Buckman Direct Diversion Project

Santa Fe, NM

A joint venture with CH2M Hill, the Buckman Direct Diversion Project will create a diversified and more dependable water system to support the growing Santa Fe region.

In addition to providing regional infrastructure for the Rio Grande surface water diversion system, the Buckman facilities comprise raw water transmission, a new water treatment plant, and a means for distributing finished water to the existing city system. Existing well fields can rest during spring run-off or wet years, then be brought “online” during periods of drought or poor surface water quality.

Elledge Wasterwater Treatment Plant

Winston-Salem, NC

In December 2008, a diverse team led by WSCI began mass excavation for the $51.9-million Archie Elledge Wastewater Treatment Plant expansion.

The thrust of the project is replacing plant systems including a new headworks facility, four new primary clarifiers, three new backup power generators, and a new central control building that uses SCADA systems. Additionally, Western Summit is constructing and installing new yard and site drainage systems, pump stations, roadways, and landscaping.

Middle Oconee Water Reclamation Facility

Clarke County, GA

The Middle Oconee WRF is one of a trio of upgrades that comprise the largest public works project in Athens / Clarke County history. Responsible for collecting millions of gallons of wastewater from residents, businesses and industries, the facility ensures that the water is properly treated and returned safely to area waterways. This expansion will increase plant capacity from 2 MGD to 10 MGD, and add state-of-the-art technology that will improve the level of treatment.

City of Brighton GID Phase 1 Utility Project

Brighton, CO

With a contract value of nearly $5.5 million, this project will expand Brighton's infrastructure in support of its growing population. Phase 1 highlights include construction of 27,000 linear feet of 24"-diameter water line, 21,000 linear feet of 24"-diameter sewer line, a lift station, and four tunnels. The water lines are installed eight feet deep, while the sewer lines are more than twenty feet below ground.

Prairie Waters Projects

Aurora, CO

Water Purification Facility
At $192 million, and located on 80 acres, Prairie Waters is the largest project ever undertaken by Western Summit without a joint venture partner. When finished, this state-of-the-art water purification facility will increase water supply by 20 percent, or about 3.3 billion gallons per year.

One of the most environmentally sustainable water supply systems in the West, Prairie Waters will use water from the South Platte River, naturally purifying it using a unique process that creates no waste to discharge. Up to 50 million gallons of water per day will be treated and then blended with flow from the nearby Aurora Reservoir.

The plant will be supported by more than 39,000 linear feet of piping, ranging in size from 4 inches to 72 inches in diameter, and buried up to 45 feet deep.

Pump Station
One unique aspect of the project is a contract worth $50 million that has required simultaneous construction of three separate pump stations. From a piping perspective, this contract alone has required more than 36,000 linear feet of pipe, ranging in diameter from 4 to 90 inches.

Otay Water Treatment Plant Expansion

Chula Vista, CA

WSCI’s eleventh project for the City of San Diego, this $24.7 million, two-phase upgrade will create a state-of-the-art facility that meets or exceeds federal and state drinking water regulations. When complete, the plant will provide 34 MGD of potable water to customers in three of the growing region’s major water service areas.

To minimize impact to overall ongoing plant operations, WSCI has used careful planning and "common" plant shutdowns that accommodate multiple work activities.
