This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2017, and

39、conflicting national standards shall be withdrawn at the latest by October 2017.

The principal changes in this revision are as follows: a) the terminology has been aligned with EN 16323:2014; b) all the text relating to the determination of performance requirements and design criteria has been moved to Clause 5 as these are essentially part of th

42、evision of EN 13508-1 and some text that is duplicated in EN 13508-1 has been deleted; e) Clause 6 has been updated to align with EN 14654-2; f) contingency and emergency planning has been moved from the former Annex C to Clause 6 as it is part of the integrated sewer system planning process; g) som

43、e additional text from the former Annex D has been added to Clause 7, this has allowed the former Annex D to be deleted as it largely duplicated Clause 7; h) additional requirements have been added to Clause 8 on resilience of drain and sewer systems; i) all physical design requirements in the forme

44、r Clause 9 have been moved to a new Annex D; j) all the hydraulic design requirements in the former Clause 9 have been moved to prEN 16933-2 to provide a more coherent narrative; k) former Clause 11 (now Clause 10) has been updated to include requirements on dealing with major incidents; l) the text

45、 of the former Clause 12 has been integrated into 6.5.5, 10.4 (now 9.4) or 11.2 (now 10.2) as appropriate; m) the text from the former Annex A has been incorporated either in Clause 5 or Clause 7; n) a new Annex B on rehabilitation approaches has been added; BS EN 752:2017EN 752:2017 (E) 7 o) the te

BS EN 752:2017EN 752:2017 (E) 8 Introduction Drain and sewer systems are part of the overall wastewater system that provides a service to the community. This can be briefly

49、 described as: removal of wastewater from premises for public health and hygienic reasons; prevention of flooding in urbanized areas; protection of the environment. The overall wastewater system has four successive functions: collection; transport; treatment; discharge. Wastewater can, if necessary after treatment, be discharged to the environment or reused. Collection and transport of wastewater is provided by drain and sewer systems. Drain and sewer systems were installed because there was a need to remove the polluted water to
