RESCU PROGRAM: Front of Plant Project

An important milestone for the Front of Plant project has been reached; the design package is complete and submitted to SVCW by Shea/Parsons Joint Venture (SPJV) design team. With the design completed, SVCW and SPJV, continue their work on the operations control narrative, which documents the operating steps for the entire FoP system.  The FoP system operations will be automated, with oversight by experienced SVCW operations staff.  One of the keys to effective system operations is a well-designed control narrative, requiring close coordination between SVCW and SPJV.  Using the progressive design build (PDB) contract delivery method, involving close collaboration between the partners, continues to support development of the control narrative in the same way the physical design of the FoP project was developed.  A central element of the control narrative describes the various pumping modes of the Receiving Lift Station (RLS) and how these modes will be used to address varying wastewater influent flow conditions in concert with performance requirements of the wastewater treatment plant receiving the influent flow.  

On the construction side, SPJV has completed placement of 27 of 29 first-level wall panels for the Headworks facility, which is one of the three main elements of the FoP project. Work on the second level deck continues, with plans for placing the majority of the second level deck by the end of this month (January). Mass excavation of the vertical Surge and Flow Splitter (SFS) shaft commenced in October 2019 and was completed in December 2019. Work within the RLS shaft continues with installation of reinforcing steel bars (known as rebar) in preparation for pouring the concrete base of the RLS later in January.  The image below and time lapse videos at the end of the RESCU website show how far the project has progressed in just a few months.
