RSE = backwater level
Product solution 2
Proposed installation of a light liquid separator with a pumping station. The light liquid separator must be protected against backwater, as the calm water level in the tank is below the backwater level. Furthermore, the downstream sewer connection is higher than the outlet of the separator, meaning that the water must be lifted using a pumping station.
