BS EN 16932-1:2018EN 16932-1:2018 (E) 5 Introduction Drain and sew

29、er systems are part of the overall wastewater system that provides a service to the community. This can be briefly described as: removal of wastewater from premises for public health and hygienic reasons; prevention of flooding in urbanised areas; protection of the environment. The overall wastewate

30、r system has four successive functions: collection; transport; treatment; discharge. Collection and transport of wastewater is provided by drain and sewer systems. EN 752 provides a framework for the design, construction, maintenance, operation and rehabilitation of drain and sewer systems outside b

31、uildings. This is illustrated in the upper part of the diagram in Figure 1. EN 752 is supported by more detailed standards for the investigation, design, construction, organization and control of drain and sewer systems. Investigation and assessment standards include: EN 13508 (all parts), Investiga

32、tion and assessment of drain and sewer systems outside buildings. Design and construction standards include: EN 16932 (all parts), Drain and sewer systems outside buildings Pumping systems; EN 16933-2, Drain and sewer systems outside buildings Design Part 2: Hydraulic design; EN 1295-1, Structural d

To support these detailed standards information can come from specifications produced by individual organisations fo

35、r their own use. Product standards take also into account the functional requirements in EN 752 through EN 476, EN 13380 and EN 14457.
