18、word This document (EN 14654-1:2014) has been prepared by Technical Committee CEN/TC 165 “Waste water engineering”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the l

19、atest by December 2014, and conflicting national standards shall be withdrawn at the latest by December 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or

20、all such patent rights. This document supersedes EN 14654-1:2005. EN 14654 “Management and control of operational activities in drain and sewer systems outside buildings” contains the following parts: Part 1: Cleaning; Part 2: Rehabilitation. Other parts, dealing with other activities, may be added

21、later. In drafting this part of EN 14654, account has been taken of other available standards, in particular EN 752 “Drain and sewer systems outside buildings” and EN 13508 “Investigation and assessment of drain and sewer systems outside buildings”. According to the CEN-CENELEC Internal Regulations,

22、 the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, La

BS EN 14654-1:2014EN 14654-1:2014 (E) 5 Introduction This European Standard deals with the management and control of cleaning operations

24、in drain and sewer systems. Cleaning operations are a part of the general management of drain and sewer systems. The employing authority sets the aims of the cleaning operations, expressed in terms of the end result, necessary to achieve the performance requirements for the drain and sewer system (s

25、ee EN 752), and develops a strategy to meet these aims. The employing authority also produces a specification for cleaning operations taking account of the aims and the strategy, and including indicators for controlling the quality of the results. Before commencing cleaning operations, the employing

26、 authority should have a thorough knowledge of the drain and sewer system and an assessment of the hydraulic conditions and other relevant factors in order to understand the type and frequency of cleaning necessary (see EN 752). However, it is sometimes necessary to carry out some work in order to o

27、btain this knowledge. On completion, a report of the cleaning operations is produced, providing information on the works, on any difficulties encountered and any anomalies. This information is used to improve the management of drain and sewer systems. BS EN 14654-1:2014EN 14654-1:2014 (E) 6 1 Scope

28、This European Standard establishes the general principles for the management and control of operational activities in drain and sewer systems outside buildings and specifies requirements for development and implementation of work programmes, and the selection of techniques. This European Standard co

29、vers the management and control of cleaning. It is applicable to drain and sewer systems, which operate essentially under gravity, from the point where wastewater leaves a building, roof drainage system, or paved area, to the point where it is discharged into a treatment works or receiving water bod

30、y. Drains and sewers below buildings are included provided that they do not form part of the drainage system of the building. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

42、maintenance of the drain and sewer system. The amount of detail in these plans in the integrated drain and sewer system plan can vary. A maintenance plan should include a cleaning plan where cleaning activities are necessary. Cleaning activities in drains and sewers can be carried out pro-actively,

43、to prevent problems occurring or to clean a drain or sewer before particular operations (e.g. an inspection or renovation work) or reactively in response to problems that have occurred. The requirements for pro-active cleaning can be identified through a rehabilitation plan, a maintenance plan invol

44、ving periodic monitoring or as part of an integrated sewer system management plan in accordance with EN 752. Consideration shall also be given to the feasibility of preventing deposition of sediments for example by rehabilitation of the sewer. This European Standard sets out a process for implementi

45、ng the cleaning activities in the integrated drain and sewer system management plan. The process is based on a staged application of the process outlined in Figure 1. NOTE Based on EN 752:2008, Figure 5. Figure 1 Integrated Sewer System Management Process BS EN 14654-1:2014EN 14654-1:2014 (E) 9 The

46、integrated sewer system management process is applied successively to develop a cleaning programme based on the integrated sewer system management plan. The programme outlines a series of discrete projects to implement the plan. Following this, the integrated sewer system management process is then

47、used to produce a detailed specification for each of these projects in the programme. Finally, following the implementation of each project, the cleaning programme and the integrated sewer system management plan are reviewed and updated where necessary. The performance requirements should be in acco

48、rdance with EN 752:2008, 5.2. At each stage further investigation and assessment is carried out in accordance with EN 13508-1. This staged process is summarized in full in Figure 2. The extent and detail of these stages should be determined by the characteristics of the individual systems. According

49、 to the specific local conditions, stages may be consolidated or, if they are not necessary, omitted.
