Figtree Water Hardness & Quality Report (2026)

Figtree, located in the Wollongong area of New South Wales, receives its bulk water supply from WaterNSW and Sydney Water. The primary source is surface water drawn from Warragamba Dam, with additional contributions from other Sydney catchment reservoirs such as Woronora Dam and Avon Dam. Water treatment, including conventional filtration, disinfection, and fluoridation, is carried out at major facilities like the Prospect Water Filtration Plant before the water is distributed to suburbs in the Illawarra region, including Figtree. The catchment area for Warragamba stretches across the Blue Mountains and Southern Highlands.

The geology underlying the Warragamba catchment is dominated by Triassic-era Hawkesbury Sandstone and Narrabeen Group shales. These rock types are predominantly siliceous and sedimentary, forming a watershed that yields water with very low mineral dissolution. Because there are no significant limestone or dolomite deposits in the region, the water flowing through these inert sandstones picks up minimal calcium and magnesium. This geological makeup is the reason for the consistently soft water quality delivered to Figtree and other areas served by the Sydney water supply.

Because the water is soft, homeowners in Figtree won't experience the common issues associated with hard water, such as limescale buildup on plumbing fixtures, kettles, or inside appliances like dishwashers and water heaters. You won't need to worry about frequent descaling maintenance, and soap will lather quite easily. Using a water softener isn't necessary and might even remove beneficial minerals, so standard filtration is a better choice if you're concerned about taste or any occasional fine sediment. Sydney Water consistently meets the Australian Drinking Water Guidelines, reporting typical pH levels between 6.5 and 8.5, with no significant concerns regarding lead, copper, or PFAS.
