** SA Water is now completing post-commissioning works for this project. You may notice a maintenance issue and leaking water on Calton Road at the front of the tank. This is not related to the tank construction works. SA Water is prioritising this complex repair and will resolve it as soon as possible***



SA Water is upgrading the Gawler Tank, a vital part of the local water supply network that has served the Gawler-Virginia community for over a century. Originally constructed in 1907, the 1.268 ML concrete tank has reached the end of its operational life. To ensure ongoing reliable water services, we are replacing the existing structure with a modern 3ML tank at the same location on Calton Road, Gawler East.

The new tank will enhance the capacity and resilience of the water supply, benefiting 6,200 customers in the region. This project involves safely demolishing the existing tank, upgrading associated infrastructure, and constructing a durable new tank to meet current and future needs. Once completed, the upgraded tank will continue to play a crucial role in delivering safe, reliable drinking water to the community.

What to expect:

Traffic Management
A detour will be in place for the duration of the works. Barossa Avenue will be closed to through traffic, with access permitted for Barossa Avenue residents only.

    Hello, this leaking water relates to a maintenance issue in the water main that runs down Calton Rd, it is not related to the tank construction.  The repair is complex and our teams are planning the repair to minimise the impact as much as possible.  We expect this to be completed by next week.

    Hi Leanne, thanks for your question.  This leak is not related to the tank however I do know that it is positioned quite close by.  There is a leak in the major water main that runs under this road and the repair requires quite a bit of planning.  SA Water is aware and will be completing this as soon as possible

    Hi Denise

    I apologise for the impact to you.  This is our last bit of noisy works as we are backfilling soil around the tank perimeter and there is some compaction equipment.  The tank is filled with water and supplying water to the area now. Once this backfilling is complete Barossa Ave will re-open and there are only bits and pieces for us to complete, hopefully you wont notice us much after this.

    Kind Regards

    Laura

    Hi Lizzy, thanks for your question.  Our work on building the tank will be fully completed by Spring 2026.  The main earthworks component of our works is now over so the dust you are experiencing should start to trend downwards.  Please contact me at project@sawater.com.au if you would like any more specific information.
