Upgrading our wastewater network in Reid, Willaston, Gawler Belt and Roseworthy

To support current and future customers in the region, we’re delivering a major upgrade to the local wastewater network.

Construction is now underway to install approximately 7.5 kilometres of new wastewater mains across Reid, Willaston, Gawler Belt, and Roseworthy, along with a new pump station on Davidson Road in Reid.

This new infrastructure will help provide reliable wastewater services to existing customers and support continued growth in the Roseworthy area.

Where we’re working
(See map below for details)

  • Paternoster Road
  • Kentish Road
  • Redbanks Road
  • Twartz Road

What to expect

  • Changed traffic arrangements will be in place across the area until mid-2026
  • Work may take place during the day, at night or on weekends to help maintain schedule and minimise disruption
  • You may notice some noise, vibration and dust during construction
  • We’ll continue working closely with the community to minimise impacts wherever possible

Please note: Timeline dates are subject to change based on program requirements and weather conditions.

What happens to roads and footpaths after our works?

We work closely with the local council and follow all required reinstatement obligations, reinstating the parts of the road, footpath or the environment directly impacted by our works.
