Rainwater, grey water and black water that occurs below the backflow level must be fed into public sewers via an automated lifting system without backflow. The principle applies to single-family houses as well as to public buildings used for commercial and industrial plants.

The wastewater flows into the collecting tank of the lifting plant via one or more inlets. When the wastewater in the collecting tank reaches a specific level, the pump switches on automatically and the wastewater is pumped into the sewer via the pressure line.
