Gravity drainage systems inside buildings - Part 2: Sanitary pipework, layout and calculation
This European Standard applies to waste water drainage systems which operate under gravity. It is applicalbe for drainage systems inside dwellings, commercial, institutional and industrial buildings. Differences in plumbing within Europe have led to a variety of systems being developed. Some of the major systems in use are described but this standard has not attempted to detail the intricacies of each system. Detailed information additional to that contained in this Standard may be obtained by referring to the technical documents listed in Annex A.
Schwerkraftentwässerungsanlagen innerhalb von Gebäuden - Teil 2: Schmutzwasseranlagen, Planung und Berechnung
Diese Europäische Norm gilt für Entwässerungsanlagen, die unter Schwerkraft betrieben werden. Sie gilt für Entwässerungsanlagen innerhalb von Wohngebäuden, Geschäfts-, Instituts- und industriellen Gebäuden. Die Unterschiede in Planung und Bau von Entwässerungsanlagen in Europa haben zu einer Vielzahl von Anlagenausführungen geführt. Einige der gebräuchlichsten Anlagenarten werden nachfolgend beschrieben. Diese Norm beschreibt nicht die Einzelheiten jeder Anlagenausführung. Die in Anhang A aufgeführten Unterlagen enthalten Einzelheiten und Hinweise, die im Rahmen dieser Norm verwendet werden dürfen.
Réseaux d'évacuation gravitaire à l'intérieur des bâtiments - Partie 2: Systèmes pour les eaux usées, conception et calculs
La présente Norme s'applique aux installations d'évacuation gravitaire des eaux résiduaires. Elle s'applique aux installations d'évacuation des eaux résiduaires dans des habitations, immeubles commerciaux, institutionnels, artisanaux et industriels. Les différentes habitudes d'installation en Europe ont généré une multitude de systèmes. Une partie des systèmes principaux utilisés sont décrits dans cette norme. La présente norme n'essaie pas de démontrer les détails et complexités de chaque système. Les documents dont la liste est donnée en annexe A contiennent des détails, lesquels peuvent être utilisés dans la cadre cette norme.

Overview
EN 12056-2:2000 is a CEN European standard covering gravity drainage systems inside buildings, specifically sanitary pipework, layout and calculation. The standard applies to gravity-operated wastewater drainage in dwellings and commercial, institutional and industrial buildings. Because plumbing practice varies across Europe, the standard describes major system types without attempting to detail every national variation - additional technical guidance is referenced in Annex A.
Key Topics
The standard addresses practical design and engineering considerations for building drainage systems, including:
- Sanitary pipework layout - principles for arranging internal drainage runs and stacks to serve fixtures efficiently.
- Hydraulic calculation - methods for estimating flowloads and for sizing pipes and stacks to handle expected wastewater flows under gravity.
- System compatibility - guidance on interfacing internal drainage with external sewers or foul water systems.
- Design for maintainability - provision for access points, inspection chambers and cleaning facilities to allow safe operation and maintenance.
- Accommodation of national variants - notes on commonly used system types across Europe while pointing to further technical documents in Annex A.
(Note: EN 12056-2 describes scope and methods rather than prescriptive national installation minutiae. It does not attempt to exhaustively specify every local plumbing variation.)
Applications
EN 12056-2:2000 is used to:
- Design and calculate internal gravity drainage systems for residential, commercial, institutional and industrial buildings.
- Produce compliant layout drawings and specifications for plumbing contractors and installers.
- Support building services engineering, ensuring appropriate pipe sizing, fall/gradient and routing for sanitary waste.
- Inform retrofit and extension projects where existing drainage must be adapted or expanded.
- Serve as a reference in tender documents and regulatory compliance checks where CEN standards are adopted nationally.
Who should use this standard
- Building services engineers and plumbing designers
- Architects coordinating building utilities and layouts
- Plumbing contractors and installers responsible for implementation
- Facilities managers planning maintenance and upgrades
- Regulators and certifiers assessing compliance with European drainage practice
Related standards
- Other parts of the EN 12056 series and national plumbing regulations provide complementary guidance and prescriptive installation details. Refer to Annex A of EN 12056-2 for additional technical documents and further reading.
