Tea Tree Gully Sustainable Sewers

The Tea Tree Gully Sustainable Sewers program is working to transition all properties connected to the Community Wastewater Management System (CWMS) to a modern sewer system delivering a national standard quality of service for its current customers,

Over the past four years, our dedicated project team has worked closely with the City of Tea Tree Gully and local community to gain and share feedback that has guided the planning and prioritisation process. CWMS customers are being connected in stages, with prioritisation based on a range of criteria. This includes proximity of properties to our existing sewer network, community feedback, alignment with upcoming council and development works, and areas with a reported history of blockages and overflows from the existing CWMS infrastructure.

SA Water took ownership of the existing Tea Tree Gully Community Wastewater Management System (CWMS), including management, operation and maintenance from 1 July 2022. Those still on the CWMS can contact 1800 657 337 for all current sewerage and CWMS related service enquiries. All residents connected to CWMS are now SA Water customers for their sewerage services. Accordingly, those connected to the system pay SA Water sewerage rates instead of the previous Council CWMS service charge

Revised project delivery stages are now available from July 2024.

The map below outlines the new staged approach to transition customer connections.

All remaining properties have been re-evaluated and organised into smaller delivery areas within four separate construction zones. Properties will be converted sequentially across these zones to ensure we respond to both construction requirements as well as stakeholder feedback received from Stage 1 of the project, which focused on managing impacts to the wider community and minimising traffic congestion in and around local streets, schools, and businesses.

Crews are currently working across areas in multiple areas Banksia Park and Tea Tree Gully, and with more than 700 properties now converted, we are working towards a revitalised and strategic approach based on direct community feedback.

One of our crucial assets, a wastewater pumping station on Elizabeth Street, is now operational, with a community working group completed to help us build another in nearby Marsha Reserve later this year. As we progress through these stages, multiple crews will continue working across multiple sites each day, ensuring we complete work safely and efficiently and in a way that minimises construction impacts to those nearby.

We have a dedicated team working with residents and stakeholders to help ensure this project delivers successful outcomes for not only CWMS customers but the wider Tea Tree Gully community. Before we commence works to connect each property, we will meet with property owners at a convenient time to discuss the pipeline routes and the local scope of works. We will continue to keep all CWMS customers informed throughout this project and assist you when the time comes to transition your sewer service from the CWMS to our network. All properties will be reinstated upon completion, with septic tanks decommissioned and filled in.
