Backflow Protection and Pumping Station Services in Hanau
Urban drainage systems are increasingly being pushed to their limits by heavy rainfall and prolonged rain. This often leads to flooding and backwater, which poses a particular threat to basements and ground floors.
Backwater valves and lifting systems in Hanau can effectively prevent such problems. While backflow prevention devices use a backflow flap to close the sewage pipe from the outside, lifting systems use two safety mechanisms: the backflow loop, which prevents water from entering due to its position above the backflow level, and an additional backflow flap installed in the lifting system.
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?
As a rule, the backflow level is considered to be the street surface (physical backflow level) plus a safety margin of 15 cm.
What has to be considered during planning and installation?
Composition of the wastewater (e.g. faecal-free / faecal-containing wastewater)
Installation inside or outside buildings

Questions and answers
Do you still have questions
about Backwater protection in Hanau?
What are the advantages of a lifting system?
A lifting unit is used to pump wastewater from lower parts of the building, such as rooms with basements, above the backwater level. Where many buildings are older and possibly not designed for modern wastewater requirements, a lifting unit offers the advantage of ensuring the safe removal of wastewater and counteracting backwater problems.
How do I know if I need a backflow preventer?
Whether you need backflow protection depends on various factors, such as the location of your building and the height of the sewer system compared to your basement or other lower-lying rooms. It is advisable to seek advice from a specialist company to determine whether backflow protection is necessary in your structural situation.
What maintenance measures are required for lifting systems?
Lifting systems require regular maintenance to ensure their functionality. This includes checking pumps, cleaning backwater valves and testing the entire system. Regular maintenance helps to prevent breakdowns and extend the service life of the system.
