Functional description
“Ebb-flow” means that water is removed from the riding surface in ‘ebb’ mode (pump-out) and
fed to the riding surface in ‘flow’ mode (infeed).
When it rains, the excess water is pumped out fully automatically down to a previously
manually set setpoint level, which means that there is no prolonged moisture in the riding
arena.
If the riding surface is too dry, for example due to extreme sunshine and heat, water is
automatically fed to it up to the set setpoint level.

The actual water level in the shaft is measured via a fill level probe, which is built into the
compensation shaft, and forwarded to the control system. If the water level falls below the set
setpoint value and the set infeed hysteresis, a corresponding valve is opened.
From a water reservoir, water is now fed into the equalisation shaft and the drainage pipes.
From there the water is absorbed by the dry riding surface.
If the setpoint level is exceeded again, the valve is closed again.
