Built between 1887 and 1889 Potts Hill Reservoir No 1 stands before you. It’s a testament to Sydney’s ingenuity. This rectangular marvel is a key player in Sydney’s water story. Its earthen banks hold a puddled clay core. The inner faces are lined with sandstone masonry. Notice the evidence of repairs. The embankments have been strengthened over time. This shows the reservoir’s resilience.
Potts Hill Reservoir No 1 wasn’t just a reservoir. It was a vital part of the Upper Nepean Scheme. This scheme revolutionized Sydney’s water supply. Before this water came from sources like the Tank Stream. Those were far less reliable. The Upper Nepean Scheme provided a consistent and abundant supply. Potts Hill Reservoir No 1 played a crucial role in that. It acted as a service reservoir. This meant it handled daily fluctuations in demand. Imagine the pressure! This reservoir ensured that Sydneysiders had water when they needed it.
Potts Hill itself has a rich history. Long before the reservoir it was known as Irishtown. That name reflects the community that settled there. The name Yagoona replaced Irishtown later. This Aboriginal word means “now” or “today”. The area’s transformation from rural farmland to suburb is fascinating. The arrival of the reservoir changed everything. It transformed the landscape and the lives of people. The reservoir’s construction involved impressive feats of engineering. The sandstone lining is a testament to the techniques used.
The reservoir is more than just an engineering marvel. It’s a historical landmark. The surrounding landscape is equally compelling. Note the palm trees. They were planted as windbreaks. They also add to the beauty of the site. The bridges too tell a story. One was a rail bridge for coal delivery to the pumping station. These are all details which reflect the history of the site and its operational needs. Potts Hill Reservoir No 1 is a significant part of Sydney’s past and continues to serve the city today. It’s a reminder of the constant effort to provide clean water for a growing population. A truly remarkable piece of Sydney’s infrastructure. And a fascinating chapter in the city’s history.
