Eighteen kilometres from the Brisbane CBD, a new 4.6-hectare industrial site purpose-built for manufacturing and concrete reinforcement is taking shape in the rapidly developing northern suburb of Brendale.
Located in the City of Moreton Bay, the fifth highest growth LGA in the country, the suburb includes a mix of industrial and residential zoning. Stormwater infrastructure provides critical protection for Brendale’s local waterways, such as the Pine River and the receiving marine environments of Moreton Bay.
Key stormwater management criteria include compliance with council-based Water Sensitive Urban Design (WSUD) requirements and Queensland State Planning Policy (SPP).
The management of high-volume stormwater flows generated by large impervious areas in the site’s hardstand, car parks, and roofs is essential. These strategies ensure that the adverse impacts of runoff on downstream waterways, properties, and infrastructure are minimised.
Water Quality & Quantity:
MegaVault, AtlanFilter & StormSack
Expansive industrial sites present unique stormwater challenges, including high flow rates, mixed pollutant loads, and heavy vehicle traffic. These applications require a robustly engineered approach, with load rating, design life and ease of maintenance highly valued to ensure seamless business operations and reduced operational expenditure.
Meeting these challenges, Atlan Stormwater provided a range of assets for the site, including StormSacks, AtlanFlow HDPE Pipe, and a 2.5 Megalitre MegaVault.
The MegaVault is our locally manufactured precast OSD tank system (On-site Stormwater Detention) for high-volume applications. Providing flood mitigation, stormwater detention acts as a buffer that slows peak flows by detaining and slowly releasing incoming stormwater.
An efficient 110-module MegaVault with 2.7 metre internal height met the required detention volume in the available site footprint. Installed underground to maximise developable space, the system’s trafficability makes it suitable for applications under pavements, driveways and car parks trafficked by heavy vehicles.
Incorporating modular design principles, the MegaVault is delivered ready to install, minimising excavation times and expediting project timelines, particularly compared to cast-in-situ alternatives.
StormSacks will service water quality across the site, providing at-source pollution removal which includes the capture of gross pollutants, sediment and particulates. A SQIDEP verified device (Stormwater Quality Improvement Device Evaluation Protocol), the StormSack will minimise the development’s environmental impact and support sustainable outcomes.
Achieving SQIDEP verification in late 2024, StormSack has tested removal efficiencies of 100% Gross Pollutants (GP), 45% Total Suspended Solids (TSS), 47% Total Phosphorus (TP), and 25% Total Nitrogen (TN). This at-source Gross Pollutant Trap (GPT) can be deployed in grated inlet pits in driveways or hardstand to capture pollutants close to surface level.
By using StormSack to capture contaminants, the accumulation of pollution in downstream OSD assets will be prevented – reducing maintenance overheads and enhancing service life. Incorporating cost-effective, low-impact design principles, the StormSack is easily accessed for monitoring and maintenance without specialised equipment.
From MUSIC modelling and asset selection to minimising lead times and providing site-specific drawings, the Atlan team supported project stakeholders through all stages of planning, design, and delivery. Preserving the integrity of Brendale’s local waterways, these generational assets and comprehensive stormwater services will protect Joy in Water for future generations.
