Tanks ain’t Tanks: the stormwater geocellular revolution

[Full article displayed on Engineers Australia’s website]

Open Cell StructureA unique patented plastic geocellular stormwater management system has been purpose designed to solve typical problems.

Sustainable surface water management is an integral part of the planning process. Urban designers need to consider managing the quantity as well as the quality of water that is discharged after it has been captured and stored. Plastic geocellular systems have been used for a number of years and are a widely accepted method of creating infiltration and detention systems. When properly integrated, they can enable stormwater discharge at a slower more natural rate. This protects the stormwater system, prevents erosion and increased flow to receiving waters. Pollutants, debris and sediment can be removed from the water so it can be harvested for reuse in parklands, sports fields, commercial agriculture and residential gardens.

A lack of accessibility for maintenance; handling difficulties and failure under load are common criticisms of plastic underground stormwater tanks.

ACO StormBrixx®, a unique patented plastic geocellular stormwater management system, is purpose designed to address these common problems. The modular structure provides 3-dimensional access for inspection and maintenance while retaining its structural integrity.

Easy To Handle Units

Specified for surface water retention, detention and infiltration, ACO StormBrixx® is a versatile system suitable for applications across all construction environments. It can be installed as a standalone solution or as part of an integrated Water Sensitive Urban Design (WSUD).

StormBrixx® HD is designed for heavy-duty applications and StormBrixx® SD is designed for medium duty applications.

Structural Integrity 
The StormBrixx® system has been independently tested for structural integrity and durability. The patented brick bonding and cross bonding feature provides a strong yet lightweight construction system that enables quick and easy installation of the tank.

Access, maintenance and low construction depth
StormBrixx® has an open cell structure that enables access for CCTV and jetting equipment. The whole system including the extremities can be inspected and maintained from a few access points. The unique pillar configuration gives a high void ratio of 95%-97%. A choice of access chambers is available for the system. The high void ratio has the added benefit of minimising the amount of excavation required to obtain a nominated design storage volume. The aggregate needed for backfilling is also reduced.

Simplified handling and logistics
The StormBrixx® stackable design simplifies delivery, site logistics and the installation of the tank, which reduces the carbon footprint of the system. The system can be assembled in a variety of ways to form an open bonded structure.

Additionally, compared with other  plastic crate systems, StormBrixx® is the quickest system to assemble in the industry. This reduces site costs significantly.


ACO can provide the expertise to assess the requirements of any project and offer product solutions to manage the surface water across the site. Project specific structural calculations, installation drawings and a bill of quantities are also supplied accompanied by high quality technical documentation. This service is offered free of charge and obligation.
