What is ISO 46001?
ISO 46001 is a management system standard for organisations seeking a structured approach to water efficiency. It addresses reducing demand, considering suitable alternative water sources and reuse. ISO 46001:2019 and its 2024 climate change amendment form the reference framework when assessing the application.
Who can use it?
Manufacturing sites, hotels, commercial buildings and other water users can define a scope suited to their operations. Start by identifying site boundaries and significant water uses. This is an organisational management system, not a product certificate confirming water quality.
Preparing for assessment
Map incoming water, consumption points and losses. Compare meter readings and bills with production or activity data to select meaningful performance indicators. Assign responsibilities, deadlines and resources to improvement actions. Internal audits and management review help check whether the system works in daily operations.
Certification and quotation
Share your activities, number of sites, workforce, existing management systems and requested scope. Application review is followed by audit planning, assessment of documentation and implementation, correction of any nonconformities and a certification decision. Confirm the available certification scope and any accreditation before contracting. Duration and fees depend on the scope and readiness of the organisation.
Is this the same as ISO 14046?
No. ISO 14046 concerns water footprint assessment; ISO 46001 focuses on the processes used to manage water efficiency over time. One does not automatically replace the other. No fixed saving percentage can be guaranteed: results depend on baseline consumption and implemented improvements. Contact our Belgium office with your site details to discuss the next steps.
