Practical example I

The Hydrass Valve (2)

At low water levels the gate remains in the vertical position. This causes the wastewater upstream to back up and increases the water level h0.

So long as the wastewater pressure is greater bellow the rotational axis of the gate than above it, the gate will remain closed and continue to back up the wastewater.
