Annandale Sewer Aqueducts

These 1896 Aqueducts were the first structures in Australia to incorporate Monier Arches and were designed by W. Baltzer to carry the Northern (NT) sewer main across Johnstone's and White's Creeks. After the choice of this new form of construction had been investigated by a Royal Commission, the contractor - Carter, Gummow and Forest - had to lodge a large sureity and guarantee maintenance for three years. The success of the work pioneered the introduction of reinforced concrete to Australia.
