The purpose of backwater prevention systems is either to hinder wastewater from entering the drain pipe routing or to raise the drain pipe route to such an extent that backflowing wastewater cannot enter the building’s drainage system.

Why is backflow protection important?

Despite efficient sewer networks, heavy rainfall or blockages can lead to a back-up in the drainage pipe. Low-lying rooms such as cellars or basement apartments are particularly affected. Without suitable protection, there is a risk of water entering through floor drains, toilets or washing machine connections. Professional backflow protection for wastewater – ideally in combination with timely pipe renovation – ensures that your property remains permanently protected. The following video illustrates the consequences of heavy rainfall without backflow protection and explains and shows what measures can be taken to prevent flooding and backwater.

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 backwater 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.

How does a lifting station work?

For discharge points located below the backwater level – such as in basement rooms – a natural flow is not possible. In such cases, a lifting station transports the wastewater: the wastewater is collected in a tank and pumped into the gravity drain above the backwater level. Operation is automatic, controlled by a built-in float switch.

How does a backwater valve work?

Backwater valves are integrated into the pipe system and close automatically when water flows back from the sewer. There are mechanically operated versions as well as electrically controlled models with extended functions. Electrically operated systems are usually required in frequently used rooms.

What has to be considered during planning and installation?

There are a few points to consider:

Z

Composition of the wastewater (e.g. faecal-free / faecal-containing wastewater)

Z

Individual or collective protection of the drainage points

Z

Checking whether wastewater must be disposed during backwater

Z

Installation inside or outside buildings

Questions and answers

Do you still have questions
about Backwater protection in Darmstadt?

What are the advantages of a lifting system in Darmstadt?

A lifting unit is used to pump wastewater from lower parts of the building, such as rooms with basements, above the backwater level. In Darmstadt, 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 in Darmstadt?

Lifting systems in Darmstadt 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.
