Unitywater Executive Manager Customer Delivery Rhett Duncan said the utility had been closely monitoring water quality since the incident occurred.

“We have worked very closely with Sunshine Coast Council and have been taking daily samples at a number of locations around the creek and lake,” he said.

“The results show that any impact from the broken sewerage pipe has now cleared and we have taken down the signs.

“We encourage the community to consider their own health and safety when swimming in any waterway following heavy rain as stormwater can contain contaminants such as animal faeces, oil and petrol, fertilisers and pesticides washed from roads, footpaths and gutters.

“We thank the local community for their understanding and patience as we’ve worked to resolve this incident.”
