NB-IoT Loggers Produce Excellent ROI in Australia
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.
