Tunnel Membrane in the Pressure Tunnel for the Sir Adam Beck Hydroelectric Generating Stations

The forces of the Niagara River have been used for more than 250 years now. In order to take advantage of the maximum drop in height, Sir Adam Beck planned a 20 km long channel in the early part of the 20th century. This diverted water from above the Falls and carried it to below the Niagara River’s rapids. The “Sir Adam Beck I” hydroelectric generating plant with a fall in height of 89 m began operating in 1922. Extensive expansions were undertaken during the 1950s. Since 1954 two tunnels have supplied the “Sir Adam Beck II” hydroelectric generating station with water.
