Madison Street Underpass Flooding Mitigation

HWC provided planning, design, and project management services for the Madison Street Underpass Flooding Mitigation project in Muncie, Indiana.

Utilizing conveyance upgrades in conjunction with stormwater pumping and storage, HWC addressed a critical drainage hazard in the heart of Muncie. Madison Street, the arterial north/south road through the City, crosses under three railroad lines, which creates a regional low-point that ties into one of the City’s CSO trunk-lines.

The study included hydrologic modeling of contributing watersheds, hydraulic modeling of several nearby CSO and separate storm sewer systems, and the development of numerous design alternatives to determine a solution to address persistent flooding and stormwater collection.

The recommended project provided capacity for the 100-year event and had an approximate cost of $6.7 million. The first phase of the project provided protection up to a 10-year event at an initial approximate cost of $4 million. Future phases, if implemented, will bring the system up to the full 100-year capacity.

Improvements included two 13,000 GPM 250hp storm pumps, two 1,600 GPM 20hp force main pumps, a 750,000-gallon ground storage tank, 2,200’ of 16” force main directionally drilled, backup generator, wet well, control valves, and 500’ of gravity storm sewers to the station. The first phase was funded via the Guaranteed Savings/Guaranteed Maximum Price (GMAX) procurement method, and Bowen Engineering was the selected savings provider/contractor, working closely with HWC’s staff during design and construction.

2nd Street Rehabilitation

HWC replaced all sidewalks and curb and gutter in this downtown District of Aurora, Indiana. This project included minor drainage improvements, as well as the installation of pavement markings, new signage, and decorative crosswalks using pavers. ADA compliant curb ramps were also constructed and the pavement received a preventative maintenance mill and overlay of 1.5”. Coordination with business owners was critical as sidewalk was removed and replaced and as milling and paving operations ensued. HWC not only designed the project, but developed the bidding documents and conducted construction observation and administration. The project was completed at the end of 2018.

Main Street Rehabilitation

HWC provided both crack sealing and a PM 1.5” mill and overlay in different sections of this Main Street Rehabilitation project. HWC also met with the Town and Contractor to identify specific areas that required full-depth patching.

Project improvements included reconstruction of curb and gutter and sidewalks, ADA curb ramps, minor drainage improvements to the storm sewer system, and reworking of sidewalks and curb ramps in front of the Town Hall to improve pedestrian and ADA access.

This project required design, bidding services, construction observation, and administration. Throughout the project, HWC kept the Town informed on the construction status and involved them when necessary to respond to the Contractor’s questions and concerns. The project was completed at the end of 2018.

Wastewater Treatment & Phosphorus Removal

HWC assisted the City of Terre Haute with a major upgrade and expansion of their wastewater treatment facility as part of the Combined Sewer Overflow (CSO) Long-Term Control Plan (LTCP) and to address depreciation and compliance issues with the 24 MGD facility.

First, HWC completed design and engineering services for the biosolids storage and handling portion of the City’s Wastewater Treatment Facility Upgrade and Expansion project. The $120 million project was completed in 2015 and included improvements to all areas of the facility to accommodate peak flows of up to 48 million GPD as required by the approved CSO LTCP. The biosolids storage portion of the project included 10 million gallons of storage capacity provided by four 2.5 million-gallon, pre-stressed concrete storage tanks with aeration and mixing systems contained in two buildings that serve a pair of the new tanks. The design also incorporated liquid sludge loading stations and associated piping and incidental work to that area of the project site. As part of a team of consultants completing the overall project, HWC completed this portion of the project with an approximate construction cost of $20 million. 

Following completion of the plant expansion project, and in accordance with updated NPDES permit requirements, HWC provided design and construction inspection services for a $2 million phosphorus removal project for the 48 MGD wastewater treatment plant.  

As a result of new effluent limits imposed on the WWTP by the NPDES permit, HWC initially developed a compliance plan to identify the needed facilities for submission to the Indiana Department of Environmental Management (IDEM). HWC was responsible for the design of the chemical feed system and improvements to the anoxic system for biological phosphorus removal, which included 30” diameter anoxic piping and tank modifications, as well as the addition of chemical storage tanks, feed pumps, feed piping, and building renovations.

HWC also provided construction administration assistance, serving as the primary contact with the owner for the State Revolving Fund (SRF) to provide project financing.

The project was completed at the end of 2018.

City Center Plaza and Streetscape

HWC provided design and construction inspection services for downtown streetscape along 5th Street, 4th Street, Madison Avenue, and O&M Avenue in North Vernon, Indiana. Additionally, HWC was responsible for the planning and design of the City Center Plaza, which sits within the previous right-of-way of Short Street along Madison Avenue. The project not only improved pedestrian and vehicular circulation, but also highlighted community history in design details and added beautification through special paving, street trees, custom metal features, and ornamental lighting.
