Mechanic Street Pump Station Upgrade

Background

The Mechanic Street Wastewater Pumping Station is the largest in the City. The City developed a Pump Station Master Plan to perform limited upgrades. Pump failures and flooding events required temporary pump installation and repairs in 2023 that underscore the need for a comprehensive replacement and upgrade program. 

The City has contracted with the team of AECOM and Underwood Engineers to complete a feasibility study for a full facility replacement. The study is estimated to take 3-5 months (Aug-Dec 2024) to complete and will identify siting options and capacity needs for a new facility. The City anticipates to present concepts to the City Council and the community in early 2025 before moving forward with the project.  

Project (EF-13-SD-97): 

Project Status: Feasibility Study underway.

Estimated Cost: FY25 CIP Design Phase Costs: $4 Million. FY27 Construction Phase Costs: $21 Million. 

Funding Source: The City is exploring State and Federal funding sources
