MP3.16 - North Bench Pump Station

Project Description: The construction of a drinking water pump station facility. The pump station will be a masonry block building with a standing seam metal roof equipped with five (5) vertical turbine drinking water pumps, motors, and pump cans; exposed suction manifold piping inside an attached valve pit; valves, flow meter, and miscellaneous fittings and appurtenances; discharge pipelines connecting to the existing distribution system; two bladder-style surge tanks; free-standing 1-ton workstation crane; installation of a new gas-powered back-up generator and new natural gas connection and meter; storm drain and floor drain structures and piping; and HVAC system. Electrical work will include the installation of a new power pole, buried power conduit, transformer, buried conduits for electrical connections; panels, including five (5) VFD panels; light poles and conduits for future security systems; and electrical work associated with the booster pump station, and control wiring for system PLCs. RTU is to be furnished by the OWNER. Site preparation will include the excavation of unsuitable foundation material, backfill, and compaction of approved material, forming and placement of concrete for footings, foundation walls, and floor slabs. Other site work will include clearing, grubbing, stripping,g and erosion control measures; asphalt surface placement and grading, concrete sidewalk; chain link and ornamental fencing, motorized access gate; temporary trail relocation; traffic control; and rock surface landscaping. In conjunction with the construction of the new pump station, new valve vaults will be constructed to improve connections to the Morris Reservoir at the inlet and outlet. These connections are crucial to the functioning of the new pump station. Additional improvements are planned along the existing 18-inch City Creek Water Treatment Plant transmission pipeline from the air valve at the high point down to 18th Ave. Other valve vault improvements will be constructed near the Ensign Downs Low Tank. These include replacing a butterfly valve in the tank valve vault and constructing a new hydraulic control valve vault near Oak Forest Road and Capitol Oaks Lane. Upon successful completion, commissioning, and testing of new facilities, the existing pump station will be decommissioned components inside the building will be demolished/salvaged and removed, and the space will be renovated according to the Contract Drawings. Renovations will include slip lining the existing sewer lateral to 18th Ave.
Engineering Estimate: $9,441,000.00
