How does the Mount Isa Water Board treat blue-green algae?

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 and is expected to be fully operational by the end of September 2015.

Where does our raw water come from?

Mount Isa’s raw water is supplied from either Lake Moondarra or Lake Julius. Lake Moondarra is 13 km downstream from Mount Isa and Lake Julius is more than 60km away. In normal conditions, all water is supplied from Lake Moondarra. However, when there is a drought, water is also supplied from Lake Julius.

Why was a water levy imposed?

The levy is a matter for Mount Isa City Council. As per the Mount Isa Water Board’s contract with Council, the essential major expense associated with implementing the emergency leased filtration system was passed on at cost price.

As part of negotiations for new equipment, the Mount Isa Water Board has negotiated with the supplier to secure a substantial reduction in charges effective 1 February 2015 for the current filtration system. The cost has now been reduced from $250,000 per month to $10,000 per month, representing a saving to Council of at least $1.19 million this financial year which has been rebated to rate payers.
