Overview - EN 806-1:2000 (Specifications for drinking water installations - Part 1: General)
EN 806-1:2000 is a European CEN standard that sets out general principles for installations inside buildings conveying water for human consumption. It covers the system of pipes, fittings and connected appliances installed to supply drinking water within buildings and, in certain cases, pipework outside buildings but within the premises. The standard addresses requirements and recommendations for the design, installation, alteration, testing, maintenance and operation of drinking water installations.
Key topics and technical scope
The standard provides general guidance and requirements related to:
- Design principles for safe, hygienic and functional drinking water distribution in buildings
- Installation practices for pipes, fittings and connected appliances to ensure integrity and water quality
- Alteration and modification procedures for existing installations to maintain compliance and safety
- Testing and commissioning methods to verify correct operation before use
- Operation and maintenance requirements to preserve system performance and prevent contamination
- Scope of applicability, clarifying which inside-building and premises pipework are covered
- Interfaces with water-using appliances and requirements for connected equipment
Note: EN 806‑1 is the general/introductory part of the EN 806 series; it establishes overarching concepts rather than prescriptive technical values.
Practical applications and users
EN 806-1 is relevant to professionals and organizations involved in the lifecycle of building water systems, including:
- Plumbing designers and engineers preparing layouts and hydraulic designs
- Installers and contractors implementing compliant plumbing systems
- Facility managers and building owners responsible for safe operation and maintenance
- Inspectors, regulators and health authorities assessing compliance with drinking water safety expectations
- Consultants and water utilities advising on building connections and hygiene risk reduction
Use cases include new building design, retrofits and alterations, commissioning of systems, routine maintenance planning, and risk-based inspections.
