Contract awarded for sewer upgrade in Adelaide


SA Water has awarded the contract to upgrade the sewer network in Adelaide’s north-west to support future growth in the area and improve odour management.

Fulton Hogan has been contracted to undertake the work, which is scheduled to begin in April 2018.

The $12 million project involves a refurbishment of the Largs North Wastewater Pump Station and the installation of a new 4.5km sewer main from the Largs North site to the Ethelton Wastewater Pump Station.

“The existing facilities, while currently fit for purpose, won’t be able to meet an expected increase in demand on our sewer network brought on by growing urban developments such as Newport Quays and new industry in the northern parts of the Le Fevre Peninsula,” SA Water’s General Manager of Asset Operations and Delivery, Mark Gobbie said.

“Our Largs North Wastewater Pump Station currently has the capacity to transport around 75 litres of sewage per second. The upgrade will allow this to increase by around 40 per cent to 106 litres per second.

“By upgrading the local network, we are reducing the likelihood of odour and overflow issues that new connections can cause, through improving the network’s reliability and environmental performance. We are ensuring we continue to support good public health outcomes through appropriate sewage management.”

The new sewer pipeline is being installed using a construction method known as directional boring, which requires less excavation and therefore results in a reduced impact on nearby residents and road users.

“We will soon be liaising with local property owners – including those along the preferred pipeline route – to ensure construction impacts, such as property access arrangements, are minimised,” Mr Gobbie said.

This project is part of SA Water’s commitment to meet community expectations by effectively managing odour, noise and environmental requirements for sewer infrastructure across the state.
