West Point Treatment Plant restoration update for Feb. 18, 2017


Restoration work continues around the clock at the West Point Treatment Plant, which is treating wastewater. No emergency bypasses are anticipated under current weather forecasts for the next 24 hours.


With light to moderate rainfall in the last 24 hours, the West Point Treatment Plant is continuing to provide limited wastewater treatment. No emergency bypasses are anticipated under current weather forecasts for the next 24 hours.
Crews working around the clock at maximum staffing levels are making steady progress in restoring full wastewater treatment capacity following a Feb. 9 equipment failure during a period of record rainfall.
The plant currently has capacity to provide limited wastewater treatment of 250 million gallons per day – nearly double the amount needed to treat an average day this time of year.
Progress report for Feb. 18:
Approximately 40 workers are performing a number of jobs as part of restoration activities at West Point today, Feb. 18:

  • Crews have cleaned and sanitized about half of the treatment plant. This essential first step must be done before electrical and mechanical workers enter those areas to assess damage, and restore or replace damaged equipment. More areas of the plant are accessible every day, and the entire plant is expected to be dry enough for inspections by Feb. 24.
  • Employees and contractors are working in cleaned areas of the plant on electrical and mechanical systems, including removing and rehabilitating engines. Roughly one-third of this work is expected to be completed by the end of the day today.
  • King County engineers are working on the design and replacement of electrical panels, and consulting engineers are assisting in electrical restoration throughout the plant. 

Water quality monitoring:
Some local beaches have been affected by emergency bypasses of combined stormwater and wastewater, and crews have been regularly sampling water quality at those beaches. The last emergency bypass at the West Point plant ended at 6 a.m. on Thursday, Feb. 16, and signs have been in place along beaches north and south of the lighthouse at Discovery Park, and at Golden Gardens Park. Signs will be removed once bacteria levels are determined to be low by the Public Health - Seattle & King County.
Upcoming weather:
While some rain is expected over the next several days, forecast amounts don’t appear to be significant enough to exceed West Point’s current capacity of providing primary wastewater treatment to roughly 250 million gallons per day.
