How does the Mount Isa Water Board treat the water?

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.

Is the water tested?

More than 10,000 water-quality tests are conducted each year to ensure water supplied to MICC meets Australian Drinking Water Guidelines.
