BS EN 12050-1:2015EN 12050-1:2015 (E) 5 1 Scope This European Standard applies to lifting plants for wastewater containing faecal matter (referred to as “fa

30、ecal lifting plants” in this standard) 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 requi

31、rements, 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 EN 12050-4. This European Standard does n

32、ot apply for pumping installations for drain and sewer systems outside buildings for pumping of municipal wastewater according to EN 752:2008, Annex F. NOTE Lifting plants for wastewater containing faecal matter can also be used for wastewater that does not contain faecal matter and for surface wate

33、r. This European Standard applies also to lifting plants for wastewater containing faecal matter which are not prefabricated 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 nor
