CEN/TC 165/WG 21 - Drainage systems inside buildings

This European Standard applies to non-return valves used for faecal-free wastewater and wastewater containing faecal matter lifting plants. This Standard specifies general requirements, basic construction and testing principles together with information on materials and the relevant assessment and verification of constancy of performance.

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 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 prefabricated but composed of individual components purchased from different suppliers and put together on site.

This European Standard applies to lifting plants for wastewater containing faecal matter (referred to as “faecal 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 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 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.
NOTE    Lifting plants for wastewater containing faecal matter can also be used for wastewater that does not contain faecal matter and for surface water.
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.

This European Standard applies to lifting plants for limited applications for domestic non-commercial wastewater containing or not containing faecal matter and located below flood level.
NOTE   Limited application means that the number of users is small and the plant is located in the same room as the sanitary appliance(s) served by it ) which are installed in accordance with EN 12056–1 and the layout and calculation are in accordance with EN 12056–4.
This European Standard applies to lifting plants for limited applications designed for wastewater containing faecal matter, where there is another WC available above flood level, and the plants serve no more than a single WC to which it is directly connected (at a distance of max. 0,5 m) and one hand washbasin, one shower and one bidet provided no other sanitary appliance is directly or indirectly connected.
This European Standard also applies to lifting plants for limited applications designed for faecal free wastewater, where a maximum of one hand washbasin or kitchen sink plus one further appliance such as a bathtub or a washing machine or a shower or a dish washer or an urinal are connected. No other sanitary appliance shall be directly or indirectly connected.
This European Standard contains general requirements, basic construction and testing principles, together with information on materials.
Construction and testing requirements for non-return valves used in wastewater lifting plants for limited applications are given in EN 12050 4.
This European Standard does not apply for lifting plants for limited applications for wastewater containing faecal matter where WC flushing is carried out by pressure flush valve.

This European Standard applies to waste water drainage systems which operate under gravity. It is applicable for drainage systems inside dwellings, commercial, institutional and industrial buildings. The field of application of this European Standard is shown in Figure 1. Differences in plumbing within Europe have led to a variety of systems being developed. Some of the major systems in use are described but this Standard has not attempted to detail the intricacies of each system. Detailed information additional to that contained in this Standard may be obtained by referring to the technical documents listed in Annex A .

This European Standard applies to wastewater drainage systems, which operate under gravity. It is applicable for drainage systems inside dwellings and commercial, institutional and industrial buildings. This third part of this European Standard describes a method of calculating the hydraulic adequacy of non-siphonic roof drainage systems and gives performance requirements for siphonic roof drainage systems. It also sets standards for the layout and installation of roof drainage insofar as they affect flow capacity.

This part gives layout, operation and maintenance requirements for lifting plants for wastewater containing faecal matter, faecal-free wastewater and rainwater within buildings and sites, together with their discharge pipework and connection to drain. It also covers faecal wastewater lifting plants for limited applications.

This European Standard specifies system requirements (performance) and the principal requirements for design and installation with related verification and test methods for vacuum drainage systems inside buildings transporting domestic wastewater from dwellings and commercial properties but excluding stormwater and rainwater.

This part of this European Standard applies to lifting plants for wastewater containing faecal matter (referred to as "faecal lifting plants" in this Standard), which may also be used to deal with wastewater that does not contain faecal matter, for drainage of locations in buildings and sites below flood level for buildings and sites to prevent any backflow of wastewater into the building. This part of the European Standard contains general requirements, basic construction and testing principles, together with advice on materials and quality surveillance.

This part of this European Standard applies to non-return valves used in conjunction with faecal and faecal-free wastewater lifting plants. This part of the standard contains general requirements, basic construction and testing principles together with information on materials and quality surveillance.
