Water systems remain largely invisible – until something goes wrong. When it does, the consequences can be costly, disruptive and slow to diagnose. Rosendahl and MacMillan zero in on a compelling premise: what you can’t see, you can’t manage, and in the case of water, that lack of visibility is costing facilities thousands of dollars each year. From delayed utility data to hidden leaks behind walls or underground, the speakers illustrate how traditional approaches leave teams reacting to problems long after they begin.
