Thomas & Hutton (T&H) is pleased to announce that our project, Central Berkeley WWTP Flow Diversion has been honored as a 2021 Project of the Year Award Winner by the American Public Works Association South Carolina Chapter (APWA SC). APWA SC honors top public works projects across the state annually to promote excellence in the management and administration of public works projects by recognizing the alliance between the managing agency, the consultant/architect/engineer, and the contractor who, working together, complete public works projects. Berkeley County Water and Sanitation (BCWS) retained T&H for the design and planning of the Central Berkeley WWTP Flow Diversion project.

The purpose of the project was to improve wastewater conveyance for users within the Cane Bay and Pine Hill developments, as well as the upcoming developments in the Wildcat Tract. These areas constitute the largest and fastest-growing portion of Berkeley County, with buildout to exceed 15,000 homes, along with schools and associated mixed-use retail and commercial. The CBWWTP project also served to alleviate the potential for maxing out the treatment capacity of the Lower Berkeley Wastewater Treatment Plant (LBWWTP) by diverting flows from the above-referenced areas to the Central Berkeley Wastewater Treatment Plant (CBWWTP). The phased project involved redirecting discharge beginning from the BCWS Pump Station #151 (PS 151) to the newly designed BCWS Pump Station #161 (PS 161), and onto the CBWWTP. T&H created a wastewater master plan to guide the implementation of the phased project to serve the above-referenced and surrounding areas for the next 30 years.

The project involved the installation of nearly seven miles of force mains (nine miles counting each leg of the dual 18-inch force mains separately), construction of a large regional wastewater pump station, and the upgrade of an existing regional pump station. All improvements were completed with minimal impact on the surrounding community and existing wetlands. This project exemplifies the innovative and strategic ability of a public utility to rethink the use of their existing infrastructure. BCWS now possesses the treatment capacity for future development within the vicinity of the LBWWTP and can maximize the productivity of the CBWWTP

This included an analysis and selection of pump station and route locations and subsequent design of all associated infrastructure. T&H would like to congratulate our fellow Project of the Year honorees and thank our partners at BCWS.
