Background information

After the record rainfall we experienced in July and the significant storm event and flooding, a drain pipe (culvert) under Karnup Road, Serpentine (near Wellard Street), failed and caused a sink hole on 21 July, 2021.

Following inspection of the drain, it has been identified that a 24-metre length of 2m x 1.5m diameter ribbed steel pipes have rusted out and require replacement.
