We’re committed to clean water, community health, and the environment. We work around the clock to clean the Eugene-Springfield area’s wastewater, 365 days a year- it’s a big job, with 11 billion gallons treated annually. Join us in helping to keep the Willamette River clean!

Our Wastewater Treatment Process

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, 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 35 million gallons of wastewater every day. That’s the equivalent to filling 53 Olympic-sized swimming pools. The treatment processes we use protect the community, downstream users, and the Willamette River ecosystem by consistently removing more than 97.5% of pollutants.
