Water Supply

Mount IsaLake Moondarra

Lake Moondarra is the primary water source for the city of Mount Isa.

The Mount Isa Water Board (MIWB) is responsible for the supply of quality bulk water to industrial customers and Mount Isa City Council (MICC).

MIWB is responsible for storing and treating bulk water for the region, overlooking the supply of water from Lake Moondarra and pumping from Lake Julius when required.

MICC then distributes the water to your property via an extensive network of pumps and pipes. Weekly testing is conducted to monitor the quality of your drinking water throughout the entire supply network.



MICC is responsible for providing water supply services to the Camooweal area.

Water is pumped from two sub-artesian bores which are then injected with chlorine for disinfection before continuing on to the town reticulation. Monthly testing is conducted to monitor the quality of the drinking water through the entire supply network.

It is our job to ensure that the water that pours from your taps meets the requirements of the Public Health Regulations and Australian Drinking Water Guidelines.
