Description: The PS 28 lift station collects flow from its own collection basin, and there are two upstream pump stations, PS 13 and 14. Wastewater entering the station from the gravity collection system must pass through the influent screening structure, which is located on the east side of the station. The gravity influent to the structure comes from 30-inch and 24-inch lines that enter the structure on its east side from the north and south, respectively. Flow channels divert the entering flow through a comminutor (channel grinder) prior to entering the station’s wet well via a 30-inch influent line. Once in the wet well, a triplex lift station consisting of three 200 horsepower (HP) (two in operation, one standby unit) pumps sends the gravity influent into the 36-inch discharge header associated with the booster pumps. The work includes the complete rehabilitation of the pump station building and demolition and construction of a new electrical building, including but not limited to the demolition of the existing electrical building, bypass pumping, interior demolition of the pump station building, complete replacement of all pumps piping and appurtenances, install new generator and fuel tank, new odor control, new ventilation / AC (HVAC) system, improve site accessibility, electrical, plumbing, instrumentation and site work, storm proof and rehabilitate the pump station by installing watertight hatches and hurricane proof windows and doors, perform all structural and ancillary work as necessary to maintain the structural integrity and prevent water intrusion to the buildings, and the complete replacement of approximately 1,100 LF 30” DIP discharge force main via open cut. The work also includes pump optimization for energy efficiency, as feasible.
