Pertains to lifting plants for faecal-free wastewater for drainage of locations below flood level in buildings and sites to prevent any backflow of wastewater into the building.

This European Standard applies to lifting plants for faecal-free wastewater for drainage of locations below flood level in buildings and sites to prevent any backflow of wastewater into the building. These lifting plants may be prefabricated or delivered as prefabricated kits and assembled on site. This standard specifies general requirements, basic construction and testing principles, together with information on materials and assessment and verification of constancy of performance. Construction and testing requirements for non-return valves used in wastewater lifting plants are given in EN12050‑4 . This European Standard does not apply for pumping installations for drain and sewer systems outside buildings for pumping of municipal wastewater according to EN752:2008, AnnexF. This European Standard applies also to lifting plants for faecal-free wastewater which are not prefabricated but composed of individual components purchased from different suppliers and put together on site.
