Gawler Belt: Paternoster, Kentish, Redbanks and Twartz Roads
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.
