Mount Isa Water

Mount Isa Water Board is a Category One Water Authority established under the Water Act 2000. The Mount Isa Water Board operates as a commercialised statutory authority carrying out water activities in the Mount Isa region in the State of Queensland.

Water quality

The Mount Isa Water Board has a comprehensive water quality monitoring program, which includes, amongst others, monitoring of the following common parameters:

pHTemperatureDissolved Oxygen
Electrical ConductivityColourTurbidity
MetalsHeavy MetalsEscherichia Coli
Blue-Green AlgaeChlorine 

Water is tested at various locations within Lake Moondarra and Lake Julius to determine the raw and recreational water quality, and at various locations within the Mount Isa Water Boards water treatment, transmission and distribution networks for treated water quality.

The results are compared to the ‘Australian Drinking Water Guidelines’ (ADWG) for treated water and ‘Australian and New Zealand Environment and Conservation Council Guidelines’ (ANZECC) for raw water.

Water is monitored on a continuous, daily and weekly basis depending upon the parameter, its importance within the water treatment system and the time of year. Eg chlorine is monitored continuously at the main water treatment plant distribution points, while blue-green algae is tested weekly, during summer.
