Project summary
Unitywater is upgrading the Brendale Sewage Treatment Plant (STP), located on Cribb Road, Brendale.
The upgrade will increase the plant’s capacity to cater for the growing region and will improve the site’s odour conditions for surrounding residents and customers.
The current works are Stage 3 of the Upgrade, which includes essential improvements to the existing plant and also pipe interconnection works to provide for future population growth, help maintain water quality in the South Pine River, and bring about significant savings in capital expenditure.
This project is necessary due to the increasing population in the Moreton Bay region and the strain this has placed on the Brendale Sewage Treatment Plant (STP) which is now nearing capacity.
This defers the need for the construction of extensive, high cost infrastructure within the next five years
Stage 4 of the Upgrade will commence in 2016.

Project Background
The Brendale Sewage Treatment Plant is operating at peak capacity.
The plant currently treats a load of 41,000 equivalent persons (EP). While operating at loads above the original design loading of 30,000 EP, the plant is meeting licence in terms of effluent quality.
However, it is approaching a point at which connecting new customers will cause the plant, from time to time, to exceed its effluent quality environmental licence limits.
As the surrounding area becomes increasingly developed, encroaching on the plant, air quality monitoring and modelling indicate that odour control equipment will be needed to comply with the environmental licence.
Therefore the sewage treatment plant and the sewer network needs to be upgraded to provide compliant quality treatment services in the catchment of this sewage treatment plant.
Project Details
Immediate temporary (minimum five years) diversion of part of the flow from the Brendale Sewage Treatment Plant catchment to the Queensland Urban Utilities Luggage Point Sewage Treatment Plant catchment will reduce the load and give the Brendale plant some respite in the short term.
Arana Hills Rising Main Interconnection Project
The Arana Hills Rising Main Interconnection Project will provide for future population growth, help maintain water quality in the South Pine River, and bring about significant savings in capital expenditure.
This project is necessary due to the increasing population in the Moreton Bay region and the strain this has placed on the Brendale Sewage Treatment Plant which is now nearing capacity.
It eliminates the need for a $55 million infrastructure construction project to take sewage from a pump station at Arana Hills, through the Bunyaville State Forest Park and adjoining urban areas, to Unitywater’s Brendale Sewage Treatment Plant at Cribb Road, Brendale — this is in keeping with Unitywater’s commitment to prudent and efficient expenditure to minimise impact on our customers fixed water and sewage charges.
Unitywater’s most recent estimate of the population growth from new major developments in the area show that with the catchment diversion it will be possible to delay any upgrade of the Brendale STP until approximately 2016-2019.
A further upgrade of the Brendale Sewage Treatment Plant to ultimate load in 2019 is subject to the Moreton Bay Regional Council approving new development outside of the current service area.
