Pipes & Pumps
The City operates a large and complex wastewater collection system, which includes 250 miles of wastewater pipe varying from 6 to 60 inches in diameter. This system of pipes and pumps moves wastewater from Springfield homes and businesses to the Metropolitan Wastewater Management Commission‘s (MWMC) regional wastewater treatment plant in North Eugene, where all wastewater from the Eugene-Springfield area is treated before it’s returned to the Willamette River.
Springfield’s Approach to Wastewater Management
Effective conveyance and treatment of wastewater is critical to the health and vitality of the Springfield community, surrounding water quality, and the local environment.
Guided by the City’s Capacity, Management, Operations, and Maintenance (CMOM) Program, the City operates, maintains, inspects, and cleans its wastewater collection system. The CMOM Program helps to preserve and extend the life of wastewater infrastructure, as well as prevent overflows of wastewater into local parks, yards, streets, or waterways, known as sanitary sewer overflows or SSOs. Check out the video below to learn more about Springfield’s CMOM Program.
The City also uses a hydrologic and hydraulic model along with various inspection techniques to identify locations where maintenance holes and pipes can be repaired to reduce infiltration and inflow (I&I), groundwater and stormwater that enter the wastewater system and increase the flow being conveyed to the wastewater treatment plant. These tools have also helped the City identify downspouts, sump pumps, and area drains that are improperly connected to the wastewater system.
