Water quality issues were raised for Kirup & Balingup during 2013. Here is the reply from the Water Corporation:
“For the last 5 years Kirup’s water has been a blend of Kirup Dam supplemented with the Mullalyup soak. From March to August 2013 the Water Corporation has carted water from the ground water source in Donnybrook and entered it directly into the Kirup system which would have most likely given a different taste to the water but the quality of the water is fine. As the dam is full again (Oct 2013) just the dam water is being used as the source, and users may have noticed a change in taste again.”
Note that the Water Corporation is aiming to improve the supply and quality of water for Bridgetown, Boyup Brook, Hester, Greenbushes, Balingup, Mullalyup and Kirup via the Bridgetown Regional Water Supply Scheme.
