The City of Waterloo relocated the hydrant.AI units in their system into a specific area to determine the ROI on having the units spaced such that the leak locations identified on the map would lead to successfully finding the leaks within the system before digging. The city then confirms the presence of the leak location using correlators prior to digging. Based on just two (2) leaks being found in the area, the city was able to realize an ROI for 2025 on the system in less than 6-months.
King County Water District #90
King County WD #90 installed hydrant.AI units in January 2025. Upon installation the hydrant.AI units immediately detected the presence of a pre-existing leak within the water distribution network and the location recommended for review. As a result, the operations team were able to locate and repair the non-surfacing leak, immediately reducing their nonrevenue water (NRW) and saving money.
Combating Leaks with Innovative Monitoring
By Stan Fong, Ph.D
As Canada’s drinking water infrastructure continues to age, the prevalence of leaks and the challenges that they pose on utilities also increases proportionally.
When it comes to large leaks, there are many effective solutions available for locating these leaks in a system, including traditional leak surveys and correlator technologies, which try to listen for these leaks through the pipe wall or surrounding soil. Smaller leaks, on the other hand, are often too quiet to be captured by these methods.
