Hydro Jetting Phoenix: the Machine Is the Easy Part, and This City Regulates Both Ends of the Hose
Everything written about this service is written about the equipment. Pressure, nozzles, what comes off the pipe wall. That is the same in every city and it is covered properly elsewhere on this site.
What is not the same in every city is what a high volume water service is allowed to draw and what it is allowed to leave behind. Phoenix has been under a declared drought stage since June 2022, and that stage explicitly calls for enforcement of the water provisions of its city code. Separately, the city publishes a numbered and closed list of what may enter a storm drain, and nothing a jetting job produces appears on it.
This page is about those two constraints rather than about the machine. What the drought stage actually requires, what the twenty allowable discharges are, how the city goes looking for the ones that are not on the list, and why the honest answer to where the slurry goes is a shorter list than most people assume.
Phoenix Has Been in a Declared Water Alert Since June 2022
This is not a headline about the future of the Colorado River. It is an administrative fact with a date on it, and it has been true continuously for years while almost nobody outside the water department has changed anything about how they behave.
The city adopted a Drought Management Plan in 1990, under Phoenix City Code Chapter 37, Sections 121 through 130.2. In June 2022, with water levels at historic lows at both Lake Mead and Lake Powell, the water services director activated that plan and declared a Stage 1 Water Alert. The city defines Stage 1 as meaning insufficient water supply appears likely.
The plan runs four progressive stages. Stage 1 is Water Alert, Stage 2 is Water Warning, Stage 3 is Water Emergency and Stage 4 is Water Crisis. The director may implement the response procedure and the associated Water Use Reduction Guidelines under Chapter 37 Article X when that is necessary to protect public welfare and safety.
What Stage 1 actually calls for is the part worth reading closely, because it is milder than the name suggests and sharper than most people notice. The city lists two things: public education and conservation programming, and enforcement of water-related provisions in the Water Chapter of the city code. It states elsewhere that city staff direct more resources to enforce all existing codes that impact water use and waste.
So Stage 1 has not banned anything. It has instead turned up the enforcement of rules that already existed, which is a genuinely different proposition from a restriction and is easy to miss precisely because nothing new appeared.
For a service that intentionally puts a large volume of potable water down a pipe, that is the operating environment. Not prohibited, not restricted, but taking place in a city that has formally declared a supply concern and has told its own staff to enforce the water code harder as a result.
Six Destinations, Sorted by Whether the City Has Put Them on the List
This grid does not sort by cost, urgency or equipment. It sorts by where the water ends up, because that is the question Phoenix has actually answered in writing. The city’s position is one sentence long, which is that only stormwater belongs in the storm drain, followed by twenty numbered exceptions.
Landscape irrigation water
On the list, twice over. The city allows landscape irrigation and irrigation water as separate numbered items, and lawn watering as a third. Runoff from watering a garden is not something the stormwater programme is looking for.
Water line flushing
Item one on the city’s own list. A utility flushing a main into the gutter is doing something expressly permitted, which is worth knowing before anybody reports it, and is not the same thing as a contractor emptying a tank.
Washing one car on a driveway
Individual residential car washing is on the list by name. Note the word individual, and note that the city separately says a future stage could ban car washing altogether as a drought measure. Allowed here, and conditional there.
Pool water, but only dechlorinated
The list says dechlorinated swimming pool discharges. The qualifier is doing all the work, and a pool emptied straight to the kerb without that step is not the thing the city said was allowed.
Sewer cleaning slurry
Not on the list. Twenty items, and the mixture of grease, root fragments, sludge and water that a jetting job removes from a line is not any of them. The list is what it is, and absence from it is the answer.
The sanitary sewer instead
A different system with a different regulator, and for a commercial premises a permit question rather than a plumbing one. That is covered on our Phoenix commercial plumbing page, which sets out the discharge permitting regime.
The city also attaches a condition to the whole list rather than to individual items, which is easy to skim past. It states that these non-stormwater discharges are allowable provided they are not a source of significant pollutants. So even a listed discharge stops being listed the moment it is carrying something it should not.
The Programme That Looks
The City Runs a Camera Up the Storm Drain, Not Down It
It is one thing for a city to publish a rule about what may enter a storm drain. It is another to have a programme that goes looking, and Phoenix publishes how that programme works in enough detail to be useful.
The programme consists of outfall inspections, field screening of dry-weather flows, and identifying and eliminating the source of illicit discharges. Staff inspect outfalls for signs of illegal discharge. Where dry-weather flow is observed, meaning water running when there has been no rain to explain it, field screening looks for significant pollutants.
Then comes the step worth knowing about. Inspectors use visual observation, and the city notes that this is sometimes done with closed circuit television equipment, to track the flow up the storm drain line and attempt to identify the source. The camera travels against the flow, upstream, looking for whoever put the water in.
There is a symmetry there that is hard to miss on a page about pipe cleaning. The same department that sends a camera down a sewer to decide whether it needs cleaning also sends one up a storm drain to find out who has been using it as a drain. Both are camera work and both are about accountability for what is inside a pipe.
The city publishes a Stormwater Hotline on 602-256-3190 for questions and for reporting illegal dumping. It is a different number from every other Phoenix number on this site, and it belongs to a part of the water department that most households never encounter.
The Other Destination
There Is No Away in This City, and the City Publishes the Proof
If the storm drain is closed to it, the obvious next thought is the sanitary sewer. That is usually the right answer, and it is worth understanding what it actually means here rather than treating it as disposal.
Phoenix states that it recycles nearly all of its highly treated wastewater, and it names the destinations rather than leaving them vague. Golf courses. Parks. Non-edible crops. The Tres Rios Wetlands. Recharging groundwater aquifers. And cooling at the Palo Verde Nuclear Generating Station.
That last one is the fact that tends to stop people. A share of what leaves the drains of this city goes on to cool a power station in the desert west of it. Whatever else the sewer is in Phoenix, it is not the end of the line.
The practical consequence for a jetting job is modest but real. The contents of a cleared line are entering a system with named customers downstream, which is a reasonable argument for the waste being collected and handled properly rather than being pushed along and forgotten. It is also the reason the city cares what commercial premises discharge, which is a permitting question covered on our Phoenix commercial plumbing page rather than here.
None of this is an argument against jetting a line that needs it. It is an argument for asking a contractor what happens to what comes out, which is a question almost nobody asks and every competent operator can answer.
A Small Structural Oddity
The Drought Plan and the Backflow Rules Share a Chapter
This is a footnote rather than a finding, but it explains something that otherwise reads strangely, so it is worth thirty seconds.
Phoenix City Code Chapter 37 is the Water chapter. The Drought Management Plan sits inside it at Article X, Sections 121 through 130.2. The backflow prevention regime, which governs containment assemblies and annual testing for commercial premises, sits inside the same chapter at Article XII.
That is why the city’s description of what a Stage 1 Water Alert calls for is phrased as enforcement of water-related provisions in the Water Chapter of the city code, rather than as a list of drought rules. A declared drought stage turns up enforcement across a chapter that also contains obligations having nothing to do with drought.
For a household that is a curiosity. For a commercial building it is a practical point, because it means the enforcement posture on a set of obligations you already had can change without any of those obligations changing. The backflow side of Chapter 37 is set out on our Phoenix commercial plumbing page and is not repeated here.
None of which is a reason to jet or not to jet a line. It is a reason to understand that in this city the water code is one document, and a declaration made about one part of it reaches the rest.
What Is Published, What Is Conditional, and What We Are Not Going to Guess
Drought material invites overreach, because the four stage names sound as though they must map onto four lists of rules. The city does not publish that mapping, so the table below separates what it does state from what it says might happen at some unspecified point.
| The question | Status | What the city actually says |
|---|---|---|
| Is Phoenix in a declared drought stage | Stated, with a date | Yes. A Stage 1 Water Alert, declared in June 2022 when Lakes Mead and Powell hit historic lows |
| What does Stage 1 require | Stated | Public education and conservation programming, and enforcement of water-related provisions in the Water Chapter of the city code |
| How many stages are there | Stated | Four. Water Alert, Water Warning, Water Emergency, Water Crisis |
| Which restrictions apply at which stage | NOT PUBLISHED IN WHAT WE READ | The city lists possible restrictions without mapping them to stages, so no mapping is offered here |
| Could restrictions arrive later | Stated as conditional | Restrictions might include watering on certain days and banning outdoor water features. More severe measures may include banning turf irrigation and banning car washing. A drought surcharge could also be imposed |
| May jetting waste go to a storm drain | Answered by absence | The city lists twenty allowable non-stormwater discharges and sewer cleaning waste is not among them |
The fourth row is the important one and it is deliberately blank. Any page that tells you exactly what Stage 2 or Stage 3 would ban in Phoenix is filling in something the city has not published, and on a subject where being wrong would mean telling a business it can carry on doing something it cannot.
Hydro Jetting in Phoenix, Answered From the City’s Water and Stormwater Rules
A declared water alert running since 2022, a closed list of twenty allowable discharges, and the camera the city sends up a storm drain rather than down a sewer.
Not by prohibition. Phoenix has been under a declared Stage 1 Water Alert since June 2022, and the city describes Stage 1 as calling for public education and conservation programming plus enforcement of water-related provisions in the Water Chapter of the city code. Nothing about sewer cleaning is banned or restricted at that stage. What has changed is the enforcement posture on rules that already existed, which is a different thing from a new rule and is easy to miss because nothing visibly appeared.
Not into a storm drain. The city’s stated position is that only stormwater belongs in the storm drain, followed by a numbered list of twenty non-stormwater discharges that are also allowable provided they are not a source of significant pollutants. That list includes water line flushing, landscape irrigation, air conditioning condensation, dechlorinated swimming pool discharges, street wash water and individual residential car washing. Sewer cleaning slurry is not on it, and absence from a closed list is the answer.
It runs a programme designed to. The city describes outfall inspections, field screening of dry-weather flows, and identifying and eliminating the source of illicit discharges. Where flow is running with no rain to explain it, screening looks for significant pollutants. Inspectors then use visual observation, sometimes with closed circuit television equipment, to track the flow up the storm drain line and attempt to identify the source. The published Stormwater Hotline is 602-256-3190.
Stage 1 Water Alert, Stage 2 Water Warning, Stage 3 Water Emergency and Stage 4 Water Crisis. They sit under Phoenix City Code Chapter 37 Article X, in a Drought Management Plan the city adopted in 1990 at Sections 121 through 130.2. The Water Services Department Director may implement the response procedure and the associated Water Use Reduction Guidelines when that is necessary to protect public welfare and safety. The city does not publish a mapping of specific restrictions to specific stages, and we are not going to invent one.
The city describes them as possibilities rather than as a schedule, and it is worth repeating them in that spirit. It says restrictions might include watering on certain days, banning the use of outdoor water features, and stringent enforcement of water wasting laws. More severe measures may include using child safe pool covers to reduce evaporation, banning turf irrigation and banning car washing. It also states that a drought surcharge could be imposed. None of those is currently in force and none is tied to a named stage.
Not really, and the city publishes why. It states that it recycles nearly all of its highly treated wastewater, and it names the destinations: golf courses, parks, non-edible crops, the Tres Rios Wetlands, recharging groundwater aquifers, and cooling at the Palo Verde Nuclear Generating Station. What leaves a drain in this city has customers waiting at the other end of the treatment train, which is a decent reason to ask a contractor what happens to what comes out of your line.
That is a fair question and it deserves a straight answer rather than a defensive one. Jetting uses water deliberately, and a city under a declared water alert is a reasonable place to ask whether a job needs it. The honest counterweight is that a line cleared properly once tends not to need clearing repeatedly, and repeated visits are not free of water either. The decision about whether a given line is a candidate at all belongs to the diagnosis rather than to the machine, and that is covered elsewhere on this site.
No. The Drought Management Plan, the Stage 1 declaration, Chapter 37 and the stormwater discharge list are City of Phoenix instruments. Neighbouring valley municipalities publish their own drought plans, their own stormwater programmes and their own hotlines, and a property with a Phoenix postal address is not necessarily a City of Phoenix utility customer. The test used throughout this site is the name at the top of the bill rather than the address on the envelope.
Sources, and What We Deliberately Left Out
The Drought Management Plan, its 1990 adoption under Chapter 37 Sections 121 through 130.2, the June 2022 Stage 1 Water Alert declaration, the four stage names, the Article X authority, what Stage 1 calls for, the conditional list of possible future restrictions and the reclaimed water destinations are all from the City of Phoenix Water Services Department drought pages.
The statement that only stormwater belongs in the storm drain, the twenty item list of allowable non-stormwater discharges with its significant-pollutants condition, the outfall inspection and dry-weather screening method, the use of closed circuit television to trace a flow to its source and the Stormwater Hotline number are from the same department’s illicit discharge detection and elimination page.
No source disagreement was found between those two documents. One deliberate blank is printed in the table above rather than filled: the city lists four drought stages and separately lists restrictions it might impose, without mapping the two together, so no mapping is offered here.
No rate, fee or surcharge figure is quoted. The city states that a drought surcharge could be imposed and gives no amount, and no amount is invented here.
Deliberately not covered here, because this site already covers them properly. The method itself in every respect, including operating pressure, nozzle behaviour, the camera-first rule and the warning about jetting a structurally failed pipe, all of which our national hydro jetting page owns and none of which improves by being restated with a city name attached. The question of when a line is a candidate for jetting rather than for cabling, which the main Phoenix page answers in print. The city’s own sewer cleaning equipment and programme, which our Phoenix drain cleaning page owns.
Also left out: the one-time temporary discharge permit route for putting something into the sanitary sewer, which belongs to our Phoenix commercial plumbing page and is named here rather than explained. The city’s water supply sources and their proportions, which the main Phoenix page owns. The excavation permitting regime, which our Phoenix sewer line repair page owns. Billing consequences of water loss, which our Phoenix leak detection page owns.
For the work itself see hydro jetting, drain cleaning and sewer line repair, or get in touch. For the wider region see our Arizona service areas.
No office, address, crew or response time of ours is stated for Phoenix, and we are not claiming to be based in this city.
Everything above was read from City of Phoenix published pages at the time of writing. Drought stages are declared and terminated by the water services director, and the stage in force can change without notice to anybody reading a web page. Code articles, allowable discharge lists and hotline numbers all change too. Nothing here is a quotation of record, a legal opinion, or a substitute for asking the body that holds the pen.
