Contract Value

The WMPP remains the largest water infrastructure project undertaken in Australia. It involved the replacement of approximately 18,000km’s of inefficient earthen channel with 9,000km’s of pressurised pipeline and associated earthen and tank storages, pump stations and other structures. The pipeline supplies water to 8,000 rural properties andd 36 towns over an area of two million hectares (10% of the area of Victoria).

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.
