Melbourne Water has completed its most extensive connected metering program to date, bringing real-time telemetry to every surface water diversion meter across its river catchments. The project covers the Yarra River and the lower Maribyrnong, giving more than 1,300 licence holders continuous visibility into their own extraction volumes while enabling the utility to monitor compliance across its network without manual meter reads.
From Manual Reads to Continuous Monitoring
Until this rollout, surface water diversion monitoring in Melbourne Water’s catchments depended substantially on periodic manual readings, a method that limits both operational responsiveness and the regularity of compliance checks. The completed upgrade replaces that model with continuous, automated data transmission. Water extraction volumes across the two catchments can now be tracked in real time, with licence holders also gaining direct access to their own consumption data through the telemetry system.
The program was delivered in collaboration with Sage Automation, an Australian industrial automation and control systems integrator with more than 25 years of experience in the water sector, and Kallipr, a specialist in IoT-based water monitoring and telemetry device technology. Kallipr’s Captis edge-gateway platform has been deployed in several non-urban metering programs across Australia, including NSW compliance rollouts and projects under the federal Telemetry Uplift Program.
Enforcement Framework Accompanies the Infrastructure Upgrade
Alongside the technical rollout, Melbourne Water has introduced formal enforcement mechanisms to protect the integrity of the new metering infrastructure. Penalty infringement notices are now enforceable under Section 288 of the Water Act 1989 against anyone who tampers with or interferes with a diversion meter or associated telemetry equipment without authorisation. The penalties came into effect on December 17, 2025, with individuals subject to fines of up to AUD 2,442 and body corporates facing penalties of up to AUD 12,211.
The introduction of these penalties reflects the broader view that metering infrastructure interference does not only raise legal issues but carries practical consequences: disrupting accurate allocation data can affect other licence holders and increase the cost of maintaining the monitoring network.
Alignment with Victoria’s Non-Urban Metering Policy
The Melbourne Water rollout is directly tied to obligations under Victoria’s Non-Urban Water Metering Policy, which set a statewide target for all metered water take to be telemetered by June 2025, where benefits outweigh costs. Victoria has built one of Australia’s largest fleets of modern non-urban meters over the past two decades, with the state reporting 49,073 non-urban water meters as of June 2025. The Melbourne Water project represents a distinct component of this statewide push, focused specifically on the regulated surface water diversion licences within its geographic catchments.
The policy itself traces back to commitments under the Murray-Darling Basin Compliance Compact, signed in 2018 following scrutiny of water management transparency across basin states. Melbourne Water’s surface catchments sit outside the Murray-Darling Basin proper, but the regulatory framework and its emphasis on telemetry as a compliance tool shapes how all Victorian water corporations approach metering reform.
What Real-Time Visibility Changes for Licence Holders
For the more than 1,300 water users connected to Melbourne Water’s surface water network, the shift to real-time telemetry changes the information available to them on a daily basis. Previously, licence holders had limited immediate feedback on their cumulative draw. With continuous data now accessible, they can track extraction in relation to their licence entitlements in real time, supporting better operational decisions, particularly during low-flow periods when allocation conditions tighten.
The broader metropolitan Melbourne region has seen significant parallel investment in digital metering for urban supply networks. Kurrant has reported on Yarra Valley Water’s deployment of approximately one million NB-IoT connected devices across its northern and eastern Melbourne network, and on South East Water’s AUD 87 million, 10-year contract with TPG Telecom to deploy one million NB-IoT smart meters across its supply area. While those projects target residential and commercial metering within pressurised pipe networks, Melbourne Water’s rollout addresses a structurally different challenge: unregulated surface diversion monitoring across open catchments and river channels.
Further Rollout Planned
Melbourne Water has indicated the telemetry program will continue beyond this phase, with further meter upgrades planned across the region. The utility’s Non-Urban Water Metering Action Plan, published in 2025, outlines ongoing commitments to metering compliance and telemetry expansion as part of a longer-term trajectory toward automated, accurate reporting of all water take within its jurisdiction.
The completion of this phase establishes a baseline of continuous data across the Yarra and lower Maribyrnong catchments that will underpin both routine compliance and longer-term water resource planning as the region faces growing pressure from population growth and variable rainfall patterns.
