Leak Detection Tucson: The Same Chapter Pays You and Fines You
Every city in this series has an answer to what it owes a household with a leak. Tucson has two answers, they sit in the same chapter of the city code, and they point in opposite directions.
One route offers an adjustment on a bill inflated by a leak. The other makes failing to repair a controllable leak a prohibited use of water, a civil infraction carrying a minimum fine, enforced by inspectors who both respond to reports and look for evidence while out on the streets.
Which of the two a household meets is not decided by the leak. It is decided by what happened after somebody knew about it, which makes leak detection Tucson work an evidential exercise as much as a technical one.

Two Customers With the Same Leak Get Two Different Formulas
Start with the money, because it is the part that surprises people even when they knew an adjustment existed.
Tucson Water offers adjustments on request where there is valid high water use because of leaks, theft, vandalism or another known consumption, and also where there is unexplained high use. Four conditions all have to be met. Use must have returned to normal levels. The use in question must have been more than twenty CCF. No adjustment can have been given on the account within the past three years. And the use must have occurred within the past seven months. No adjustments are available at all on reclaimed water or construction water accounts.
So far, so much like other cities. What is genuinely unusual is that the arithmetic then splits by who you are.
A Customer Relief Adjustment is calculated by charging a residential customer for the high water use at the current adopted rate for the same water use block of the same month of the prior year. It applies to the residential single family and duplex-triplex customer classes. In plain terms, the excess is re-priced as though it had been last year, in the tier the household was sitting in during the same month.
A Courtesy Adjustment is calculated by taking the difference in water use between the high month and the same month in the previous year, and allowing one half of that amount to be dismissed. It applies to multifamily, mobile home parks with sub-meters, commercial and industrial customers. In plain terms, half the excess goes away and the rest is charged as normal.
Those are not two names for one thing. One remedy attacks the price of the water, and it depends on where the customer sat in the rate structure a year earlier. The other attacks the quantity, and it does not care about tiers at all. A landlord and their tenant, on the same street, with the same failed fitting, are on different formulas because of what the buildings are.
All other applicable water charges and taxes are applied after the adjustment, so the relief is calculated first and the extras follow it.
Who Has to Prove What, and Which Way the Presumption Runs
Six published positions on the same subject, sorted by who carries the burden. Read as a set they say something the city never says in one place: in Tucson, a leak is a matter of evidence before it is a matter of plumbing.
The adjustment: you prove it ended
An adjustment requires that water use by the customer has returned to normal levels. The proof of the repair is the return of the meter to ordinary readings, so the sequence is fix first and ask second.
The adjustment: you prove it was recent and rare
The use must have occurred within the past seven months, must have exceeded twenty CCF, and no adjustment can have been given on the account in the past three years. Three separate tests, all of them dated.
The ordinance: the account holder is presumed to know
The water waste section states that the person or organisation in whose name the utility was last billed, or who is receiving the benefit of the supply, is presumed to have knowingly made, caused, used or permitted the use, if water has been used contrary to the section.
The ordinance: more than one person can be cited
The city states that depending on circumstances the ordinance also allows a property manager or landscape contractor to be cited for water waste in addition to the property owner.
Tampering: the burden switches to you
It is illegal to tamper with or bypass a water meter, and the city states that an amendment to the code on bypassing metering places the burden of proof on the customer where the meter has been tampered with.
The free investigation: you go first
Tucson Water states plainly that it cannot locate leaks on private property, and asks the customer to work through the published visual leak steps before a representative will submit a high bill investigation request.
An Unrepaired Leak Is a Civil Infraction, and It Has Been Since 1984
The water waste ordinance opens with a policy statement rather than a rule: because safe, high quality potable water matters, the general welfare requires that the water resources available to the city be put to maximum beneficial use, and that waste or unreasonable use, or an unreasonable method of use, be prevented.
Then it lists six prohibited uses, and the sixth is the one that turns a plumbing problem into a legal one. Failing to repair a controllable leak, including a broken sprinkler head, a leaking valve or a leaking faucet.
Note the word controllable. The clause is not about a catastrophic failure or a hidden loss under a slab that nobody could reasonably know about. It is about the leak somebody could have stopped and did not, which is precisely the category that survives for months because it is small enough to tolerate.
The penalty is a civil infraction with a minimum fine of $250 on a first offence, and a minimum of $500 on a second offence within three years and on each subsequent conviction in that period. Civil liability does not preclude the city from taking other enforcement action available to it under the same chapter.
Enforcement is real and it is not purely reactive. Tucson Water employs conservation inspectors who investigate reported cases of water waste, and who also look for evidence of water waste while out on the streets. A warning is usually issued for a first-time violation, with information on how to correct the problem, and a citation is written if the problem is not corrected. The city describes the goal as educational even after a citation has been issued.
Two details in the section deserve attention from anyone who does not own the property they occupy or manage. The presumption clause attaches to the person or organisation in whose name the utility is or was last billed, or who is receiving the benefit of the water supply on the premises, and presumes that they knowingly permitted a use contrary to the section. And the city states that depending on circumstances a property manager or a landscape contractor can be cited in addition to the property owner.
Reporting routes are published as well, which is worth knowing in both directions. Water waste can be reported by email, by voicemail on a dedicated number, and through the city service request application. A running leak on a wall in a car park is somebody else's report waiting to happen.
The Utility Will Check Its Meter for You, After You Have Done Your Half
Between the credit and the fine sits a free service, and its sequence is the interesting part.
Tucson Water publishes a high bill and usage alert page that begins with an honest limitation: it states plainly that it cannot locate leaks on private property. It then points the customer at a published guide of visual leak steps and asks that those be worked through first.
Once they have been, a Utility Service Representative can submit a High Bill Investigation work request to ensure there is not a leak at the meter. During the visit, the utility verifies the meter number, checks for continuous flow, visually inspects the meter, pulls the readings where the meter type allows it, and leaves a report for the customer to review. The report is commonly left in the meter box, at the door or in the mailbox. The service is free and can be requested by form or by telephone.
Three things follow from reading that carefully.
First, the visit is bounded at the meter. It is a check of the utility side and the connection, not a survey of your plumbing, and expecting more from it will waste a week. Second, it produces a document, and a document dated before a repair is a useful thing to have when an adjustment request later has to show that use has returned to normal. Third, the sequence rewards households that can demonstrate they did something. The city asks for your half first, and the ordinance presumes you knew.
WHAT THIS PAGE IS NOT GOING TO DO IS TELL YOU HOW TO READ YOUR OWN METER. The published test that a householder can run at a meter is set out in full on our national leak detection page, and it is the same test everywhere. What is specific to Tucson is that the utility will come and do its own version of that check for nothing, once you have done yours, and will leave the result in writing.
What to look for in the meantime, in the house rather than at the meter, is covered in our guide to the signs of a hidden water leak. On a slab city with no basement to inspect, those signs are doing more work than they would elsewhere, and the reason why is set out on the main Tucson page.
Nobody Agrees on What a Utility Owes a Household With a Leak
This series has now read the published leak position of eight separate utilities, and there is no common answer. Not a common figure, not a common clock, not even a common kind of remedy. The table is a summary; each city page carries its own version in full.
| Utility | What it does about a leak on your bill |
|---|---|
| Phoenix | Adjusts the sewer charge through a review that closes on a published deadline. |
| San Diego | Adjusts the water bill, on a clock, with a published exclusion list. |
| Los Angeles | Adjusts both, at two different departments with two different clocks on one printed bill. |
| Sacramento | Adjusts neither and reimburses the repair instead, once per customer. |
| Atlanta | Sends a contractor and pays the contractor, with a non-profit deciding the scope. |
| Denver | Refuses inside leaks on a physical argument: the water entered the sewer and had to be treated. |
| Chicago | Refuses everything, stating it is required by ordinance to bill for all usage registered on the meter. |
| Tucson | Two different formulas depending on customer class, on four conditions, once every three years. And a separate section of the same chapter under which an unrepaired controllable leak is a fineable civil infraction. |
Two things are worth taking from the spread. The first is that advice travels badly. A plumber, a landlord or a property manager who learned the rules in one of these cities will be confidently wrong in most of the others, and the error is always in the same direction, which is assuming a remedy exists.
The second is that Tucson is the only one of the eight where the same body of law that offers the remedy also contains a penalty for the same underlying facts. That is not a contradiction. It is a policy about time: the credit is for the loss you stopped, and the fine is for the loss you did not.
What to Do With a High Bill in Tucson, in the Order the Rules Reward
The order matters more here than in most cities, because one route requires that the problem has already ended and the other is triggered by the problem continuing.
- Read the alert on the bill rather than the total
The city issues a high usage alert on the statement. It is the earliest dated evidence you will have that something changed, and it starts the clock you will later have to prove you were inside.
- Work through the published visual steps first
The utility asks for this before it will raise an investigation, and it says openly that it cannot locate leaks on private property. Doing your half is a precondition rather than a courtesy.
- Ask for the free high bill investigation
It checks the meter number, looks for continuous flow, inspects the meter and pulls readings where the meter type allows, and it leaves a written report. Free, and documentary.
- Fix the controllable things immediately, whatever else is unresolved
A running cistern, a dripping valve, a broken sprinkler head. These are the named examples in the ordinance, and leaving them while a bigger investigation proceeds is the exact fact pattern the water waste section describes.
- Locate what is not visible
On slab construction the loss may be under concrete, and the location work that precedes opening a floor is set out on the main Tucson page. The point for this page is that the adjustment route needs the loss to have stopped.
- Let the meter return to normal, then ask
The first eligibility condition is that use has returned to normal levels. Requesting before that is asking to be refused on a technicality that a fortnight would have cured.
- Check the three year and seven month windows before you spend effort
No adjustment within the past three years on the account, and the use within the past seven months. Both are simple facts to establish, and either can end the question.
Six Questions That Decide Whether an Adjustment Is Even Available
- Has usage returned to normal?The first published condition. It makes the repair a precondition of the remedy rather than a consequence of it.
- Was the excess more than twenty CCF?Below that threshold the published conditions are not met, however annoying the bill.
- Has this account had an adjustment in the last three years?One in three years is the published limit, which makes a small claim now potentially expensive later.
- Did the use occur within the past seven months?Older than that and the condition is not met. Bills that were queried and forgotten are the usual casualty.
- Is this a reclaimed water or construction water account?The city states no adjustments are available on either, without qualification.
- Which customer class is the property in?Single family and duplex-triplex get the relief calculation. Multifamily, mobile home parks with sub-meters, commercial and industrial get the courtesy calculation. Same leak, different arithmetic.
Leak Detection Tucson Questions, Answered Straight
The two adjustment formulas, the conditions, the ordinance and the free meter check.
It offers adjustments on request where there is valid high use because of leaks, theft, vandalism or another known consumption, and where use is unexplained. Four conditions must all be met: use has returned to normal, the use exceeded twenty CCF, no adjustment has been given on the account in three years, and the use occurred within the past seven months.
It depends on the customer class. A Customer Relief Adjustment charges a residential single family or duplex-triplex customer for the high use at the current adopted rate for the same water use block of the same month of the prior year. A Courtesy Adjustment, for multifamily, mobile home parks with sub-meters, commercial and industrial, dismisses half the difference between the high month and the same month a year earlier.
Yes. The city states that no adjustments are made available for reclaimed water or construction water accounts. That is stated without qualification, so those account types sit outside the scheme entirely.
For failing to repair a controllable leak, yes. It is one of six prohibited uses under the water waste ordinance, which has applied since 1984, and the named examples are a broken sprinkler head, a leaking valve and a leaking faucet. It is a civil infraction with a minimum fine of $250, and a minimum of $500 for a second offence within three years.
It has inspectors for it. Tucson Water employs conservation inspectors who investigate reported cases and who also look for evidence of water waste while out on the streets. A warning is usually issued first, with information on how to correct the problem, and a citation is written if the problem is not corrected.
It can. The section presumes that the person or organisation in whose name the utility was last billed, or who is receiving the benefit of the water supply on the premises, knowingly permitted a prohibited use. The city also states that depending on circumstances a property manager or landscape contractor can be cited in addition to the property owner.
The city states it is illegal to tamper with or bypass water meters, that the ordinance regulates illegal hose or meter tie-ins, and that a code amendment on bypassing metering places the burden of proof on the customer where the meter has been tampered with. Violators face the same minimum fine.
Not on your property. Tucson Water states that it cannot locate leaks on private property. It will, free of charge, submit a high bill investigation to check there is not a leak at the meter, after the customer has worked through the published visual leak steps.
The utility verifies the meter number, checks for continuous flow, visually inspects the meter, pulls the readings where the meter type allows, and leaves a report for the customer to review, commonly in the meter box, at the door or in the mailbox.
Deliberately not covered here. One page in this series works through what a city does and does not do about pool losses in real detail, and duplicating it would add nothing. The link sits in the sources note at the end of this page.
Stop the Loss First, Because Both City Routes Depend on It
The alert on the bill treated as dated evidence, the visual steps done before the utility is asked, the free meter investigation requested and its written report kept, every controllable leak repaired immediately whatever else is still being traced, and the adjustment asked for only once usage has genuinely returned to normal. Tell us the cross streets and what the bill did.
Sources, and What We Deliberately Left Out
The adjustment conditions, the twenty CCF threshold, the three year and seven month windows, the reclaimed and construction water exclusion, both calculation methods and the customer classes they apply to, and the note that other charges and taxes are applied after the adjustment, all come from the Tucson Water bill adjustments page, which cites Tucson City Code Part II, Chapter 27, Section 27-52.
The six prohibited uses, the controllable leak clause, the fine levels, the presumption clause, the conservation inspectors, the warning-then-citation practice, the property manager and landscape contractor provision and the meter tampering burden of proof come from the city water waste page and from the published text of Tucson Code 27-15 alongside it.
The statement that the utility cannot locate leaks on private property, the required order of the visual steps, and the contents of the free high bill investigation come from the Tucson Water high bill and usage alert page.
WHAT WE REFUSED TO WRITE, AND IT WAS THE OBVIOUS THING. This page does not tell you how to read your own water meter to check for a leak, even though the city's own free visit checks the meter for continuous flow and the method is one sentence away in the source. That test is set out in full on our national leak detection page and it is the same in every city. What is local is the utility's free version of it and the written report it leaves behind, and that is what is described above.
Also refused: swimming pool losses, in every form, despite a real share of local demand asking about them. Our San Diego leak detection page works through what a city will and will not do about a pool and answers it honestly, and a second version would be a copy. The rainwater harvesting requirement referenced inside the water waste ordinance is also left out, because it is a landscape irrigation obligation with its own document and naming a clause without reading it would misdescribe something a person can be fined under.
Deliberately not covered because other pages own them. Hardness, slab construction, caliche, pressure zones, meter isolation, acoustic and thermal location and the economics of a repipe all sit on the Tucson city page. The detection methods themselves sit on our national leak detection page. The private service line protection product that the City of Tucson lists in its own site navigation is refused here as it has been across this series.
