South Australia’s housing pipeline is beginning to take visible shape, with more than 9,000 new homes now unlocked through the SA Government’s historic $1.5 billion investment in water infrastructure.
At the centre of the push is the state’s Housing Roadmap, unveiled in June 2024, which identified water and sewer capacity as one of the biggest barriers to new housing supply. Since then, SA Water has moved quickly, signing 261 development agreements with builders across the state to support 9,231 new allotments with essential services.
The impact is already being felt on the ground. At Riverlea in Adelaide’s north, at least 65 homes have been completed and are now occupied, an early milestone for one of the state’s largest greenfield developments. Across Adelaide’s northern and southern growth corridors, more than 30 kilometres of new water and sewer pipelines have been installed, laying the foundations for thousands more homes to follow.
Since SA Water’s infrastructure delivery program kicked off in September 2024, work has accelerated across multiple fronts. Capacity upgrades are underway in fast-growing areas including Angle Vale, Roseworthy, Riverlea and Onkaparinga Heights, with around 40 per cent of the total planned pipeline length already completed. On any given day, between 20 and 30 construction crews are active across 10 project sites, reflecting the scale and pace of the rollout.
Riverlea’s second development stage is now a major focus, with an additional 10 kilometres of trunk water mains being laid between Angle Vale Road and Kalara Reserve, via Robert Road and Petherton Road. This new infrastructure will connect into existing mains servicing suburbs such as Davoren Park and Virginia, while also linking to the recently upgraded SA Water storage tank at Elizabeth East. The tank upgrade increases water flow and improves system control, ensuring the network can support not only new homes, but future community facilities as well.
Nearby suburbs including Blakeview and Eyre are also set to benefit from the expanded network, which strengthens long-term water security while supporting continued residential growth across the region.
Premier Nick Champion said the investment marked a deliberate shift away from short-term thinking on infrastructure. “We refused to be yet another government that kicked the can down the road when it came to building water infrastructure,” he said, adding that the Housing Roadmap was designed to set South Australia up for sustained growth.
For developers on the ground, the momentum is already translating into tangible outcomes. Walker Senior Construction Manager Chris Emsley said the government-led infrastructure rollout had been critical to Riverlea’s progress. “The infrastructure rollout led by the South Australian Government has boosted serviceability at Riverlea, allowing us to unlock more land supply and deliver homes sooner,” he said.
Emsley also pointed to the broader community taking shape alongside new housing, with Riverlea’s first school under construction and The Palms Shopping Village progressing, helping to build a neighbourhood that offers more than just rooftops.
As major water projects continue and new stages come online, the collaboration between government and industry is beginning to deliver what many South Australians have been waiting for: more homes, delivered sooner, in communities designed to grow.
