A $5-million upgrade of the Port Lincoln sewer network will start next month, increasing the network’s capacity and improving its reliability and environmental performance.
SA Water will install about four kilometres of new sewer main under Wingard Terrace, Marina Drive and St Andrews Drive, and duplicate a key connection into the Port Lincoln Wastewater Treatment Plant at Billy Lights Point.
SA Water asset operations and delivery general manager Mark Gobbie said the new mains would build extra capacity into a tight area of the network.
“The Port Lincoln wastewater network has 143 kilometres of sewer main with 20 sewer pumping stations helping send the sewage towards the treatment plant,” Mr Gobbie said.
“With five of those pump stations currently pushing sewage into one large main, the addition of the new sewer main will overcome existing capacity limitations and set the network up for future growth.”
Construction will be led by South Australian company S.E.M. Utilities, with support from local contractors, and is expected to be complete by October 2018.
Mr Gobbie said SA Water would work with the contractor to minimise contruction impacts and would continue to keep the local community updated.
“For the safety of our workers and the community, traffic management including lane restrictions and detours, will be in place during the project.
“Advance notice will be provided to local residents and businesses whenever night or weekend work is required, or if any property access is temporarily impacted.”
SA Water will continue to work closely with local stakeholders including the council on additional planned sewer network upgrades in the area, including within the wastewater treatment plant site.
The sludge management upgrade at the treatment plant is still in development phases, with construction estimated to begin in the first quarter of 2019.
