Delaware County, IN
Countywide Bridge Inspection
HWC completed inspection, documentation, load rating, and reporting of Delaware County’s 193 bridges from 2006 through 2014.
Of the County’s 193 bridges, seven bridges required element level inspection, six bridges required fracture critical inspection, and six bridges required underwater inspection. In addition, 30 bridges were in a condition that required a load posting. Through coordination with INDOT and the County, HWC reduced the number of bridges requiring underwater inspections by 13 and eliminated five special detail inspections, saving thousands of dollars.

Irongate Storm Sewer Improvements Study
HWC provided engineering and survey services for Zionsville, Indiana to complete the development of a stormwater planning study for the Irongate Storm Sewer system and contributing drainage watershed. The study area was generally the area west of Ford Road, south of Oak Street, east of Lexington Drive, and north of the adjacent subdivision located south of the Irongate Subdivision.
The project included collecting GIS data which was then provided to the town, allowing them to update their own GIS system with more detailed information. Additionally, research into easements, property ownership, and sewer ownership was completed.
Through analysis of the existing system, HWC Engineering recommended two phases of proposed improvements that address the drainage issues. The study was completed in 2015 and construction of the first phase of improvements began in 2020.

Stormwater Improvement Projects
HWC provided survey, design, bidding, construction engineer, and inspection services for the six projects identified in the Batesville Stormwater Planning Study.
The six projects include:
-
- EGS Culvert Replacement & Ditch Improvements
- Huntersville/Woodlawn Storm Improvements
- Ripley/Vine Storm Sewer Replacement
- Sycamore Lake Water Quality Improvements
- Central Avenue Storm Sewer
- Park Avenue Storm Sewer
The projects included approximately 4,000 linear feet of storm sewer installation, along with a culvert replacement, ditch grading, and hydrodynamic separator.
The projects were completed at a construction cost of $1.3 million with construction funded through an OCRA grant.

Lafayette, IN
Service Area 21
HWC worked with the City of Lafayette to complete the Service Area 21 – Sewer & Water Utility Master Plan project. Service Area 21 refers to a 4,000-acre area outside the corporate limits of the City of Lafayette on the northeast side of the City at the I-65 and SR 25 interchange.
A crossing of Wildcat Creek and I-65 and connecting the water service to Lafayette’s dual water pressure zone system was evaluated as part of this study.
The area is largely agricultural but included several housing developments and the potential for commercial development, which created a need for water and wastewater utilities to service the area. The final plan included the phased extension of water and sewer services to the area. Future phases can extend these utilities throughout the entire service area and consist of a new well field for supplemental water supply due to the impacts of the proposed Hoosier Heartland corridor development. The construction cost for both phases developed in the plan was $5.8 million. HWC was responsible for design and construction management of Phase 1, which was completed in 2020.
Project Highlights:
- Economic development necessitated need for Phase 1 construction of water and sanitary extensions
- Multiple complex construction issues including creek crossing, highway crossing, and several right-of-way easements along a busy roadway corridor
- Opened areas northeast of Lafayette for potential future development
- Design of regional lift station to take minimal flows at start up and be expanded for future full build-out

Greenwood, IN
Western Regional Interceptor
HWC completed the design of the Western Regional Interceptor, which resulted from a master planning effort completed in conjunction with an IDEM-Agreed Order. The project included a new regional interceptor for the western sanitary sewer service area for the City of Greenwood, Indiana. The interceptor flows via gravity from White River Township to relieve the City’s existing interceptors in the old downtown area and east side, which were at capacity and experiencing surcharging and overflows. The new interceptor runs from SR 135 at the southeast end to SR 37 to the northwest. It generally follows Turkey Pen Creek and Honey Creek and runs adjacent to, or in between, several subdivisions that have experienced significant growth over the last 25 years. The interceptor connects to Citizens Energy Group’s existing 102” diameter South Marion County Regional Interceptor.
The interceptor ranges in size from 15’ to 60’ in diameter, allowed for 10 lift stations to be decommissioned, and included multiple sections constructed via trenchless technology due to road and waterway crossings.
The $65 million project was constructed in two phases and was completed in 2023 utilizing the guaranteed savings project delivery method.
Project Highlights:
- Project Construction Cost: $60 Million
- Approximately 55,000’ of gravity sewers ranging in size from 8” to 60” diameter
- Approximately 10,000’ of 24” diameter force main
- Jack and bore installations at several locations including SR 37, SR 135, Indiana Railroad, and several of the major County road crossings
- Pleasant Run Creek crossing, consisting of two parallel 42” pipes as required to maintain adequate cover under the creek
- Elimination of 10 existing pump stations
- Right-of-way easement acquisition for approximately 250 parcels along the interceptor route
