The waste streams from the Manchester Water Treatment Plant are captured and clarified by a series of sedimentation lagoons. Because these lagoons are located below the hydraulic gradeline of the plant's headworks, we must pump the effluent from these lagoons to allow recycle. The lagoon level is regulated by a handwheel‐operated sluice overflow weir. The effluent that leaves the lagoon often contains leaves, sticks, and other floating debris, which routinely clogs the impellers of the solids‐handling pumps. We developed a subsurface lift station to limit the amount of solids passing through the system.
