The Nimmie Caira Stock and Domestic Water Supply Scheme supplies stock and non-potable domestic water to the entire Nimmie Caira property. The property is 84,417 ha situated in the lower reaches of the Murrumbidgee River floodplain (the Lowbidgee) between Maude and Balranald, South Western NSW. It is a vital component the Lowbidgee being the largest remaining area of wetlands in the Murrumbidgee Valley. The project balances environmental and Aboriginal cultural heritage protection with commercial use, and by doing so creates an asset for the local community and the Murray Darling Basin.

Major construction challenges included major river crossings, a variety of cultural heritage sites and liaising with some 4,000 property owners.

Mitchell designed and constructed six of the seven supply systems in just over 3 years, delivering the project 6 years ahead of the original 10 year time frame.

Mitchell’s safety performance on the project was outstanding, completing 900,000 manhours without a single LTI.
