This European Standard applies to lifting plants for wastewater containing faecal matter (referred to as "faecal lifting plants" in this Standard), which can also be used for wastewater that does not contain faecal matter, for drainage of locations below flood level in buildings and sites outside buildings to prevent any backflow of wastewater into the building. This document contains general requirements, basic construction and testing principles, together with information on materials and conformity evaluation. NOTE 1 Construction and testing requirements for non-return valves used in faecal lifting plants are given in EN 12050-4. NOTE 2 For pumping installations for drain and sewer systems outside buildings which are used for pumping of municipal waste water, see EN 752:2008, Annex F.
