Description: Built by the Canadian Pacific Railway between 1912 and 1914, the aqueduct is a 3.2 km. (2 mi.) long reinforced concrete trestle with a maximum height of 9.5 m (64 ft.). The structure incorporates some 19,000 m3<\/sup> (25,000 yd3<\/sup>) of concrete and 1800 tonnes (2,000) tons of reinforcing steel. It was constructed over three summers by a crew of up to 300. The trestle supports a suspended shell designed to carry water east from Lake Newell. An inverted siphon transports the water under the Canadian Pacific Railway line. The Engineers responsible for the structural and hydraulic design were Hugh B. Muckleton and H. M Gibb. It was replaced by a canal in 1979.<\/p>\r\n\r\n\r\n\r\n

Historic Significance: The Brooks Aqueduct was constructed as part of an extensive irrigation project intended to make land in the south-eastern region of Alberta suitable for farming. The aqueduct is a significant civil engineering structure from both design and construction perspectives. At a time when reinforced concrete was not in wide use, its size, length, materials used, the volume of water carried and the siphon under the CPR line all presented unusual design problems. The hydrostatic catenary design of the flume minimized resistance to water flow.<\/p>\r\n\r\n\r\n\r\n
