Source of Water in Cairns, Australia

Cairns tap water mainly comes from Copperlode Falls Dam, also known as Lake Morris, in the rainforest southwest of the city. The dam stores water from the Mulgrave River catchment.

Additional water is sourced from Behana Creek and Freshwater Creek. These supplies are treated at local water treatment plants before entering Cairns Regional Council’s distribution network.

Cairns Drinking Fountains

Public drinking fountains in Cairns are generally safe to use when they are connected to the treated town water supply and clearly marked as drinking water. Queensland public water supplies are required to meet Australian drinking water quality standards.

Avoid fountains that are labelled non potable, look dirty or damaged, or have stagnant water around the outlet. Let the water run briefly before drinking, especially after the fountain has not been used for some time.
