Management and control of cleaning operations in drains and sewers - Part 1: Sewer cleaning

This European Standard specifies the general principles for the management and control of cleaning operations in drain and sewer systems and specifies requirements for implementation of cleaning programmes and for working practices.
It is applicable to drain and sewers systems outside buildings, which operate essentially under gravity, from the point where the sewage leaves a building or roof drainage system, or enters a road gully, 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.

Management und Überwachung von Reinigungsmaßnahmen in Abwasserkanälen und -leitungen - Teil 1: Reinigung von Kanälen

Diese Europäische Norm stellt die allgemeinen Verfahren zu Management und Überwachung von Reinigungs-maßnahmen
in Entwässerungssystemen auf und legt Anforderungen an die Umsetzung des Reinigungsprogramms
und die Arbeitsverfahren fest.
Sie gilt für Entwässerungssysteme außerhalb von Gebäuden, welche hauptsächlich als Freispiegelleitungen
betrieben werden. Sie gilt von dem Punkt an, wo das Abwasser das Gebäude bzw. die Dachentwässerung verlässt
oder in einen Straßeneinlauf fließt, bis zu dem Punkt, wo das Abwasser in eine Behandlungsanlage oder in einen
Vorfluter eingeleitet wird. Abwasserleitungen und -kanäle unterhalb von Gebäuden sind hierbei eingeschlossen,
solange sie nicht Bestandteil der Gebäudeentwässerung sind.

Gestion et contrôle des opérations de nettoyage des canalisations d'évacuation et d'assainissement - Partie 1: Nettoyage des canalisations

La présente Norme européenne établit les principes généraux de gestion et de contrôle des opérations de
nettoyage des réseaux d�évacuation et d�assainissement, et prescrit les exigences relatives à la mise en
application de programmes de nettoyage et de pratiques de travail.
Elle est applicable aux réseaux d'évacuation et d'assainissement extérieurs aux bâtiments, qui fonctionnent
principalement à écoulement libre, depuis le point où l'effluent quitte le bâtiment ou le système d'évacuation
de la toiture, ou atteint un caniveau de chaussée, jusqu'au point où il est déversé dans une station d'épuration
ou le milieu récepteur. Les canalisations d�évacuation et d�assainissement situées sous les bâtiments sont
également visées dès l'instant qu'elles ne font pas partie du système d'évacuation propre au bâtiment.

Introduction
This European Standard deals 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 owner 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 (see EN 752-2) and develops a strategy to meet these
aims. The owner 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 owner 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 752-7). However it 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 sewer systems.
