'Emergency' at Seattle wastewater plant dumping raw sewage into Puget Sound

KING

King County’s West Point Treatment Plant is no longer in "emergency bypass mode" after experiencing equipment failure early Thursday morning, dumping wastewater and stormwater into Puget Sound.

The plant, located in Discovery Park in Seattle's Magnolia neighborhood, went into equipment failure around 2 a.m. Thursday, during the heavy rainfall and high tides which threatened to flood the whole plant. To prevent flooding that would severely damage equipment, the plant went into "emergency bypass mode."

As a result, untreated wastewater was discharged from the plant, about three-quarters of a mile offshore and 240 feet deep in Puget Sound.

Wastewater flows are now redirected back through the treatment plant and flows going to Puget Sound are disinfected. 

King County has notified health and regulatory agencies and is sampling water quality. They are also posting signs warning people to avoid contact with the water over the next several days as a precaution to protect public health.
