Waste water lifting units. Short explained.

This is how waste water lifting units work

Preventing backflow under all circumstances is crucial when draining waste water. Backflow occurs when waste water flows from the sewer back into the sanitary piping of a premise’s drainage system and, with that, into the building. It only takes seconds for large amounts of grey water and faeces from the sewer to enter basements in this way.

A typical lifting unit is designed with a collecting tank housing a lifting device – usually a pump. For increased operating reliability some systems are also fitted with two pumps. Should one pump fail, continued operation is ensured. Grey water and waste water flow into the collecting tank via an inlet line. If the water level in this intermediate storage tank reaches a set level, the pump automatically starts up and lifts the water into the sewer system via a discharge line. When the waste water level in the collecting tank drops back down to the set level, the pump stops automatically.

Strengths and applications of KSB waste water lifting units

KSB’s waste water lifting units are powerful, flexible and versatile. Depending on the type series and design, the system can be installed in pits or at floor level.

Overview of waste water lifting unit applications:

  • Disposal of waste water in private, commercial, industrial and public sectors
  • Disposal of domestic waste water from washing machines, washbasins, sinks, showers or bathtubs
  • Disposal of waste water from toilets
  • Drainage of buildings and premises 
  • Overflow protection for rainwater harvesting systems or inlet tanks of fire-fighting systems
  • Automatic water disposal of rooms at risk of flooding (e.g. cellars, garages and basement flats)
