Upper Canal System

The Upper Canal System is a water supply network in New South Wales that extends across multiple kilometers and incorporates open channels, tunnels, and pipelines. This infrastructure transports water from the Nepean River to settlements using gravity, requiring no pumps to function.

The system was built in the 1880s to supply water to Sydney's growing population. Its completion represented a major step in securing the city with reliable water delivery.

The canal system shows how water flows from the river to reach homes and shapes the way people use the land. It forms part of the daily infrastructure that becomes visible when traveling through the region.

Access to the system is limited since it remains an active water supply facility under protection. Visitors can view parts of the structure from outside when traveling through the Middleton Grange area.

The system was built with remarkably precise slope, allowing water to flow without external energy sources. This achievement demonstrates the technical skill of engineers from that era.
