Wilo-DrainLift WS 40 Basic is an automatically operating wastewater lifting unit in accordance with EN 12050-2 for backup-free drainage of sewage that does not contain faeces and that originates from building discharge points below the backflow level. The system can be installed in buildings as well as outside buildings in the same way as a plastic pump chamber in the ground. The system is ideally suited for applications that involve seasonal wastewater (such as at camping sites, weekend homes, etc.) or in regions where the ground does not freeze to very deep levels.
