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. Oth

26、er parts, dealing with other activities, may be added 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 building

27、s”. According to the CEN-CENELEC Internal Regulations, 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,

DIN EN 14654-1:2014-08 EN 14654-1:2014 (E) 5 Introduction This European Standard de

29、als with the management and control of cleaning operations 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

30、 performance requirements for the drain and sewer system (see 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 re

31、sults. Before commencing cleaning operations, the employing 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

32、is sometimes necessary to carry out some work in order to obtain 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 sewe

33、r systems. DIN EN 14654-1:2014-08 EN 14654-1:2014 (E) 6 1 Scope 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 progra

34、mmes, and the selection of techniques. This European Standard covers 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 wher

35、e it is discharged into a treatment works or receiving water body. 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 docume

36、nt and are indispensable for its application. For dated references, only the edition cited applies.

47、an which includes, at a strategic level, plans for the rehabilitation and 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.

48、Cleaning activities in drains and sewers can be carried out pro-actively, 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

49、 can be identified through a rehabilitation plan, a maintenance plan involving 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 implementing the cleaning activities in the integrated drain and sewer system management plan. The process is based on a staged application of the process outlined
