Project Overview

The project includes rehabilitation via both open-cut and trenchless technology construction methods of three sanitary sewer trunk mains that cross beneath Interstate 494. These improvements will aid in reduction of inflow and infiltration (I&I) of groundwater into the sanitary sewer system, as well as reduce annual maintenance costs and extend the life of the pipe assets.

As of April 1, 2025, two of the three crossing rehabilitations have been completed. This includes the Aacron crossing just south of Highway 55 and the Northwest Business Campus crossing located north of Highway 55.

The final crossing referred to as the Prudential crossing, is expected to be constructed by June 2025. The crossing is just south of Bass Lake Road.

Anticipated Schedule

Construction: Spring 2024 - Spring 2025

The project includes repair and rehabilitation of select sanitary sewer trunk mains and manhole structures, including the cross beneath Interstate 494 along the Luce Line Trail. Pipe segments and manhole structures were selected for lining based on televising and inspecting the sanitary sewer system. These improvements will aid in reduction of inflow and infiltration (I&I) of groundwater into the sanitary sewer system, as well as reduce annual maintenance costs and extend the life of the pipe assets.

Project Overview

The Zachary Water Treatment Plant (WTP) Enhancements Project includes the addition of a plate settler system that will reduce filter backwash settling time, conserve water, and increase the operational efficiency of the existing water treatment facility. Work will include modifications to the interior and exterior of the plant to integrate the enhanced process into the existing system. The project also includes upgrades to the building automation systems (BAS) to the citywide standard and replacement of dehumidification and ventilation systems throughout the facility.

In 2023, the City of Plymouth was awarded $2 million in grant funding through the Community Grants Program administered by the U.S. Environmental Protection Agency (EPA). This grant funding program is designated for the planning , design, and construction of drinking water, wastewater, and stormwater infrastructure and for water quality protection.

Anticipated Schedule

Procurement of equipment began in late 2024, with the majority of work being completed in 2025. Most of the work will be completed while the facility remains operational to meet the city's water supply needs.
