Backflow Protection and Pumping Stations Mannheim
Why is backflow protection important?

Even with powerful sewer networks, heavy rainfall or blockages can cause backflow in the drainage pipes. Low-lying areas, such as basements or garden-level apartments, are particularly affected. Without proper protection, water can enter through floor drains, toilets, or washing machine connections. Professional backflow protection for wastewater ensures that your property remains protected in the long term.

The following video illustrates the consequences of heavy rainfall without backflow protection and explains which measures can be taken to prevent flooding and backflow.

What is Backflow?

The term describes a problem that occurs, for example, during heavy rainfall, when more wastewater enters the sewer system than it can handle. Wastewater then rises in the sewer network and escapes wherever it finds a way — from manhole covers, yard drains, basements, and in the worst case, even through toilets.

What is the Backflow Level?

The backflow level refers to the highest point to which the water level in a drainage system can rise. Drainage points located below this level must therefore be protected against backflow, if only for insurance reasons.

As a rule, the backflow level is considered to be the street surface (physical backflow level) plus a safety margin of 15 cm.

Herr Plaul war pünktlich. Hat uns auch alles sehr freundlich und geduldig erklärt. Er hat sehr engagiert gearbeitet und die Verstopfung in der Leitung gefunden. Die Rohre sind gereinigt, das Wasser läuft wieder einwandfrei ab. Sollten wir erneut Probleme haben, freuen wir uns, wenn Herr Plaul auch beim nächsten Mal wieder bei uns eingesetzt wird.

Questions and answers

Do you still have questions
about Backwater protection in Mannheim?

When is a pumping station required?

A pumping station is required when:

  • Wastewater containing fecal matter (e.g., from toilets) occurs below the backflow level,
  • There is insufficient slope to the sewer, or
  • The drainage system must function reliably even in the event of backflow.

(It is the safest method for backflow protection.)

Who is responsible for backflow protection?

The property owner is responsible for securing the drainage systems on their property — including basements and outbuildings.

What happens if there is no backflow protection?

Without proper backflow protection, damage can occur to the building, its contents, and the structure. Insurance companies may refuse claims if no standard-compliant backflow protection is in place, but the insurance policy requires it.

Which standards apply to backflow protection?

The most important standards are:

  • DIN EN 12056-4: Drainage systems inside buildings
  • DIN 1986-100: Drainage systems outside buildings

These standards define usage limits, technical requirements, and maintenance intervals.
