context_page_description: The Boothtown Aqueduct is a heritage-listed 19th-century water bridge in Greystanes, Sydney, New South Wales, Australia. Established in 1888, the aqueduct was built to cross a valley to carry water from Prospect Reservoir to residents of Greater Western Sydney.
  Part of the Lower Prospect Canal Reserve, the aqueduct was the longest continuous concrete work of its kind in Australia in the late 19th century and early 20th century. It was listed in November 1991 in the New South Wales Heritage Database.
  The aqueduct was constructed as a part of the Upper Nepean Scheme to convey water from the new Prospect reservoir to the new Potts Hill reservoir.
context_section_description: The bridge is made up of 22 arches made of brick, each of 10.16 m (33 ft 4 in) span with a 9.1 m (30 ft) clear span of brick with sandstone springers and was named after John Booth. The aqueduct has a look of an architectural puzzle, expanding and decreasing in size, with the arches aligning differently with each change of aspect. Today, the concrete legs have weathered look, stained by rain and weather. Some vandalism is present on the bridge's arches.
  The towers are made of rendered brick, embellished with cement-furnished castellation and doorways that are lancet-arched. The aqueduct was blocked with concrete plugs to divert water into the tube and into a large new concrete pipe. The tube inlets were built as ornate fortified towers with steel trash racks and sluice gates to control the water flow. Fairly decorative features are integrated into the brickwork, such as dentilation, pilasters to each arch and string courses of round cast bricks. The side walls are secured by tie rods.
