Wastewater infrastructure in Burpengary is being upgraded to accommodate the equivalent of 4,378 additional homes over the next 30 years, as Unitywater prepares its network for further residential development across Moreton Bay.
The houses may not be built for years, but some of the infrastructure needed to service them is already being upgraded.
In Burpengary, Unitywater is improving a wastewater pump station on Adsett Road and its connection to a sewer rising main at Springfield Drive. The work will help move wastewater from future residential development through the network to treatment facilities, with the additional capacity intended to accommodate approximately 4,378 new homes over the next three decades.
It is one of several projects now underway across Moreton Bay, where established suburbs and emerging residential communities are placing different demands on the region’s wastewater system.
Unitywater Executive Manager Sustainable Infrastructure Solutions Mike Basterfield said the Burpengary works were being undertaken with longer-term growth in mind.
“The upgraded pump station on Adsett Road, Burpengary and sewer rising main connection to Springfield Drive, Burpengary will push wastewater from about 4,378 new homes in the next 30 years into the wastewater network and through to our treatment plants to be safely treated and returned to the environment,” he said.
Other wastewater rising mains in Burpengary are also being upgraded to improve network reliability and reduce the risk of overflows.
The first stages of Unitywater’s wider Moreton Bay programme began in September 2026, with construction scheduled across several locations until June 2027.
Morayfield South’s Much Bigger Growth Picture
The investment comes as planning continues for Morayfield South, where thousands of additional homes are envisaged over the longer term.
City of Moreton Bay planning documents identify the Morayfield South Emerging Community Area as a major future residential growth area covering approximately 900 hectares.
The broader planning vision provides for approximately 9,800 dwellings and an eventual population of around 26,000 people, alongside the roads, community facilities, open space and essential services needed to support new neighbourhoods.
Those figures describe the anticipated scale of Morayfield South’s development. They are separate from Unitywater’s projection of 4,378 homes associated with the Burpengary pump station upgrade, and the utility has not identified how many Morayfield South properties, if any, will be directly served by that particular project.
Morayfield South is, however, specifically included among the areas expected to benefit from another part of Unitywater’s latest infrastructure programme.
At Hercules Road in Kippa-Ring, the utility is upgrading a gravity wastewater main and pump station, installing approximately 400 metres of new pipe and constructing new maintenance holes.
Unitywater says the improvements will support new development in Morayfield South, Newport, Rothwell and Kippa-Ring.
The connection illustrates how infrastructure serving future residential areas may be located well beyond the boundaries of those developments.
Elsewhere in the region, Unitywater is installing a new overflow structure in Caboolture to help prevent wet-weather wastewater overflows from affecting the community and surrounding environment.
Additional works include improvements to a gravity wastewater main in Strathpine and enhancements to low-pressure sewer systems on private properties in Donnybrook. Those improvements involve new flushing points and valves to make ongoing maintenance easier and help wastewater move reliably through the network.
Unitywater’s delivery partner Abergeldie is undertaking the construction programme, which is expected to finish in June 2027.
The utility has not specified individual completion dates, traffic arrangements or possible service interruptions for the Burpengary and Caboolture work zones in its latest announcement.
The works form part of Unitywater’s $2 billion investment in water and wastewater infrastructure over five years across Moreton Bay, the Sunshine Coast and Noosa. That figure covers the broader service region rather than the cost of the projects announced this week.
For communities around Burpengary and Morayfield, the immediate changes may be largely confined to construction sites and underground infrastructure. Their longer-term importance lies in ensuring that wastewater services can accommodate new development while continuing to operate reliably for households already connected to the network.
