what is ISO 46001:2019 - Water efficiency management systems?

Water scarcity is one of the most significant global risks and is set to increase further over the next decade. The pressure on organisations to implement a sustainable water management plan is paramount to reduce water demand from the non-domestic sector and encourage water conservation.

ISO 46001:2019 specifies requirements and contains guidance regarding organisational water use. ISO 46001 includes monitoring, measurement, documentation, reporting, design and procurement practices for equipment, systems, processes, and personnel training that contribute to water efficiency management. The ISO 46001:2019 water efficiency management system applies to organisations of all types and sizes that use water and is focused on end-use consumers. An effective water efficiency audit helps organisations to identify gaps in the existing water management processes and reduce water wastage.

  1. Identifying water as a resource can be considered part of organisational and budgetary planning.
