Throughout the fiscal year July 2019 to June 2020 the City of Logan just outside of Brisbane on Australia’s East Coast found and repaired a total of 154 water main leaks, breaks, and bursts throughout their 2293 km water system – a result of 145 leak detection surveys with ZONESCAN 820 Lift & Shift loggers. In May of 2021, following their success with ZONESCAN 820, the City of Logan decided to implement a 300-point ZONESCAN NB-IoT logger system.
The new system was an immediate success. After only a few months, Logan Water found 13 service/main leaks and 10 customer-side leaks, amounting to roughly 490 cubic meters of actual non-revenue water (NRW) loss. Totaled, the stoppage of these leaks prevented an estimated $261,000 USD in NRW over a 12 month period. A new case study details two non-surfacing leaks identified by Logan’s NB-IoT system in July, 2021. These two leaks alone were estimated to incur losses of $182,000 in NRW annually.
