West Point Treatment Plant restoration update for Tuesday, Feb. 28, 2017

Summary

From electricians to engine mechanics, and cleaning specialists to engineers, dozens of people continue the around-the-clock work to safely restore King County’s West Point Treatment Plant to full wastewater treatment capacity as soon as possible.

Story

At the West Point Treatment Plant, crews working 24 hours a day continue to make solid progress following an equipment failure at the facility earlier in February.

Restoration work continues at the treatment plant, where no emergency bypasses of highly diluted stormwater and wastewater into Puget Sound have occurred since Feb. 16.

The plant has capacity to provide limited wastewater treatment for up to 250 million gallons per day – nearly double the amount needed to treat an average day this time of year, but well below the plant’s designed capacity of 450 million gallons per day.

Progress report for Feb. 28:
There are approximately 60 workers at the treatment plant today, Feb. 28, including 50 people who are dedicated to ongoing restoration work.

Worker safety is the top priority, and crews follow rigorous safety protocols that King County has put in place to ensure safety for employees, contractors and inspectors. Work is being done carefully and methodically.

• Workers have removed about 80 percent of all the various motors that might have been damaged as a result of the equipment failure and subsequent flooding in the plant. Crews are replacing 10 or more motors every day – and they are focusing on repairing or replacing machinery that is on the critical path for restoring full wastewater treatment at West Point.

• Instrumentation inspections and repair are continuing, as are removal and replacement of light fixtures. Temporary lighting has been in place throughout the plant to facilitate recovery work.

• Electrical panel replacement work continues, with contractor teams working on the design and construction of the replacement panel structure.

Upcoming weather:
West Point currently has capacity of providing limited wastewater treatment to roughly 250 million gallons per day. This is nearly twice the capacity needed to safely treat all of the stormwater and wastewater the plant receives on an average day for this time of year.

Rainfall totaling one inch or more over two or three consecutive days in Seattle could lead to an emergency bypass of highly diluted stormwater and wastewater from the West Point plant.

While rain and snow showers are forecast near the end of the workweek, and early next week, no additional emergency bypasses of stormwater and wastewater are likely in the near term.
