In any drainage system, the flow control is a vital component of the design.  

Its performance ensures that the amount of surface water flow from a development complies with regulations, and it also dictates the amount of storage that is needed to store any excess flow volume, which in turn can significantly affect installation and overall project costs.

To help engineers meet specific site conditions when designing Sustainable Drainage Systems, Hydro International has developed a range of design objectives for its Hydro-Brake® Optimum.
