Griffith Water Hardness & Quality Report (2026)

Griffith City Council (GCC) is responsible for supplying drinking water to the residents of Griffith, New South Wales, Australia. The raw water originates from the Murrumbidgee River, drawn via Murrumbidgee Irrigation’s main canal at Three Ways Bridge. This water then flows to the Griffith Water Treatment Plant (GWTP), which began operating in 1988. With a treatment capacity of 60 megalitres per day, the GWTP employs conventional methods such as coagulation, flocculation, sedimentation, filtration, and disinfection to prepare the water for consumption.

The Murrumbidgee River watershed begins in the Snowy Mountains and winds through the Murray-Darling Basin. Along its course, the water picks up minerals from alluvial plains, sedimentary rock formations, and agricultural runoff. The local geology is characterized by floodplain aquifers and riverbed sediments rich in calcium-bearing materials. These geological features, influenced by arid conditions and the weathering of rocks over time, are the primary reasons for the water's consistently hard nature.

Homeowners in Griffith will notice significant limescale buildup in appliances like kettles, dishwashers, and washing machines, which can reduce their efficiency and shorten their lifespan. Boilers and pipes are also susceptible to accelerated scaling, potentially increasing energy expenses. To combat this, monthly descaling with vinegar is advised, alongside installing faucet filters and using detergents specifically formulated for hard water. Given the water's hardness, installing a whole-house water softener is highly recommended to prevent spotting on dishes and fixtures, enhance soap lathering, and prolong the life of household appliances.
