Wastewater Master Plan Update

Project Background

The City of Springfield is embarking on a project to update our Wastewater Master Plan. Through this work, the City will identify needed improvements to the local wastewater system, based on current conditions and anticipated growth over the next 20 years.

Springfield’s Wastewater Master Plan was last updated in 2008, and all capital improvements identified in that version of the plan have been constructed, so the plan is being updated again in 2022, in collaboration with contractor Murraysmith Inc.

Project Purpose & Outcomes

The purpose of updating Springfield’s Wastewater Master Plan is to identify needed improvements to the City’s wastewater collection system for increased capacity for future 2042 planning year conditions. See below for the target outcomes of the project.

About Springfield’s Wastewater System

On the left, the wastewater system is represented with wastewater flowing from a drain inside a home, through a private lateral pipe, and connecting to the city wastewater pipe which leads to the wastewater treatment facility. On the right, the stormwater system is represented. Rain falls onto surfaces like streets, down through storm drains to catch basins, and then out to rivers and streams through the city's stormwater pipe.

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.

Frequently Asked Questions

The City of Springfield strategically manages and maintains 250 miles of wastewater pipes. These pipes transport wastewater from Springfield homes and businesses to the Metropolitan Wastewater Management Commission’s (MWMC) regional wastewater treatment plant in North Eugene. The MWMC cleans water for the Eugene-Springfield area and then returns the cleaned water to the Willamette River. The MWMC is a partnership between the cities of Springfield and Eugene, along with Lane County.

Wastewater collection is an essential community service. Effective management of the wastewater collection system is critical to the health and vitality of the Springfield community, surrounding water quality, and the local environment.

The City of Springfield’s Operations Division within the Development & Public Works Department performs a variety of activities to manage and maintain the wastewater system. This work is guided by the City’s Capacity, Management, Operations, and Maintenance or CMOM program. Proactive maintenance activities include close circuit TV inspections of wastewater pipe using a camera, high velocity cleaning, and flow metering or measuring the amount of water flowing through the pipes. Additionally, the team repairs leaking sections of wastewater pipes as needed.

Springfield also maintains a hydraulic model to predict areas in the collection system where issues may occur. Larger scale improvements that are needed are added to the City’s five-year Capital Improvement Program and capital budget.

The City of Springfield has an intergovernmental agreement with the City of Eugene’s Wastewater Division for maintaining the pump stations located throughout Springfield. These pump stations lift the water up and push it down through the next series of pipes.

In addition to management of local wastewater pipes throughout Springfield, City staff also provide administration for regional wastewater services provided by the MWMC. Springfield staff work alongside City of Eugene staff, who provide operations of regional MWMC facilities.

An update to Springfield’s Wastewater Master Plan is important for identifying where improvements for increased capacity are needed and the best and most cost-effective way to meet those needs.

The City’s last update of its Wastewater Master Plan was completed in 2008, and all of the capital improvements identified in the plan have been completed. A 2022 update to the plan will recommend additional improvements to the City’s wastewater collection system to increase capacity and eliminate identified deficiencies, in anticipation of growth over the next 20 years.

This update to Springfield’s Wastewater Master Plan is budgeted through the Development & Public Works Department’s planning section for infrastructure planning. Funding for the project comes from local wastewater fees paid by customers through the Springfield Utility Board.

As part of the Wastewater Master Plan, a long-term funding plan will be developed to identify options to ensure adequate revenue to address the capital needs of Springfield’s wastewater collection system.

This long-term funding plan will be developed with consideration for rate impacts to community members and businesses and with transparency to stakeholders. The community will have the opportunity to share their input related to any future rate impacts.

There will be opportunities at key project milestones for Springfield community members and project partners to review draft materials, ask questions, and provide input on the project. Be sure to reference this webpage for future opportunities for providing feedback.

During any point of the project, community members are welcome to contact Molly Markarian, Senior Planner and Project Manager. City staff welcome questions about the project.

Community members interested in staying up-to-date about this project are also encouraged to subscribe to the Development and Public Works Department’s quarterly newsletter.
