Casino is supplied by Richmond Valley Council, which reports it together with the Mid Richmond scheme in its quarterly chemical results. The figure shown, 100.0 mg/L CaCO₃, is the median across 3 supply zones, which range from 97.0 to 110.0 mg/L, so it depends on which zone your street is in. Light scale on kettles and taps is likely, and descaling normally keeps it in check.
Australian Drinking Water Guidelines: aesthetic target ≤ 200 mg/L CaCO₃.

What it means at home
- Visible kettle scale every few weeks; vinegar or citric acid is enough.
- Water heater and washing machine: some long-term scale; a scale inhibitor slows it.
- Dishwasher: medium salt setting.
- Softener optional; pays off mainly with a gas boiler or tankless heater.
How much salt will you use for softening?
Optional. A scale inhibitor or a small softener protects the heater; soap savings are modest.
Descale a coffee machine or kettle about every 3 months (typical manufacturer guidance for this hardness).
Estimates for planning, not a quote. Check your appliance manual for exact settings.
