Town of Walkerton Combined Sewer & Waste Water Facility

JPR performed a study that would accomplish two primary goals for the Town of Walkerton. The first, to determine if separation of the Town’s stormwater and sanitary sewers was a cost-effective solution for the long-term management of storm flows. The second, to remove cold weather ammonia-nitrogen from the lagoon-based wastewater treatment facility.

Working with the Town, IDEM and the University of Notre Dame, many options were explored including a partial separation plan. However, after much consideration and processing of an Agreed Order with IDEM, complete treatment was selected. The Town’s project included construction of a new 0.400 MGD extended aeration wastewater treatment facility, a storm event equalization facility, and upgrades to 10 lift stations.

In January 2015, the Town’s new facility was placed in full operation. Since commissioning, it continues to perform with our standing results that allow the Town to meet the Agreed Order terms with IDEM.

JPR’s services included, but were not limited to, a Preliminary Engineering Report and an upgrade/replacement feasibility study, along with survey, design, permitting, construction administration and inspection, and coordination with funding agencies. Project features included an innovative design that allowed the new treatment plant to sit inside the former lagoon. They also included equipment and telemetry upgrades to all lift stations, along with a new control room, chemical room, UV disinfection system, headworks, a maintenance garage expansion, and new plant tanks.
