Concrete manhole FLOW CONTROL CHAMBERS

Marshalls CPM has designed this off site solution precast chamber to accommodate a requirement for control stormwater events at different peak levels i.e. 1 in 20 or 1 in 50 year storm events etc. To control these storm events the concrete chamber can be pre-fitted with a Hydro-Brake Optimum®, Hydro-Brake® or Orifice plate on either a headwall or weir wall. Marshalls CPM in an innovative joint venture with Hydro International has introduced a series of easy to install pre-formed Hydro-Brake® chambers that incorporates a pre-fitted Hydro-Brake® or Hydro-Brake Optimum®. This chamber has been designed to enable the contractor to install the flow control chambers in a fraction of the time it takes using conventional methods. Marshalls CPM has a comprehensive range of chambers to suit most flow control chamber requirements, with a range that starts from 1200mm up to 4000mmm diameter.
