Backwater Protection and Wastewater Lifting Systems in Nidderau

Installation, maintenance and repair

Are you looking for services relating to backwater protection and sewage/wastewater lifting equipment in the Nidderau area? Abfluss-AS is here to assist you. The main purpose of backflow prevention systems is to prevent wastewater from entering the drainage pipe network by either blocking the sewage or raising the drainage pipe system sufficiently to ensure that backflowing sewage cannot enter the building’s drainage system. Our experienced team can assist you with the selection of the right system for your property, or with the maintenance and repair of the systems you have in place.

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)
