Water sources

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 raw water is treated at Council's treatment plants and then stored in our 76 reservoirs.

Council's YouTube site Water infrastructure provides a technical account (with subtitles) of water and wastewater infrastructure for professionals and specialist authorities.

Copperlode Falls Dam

Copperlode Falls Dam has a total capacity is 38,400 megalitres (ML).

The Copperlode Dam water summary report (PDF) provides catchment information (volume available, spillway level* and rain gauge) as well as daily intake water production for Freshwater Treatment Plant and Behana Treatment Plan.

Report notes: when spillway level is 0mm, dam is 100% full.  All readings are are based on the previous day.

Southern rural water supply

Residents south of Aloomba to Bartle Frere and in the Mulgrave Valley receive water via small intakes (creeks). Treatment includes disinfection prior to being sorted in a supply reservoir for delivery to customers.  Monthly drinking water quality results are available below:

Drinking Water Quality

Cairns Regional Council undertakes an Annual Review of the Drinking Water Quality Management Plan in line with the Water Supply (Safety and Reliability) Act 2008. The management of drinking water quality outlined in the Act aims to protect public health.

Included in the Drinking Water Quality Management Plan is a Register of high risk stakeholders which includes elderly and the immunocompromised. Cairns Regional Council’s Water and Waste Department are inviting those who believe they may fit into this category to apply for inclusion on the Register.

Sometimes the chlorination and filtration system may not be able to adequately filter and disinfect the water due to storm events decreasing the quality of raw water or due to unforeseen mechanical faults. This increases the risk of microbiological contamination. Cairns Regional Council’s Water & Waste department regularly takes water samples to test for waterborne pathogens and bacteria, e.g. E.coli and Cryptosporidium which can cause illness. If the supply cannot be guaranteed as fit for use, further testing is undertaken and a Boil Water notice is issued in consultation with QLD health.

Those who believe they may fit into this category are invited to apply for inclusion on the High Risk Stakeholder Register by completing the Contact Information Registration form ( PDF, 0.23 MB ).

If you have any further comments or concerns, please add them to the form or contact Water & Waste’s Quality & Compliance Unit on 1300 69 22 47 to discuss further.
