What & Why

Seattle Public Utilities (SPU) recently purchased property at 4500 W Marginal Way SW for use as a new Drainage and Wastewater South Operations Center (SOC). SPU’s current facilities are no longer adequate to house essential field crews, vehicles and equipment that clean and repair the City’s sewer and drainage systems, investigate waterway pollution, provide emergency response to storm events and natural disasters, and more. The new facility will allow SPU to continue providing efficient and equitable utility services for residents in West and South Seattle.

What’s happening now?

SPU purchased the property in 2017 and is currently in the Design Development phase.

Latest updates:

  • In partnership with the Office of Arts and Culture and representatives from the community, the Seattle Arts Commission has selected an artist to develop a vision for permanent public art be displayed on-site.
  • We are reaching out to nearby neighbors as the project progresses to build awareness of the new facility and ensure we are being responsive to community needs and questions.

Project goals and benefits

SPU needs this new facility so we can continue to provide efficient and forward-looking utility services that keep Seattle the best place to live.
