Proof of flooding
Creation of flooding evidence for Leipzig
A “drainage system should be such that a sufficient protection against unplanned flooding given is”.
Unscheduled flooding is defined, for example with the leakage of water inside buildings or the flooding of areas on which substances hazardous to water or other protected goods are stored.
On the other hand, there is the controlled flooding of the property without damage.
In a flood evidence, it must be mathematically proven that there is protection against flooding of the property or that there is a controlled, damage-free flooding.
Proof of flooding is required for properties:
- with an area greater than 800 m²
- and a drainage area with a sewer connection.
The proof is intended to ensure that a property is flooded without consequences.
To do this, the amount of precipitation to be retained is determined.
This amount of precipitation is required for the planning and construction of rain retention systems.
The follow l ose flooding of land must for example by walls, wells, trenches or dykes be ensured.
If people, animals or property have to be protected, more effective rain retention areas such as retention basins, storage ducts, etc. must be built.
We will help you to draw up a flood certificate.

Proof of infiltration
Creation of proof of infiltration for Leipzig
Anyone wishing to allow rainwater to seep into the ground and / or the groundwater generally requires evidence of seepage under water law.
Proof of infiltration is required for the planning and construction of an infiltration system.
Owners of commercial areas are legally obliged to apply for a permit for rainwater infiltration.
If your property is located in a water protection area, you are also obliged to submit proof of infiltration for the operation of a rainwater infiltration system.
This proof / permit eliminates the sometimes high rainwater charges. This helps business and saves costs.
But it is primarily about maintaining and increasing the groundwater level. If rainwater is uselessly drained into the sewer system, it will be lost to us and nature.
The groundwater level is therefore constantly falling.
The result is that green landscapes and biotopes suffer from massive drought and disappear.
