The project was designed to improve the water supply security of the existing Tantawangalo-Kiah water supply system. It will also lessen extraction of water from Tantawangalo Creek and the Kiah Borefield during low stream flows by connecting a new source of water to the system and enhance operational flexibility in the supply of water from the sources and dams to customers.
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.
