Controlled discharge of stormwater

A binding principle for both dynamic and static solutions is that the peak load must be as low as possible to prevent any disruption of the water ecosystem and avoid a water overload.

When emptying storage facilities or storm sewers, the discharge rate is meant to be relatively low. A good way of controlling this discharge is the use of a vortex valve on the discharge side. The vortex valve shafts developed by FRÄNKISCHE together with UFT are flow limiters to define the discharge rate from overflow tanks, storage tanks and stormwater pipework systems to a precalculated and defined maximum discharge capacity.

Where sufficient space for storage cannot be created in existing paved areas or where infiltration is not possible, the local discharge requirements stipulate how much water can and may be discharged from the area. For new projects, sufficient storage (with or without infiltration) must always be assured.

FRÄNKISCHE has various shafts with integrated vortex valves – we can offer the right solution for your application.
