ISO 46001:2019
Optimise Water Resource Management According to International Standards
Based on Singapore’s national water management model, renowned for its world-class efficiency, ISO 46001 serves as a global standard for sustainable operational strategy
Water Resource Pressures on the Manufacturing Sector
Water resources are increasingly becoming a strategic variable in operations—both as a rising cost factor and as an element subject to growing scrutiny under global standards
– 36% of industrial parks in Vietnam face a high risk of severe water shortages during the dry season, directly impacting production activities
– Water costs for industrial production are projected to increase by 20–30% over the next five years, placing significant pressure on businesses
– More than 50,000 European companies are subject to the CSRD, requiring Vietnamese businesses within their supply chains to ensure transparency of water-related data in ESG reporting.
Businesses
A Pioneering Factor in the Journey to Protect Water Resources
Efficient Water Use – A Present Responsibility, A Future Strategy
In the context of declining water resources, many industries - particularly manufacturing and processing - are facing increasing operational risks. Therefore, organisations need to proactively:
Optimise production processes to reduce water consumption.
Implement wastewater reuse and recirculation technologies.
Ensure compliance with environmental standards across the entire value chain.
These improvements enable businesses to reduce costs while strengthening credibility and enhancing investment attractiveness. In this context, ISO 46001 serves as a strategic tool that enables organisations to manage water in accordance with international standards, providing a solid foundation for sustainable development
ISO 46001:2019 Standard Overview
An international framework enabling organisations to use water efficiently and sustainably
ISO 46001 is an international standard for Water Efficiency Management Systems (WEMS), providing a comprehensive framework for managing and optimising water use within organisations.
This standard helps organisations reduce costs, minimise resource waste, and demonstrate environmental responsibility—an aspect that is increasingly valued by customers, investors, and global supply chains.
Through its core requirements, ISO 46001 enables organisations to:
Accurately assess current water use through data-driven and scientifically based methods
Establish improvement objectives aimed at reducing consumption and enhancing water use efficiency
Integrate water management into operational strategies and sustainable development initiatives
Practical Impacts of
ISO 46001:2019
Data-driven management rather than intuition-based decision-making
A measurement system enables organisations to clearly identify where water is being consumed, the causes of inefficiencies, and potential leakage points
Optimise the operation of the entire water system
From water supply to discharge and recirculation, organisations can both reduce costs and alleviate pressure on infrastructure and the environment
Proactively address water scarcity
Water-saving and reuse solutions are integrated into production processes, helping to reduce the risk of operational disruptions
Enhance compliance and transparency
Standardised data that can be readily integrated into ESG reporting, meeting audit requirements and demonstrating environmental responsibility
Which Organisations Are Required
to Obtain ISO 46001:2019 Certification?
Any organisation that uses water at a significant scale, particularly in manufacturing and service operations - should adopt ISO 46001 to optimise operations and meet regulatory and ESG requirements
