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.
