 The Ballard Pump Station design is complete!

The Ballard Pump Station has reached 100% design, which means we’re ready to advertise for bids, hire a contractor, and then start construction in 2023! The Ballard Pump Station is an extremely important element of the Ship Canal Water Quality Project. The storage tunnel that MudHoney, our 18-ft diameter tunnel boring machine, is currently digging is designed so that sewage and stormwater in the tunnel runs at a slightly downhill grade from Wallingford to Ballard. The Ballard Pump Station will pump flows from the tunnel to West Point Treatment Plant for treatment. You can find out more about how the tunnel, pump station, and treatment plant work together to create a healthier Ship Canal and Puget Sound in our project overview factsheet.
The pump station building will be an 80-ft tall, illuminated tower inspired by Ballard's shipyards and maritime industry, and will be surrounded by a maintenance yard and tree nursery. In coordination with Seattle Department of Transportation (SDOT), trees from the nursery will be used throughout the city as street trees. The site includes artwork by Jeffrey Veregge, from the Port Gamble S’Klallam Tribe, that celebrates the Coast Salish heritage and historical use of the area. The 24th Ave NW right-of-way includes green stormwater infrastructure, improved parking, pedestrian access, and street end. Check out this video and this Flickr album to learn more! Also be sure to check out our Flickr albums for images from recent construction and our new tunnel.

Eleanor Jackson is the Design Manager for the Ship Canal Water Quality Project. She is responsible for ensuring that the project meets its design requirements by managing City staff and consultants and making sure all pieces of this $570 million project are well-designed investments for our planet and City. SPU’s latest blog post highlights her history at SPU, how she got into engineering in the first place, and her favorite parts of the work. Thanks for all your hard work, Eleanor!
Ballard & MudHoney
MudHoney continues to tunnel toward Wallingford. During tunneling activities, you should anticipate:
- Truck deliveries of concrete segments and MudHoney equipment
- Nighttime segment deliveries and tunnel spoils being hauled off
- Noise and vibrations typical of a construction site
Crews are working 24 hours a day, six days a week and will continue until MudHoney reaches Wallingford by early 2023. Sunday work may also occur.
Ground monitoring is ongoing along the tunnel alignment and is done from both inside MudHoney and on the surface.
East Ballard
Excavation is complete for the underground mechanical and electrical vault on NW 45th St. Construction of the reinforced concrete structure will begin soon.
You should anticipate:
- Starting as soon as June, one-lane closure on 11th Ave NW through November 2022. Flaggers will direct northbound and southbound traffic, and additional directional signage will be in place.
- Heavy equipment in the area
- NW 45th St closed to traffic; vehicles must detour onto NW 46th St
- Burke-Gilman Trail users remain detoured to the north side of NW 45th St
- Flaggers will help direct traffic during daytime working hours. Please follow all detour guidance on site. For safety, bicyclists should either dismount or cross train tracks at a 90-degree angle. Please use extra caution in wet weather as ramps may be slippery.
- Noise and vibrations typical of a construction site
Regular work hours will be Monday through Friday, from 7 am to 5 pm. Night and weekend work may occur.
Fremont
Lane reductions on Leary Way NW, between 1st Ave NW and NW 39th St, will be in place through mid-May so crews can conduct utility work on Leary Way NW. Crews will also be working on large eight-foot conveyance tunnel pipes inside the white tents from 7 am to 10 pm on weekdays, and possibly 9 am to 10 pm on weekends, over the next few months.
During this time, you should anticipate:
- Dust and grinding noise
- Lane reductions on Leary Way NW
- Excavators working on-site for utility installation work
- Truck traffic on Leary Way NW as trucks bring and remove materials to and from the site
- NW 36th St between Leary Way NW and 3rd Ave NW closed (through the remainder of the project)
- Pedestrian detours on Leary Way NW; please follow all detour guidance on site
- Generators running during work hours to power equipment
- 2nd Ave NW, between Leary Way NW and NW Canal St, closed to vehicle and pedestrian traffic for sewer and diversion structure work at least through the end of 2022
- NW Canal St open to two-way traffic to allow access during this closure. Please do not park at the west end of NW Canal St so two-way traffic may turn around at the closure.
- Noise and vibrations typical of a construction site
Regular work hours will be Monday through Friday, from 7 am to 5 pm. Work inside the tents may occur during nights and weekends as described above.
Wallingford
Work is resuming at the Wallingford shaft site this week. A large concrete pour is scheduled for Friday, April 29, starting early and lasting all day. On this day, there will be parking restrictions along the streets adjacent to the site.
During this time, you should anticipate:
- Concrete trucks coming in and out of the site
- Noise and vibrations typical of a construction site
Regular work hours will be Monday through Friday, from 7 am to 5 pm.
Queen Anne
Construction of underground vaults is ongoing through the summer. This work will require a slight adjustment to the Ship Canal Trail detour starting later this spring.
During this time, you should anticipate:
- Trucks coming in and out of the site
- Noise and vibrations typical of a construction site
- The West Ewing Mini Park parking lot to remain closed through mid-2023
- A localized Ship Canal Trail detour at least through summer 2023 (see map). The trail will be adjusted north later this year for construction of the third below-grade vault. Details and schedule for intermittent changes to come.
Regular work hours will be Monday through Friday, from 7 am to 5 pm. Night and weekend work may occur.
