Due to recent high rainfall on Tuesday 9 September and infiltration of stormwater into the sewerage system, diluted sewage may have discharged to Dandenong, Merri, Moonee Ponds, Mullum Mullum, Scotchmans and Westbreen Creeks in the northern suburbs of Melbourne via Emergency Relief Structures. The system is designed for this to happen to ensure that the sewage does not back up through the sewers and into people’s properties. Avoid contact until further notice.
