WATER/WASTEWATER
OUR MARKETS
We are a leader in all things water
Kiewit consistently ranks as one of the country's top contractors in the delivery of water and wastewater projects, according to Engineering News-Record (ENR). The 2015 ENR Sourcebook rankings list Kiewit as the No. 1 contractor for dams & reservoirs and water supply categories, as well as No. 2 for water treatment desalination lines, No. 3 for water transmission lines and No. 4 for sanitary and storm sewers. Kiewit’s water/wastewater portfolio includes major roller-compacted concrete, earth-fill and rock-fill dams; reservoirs; water tunnels; and canals across North America, as well as transmission pipelines, aqueducts and water/wastewater treatment facilities. Over the past 10 years, Kiewit provided procurement, construction and/or start-up services for 400 water/wastewater projects totaling more than $6.5 billion in contract revenue.
Gulf Intracoastal Waterway (GIWW) West Closure Complex
Belle Chasse, La.
The GIWW West Closure Complex is a $1 billion hurricane storm surge (flood) protection facility for the city of New Orleans and surrounding areas. This Early Contractor Involvement (ECI) contract included one of the world’s largest interior drainage pump stations and one of the nation’s largest navigable floodgates (225 feet). The pump station has 11 units and is capable of discharging storm water at a rate of 19,140 cubic feet per second.
Deer Valley Water Treatment Plant
Phoenix, Ariz.
The scope of work included demolition of the existing hopper bottom, metal roofed reservoir, the construction of a new 20 MG cast-in-place reservoir, installation of chemical feed piping, level sensors, transmitters and associated conduits and control wiring.
Somerton Wastewater Treatment Plant Expansion
Somerton, Ariz.
Kiewit was selected by the City of Somerton for the expansion of their Sequential Batch Reactor (SBR) Wastewater Treatment Plant (WWTP). Prior to the design commencing, Kiewit performed cost modeling and constructability reviews to aid in the determination if a Biological Nutrient Removal Process (BNR) design would be more beneficial than the original concept. Kiewit provided anticipated construction costs and schedules for the conversion of the existing SBRs to a BNR. Kiewit performed the same analysis in developing the cost and schedule for the construction of additional SBRs. These side by side comparisons allowed the selection of the best value expansion approach for the WWTP. The BNR approach was selected and increased the current .8 MGD to 1.8 MGD for an addition of .6 MGD in capacity from the original concept.
Union Hills Water Treatment Plant Rehabilitation
Phoenix, Ariz.
The Union Hills Water Treatment Plant Rehabilitation project involved the complete replacement and upgrade of half of the plant’s 5kV electrical feed, including construction of a new electrical building expansion and 2,500+ LF of new ductbank installation amidst numerous existing utilities. New electrical switchgear and motor control equipment were furnished to upgrade the plant’s finished water pump systems.
Permanent Canal Closures and Pumps (PCCP)
New Orleans, La.
The Permanent Canal Closures and Pumps project (PCCP) was a fixed-price, design-build project that provided a permanent, more sustainable solution for reducing the risk of a 100-year level storm surge entering the outfall canals throughout the city of New Orleans.
Yucca Mountain
Nye County, Nev.
A Kiewit-led joint venture excavated over 40,000 ft. of an 18- and 25-ft.-dia. tunnel to develop the Exploratory Studies Facility (ESF). The ESF was constructed to determine the suitability of storing high-level nuclear waste. A unique feature of the project was the use of a "mapping gantry" to provide safe access for project geologists and scientists during excavation.
Texas Street Pump Station
San Bernardino, Calif.
The project involved construction of a new pump station and 0.5 MG reservoir, de-chlorination facility, electrical ductbank, and roadway improvements.
Table Rock Auxiliary Spillway Phase 1
Branson, Mo.
By partnering with the U.S. Army Corps of Engineers, Kiewit finished this project four months ahead of schedule. Phase I involved excavating, blasting and preparing the spillway's foundation. Because blasting occurred beside the existing dam and near a heavily-traveled highway, expertise in controlled blasting and seismic monitoring was essential.
Olivenhain Pump Station
San Diego, Calif.
This $24 million project involved constructing a building to house three 2,500-HP pumps and their associated piping. The interconnecting pipeline outside the pump station was also included in the standard bid-build contract.
East Dam
Hemet, Calif.
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 doubles Southern California's surface storage capacity. At 180 feet high and 1,200 feet wide at the base, East Dam is the longest of the three dams.
