Water Supply, Treatment, and Distribution Improvements

HWC completed a Preliminary Engineering Report (PER) for improvements to the Martinsville water system. The evaluation looked at supply, treatment, and distribution system improvements and made recommendations to address the most pressing needs. After working with the City and their project team to obtain funding and Indiana Utility Regulatory approval, HWC moved into the design phase.

The final project design was broken into two divisions of work. The first division included the design of three new 1,400 GPM wells within the existing well field, modifications to the fluoride room, a new office/lab building, interior improvements to the water treatment building, and miscellaneous site improvements. It also included the replacement of a remote booster station, which provides water to the Morgan-Monroe State Forest.

The second division consisted of a City-wide water main distribution system improvement project that included the replacement of over 13,000’ of 6-12” water mains, 80 fire hydrants, and nearly 140 service lines. Special sequencing of work was required to accommodate I-69 detour traffic that was routed through the City.

The $6.2 million project was funded with an OCRA grant and an SRF loan, and construction was completed in 2021.

Prince’s Lakes, IN

Water System Improvements

This project included a 400,000-gallon elevated water storage tank to provide increased pressure and storage capacity, as well as enhanced fire protection for the Town. It also included 300’ of 24” water main under Driftwood River and 320’ of 24” water main under US 31 to provide a redundant water supply at critical locations since the system serves multiple entities including Camp Atterbury, Town of Trafalgar, Cordry-Sweetwater Conservancy District, as well as Prince’s Lakes. The project also included 8,000’ of new 12” water supply main and new high-service pumps to improve the reliability and efficiency of the water system.

The $5 million project was completed in 2021.

I-65 Water Service (Tank and Booster Station)

The scope of services for this project consisted of the design, contractor coordination, and needed construction administration for improvements to the Town’s water system in order to service the Jones Development Company (JDC) project south of Whiteland Road and west of the I-65 interchange. The improvements were necessary to serve an industrial development planned on a site southwest of the interchange which required water service including a fire flow of 2,400 gallons per minute at 20 psi for a two-hour duration. Since the existing system could not accommodate these requirements and additional developments in the areas east of Town are anticipated, improvements to the system were developed. The project included 10,000’ of 12” & 16” water mains, a 450,000-gallon ground storage tank, and a booster station with backup power and was completed in 2020. The system improvements followed recommendations included in a water system master plan developed by HWC.

Lieber SRA, Regionalization and Wastewater Improvements 

HWC completed a Preliminary Engineering Report (PER) for the Town of Cloverdale’s wastewater collection and treatment system for project funding through the Indiana Finance Authority’s (IFA) State Revolving Fund (SRF) loan program.

With HWC’s work in Cloverdale, the IFA retained HWC to complete a wastewater collection and treatment system analyses and PER for the Lieber State Recreation Area (SRA) in Putnam County. The Indiana Department of Natural Resources (DNR) is working with IFA to analyze their properties to enhance regional water quality through wastewater regionalization with their systems.

HWC’s recommendations for both the Cloverdale and Lieber SRA collection systems propose to reduce wet weather-based Inflow and Infiltration (I/I) to optimize the Cloverdale wastewater treatment facility. Both collection systems’ project recommendations include Cured-In-Place Pipe (CIPP), force main replacement, and manhole rehabilitation.

Due to the age of the Lieber SRA Wastewater Treatment Facility (WWTF), HWC further recommended that the facility be replaced with a regional lift station and approximately four miles of force main to deliver all the Lieber SRA wastewater to Cloverdale’s system for treatment.

For Cloverdale to be able to fully treat existing and the added regionalized flows, the Cloverdale WWTF needed various upgrades and repairs. Included within these recommended projects are headworks screening upgrade, blower replacement, upgraded internal water reuse system, aeration tank wall repairs, and circular clarifier covers with netting to reduce debris entering and clogging the process.

The total estimated cost of the recommended projects for Cloverdale and Lieber SRA is $8.5 million with construction in 2024.

CSO Long-Term Control Plan (LTCP) Phases 1 & 2

HWC completed an updated CSO Long-Term Control Plan (LTCP) for the City of Clinton’s combined sewer system. 

The study included mapping and evaluation of the City’s combined sanitary and storm sewer system, evaluation of the City’s wastewater treatment facility capacity, coordination of flow monitoring, development of a combined sewer system SWMM model for use in analysis of alternatives, evaluation of alternatives, and preparation and presentation of the report. 

The plan, which was required by the City’s NPDES permit, recommended improvements to control the volume and frequency of combined sewer overflows in the City’s system. The plan was approved by IDEM in December 2011. A State Revolving Fund (SRF) Preliminary Engineering Report (PER) was prepared in 2013 for Phase I work. 

HWC is completing engineering design and management of all LTCP recommended improvements. 

Phase 1, which consisted of floatable control screening, wastewater treatment facility headworks modifications, combined sewer separation via new storm sewers and outfall consolidation, was completed in 2016. 

The plan is based on a 20-year implementation schedule and will reduce the six existing overflows to three. Multiple areas of combined sewer separation are planned via installation of new storm sewers. Based on SWMM model results and financial analysis, the $10.5 million plan will require a Use Attainability Analysis (UAA) at the conclusion of implementation based on use of the presumptive approach for CSO control.
