Project Support: Comprehensive Assistance for Successful Stormwater Projects
ACO offers project specific services designed to make specification, ordering and installation easy.
Having a straightforward process can drastically streamline project workflows for those dealing with complex stormwater detention and retention systems. ACO simplifies these steps by providing expert guidance through each phase. This saves time, reduces errors and allows clients to focus on other aspects of the project.

The services deal with each project’s unique, hydraulic, structural, maintenance and spatial requirements.
These factors are critical in creating a reliable stormwater infrastructure design. No two projects are alike, which is why careful assessment of these requirements is essential to achieving optimal results. From analysing complex hydraulic and structural needs to planning for stormwater maintenance and inspection, ACO carefully evaluates every detail to provide solutions that meet the specific demands of each project.
The service is fully documented and is offered free of charge and obligation.
Comprehensive documentation is crucial for successfully implementing and managing stormwater detention and retention systems. It provides a clear framework and helps all stakeholders access the necessary details for effective installation and long-term performance. This thorough approach also streamlines future stormwater system maintenance and inspection.
ACO offers these services free of charge and without obligation because we are committed to giving every project the best possible start. By removing cost barriers, we empower clients to make confident decisions and select the most suitable stormwater infrastructure design without hesitation.

askACO to Determining the Right Tank Size for Your Project with ACO
Hydraulic design deals with surface runoff as well as the temporary storage of water in storm events. The objective is to reduce the volume, speed and frequency of surface water runoff. Factors will be site specific and calculations for hydraulic design may be undertaken using locally accepted and approved methods.
ACO can assist in sizing up a StormBrixx tank for on-site retention, detention or infiltration based on your preferred tank dimensions or storage volume required. We highly recommend this service, particularly for stormwater retention system projects, where maximising storage capacity and preventing overflow is crucial.
Or you can Do-It-Yourself using the StormBrixx Configurator program. This tool allows you to input your project specifications and generate an optimal configuration for your tank system — whether it is an underground water retention system or another type of solution.
Either way, you will receive a summary of the recommended StormBrixx tank dimensions, a bill of material listing all the tank pieces, access and pipe accessories including an approximate assembly time to build the tank. ACO can also calculate the amount of geomembrane and/or geotextile required to wrap the tank.
askACO to Ensuring Structural Integrity of the ACO StormBrixx®️️ System
Structural design considers the load bearing capacity of the ACO StormBrixx® system to ensure it can safely carry the loads it will be subjected to. The initial decision must be made on the type of system required ‑ retention, detention or infiltration and then the design parameters shown below should be considered.
- Soil type
- Vertical loading (including site traffic movement)
- Groundwater
- Depth of cover and total installation depth
- Surface finish
- Horizontal loading
Consideration must be given to the maximum surface deflections allowable for the pavement above the tank. Although excessive deflections may not lead to tank failure, they will cause localised pavement deterioration. ACO can provide structural deflection results for specific live loads. Creep (long term deflections under permanent dead loads) should also be investigated to ensure the durability of the tank.
Structural calculations should be carried out using methodology detailed in CIRIA C680 – “Structural design of modular geocellular drainage tanks”.

ACO will provide general installation drawings, addressing key requirements.

askACO to Maintenance and Inspection Recommendations for Your Tank
The frequency of a maintenance procedure for the tank will be determined by the inspection regime. A recommendation is not less than twice-yearly inspections, and during the first year after every significant storm event.
In order to minimise silt build-up, ACO recommends the use of pretreatment systems upstream of the retention/detention system.
askACO to Customised Geomembrane and Geotextile Solutions
ACO can supply each tank with a correctly sized geomembrane or geotextile wrap specific to the needs of your project. Impermeable geomembranes are for retention and detention applications. Permeable geotextiles are for use in infiltration applications.

askACO to Sizing ACO StormBrixx®️️ Tanks with STORMupdated
ACO StormBrixx® tanks can be sized using the STORMupdated programme by Cleanstormwater. STORMupdated is a free online WSUD (water sensitive urban design) and OSD (on-site stormwater detention) compliance tool for use by councils and consultants.
Reports from STORMupdated can be submitted to local government / councils along with the development application (DA) to demonstrate compliance with local guidelines.
Benefits of Having a Properly Sized Tank From the Get-Go
- Early Planning Saves Time and Money — Correctly sizing your stormwater retention system from the start reduces costly changes later in the project.
- Prevents Overflow and Flooding — A well-planned underground water retention system effectively manages stormwater during peak flow events.
- Compliance and Efficiency — Getting the dimensions right for on-site retention systems helps meet regulatory requirements early and avoid compliance issues.
- Optimised Space Utilisation — Accurate sizing maximises storage capacity and ensures that valuable site space is used efficiently.

These benefits apply to other applications, making proper planning and sizing critical to successful stormwater management solutions.
