The suburb Helena Valley is a few kilometres downstream of the dam. The dam was first constructed in the early 1970s, on the Helena River at

His company built twenty bridges along the north-eastern railway and another eight for the Clifton Hill line . Ferguson supplied 1,300 long tons (1,300 t) of wrought iron and cast iron for the building of
72-674: A factory near Midland Junction (now known simply as Midland ) to produce the other half. When built, the pipeline was the longest fresh-water pipeline in the world. The pipeline ran alongside the earlier route of the Eastern Railway and the Eastern Goldfields Railways for parts of its route, so that the railway service and the pipeline had an interdependence through the sparsely populated region between Southern Cross and Kalgoorlie. The scheme required significant infrastructure in power generation to support
96-494: A location on the southern boundary of the suburb of Darlington . By the 1980s and 1990s, the catchment and water quality saw a number of studies and reports. Into the 2000s, further research continued, and the upper parts of the catchment area were being considered as restricted activity zones. 31°56′31″S 116°04′35″E / 31.942083°S 116.076509°E / -31.942083; 116.076509 Goldfields Water Supply The Goldfields Water Supply Scheme

With most of the original stations being steam-driven, a ready supply of timber was needed to fire the boilers. Hence the pipeline route was closely aligned with the Eastern Railway . To enhance the reliability of the system, each pumping station was designed and constructed with a spare pumping unit. Due to pressure requirements related to
144-473: Is a pipeline and dam project that delivers potable water from Mundaring Weir in Perth to communities in Western Australia 's Eastern Goldfields , particularly Coolgardie and Kalgoorlie . The project was commissioned in 1896 and completed in 1903. The pipeline continues to operate today, supplying water to over 100,000 people in over 33,000 households as well as mines, farms and other enterprises. During

Note – the material on the scheme is in its entirety a significant collection, and although the Water Authority might hold a comprehensive bibliography, it has not been published.

192-823: The Newport Workshops . In 1885 the Government of Victoria decided to change the Melbourne water supply pipes from wrought iron to cast iron. Ferguson won the contracts to supply the new pipe. To enable this expansion he bought the Glasgow Iron works in West Melbourne . With the Carlton Foundry, Ferguson now employed over 300 people. He soon after established a new foundry in Footscray . Ferguson gained international attention by winning

Hartley , won the Margaret Medcalf award of the State Records Office of Western Australia in 2008. Lower Helena Pipehead Dam is now also used to supply water to the Goldfields region. Water from the dam is currently pumped back into Mundaring Weir. The scheme
240-712: The Goldfields from a dam on the Helena River near Mundaring in Perth. The scheme consisted of three key elements – the Mundaring Weir, which dammed the Helena River in the Darling Scarp creating the Helena River Reservoir; a 760 millimetres (30 in) diameter steel pipe which ran from the dam to Kalgoorlie 530 kilometres (330 mi) away; and a series of eight pumping stations and two small holding dams to control pressures and to lift
264-494: The contract to supply 530 km (360 mi) of 760 mm (30 in) steel main for the Goldfields Water Supply Scheme . The pipes used Ferguson's patented rivetless pipe or locking bar, the design of which improved the water flow. A stylised drawing of the design is now used to indicate places of interest along the pipeline. To manufacture the pipe, Ferguson imported sheet steel from England and

Prior to the scheme, water condensers, irregular rain, and water trains were part of the range of sources. Railway dams were essential for water to supply locomotives to travel to
312-618: The goldfields. Throughout the 1890s, water availability issues in Coolgardie and in the Kalgoorlie-Boulder region were causing concern. On 16 July 1896, the Premier of Western Australia , Sir John Forrest introduced to Western Australian Parliament a bill to authorise the raising of a loan of £2.5 million to construct the scheme: the pipeline would convey 23,000 kilolitres (5,100,000 imp gal) of water per day to
336-576: The pipeline was utilised for a number of country towns adjacent to its route, and also into the Great Southern region . The Public Works Department started this project in the 1950s following the raising of the weir wall in the early 1950s and it completed this work in 1961. The scheme was "interpreted" by the National Trust of Western Australia in its Golden Pipeline Project , which created guide books, web sites, and tourist trails along
360-431: The pumping stations. Communities oriented to the maintenance of the pipeline and pumping stations grew up along the route. With improved power supplies and modern machinery and automation, the scheme now has more unattended pumping stations operated by fewer people. Construction of the dam started in 1898. When completed in 1902 it was claimed to be the highest overflow dam in the world. Shortly after World War II, raising

The pipes were manufactured locally from flat steel sheets imported from Germany and the United States. Mephan Ferguson was awarded the first manufacturing contract and built a fabrication plant at Falkirk (now known as the Perth suburb of Maylands ) to produce half of the 60,000 pipes required.

The Trust achieved the responsibility in an agreement with the Water Corporation in 1998. Most of the material was developed between 2001 and 2003. In 2007 two items were produced that were overviews of the scheme: The history of the construction of the Goldfields Water Supply Scheme was detailed in

Lady Forrest officially started the pumping machinery at Pumping Station Number One (Mundaring) on 22 January, and on 24 January 1903 water flowed into the Mount Charlotte Reservoir at Kalgoorlie. O'Connor's engineer-in-chief, C. S. R. Palmer took over the project after his death, seeing it through to its successful completion. The government conducted an inquiry into
456-467: The slope of the pipeline, stations one to four required two pumping units to be in operation. Stations five to eight only required one operating pump, due to a lower rise in height between those stations. James Simpson and Co supplied 3,500 tonnes of equipment in 5,000 separate boxes for the construction of the pumping sets. All the original pumping stations were powered by steam. Branch mains, or extensions, were started as early as 1907. Water from

The Public Works Department originally constructed and ran the railway from the Mundaring railway station for the purpose of delivering materials to the construction site. The Western Australian Government Railways took over the railway operation. It ceased operation in 1952, and the connecting railway line at Mundaring closed in 1954. The distance

Although supported by Premier Forrest, O'Connor had to deal with widespread criticism and derision from members of the Western Australian Parliament as well as the local press based on a belief that the scope of the engineering task was too great and that it would never work. There

Sunday Times editor Frederick Vosper – who was also a politician, ran a personal attack on O'Connor's integrity and ability through the paper. Timing was critical, Forrest as a supporter had moved into Federal politics, and the new Premier George Leake had long been an opponent of

He immigrated with his parents to Melbourne in the colony of Victoria in Australia arriving in 1854. In 1857 Ferguson was indentured as an apprentice blacksmith to John Price of Ballarat . Around 1874 Ferguson established

To rise the almost 400 metres (1,300 ft) in altitude, issues with friction meant that a head of 800 metres (2,600 ft) had to be achieved. O'Connor had eight pumping stations that each pumped the water to the next of the receiving tanks in his plans. Leakages were noted early; by the early 1930s, 1,700,000 kilolitres (370,000,000 imp gal) of water per year –
