Bellara Reservoir Renewal Progresses as Morayfield Joins Seven-Site Program

Bellara’s water reservoir on Bribie Island is undergoing a roof replacement, while Unitywater continues assessing the work required at an existing reservoir in Morayfield.

The Bellara project began in October 2026 and is scheduled for completion in April 2027, according to Unitywater’s 9 November announcement. The reservoir supplies nearly 23,000 residents.

Bellara roof replacement targets April 2027

The roof replacement is intended to help prevent potential contaminants from entering the reservoir and extend the life of the existing water storage facility. Bellara is one of seven reservoir locations included in Unitywater’s latest renewal program. The other sites are Pomona, Coes Creek, Morayfield, Cashmere, Eatons Hill and Ferny Hills.

The projects form part of Unitywater’s $500 million network-wide infrastructure replacement and renewal program. The utility estimates that the seven reservoir projects collectively support more than 155,000 residents across its service region.

Unitywater’s announcement identifies roof replacement as the confirmed work at Bellara. It does not provide a separate cost for the local project.

Water-quality concerns remain separate from refurbishment

Unitywater also publishes information about water-quality concerns raised by some Bribie Island residents, including reports of itchy or dry skin. On its Bribie Island water-quality page, the utility said the supplied water remains safe and compliant with the Australian Drinking Water Guidelines.

Unitywater said it continuously monitors water quality through analysers at the Bellara reservoir and collects weekly laboratory samples. It also reports conducting additional sampling at Bellara following water-quality concerns, with readings remaining within the guideline parameters.

The published information does not establish that the reported skin complaints were caused by drinking water or that they prompted the reservoir roof replacement. The utility describes the refurbishment as an infrastructure renewal intended to protect the stored water and extend the asset’s service life.

Morayfield reservoir still needs further assessment

Morayfield is also included in the seven-location announcement, but Unitywater has not confirmed a construction schedule or final scope for its existing reservoir.

The utility says investigations with delivery partner Downer are continuing to determine the upgrade requirements. No local completion date or detailed list of works has been published.

The assessment comes as Morayfield records strong population growth. The Australian Bureau of Statistics reported a 15 per cent growth rate for the Morayfield statistical area in 2024–25, one of the highest rates recorded in Greater Brisbane.

The City of Moreton Bay also published a planning update on 29 October 2026 confirming that Morayfield South is projected to accommodate up to 26,000 residents over coming decades. Planning scheme amendments commenced on 2 November, establishing a framework for future roads, schools, community facilities and environmental corridors.

These population and planning figures provide regional context, but neither source establishes that Morayfield’s growth directly prompted the existing reservoir renewal assessment.

Pine Valley is a separate new reservoir project

Morayfield is also the location of Unitywater’s separate Pine Valley Water Supply Project. The $64 million project includes a new 15-megalitre reservoir at Jacko Place and more than eight kilometres of water pipeline. Construction began in January 2025, with completion expected by mid-2027, subject to weather and site conditions.

Unitywater says the new infrastructure will support Caboolture West, Morayfield and Narangba, where more than 100,000 additional residents are expected over the next 20 years.

The Pine Valley facility is a new reservoir, not the existing Morayfield reservoir listed for further investigations in the November renewal announcement.

Unitywater has not published a construction timetable for the existing Morayfield reservoir. Its next confirmed project details will need to establish the work scope and expected delivery period.
