Benefits of Water Meters

Water is a publicly owned resource to which water licence holders are granted exclusive access and all water licence holders have an obligation to be accountable for the water they take under their licence. Therefore, all licensees must maintain a record of the volume of water they take under their licence (refer to Accounting for your Water Fact Sheet).

There are a number of ways that the volume of water taken may be accounted for. Unless otherwise directed by the Minister to install a meter, a licence holder is able/allowed to determine the methodology to account for the taking of water that best suits their circumstances.

Water meters are recognised as one of the most reliable methods to measure and account for water taken under water licences. Metering provides benefits to water users as well as water managers particularly in areas where water management is complex and requires a high level of accountability.

Benefits to the licence holder of meters include:

  • better monitoring of on-farm water use and irrigation efficiency to support business planning and improvement;
  • better monitoring of pump and irrigation system performance;
  • improved matching and optimisation of irrigation to crop water requirements;
  • Demonstrated water use accountability supporting accreditation.

Metering will also assist  water managers to better manage Tasmania's water resources by:

improving information on water taken under water entitlements to inform improved policy and management practices;

facilitating better water resource management and planning to provide the optimum economic, social and environmental outcomes from water use;

enabling improved compliance with licence conditions and restrictions to ensure the protection of both water users' legal entitlements and the environment.


Selection and Installation

In all cases where meters are required under water licence conditions, it is the responsibility of the licensee to make sure that appropriate meters are purchased and installed. In Tasmania, the standard for specification, installation, validation and maintenance of non-urban water meters is the Tasmanian Standard for Non-Urban Water Meters.

The Tasmanian Standard’s primary objective is to provide an acceptable level of confidence that non-urban water meters have been manufactured, installed, commissioned and maintained such that measurement performance under in situ conditions is within the maximum permissible limits of error of plus or minus 5%.

The Tasmanian Standard for Non-Urban Water Meters contains detailed and technical specifications for non-urban water meter installation, commissioning, maintenance and validation. Therefore, it is strongly recommended that, even when installed voluntarily, meters are installed and commissioned by an Irrigation Australia Limited Certified Meter Installer and Validator both to ensure the meter functions accurately and to minimise the potential for any costly repairs and modifications to correct faulty installations.

A list of Irrigation Australia Limited Certified Meter Installers and Validators can be found at: http://irrigation.org.au/certification/listing-of-other-certified-irrigation-professionals-2

If meters are not installed and commissioned by an Irrigation Australia Limited Certified Meter Installer and Validator the onus is on the meter installer to install the meter in accordance with the Tasmanian Standard, including the relevant sections of the Australian Standard AS 4747.
