South East Water has completed sewer works across Bentleigh and Noble Park to boost capacity for Glen Eira and Greater Dandenong’s growing populations. 

The upgrades include a new relief sewer designed to increase network capacity and reduce the likelihood of surcharges and spills during wet weather events. The works aim to strengthen the area’s sewer network for the next 50 years. 

The project delivered new relief sewer pipelines and upgrades across Noble Park, Noble Park North, McKinnon, Bentleigh and Bentleigh East. These improvements provide additional sewer storage and a more reliable service for customers. 

South East Water General Manager Liveable Water Solutions Charlie Littlefair said the upgraded network supports growth across Glen Eira and Greater Dandenong while delivering safe and reliable services, day and night.  

“These upgrades reduced the risk of spills in wet weather and adds extra network capacity, helping protect local homes, parks and the environment for decades to come,” he said. 

“We know these works were significant, and we thank the community for their patience as we completed excavations and reinstated the areas.” 

As part of the works, South East Water also installed a new drinking fountain and dog bowl at McKinnon Reserve, featuring new Aboriginal artwork. 

The projects were delivered by the Zinfra, Jaydo and WSP joint venture partnership as part of South East Water’s proactive major works program. 

South East Water is also renewing the Bentleigh Interceptor Branch Sewer, upgrading 5km of pipeline across Brighton East and Bentleigh. The upgraded asset will improve reliability across the wider network.
