Cleaning facades or buildings
What is it?
Buildings, bridges or overpasses occasionally need their exteriors cleaned. This can cause environmental pollution. For example, if you let the waste water run off into the soil or sewers. Others may also be inconvenienced by the noise of the cleaning equipment. Or from the dust released. This is why you must report the work.
Are you working near open water, such as a ditch? Wastewater should not get into that. If you cannot prevent this, you may need a water permit. You can do the online check if you are not sure.
You do not need to report cleaning work that recurs frequently. For example, window cleaning.
