Regional Treatment Plant
The wastewater treatment plant, also known as the Eugene-Springfield Water Pollution Control Facility (WPCF), is a state-of-the-art facility located on River Avenue in Eugene. The treatment plant and 49 pump stations distributed across Eugene and Springfield operate 24 hours a day, 7 days a week, 365 days a year to collect and treat wastewater from homes, businesses, and industries before returning the cleaned water, or effluent, to the Willamette River. Through advanced technology and processes, the facility cleans, on average, up to 30 million gallons of wastewater every day. That's the equivalent to filling 106 Olympic-sized swimming pools. The treatment processes we use protect the community, downstream users, and the Willamette River ecosystem by consistently removing more than 95% of pollutants.
Wastewater Treatment Process
The regional wastewater program staff strive to produce effluent, or treated water, that doesn't just meet standards, but has better quality than the maximum allowable limits for the many parameters defined by federal and state guidelines.
