Primary metering equipment
To comply with the floodplain harvesting measurement rules, you will need to install primary metering equipment.
There are two methods for measuring floodplain harvesting, storage measurement or point-of-take measurement, each requiring specific primary metering equipment.
Engage a duly qualified person (DQP)
Engage a specialist DQP, in this instance a Certified Storage Meter Validator (CSV), to discuss the appropriate installation method and measurement equipment for your on-farm needs.
A CSV will register, install and validate your storage meter in the WaterNSW DQP Portal.
See the list of compliant storage sensors and compatible local intelligence devices for floodplain harvesting.
A list of CSVs can be found on the:
Register a storage curve
Storage metering equipment measures the depth of water in a storage. This depth is converted to a volume using the storage curve.
You must ensure the most up-to-date storage curve is registered by your DQP in the WaterNSW DQP Portal. Your DQP/CSV can provide you with a copy of your default storage curve. It is up to you to ensure that this information is correct. Please refer to the department’s Storage Curve Guideline (PDF, 268 KB) for further information.
Install survey benchmarks
Survey benchmarks to Australian Height Datum (AHD) are critical for the installation of floodplain harvesting measurement equipment. Levelling and positioning metering equipment to AHD links the meter to the storage curve.
Survey benchmarks must be installed by a DQP – in this instance, a registered surveyor or persons approved by the Minister.
You may use existing survey benchmarks if they are validated by a registered surveyor and conform to the department’s Survey benchmark standard (PDF, 2.4 MB) and Survey benchmark guideline (PDF, 909.82 KB).
Note: Survey benchmarks can be established after both primary and secondary measurement equipment are installed. This will minimise surveying visits and costs during the installation phase.
Report faulty metering equipment
You must notify the Minister (via WaterNSW) within 24 hours of becoming aware that any component of your metering equipment is faulty or telemetry has failed. Reports are made using the S91i self reporting form on the WaterNSW website.
Request an extension to replace faulty equipment:
You have 21 days from the time you lodge your faulty meter form to repair or replace the faulty metering equipment. Requests for an extension beyond 21 days can be made using the S91i extension form on the WaterNSW website.
Advise us that the equipment has been repaired or replaced:
After faulty metering equipment has been repaired or replaced, you must advise the Minister by completing the S91i completion form on the WaterNSW website.
Floodplain harvesting while repairs are being made
You can continue to floodplain harvest while repairs to your primary metering equipment are being made, using a secondary metering device.
Telemetry exemption for floodplain harvesting
The Minister has granted an exemption for floodplain harvesting works that are required to connect to telemetry but cannot because they are in a network black spot.Find out about the telemetry exemption
