ISO 46001:2019 – Water Efficiency Management System (WEMS): Gaining Momentum Across Industries

Water is one of the most critical resources for sustaining life and industry. With increasing pressure on freshwater availability, organizations are realizing the importance of managing water responsibly. The ISO 46001:2019 Water Efficiency Management System (WEMS) provides a structured framework for organizations to manage and reduce water usage, based on the 3R principles – Reduce, Reuse, and Recycle. This standard helps organizations systematically evaluate, plan, and execute water utilization strategies, thereby reducing dependence on freshwater withdrawals for their operations. This article explores: • How ISO 46001 aligns with other ISO management systems for easy integration, • The key technical requirements, such as water measurement, balancing, and efficiency KPIs, and • The benefits and pathways toward water neutrality and circularity.
