Project summary
As part of its commitment to providing quality, reliable sewage treatment services, Unitywater has completed a major upgrade to the South Caboolture Sewage Treatment Plant (STP) located off Weier Road at Morayfield.
This treatment plant services Caboolture, Upper Caboolture, Morayfield and Bellmere.
The upgrade will enable the plant to treat the increasing volume of sewage being generated due to ongoing development in the region while also benefiting the environment and nearby residents by improving treatment standards.
Fast facts
| Location |
The South Caboolture STP is located near the Caboolture River off Weier Road at Morayfield. |
|
Benefits
|
- Improved quality of treated sewage that is released to waterways, contributing to an improvement in the health of the Caboolture River and Deception Bay; and
- Reduced propensity for odour emissions from the plant, reducing the impact of the plant on the environment.

| Completion |
Construction of the upgrade commenced on site in June 2010. The upgrade was completed in late 2011. |
| Funding |
$48 million. |
Project background
The upgrade is essential to ensure the plant’s ability to cater to the demands of this rapidly growing region. The plant currently treats eight million litres of sewage per day and is being upgraded to enable treatment of up to 16.3 million litres per day.
This will ensure the plant can accommodate the projected population growth to 2023. This significant upgrade will help sewerage services in the Caboolture-Morayfield district keep pace with development and population growth in the area.
Project details
The upgrade will improve sewage treatment standards and processes to reduce the plant’s impact on the environment. State-of–the-art treatment technology will be used to reduce the level of nutrients in the treated effluent and an odour control facility will be installed to reduce the possible discharge of odour emissions from the plant.
The upgrade will have the following benefits for the environment and nearby residents:
- a reduction in the nitrogen and phosphorous content of the treated sewage that is released into our waterways, contributing to an improvement in the health of the Caboolture River and Deception Bay; and
- minimising the propensity for odour emissions from the plant, reducing the impact of the plant on the environment.

Project Launch Update (PDF)
Local residents had the chance to see exactly what Unitywater engineers have been up to when the $48 million upgrade of the South Caboolture Sewage Treatment Plant (STP) was launched on 23 November 2011.
The completion of this upgrade is the latest addition to a growing list of achievements aimed at future proofing the region’s sewage systems.
It will improve the quality of the treated sewage that is released to waterways, ensuring Unitywater continues to meet and where possible exceed stringent environmental standards.
The upgrade will improve the efficiency and reliability of operations, resulting in significant cost savings.
Cost considerations have been paramount at all stages of project delivery, with the project management team electing to build on existing facilities and infrastructure, minimising the need to construct costly new tanks.
The South Caboolture STP upgrade follows the successful upgrade of the Burpengary East STP earlier in the year.
The upgraded plant, at Weier Road, services the Caboolture and Morayfield areas and will deliver a range of benefits to the community and the environment through improved equipment, technology and procedures.
