Water System Improvements Phases 1 & 2

HWC worked with the City of Jasonville, Indiana to complete a master plan of the City’s water system. The study was intended to address NPDES permit violations related to water treatment facility backwash discharge and other system needs. HWC also performed survey services for this project. 

The master plan, which was funded by an IOCRA grant, recommended a two-phased approach to improve the system.

Phase 1 addressed regulatory compliance issues at the plant. This phase included a new filter backwash lagoon with liner and baffles, new backup power generators at the well field, well field transmission main, and electrical service replacement.

Phase 2 included capital improvements to address depreciated equipment at the treatment plant, replacing a failing supply well, and installing new transmission mains. This phase included the replacement of two gravity filtration units, new high-service pumps and interior piping, a new water supply well, and a new two-mile water supply main in a remote area of the distribution system.

Sanitary District Project 20 – Thompson Ditch/Poplar Street Relief Interceptor

HWC worked with the Terre Haute Sanitary District to complete this $4.5 million relief interceptor project.

The constructed interceptor in the Thompson Ditch drainage way now intercepts flow from Seelyville and conveys them to the Southside Lift Station via 36”, 48”, and 60” interceptors. The interceptor also collects flow from a combination sewer and force main constructed on Poplar Street to relieve overburdened sewers on Poplar Street.

Finally, an existing regional lift station near the intersection of Poplar Street and SR 46 was upgraded and replaced.

The project involved survey services, significant road reconstruction, traffic planning, land acquisition, and public awareness.

Shakamak State Park Regionalization & 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 DNR from having to operate a wastewater treatment facility
• Addressing the hydraulic capacity issues and difficulty in meeting ammonia limits at Jasonville’s existing WWTF

To address the needs discussed above, the recommended project in the PER includes 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 include 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 include 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 along with decommissioning Shakamak’s existing WWTF. The improvements to Jasonville’s WWTF include removal of the lagoon cover system, installation of a new Submerged Attached Growth Reactor (SAGR) Treatment System, and additional wet weather flow storage. HWC also performed survey services for this project. 

The project has been bid and is expected to be completed in 2024. The construction cost is $8.2 million.
