Water Pipelines

These pipelines transports water from Pipehead to the Potts Hill Pumping Station. Pipehead receives water from Prospect Reservoir in western Sydney. (I added a little glow to the image.)

Here are some heritage details of the pipeline from the Sydney Water Website; "The Pipehead to Potts Hill Water Supply consists of three pipelines built between 1888 and 1925. In particular, Pipeline No.1 commissioned in 1888 is especially significant, as this was the first link between Pipehead (at Guildford) and the Potts Hill No.1 Reservoir, the scheme's major service reservoir for the gravitational supply of Sydney''s water. Now, over 100 years since the Upper Nepean Scheme was commissioned, the pipelines have not become obsolete, but by virtue of boosters, are still key components of Sydney's water supply system. In addition, the pipelines display superb late 19th century hydraulic construction techniques which were state-of-the-art technology of the time in Australia. Also, the three pipelines laid side by side illustrate the advancements in major pipeline construction over a span of some 37 years. Pipeline No.1 (1888) was constructed from wrought iron, Pipeline No.2 (1900) from mild steel and Pipeline No.3 (1925) from electrically welded steel plates. Finally, it was the changeover from open canal to No.1 Pipeline that gave Pipehead it's name, further adding to the significance of the pipelines. The site is now arguably the most important operations and control centre for Sydney's water supply system. The pipes are a visual feature of the landscape along which they run. The physical curtilage of the Pipehead to Potts Hill Pipelines extends to the boundary of Sydney Water Corporation land along the route of the pipelines.
