Construction products detail

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.

Regulatory framework

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
