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.
A Kiewit-led joint venture was selected in December 1997 to construct a key component of the new $2.2-billion water delivery and treatment system for the Las Vegas valley. This $83-million project involved constructing a 12-ft.-dia. intake shaft positioned 240 ft. below Lake Mead's surface, capable of handling 600 million gallons of water per day.
This $13 million project involved construction of two new pump stations, which included all structural, architectural, mechanical, and electrical requirements. At the request of the local community, the project team worked together with the owner to redesign and offer solutions to ultimately satisfy the local concerns regarding the aesthetics, which resulted in a Tuscan style building exterior. This project required extensive coordination with local residents, which included door-to-door contact, meetings, and flyers within the community.
Kiewit Pacific Co. is constructing the existing surge shaft in two phases to install 550 vertical feet steel pipe 96 inches in diameter. The team engineered and performed the water treatment, collection system and road improvements.
Lake Mead Constructors was selected to construct this $146 million 150-mgd water treatment plant. The project later expanded to include an additional $31 million 150-mgd phase. During construction, the project team took steps to minimize impacts to the surrounding community by applying several aesthetic enhancements and establishing an on-site concrete batch plant to reduce truck traffic.
The $71 million Robert B. Diemer Filtration Plant project was to establish a seismically stable foundation for a new ozone generation facility. Before any production work could begin, a large amount of demolition work needed to be completed, including the existing maintenance building, fueling station, asphalt parking area and duct bank runs.
The $87 million Sacramento River Water Treatment Plant expansion involves increasing the current facility's capacity by 60% to 160 million gallons per day. One of two plants that supply all of the drinking water for the City of Sacramento, the project will be finished in early 2005.
This $70 million project called for construction of the San Vicente Pump Station with three sets of 7,000 hp pumps and motors, surge control facility, and pipelines connecting the San Vicente Pump Station, San Vicente Pipeline, Moreno Lakeside Pipeline, and the San Vicente Interconnect Pipeline. This project was part of the San Diego County Water Authority's Emergency Storage Project and received the American Society of Civil Engineers (ASCE) Outstanding Water, Wastewater & Reuse Project award in 2010.
This $89 million project involved the construction of a 15-million-gallon-per-day water reclamation plant and process facilities for the 2.9 million people in the San Diego area. Just months after award, the client doubled the plant's capacity and selected the on-site Kiewit Pacific Co. team to handle the additional work.
Kiewit Pacific Co. is constructing updates to the Waterman Treatment Plant originally constructed in 1974. The improvements will increase the plant's capacity from 15 million gallons per day to 30 million gallons per day. In an effort to modernize the plant, many of its facilities will be completely or partially torn down and replaced.
