This project creates a new potable fire supply loop for the City’s Combined Wastewater Treatment Plant (Facility) using a portion of the existing non-potable supply piping, and by adding new piping that connects to the City’s potable water distribution system. The existing non-potable system that remains will also be modified to meet existing irrigation and sedimentation basin wash down needs for the Facility. The work includes, but is not limited to furnishing and installing approximately 950 linear feet of water pipeline, one hydropneumatic tank, one water booster pump, three hydrants, electrical wiring and monitoring equipment; removal of three existing line shaft turbine well pumps and installation of three new 25 horsepower submersible well pumps; demo of existing and construction of new wellheads and discharge piping, new well column piping, instrumentation, and performing well casing videos; pavement restoration; recycling construction debris; site cleanup; and construction of all the associated appurtenances as shown on the Plans and/or as indicated in these Contract Documents. Furnish and install all material, labor, tools, equipment, and services necessary for a complete, in-place operating system. The Facility has undergone several major infrastructure modifications since its original construction in 1952. There are many abandoned pipelines within the area proposed for construction. Unless otherwise indicated existing and abandoned utility locations shown in the Plans are approximations. Prior to pavement cutting or trenching for pipeline installation, connection points to existing pipelines, depths and alignments of new pipelines shall be field verified. No additional compensation will be provided for field verification related to determination of existing pipeline depth or location. All equipment and materials furnished that are to remain a part of the Facility shall be new, except where re-use is specifically called for. Work shall be confined to existing City owned property unless Contractor makes alternative arrangements with adjacent private property owners. The existing pipe tunnel has removable concrete roof sections along its length. Removal requires installation of new lifting anchors. Panels weigh up to 4 tons each. Re-installation requires placement of new gaskets and sealing material. For additional project information contact: Mark Elliott, Associate Engineer at (916) 808-8894
