DRAINMAX, one system - numerous applications

Our unique DRAINMAX tunnel system is the solution for numerous applications, such as rainwater infiltration and retention, the storage of rainwater, drinking water, or firefighting water, infiltration of wastewater from sewage treatment plants, and subsurface irrigation. 

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.
