Grease separators
Grease separators serve to separate grease from commercial wastewater.
Regulatory framework
Grease separators that are covered by harmonised standard EN 1825-1 must bear the CE marking.
Concerning the use of grease separators, please note the provisions of the federal states following MVV TB, Section B 4.2 'Technical requirements for installation, operation and maintenance of systems using construction products for wastewater treatment'.
For grease separators in accordance with EN 1825-1:2004, national technical approvals were granted until October 2016. As a result of the implementation of the judgement of the European Court of Justice of 16 October 2014 in case C-100/13, national technical approvals are no longer granted for these products if they bear the CE marking on the basis of the Construction Products Regulation (Regulation (EU) No 305/2011). The products may not be marked with the national conformity mark (further guidance is linked below (German)).
Grease separators that are not covered by the harmonised standard, such as grease separators for mobile rinsing systems, may fall under the Ordinance on the determination of the suitability of construction products and construction techniques under water law by means of verifications in accordance with the Building Codes of the federal states (WasBauPVO).
Cf. WasBauPVO, Section 1(1)(c) 'Grease separators'.
DIBt grants national technical approvals (abZ) in combination with general construction technique permits (aBG) for the latter. The abZ/aBG serve to verify the suitability of the systems both from a construction and water legislation point of view.
The following approval principles are currently available:

The approval principles covering this work area are not published, but are made available to the applicants during the procedure.

To prepare an abZ/aBG for your construction product, we need an application from you. We recommend that you contact us prior to doing so. Feel free to send us your enquiry informally via email to dibt(at)dibt(.)de or to the competent technical contact listed in the top right.
For a first assessment, please send us the following information:
- Description of the construction product and its intended field of use
- e.g. material, configuration, number of sizes, variants, dimensions
- e.g. use in walls, ceilings, interior construction, building services
- Description of the construction technique and its field of application
- e.g. design of walls, ceilings, elements, etc., and interaction of components
- e.g. application in foundation engineering, reinforced concrete construction, building insulation; as load-bearing or non-load-bearing component; under static and quasi-static loading; fire exposure; other environmental exposures
- Information regarding impact on regulatory concerns
- in particular structural integrity, fire protection, health and environment protection, sound insulation as well as thermal performance
- Explanation of need for an abZ/aBG
- Do you significantly deviate from the Technical Building Rules?
- Or do neither Technical Building Rules nor generally recognised technical rules exist?
- Contact details
- preferably email address and/or telephone number, as well as name, organisation/company, and postal address
We will then contact you to clarify the next steps.
If you already hold a DIBt approval and/or construction technique permit and wish to apply for an amendment, supplement, or renewal, please use the form provided below.
