After five years of perfect compliance with environmental permits, King County’s Carnation Treatment Plant earned the coveted Platinum Peak Performance Award from the National Association of Clean Water Agencies.
To be eligible for the award, the plant had to meet stringent pollutant removal requirements for its discharges under its National Pollutant Discharge Elimination System (NPDES) permit.
The Carnation Treatment Plant has been in operation since 2008, serving about 2,000 people who live and work within the Carnation city limits. With its advanced technology and innovative design, the Carnation Treatment Plant also produces exceptionally high-quality recycled water that’s being used to enhance wetlands and preserve local habitat near the Chinook Bend Natural Area.
The plant has been designed with numerous green features that minimize impacts on the environment, conserve resources and maximize energy efficiency.
The plant was also the recipient of the Washington State Department of Ecology’s “Outstanding Performance Award” for perfect compliance with all permit conditions in 2014.
