Tonga utility selects Itron smart water solution

Tonga Water Board will take advantage of the existing OpenWay Riva network utilised by Tonga Power Limited

Tonga takes another step towards becoming a smart island

Tonga Water Board is upgrading its distribution system to help reduce water losses, optimise operations and improve revenue as part of a smart island project.


The Kingdom of Tonga’s government-owned water utility has signed a contract with Itron to use its OpenWay Riva Internet of Things (IoT) network and managed services.


Building on the Kingdom’s success with its electricity system, the utility will use the same network and new smart water meters to reduce water losses associated with leaks, capture lost revenue due to non-payment and improve customer service.


Tonga Water Board will take advantage of the existing OpenWay Riva network utilised by Tonga Power Limited (TPL) on Tonga’s main island of Tongatapu to connect with OpenWay Riva-enabled static water meters.


In collaboration with TPL, the utility will also make use of Itron managed services for network management and maintenance for water operations.


“By utilising the existing OpenWay Riva network on Tongatapu island for water, we are becoming a truly smart island,” said Aisake Tuiono, chairman of the smart metering committee for the Common Utilities Board.


“We look forward to extending the benefits of an open standards network to our water operations so we can better account for water losses while improving service and reliability for our customers.”


A combination of old infrastructure, inaccurate consumption measurement and unpaid invoices has resulted in high levels of non-revenue water losses in some areas of Tongatapu island, reducing the utility’s revenue intake.


With the collection and analysis of more detailed data over the network, Tonga Water Board can measure water consumption more accurately, detect leaks faster and empower its customers to monitor their consumption on a continuous basis.


“Through a comprehensive resource management program that addresses challenges in energy, water and smart communities, Tonga is showing that it is both smart and connected,” said Paul Nelsen, vice president for electricity in the Asia-Pacific, Itron.


“Itron is excited to be a part of this visionary smart island project, which will demonstrate how technology can help utilities better manage water and electricity resources and create a more resourceful world,” added Dominique Lerouge, vice president for water and heat in the Asia-Pacific, Itron.
