The next stage of a $2.9 million project to upgrade the Mannum pump station will begin today.
SA Water will begin construction work to rebuild a 400 metre section of the pipeline near Chandler Avenue.
Service delivery manager Steve Rose says the new work will minimise the risk of flooding at the station, which has caused tens-of-thousands of dollars in damage over the past five years.
"Certainly it will reduce the risk of any problems at the pump station and it'll also provide a better stormwater drainage system for people around Mannum," he said.
"The work that we're doing should overcome all of that while also providing us with that security to the pump station."
Mr Rose says the project will also double the town's stormwater capacity.
"They're replacing the existing, relatively small diameter stormwater pipes with a much larger pipe that will take water from much further back," he said.
"It'll run right round the side of the pump station and increase the stormwater capacity around there by more than 100 per cent."
Mr Rose says the town's pump station is a critical link for Adelaide, as it provides water into the Kangaroo Creek, Millbrook and Little Para reservoirs.
Chandler Avenue will be closed for a month from today while construction work continues.
