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of an identical text or by endorsement, at the latest by July 2013, and conflicting national standards shall be withdrawn at the latest by July 2013. Atte
22、ntion 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 all such patent rights. The standard series EN 14654 contains the following parts: EN 14654-1, Management and cont

28、nt and implementation of work programmes, and the selection of techniques. This part covers the management and control of rehabilitation activities. It is applicable to drain and sewer systems, which operate essentially under gravity, from the point where wastewater leaves a building, roof drainage
29、system, or paved area, to the point where it is discharged into a treatment works or receiving water. 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 no

The amount of detail in the rehabilitation plan in the integrated drain and sewer system plan can vary. This
40、 European Standard sets out a process for implementing the rehabilitation proposals in the integrated drain and sewer system management plan. The process is based on a staged application of the process outlined in Figure 1. Copyright European Committee for Standardization Provided by IHS under licen

42、elop a rehabilitation programme based on the integrated sewer system management plan. The programme outlines a series of discrete rehabilitation projects to implement the rehabilitation proposals in the plan. Following this, the integrated sewer system management process is then used to produce a de
43、tailed specification for each of these projects in the programme. Finally, following the implementation of each project, the rehabilitation programme and the integrated sewer system management plan are reviewed and updated where necessary. The performance requirements for the rehabilitated systems s
44、hould be in accordance 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 summarised in Figure 2.

A rehabilitatio
47、n plan, as part of an Integrated Sewer System Management Plan should be prepared for the drain and sewer system prior to design or construction of any rehabilitation works. However, this is not always possible if works are required urgently (e.g. in response to a drain or sewer failure). It is not n
48、ecessary for the rehabilitation plan to include detailed descriptions of the solutions. It may include only general descriptions of the approaches to be taken. A number of different approaches to rehabilitation options which may be used in preparing a rehabilitation plan are described in Annex A (normative). 6 Preparation of rehabilitation programme 6.1 Introduction The starting point for the prepa
