Meter it for a month. Find out where the water goes.
NES clamps ultrasonic meters onto your existing water lines and reads them for as long as you need. Nothing is cut, nothing is shut off, and the building keeps running. You get real numbers on what each line uses, and a call the day one of them runs when it should be still.
What is temporary water verification and auditing?
It is a short-term audit of the water lines in your building. NES clamps ultrasonic meters onto the pipe you already have, with no cutting and no shutoff, and reads them for a set period. At the end you know what each line actually used, hour by hour, and NES calls you along the way any time a line runs when it should read close to zero. Hotels, high-rise buildings, stadiums, and arenas use it to settle usage questions and to find leaks that never turn up on a walkthrough.
- Ultrasonic clamp-on meters install without cutting pipes or shutting off water
- Temporary by design: run it a week, a month, or longer
- Metered by line, riser, wing, or zone, whichever answers your question
- Catches stuck flush valves, running toilets, and line leaks
- You get the readings, not just a verdict
- Installed and read in house by NES since 1968
One number a month, for a building with a thousand fixtures.
A hotel, a high-rise, and an arena all get the same thing from the utility: one total, weeks after the water went through the pipe. It does not tell you which riser, which wing, or which restroom bank. So when the number jumps, the answer is a guess, and when a flush valve sticks open on a quiet floor, nobody is standing next to it. One stuck valve can waste thousands of gallons a day, and a big building has hundreds of them. A temporary audit replaces the guess with a reading: meters go on the lines in question, they run for a set period, and the building tells you where the water goes.
We clamp on, we read, and you get the numbers.
- 1
We clamp on, not cut in
The meters strap onto the outside of your existing pipe and read the flow with ultrasound. No pipe is cut, no water is shut off, and the building keeps running while we install.
- 2
Every line learns its normal
Risers, wings, restroom banks, laundry, cooling, and irrigation each get a picture of what flow should look like at every hour. Overnight should read close to nothing.
- 3
Odd flow gets a call
When a line runs while it should be still, or well above its normal, NES calls your engineering and maintenance staff the same day, with the line and the size of the problem.

You get the audit
At the end of the period you get the readings for every metered line, what each one used, and what NES found. Leave the meters on, move them to the next set of lines, or take them off.
The reason most buildings never meter their lines: they think it means shutting the water off.
You cannot cut into a live line that feeds a thousand fixtures in an occupied building, and you should not have to. An ultrasonic clamp-on meter reads the flow from the outside of the pipe, so there is nothing to cut, nothing to drain, and no reason to close a restroom or empty a floor. Most meters go on in under an hour, and the work happens while the building keeps running. It works on the metal and plastic pipe already in your walls.
- No pipe cutting and no shutoff to install
- Reads flow from outside the pipe with ultrasound
- Goes on live lines while the building operates as normal
- Fits the metal or plastic pipe you already have
- Comes back off when the audit is done, or stays on if you want it
- Installed and read in house by NES, not a subcontractor
Most metering vendors sell you a device. NES runs the whole thing.
Buy a meter and a dashboard from a hardware vendor, and the install, the tuning, the reading, and the 3 a.m. phone call are still your team’s job. NES puts the meters on, sets the normal for every line, reads the flow for as long as the audit runs, and calls your engineering staff when a line runs wrong. One company, one phone number, and a team that has done this since 1968.
The leaks that hide in a big building.
Stuck flush valves
A flushometer that hangs open can run thousands of gallons a day, and a large building has hundreds of them.
Running toilets
The worn flapper nobody reports. On its own it is small, but it never stops, and there are a lot of them.
Line and pinhole leaks
A crack behind a wall or under a slab that never shows up out front until the damage does.
Irrigation left on
A landscape or field zone that keeps watering after the valve should have closed.
Cooling-tower make-up
A float or fill valve on the mechanical side that keeps topping off long past full.
Any after-hours flow
Water moving through a line at 3 a.m., when the reading should be close to zero.
Your team hears about it the same day, not on next month’s bill.
When a line runs while it should be still, NES sends your engineering and operations staff a short, plain message. Here is what one looks like for a sample building.
Any building with more fixtures than anyone can watch by hand.
Hotels and resorts, commercial and residential high-rise buildings, stadiums, and arenas all run into the same problem: hundreds of fixtures, a small crew, and a water bill that only tells you about the leak weeks after it started. A temporary clamp-on audit puts a meter on the lines that matter, reads them for a set period, and shows you the flow you have been paying for without knowing it.
