Amendments This standard differs from DIN EN 752:2008-04 as follows: a) the terminology has been aligned with EN 16323:2014;
6、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 this policy activity and not the design process; c) Clause 5 has been updated to include references to show the links to the EU Water Framework Di
7、rective (2000/60/EC) together with its daughter directives and the EU Floods Directive (2007/60/EC); d) Clause 6 has been updated to align with the latest revision of EN 13508-1; 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) co
8、ntingency 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) 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
9、7; h) additional requirements have been added to Clause 8 on resilience of drain and sewer systems; i) all physical design requirements in the former 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
10、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 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 of the former Annex A has been in
11、corporated either in Clause 5 or Clause 7; n) Annex B “Rehabilitation approaches” has been added; o) the text of the former Annex C has been incorporated into Clause 6 (for planning activities), Clause 11 or the new Annex C; p) the former Annex F has been deleted as it is superseded by the prEN 1693

(DWA) (German Association for Water, Wastewater and Waste) is resp
14、onsible for issuing national provisions in the form of codes of practice and instruction sheets. The fields dealt with by the DWA Drainage Systems Committee (HA ES) include site drainage, drainage methods, planning, design, calculation (structural design, hydraulics), execution, operation, maintenan
15、ce and rehabilitation. The HA ES working groups deal with the following areas: generic subjects (geographical information systems, energy production from wastewater systems, flood protection of wastewater systems, material requirements in respect of drains and sewers, extraneous water, corrosion, fl
16、ow measurements); system requirements in respect of drain and sewer systems (hydraulics, pressure and vacuum sewerage, flow control, discharge and pollution load simulation); system requirements in respect of drain and sewer systems (infiltration of surface water, stormwater treatment, ground retent
17、ion filters, wastewater pumps); construction of drains and sewers (open and closed drains, structures within drain and sewer systems, location of trees, calculation of drains and sewers, drains and sewers in water protection areas, trench lining); operation and maintenance (sewer system operation an
18、d maintenance, data inventory, indirect discharge points, emissions from the sewage system); rehabilitation (condition survey, condition evaluation, rehabilitation planning, rehabilitation strategy). Integrated drainage planning The key element of integrated urban drainage management, described in D
19、IN EN 752 and in DWA-A 100 (ISiE) (Guidelines relating to integrated urban drainage) is integrated drainage planning. This is an interactive and permanent process with a holistic approach to drainage and water protection and deals not only with planning itself but also with the construction and oper
20、ation of systems. The area covered by urban drainage planning comprises the entire wastewater system and the affected watercourses. Figure NA.1 shows the area subject to urban drainage planning with its various system levels. The components, (partial) catchments areas, sewers and structures, form th
21、e drain or sewer system (system level III). The drain or sewer system and the wastewater treatment plant together form the (urban) wastewater system (system level II). Together with the watercourses affected by discharge (ground water system, surface watercourse), one or more wastewater systems form
22、 the urban drainage planning area (system level I). Where the water supply is also included, the entity is termed “urban water system” in Anglo-Saxon literature.
