Drain and sewer systems outside buildings - Management and control of activities - Part 1: General requirements
This document establishes requirements for the management and control of activities in drain and sewer systems outside buildings and specifies requirements for development and implementation of work programmes, and the selection of techniques.
This document covers general requirements for the management and control of activities.
It is applicable to drain and sewer systems from the point where wastewater leaves a building, roof drainage system, or paved area, to the point where it is discharged into a wastewater treatment plant 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.
Entwässerungssysteme außerhalb von Gebäuden - Management und Überwachung von Maßnahmen - Teil 1: Allgemeine Anforderungen
Dieses Dokument legt Anforderungen an das Management und an die Überwachung von Maßnahmen in Entwässerungssystemen außerhalb von Gebäuden sowie Anforderungen an die Entwicklung und Umsetzung der Arbeitsprogramme und die Auswahl von Verfahren fest.
Dieses Dokument umfasst allgemeine Anforderungen an das Management und die Überwachung von Maßnahmen.
Es gilt für Entwässerungssysteme ab der Stelle, an der das Abwasser ein Gebäude, eine Dachentwässerung oder eine befestigte Fläche verlässt, bis zu dem Punkt, an dem das Abwasser in eine Kläranlage oder in ein aufnehmendes Gewässer eingeleitet wird.
Abwasserleitungen und -kanäle unterhalb von Gebäuden sind hierbei eingeschlossen, solange sie nicht Bestandteil der Gebäudeentwässerung sind.

Introduction
Drain and sewer systems are part of the overall wastewater system that provides a service to the
community. This can be briefly described as:
— removal of wastewater from premises for public health and hygienic reasons;
— prevention of flooding in urbanized areas;
— protection of the environment.
The overall wastewater system has four successive functions:
— collection;
— transport;
— treatment;
— discharge.
Wastewater can, if necessary after treatment, be discharged to the environment or reused.
Collection and transport of wastewater is provided by drain and sewer systems.
Drain and sewer systems were installed because there was a need to remove the polluted water to
prevent diseases.
Traditionally, drain and sewer systems were constructed to collect and transport all types of
wastewater together irrespective of the initial source. This led to difficulties in handling the peak flows
in times of heavy rainfall and to the introduction of combined sewer overflows, which discharged
polluted water to surface receiving water bodies.
It was later recognized that separate systems, where foul wastewater was kept separate from runoff
derived from surface water, would be an improvement over such combined systems.
Although many drain and sewer systems started out as combined systems there are strong arguments
for considering the separation of foul wastewater and surface water. The pollutant effects are not the
same and the separation of effluents allows for the different treatment for each element of wastewater,
providing more environmentally friendly solutions.
This concept is included in the approach of integrated sewer management.
This document provides a framework for the design, construction, maintenance, operation and
rehabilitation of drain and sewer systems outside buildings. This is illustrated in the upper part of the
diagram in Figure 1. This document is supported by more detailed standards for the investigation,
design, construction, organization and control of drain and sewer systems.
Investigation and assessment standards include:
— EN 13508 (all parts), Investigation and assessment of drain and sewer systems outside buildings.
Design and construction standards include:
— EN 16932 (all parts), Drain and sewer systems outside buildings — Pumping systems;
— EN 16933-2, Drain and sewer systems outside buildings — Design — Part 2: Hydraulic design;
— EN 1295 (all parts), Structural design of buried pipelines under various conditions of loading;
— EN 1610, Construction and testing of drains and sewers;
— EN 12889, Trenchless construction and testing of drains and sewers;

sewers.
Management and control standards include:
— EN 14654 (all parts), Management and control of activities in drain and sewer systems outside
buildings.
To support these detailed standards information comes from specifications produced by individual
organizations for their own use. Product standards should also take into account the functional
requirements in this document through EN 476, EN 13380 and EN 14457.

sewer systems outside buildings and specifies requirements for development and implementation of
work programmes, and the selection of techniques.

4 General
EN 752:2017, Clause 6, outlines the process for preparation and implementation of an integrated drain
and sewer system management plan which includes, at a strategic level, a plan for new developments,
the operation and maintenance, and rehabilitation of the drain and sewer system and for contingency
and emergency planning.
This document sets out a process for implementing the proposals in the integrated drain and sewer
system management plan. The process is based on a staged application of the process outlined in
Figure 2.
Figure 2 —The integrated sewer system management process (based on EN 752:2017, Figure 5)
The integrated sewer system management process is applied successively to develop programmes
based on the integrated sewer system management plan. The programme outlines a series of projects to
implement 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 programme and the integrated sewer system management plan are
reviewed and updated where necessary. The performance requirements for the rehabilitated systems
should be in accordance with EN 752:2017, 5.2. At each stage further investigation and assessment is
carried out in accordance with EN 13508-1.
NOTE In this document “project” refers both to discrete projects and continuous activities.
This staged process is summarized in Figure 3.
Figure 3 — Summary of the management and control process
5 Integrated Sewer System Management Planning
Prior to implementation of any activities or design of any works EN 752:2017 recommends that an
Integrated Sewer System Management Plan is prepared in accordance with EN 752:2017, Clause 6, for
the drain and sewer system to achieve the performance requirements in accordance with EN 752:2017,
Clause 5. However, this is not always possible if activities are required urgently (e.g. in response to a
drain or sewer failure).
The detailed plan does not include detailed descriptions of the solutions. It includes only general
descriptions of the approaches to be taken.
The aims of the programmes of activities should be based on the relevant detailed plans in the
integrated sewer system management plan.
6 Preparation of programme
6.1 Introduction
The plan does not generally contain the necessary detail to proceed directly to the production of the
project specification. The programme defines a series of projects, in line with the plan, to ensure that
the drain and sewer system meets the performance requirements. The 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 preparation of the programme involves:
a) review of the 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 detailed
assessment;
c) more detailed assessment (see 6.4) to identify further detail of the performance deficiencies that
the programme aims 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 programme shall take account of the health and safety principles set
out in EN 752:2017, Clause 7.
6.2 Review of the plan
A review should be undertaken of the relevant aspects of the integrated sewer system management
plan.
