Canning Tunnel : ウィキペディア英語版
Canning Tunnel
The Canning Tunnel was constructed between 1973 and 1975 to link Canning Dam to Perth's Integrated Water Supply System.〔(History of the Canning Contour Channel )〕 It was built to replace the Canning Contour Channel which was a depression era public works project of the 1940s and constructed in conjunction with the opening of the dam.
The tunnel originates just west of Canning Dam and runs for approximately through the granite Darling Scarp to the western portal trunk main in Soldiers Road about South of the Brookton Highway intersection. It measures x 2.7 m. A separate pipeline from Canning Dam remains. The tunnel is more than below ground level at its deepest point.
110 men were employed in the first year of construction after which the workforce reduced to 60. The tunnel was built at a cost of $3.5 million and was officially opened in 1975 by Hon. D. H. O'Neil MLA the Minister for Works and Housing on Friday 17 January 1975.
The Canning Contour Channel was maintained and partially operated for two years after the tunnel's opening as a precautionary measure.〔
