Kiewit Southern Co. was awarded the $11 million project to design and construct the Pembroke Pump Station. The team constructed an at-grade precast panel pump station, four 40-cubic-feet-per-second pumps with 30-inch-diameter expansion joints, back-flow gates and butterfly valves that are connected to a 64-inch-diameter steel header pipe.
The $9.5 million rehabilitation project included the complete removal and rehabilitation of seven horizontal, axial flow pumps. For the Pump Stations S7 and S8 project, Kiewit also had to re-machine the propellers and replace bearings, reconfigure the pumps basins, and a telemetry package.
Kiewit designed and constructed the largest most technologically advanced and energy-efficient seawater desalination plant in the nation. From the SWRO facility with pumping station and produced water storage to the 10-mile 54-in high-pressure welded steel conveyance pipeline; Kiewit also managed the seamless integration of the 50 MGD plant to the distribution system that included 9 jack and bore crossings, 900+ existing utility crossings, a 1,750 LF tunnel, and 42 manways.
For the 3 MGD Charles E. Meyer Desalination Plant, Kiewit led BOP design and construction of the projects facilities, structures and infrastructure. The revitalized plant and overall system uses state-of-the-art technology and incorporates design and construction practices – in all facilities and systems – to reduce electrical demand and environmental impacts, while providing a critical water supply for the City.
The largest brackish water desalination plant in North America has the capacity of 27.5 MGD to meet the needs of both Ft. Bliss and El Paso Water Utilities. With the constraints of a 22-month schedule from notice to proceed to substantial completion, Kiewit performed all structural concrete work, set all embed items for mechanical equipment and structural steel, installed pumps and piping, RO skids chemical systems and equipment, and performed start up and commissioning.
