 FAQS

Why do we have a filtration system? What happened to Clear Water Lagoon?

In late 2013, a significant blue-green algae bloom caused Clear Water Lagoon’s natural filtration process to fail. This resulted in the water in the lagoon being unsuitable for Mount Isa Water Board to supply to Mount Isa City Council for use by 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.

The blue-green algae bloom in Clear Water Lagoon grow to be potentially the largest ever recorded in a Queensland water supply system. Levels of blue-green algae have risen to never before seen levels of more than 6 million cells per millilitre in March 2015 — 10,000 cells per millilitre is considered normal and acceptable.

While investigations are currently being undertaken into the future of Clear Water Lagoon, the Mount Isa Water Board now considers a filtration system essential to future operations. Recent events have demonstrated that Clear Water Lagoon can no longer be relied on to the extent it has been in the past and will not be able to meet the process assurance requirements of modern drinking water standards. A permanent water filtration facility has now been established to assure Mount Isa’s drinking water quality.

What’s being done to increase the city’s supply of clean water?

The Mount Isa Water Board has implemented a long-term solution to expand filtration capacity to a reliable average of more than 22 megalitres per day from March 2015. This will increase the amount of water that can be provided to Mount Isa City Council for local use and reduce the need for restrictions, subject to rainfall.

What are the roles of the Mount Isa Water Board and Mount Isa City Council in the supply of water to the city?

The Mount Isa Water Board is responsible for supplying bulk treated water to Mount Isa City Council. The Board conducts extensive water quality tests to ensure the water meets Australian Drinking Water Guidelines.

Once the Mount Isa Water Board has provided the water to Mount Isa City Council, the Council is responsible for the supply of water to Mount Isa residents through its extensive pipe network. Mount Isa City Council is also responsible for conducting further chlorination and testing of the water prior to its distribution to residents.

Does the Mount Isa Water Board make a profit?

The Mount Isa Water Board has made a profit in most years and has consequently paid taxes and dividends to the State Government.

From the time the Mount Isa Water Board was commercialised in 2000 until 2011–12, all dividends and taxes were passed on by the State Government to Mount Isa City Council, amounting to $28 million poured back into the Mount Isa community over that period.

Current State Government policy is that Mount Isa City Council will receive 50% of the total dividends and taxes generated by the Mount Isa Water Board in a financial year (July to June). However, this is conditional upon the Mount Isa Water Board making a profit for the year.

Provided MIWB makes a profit, the receipt of dividends and tax by Mount Isa City Council offset a significantly proportion of the cost of water charges.
