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 200 mm).
Features & benefits
- Installation outside the building preserves interior living space
- Variable installation depth capability
- Retrofittable with backwater valves and pumping systems
- Monolithic design ensures permanent leak-proofing
- Root-resistant construction
- Impact-resistant, unbreakable material
Applications
- Simultaneous handling of building, roof, and yard drainage via two lateral inlets
- Centralized backwater protection for separator systems with additional connection options
