Wet Weather Clarifier System Improvements

HWC worked with the City of New Albany, Indiana to complete their Wet Weather Clarifier System Improvements project.

The City of New Albany operates a 30 MGD treatment facility with discharge to the Ohio River. Due to excessive wet weather flows from the separate sanitary sewer system, flow rates up to 75 MGD are conveyed to the treatment facility. A passive overflow structure downstream of three oxidation ditches allows flows of up to 30 MGD to be conveyed to secondary clarifiers while excess flows are diverted to the wet weather clarifiers with an overall capacity of 48 MGD. There are six wet weather clarifiers with circular clarifier mechanisms in square concrete tanks along with all associated piping and equipment. The condition of the clarifiers had depreciated along with the RAS/WAS pumping systems and disinfection facilities for the wet weather flow train, such that the City desired to develop a plan to rehabilitate the wet weather clarification systems.

HWC was retained to develop a basis of design study for the wet weather processes and equipment for developing a final scope of work and budget for the proposed project. The resulting plan evaluated several different alternatives, including complete replacement of all systems with various clarifier tank layouts.

Based on budgetary considerations and the frequency of use of the wet weather clarification system, the selected plan included rehabilitation of the existing systems and equipment. The total project cost was approximately $1.75 million with construction completed in 2019. HWC provided survey, planning, design, bidding, and construction engineering/inspection services for the project.

Conservancy District Water System Improvements

The Van Bibber Lake Conservancy District completed significant improvements to their water system in 2023. The $9.4 million project includes construction of a new water treatment facility and complete replacement of their distribution system. The new water treatment facility included an aerator with detention tank, new vertical pressure filters, and a new building to reduce the very high levels of iron in the raw water. The new water distribution system included installation of 24,000’ of new 6” and 4” water main to replace the undersized and failing water mains under homes and structures. The project also included the installation of 430 new AMI water meters since the system was previously unmetered at each residence. This project will improve the water quality, pressure, and flow to all the residents of the Van Bibber Lake community. The project was funded with an Indiana Office of Community and Rural Affairs (IOCRA) grant, Indiana Finance Authority (IFA), State Revolving Fund (SRF) forgivable loan, and United States Department of Agriculture (USDA) Rural Development loan and grant. HWC performed the survey and design services for this project.

HWC worked with Lennar Homes to provide survey and land development services for the creation of a new townhome community in Carmel, Indiana. The small site developed 49 luxury townhomes on 4 acres. This new community made use of limited space to provide necessary green space and stormwater detention. This site developed in a growing area along 116th Street creating a unique urban lifestyle with connectivity to commercial areas as well as to the Carmel Monon Community Center.

Vernon Township Fire Station

HWC provided survey and land development services for a 12,500 SF building, which includes associated parking, fire truck access, and utility infrastructure. Two new entrance drives were designed along Vitality Drive; one on the south and one on the east, to provide ingress and egress for fire trucks from the building, as well as a drive to a parking area in the front of the building.

The existing pond was expanded in order to provide additional detention volume required to meet present day standards.
