Craigmore Water Hardness & Quality Report (2026)

SA Water provides drinking water to Craigmore, a northern suburb of Adelaide, South Australia. The supply is a blend of surface water drawn from the River Murray and groundwater sourced from local aquifers within the Adelaide Plains. River Murray water undergoes primary treatment at facilities like the Morgan Treatment Plant, while groundwater is also processed. This water is then distributed across the metropolitan network, which serves more than 1.4 million residents throughout Greater Adelaide.

The River Murray Basin forms the primary watershed, stretching across southeastern Australia. Its catchments are characterized by limestone karst and alluvial sediments dating back to the Mesozoic and Cenozoic eras. The local groundwater originates from Adelaide Plains Basin aquifers, which include unconfined sands and confined layers within Tertiary limestones. These geological conditions, rich in calcium- and magnesium-bearing rocks such as the Murray Basin limestones, contribute to a moderately mineralized water supply. The long journey of the river allows for mineral pickup, and natural leaching from aquifers further increases dissolved solids.

Homeowners may notice a mild buildup of limescale on fixtures like kettle elements, taps, and showerheads from this moderately hard water. Appliances such as hot water systems and dishwashers can become less efficient due to scale accumulation. To manage this, regular descaling with vinegar or the use of scale filters can be helpful. You might also find that you need less detergent as the water lathers reasonably well. For those experiencing soap inefficiency or persistent fixture staining, installing a water softener is often recommended to prolong the life of appliances. The water's pH of 0.05 is outside the guideline range, but total dissolved solids are moderate at 340 mg/L, and turbidity is low at 0.1 NTU.
