Water Efficiency Management Systems
Specifies requirements for establishing, implementing, maintaining, and improving a water efficiency management system for any organisation seeking to reduce water consumption.
ISO 46001 specifies requirements for water efficiency management systems, enabling organisations to systematically identify, monitor, and reduce water consumption. It mirrors the energy management approach of ISO 50001, applying it to water resources management.
The standard applies to any organisation regardless of type, size, or sector, from large industrial water users to commercial buildings, agricultural operations, and municipalities. It helps organisations establish baselines, identify significant water uses, and implement targeted efficiency measures.
ACI-certified auditors assess water efficiency management systems, evaluate water use data quality, and review the effectiveness of water reduction action plans and controls.
