McDowell WRRF Primary Clarifiers and Headworks & Influent Pumping Station Rehabilitation

The project involves comprehensive rehabilitation work at the McDowell WRRF, focusing on the replacement and upgrade of critical mechanical and structural components within the Primary Clarifiers and Headworks & Influent Pumping Station. Key activities include the demolition and installation of new mechanisms for Primary Clarifier No. 4 and No. 5, as well as the replacement of pinch valves in BTB No. 3 and BTB No. 4 Rate Control Structures with modern plug valves. Grit suction and discharge piping, associated valves, and appurtenances within the Headworks and Influent Pumping Station will be fully replaced, and knife gate valves on the discharge header of the first stage pumps will be upgraded to plug valves for improved performance and reliability. Additionally, existing slide gates at Primary Clarifier No. 4, Primary Clarifier No. 5, and the Headworks and Influent Pumping Station will be rehabilitated to maintain operational efficiency and system integrity.
