35、) 5 1 Scope 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 assembl

36、ed 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 g

37、iven in EN 12050-4. This European Standard does not apply for pumping installations for drain and sewer systems outside buildings for pumping of municipal wastewater according to EN 752:2008, Annex F. This European Standard applies also to lifting plants for faecal-free wastewater which are not pref

38、abricated but composed of individual components purchased from different suppliers and put together on site. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
