Casino Water Hardness & Quality Report (2026)

Richmond Valley Council draws drinking water from the Richmond River above Jabour Weir west of Casino, New South Wales. This water is processed at the Casino Water Treatment Plant before being distributed to around 10,000 residents in Casino and neighboring communities. The regional utility's supply is supplemented by Rous Water, the bulk water provider for the area. Water quality checks are conducted regularly, adhering to NSW Health guidelines, ensuring safe drinking water for the Northern Rivers region.

The water's journey begins in the Clarence-Moreton bioregion, shaped by ancient Mesozoic sedimentary rocks like sandstones, siltstones, and mudstones from the Kangaroo Creek Formation and related sequences. These rocks, along with underlying basement materials, mean the Richmond River picks up only moderate mineral content. Because the geology lacks significant limestone or dolomite, the water remains characteristically soft, with minimal calcium and magnesium.

Homeowners will notice that this soft water leaves little scale buildup in appliances like kettles, dishwashers, or washing machines, potentially extending their lifespan. You'll find that soaps and detergents lather easily, meaning you might use less. However, you could see minor spotting on glassware or fixtures due to the low mineral content. There's no need for descaling efforts, and installing a water softener isn't advised; it could over-soften the water and potentially lead to pipe corrosion issues.
