The scope of work included construction of the new headworks building, influent pump station, and overflow screw pump station. The influent pump station required extensive earthwork, including a 30-foot deep excavation supported by a sheet-piling cofferdam, and the use of a 40,000-pound crane for key equipment placement. The overflow station features two 6-foot diameter screw pumps capable of handling more than 10,000 gallons per minute (15 million gallons per day) when influent flow exceeds the plant’s processing capacity.
Story Construction crews self-performed cast-in-place concrete, buried piping, process piping, and installation of process equipment, demonstrating the firm’s commitment to quality and hands-on project execution. Throughout the project, crews managed site challenges including poor soil conditions and high groundwater associated with proximity to a floodplain.
City staff and project partners praised the Story team for their attention to detail, proactive communication, and ability to adapt to supply chain challenges, contributing to a well-coordinated construction effort.
