This project included the demolition and removal of the existing sewer control structure concrete roof, appurtenances within the control structure and wet wells, and all electrical conduits, hydraulic lines, brackets, and other items associated with existing Slide Gates 1 through 6. It was necessary to construct bypass piping and pumping in order to facilitate the cleaning of the sewer pump station wet wells prior to rehabilitation, which included the coating of two wet wells and control structure. After the new coating was applied, it was necessary to install new FRP grating and support system in the control structure, new safety chain system in each wet well, five new slide gates, and permanent plug at existing Slide Gate 4. Also included was the construction of a new concrete roof for control structure and installation of four new roof access hatches, along with dewatering and construction of all temporary shoring systems required to complete the work.
