Established in 1973, Mount Isa Water Board (MIWB) operates as a commercialised statutory authority under the Water Act 2000 (Qld). At MIWB, our primary responsibility is to provide essential water services to the Mount Isa community and its industries. We are committed to ensuring a reliable and high-quality water supply through the distribution and treatment of bulk water from Lake Moondarra and Lake Julius.

MIWB constructs, operates, and maintains the bulk water transport and treatment infrastructure that transports bulk water from storages at Lake Moondarra and Lake Julius

in accordance with term contracts with three major customers:

• Mount Isa City Council which reticulates potable water to approximately 20,000 people

• Mount Isa Mines Ltd a Glencore company, which uses non-potable water in extraction, concentration and smelting processes.

• Incitec Pivot Ltd which uses non-potable water for manufacturing acid.

In addition to providing bulk water transport and treatment services, we also provide high voltage electricity infrastructure services to the North West Queensland Water Pipeline Pty Ltd (NWQWP), a subsidiary of SunWater Limited. This role highlights the strategic role MIWB plays in driving growth in North West Queensland.

MIWB is also proudly the Trustee of Mount Isa’s largest water catchment and recreation reserve, the R48 Reserve. The R48 Reserve is situated around Lake Moondarra, which provides a sanctuary for wildlife and popular leisure areas. We maintain recreational facilities including picnic and play areas and water sports facilities which are enjoyed by thousands of people each year, including residents and visitors to the region.
