Guideline according to standard DIN1989-1

With connection of the storage overflow to a mixed water sewer or higher infiltration drainage a lift station must be used according to DIN1989-1. The lift station will supply the water above the backwater level by immersion pump after the maximum level is achieved. Attention must be paid so that the pressure line lies below the frost depth even in areas of elevated backwater. The backwater level can also lie within the home. The dimensioning of the pump is determined according to DIN1986-100 with r_(5,100). The immersion pump can be installed in the storage, eliminating the need for an additional pump shaft.
