What Makes Revesby's Water Unique?
Local geology and source profile
Revesby's drinking water is supplied by Sydney Water, treated at the Prospect Water Filtration Plant drawing predominantly from Warragamba Dam (Nepean River system) for the Canterbury-Bankstown LGA southern Sydney distribution in New South Wales. Water hardness in Revesby is measured at 43.5 mg/L — classified as soft — far below the Australian Drinking Water Guidelines (ADWG) aesthetic guideline of 200 mg/L published by NHMRC. Revesby — a family-oriented residential suburb on the Georges River in the southern Canterbury-Bankstown LGA, known for the Revesby Workers' Club, the Revesby Station shopping strip, and the peaceful Georges River Parklands along the suburb's eastern boundary — receives near-soft supply in remarkable contrast to the hard Yagoona (168 mg/L) and moderately hard Lakemba (135 mg/L) in the same Canterbury-Bankstown LGA, confirming dramatic supply blend variation across the LGA's distribution network.
Revesby's soft supply reflects the predominantly Warragamba Dam contribution at this southern Canterbury-Bankstown Prospect distribution sub-zone, with minimal Hawkesbury-Nepean blending. Warragamba Dam collects rainfall from the Blue Mountains sandstone plateau and Kanangra–Boyd granite uplands — chemically resistant terrain contributing negligible dissolved minerals. The Revesby southern Canterbury-Bankstown distribution sub-zone at 43.5 mg/L and TDS 74.2 mg/L receives a proportionally high Warragamba fraction through supply routing that bypasses the heavier Hawkesbury-Nepean component reaching the northern Canterbury-Bankstown sub-zones.
Revesby residents enjoy low limescale accumulation on taps, in kettles, and around shower fittings — descaling every two to three months is typically adequate. Hot water systems accumulate minimal scale. The low lead reading (0.002 mg/L) is reassuring. Sydney Water provides water quality information at sydneywater.com.au, with all ADWG health standards consistently met. Revesby's Georges River residential community and the Revesby Workers' Club precinct benefit from this soft, clean supply.
Geology & Source: Supplied by Sydney Water via the Prospect Water Filtration Plant drawing predominantly from Warragamba Dam — the Revesby Canterbury-Bankstown LGA southern supply carries soft water at 43.5 mg/L with low TDS of 74.2 mg/L, reflecting a predominantly Warragamba-dominant supply blend with minimal Hawkesbury-Nepean component, in stark contrast to the hard Yagoona (168 mg/L) in the same Canterbury-Bankstown LGA.
