Stormwater attenuation and infiltration

Storm bricks


ACO StormBrixx is a unique and patented plastic geocellular stormwater management system. Designed for surface water infiltration and storage, its versatility allows it to be used in applications across all construction environments as a standalone solution or as part of an integrated sustainable urban drainage (SuDS) scheme. The award-winning system addresses the fundamental requirement of access and maintenance for SUDS Approval Boards (SABS) and water companies, whilst retaining the structural integrity of the installation. The open cell structure permits completely free access for CCTV and jetting equipment which allows the whole system, including all the extremities, to be inspected and maintained from just a few access points.





Surface Water Flow Controls

surface water flow controls


ACO's range of flow control systems are designed to regulate stormwater flow before it discharges into the water course or sewer networks ACO Q-Brake Vortex flow controls and ACO Q-Plate orifice plates are capable of regulating any flow for surface water applications and can be used in conjunction with retention and attenuation systems, such as ACO StormBrixx, as an integrated sustainable urban drainage (SuDS) scheme.





Stormwater Treatment
