3:25 PM: Thanks for sending the tips and photo. A crew is working along the Lincoln Park beachfront trail, with signage warning that the problem involves “raw sewage.” We have inquiries out to try to find out what happened.
4:34 PM: Seattle Public Utilities spokesperson Sabrina Register tells WSB it’s a King Cpunty Wastewater Treatment issue – SPU “responded to the overflow earlier today and checked all of our assets in and around pump station 42, and crews did not find any issues. We are working with our County partners as they take over the response and regulatory reporting.” So now we’re checking with KCWTD.
6:30 PM: We talked briefly with KCWTD spokesperson Marie Fiore, who said the problem was with the Barton Pump Station (north of the ferry dock) but she was still awaiting more information on what exactly had happened.
10:08 PM: No additional major details but KCWTD just sent a statement:
King County Wastewater Treatment Division workers quickly responded to a combined sewer leak on Sunday afternoon. Seattle Public Utilities, who had initially responded to the issue, alerted county staff. The leak caused a combination of stormwater and wastewater to enter the beach at Lincoln Park, along a public trail.
A King County wastewater crew responding to the incident was able to locate the breach in the line and begin temporary repairs to stop the leak. Crews also began cleanup efforts and will post additional caution/closure signs.
King County reported the overflow to health and regulatory agencies and will begin water quality testing near Lincoln Park Beach and the Barton Pump Station. The beach is expected to be closed until several days of water testing confirm the water is safe.
