SA Water completes $11.4 million wastewater network upgrade

SA Water has completed an $11.4 million capacity upgrade of the wastewater network that services the majority of the Adelaide CBD and the city’s south-eastern suburbs.

Works on the Western Adelaide Wastewater Network involved the installation of a new 2.5 kilometre pipeline from West Terrace, through the Adelaide Park Lands, connecting into an existing sewer main at the North Adelaide Golf Course on War Memorial Drive.

The project is a finalist in this year’s Australian Water Association’s (AWA) South Australian Water Awards in the ‘Infrastructure Project Innovation’ category, due to the complexity of the engineering and its emphasis on delivering in a socially sustainable way.

Careful planning was undertaken to limit and continually monitor the impacts of construction on the Adelaide Park Lands environment, community, sites of Aboriginal significance and historical relics.

The upgrade supports expected local growth in urban development and residential population by transporting increased sewage flows and helping reduce the potential for operational or odour issues that could occur if the existing infrastructure couldn’t meet demand.

One of the existing sewer mains, which the new pipe was connected into under West Terrace, is a original oval-shaped sewer main from the 1860s.

The AWA South Australian Water Awards will be presented on Friday, 17 November 2017.

“This part of the sewer system supports an area that is fast becoming a development hub, and this upgrade was imperative in order to maintain a reliable and resilient network,” said Water and the River Murray Minister Ian Hunter.

“During all stages of this project, SA Water and its contractors made a concerted effort to give consideration to minimising impacts on the surrounding area and people.”
