AS4747-2025: What the New Water Metering Standard Means for You
The updated Australian Standard for non-urban water meters (AS4747-2025) came into force in June 2025. If you're extracting water under license, whether for irrigation, stock, or other purposes. Here's what you need to know.
What's Changed?
The new standard doesn't introduce new technology. It tightens the rules around proving that metering systems work as intended.
In practical terms: regulators are looking more closely at whether your meter data can be trusted, and whether you can document it. There's greater emphasis on proper installation, validation records, and increasingly, telemetry.
Who's Affected?
Requirements vary by state and entitlement size, but the key thresholds are:
Over 100ML entitlement: Pattern-approved AS4747 meter, DQP installation, and telemetry required
Bores 200mm+ with 100ML+ entitlement: Now require telemetry
Coastal NSW users (100ML+): Must comply by December 2026
The $22.6 million federal Telemetry Uplift Program is funding device installations across the Murray-Darling Basin, if you're eligible, you may get telemetry installed at no cost.
What You Should Do
Check your entitlement size and confirm which requirements apply
Review whether your current meter is pattern-approved
Talk to your water corporation or DQP about validation and telemetry
Check eligibility for the Telemetry Uplift Program
How Halytech Supports Compliance
Halytech has been building reliable monitoring and telemetry equipment in Australia for over two decades. Two products are particularly relevant here:
Meterwatch is a compliance-focused data logger approved by WaterNSW for reporting to the Data Acquisition Service (DAS). It captures meter readings and transmits them to water authorities automatically. Designed for installation by qualified persons, it simply does what it's meant to do: log data and report it reliably.
MicroSpider2 Environmental offers a more flexible and robust solution for users who need to report to systems other than the DAS. With configurable outputs, multiple sensor inputs, and proven reliability in remote locations, it suits applications where you need more control over where your data goes and what you're monitoring.
Borewatch is purpose-built for bore monitoring. It tracks water levels, flow, and usage from groundwater bores, exactly what's needed as telemetry requirements expand to bores 200mm and larger under the new rules.
All three are Australian-designed, Australian-built, and backed by local support.
