Can You Drink The Tap Water In Cairns?


Yes. Our water is safe to drink for everyone.

In fact, it’s actually pretty good! Cairns water is supplied from the Atherton Tablelands, where pollution is almost zero. We have modern-day filtering techniques which are on par with most of the major first world countries.

Where does Cairns water come from?

The Cairns community is supplied with water from Copperlode Falls Dam and Behana Creek. Water from Copperlode Dam supplies areas to the north of Cairns and the Cairns city.

The Behana Creek source supplies areas south of Cairns as well as the Cairns city. This water is treated at the Freshwater Creek Treatment Plant at Tunnel Hill.

There is, of course, these added chemicals;

  • Alum for flocculation and removal of particles at the water treatment plant
  • Sodium Hypochlorite for disinfection
  • Sodium Carbonate

Though this is standard through the whole of Australia. Our water is what’s considered ‘Soft’ with 10mgCaCo3/L.

Hard water… is water that contains an appreciable quantity of dissolved minerals (like calcium and magnesium).

Soft water… is treated water in which the only ion is sodium.
