Apply for discharge of waste water into public waste water treatment plants


For the discharge of wastewater (waste water) into a public wastewater plant (indirect discharge), a permit is usually required in Germany, insofar as the Wastewater Ordinance specifies requirements for the wastewater for the location of the seizure or before its mixing. The authorisation is granted by the competent authorities of each country.

For those industries and activities (such as .B chemical industry, paper production, metal processing, cooling water use) in which pollutants are to be expected in the wastewater that are not sufficiently purified in a municipal sewage treatment plant, the legislator has defined requirements in the industry-specific annexes to the Wastewater Ordinance.

In order to comply with these requirements, special measures and wastewater pretreatment plants are required to reduce the pollutant load in such a way that the wastewater can then be cleaned without damage in a public sewage treatment plant.

Would you like to discharge wastewater into a public sewage system (sewage system)? Then an application for approval must be submitted to the competent authority of the respective federal state.

  • Authority explains the approval procedure for indirect discharge
  • You submit the application documents.
  • Authority checks your application documents. If documents are missing, the authority will ask you to submit these documents later.
  • You submit the missing documents.
  • Authority examines subsequently submitted documents
  • Authority prepares the permit.
  • You will receive the approval notice for indirect initiation.
  • You pay the administration fee costs.

Contact your county's water authority or county-level city.

Authorisation may be granted (discretion) if:

  • the requirements applicable to the discharge in accordance with the Waste Water Ordinance in its current version, including the general requirements (general requirements, requirements for the place of the seizure and before mixing) are complied with.
  • the fulfilment of the requirements for direct discharge is not jeopardised, and
  • construct and operate waste water installations or other facilities necessary to ensure compliance with the requirements set out in points 1 and 2

The required documentation depends on the wastewater (industrial wastewater, commercial wastewater) to be discharged into the public sewage system.

An administrative fee must be paid to the respective federal state for the administrative performance of the permit. The administration fee is based on the respective state law provisions on the administrative fees.

The application must be submitted at an early stage, as wastewater may only be discharged into a public sewage plant with a permit.

The description and execution of the individual forms varies from one federal state to another. Generally formulated, there are application forms, checklists and information sheets as declarations or forms.
