Detailed description

Facade cleaning involves removing dirt, paint or other deposits from the external surface of a building. This is usually done with the help of a high-pressure cleaner and sometimes also with chemicals.



When you clean a facade, the waste water that is produced is usually different from normal waste water. This can be the case, for example, because you

  • use special cleaning agents and the wastewater therefore contains different substances than usual.
  • use a high-pressure cleaner, which increases the amount of wastewater and removes problematic substances.

If you want to discharge wastewater into the public sewage system as part of the facade cleaning, you must report this to the responsible authority. This ensures that the wastewater discharge or waste disposal is carried out correctly.
