Advantages of DRAINMAX systems at a glance
DRAINMAX systems combine sedimentation, filtration, storage, and throttling in a single compact unit – without separate shafts. This saves space, reduces costs, and impresses with its efficiency.
Integrated cleaning, flushing, and inspection shafts, as well as flushable fabric, ensure long-lasting functionality and ease of maintenance. The single-layer construction enables fast, cost-effective installation.
DIBt-certified up to 60 tons – suitable for traffic with access roads and parking areas. I-CONNECT enables digital remote monitoring of fill levels, sludge levels, and maintenance recommendations in real time.

Simple - Modular - Well-thought-out
Every system starts with the DRAINMAX basic package – and can be individually expanded:
- Basic package: Basic module for all applications.
- Storage system: Combine the appropriate package with identical volume.
- Retention system: Add a throttle for controlled discharge.
- Modular extensions: Flexible add-ons for penetrations and inspection chambers.
Note: Distribution pipes and fill material are not included.
Ideal for planners, architects, and building owners – with DRAINMAX, you rely on an intelligent, low-maintenance, and durable rainwater management system.
