EN 752:2008

Drain and sewer systems outside buildings

This European Standard sets out the objectives for drain and sewer systems outside buildings.  It specifies the functional requirements for achieving these objectives and the principles for strategic and policy activities relating to planning, design, installation, operation, maintenance and rehabilitation.
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 wastewater treatment plant or receiving water.
Drains and sewers below buildings are included provided that they do not form part of the drainage system for the building.

Entwässerungssysteme außerhalb von Gebäuden

Diese Europäische Norm legt Ziele für Entwässerungssysteme außerhalb von Gebäuden fest. Sie legt Funktionsanforderungen zum Erreichen dieser Ziele fest sowie Grundsätze für Strategie und Vorgehensweise in Bezug auf Planung, Bemessung, Bau, Betrieb, Unterhalt und Sanierung.
Sie gilt für Entwässerungssysteme, welche hauptsächlich als Freispiegelsysteme betrieben werden, von dem Punkt an, wo das Abwasser das Gebäude bzw. die Dachentwässerung verlässt oder in einen Straßenablauf fließt, bis zu dem Punkt, wo das Abwasser in eine Kläranlage oder einen Vorfluter 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

La présente Norme européenne définit les objectifs des réseaux d’évacuation et d’assainissement à l’extérieur des bâtiments. Elle spécifie les prescriptions de fonctionnement permettant d’atteindre ces objectifs ainsi que les principes des activités stratégiques et politiques liées à la planification, à la conception, à l’installation, au fonctionnement, à l’entretien et à la réhabilitation.
Elle s’applique aux réseaux d’évacuation et d’assainissement, principalement les réseaux gravitaires, 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 collecteurs situés sous des bâtiments sont inclus, à condition qu’ils ne fassent pas partie du réseau d’évacuation du bâtiment.
