SA Pipeline Work Paves Way for 40,000 Lots

South Australia is delivering the first water pipelines to Adelaide’s north under a $1.5-billion investment in housing infrastructure. 

The Government wants to unlock up to 40,000 allotments across the state, and water and sewer infrastructure is a key part of its Housing Roadmap to achieve that.

As part of the $419-million first tranche of funding, more than 3000m of new trunk water main will be laid underneath Angle Vale Road and Supple Road at Virginia, clearing the way for development of Adelaide’s northern growth sector. 

South Australia will receive $67.4 million from the Federal Government’s Housing Support Program to fund the infrastructure and to allow water and sewer upgrades. 

The SA Government is bringing in construction partners McConnell Dowell and Diona, who entered a joint venture to secure SA Water capital works projects in 2020. 

The partners will install 750mm-diameter trunk water mains, weighing three tonnes apiece These rubber-coated steel pipes will connect to SA Water’s existing network. 

Crews have begun laying the pipes from the southern end of Supple Road towards Angle Vale Road, with a further 2600m of trunk water main earmarked for installation beneath Midway Road. 

▲ As part of its Housing Roadmap, the SA Government has committed to 4817 public housing homes by 2026, including upgrades to existing homes.

This first stage of enabling work is expected to be completed in early 2026.

SA’s Housing Roadmap introduced in June this year outlines a series of measures to speed up housing development in the state, aiming to streamline the code amendment process and resulting land division.

The Government is pushing to lower the timeframe for turning an empty block of land into a housing development to 36 to 63 months, compared with 54 to 75 months under the current system.

It has also undertaken what it said was the largest land release in the state, and plans to abolish stamp duty on new homes.
