Metering and measurement
Progress on actions to September 2019.
Actions 3.1 to 3.6: Publish a metering policy that addresses meter accuracy (action 3.2), meter coverage (action 3.3), transmission of data (action 3.4), metering and telemetering of high risk take (action 3.5), and timeline for the installation of new metres and telemetry (action 3.6)
Victoria implemented the National Framework for non-urban water metering via a state-wide non-urban water metering policy (2014) and implementation plan which have guided installation of Victoria’s non-urban water metering fleet, the largest and most advanced of its kind in Australia.
Victoria has comprehensive meter coverage with about 57,400 non-urban water meters and about 52 per cent are telemetered. Victoria’s water corporations have been national leaders in adopting telemetry and automated control systems.
DELWP commenced a review of its existing policy in October 2018. The review was completed in June 2019 and involved several stages to understand the implications of strictly adhering to the requirements in the Compact:
- a stock-take of the current metering assets in Victoria
- a gap analysis of the existing metering policy and the Compact requirements
- a regulatory impact assessment of complying with the Compact requirements
- recommendations on changes to the existing metering policy and exemptions from the Compact requirements where the costs to implement outweigh the benefits.
The results of the review show that Victoria is already meeting the metering requirements of the Compact (actions 3.2 to 3.6) that to the extent that it is cost-effective to do so. As these documents are already published, the requirements of this action have been met. To confirm and to refresh the state’s policy on non-urban water metering, a revised policy is being prepared which will supersede the existing policy and state implementation plan.
The draft revised non-urban metering policy has been released for targeted consultation with water corporations with non-urban customers, Victorian Environmental Water Holder, Victorian Farmers Federation, and the Murray-Darling Basin Authority. The consultation will close on 20 September 2019 and is expected the policy will be finalised for approval in October 2019. When the policy is finalised an exemption statement will be published on DELWP’s website that describes where the policy varies from the requirements of the Compact because the risks are manageable, or metering is not cost-effective.
VIC 3.1: Publish guidelines to support the development of Implementation Plans for metering by rural water corporations and publish Implementation Plans in accordance with the guidelines
DELWP has prepared a set of guidelines for water corporations to update their metering action plans. The guidelines set out the key elements water corporations should have in their metering action plans, including:
- Business context relevant for metering requirements, future metering upgrades and their timing
- Processes to ensure accurate meters
- Meter data management
- Meter fleet profile
- Meter investment plan and finances.
The guidelines will not be published until the revised non-urban water metering policy is approved and published.
Water corporations are expected to revise their metering action plans by 30 September 2019. In drafting the metering action plans, DELWP also engaged a contractor, SMEC, to work with water corporations to update their metering action plans in accordance with the draft revised metering policy and draft metering action plan.
Action 3.7: Report annually on progress with above implementation plan
To commence on 30 September 2019
Action 3.8: Set a timetable for delivering a comprehensive range of pattern approved meters
Led by the MDBA.
MDBA provides updated lists of Pattern Approved ‘Non-Urban’ Water Meters on its website.
Action 3.9: NSW and Queensland will publish their respective programs for improved measurement of floodplain harvesting and overland flow harvesting
For NSW and Queensland only
Action 3.10: Publish a review of its water information requirements for compliance and enforcement and a water information improvement program for addressing priority issues
Victoria completed a review of its hydrometric network of surface water gauges, groundwater bores and climate (rainfall and evaporation) stations. The report (PDF, 1.7 MB) of the completed review identifies a program of continuous improvement in surface water and groundwater monitoring.
Action 3.11: Report annually on their progress against the above water information improvement program
To commence on 30 September 2019
Action 3.12: Conduct and publish a review every 5 years of their water information system
To commence as per state programs
VIC 3.2: Victoria estimates water use, in the event of meter failure, as provided for in section 142(2) of the Victorian Water Act and section 3.7 of the Customer Service Code for Rural Water Corporations
VIC 3.3: Victoria accounts for water use from small catchment dams and domestic and stock bores, uses best endeavours to improve these accounting methods over time, and periodically reviews the long-term risks to Victoria’s water resources through mechanisms such as long-term water resource assessments and sustainable water strategies
The Victorian Water Accounts are publicly available.
VIC 3.4: Victoria operates its flow monitoring network in line with best practice, including minimisation of data loss
VIC 3.5: Victoria will undertake an audit of its monitoring network control structure condition and prepare a prioritised work program
An independent audit by ALS of Victoria’s surface water monitoring control structure in northern Victoria (PDF, 1.8 MB) was completed in June 2019.
VIC 3.6: Victoria will document water resource assessment tools and models to meet Basin Plan compliance obligations, and will submit the relevant documentation to the Commonwealth as part of the existing water resource plan accreditation process
As required under Chapter 10, Part 4 of the Basin Plan, Victoria’s water resource assessment tools and models to meet Basin Plan compliance obligations have been incorporated into its water resource plans.
In the Wimmera-Mallee Water Resource Plan, a summary of the methods used to determine sustainable diversion limits and take is in Part 8 (PDF, 507.6 KB), supported by further information in Appendix C (PDF, 908.7 KB).
In Victoria’s North and Murray Water Resource Plan, a summary of the methods used to determine sustainable diversion limits and take is in Chapter 9 (PDF, 442.8 KB), supported by further information in Appendix C (PDF, 991.0 KB).
VIC 3.7: Victoria works closely with other members of the National Hydrology and Modelling Partnership to implement eWater Source
