St.Margaret’s Bay Hydro-electricity System, Nova Scotia

The Penstocks which carry the water from the head pond are large pipes of up to 11 feet in diameter.

The Original Penstocks were made from wooden tongue and groove staves held together with metal bands and sealed on the inside with pitch, the same technology as wooden barrels in that the water pressure inside the penstock forces the staves against the meta bands keeping it tight.

Original Wooden Penstock

The St.Margaret’s Bay  hydro-electricity  system was the first in Canada to use fibreglass penstocks

The penstock from Coon Lake was replaced with polypropylene in 2010 although the penstock is buried its position can be seen here
