Surge manhole [FI-Funke]
The surge manhole "FABEKUN system" consists of a 1.0 m high precast concrete section that is placed on an ordinary manhole base.
It contains two DN 150 water inlets at the top and a large outlet at the bottom, along with a ventilation/overflow pipe.
The flush valve is located in a chamber bellow the outlet opening, and is activated by a floating ball that rises and sinks with the water level in the manhole.
