Description (English):

ISO 20760-1:2018 provides guidelines for the planning and design of centralized water reuse systems and water reuse applications in urban areas. ISO 20760-1:2018 is applicable to practitioners and authorities who intend to implement principles and decisions on centralized water reuse in a safe, reliable and sustainable manner. ISO 20760-1:2018 addresses centralized water reuse systems in their entirety and is applicable to any water reclamation system component (e.g. source water, treatment, storage, distribution, operation and maintenance and monitoring). ISO 20760-1:2018 provides: - standard terms and definitions; - system components and possible models of a centralized water reuse system; - design principles of a centralized water reuse system; - common assessment criteria and related examples of water quality indicators, all without setting any target values or thresholds; - specific aspects for consideration and emergency response. Design parameters and regulatory values of a centralized water reuse system are out of the scope of this document.

Abstract

Overview

ISO 20760-1:2018 - Water reuse in urban areas: Guidelines for centralized water reuse system - Part 1: Design principle of a centralized water reuse system provides guidance for planning and designing centralized water reuse (reclaimed water) systems in urban areas. The standard addresses the full system lifecycle - from source water selection and treatment through storage, distribution, operation and maintenance, monitoring, and emergency response - while avoiding prescriptive numeric targets. ISO 20760-1 is intended for use by practitioners and authorities who need to implement centralized water reuse in a safe, reliable, and sustainable way.

Key topics and technical requirements

System scope and terminology: Standardized terms and definitions to support consistent planning and communication across projects and stakeholders.
System components and models: Describes possible models for centralized water reuse systems (e.g., single application, multiple applications, environmental storage, cascading uses) and component interactions.
Design principles: Core design principles emphasizing safety, reliability, stability, economic viability, and environmental considerations for centralized water reuse systems.
Source water considerations: Guidance on types of source water (treated effluent, raw wastewater, alternative sources), quality and reliability assessment, and economic factors.
Treatment and storage: High-level guidance on centralized treatment system configurations, storage types (open/closed reservoirs, aquifer storage and recovery), turnover and water-quality control, and post-treatment needs.
Distribution and transmission: Principles for distribution system design, pipeline materials and layout, pumping station design, avoiding stagnation, and color-coding/labeling for reclaimed water networks.
Monitoring and control: Recommended monitoring locations and facilities for source water, treatment processes, storage, distribution, and user sites - including operational monitoring and control systems.
Emergency response: Requirements for planning and procedures to respond to contamination events or service interruptions.
Assessment criteria: Common assessment criteria and example water quality indicators are provided, but the standard does not set target values or regulatory thresholds.

Applications

ISO 20760-1 is practical for:

Urban planners and municipal authorities developing water reuse strategies.
Water utilities and wastewater treatment operators designing centralized reclamation and distribution systems.
Consulting engineers and design teams specifying treatment, storage, and transmission infrastructure.
Regulators and policymakers seeking harmonized terminology and design guidance for urban water reuse projects.

Related standards

Part of the ISO 20760 series on water reuse; consult other parts of the series for complementary guidance.
Developed by ISO/TC 282 (Water reuse), and intended to be used alongside local regulatory requirements and technical codes.

Keywords: ISO 20760-1, water reuse, centralized water reuse system, reclaimed water, urban water reclamation, design principles, water reuse guidelines.
