The Goldfields Pipeline Pipes

Mephan Ferguson’s innovative locking bar pipes were a bold and groundbreaking choice for the Goldfields Water Supply Scheme. At the time, most steel pipes were riveted, with each rivet hole presenting a potential leak and disrupting the smooth flow of water. Ferguson’s revolutionary locking bar system eliminated these vulnerabilities, creating stronger, more efficient pipes that maximized water flow.

The pipes were joined through a meticulous process called ‘caulking.’ This involved fitting a steel ring around the pipe ends, leaving a 6 mm gap. The space was first packed with rope, then sealed with molten lead, which was hammered into place as it cooled to create a watertight seal. In 1901, James Couston’s invention of a caulking machine streamlined this process even further.

The scale of the project was immense: more than 60,000 pipes, each measuring 762 mm in diameter and 8.5 metres long, were manufactured and laid. To ensure efficient water movement across the vast distance, the scheme was divided into eight sections, each with its own steam-powered pump station.

This innovative pipe design and the engineering foresight behind it played a crucial role in delivering water across hundreds of kilometers of dry landscape—a testament to human ingenuity and the transformative power of engineering.
