North Lakes Water Hardness & Quality Report (2026)

Urban Utilities supplies North Lakes, a community within the Moreton Bay Region of Queensland. The water comes from the South East Queensland Water Grid, managed by Seqwater. Key sources include Wivenhoe Dam, Somerset Dam, and North Pine Dam, all drawing from the Brisbane River and Stanley River catchments. After treatment at facilities such as Mt Crosby West Bank and North Pine Water Treatment Plant, the water is distributed by Urban Utilities.

The catchment area covers the Brisbane River watershed, originating in the Great Dividing Range. This region is characterized by Mesozoic sedimentary rocks, including sandstones, siltstones, and mudstones belonging to the Clarence-Moreton Basin. Volcanic basalt flows also feature, but unlike areas further south, significant limestone formations are absent. High rainfall and the rapid flow of surface water over these rocks mean less time for minerals to dissolve, resulting in a soft water supply with low levels of calcium and magnesium.

Homeowners in North Lakes will likely notice that this soft water doesn't leave much scale on appliances like kettles or in pipes. You'll find that soap lathers up easily, and you probably won't need to worry about frequent descaling of your water heater or dishwasher. Installing a water softener isn't generally recommended here; it could add unnecessary sodium to a supply that already has very few dissolved minerals. The water quality adheres to the Australian Drinking Water Guidelines, with Urban Utilities reporting compliance for various parameters like lead and copper.
