Overview
The City of Frontenac is required to construct a new wastewater treatment plant to meet updated state and federal environmental regulations.
Frontenac’s current wastewater system includes sewer lines, lift stations, and a lagoon treatment facility. While the lagoon has served the community for many years, it was designed under older standards and cannot reliably meet today’s requirements.
Why a New Treatment Plant Is Required
State and federal regulations now require significantly lower limits for nutrients such as phosphorus and ammonia to protect downstream water quality.
Engineering studies and coordination with state regulators have confirmed that Frontenac’s lagoon system cannot consistently meet these standards.
This project is required to maintain regulatory compliance.
What the New Plant Will Do
A mechanical treatment facility uses a controlled, multi-step process to remove:
- Solids
- Nutrients
- Pathogens
This ensures treated water meets current environmental standards and provides long-term reliability for the City’s wastewater system.
Project Scope and Cost
Planning for this project began in 2019. The estimated total cost is approximately $20.9 million.
The project includes:
- Construction of a new mechanical treatment plant
- Upgraded pumping, controls, and monitoring systems
- Processes designed to meet phosphorus and ammonia limits
- Long-term regulatory compliance and system reliability
Construction will be phased to maintain continuous wastewater service.
Impact on Sewer Rates
The project will be funded through a combination of user rates and sales tax.
Sewer rates will remain steady for the duration of 2026 while the city assesses the project cost and impact of sales tax revenues.
Current Project Status
The City has:
-
Completed multiple engineering and feasibility studies
-
Identified a permanent treatment site
-
Coordinated with state regulators
-
Begun advancing design, financing, and project planning
Commitment to the Community
Frontenac is committed to protecting public health, the environment, and the long-term affordability of essential services. This project is being planned carefully, reviewed by state regulators, and will be implemented with transparency.
Updates will be provided as major milestones are reached.
