Morgan Whyalla pipeline
The Morgan – Whyalla pipeline was an engineering project undertaken by the South Australian Government in 1940 to bring water from Morgan on the River Murray to the industrial city of Whyalla. A second pipeline, by a divergent route, was laid in the 1960s.
==History==
In 1937 Premier Butler of South Australia negotiated with Broken Hill Proprietary Company to erect a blast furnace at Whyalla to process iron ore from Iron Knob using brown coal from Leigh Creek. Lack of sufficient fresh water was an obstacle, To this end Butler pushed through enabling legislation and sent engineers to Western Australia to inspect their achievements in above-ground pipelines, notably the Goldfields pipeline engineered by C. Y. O'Connor. In 1938 Premier Playford increased the demands on BHP, and came to an agreement with Essington Lewis that if the company were to install a tinplate manufacturing plant, the State would supply the water infrastructure. Playford reckoned on the proposed pipeline also supplying the needs of Commonwealth Railways at Port Augusta for their Indian Pacific and Ghan railways. Prime Minister Lyons agreed to help South Australia with a development loan.
In 1939 Lyons died and was replaced by Menzies; shortly after, World War II broke out and Menzies joined with Britain in declaring war on Germany. Under the changed circumstances, Playford renegotiated the deal in terms of shipbuilding rather than tinplate manufacture. In 1940 the Commonwealth Water Agreement Ratification Act was passed, complementary legislation passed through South Australia's parliament and South Australia's Engineering and Water Supply Department was given the task of getting the job done, under considerable pressure from the War Department, and with reduced manpower and materials due to exigencies of wartime. The first stage, from Whyalla to the Baroota reservoir, was rushed through to help supply water for shipping. The whole route, using continuously welded steel pipe (supplied by Hume Pipe Company), four pumping stations and 127 concrete storage tanks, was completed in 1944, just in time to alleviate a serious drought that had hit the mid-North of South Australia. The pipeline was officially opened by the Governor of South Australia, Sir Charles Malcolm Barclay-Harvey in 1945.
