Precast Modular Onsite Stormwater Detention System |
Underground OSD Concrete Tanks
The Australian Tanks heavy duty trafficable detention systems consist of 7,000 litre or 12,000 litre rectangular tanks which are easily interconnected in multiples to create any volume quickly and very cost effectively.
Every system is certifiable, with increasing numbers of engineers incorporating our systems into their designs due to the structural integrity and multiple efficiencies the Australian Tanks solutions offer.
Every AT-7-TS and AT-12-TS system can arrive on site with weir walls, filtration, penetrations, trash screens, ladders, risers, manholes, drainage holes and orifice plates in place, ready for immediate install in the prepared site excavation. Importantly, all pf our systems are pre-cured with no further waterproofing required, ready for the site install to be completed in hours, not weeks , and can connected ready for backfill within the same day.
These systems are designed for small, medium, or large capacities and compete extremely favourably with alternative precast or built-on-site systems. Additionally, the lifecycle costs measure extremely well against alternatives as they are very easy to access, clean and maintain.

Why Choose Pre Cast Over 'Block and Slab'
Traditionally, OSD installers have heavily relied on ‘block and slab’ solutions to build OSD tanks and systems.
As the necessity for OSD systems has increased, so too has the reliance on those traditional labour and time-intensive block and slab detention tanks.
And, as with all demand increases, the costs have increased for slab work, block walls, suspended roofing and waterproofing.
More importantly the on site occupational health and safety requirements have made it more onerous for builders and contractors – this has also lead to increasing costs as well as the need for considerably more manpower and paperwork for Project Managers on site.
Builders and contractors are fast becoming busier in the ever-growing markets of Sydney, Melbourne, Brisbane and the Gold Coast – time becomes a major asset and lost time costs big money. Open excavations, delayed contractors, bad weather Australia regularly experiences, and the need to find additional components for block and slab systems can all combine to negatively impact building costs and efficiencies.
Over the past three years Australian Tanks has developed and refined
an EASY, FAST & COST EFFECTIVE solution to OSD Tanks
The AT7000 modular system can be installed with all On Site Detention requirements in place, delivered to site pre-cured and with no waterproofing needed, and ready for an install that takes hours, not weeks or months.
Our heavy duty trafficable detention system consists of one, or multiple, 7,000 litre anti-floatation rectangular tanks that are easily interconnected to create any volume quickly and cost effectively. With a lower internal height, the AT7000 tank is perfect for shallow requirements of many small On Site Detention systems.
Every AT7000 system can be engineer certified, with increasing numbers of engineers incorporating our system into their OSD tanks designs. The systems can arrive with weir walls, filtration, penetrations, trash screens, ladders, risers, manholes, drainage holes and orifice plates in place and can be installed and connected ready for backfill within the same day.
These systems are designed for small to medium capacities and compete extremely favorably with alternative precast or built-on-site systems. Additionally, the lifecycle costs measure well against alternatives as they are very easy to access, clean and maintain.
Due to the massive success of the modular system and the significant civil engineer support of the AT7000 system, Australian Tanks was proud to recently launch the AT12000 system – a larger and more robust 12,000 litre modular tank that can achieve even more substantial and deeper detention solutions in the same EASY, FAST AND COST EFFECTIVE way at an even lower per litre price than the AT7000.
If you are interested in finding out more about either the AT7000 or the AT12000 systems, please call one of our civil design and business development specialists so they can assist you to develop a CAD driven design for your OSD system.
Australian Tanks also manufacture larger systems consisting of 15,000 – 20,000 – 25,000 and 45,000 litre inter-connectable tanks. These systems are designed specifically for large capacities and to compete with in-situ head to head; achieve a substantial detention system in 1–3 days instead of weeks.
As with all of our products, this comes with heavy duty traffic load ratings in accordance with Australian Standards design codes (AS5100.2) and can be backfilled and bear traffic immediately. No downtime while curing.
Thanks to the team at Australian Tanks for getting this key piece of site infrastructure in place in such a short space of time despite rain and allowing the site access back in use quickly. Well done to our BUILDUS team for getting on with the job.
