No1 Pump Station

No 1 Pump Station at Mundaring Weir is one of Western Australia's most prominent heritage landmarks. The Goldfields Water Supply Scheme designed by CY O'Connor was originally built to transfer water from the Perth hills to the goldfields of Western Australia, a distance of 560 kilometres.

The scheme was opened in 1903 and part of it was still operating under steam power until 1970. No 1 Pump Station was the first of eight pump stations and an extensive four-year renovation project by the National Trust now makes No 1 Pump Station a showcase for the scheme.
