Aldi Distribution Centre Truck Wash Bay Brendale, Qld

Beavis & Bartels Pty Ltd

The Challenge

Project required 150,000L water storage for reuse at the Aldi Brendale distribution centre truck wash bay.

  • The water storage was to be located under the entrance to the truck wash facility, so it would incur loads from semi-trailer traffic.
  • Spatially there were footprint restrictions due to an existing retaining wall footing and large stormwater pipe.
  • The site had the potential for high ground water conditions.
  • WHS was specified to be of the utmost importance for the project

The Solution

  • 6 x 25,000L tanks were supplied as an inter-connectable system to fit within the available foot print.
  • The tanks have a 20kPa load rating, trafficable by a fully loaded semi-trailer and have the Australian Tanks signature square anti-floatation base.
  • The tanks weight (11.2T), soil loading on the tank lid, and on the anti-floatation ‘wings’ provide enough ballasting to resist any hydrostatic uplift forces, even if the tanks were pumped empty and in 100% saturation.
  • To provide the best WHS benefits, all penetrations were completed in the Australian Tanks factory, reducing the time spent by others on-site in an excavation.
  • Additionally, low level tank connection pipework stubs were sealed into the tanks in the factory, with a ‘Gibault’ style coupling provided to connect them on-site.
  • On-site when the square anti-floatation bases came together, the connection pipework stubs aligned and the coupling was simply slid across and tightened, completing the tank connection in minutes.
  • The efficient method of connecting the tanks reduced the time required for someone to be in the excavation providing additional WHS benefits.

The Results

  • 150,000L reuse system was installed within one day
  • Completion just days prior to a major wet weather event in Brisbane
  • Significant on-site efficiencies were gained by using a precast solution over a built on-site tank, particularly in completion time and WHS due to having a one-day install
  • One day installation benefit was not having an open excavation for an extended period
  • Reduced the time spent that workers were required to be in the excavation


  • Six (6) x 25,000L Australian Tanks precast anti-floatation concrete tank
  • 20kPa load rated, trafficable by a fully loaded semi-trailer based on the SM1600 design load ratings
  • Tanks supplied with all penetrations completed in the factory, providing on-site efficiencies and WHS benefits
Residential development – Denman Prospect ACT
A unique hybrid installation combining both water retention and water detention.
Coomera Town Centre South
Australian Tanks teamed up with Civil 360, Golding Contractors and Foxwellat the new Coomera Town Center South, 64 Foxwell rd, Coomera.
SJ Higgins for McDonalds Australia
McDonalds Australia Limited engaged SJ Higgins to construct two new McDonalds Restaurants in Oxenford and Chermside Park. Torque Civil (Oxenford) and Blue Frog Plumbing (Chermside) were appointed to provide the Hydraulic Packages. Both stores had Humes Rain vaults and Volume Filters as part of the package. Australian Tanks were engaged to provide an equivalent solution to these rain harvesting requirements specified in the plans.
John R Keith Group
John R Keith (Plumbing Contractor and our client) approached Australian Tanks to offer an alternative solution to the more expensive extra heavy duty tank option which was specified in the Hydraulic plans. The original option in the plans also showed (1) a combination of transport cost challenges, (2) requiring additional work to get the initial tanks rated to take heavy traffic loads, and (3) the need to have considerable cover over the tanks to meet Invert Levels for the site.

Civilivic, Stormwater Detention
Situated beneath a shared driveway, this 42,000L stormwater detention site presented multiple requirements in project time and cost efficiencies. The site could not be shut down for two weeks for an in-situ solution, therefore an anti-floatation and heavy duty trafficable Australian Tanks precast solution with a one-day install time was the most efficient process available.
