Non-urban water metering framework and guidelines

States and territories have agreed on a national approach to non-urban water metering.

Use the framework and guidelines to ensure you understand how to comply.

Metrological Assurance Framework 2

All Australian states and territories, 2021

The Metrological Assurance Framework 2 (MAF2) sets out requirements for non-urban metering.

It means:

• higher confidence in meter accuracy
• easier methods to ensure meter accuracy
• consistent regulation of water metering across Australia
• better compliance data for water users, regulators, meter installers and manufacturers.

You can find more guidance on state or territory websites.

The MAF2 replaces the original (2009) Metrological Assurance Framework.

Pattern Approved meters

All Australian states and territories

All non-urban water meters must be Pattern Approved to the Australian Standard for non-urban water meters (AS4747). This applies to new and replacement meters. Meters are Pattern Approved by the National Measurement Institute of Australia.

We publish the list of Pattern Approved meters.

Metering thresholds

All Australian states and territories, 2018

All states and territories have agreed on guidelines for non-urban water metering thresholds. Regulators use these best practice guidelines to design their metering policies.
