This part covers the management and control o

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. Drains and sewers
26、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.

35、nes the process for preparation and implementation of an integrated drain and sewer system management plan which includes, at a strategic level, a plan for rehabilitation of the drain and sewer system. The amount of detail in the rehabilitation plan in the integrated drain and sewer system plan can
36、vary. This 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. BS EN 14654-2:2013EN 14654-2:2013 (E) 7 Figure 1 The integrated se
37、wer system management process (based on EN 752:2008, Figure 5) The integrated sewer system management process is applied successively to develop a rehabilitation programme based on the integrated sewer system management plan. The programme outlines a series of discrete rehabilitation projects to imp
38、lement the rehabilitation proposals in the plan. Following this, the integrated sewer system management process is then used to produce a detailed specification for each of these projects in the programme. Finally, following the implementation of each project, the rehabilitation programme and the in
39、tegrated sewer system management plan are reviewed and updated where necessary. The performance requirements for the rehabilitated systems should 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 proce
40、ss is summarised in Figure 2. BS EN 14654-2:2013EN 14654-2:2013 (E) 8 Figure 2 Summary of the rehabilitation management and control process BS EN 14654-2:2013EN 14654-2:2013 (E) 9 5 Rehabilitation plan An Integrated Sewer System Management Plan prepared in accordance with EN 752:2008, Clause 6, incl
41、udes: new development plan; rehabilitation plan; operational plan; maintenance plan. A rehabilitation 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
42、 possible if works are required urgently (e.g. in response to a drain or sewer failure). It is not necessary 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 reha
43、bilitation 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 preparation of the rehabilitation programme is the rehabilitation plan produced in accordance with EN 75
44、2:2008, Clause 6, and the performance requirements produced in accordance with EN 752:2008, Clause 5. The rehabilitation plan does not generally contain the necessary detail to proceed directly to the production of the project specification. The rehabilitation programme defines a series of projects,
45、 in line with the rehabilitation plan, to ensure that the drain and sewer system meets the performance requirements. The rehabilitation programme should define the objectives for each project in sufficient detail so that a project specification can then be produced in accordance with Clause 7. The p
46、reparation of the rehabilitation programme involves: a) review of the rehabilitation plan (see 6.2) to ensure it is still current and to establish what further investigation is required to develop the programme; b) further investigation (see 6.3) to provide the information necessary for the more det
47、ailed assessment; c) more detailed assessment (see 6.4) to identify further detail of the performance deficiencies that the programme needs to address; d) preparation of the programme (see 6.5) setting the scope and objectives for each of the projects. All stages of the preparation of the rehabilita
48、tion programme shall take account of the health and safety principles set out in EN 752:2008, Clause 7. 6.2 Review of the rehabilitation plan A review should be undertaken of the rehabilitation aspects of the integrated sewer system management plan. BS EN 14654-2:2013EN 14654-2:2013 (E) 10 This shou
49、ld include: a) ensuring the performance requirements used in the preparation of the integrated sewer system management plan are still current; b) checking that any assumptions regarding projected timescales included in the plan for new developments or other changes to the sewer system are still valid; c) identifying where further investigation and assessment is required in order to develo
