Project Overview: EU180
This project will improve a sewage transport system by upgrading the existing lift station and connecting pipes so that the system can handle more sewage in the future. The existing lift station receives sewage from most of the northwest portion of the city and is near its capacity limit. It currently requires frequent maintenance to remain in service. The new lift station will have a design capacity of 18 million gallons per day and will require less maintenance.
What is a lift station?
Typically, sewage (wastewater) travels underground in sloped pipelines using gravity to allow it to flow naturally. However, in areas where the natural slope of the land doesn’t allow sewage to flow freely, lift stations are used to pump the sewage from a lower elevation to a higher elevation. Pumping to a higher elevation allows the sewage to flow by gravity, through connected pipes, until it reaches its final destination of the sanitary sewer treatment plan.
Project Status – April 2024
City Council awarded the project to IMCO Construction on May 8, 2023. The project is anticipated to be complete in early 2026. Crews have completed the deep excavation (nearly 32 feet below the ground surface) and have completed the first of many concrete pours for the lift station base.
Crews have begun work in Roeder Avenue to replace existing pipes. Some travel lanes will be reduced during the day and traffic controls are in place. Access to local businesses remains open. We ask drivers, cyclists, and pedestrians to remain aware of shifting conditions in the roadway.
Funding
A $17.5 million contract for project construction was awarded to IMCO Construction by City Council (Agenda Bill 23707) in May 2023. This project is funded by the City’s Wastewater Fund.
