Pipe Fitting on a Grand Scale

Energy Supply

Apr 27, 2011  Comment

Work has started at our Mayo B site to lay the more than 200 pieces of pipe needed to carry water between Wareham Lake and the new powerhouse, three kilometres away. Each piece of pipe, known as penstock, is more than 18 metres (60 feet) long, and more than three metres (10.5 feet) in diameter. The penstock was fabricated in China, shipped to Vancouver, and then trucked piece by piece to the Mayo site. Here are some photos of the process. Photo credit: www.archbould.com

Bottom photo is an interior shot of the penstock as it is being welded together and before it is buried underground.

It will likely take until late summer for all the penstock to be installed and buried.
