WaterGroup Pty Ltd announces the release of Sebalog N-3, Australia’s first permanent leak detection network that correlates network noise loggers. The leak detection system was first installed for the Wingecarribee Shire Council.

Monitoring trunk mains in remote areas is a costly process, primarily due to the amount of time needed to access the site before leak inspection can begin. Additionally, the large diameters of trunk mains represent a problem for many conventional acoustic leak detection systems.

However, trunk mains also need to be continuously monitored as leaks on such pipes could lead to significant water losses, and even pipe bursts.

SebaKMT’s fixed network of correlating noise loggers enables both remote monitoring of trunk mains and exact location of leaks, even on large diameter pipes.

Key features and advantages of Sebalog N-3 leak detection network include remote leak monitoring and pinpointing; transmission of acoustic recordings for correlation; advanced web-based evaluation software; adaptability to existing SCADA systems; and cascading repeater functionality.

Sebalog N-3 leak detection system was installed for Wingecarribee Shire Council to monitor a 14km long trunkline, with several leaks identified by the N3 system within months of the installation. The leaks were later verified in the field, saving the community a lot of water, and money.
