No 1 Pumping Station

No 1 Pump Station

The No 1 Pumping Station can be found at the base of the Mundaring weir. It was built in 1901 as part of the Goldfields Water Supply Scheme. It was the first of eight steam pump stations found along the 560kms of pipeline to Kalgoorlie. Like the other 7, it is no longer in service.

No 1 Pumping Station History

The red brick pumping station was built in industrial Federation Warehouse style. The pumping machinery was contracted to James Simpson and Company of London. The engines and pumps rested on granite bedrock supported by brick piers.

The boilers were originally designed to run on coal but were later adapted to be wood fired. Interestingly, from 1902 to 1926 over 3,750 acres of jarrah had to be cut to supply the No 1 pump.


The 41.5m chimney stack was required to provide a draft to keep the boilers working. The chimney is about 4m in diameter at the base and tapers up to about 2m.

The total cost of all 8 pumping stations at the time was £ 436,000.

As soon as the weir wall was completed the pumping began. Lady Forrest had the privilege in turning on the machinery at No 1 Pumping Station on the 22nd of January 1903.

In 1954 the No 1 and No 2 Pumping Stations were replaced with electric stations, leaving them pretty much abandoned. However, in 1962 the pumping stations were given a new lease on life  when the Western Australian Tourist Development Authority turned it into the C.Y. O’Connor Museum.

In 1998 the Water Corporation of WA and the National Trust of Australia (WA) came to an agreement that all heritage sites and assets associated with the Goldfields Water Supply Scheme would be managed by the National Trust. As a result in 2000 the museum was closed and the building renamed the No 1 Pumping Station once more. The station was redeveloped and is now  a public recreational and educational venue.

The pipeline still pumps about 90 million litres of water each day. It is also the world’s longest freshwater pipeline and hasn’t stopped pumping water for 115 years.
