Substances hazardous to water; application for recognition of an expert organisation

Organisations may be recognised as expert organisations for the inspection of installations for the handling of substances hazardous to water if they fulfil the requirements of § 52 of the Ordinance on Installations for the Handling of Substances Hazardous to Water.


Expert organisations are recognised in accordance with the "Ordinance on Installations for Handling Substances Hazardous to Water" (AwSV). In Bavaria, the Bavarian State Office for the Environment (LfU) is responsible for the recognition and supervision of the expert organisations. The expert organisations are responsible for the training, examination, appointment and supervision of AwSV experts. For further details see § 52 AwSV.

Recognition procedure

The application for recognition as an expert organisation can be submitted in writing to the recognition authority. The application must be accompanied by the documents listed below.

Since the recognition is valid for all countries, only one recognition per organisation is required. The application for recognition should be submitted in the country in which the organization has its headquarters. When submitting the application, the organization must state whether it has also submitted an application for recognition as an expert organization in another country. Organisations based in Bavaria must apply for recognition in Bavaria.

Recognitions of other countries
Recognitions of other countries of the Federal Republic of Germany are also valid in Bavaria. The same applies to equivalent recognitions from member states of the European Union.


Pursuant to Section 53 Paragraph 1 Sentence 1 AwSV, the expert organisation may only appoint as experts persons who

  1. have the necessary reliability for the activity as an expert,
  2. are independent with regard to the inspection activity; in particular, there must be no connection between the tasks pursuant to § 52 Para. 1 Sentence 2 No. 1 and other services that are or were performed in connection with the planning or manufacture, sale, operation or maintenance of the systems or system components to be inspected
  3. are physically capable of carrying out the tests properly
  4. are able to guarantee, on the basis of their technical knowledge and experience gained through practical work, that they will carry out the tests properly,
  5. have the necessary knowledge of the relevant regulations of water, construction, operational safety, immission control and waste legislation and of the technical rules and regulations, and
  6. have not been appointed by any other expert organisation operating within the territory of the Federal Republic of Germany.

The expert knowledge required in accordance with section 53 subsection (1) sentence 1 number 4 shall be deemed to exist if

  • the authorized inspector has successfully completed a course of study in engineering or natural sciences in a field relevant to the activity performed or has vocational training recognized as equivalent.
  • The experience pursuant to subsection (1) sentence 1 number 4 requires at least five years of professional activity in the field of planning, construction or operation as well as the inspection of installations for handling substances hazardous to water.

Prior to appointment, the expert organisation shall satisfy itself by means of a theoretical and practical examination that the expert to be appointed meets the requirements pursuant to subsection (1) sentence 1 number 4. The result of this examination shall be documented.

In accordance with section 53 subsection (3) sentence 1 No. 3 AwSV, the expert organisation must have a sufficient number of experts at its disposal. As a rule, expert organisations are recognised which have at least five persons suitable for the inspection.


Pursuant to Article 52(6) AwSV, a decision on an application for recognition must be taken within a period of four months after submission of the complete documentation. The recognition may be subject to a reservation of revocation, a time limit, conditions, requirements and the reservation of conditions. If the expert organisation meets the requirements of the AwSV and the LAWA leaflet "Recognition of expert organisations and quality and monitoring associations", recognition is generally granted for five years.
