Surplus rainwater from your roof or rainwater installation
will be conducted into the WISY soakaway unit‘s inbetween tank. When it
reaches a certain filling height, the water gets pumped out and is spread
over the earths surface.
Between two intervals the water has sufficient time to
seep. That way the ground pores have enough time to pull air again and
stay biologically active, so that the ground can easily accept further
infiltration intervals. Hold-up wetness is prevented.
The WISY soakaway unit can replace the drain connecting.
It can be used for collected roof water and as a overflow for rainwater
