Kallangur Water Hardness & Quality Report (2026)

Kallangur, located in Queensland's Moreton Bay Region, receives its water supply from Unitywater. This supply originates from North Pine Dam, situated on the North Pine River. The North Pine Water Treatment Plant processes the water, which is then distributed by Unitywater to numerous suburbs, including Kallangur. Seqwater manages the broader South East Queensland water grid, drawing from multiple sources like Wivenhoe and Somerset Dams to ensure a resilient supply. The watershed itself is part of the North Pine River catchment, contributing to the overall water resources of South East Queensland.

The geology influencing Kallangur's water is characterized by Mesozoic-era sedimentary rocks from the Clarence-Moreton Basin. These include sandstones and siltstones, with some Tertiary basalt flows and overlying alluvial sands. Unlike regions with significant limestone deposits, this area lacks substantial karst systems or limestone aquifers. The surface water runoff, which feeds North Pine Dam, interacts minimally with calcareous materials. Consequently, the water is naturally soft, containing low levels of dissolved minerals like calcium and magnesium.

Because the water is soft, residents in Kallangur will likely notice less limescale buildup in appliances such as kettles and hot water systems, and in household pipes. This can extend the lifespan of fixtures and reduce the need for frequent descaling. You might also find that less soap, detergent, and other cleaning agents are needed to achieve effective results. However, very soft water can sometimes be mildly corrosive to metal plumbing over extended periods; keep an eye out for any unusual blue-green staining on fixtures, which could indicate copper leaching, and consider having your pipes inspected if this occurs.
