Fairbairn Dam Spillway Safety Improvement

SunWater has identified improvements to the Fairbairn Dam spillway lower chute floor are required in order to return the spillway to its designed functionality.

Project Duration

First stage commenced in April 2016 and was completed in December 2016. The second stage commenced in April 2017 and is scheduled for completion late 2018.
