Together with EN 16932-1:2018 and EN 16932-3:2018, this document supersedes EN 1091:1996 and
EN 1671:1997.
EN 16932, Drain and sewer systems outside buildings — Pumping systems, contains the following parts:
— Part 1: General requirements;
— Part 2: Positive pressure systems;
— Part 3: Vacuum systems.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,

1 Scope
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 positive pressure systems.
