Driven by demand for critical supply chain upgrades and the development of major warehouse precincts, Melbourne’s southeast is continuing to experience significant expansion across the industrial sector.
Located in one of Victoria’s fastest-growing transport and logistics corridors, an upcoming development at Enterprise Industry Park, Pakenham, is set to contribute to the region’s logistics growth. This 12.1-hectare site is part of an expansive 27-hectare estate that accommodates large-scale industrial facilities for premium-grade warehousing, distribution, and transport operations.
Premier industrial projects benefit from the integration of scalable stormwater management infrastructure. Meeting requirements for developmental approval and compliance, assets such as On-site Stormwater Detention (OSD) tanks are essential components of sustainable development.
Stormwater detention systems aim to match pre-development hydrology by slowing, storing and gradually releasing incoming stormwater flows. These critical assets protect surrounding businesses, roadways, and drainage networks, ensuring that the impact of high-volume stormwater flows is mitigated and flood risk is reduced.
The development of OSD infrastructure is imperative for Australia’s growth corridors to effectively manage peak flows and protect downstream assets. These assets enable sustainable development, regulatory compliance, and environmental resilience.
MegaVault: OSD Solutions for Melbourne’s Growing Industrial Corridor
Atlan Stormwater’s 3.4-million litre MegaVault will rise to meet the OSD challenges of this sprawling development. Large industrial spaces contain extensive impervious areas with high volumes of stormwater moving quickly during heavy rainfall from surfaces such as roofs, hardstand, driveways and car parks.
A high-capacity, modular, precast concrete detention solution, MegaVault is ideally suited to these site conditions. Customisable and adaptable, its versatile design configurations ensured that access points, filter bays, weir walls and inspection channels could all be engineered to meet the available footprint.
A registered Australian design (Design no. 202315550), MegaVault is locally manufactured to meet ISO9001 standards. Each tank module is fabricated off-site in Atlan Stormwater’s precast production facilities, assuring quality and performance.
Independently engineered to exceed Australian traffic loading requirements, MegaVault delivers exceptional structural performance, which supports the operational requirements of industrial projects.
MegaVault’s robust structural strength enables underground installation, which maximises land yield and development opportunities for overhead civil and structural works, including site features such as driveways, warehousing and car parks.
A modular solution that is delivered ready to install, MegaVault ensured ongoing project benefits over conventional alternatives such as cast-in-situ tanks – with decreased exposure to wet weather delays, limited open excavation, and reduced site works and personnel risk.
MegaVault contributed significantly to project efficiency gains and the management of tight timelines. Rapidly deployed to meet strict construction schedules, the system’s quick installation enabled site works to continue with minimal disruption. Comparatively, a cast-in-situ solution would have required on-site formwork, pouring and curing, with multiple trades necessary throughout fabrication.
This system future-proofs the site and integrates seamlessly with aboveground development, ensuring available space for driveways, forecourts, and car park areas.
The MegaVault will be accessible from site-level access points and will reduce ongoing operational expenses. This allows for easy maintenance and enhances the cost-benefit of the system across routine maintenance, inspections, and clean-outs.
This installation demonstrates the integration of high-performance OSD tank infrastructure in high-growth industrial and logistics hubs.
Combined with Atlan Stormwater’s full-service project management, logistics, and coordination, this project marks the successful delivery of critical stormwater OSD infrastructure – built to perform for decades and ensure Joy in Water for future generations.
