What’s happening in Ballard in 2024?
  Design concept for the Ballard Pump Station. This view shows both the pump station design and the planned improvements on the 24th Ave NW street-end.
As we continue work at the Ballard shaft site, we're gearing up for something big later this year. In October, work is planned to begin on the pump station at the current Ballard project site. Its job? To move polluted stormwater and sewage from the storage tunnel to King County’s West Point Treatment Plant.
Around the same time, we’ll start installing a 60-inch diameter conveyance pipeline that's 2,000 feet long. This pipeline will run underground through 24th Ave NW, NW 56th St, to 28th Ave NW. Its job? To move polluted stormwater and sewage from your neighborhood into the completed storage tunnel.
We’ve updated the schedules and fact sheets on the project website. Please visit our project website to get the most up to date information about the Ship Canal Water Quality project in your neighborhood. Check out our Flickr albums for recent construction photos as well.
