Sewage lift stations
Sewage lift stations are used to pump sewage from below the backwater level upwards so it can be drained via the public sewer system. Sewage lift stations usually have cutting devices for reducing the size of solid particles prior to the pumping operation.
In this work area, DIBt grants:
- national technical approvals (abZ) for sewage lift stations that are not covered by a harmonised standard or a European Technical Assessment;
- general construction technique permits (aBG) for the design and execution of the corresponding applications.
European Technical Assessments (ETAs) can also be issued for sewage lift stations which are not (fully) covered by a harmonised European standard.
The following technical rules for sewage lift stations (called wastewater lifting plants in the standards) have been referenced in the Official Journal of the European Union:
- EN 12050-1:2001 – Wastewater lifting plants for buildings and sites – Principles of construction and testing
- EN 12050-2:2000 – Wastewater lifting plants for buildings and sites – Principles of construction and testing – Part 2: Lifting plants for faecal-free wastewater
- EN 12050-3:2000 – Wastewater lifting plants for buildings and sites – Principles of construction and testing – Part 3: Lifting plants for limited applications
- EN 12050-4:2000 – Wastewater lifting plants for buildings and sites – Principles of construction and testing – Part 4: Non-return valves for faecal-free wastewater and wastewater containing faecal matter
The technical rules to be observed for the installation of drains inside or outside the building include:
- DIN EN 12050 (series) – Wastewater lifting plants for buildings and sites
- DIN EN 13564 (series) – Anti-flooding units for buildings
- DIN EN 12056 (series) – Gravity drainage systems inside buildings
- DIN 1986–100 – Drainage systems on private ground – Part 100: Specifications in relation to DIN EN 752 and DIN EN 12056
- DIN EN 476 – General requirements for components used in drains and sewers
- DIN EN 752 – Drain and sewer systems outside buildings
- DIN 4102-1 – Fire behaviour of building materials and building components – Part 1: Building materials; concepts, requirements and tests
- DIN EN 13501-1 – Fire classification of construction products and building elements – Part 1: Classification using data from reaction to fire tests

A national technical approval (abZ) and/or oder general construction technique permit (aBG) is granted upon application (see Model Building Code (MBO), Sections 16a(2) and18(2) and (4)). This also applies to amendments and supplements to, or renewals of existing approvals and/or construction technique permits.
No formal requirements apply. The following information is needed: name and address of the applicant, description of the product and/or construction technique and its field of use or application, type of decision required (new decision, amendment or supplement to, or renewal of, an existing decision).

European Technical Assessment (ETA)
To start the ETA procedure, please submit the form below. We will then check if the prerequisites for issuing an ETA are met, i.e., in particular, if the product is not fully covered by an existing harmonised standard. If the prerequisites are met, we will check whether a European Assessment Document (EAD) covering the requested assessment scope already exists or still needs to be developed. If an EAD needs to be developed or amended, a complete technical file needs to be established before the procedure can begin.Form for requesting a European Technical Assessment (ETA) (2 pages)
