City Of North Bay Uses Condition Assessment On Critical Force Main To Implement Asset Management Plan
On one hand, it may seem like a waste of capital dollars if you perform a pipeline condition assessment and the final analysis turns up no leaks. Alternatively, you can also look at the no-leak report as a good news validation story, especially when using the information to help establish an asset management plan. Such was the case for a city of 51,000 situated between the shores of lovely Lake ...

Counting the Drops: Leak Detection and Auditing Methods for Property Managers
Leaks are never good, whether it’s a leaky boat or a leaky pipe system. Even advanced water utility systems can experience water loses ranging from 10 – 40%, with these losses being proportional to the population of the urban area serviced by the water distribution system. Large cities like New York, Chicago, and Los Angeles are vulnerable to staggering amounts of water loss in ...

Tackling Non-Revenue Water by Identifying Small Leaks
Small leaks sink big ships – the same can be said for large-diameter pipes in utility networks. While large leaks or ruptures are seen as newsworthy stories accompanied by images of water flowing down the streets; smaller leaks can often be more devastating. Left undetected, they can add up over time, contributing significantly to Non-Revenue Water, and eventually, they too can lead to ...
