Tweed Shire Council (Bray Park Weir / Clarrie Hall Dam) supplies the built-up coastal strip; Rous County Council (Rocky Creek Dam) reaches into the Byron hinterland townships.
Coastal aerosol corrosion accelerates iron and manganese staining; hinterland canopies drive higher microbiological load year-round.
Wollumbin caldera bore water is often hard, mineral-rich and iron-heavy — the same basalt aquifer signature as central Murwillumbah.
Stock and irrigation on hinterland acreage — human-contact use warrants annual microbiology screening.

Tweed Heads, Banora Point, Kingscliff, Cabarita. Coastal aerosol corrosion and mixed mains-plus-tank supply — Tweed Shire Council water on the mainland strip.

Murwillumbah, Uki, Chillingham. Wollumbin caldera bore chemistry — hard, iron- and manganese-rich; tank properties on acreage.

Byron Bay, Suffolk Park, Mullumbimby, Ocean Shores. Flying-fox bat overflights and dense subtropical canopy drive tank microbiological risk.
