Water Intake, Oak Creek Power Plant, Wisconsin, USA.  

As part of the Oak Creek Power Plant Expansion, Bechtel built a deep rock tunnel under Lake Michigan forming the water intake to the Oak Creek Power Generating Station on the west of the lake.  The 28-foot (8.5-meter) diameter 1.7 miles (2.8 kilometers) long tunnel was excavated by a Tunnel Boring Machine under the lake terminating in 24 submerged high-capacity wedge-wire screens. The screens protect the fish and other aquatic life within the lake by reducing the water approach velocity with their large surface area.  The onshore reach of the tunnel delivers 1,650 cubic feet per second (47 cubic meters per second) of water to the new pump house. 

Tinto Alcan Backup Tunnel, Canada.

Work includes drilling and blasting 883,000 cubic feet (25,000 cubic meters) of solid granite for five separate tunnels.

Rail Tunnels, London, UK.  

Bechtel is constructing a new tunnel beneath central London, building nine train stations, rebuilding or overhauling other stations, and upgrading existing track for the Crossrail project. This project includes 13 miles (21 kilometers) of tunnel through ground that's honeycombed with networks of sewer lines, water, and gas mains; foundations of buildings; and London Underground tunnels dating to the 1860s.

Pipelines

Bechtel has delivered more than 50,000 miles (80,00 kilometers)  of pipeline—including more than 1,759 miles (2,816 kilometers) of water pipelines. 

On our Escondida Water Supply project 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 in Chile. The water will travel more than 112 miles—from the ocean and through the desert—to it's destination 10,500 feet above sea level in the Andes mountains.
