Bankstown Reservoir, Water tower in Bankstown, Australia

Bankstown Reservoir is a water tower in Bankstown, New South Wales, with a circular tank supported by 36 concrete pillars. Decorative arches circle the structure, and the entire tower stands approximately 86 meters above sea level.

Construction of the reservoir began in October 1918 to relieve pressure on the Ashfield Reservoir and avoid pumping from Ryde. The concrete was mixed on site using a portable steam engine, and sandstone came from a quarry at Potts Hill. Hand rendering of the tank began in February 1920, and the reservoir was completed that year. It was the largest elevated reinforced concrete reservoir in Australia at the time.

The structure takes its name from the suburb where it stands and has become a recognizable landmark in the local landscape. The decorative arches surrounding the concrete pillars reflect the craftsmanship invested in early engineering projects of this scale.

The tower is visible from the street and located in a residential area accessible by public transportation. Visitors should note that the structure itself is not open to enter, but it serves as a distinctive landmark from nearby streets.

Before the reservoir, the hilltop was a gallows site: Patrick Sullivan and James Moran, of Sullivan's gang, were hanged there on 18 October 1826 after causing a stir in the Bathurst district. The hanging ground lay along the bushrangers' route on Liverpool Road. The reservoir's rooftop walkway, reached by a footbridge through the tank, stands 86 metres above sea level.
