Pea Ridge Creek Sanitary Sewer Improvements

Two upcoming sanitary sewer capacity projects are planned along the Pea Ridge Creek in north Springfield. Both projects are aimed at reducing the number of sanitary sewer overflows in the area by Doling_PeaRidge8x11increasing the size and capacity of underground sewer pipes. The projects will also provide capacity for any future growth and development in the area.

Springfield Environmental Services uses a variety of rehabilitation and maintenance methods to help repair and extend the life of Springfield’s sanitary sewer system. However, repeated cases of sanitary sewer overflows in the Pea Ridge Creek area indicate capacity issues that warrant construction to improve service and protect public health in the area.

The City is under an amended consent judgement with the Missouri Department of Natural Resources to eliminate sanitary sewer overflows. The City’s Overflow Control Plan was revised in early 2021 to establish a supplementary plan and timeline for investment in improving Springfield’s aging sanitary sewer system.   

Sanitary sewer improvements around Pea Ridge Creek are anticipated for construction beginning in fall of 2022. The combined cost of the projects is estimated at $5.2 million and will be funded using sanitary sewer reserve funds as outlined in the Supplemental Overflow Control Plan approved by City Council in April, 2021.

About the Projects

Pea Ridge Sanitary Sewer Project

The Pea Ridge Sanitary Sewer Project will follow along the north fork of the Pea Ridge Creek roughly between Heritage Avenue and National Avenue. The project will replace approximately 5,500 feet of an existing 12-inch sanitary sewer main with a new 24-inch pipe. About 1,200 feet of 18-inch main will also be added to run parallel with an existing pipe.

Doling Park Sanitary Sewer Project 

The Doling Park Sanitary Sewer Project will join with the Pea Ridge project near Heritage Avenue and will run south along the Doling Branch of Pea Ridge Creek into Doling Park. The project will replace roughly 6,900 feet of existing sanitary sewer main with larger diameter pipe up to 27 inches.

What are Sanitary Sewer Overflows?

The goal of these projects is to increase sewage capacity and reduce sanitary sewer overflows to improve service and protect public health in the area. The projects will also provide capacity for future growth and development.

Springfield operates a sanitary sewer system that is separate from the stormwater drainage system. The sanitary sewer collects wastewater from homes and businesses and carries it to one of two treatment plants where it is cleaned and then released back into local streams.

Rainwater can seep into the sanitary sewer system through cracks caused by age 

or tree roots. Sometimes during rainfall events, the system gets too full, causing untreated wastewater to overflow from manholes. Sanitary Sewer Overflows (SSOs) can also happen during dry weather, when major clogs form from tree roots, grease, wipes, and other items that don’t belong in the system.

Environmental Services uses a variety of methods to help repair and extend the life of Springfield’s aging sewer system and reduce overflows. Springfield is under an amended consent judgement with the Missouri Department of Natural Resources to eliminate sanitary sewer overflows. The City’s Overflow Control Plan was revised in early 2021 to establish a supplementary plan and timeline for investment in improving Springfield’s aging sanitary sewer system.


NEXT STEPS: Project appraisals and easement acquisition

The next step in this process will be to obtain appraisals of all properties directly impacted by the project. An appraiser with contractor Valbridge Property Advisors will visit each of the impacted properties in the months of December - January, 2021. Upon completion of the appraisals, a member of the City’s Right-Of-Way Department or a representative of City consultant, Toth & Associates, will reach out to each property owner via mail and potential door-to-door outreach to acquire necessary easements for the project.


What to Expect

Roadway Impacts: 

Doling Project – 1-2 day closure  of Norton Road for installation of sanitary sewer crossing.

Pea Ridge Project – Closure of Vernon Road and North National Avenue for the installation of underground pipe crossing the roadway. Closures expected to last 2-5 days.

Sanitary Sewer Service Impacts:

Minimal impacts are expected. Existing sanitary sewer mains will remain in service. Sewer service to individual households may be impacted for a few hours as household lateral sewer lines are moved over to new sewer mains. Homeowners will be notified of possible impacts as soon as details are available.
