From installation to maintenance and repair, we’re at your service. Backflow prevention solutions aim to prevent sewage from entering the drainage channels or raise these channels sufficiently to prevent any backflow from compromising your building’s drainage system.

What is backwater?

The term describes a situation that occurs when more wastewater is temporarily entering into the sewer system than it can “swallow”, e.g. due to heavy rainfall. The wastewater then rises within the sewer system and inexorably escapes wherever it can – i.e. from manhole covers, yard drains, in your cellar and, in the worst case, in your toilet.

What is the backflow level?

The backwater level is the highest level to which the water level in a drainage system can rise. Drainage points that lie below this level must be secured against backwater.

In general, the backwater level is the upper edge of the street (physical backwater level) plus a 15 cm safety distance.


What has to be considered during planning and installation?

There are a few points to consider:

  • Composition of the wastewater (e.g. faecal-free / faecal-containing wastewater)
  • Installation inside or outside buildings
  • Individual or collective protection of the drainage points
  • The slope to the street sewer
  • Checking whether wastewater must be disposed during backwater
  • Legal standards (e.g. DIN EN 13564 or DIN EN 12050)
