Tea Tree Gully Sustainable Sewers

Share on Facebook Share on Twitter Share on Linkedin Email this link

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, Barker Avenue, Sandra Avenue, White Avenue, Tregeagle Avenue and Bowen 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.

    Will SA Water be removing the old common effluent tank with the roll out of mains sewer?

    Not sure asked about 2 months ago

    Hello, 

    Thank you for reaching out. 

    As part of the works, SA Water will not be removing the septic tank. Instead, we will decommission your septic tank by pumping it out, disinfecting and backfilling with clean fill, as per the SA Health On-Site Wastewater Systems Code. The old tank will remain and become part of the ground. 

    Additionally, your tail pipe that connects from your septic tank to the Council Community Wastewater Management System (CWMS) main will also be capped as part of this decommissioning process. Capping will disconnect your property from the CWMS main and will prevent wastewater from the CWMS main entering your property. 

    I hope this helps answer your question. Please don't hesitate to contact us if you have any other questions. 

    Regards

    Winnie Nguyen

    I just wanted to check when my street and property will be done as they are right by my Street now. It's 1 Bowen Road Tea Tree Gully

    Olivia asked about 2 months ago

    Hi Olivia 

    Thanks for reaching out. 

    Our crew is currently laying the new sewer main in Bowen Rd between Lewis Avenue and Perserverance Avenue. 

    The part of Bowen Rd where your property is situated will necessitate underground drilling to connect the new sewer main on Bowen Rd to Whiting Road. We have scheduled these works to take place within the next few weeks. Rest assured, we will send you a formal notification via mail prior to the commencement of these works to keep you informed and prepared.

    Once the sewerage mains along your street are completed, we will proceed with on-property works. This phase will include the installation of sewerage infrastructure, including pipe work and, in some cases, pressure sewer equipment within your property's boundary, connecting to\ our sewerage mains network. These on-property works are expected to commence around March 2024.

    Our team will reach out to you soon to coordinate a meeting at your property. During this meeting, we will discuss the detailed scope of the required works and address any questions or concerns you may have. We understand the significance of these improvements and are committed to ensuring the process is as smooth with minimal impact as possible.

    If you have any questions or require further information at any time, please do not hesitate to contact us.

    Regards

    Who will pay for the electricity to run the pump and who will pay to replace the pump if it breaks?

    Jeff Lang asked over 1 year ago

    Hi Jeff,

    Thanks for touching base.

    In line with the State Government commitment that customers will not bear the cost of connecting to SA Water, we will install, own, and maintain pressure sewer infrastructure and cover the associated costs. 

    This includes covering the cost of electricity consumed by pumps operating pressure sewer systems. The pumps are very efficient and only use around $20.00 of electricity each year. We will cover this cost and you will see $5.00 removed from your water bill each quarter.

    If you would like to discuss, please give me a call on 7424 2489.

    Thanks

    Hi Paul, do you cover the cost of removing the existing septic tank?

    Gary1 asked about 2 years ago

    Hi Gary,

    Thanks for touching base.
    As part of the program, we will not be removing septic tanks. We will decommission your septic tank by pumping it out, disinfecting it and backfilling with clean fill. This will be at no cost to the customer.

    If you have any further questions, please give me a call on 7424 2489.

    Is this still free to all houses.

    Ashward asked about 2 years ago

    Hi Ashward,

    Thanks for touching base. 

    Yes, the State Government has committed $65 million during our current regulatory period (2020-24) to transfer customers from the CWMS to our sewer network, ensuring that customers are not required to pay for the cost associated with fixing this issue.

    Detailed costings for later stages beyond 2024 are being developed and will be informed by learnings in earlier stages of this complex project.

    If you have any further questions or would like to discuss further, please call me on 7424 2489.

    We are in the stage 3 group. We are concerned that at this time there is no plan to financially transition us off the TTG CWMS. Under ESCOSA regulations the shrinking pool of residents will need to pay for the system until transitioned. Based on current costings this will be impossible for the individual rate payer to absorb. What plans are being discussed to mitigate this situation please. Than you

    Vicki asked over 2 years ago

    Hi Vicki,
    Thanks for your question.
    The State Government has directed SA Water to work towards transitioning all CWMS customers, including those in stage three. We understand the City of Tea Tree Gully Council have a range of options to manage the cost of operating the CWMS and minimise the impacts to customers in the interim.

    If you have any further questions, please give me a call on 7424 2489.

    I thought there was no cost to residents. Last week I saw something saying there was discussion at the council working out the cost to residents to help pay for the transition. Also, after works have been done on our properties, will there be compensation or work done to replace items for the destruction of our property? Paths, walls, driveways etc.

    The on property pressure sewer units - who will own these when installed (SA Water or the property owner) and cover the replacement costs into the future when they are worn out and need replacement. I believe that these will also have an ongoing power cost will the property owner be reimbursed for this cost - as it states that clients will be transferred onto SA Water at no cost to the resident.

    sherrywatts asked over 2 years ago

    Hi Sherry,

    Thanks for your questions around the on-property pressure sewer option. In line with the government commitment that customers will not bear the cost of connecting to SA Water, we intend to install, own and maintain both pressure sewer and gravity sewer infrastructure and cover the costs associated with these options. This includes covering the cost of electricity consumed by pumps operating the pressure systems.

    If you would like to discuss further, please contact me on 7424 2489.
