What did Romans ever do for Sydney? Aqueducts, gravity carried water

hiking along the former Lower Canal, where the aqueduct spans a valley.

There are about a dozen operating aqueducts in Greater Sydney, many carrying sewage. They include Wolli Creek, White Creek, Mosman and Cooks River. An aqueduct, sometimes called a water bridge, carries water; a viaduct carries traffic.But in this case, engineers looked to the late 19th century because they needed to get water over the existing pit, without spilling into it, exacerbating the risk of flooding in the area.

“What is brilliant about the Upper Nepean scheme was how the water travels by nothing more than gravity to Circular Quay,” said Bennett.​Credit:WaterNSW says the aqueduct was a crucial part of the city’s 150-year-old Upper and Lower Nepean system of canals and aqueducts to deliver water to most of Sydney from the Southern Highlands. using gravity.

The Upper Canal still works today. But after structural failures in the 1890s, in 1907 the aqueduct, then the longest continuous concrete work of its kind in Australia, was replaced by a three-metre wide inverted concrete syphon. The Lower Canal was decommissioned after a pipeline was completed in the 1990s, and the bush reserve surrounding the canal opened to the public in 2003 as a cycleway.

While we are talking, a cyclist stops us to warn of two large black snakes lying across the path, one at the 2200-metre point and the other a further 2000 metres on.
