A backwater chamber in front of the building offers significant advantages. It enables all drainage points that are at risk of backwater to be safeguarded outside the building at a single central and maintenance-friendly point. Noise nuisance, for example due to pumps or similar, can be ruled out and there is no loss of living space in the building.
The Ø 1,000 mm standard backwater chamber in a monolithic design is made from robust and durable PE polymer. It is waterproof, resistant to aggressive wastewater and can be retrofitted with various backwater protection systems and pumps.
The Ø 1,000 mm backwater chamber is available in heights ranging from 1,180 mm to 3,180 mm and with a nominal drain size of DN 150 or DN 200 (Ø 160 or Ø 200mm).
The backwater chamber can be used simultaneously for building, roof and yard drainage with two lateral inlets.
The standard backwater chamber can be used as centralised protection for a separator system, for example, and offers additional connection options via the side inlets.
Application possibilities
This allows valuable living space to be gained in the house: The standard backwater chamber is installed in the ground outside the building. The installation depth can be varied. The following example illustrates what this looks like in a specific installation situation:
