Many "free" PDFs floating around are obsolete versions. In engineering, using a 20-year-old flow rate calculation can lead to catastrophic pipe failures or backups.

The standard specifies that materials must be suitable for the intended use, resistant to wastewater, and durable.

is the definitive European standard governing the core design and performance principles of gravity drainage systems within residential, commercial, and industrial buildings. Rather than diving straight into calculations, this initial part establishes the foundational framework required to prevent structural flooding, foul odors, and catastrophic mechanical failures across all plumbing frameworks.

Covers the design of pipework for wastewater, with limited provision for specialized trade effluent.

Are you designing a system or a commercial/industrial facility? Covers the design of pipework for wastewater, with

The standard applies to drainage systems within:

The pipework must be sized correctly to handle peak flow rates without overflowing or backing up.

All internal pipework, joints, and connection points must be permanently watertight and gas-tight. This prevents physical property damage from leaks and eliminates the risk of airborne pathogens or toxic gas exposure. 3. Self-Cleansing Capability
