TC282/SC2 Scope
Standardization in the field of water reuse in urban
areas. It addresses wastewater reclamation and
reuse in urban areas. It includes guidelines for
design and management of water reuse systems
taking into consideration safety, reliability and
efficiency. It covers both centralized (community-
wide) and decentralized (on-site) water reuse
systems. The standardization process covers the
reclamation, storage and distribution parts of water
reuse systems in urban areas.

ISO 20760-1 Design Principle of a Centralized Water Reuse System
• The standard provides guidelines for the planning and design of centralized
water reuse systems and water reuse applications in urban areas.
• It addresses system entirety and is applicable to any water reclamation
system component (e.g. source water, treatment, storage, distribution,
operation and maintenance and monitoring).
Possible models:
• Single application
• Multiple applications
• Environmental storage
and reuse applications
• Cascading reclaimed
water uses

A new standard on water reuse could make a significant impact for water scarcity. ISO 20760-1 offers guidelines on how to make use of reclaimed water in order to satisfy water demands and alleviate heavy pressure on urban areas.
ISO 20760-1 Design Principle of a Centralized Water Reuse System
• Technical approaches
- Multiple barrier approach and monitoring system
- Minimum technological requirement
9
ISO 20760-2 Management of a Centralized Water Reuse System
• Management approaches
- Water quality monitoring
- Daily management (HACCP-Hazard Analysis and Critical Control Point)
• The standard provides principles and methodology of reclaimed water
management
• Management issues in each system component
• Specific aspects for consideration and emergency response
Wastewater Reclamation process
(water quality safeguard)
Supply and storage
(Water-quality
degradation control)
End uses
(Risk control)
Risk assessment
Economic analysis
• Sources of reclaimed water
• Reclaimed water treatment system
• Reclaimed water distribution system
• Reclaimed water storage system
10
ISO 20761 Water Reuse Safety Evaluation
Framework of water reuse safety evaluation
• This document provides water reuse safety evaluation and public
acceptance parameters and methods for users who design, manage,
and/or oversee the non-potable water reuse schemes or activities in urban
areas from the viewpoint of water quality.
• The document can be used in various stages of non-potable water reuse
projects such as design, operation, and post assessment.
