May 19, 2017 update

Restoration costs at King County’s West Point Treatment Plant will fall below property insurance policy coverage limits and pose no impact to King County wholesale sewer rates in 2017-18. A cost estimate prepared by engineering firm CH2M, which puts total restoration costs at $49 to $57 million, includes risk allowances related to unknown equipment replacement costs and other factors.

Background

The King County Wastewater Treatment Division is implementing comprehensive restoration actions following a major equipment failure at the West Point Treatment Plant on Feb. 9 that resulted in bypasses of untreated stormwater and wastewater into Puget Sound. Restoration work is ongoing to restore the plant to its full operational capacity as quickly and safely as possible.

King County is committed to keeping people informed as we continue the restoration effort. Progress updates and notices will be available on Web and social media and people can contact us with questions and concerns.
