Pipe Fitting on a Grand Scale | Wednesday, April 27, 2011

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

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