If I had $100 for every time I said that, I'd be a millionaire.
That is what a water conservation coordinator at a utility told us on a recent call. Here is what she was saying: the utility is not responsible for leaks, breaks, or issues on the customer side of the meter.
She says it constantly. Anything past the meter belongs to the owner.
Where the Utility's View Ends
The utility's responsibility ends at the meter, and so does its visibility. The utility can see the meter. What happens behind it is the owner's to find.
Dan Prescott explained it with a 300-unit multifamily property on a four-inch or six-inch main line. The utility's meter sits on that main, and its data does give visibility into the property. But the owner does not know what is happening behind the main. If there is a problem in the water, they do not know where it is.
What the Utility Can See, and What It Can't Say
The utility team described how this plays out. When a customer uses 1,400 gallons in an hour, an alert comes in and the utility calls the customer. But the utility does not know where the water is going. The customer walks the property, and the answer is usually, "Look at your property. Oh, well, I don't see anything." Sometimes the leak surfaces. Sometimes it doesn't.
When a customer is told they are running 200 gallons an hour, the response is that their house would be flooded if that were the case, and there is no water running. Dan added that the call that follows is the one when the bill arrives, and the customer says there is no way.
The coordinator's own summary was that the utility's data gives one data point on the main meter. Knowing something is wrong is different from knowing where.
A Leak Nobody Goes Looking For
Dan described the cost side with an example. A larger commercial user's bill is uncapped. Picture a valve in the back corner of the property that nobody goes to very often. If it is wide open, it can run 1,000 gallons an hour, and if no one is back there, there is no way to know.
In a 300-unit building, that can become noise. The property manager might say, "Yeah, it's hot outside."
Dan said the visibility often pays for itself. Not always, but often, because the customer catches the problem early and does not have to go to the utility for leak forgiveness.
Putting Eyes on Your Side of the Meter
If the utility is not responsible past its meter, the owner is the one who needs eyes on what is back there. Dan's answer on how that works was that the engineering study, and any additional meters or devices, are something the customer buys and installs.
PhantomH2O's engineers look at the plumbing and water schematics and recommend three or five points to monitor. No two buildings are the same, so the points are not the same either. They can also instrument things like a cooling tower, monitor its consumption, and help the customer right-size the cooling so water is not wasted.
The difference is what the owner sees. Instead of saying, "I've got a problem somewhere in my building," they see which area's use went up. Three to five well chosen points can turn "a problem somewhere" into "a problem here."
