The project focused on restoring system reliability and <br />extending service life through a combination of advanced hydraulic evaluation and <br />targeted structural rehabilitation. A detailed hydraulic analysis was performed to reassess <br />system demands and confirm the need for pump upsizing, ensuring the station could <br />efficiently accommodate varying flow and pressure conditions within the collection <br />system. <br />The rehabilitated station was designed with a four-pump configuration consisting of two <br />30-horsepower and two 10-horsepower submersible pumps. This arrangement allows <br />the station to operate across a wide range of system curves without the use of variable <br />frequency drives, in accordance with the City’s operational preferences. All mechanical, <br />piping, and valve components within the station were replaced to provide a fully <br />modernized and robust pumping system. <br />Given the severely corroded condition of the existing wet well and valve vault, specialized <br />structural engineering expertise was incorporated to develop a concrete rehabilitation <br />program. This included surface restoration, protective lining systems, and structural <br />repairs to address deterioration and ensure long-term durability in a corrosive wastewater <br />environment. <br />In addition to the station rehabilitation, the project included relocation of existing <br />gravity sewer infrastructure and the design of a new discharge force main to integrate <br />the upgraded station into the surrounding system. The project also encompassed <br />preparation of all required permits and coordination with regulatory agencies, along with <br />construction-phase engineering services to support implementation, respond to field <br />conditions, and verify compliance with the design intent. <br />Dates <br />06/2024 - 10/2025 <br />Cost <br />CHA Fee: <br />$210k <br />Construction: <br />~$3.1M <br />Reference <br />Bryan Sevilla <br />T: (305) 673-7080 <br />E: bryansevilla@miamibeachfl. <br />gov
