Public work stormwater management module ACO STORMBRIXX® TECHCUBE

for public spacesinfiltrationin-ground

Product overview
ACO StormBrixx® is a modular block rigole system composed of hollow plastic units used as an underground infiltration and retention installation. It combines infiltration and retention in a single system, relieves sewer networks, supports groundwater recharge and frees surface areas for other uses. In combination with upstream channel and pre-treatment stages, stormwater can be captured, treated and returned to the natural water cycle.

System lines

• Available in two main lines: MultiBrixx and PowerBrixx.
• Both lines are rated to load class SLW 60.
• Differences in installation depth: MultiBrixx up to ≈4 m, PowerBrixx up to ≈6 m depending on configuration.
• Full or half-layer executions possible; stackable base elements reduce transport volume.

Installation options

• As an infiltration system: the rigole is wrapped in geotextile to allow treated rainwater to infiltrate the subsoil over a broad area and promote groundwater recharge.
• As a retention system: the rigole is lined with a waterproof membrane to store rainfall underground and release it in a controlled manner to the sewer or receiving watercourse.

Product variants & technical data

• MultiBrixx 900 – height 1 layer: 924 mm; storage volume per layer: 656 l; storage coefficient: 97%. Suited for large-volume installations.
• MultiBrixx 600 – announced (coming soon).
• PowerBrixx 600 – height 1 layer: 614 mm; storage volume per layer: 426 l; storage coefficient: 95%. DIBt approval available; shallow surface installation possible due to low build-up height (from ≈330 mm).
• PowerBrixx 900 – height 1 layer: 920 mm; storage volume per layer: 650 l; storage coefficient: 97%. DIBt approval; suitable for very deep installations.

Stability, maintenance and inspection
The system architecture with stackable base elements and a keyed connection system provides high stability and structural strength. Installation in bond, inter-layer connectors and continuous access enable inspection and flushing in both longitudinal and transverse directions; the entire rigole volume is inspectable and maintainable.

Logistics & handling
Base elements, side walls and covers are optimized for stacking and halve transport volume compared with conventional systems. This reduces transport costs and CO2 emissions and speeds up on-site installation.

Manhole configuration and TechCube
An adapter for manhole construction provides direct economical access to the rigole; top parts are rotatable and telescopically adjustable (±30 mm) and watertight to about 0.5 bar. New: ACO StormBrixx® TechCube – an accessible technical chamber for all construction heights, pipe connection up to DN 600, usable as a throttling or pump chamber for maintenance and connections.

Documentation and application
Brochures as well as detailed installation and maintenance manuals are available for planning and installation. A planning tool (ProjectManager) and guidance on pre-cleaning, throttling systems and connection variants support norm-compliant and economical design.
