ISO 46001 Certification Implement Sustainable Water Efficiency Management Systematically

About 70% of the Earth’s surface is covered by water, but only a small fraction of it is potable freshwater. Additionally, pollution, droughts, and the growing global population are further reducing the available water resources.

Water is one of the most valuable resources of our time — and efficient usage is becoming a decisive competitive factor for businesses.

ISO 46001 provides a systematic framework for companies and organizations to monitor their water consumption, identify saving potentials, and implement sustainable processes.
With an ISO 46001 certification, you demonstrate your commitment to sustainable water management to business partners, authorities, and the public.

What is ISO 46001?

ISO 46001 is an internationally recognized standard for Water Efficiency Management Systems (WEMS).
It helps companies reduce water consumption, optimize resource use, and sustainably improve operational efficiency.

Initial offer

We start by analyzing your company and any existing water management systems. Together, we define goals related to sustainability, resource efficiency, and cost savings. Based on this, our experts prepare a transparent offer tailored to your operational needs.

Certification audit

The certification process begins with Audit Stage 1 (System Analysis), where we review your documentation, objectives, management review results, and internal audits to assess if your water efficiency management system is sufficiently prepared and ready for certification.
Next, Audit Stage 2 (System Audit) involves an on-site evaluation by your auditor of the implementation and effectiveness of all relevant management processes. The results are documented in a detailed audit report.

ISO 46001 Certification

Once all ISO 46001 requirements are met, you receive a certificate officially confirming the conformity of your water management system with the global standard.

Surveillance audit

Annual surveillance audits ensure your management system continues to meet ISO 46001 requirements over the long term, keeping your certification valid and up to date.

Recertification

Certificates are valid for a maximum of three years. Before expiry, we conduct a recertification to confirm ongoing compliance with all relevant standards. Upon successful review, a new certificate is issued. Recertification occurs every three years to guarantee continuous conformity.
