Works are continuing on the pilot project to transfer CWMS customers over to SA Water’s sewerage network, with the first properties connected. The Minister for Environment and Water, Hon David Speirs MP and I, recently visited Glenere Drive in Modbury to talk to thrilled residents and hear about their experience. The construction of 134 metres of gravity sewer main took place in December 2020 with on-property works now underway. The pilot project has provided valuable knowledge and insight on the complexities of transferring CWMS customers to SA Water’s sewerage network.  

The overall work to transfer CWMS customers will be completed in stages as outlined in SA Water’s Transition Plan. Head to for more information on the staged process and to view the Transition Plan.    

SA Water will be working closely with households to provide specific details about commencement dates and the scope of works. There are several possible infrastructure and on-property technical options available to convert CWMS customers to SA Water sewerage network. Each option is dependent on a number of key criteria to ensure that the acceptable levels of service are achieved and maintained for each property within the catchment. SA Water will conduct an individual assessment of the infrastructure and on-property options at each house to determine the most appropriate solution applicable to the specific catchment conditions.  

We are fixing this decades old issue at no cost to the household and giving residents in the north east a modern, reliable sewer system that delivers nationally accepted levels of service for its customers. Once transitioned households will save up to $400 a year and receive a sewerage service with a 24/7 customer care response service. I will continue to keep you updated as this project progresses.
