Your Waste Water Connection Is only a few Steps Away

Our check list will help you with the application procedure for a waste water connection.

Our tip: Apply for your waste water connection in due time before construction begins and plan in a processing time of up to six weeks.

If you require supply line information before making an application, you can request it from us or via the online supply line portal infrest.de. The supply line information offers customers planning a construction project important information about where the supply pipelines are located.
