Two original 19th-century engineering reports that shed new insight into Western Australia’s mammoth Golden Heritage Pipeline have been rediscovered by water engineering consultancy Binnies, an RSK Australia company. Binnies has donated the reports to Water Corporation to ensure the historical documents take their rightful place in Australia’s water heritage.
The 566 km Golden Heritage Pipeline was designed to bring a crucial water supply from Perth’s Mundaring Weir to the arid eastern Goldfields region during the Gold Rush. Designed by WA’s first Engineer in Chief CY O’Connor and built from 1898-1903, it was regarded as an engineering wonder, with many industry experts then doubting it could carry water over the distance.
Today, Western Australia’s Water Corporation operates and maintains the pipeline. CEO Pat Donovan said, “This is a fascinating discovery that adds another layer to our understanding of just how complex it was to build what was, at the time, the longest water pipeline in the world.
“Today, the Goldfields Pipeline remains a vital piece of infrastructure, delivering drinking water to more than 100,000 people across the Goldfields and agricultural regions. We’re extremely grateful to Binnies for sharing these reports, and we’ll ensure they’re safely preserved as an important reminder of this iconic piece of WA’s history.”
Binnies Australia Managing Director Glen Hardy says: “At Binnies, we were delighted when a former senior executive recently found the reports in an attic. Prepared under the direction of Binnies founder and world-renowned engineer Sir Alexander Binnie, the rediscovered reports are an 1897 feasibility study and a follow-up corrosion investigation from 1909.
Their rediscovery reminds us of Binnies’ important role in Australia overcoming water scarcity during a historically significant period. Given the Australian Water Association’s focus on ‘Our water, our tomorrow’, we must consider our shared responsibility for water security and collective future. We are proud to have contributed to the nation’s water engineering legacy, and will continue supporting Australia’s water future through the projects we deliver today.”
Both reports were commissioned by the WA Government and informed the pipeline’s final design and ‘as built’ condition. The feasibility study assessed the pipeline’s technical feasibility – comparing its design with engineering works in Britain and Europe – and advised on materials, pipe design, pumping arrangements, valve systems and corrosion prevention needed to pump water along what was the world’s longest freshwater pipeline at the time. It concluded that delivering 22.7 megalitres per day uphill – with a climb of 390 metres over the Darling Range – was achievable if leakage and corrosion were controlled.
The second report identified corrosion as a serious threat to the pipeline’s success over time. It presented the results of experiments that showed how different water types, temperatures, coatings and exposure periods affect the corrosion of wrought-iron and steel plates. Its recommendations included internal protective coatings, coated plates and monitoring of water quality – practices that have informed the way water infrastructure is designed and monitoring to this day.
It is fitting that the reports will be held by the Water Corporation, which displays sections of the Golden Pipeline in its Perth, WA offices. When presenting the reports to Water Corporation, Glen said: “We want these historical documents preserved for future generations of engineers, historians and local communities.”
Binnies has re‑established its presence in the Kalgoorlie region after 128 years, collaborating with fellow RSK company ADENCO to deliver critical water infrastructure.
