What Makes Melton South's Water Unique?

Local geology and source profile

Source: ReservoirTDS: 15.3 mg/LpH: 7

Greater Western Water supplies the Melton South area in Victoria, Australia, through its extensive network. The utility draws drinking water from a variety of sources, including reservoirs and groundwater systems situated across Western Victoria. These raw supplies are then processed at treatment plants to meet the stringent Australian Drinking Water Guidelines before being delivered to homes and businesses.

The Melton South water supply originates from a region known for its Western Plains geology. This area is characterized by Quaternary alluvial deposits resting atop Tertiary volcanic formations. While these layers do contribute some dissolved minerals to the water, the specific geological makeup results in a notably soft water profile for the community.

Homeowners in Melton South will likely notice that their appliances and plumbing are well-protected from the damaging effects of limescale. Because the water is soft, you won't have to worry about significant buildup on fixtures, heating elements, or inside your water heater. Soap and detergents will lather readily, and you may find that you don't need as much product. Water softening systems aren't generally recommended for this supply.
