Drain and sewer systems outside buildings - Management and control of activities - Part 3: Drain and sewer cleaning
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 the management and control of drain and sewer cleaning.
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 3: Kanalreinigung
Dieses Dokument stellt die Anforderungen an das Management und an die Überwachung von Maßnahmen in Entwässerungssystemen außerhalb von Gebäuden auf und legt Anforderungen an die Entwicklung und Umsetzung der Arbeitsprogramme und die Auswahl von Verfahren fest.
Dieses Dokument behandelt das Management und die Überwachung der Reinigung der Abwasserleitungen und -kanäle.
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.
Réseaux d'évacuation et d'assainissement à l'extérieur des bâtiments - Gestion et contrôle des activités opérationnelles - Partie 3: Curage des branchements et des collecteurs
Le présent document établit les prescriptions de gestion et de contrôle des activités dans les réseaux d’évacuation et d’assainissement à l’extérieur des bâtiments, et spécifie les prescriptions concernant l’élaboration et la mise en oeuvre de programmes de travaux, ainsi que le choix des techniques employées.
Le présent document traite de la gestion et du contrôle du curage des branchements et des collecteurs.
Il s’applique aux réseaux d’évacuation et d’assainissement à partir du point où les eaux usées quittent un bâtiment, un système d’évacuation de toiture ou une surface revêtue, jusqu’au point où elles se déversent dans une station d’épuration ou un milieu récepteur aquatique.
Les branchements et les collecteurs d’assainissement situés sous les bâtiments sont également visés dès l’instant qu’ils ne font pas partie du système d’évacuation propre au bâtiment.
