Southern Valleys Metering Project

Southern Valleys Metering Project


  • The National Water Initiative (NWI) is an agreement between the Australian Government and states/territories which includes the development of national metering standards, including meter-related data collection.
  • The NSW Metering Scheme is being carried out in a staged approach to enable NSW to comply with the national metering standards.
  • The scheme aims to improve accuracy and fairness by ensuring at least 95 percent of total extractions in the regulated, unregulated river and groundwater systems are metered.
  • WaterNSW is implementing the NSW Metering Scheme on behalf of the regulatory authority, DPI Water. To date, more than 1,300 new water meters have been installed in southern NSW through the scheme.
  • WaterNSW is also using the opportunity to enhance customer service.

The Southern Valleys Metering Project

  • The $31.5 million Southern Valleys project will see a further 700 new water meters installed across the Murray, Murrumbidgee and Lower-Darling valleys in 2015-16.
  • The new water meters will be fitted with telemetry, a vital link in providing water usage data to improve the efficiency of river operations, and ensure prompt monitoring of water extraction.
  • The first installations commenced in May 2015 following a consultation process with customers to discuss their specific site requirements.

Project progress

  • At the end of May 2016, contractors Comdain John Holland Joint Venture (CJHJV) had:
    • Made initial inspections of 710 Southern Valleys sites
    • Completed 709 detailed designs
    • Installed 425 meters in the Murray and Lower Darling Valleys
    • Installed 279 meters in the Murrumbidgee Valley
  • The project is on schedule for completion mid-2016.


  • Installation of the new meters will help customers meet their requirements under the national metering standards, called the Metrological Assurance Framework (MAF).
  • The MAF prescribes that all meter owners must comply with requirements including meter installation to certain specifications, regular maintenance and assessments to ensure meters are working correctly.
  • The Water Management Act 2000, under which your Works Approval is governed, sets out requirements to install, maintain and operate any device or devices for measuring the volume of water extracted by the approved works.

Your options

  • If you do not require a meter as you will no longer be using these identified works for extractions, please contact your WaterNSW Customer Field Officer (CFO) on 1300 662 077.
  • Customers who are required to have a meter under their works approval and who choose not to
    participate in the NSW Metering Scheme will be required to install any necessary meter at their own cost.

Consultation process

  • Customers selected for the project will be contacted by their CFOs or a representative of the contractors to discuss their specific site requirements and arrange a time to visit the site.
  • Potential site designs will be developed and submitted to WaterNSW.
  • Further information on the consultation process is available.

About the meters

Electromagnetic flow meters

Electromagnetic flow meters (also known as magflow meters) will be used on pipe or closed conduit systems due to their:

  • Accuracy;
  • Comparatively low maintenance;
  • Lack of moving parts; and
  • Lower susceptibility to sand and vegetation contamination compared with mechanical meters.

In some situations non-electromagnetic meters may be used where site conditions dictate this requirement or it is more cost efficient to do so.

Meter operation

  • The pipe area within the meter is rigid and set.
  • The flow through the pipe is variable and the speed or velocity is measured.
  • The meter is lab tested and a certificate of accuracy provided with each meter.
  • More information on meters and accuracy is available in the meters, telemetry and accuracy information sheet (PDF 170KB)
  • The meters used have also undergone extensive testing as part of the Pattern Approval certification. Testing indicated typically, meters installed in the field are delivering accuracy errors of less than ±1.5%. Further information is available in the Meter Pattern Approval document (PDF 327KB). 


  • The Remote Telemetry Unit (RTU) is paired to the individual meter and contains the unique characteristic of the meter.
  • Meter readings are recorded every 15 minutes.
  • The RTU will transmit meter data to databases hourly, daily or weekly, allowing meter readings to be accessed remotely.

After your meter is installed

Ordering water

Metering service charge

  • A metering service charge (MSC) will be applied to your account to cover the ongoing costs of meter operation and maintenance as well as remote meter reading and data information processing in line with the National Water Metering Standards. Information on the MSC is available here.

Meter maintenance contact

  • If there is an issue with your new meter please contact WaterNSW on 1300 662 077.
  • For assistance out-of-hours, a message can be left on the 1300 number or in emergencies, press 2 to be diverted to a staff member for further assistance.

Meter reads

  • Meter readings are recorded every 15 minutes and transmitted to databases to allow readings to be accessed remotely
  • Our CFOs will continue to visit properties from time-to-time as needed to inspect, test and maintain meters in accordance with the National Water Metering Standards.
  • The on-site meter display will show customers their extraction (or pump) rate and the total water volume extracted since installation.
