Overview

EN 12109:1999 (published by CEN) defines the requirements for vacuum drainage systems inside buildings. The standard covers system performance requirements and the principal requirements for design and installation, together with related verification and test methods. It applies to vacuum systems that transport domestic wastewater from dwellings and commercial properties and explicitly excludes stormwater and rainwater.

Key Topics

The standard addresses the following core technical topics and requirements:

• System performance: functional and operational performance criteria that a vacuum drainage installation must meet.
• Design principles: guidance on planning system layout and capacity to ensure reliable wastewater conveyance.
• Installation requirements: recommended practices and constraints for correct assembly and integration in buildings.
• Verification and test methods: procedures to confirm system integrity, performance and compliance after installation.
• Scope limitations: clear exclusion of stormwater and rainwater applications to avoid misuse of the standard.
• Component considerations: requirements that typically cover control equipment, piping, valves and collection points as part of the overall system performance (described at a system level rather than prescribing specific products).

Applications

EN 12109 is practical for professionals and projects involving vacuum wastewater systems in buildings, including:

• Building services engineers and plumbing designers specifying vacuum drainage solutions.
• Installers and contractors performing system installation, commissioning and on-site testing.
• Manufacturers and suppliers documenting product performance and compatibility with European system requirements.
• Facility managers, building owners and consultants evaluating system suitability for residential and commercial properties.
• Use cases commonly include buildings where gravity drainage is impractical, space-constrained sites, or installations requiring flexible piping layouts (note: the standard applies only to domestic wastewater, not stormwater).

Related Standards

• Published by CEN, EN 12109 should be used alongside other European and national standards covering plumbing, wastewater management, and building services to ensure comprehensive compliance.
• Users should consult local regulations and complementary standards for materials, backflow protection, and environmental discharge requirements.

EN 12109 is an essential reference for anyone specifying, installing or testing vacuum drainage systems for domestic wastewater in buildings, providing standardized performance, design and verification practices across Europe.
