at the Interbay pump station which did not reach any body of water.

Story

A slow leak at Interbay pump station (located near the intersection of West Garfield Street and 15th Avenue West in Seattle), was discover on Thursday, Feb. 11 and repaired by the following day. Wastewater operations were not interrupted. The pump is expected to be back online by the end of Friday, Feb. 12.

The leak, similar in flow to a trickling garden hose, created puddles in the gravel near the force main pipe. While most of the spill was surface-level at the pump station, a small amount reached the public right-of-way. By early morning, vacuum trucks had eliminated the surface water, cleaned the area, and excavated the dirt and gravel surrounding the force main. Water testing at nearby Smith Cove confirmed wastewater did not reach any body of water.

The Washington Department of Ecology and Public Health – Seattle & King County have been notified.
