Wolli Creek Sewer Aqueduct, Sewerage aqueduct in Undercliffe, New South Wales, Australia.
Wolli Creek Sewer Aqueduct is a sewerage bridge spanning a waterway in Undercliffe with three large pipes supported by brick arch vaults and steel beams. The structure combines white glazed face bricks with sandstone cornices and uses both arched supports and steel framework to carry the pipes across the creek.
The aqueduct was built in 1895 by the NSW Public Works Department to expand the sewerage system serving western suburbs of Sydney. In 1929, an additional welded steel pipe was installed, reflecting advances in construction technology of that period.
The structure incorporates white glazed face bricks in English bond pattern and dressed sandstone cornices, reflecting the engineering standards of the late 1800s.
The structure is visible from nearby pathways and creek-side routes that offer good viewing opportunities from ground level. Access to the surrounding area is straightforward, though you may not be able to touch or examine the aqueduct itself closely.
The structure showcases an unusual blend of materials, with the original wrought iron pipes from 1895 still in place alongside the welded steel pipe added later. This side-by-side combination of two construction eras provides a rare window into how infrastructure technology evolved during early urban expansion.
