Shakamak State Park Regionalization and Wastewater System Improvements

HWC completed a Preliminary Engineering Report (PER) for funding through the Indiana Finance Authority (IFA)’s State Revolving Fund (SRF) Program for this project. The PER was prepared to address several needs, including:

• Significant inflow and infiltration in the Shakamak State Park collection system
• Aging and deteriorating equipment and controls at the Shakamak Wastewater Treatment Facility (WWTF)
• Alleviating IDNR from having to operate a wastewater treatment facility
• Addressing the hydraulic capacity issues and difficulty meeting ammonia limits at Jasonville’s existing WWTF

To address the needs discussed above, the recommended project in the PER included the Shakamak State Park collection system rehabilitation, wastewater conveyance infrastructure from Shakamak State Park to the City of Jasonville’s WWTF, and upgrades to Jasonville’s existing WWTF. The Shakamak State Park collection system improvements included gravity sewer rehabilitation, consisting of lining approximately 3,745 LF of gravity sewer mains via cured-in-place pipe (CIPP), along with other miscellaneous repairs and upgrades to the park’s collection system. The wastewater conveyance improvements included upgrading Shakamak’s existing Lift Station Number Five with new pumps and installing approximately three miles of force main from the lift station to Jasonville’s WWTF for treatment of park flows along with decommissioning Shakamak’s existing WWTF. The improvements to Jasonville’s WWTF included the removal of the lagoon cover system, installation of a new submerged attached growth reactor (SAGR) treatment system, and additional flow equalization storage volume.

The project was completed in January of 2025 with a construction cost of $8.37 million.
