The Atlan MegaVault is our locally manufactured, precast concrete On-site Stormwater Detention (OSD) system for water quantity management in medium to large-volume applications. A registered Australian design, the MegaVault enhances depth capability with superior product quality and full structural certification.
Featuring modular design efficiency, fabrication to ISO9001 quality standards, EPD certification and versatile configurations, the MegaVault is available in customisable footprints with up to 3.0 metre internal height. Modules of these systems are reconfigurable, which allows the ease of integration of site-specific design requirements such as maintenance access points, filter bays, weir walls, and inspection channels.
Key benefits of modular precast concrete tanks compared to cast-in-situ alternatives include construction efficiency, resiliency to poor weather, design flexibility, and faster installation.
Fabrication is an essential difference between these two types of OSD tanks. Precast modular solutions are fabricated off-site in a controlled factory environment – and their production is optimised in dedicated facilities that ensure consistent structural performance, engineering quality and reduced risk of defects.
In comparison, cast-in-situ systems require formwork, pouring, and curing with multiple trades on-site throughout their fabrication – which exposes projects to potential setbacks such as weather delays.
Consequently, modular precast tanks result in faster project timelines than cast-in-situ methods. Delivered ready to install, turnkey solutions like the MegaVault ensure seamless installation, reduce labor times, and minimise the duration of open excavations.
Inspired by cathedral style OSD architecture and civil design principles, the MegaVault’s modular system delivers cost-efficiency, scalability, and flexibility to suit a diverse range of catchment sizes and site footprints.
Built for the Future: 100-Year Design Life
Establishing the MegaVault as a premier water quantity solution for large infrastructure projects, our latest designs have incorporated 100-year design life engineering to enhance the system’s robust structure, loading capabilities and durability.
These systems are engineered to tackle OSD scenarios on critical infrastructure projects – such as rail, metro systems, airports, and ports.
Representing a generational approach to precast stormwater infrastructure, the 100-year design life MegaVault incorporates structural advances and reinforcements that build on the foundations of our standard MegaVault system.
We look forward to bringing you our upcoming case studies on our 100-year design life MegaVault, and exploring the ways they can be deployed in civil infrastructure projects with design requirements for strength, durability, and service life.
