Tea Tree Gully Sustainable Sewers

The Tea Tree Gully Sustainable Sewers program will transition all properties connected to the Community Wastewater Management System (CWMS) to a modern sewer system delivering nationally accepted levels of service for its customers.

Over the past two 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 for our staged approach to transition customers to our sewer network. This has informed how the program can minimise impacts and increase benefits for the community.

CWMS customers will be 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 has also taken full ownership of the existing Tea Tree Gully Community Wastewater Management System (CWMS), including management, operation and maintenance from 1 July 2022. Those 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.

Project delivery stages are available. The map below outlines the staged approach to transition customer connections.

Current status

Construction is now complete at our pilot sites on Glenere Drive, Dawson Drive, Angas Court and North East Road in Modbury, resulting in the connection of more than 60 households and businesses.

In parallel, construction is nearing completion for stage one of the program, which involves the connection of approximately 500 properties in Modbury North, St Agnes and Banksia Park. Stage two has also now begun, which includes further St Agnes properties as well as many in Tea Tree Gully and Vista. One of our crucial assets of a wastewater pumping station on Elizabeth Street is now operational, with a community working group established to help us build another in nearby Marsha Reserve.

In total, more than 10.000 metres of sewer main have been installed and 500 households are now connected to our sewer network.

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 the community.

Crews are currently working on streets including Whiting Road, Beatrice Avenue, Bowen Road and Perseverance Road.

Before we commence works to connect each property in stage, 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.
