Ballard siphon project to continue work next week

Puget Sound Energy (PSE) will continue work on the Ballard siphon replacement project next week, focusing on the southern end on West Commodore Way near 24th Ave W. The siphon replacement project has been ongoing since last fall. PSE is working to replace a pair of 75-year-old sewer pipes that run under Salmon Bay. The old wooden pipes convey about 60-million gallons of sewage to the West Point Treatment Plant near Discovery Park every day and are at the end of their lifespan.

Next week, starting Monday March 19, PSE will be relocating utilities in preparation for installation of a junction structure connecting the new siphon to the existing conveyance system. The work is anticipated to be completed by Friday, March 23.

PSE says traffic will be temporarily reduced to one lane on West Commodore Way and 24th Avenue West during this work and there will be some temporary parking restrictions.

What to expect at the South Site:

  • Periodic traffic revisions on West Commodore Way near the 24th Avenue West intersection
  • High levels of activity involving crews, cranes, excavation equipment and trucks
  • Increased truck traffic on and around West Commodore Way
  • Possible work on Saturdays and/or longer work hours during the week

Work hours will be from 7 a.m. to 6 p.m. on weekdays.
