ISO 46001 Consulting: Build a Water Efficiency Management System That Is Ready for Certification

ISO 46001 is the international standard for water efficiency management systems. It applies to organisations of all types and sizes that use water, and it is voluntary: you need it only if you want a recognised, auditable system or your customers and investors ask for one. A water audit is often the first step.

ISO 46001 consulting covers gap assessment, water use review and baseline, targets and action plans, documentation, internal audit, certification readiness and support through the certification audit. We prepare you; an independent certification body certifies you.

Our tyre manufacturer project took four months, from gap assessment to certification support. Plan on about four months where water is already metered, and longer where meters must be added. Your quote carries a dated plan.

A water use review maps where water comes in, where each process uses it, where it is lost and where it is recycled, and it sets the baseline you measure against.

No. ISO 46001 is a management system for using water efficiently, while a neutrality claim rests on water accounting and replenishment. The two work well together. See our water neutrality consulting service.

No. We do not issue ISO or other certificates; independent certification bodies do. We prepare the evidence and systems so certification goes smoothly.

Yes. It is built like other ISO management system standards, so you can share the policy framework, document control, internal audit and management review where your standards allow.

ISO lists the standard as "to be revised" since July 2025, and a new draft is under development. The 2019 edition, with its 2024 amendment on climate action, is the version in use today, and we will update our method when a new edition is published.

Yes. Consultivo provides ISO 46001 consulting to sites across India, and the same method applies in the 20+ countries where we have worked.

No. Where we advised on or built the system behind a number, we do not assure that number, so your assurance provider stays independent of us. Read our Independence and Impartiality Policy.

The number of sites, how much you already measure, the systems you already run and the depth of support you want. We quote after a short scoping call.
