2025 Wastewater Facilities Expansion

Project Overview

WHAT IS THE CITY WORKING ON?

The City has been working on upgrading its wastewater treatment facilities to meet growing demands. The City partially completed facilities planning in 2018, resulting in a Phase 1 project expanding liquid treatment capacity while enabling highly effective phosphorus removal. That planning effort deferred solids handling planning until after the liquid treatment capacity expansion project’s completion since the new liquid treatment processes affected the solids handling capacity of the facility. In 2023, the City completed a facilities plan amendment addressing the solids handling capacity. Several feasible alternatives were evaluated. After careful consideration, Alternative 2 was chosen for implementation. This alternative focuses on sustainability, resiliency, and future-proofing the facility for improved treatment effectiveness.

WHY IS THE PROJECT NEEDED?

The need for this project arises from the city's tremendous current (and projected future) growth and development which strains the existing infrastructure. The current equipment is aging. Existing treatment equipment has been rehabilitated, but is at the end of its useful life. The existing processes are not sustainable, and there is not enough storage capacity available onsite to meet WDNR regulations. These strained conditions exist NOW and will continue to worsen as the City continues to grow. Growth projections are estimated at 40% over the next 20 years.

Federal grants, funding, and incentives are available to offset the cost of the project (investment), presenting an opportunity for the City to make a generational investment in treatment effectiveness that is consistent with the City’s goals for sustainability. By securing federal grants and utilizing available incentives, the City aims to minimize borrowing costs for this essential infrastructure upgrade.

FUNDING SOURCES 

The City has secured federal grants, will pursue available incentives, and has funds on hand to reduce the required borrowing.

WHAT DOES THIS MEAN FOR RATEPAYERS? 

The project maintains very affordable rates compared to neighboring cities while providing the required improvements to maintain the City’s ability to provide exceptional wastewater treatment. While the project will cause a rate increase to households in the service area, the projected rates will still remain below regional and national averages.
