We help our industrial customers get reliable and sustainable access to water, without negatively impacting local community supplies.
Industrial water supply, conveyance and treatment solutions
- Water planning
- Transmission and conveyance
In Chile, we are creating a first-of-a-kind water system that will desalinate and deliver sustainable, fresh water to the world's largest copper mine. The water will travel more than 112 miles (180-kilometers)—from the ocean and through the desert—to its destination 10,500 feet (3,200 meters) above sea level in the Andes mountains.
The Escondida Water Supply project team is constructing a new seawater desalination plant, which will be linked to the Escondida mine site in the Andes by two 112-mile (180-kilometer), 42-inch- (107-centimeter-) diameter lined pipelines. Four high-pressure pumping stations will move water east from the port across the Atacama Desert and up to a reservoir at the mine,10,500 feet (3,200 meters) above sea level. In addition, we will deliver 75 miles (120 kilometers) of new 220-kilovolt transmission line, build three new substations, and expand four existing substations to power the system.
TInto Alcan Backup Tunnel, Canada
We completed Phase 1 of a project to connect two tunnels to service the Kemano powerhouse, a hydroelectric power station situated 75 km southeast of Kitimat in the province of British Columbia in Canada. The powerhouse provides 896 megawatts of power to the Kitimat Aluminium Smelter. The new tunnel system will serve as backup in case of a catastrophic event, such as a collapse, and will permit inspection and maintenance of tunnels without a shutdown of power production. Work included:
- Drilling and blasting 883,000 cubic feet (25,000 cubic meters) of solid granite for five separate tunnels
- Installing 11-foot (3.4-meter) diameter steel pipe liner with annular space backfilled with 282,517 cubic feet (8,000 cubic meters) of concrete
- Excavating 176,573 cubic feet (5,000 cubic meters) of an undergound guard valve chamber
- Procuring, fabricating, transporting, and installing six 11-foot (3.4-meter) diameter butterfly valves in underground chambers
Bechtel has managed the Jubail project, in the Eastern Province of the Kingdom of Saudi Arabia, since it began in the mid-1970s. In 2004, the Royal Commission for Jubail and Yanbu asked Bechtel to manage Jubail II, a 20,590-acre (8,300-hectare) expansion of the city’s industrial and residential areas. Today, Jubail is Saudi Arabia’s industrial center, contributing 7 percent of the country’s gross domestic product.
Bechtel has provided engineering, procurement and construction management services for six desalination plants (both SWRO and multistage flash distillation) providing over 428,000 m3/day of water for municipal and industrial use. In addition to these works we have delivered massive sea water cooling systems, canals, pump stations, waste water treatment facilities, and power supply (over 2,000MW).
