Front of Plant June 2022

At the Front of Plant site, construction work progresses at the Surge and Flow Splitter (SFS) shaft. SVCW’s contractor partner, Shea Parsons Joint Venture (SPJV), has completed installation of pipe penetrations on the north and south sides of the shaft, with the curing of concrete in progress for pipe supports. With the structural work at the SFS shaft walls ending, preparations for architectural work on the interior of the shaft have begun. SPJV is performing sweep blasting on the shaft walls and floor, a cleaning method used to remove loose material and roughen surfaces prior to applying coating. Simultaneously, SPJV completed installing rebar and placing concrete for the precast SFS roof sections within the forms which were set up onsite near the SFS shaft. These roof sections will be placed over the SFS opening after interior wall coating is complete.

At the Receiving Lift Station (RLS), SPJV continues installing the six new RLS pumps, which will pump raw wastewater entering the RLS shaft from the gravity tunnel to the new Headworks Facility. The crew completed installing the pumps as well as the steel sole plates for each pump, for structural and vibration support. This work will be followed by performing piping connections on the suction and discharge sides of each pump. Additional electrical work at the RLS includes installation of conduits, gas detection system and other instrumentation. The pump installation work is being performed in coordination with the SVCW Operations and Maintenance team as a training opportunity. At the Headworks Facility, installation continues for electrical conduits and miscellaneous equipment.
