If you want to discharge precipitation water locally without causing damage, you must notify the responsible authority.

You do not need a permit under water law to discharge precipitation water close to the site without causing damage. You only need to notify the authorities in good time before you start.

Rainwater is water that runs off from built-up or paved areas.

Surface waters are rivers, lakes, canals, streams, ditches and ponds.

As a rule, the discharge is harmless if the precipitation water runs off areas with low levels of pollution and is not discharged into protected areas or waters in very good condition.
