Flow Control Chamber DN 1000

Controlled storm water discharge

The DN/OD 1000 Flow Control Chamber is a flexible, monolithic and sealed chamber system that can be used whenever the flow of storm water needs to be controlled as it is discharged into the public sewer system. For example, this may be the case after it has been through a rainwater attenuation or soakaway system.

The Flow Control Chamber comes with a pre-drilled, built-in throttle element as well as a socket (DN/OD 160 to 500). An internal overflow prevents system failure in case of a heavy rainfall event or if the throttle element jams. Below the inlet and the dosing element is a sedimentation zone, which can easily be cleaned as necessary.

Construction height, including the cover, can range from 1.0 m to 5.0 m.
A factory-fitted stainless-steel ladder (optional) facilitates access. Available covers include a plastic telescopic option as well as a concrete cover slab for holding common (Germany) 625 mm chamber covers in a range of load classes (up to D 400).

The advantages in practice:

  • No deposits thanks to smooth surfaces
  • Highly resistant to chemicals
  • Suitable for large catchment areas (depending on inlet socket diameters)
  • Built-in respectively permanently integrated seal system
  • Up to load class D 400
  • Manufactured according to individual requirements
  • Easy installation thanks to low weight
