Alki standby generator

Enhancing the Alki Wet Weather Treatment Station and 63rd Ave Pump Station for reliability to protect Puget Sound.

Project description

Installing this new generator brings important public health and environmental benefits to Puget Sound and your neighborhood

  • Provides permanent and reliable power for important wastewater facilities serving West Seattle.
  • Prevents wastewater overflows into Puget Sound and nearby bodies of water.
  • Protects water quality.

Reliable power supply helps ensure our sewer system keeps working during outages and helps protect water quality in Puget Sound

Power outages disrupt operations of the facilities that can result in overflows. The Alki Standby Generator project will provide permanent and reliable electrical power to both the Alki Wet Weather Treatment Station (WWTS) and the 63rd Ave Pump Station. This will help stop stormwater and wastewater from overflowing into nearby neighborhoods and Puget Sound.

During construction, there will be temporary impacts to street parking, sidewalks, pedestrian ramps, and driveway access. Limited beachfront access will be on the eastern side of Charles Richey Sr. Viewpoint. We will work with the community to limit these disruptions and will share information about any impacts before they occur.

We will restore all work areas according to the City’s requirements and standards once construction is complete. This will include improved pedestrian ramps at the intersection of Beach Dr SW and 64th Ave SW.

Connecting the generator from the Alki WWTS to the pump station will require less equipment at the pump station. This means smaller changes to the footprint and visual impacts from the road.
