Drain and sewer systems outside buildings - Pumping systems - Part 3: Vacuum systems

This European Standard specifies requirements for design, construction and acceptance testing of wastewater pumping systems in drain and sewer systems outside the buildings they are intended to serve. It includes pumping systems in drain and sewer systems that operate essentially under gravity as well as systems using either positive pressure or partial vacuum.
This document is applicable to vacuum drain and sewer systems.

Entwässerungssysteme außerhalb von Gebäuden - Pumpsysteme - Teil 3: Unterdruckentwässerungssysteme

Pumpsystemen in Entwässerungssystemen außerhalb von Gebäuden, zu deren Entwässerung sie dienen, fest. Sie betrifft sowohl Pumpsysteme in Entwässerungssystemen, welche hauptsächlich als Freispiegelsysteme betrieben werden, als auch Systeme, die entweder mit Überdruck oder Unterdruck betrieben werden.
Dieses Dokument gilt für Unterdrucksysteme.

Réseaux d'évacuation et d'assainissement à l'extérieur des bâtiments - Systèmes de pompage - Partie 3: Systèmes sous vide

La présente norme européenne fournit des prescriptions pour la conception, la construction et les essais d’acceptation des systèmes de pompage des eaux usées dans les réseaux d’évacuation et d’assainissement à l’extérieur des bâtiments qu’ils sont destinés à desservir. Elle couvre les installations de systèmes de pompage dans les réseaux d’évacuation et d’assainissement, principalement les réseaux gravitaires, ainsi que les réseaux utilisant soit une pression positive, soit un vide partiel.
Le présent document s’applique aux réseaux d’évacuation et d’assainissement sous vide.

Sistemi za odvod odpadne vode in kanalizacijo zunaj stavb - Črpalni sistemi - 3. del: Vakuumski sistemi

Ta evropski standard določa zahteve za projektiranje, izdelavo in preskušanje sprejemljivosti črpalnih sistemov odpadnih vod v sistemih za odvod in kanalizacijo zunaj stavb, v katerih so namenjeni za delovanje. Vključuje inštalacije črpalnih sistemov v sistemih za odvod in kanalizacijo, ki delujejo zlasti s pomočjo gravitacije, kot tudi v sistemih, ki uporabljajo pozitivni tlak ali delni vakuum.
Ta dokument se uporablja za sisteme za vakuumski odvod in kanalizacijo.
