How do I check for a leak as a City of Mesa water customer?
Mesa publishes something most Valley providers do not: a page that explains how to read your own utility meter and identify a leak on it, including what the different makes of smart meter do when they are showing a flow rate. That makes the meter, rather than the bill, the natural place for a Mesa customer to start.
Reading the bill
Start at the meter, not the statement
Mesa publishes its own guidance on reading a utility meter and identifying a leak from it.
Read the unit of measure printed on your own Mesa statement before you compare your usage with anybody else's, because Valley providers do not all bill in the same unit and the comparison is meaningless without it.
What the statement is genuinely good for is the shape of usage over time rather than the total at the bottom. A leak raises the amount used in every period and keeps it raised, so it is the lowest bars in a history that give it away.
The cycle
Read your own billing period
Billing periods run between meter reads rather than from the first of a month to the last, so a leak beginning mid-period is understated on the first bill and fully reflected on the second. Two consecutive statements tell you more than one.
The meter
What Mesa's own meter guidance covers
Mesa's page covers the classic test first: turn off everything that uses water and see whether the meter still registers flow. That works on any meter, old or new.
For smart meters, Mesa names the behaviour by make, which is unusually practical. A Neptune meter displays the current flow rate briefly during its read cycle. A Badger meter shows the flow rate after the billing read has cycled through. A Sensus meter has a dedicated flow-rate screen. Knowing which make is in your box saves standing over it waiting for the wrong thing.
What a leak looks like
Reading the meter and the history together
| What you observe | What it suggests | What to do next |
|---|---|---|
| Flow registering with everything switched off | A loss on your side of the meter | Isolate the irrigation and read again |
| Usage up in every period since a particular month | A continuous loss from that month | The meter test, then toilets and the pool auto-fill |
| Flow only when the irrigation is scheduled | The irrigation system | Run each zone and walk the run |
What they publish
What Mesa publishes about the wastewater fee
Mesa publishes a Request for Residential Wastewater Fee Adjustment form, which is concerned with the wastewater portion of the bill and with leaks repaired during the winter months of December through March. Mesa's form also notes that accounts served by Arizona Water Company do not qualify, because some parcels in the Mesa area are served by a separate private water company rather than by the City.
Which water provider actually serves your street is a question your own bill answers and we will not guess at. It matters here, because it decides which set of rules applies to you.
Billing questions are between you and your provider, and what they do about them is theirs to decide. Our part is establishing whether the property is losing water and where, in writing.
Straight answers
Mesa billing questions
How do I read a Mesa water meter for a leak?
Turn off everything that uses water, then watch whether the meter still registers flow. Mesa publishes guidance on this, including what each make of smart meter does: Neptune shows the flow rate briefly during its read cycle, Badger shows it after the billing read, and Sensus has a dedicated flow-rate screen.
Does Mesa adjust a bill after a leak?
Mesa publishes a Request for Residential Wastewater Fee Adjustment form relating to leaks repaired in the December through March winter months, which concerns the wastewater portion. Ask the City what applies to your account.
Why would my Mesa address not be served by the City?
Some parcels in the Mesa area are served by a separate private water company rather than by the City, which Mesa's own adjustment form acknowledges. Your bill is the authority on who supplies your street.
My meter shows flow with everything off. What now?
Water is leaving on your side of the meter. The quickest next move is to close the irrigation shut-off and read the meter again, which separates the yard from the house in one step.

Tell us what the water is doing
What your meter does with everything switched off, and which make of meter is in the box if you can see it.
Photograph the meter face
A photo of the meter with everything off tells us a great deal before we arrive.
