City of Phoenix Water Services
How do I spot a leak on a City of Phoenix water bill?
On a City of Phoenix Water Services bill, the line to read for a leak is the Monthly Water Usage History chart rather than the amount due, because Phoenix prints thirteen months of usage in gallons and a leak shows there as a step that never comes back down. Phoenix bills water, sewer and solid waste together on one City Services Bill, so the total moves for reasons that have nothing to do with water.
Reading the bill
One statement, three services
A Phoenix City Services Bill carries water, sewer and solid waste charges on a single monthly statement.
Because three services share one statement, comparing one month's total against another is a poor way to look for a leak. The water usage figure is the part that responds to a leak; the rest of the bill does not.
Phoenix measures water in units and also prints the equivalent in gallons, and the bill states the conversion on its face: one unit is 748 gallons. That matters when you compare notes with somebody in another Valley city, because not every provider uses the same unit.
The bill carries a Monthly Water Usage History chart in gallons covering thirteen months, set against the same months of the previous year. That side-by-side is the most useful leak-detection tool most Phoenix households already have, and the same information is in the online ePortal account.
The cycle
Monthly, and not a calendar month
Phoenix reads monthly, and the billing period runs between meter reads rather than from the first of the month to the last. A leak that starts mid-period therefore lands half-shown on one bill and fully shown on the next, which is why a second bill that is worse than the first means the loss is still running.
The meter
Where to look, and what to watch
On most Phoenix lots the meter sits in a box in the ground near the footpath, and on some older streets in the alley behind the property. The lid usually needs a screwdriver or a meter key. Look into the box before reaching into it.
With every fixture, the irrigation controller and the pool equipment switched off, watch the low-flow indicator on the meter face - the small dial, triangle or star that turns at the slightest flow. Movement means water is leaving on your side of the meter. Write the full reading down, photograph it, and read it again an hour later.
In the usage history
What the thirteen-month chart is telling you
| What the chart shows | What it suggests | What to check |
|---|---|---|
| A step up that never returns to the old floor | A continuous loss that started then | The meter, with everything switched off |
| A smooth summer peak matching last year's | Irrigation and the pool answering the heat | Nothing on the bill; compare the same months, not adjacent ones |
| One tall month, then back to normal | A one-off: a pool fill, guests, a new planting | Whether anything happened that month |
What they publish
The sewer charge, and the review Phoenix publishes
Phoenix calculates the residential sewer fee from water use during the winter months, when outdoor watering is at its lowest, and applies that figure for the year. The practical consequence is that a leak running in January, February or March follows you through the sewer portion of the bill long after it has been repaired.
Phoenix publishes a Sewer Fee Review process through myPHX311 for customers whose winter usage was affected, and its own wording covers spikes in water use caused by broken plumbing. It reviews the sewer portion, not the water portion, and it has a submission window tied to the July bill. We found no published policy for adjusting the water portion of a Phoenix bill.
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
Phoenix billing questions
Which line on a Phoenix water bill shows a leak?
The Monthly Water Usage History chart, which shows thirteen months of usage in gallons against the same months of the previous year. A leak appears there as a step up that never returns to the previous floor, rather than as a single tall bar.
Why is my Phoenix sewer charge high when my water use has come down?
Because Phoenix works the residential sewer fee out from winter water use and applies that figure across the year. A leak that ran during the winter months is carried in the sewer portion long after the water use itself returned to normal.
Does the City of Phoenix adjust a bill after a leak is repaired?
Phoenix publishes a Sewer Fee Review process through myPHX311 which covers winter usage affected by broken plumbing, and it reviews the sewer portion rather than the water portion. We found no published water-bill leak adjustment. Ask Phoenix what applies to your account.
What is a unit on a Phoenix water bill?
Phoenix states the conversion on the bill itself: one unit is 748 gallons. The bill shows usage both ways, which is worth knowing before comparing your figures with somebody billed by a different Valley provider.
