Western Outfall Main Sewer

The Western Outfall Main Sewer features three 1.83-meter diameter brick barrels encased in concrete, supported by substantial concrete arches across Wolli Creek.

Built between 1895 and 1898, this sewerage system prevented pollution in Sydney Harbour by redirecting waste through two main lines serving multiple suburban areas.

The engineering methods and materials used in constructing the brick barrels demonstrate the technical capabilities and infrastructure development of 19th-century Australia.

The sewer system extends through multiple suburbs including Strathfield, Burwood, and Ashfield, managing wastewater through an 804-meter-long concrete open trough design.

The structure incorporates three separate barrel channels that merge at the Premier Street Penstock Chamber before crossing waterways via an engineered aqueduct system.
