What Makes Banora Point's Water Unique?
Local geology and source profile
Banora Point's drinking water is supplied by Tweed Shire Council Water, drawing from Clarrie Hall Dam (formerly Bungalora Dam) on the Doon Doon Creek in the upper Tweed River catchment for the Tweed LGA in far northern New South Wales. Water hardness in Banora Point is measured at 184.5 mg/L — classified as hard, approaching the Australian Drinking Water Guidelines (ADWG) aesthetic guideline of 200 mg/L published by NHMRC. Banora Point — a popular residential community on the Tweed River at the NSW-QLD border corridor adjacent to Tweed Heads, known for its Tweed River foreshore lifestyle, the Banora Central shopping precinct, and the Panorama Drive elevated residential estates overlooking the Tweed Valley — carries one of the harder supplies for a coastal northern NSW community.
Banora Point's elevated hardness reflects the Tertiary basalt, rhyolite, and trachyte geology of the Tweed Shield Volcano catchment. The Doon Doon Creek and Tweed River headwaters drain across the ancient Tweed Shield Volcano complex — centred on Mount Warning (Wollumbin) — where Miocene-age volcanic basalt, rhyolite, and associated tuffite provide elevated calcium and mineral dissolution. The volcanic terrain of the Northern Rivers contributes notably higher calcium and mineral loading than the granite-dominant catchments of the southern NSW ranges, producing the 184.5 mg/L hard supply at Banora Point consistent with the basalt volcanic geology.
Banora Point residents face significant limescale build-up on taps, shower screens, and in kettles — descaling every three to four weeks is typical. Hot water systems benefit from annual inspection. The elevated lead reading (0.005 mg/L) warrants always briefly running the cold tap before drinking in older Banora Point properties. Tweed Shire Council provides water quality information online, with all ADWG health standards consistently met. A water filter is a practical investment for Banora Point residents in this Northern Rivers border community.
