Our Industrial Waste Program is in charge of preventing pollution from entering the wastewater system in the first place. That’s also where local business can make…
Operators work hands-on, out at our treatment plants Operators watch over large and complex industrial equipment and the flows going through them – from both on-the-ground and from computer monitoring systems.

The West Point Treatment Plant processes about 100 million gallons of wastewater each day, and up to 440 million gallons during heavy rains. While the plant’s operators are working hard to keep the treatment process flowing smoothly, a momentary lapse of power supply quality can bring vital equipment operations to a hard stop. That’s why in February 2021, King County Executive Dow Constantine signed an emergency declaration and the King County Council authorized up to $65 million to provide West Point with more reliable power. The team…
