Kiewit ranks as the country's top contractor in the delivery of water supply projects, according to Engineering News-Record magazine. We've built major roller-compacted concrete, earth-fill and rock-fill dams; reservoirs; water tunnels; and canals across North America. In addition, Kiewit is a leader in the development of transmission pipelines, aqueducts and water/wastewater treatment facilities.
Over the last 10 years, Kiewit has provided procurement, construction and start-up services for more than 280 public and private water supply projects totaling more than $6.3 billion in contract revenue.
The City of Bakersfield awarded Kiewit Pacific Co., a subsidiary of Kiewit Corporation, a $211 million project to upgrade the existing Bakersfield Wastewater Treatment Plant. To date, this project is the largest contract the City of Bakersfield has ever awarded.
This $20 million project involves replacing the existing sewage pump station with a new upsized 39 MGD pump station. Construction on the new pump station includes a below-grade wet-well and dry-well, and an above-ground electrical room.
This award-winning project allows migrating salmon and steelhead trout to bypass the Bonneville Dam and travel safely through the Columbia River. Kiewit Pacific Co. ultimately constructed a 3,000-ft.-long, high velocity concrete chute with 25-ft.-high walls to transport fish around the dam and through a new channel outfall.
This $61 million project involved the design and construction of a water transmission system. The success of the shutdown, tie-in, and restart was due to the project team's well planned coordination and communication with the local agencies and community.
East Dam is one of three dams constructed for the Metropolitan Water District of Southern California's Eastside Reservoir program. Holding more than 260 billion gallons of water, the reservoir will double Southern California's surface storage capacity. At 180-ft. high and 1,200-ft. wide at the base, East Dam is the longest of the three dams.
The $11 million project involved installing 7,000 linear feet of pipeline, a two-million-gallon concrete reservoir, a booster pump station, consisting of five vertical turbine pumps, water treatment facilities, a new arsenic treatment system and a well development. To increase the station’s water distribution pressure, crews constructed each zone with three 100-horsepower and two 75-horsepower vertical turbine pumps with variable frequency drives, which extend down 37 feet into a header, supplied with water from the bottom of the reservoir.
