From April 2025, construction will begin to install approximately 7.5 kilometres of new wastewater mains in Reid, Willaston, Gawler Belt, and Roseworthy, along with a new pump station on Davidson Road in Reid. This new infrastructure will provide reliable services for existing customers and support future growth in the Roseworthy area.

Where works will occur (see map below for details):

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

What to expect

We’re committed to minimising disruptions and keeping you informed throughout the works.

If you’re affected by the works, we’ll let you know in advance and work closely with property owners, residents, businesses, and road users before and during the project. To complete this work as quickly as possible while keeping disruptions low, some activity may happen during the day, night, or weekends. We’re also looking at all options to reduce road closures, detours, and traffic delays.


Please note, timeline dates are subject to change based on program requirements and weather conditions
