Work is set to commence on the build of two wastewater pump stations to connect around 2,500 properties in Angle Vale, north of Adelaide, to SA Water’s sewer network.
The works will also include the installation of around 5km of sewer main.
Sewage from residents in new local housing developments currently discharges directly into a temporary tankering facility, before being transported to SA Water’s Bolivar Wastewater Treatment Plant.
SA Water’s General Manager of Customer Delivery, Kerry Rowlands, said the planned upgrade will provide several benefits for the community and environment.
“Once connected to our existing network, the new sewer main will assist to better manage sewage flow and odour, and cater for forecast population growth in the area,” Ms Rowlands said.
“We understand that odour from the tankering facility is of particular concern to residents, and we assure them that this infrastructure will be decommissioned and removed, once the new system is operational.
“Over the past six months, we have undertaken extensive engineering and design work for the complex upgrade, and on-ground assessments along Heaslip and Curtis Roads are underway – including geotechnical investigations, surveying and service locations – to inform pipe design and alignment.
“Following support for the project confirmed in June by our independent economic regulator, we expect to start the sewer upgrade in coming months, subject to required development and environmental approvals.
“After mobilising to site, our lead contractor, Fulton Hogan, will begin trenching and directional drilling to lay the underground pipes, before constructing the pump stations, with the entire project scheduled to take around eight months to complete.”
As part of the project’s planning phase, SA Water is working with the City of Playford to limit construction impacts on the local community and people travelling through the area.
“This includes the timing of construction hours, aligning our project with works planned by the council, and putting measures in place to minimise dust, noise and disruption to traffic and property access,” Ms Rowlands said.
“We will continue to provide project updates to local residents and businesses as more details are confirmed.
“Once the new section of pipe is connected and transporting sewage from local properties, we ask our customers to do their part in keeping the network flowing, by only flushing the three Ps – pee, poo and (toilet) paper – down the toilet, to avoid sewer overflows or blockages.”
