Following a significant blue-green algae bloom in Clear Water Lagoon, Lake Moondarra and Lake Julius in late 2013, the Mount Isa Water Board installed a filtration plant as an interim measure to filter all water supplied to Mount Isa City Council customers. This filtration effectively removes all blue-green algae from the water before oxidation and then supplied to Mount Isa City Council. New, permanent micro-filtration treatment plant was introduced in March 2015 which provides an appropriate level of assurance of the quality of water supplied to Mount Isa City Council.View All FAQs +
In February 2015, Mount Isa’s average daily consumption was approximately 600 litres per person per day.
Based on this figure, Mount Isa’s average daily consumption per person is more than 200% higher than Brisbane (<200 litres per person per day).
Compared with other similar-sized outback mining centres, Mount Isa’s average daily water consumption per person is 50% higher than Kalgoorlie-Boulder (400 litres per person per day) and 62% higher than Broken Hill (370 litres per person per day).View All FAQs +

Historically, the water in Mount Isa has been treated using a natural filtration and treatment process in Clear Water Lagoon. However, in late 2013, a significant blue-green algae bloom caused the lagoon’s natural filtration process to fail. This resulted in the lagoon being unable to provide water of an appropriate quality for the Mount Isa community without subsequent filtration. As there was no likelihood that the algae bloom could be resolved within a suitable timeframe, the Mount Isa Water Board urgently sourced a filtration system as an interim measure to ensure the continued supply of clean water to Mount Isa City Council.
In 2015 the blue-green algae bloom in Clear Water Lagoon grew to be potentially the largest ever recorded in a Queensland water supply system, with more than 6 million cells per millilitre (recorded 3 March 2015). 10,000 cells per millilitre is considered normal and acceptable. New, permanent micro-filtration treatment equipment was introduced in March 2015, expanding on the capacity of the emergency plant and providing an appropriate standard of assurance to the quality of drinking water supplied to Mount Isa City Council.View All FAQs +
