Plumber Tacoma WA: One Factory Closed And Every Household Bill Moved, To The Cent
In August 2023 an Atlanta packaging company announced it would close its Tacoma paper mill at the end of September. Tacoma Public Utilities published what that meant for the water system, and the number is difficult to believe on first reading. That single customer accounted for approximately one third of overall daily use of the utility water, which the utility describes as equal to the water use of more than 100,000 homes.
Then it published the consequence. To make up the revenue shortage, drinking water rates rose 5 per cent, on top of an already approved system average increase of 4 per cent, effective 1 January 2024. The residential average increase was stated to the cent: $2.28 a month if you live in Tacoma, $3.03 a month if you live in the surrounding service area.
Read the last part again. The household outside the city pays more per month for the closure of a factory inside it. That is the shape of this city on every plumbing question worth asking, and the rest of this page is written around it. Everything below was read on 2 August 2026 from Tacoma Public Utilities, and the parts we could not reach are named at the foot rather than guessed.
The boundary answer
Your bill is set partly by a customer who is no longer there
Most cities on this site draw a line between two bodies, or between a homeowner and a utility. Tacoma draws a line through time. The utility states that the mill closure resulted in a $25 million annual revenue loss for Tacoma Public Utilities, and that the financial impact to Tacoma Water in particular is significant because the mill accounted for approximately one third of overall daily drinking water use.
Two things follow for a household, and both are practical. The first is that the water rate here is not purely a function of what it costs to treat and deliver your water. Part of it is the absence of somebody else. The second is that the utility said out loud what it would do about it: review ways to increase revenue from other sources and reduce costs by potentially delaying capital projects.
A delayed capital project is a plumbing fact, not an accounting one. It is the difference between a main that gets replaced on schedule and one that does not, and it is why the utility own leak and pressure guidance is worth reading here rather than skimming. The utility also stated that enhanced residential assistance programmes would offset the increase for qualifying income thresholds.
Nine permit desks, one responsible utility, and it issues none of the permits
This is the sentence that decides how a backflow or irrigation job runs in this service area, and Tacoma Water puts it plainly. While your local jurisdictions issue the permits, Tacoma Water is ultimately responsible for all cross connections. The permit authority and the responsible party are different bodies, and there are nine of the former.
The utility names them all. Tacoma goes to the Building and Land Use Office. Federal Way goes to the Permit Center. Fircrest and Lakewood go to Building Permits. King County goes to Environmental Health Services. Pierce County goes to Planning and Land Services. Puyallup goes to Building Services. Ruston goes to Permits and Licenses. University Place goes to Building, Plumbing and Mechanical Permits.
The practical consequence is that two identical houses two streets apart can sit under two different permit desks and one water utility. If you are in Puyallup, your permit comes from Puyallup Building Services and your cross connection is still Tacoma Water responsibility. A contractor who works across this boundary regularly should be able to tell you which desk yours is without looking it up, and if they cannot, that is a useful signal.
One thing the utility does keep to itself, and it is the fast part. It inspects assemblies on installation or replacement and periodically afterwards, tags the ones it approves, and states that most inspections are accommodated within one business day. Inspection requests go online, or to 253-502-8731. The permit may take a while. The inspection usually does not.
Whether the assembly may physically exist where somebody wants to put it
Most utilities publish a list of approved devices and stop. Tacoma Water publishes a fourteen point installation specification with actual measurements in it, which means a homeowner can stand over the work and check it. These four numbers are the ones that decide placement.
12 inches, maximum depth
For an assembly installed below ground in an irrigation box, the top of the assembly can be no deeper than 12 inches from the finished elevation. Deeper is not a preference, it is outside the requirement.
6 inches, minimum clearance
Assemblies smaller than two and a half inches need a minimum of six inches of clearance underneath. Assemblies of two and a half inches and larger need a minimum of one foot, and must also be supported to prevent damage.
Between 1 and 5 feet up
Every above ground assembly must sit between one and five feet above the finished floor elevation, unless a permanent platform is installed to make testing and maintenance possible.
Not there at all
Assemblies must not be installed in crawl spaces or attics, in any environment with toxic, corrosive or hazardous fumes, or where a spillage or a relief valve operation would create a hazard, the example given being next to electrical switchgear.
Two more rules from the same document earn their place on any job sheet. Every assembly bypass must have backflow protection equivalent to the assembly being bypassed, which is the rule most commonly broken by a well meant temporary arrangement. And in a vault, a permanently installed ladder is required for safe access, plugs must be installed in each of the test cocks and must fit snugly, and provision for water drainage must be made.
A collision worth building on
Two towns, one crawl space, opposite answers
We have written this location before and the comparison is the reason it is here again. In Cary, an assembly inside a crawl space, under a deck, inside a shed or in a closed restricted access structure puts you outside the town testing programme, and you become responsible for arranging your own test and submitting the results. The location is allowed. The service is withdrawn.
Tacoma takes the other position entirely. Its published requirements state that assemblies must not be installed in crawl spaces or attics. Not discouraged, not excluded from a programme, not permitted. That is a rule about where the pipework may go rather than a rule about who tests it, and it lands hardest in exactly this housing stock.
West of the Cascades a great many houses sit over a crawl space rather than a basement, which is precisely why the rule matters here more than it would in a slab city. If somebody has already put an assembly under your floor, that is not a testing question to resolve at the next annual. It is an installation question, and the honest answer is that it needs to move.
The utility list, and why the hazard grade decides the hardware
Tacoma Water names the common cross connections directly. Irrigation or in-ground sprinkler systems. Fire sprinkler systems. Boilers. Swimming pools. Radiant or solar heat systems. Chemical dispensers at wash basins and service sinks. Auxiliary water supplies such as wells and storage tanks. If any of those exist on the property, the utility says you need backflow prevention.
The device is then chosen by hazard grade rather than by convenience, and the utility publishes its own acceptance rule. In general it accepts air gaps and reduced pressure backflow assemblies for high hazards, and double check valve assemblies, pressure vacuum breaker assemblies and atmospheric vacuum breakers for low hazards. That is the whole decision in one sentence, and it explains why two neighbours with different equipment get quoted different devices.
- The assembly must be on the current State of Washington Department of Health approved list, or must have been listed at the time of the original installation.
- Testing is by a State of Washington certified backflow assembly tester, on installation, on repair, on replacement, and annually thereafter.
- The utility requires a copy of each test report. A repair visit is not finished until the retest exists on paper.
- Every assembly must be installed in the physical orientation for which it was approved. The right device fitted the wrong way round is the wrong device.
- The utility warns that its published requirements are general and may not include the specific requirements of your particular jurisdiction, which is the nine desks problem again in a single sentence.
For landscape irrigation specifically there is a separate document, Guidelines for Installation of Backflow Prevention Assemblies on Landscape Irrigation Systems, which the utility says is available at the Tacoma Water permit counter or by calling. We have not quoted from it because we have not read it, and a guideline nobody opened is not a source.
Finding it before the bill does
Notifications, and the square of ground the utility needs
Residential customers can enrol in leak notifications through the utility online account. The route is published: register or log in, go to notification preferences under quick links, find the water leak notifications section and choose email, text or both. The alert fires on water use changes that may indicate a leak or a burst pipe. There is a separate high usage notification with an alert percentage set against your own average daily usage.
One asymmetry worth knowing if you run a shop or a restaurant here. Business customers can enrol in high usage notifications, but the utility states they will not receive water leak notifications at this time. A commercial property therefore has to watch its own baseline rather than wait to be told, which is an argument for a scheduled check rather than a reactive one.
The meter itself comes with an access condition that quietly decides whether any of this works. The utility asks for a clear workspace of at least three feet by three feet in front of the meter, with obstacles removed, including overgrown vegetation and parked vehicles. If the meter sits behind a locked gate, it asks to be given access information such as a key or a code. A meter survey may produce a vegetation trim notice or a request for access notice.
The test the utility asks you to run first
Before anything else, the utility says to use your water meter and usage data to confirm the suspicion. Turn off every faucet and every water using appliance, including dishwashers and sprinklers, and use no water during the test. It is the same discipline everywhere and it is worth repeating because most disputed bills are settled by it in ten minutes.
Its scale figures are national rather than local and we mark them as such. The utility cites nearly one trillion gallons wasted in United States homes each year from easy to fix leaks, an average of 10,000 gallons per home per year, and states that finding and fixing household leaks can save more than 10 per cent on a water bill. Common causes it names are running toilets, dripping faucets and leaking valves, and it notes that an unexplained increase, particularly after freezing weather, may be a sign of a leak. Where the meter says the fault is not a fixture, leak detection is the next step rather than a shovel.
On the freeze half of that sentence, this is a mild but genuinely wet corner of the country, and the failures happen in the unheated runs rather than in the middle of a buried line. Our guide on burst pipe repair covers the aftermath, and the state page linked at the foot covers the housing stock argument for this side of the Cascades.
Sewer here belongs to a different department, and we could not reach it
Drinking water in Tacoma comes from the utility. Wastewater and stormwater are run by the City Environmental Services department on a separate website, which did not respond to us at all on the day we read everything else. Not a refusal from the site, not an error page, no response. We are not going to describe a sewer ownership rule we did not read.
What we can do is point at the neighbours, because Puget Sound cities differ sharply on this exact question and the differences are documented. In Seattle the property owner owns the side sewer all the way to the public main under the street, which is about as far as that line is drawn anywhere in the country. In Bellevue the city publishes its side sewer permit conditions in plain language, including which pipe couplings are not allowed on the lateral.
In Lynnwood the split is finer again, between the building side sewer and the service lateral, with different duties on each. Three cities inside an hour of here, three different answers. Until we can read the Tacoma document ourselves, treat the ownership question as open and get it in writing from the department before anybody excavates. Our sewer line repair page covers the work itself.
Tacoma plumbing work, booked against nine permit desks and one water utility
An irrigation assembly somebody put in a crawl space. A test report that was never filed after a repair. A permit question that turns on which side of a boundary the house sits. A meter nobody has been able to reach for two years because a hedge grew. A bill that moved and a household that cannot tell a rate change from a leak. We will tell you which of those is pipework and which is paperwork before anybody quotes.
Leak detection
Meter test first, excavation last, and a written result either way. Leak detection
Water heaters
Soft west side water is kind to tanks, which changes the replacement argument. Water heater repair
Drains
Cleaning that separates a recurring cause from a one off blockage. Drain cleaning
Sewer lines
Camera survey before any decision about digging or lining. Sewer line repair
Emergencies
No water, water everywhere, or a meter that will not stop. Emergency plumbing
Nearby
Same depth on the cities either side of the boundary. Puyallup
Tacoma plumbing questions, answered from what the utility publishes
Every answer below is drawn from Tacoma Public Utilities pages read on 2 August 2026. Where we could not reach a source, we say so instead of filling the gap.
One likely reason is published. After the paper mill closed at the end of September 2023, the utility raised drinking water rates by 5 per cent to cover the revenue shortage, on top of an already approved system average increase of 4 per cent, effective 1 January 2024. It stated the residential average effect as $2.28 a month inside Tacoma and $3.03 a month in the surrounding service area. That is a rate change rather than a consumption change.
Your local jurisdiction, not the water utility. Tacoma Water states that while local jurisdictions issue the permits, it is ultimately responsible for all cross connections, and it names nine desks: Tacoma Building and Land Use, Federal Way Permit Center, Fircrest Building Permits, King County Environmental Health Services, Lakewood Building Permits, Pierce County Planning and Land Services, Puyallup Building Services, Ruston Permits and Licenses, and University Place Building, Plumbing and Mechanical Permits.
No. The published requirements state that assemblies must not be installed in crawl spaces or attics. That is stricter than some places we cover, where an assembly in a crawl space is allowed but excludes you from a town testing programme. Here it is a rule about where the pipework may be, which matters because so much housing on this side of the Cascades sits over a crawl space rather than a basement.
The top of the assembly can be no deeper than 12 inches from the finished elevation. Assemblies smaller than two and a half inches need at least six inches of clearance underneath, and assemblies of two and a half inches and larger need at least one foot and must be supported to prevent damage. Assemblies in vaults need a permanently installed ladder, snug plugs in each test cock and provision for drainage.
Between one and five feet above the finished floor elevation, unless a permanent platform is installed to allow testing and maintenance. The requirements also bar any location where a spillage or a relief valve operation would create a hazard, giving the example of a position adjacent to electrical switchgear or panels, and any environment containing toxic, corrosive or hazardous fumes.
On installation, on repair, on replacement, and annually thereafter, by a State of Washington certified backflow assembly tester. The utility requires a copy of each test report, so a repair is not complete until the retest has been filed. The assembly must also be on the current State of Washington Department of Health approved list, or have been listed at the time of the original installation.
Faster than most permit processes. The utility inspects assemblies on installation or replacement and periodically afterwards, tags the ones it approves, and states that most inspections are accommodated within one business day. Requests can be made online or by telephone on 253-502-8731. The permitting half of the job sits with your local jurisdiction and runs to its own timetable.
Residential customers can, through the utility online account. Register or log in, open notification preferences under quick links, find water leak notifications and choose email, text or both. You will be alerted to water use changes that may indicate a leak or a burst pipe. There is also a high usage notification with an alert percentage. Business customers can use high usage notifications but the utility states they do not receive water leak notifications at this time.
So it can inspect and read it. The published request is for a clear workspace of at least three feet by three feet in front of the meter, with obstacles removed, including overgrown vegetation and parked vehicles. If the meter is behind a locked gate the utility asks for a key or code. A meter survey may result in a vegetation trim notice or a request for access notice, so a hedge is not a neutral decision.
We are not going to tell you, because we could not read the document. Wastewater here is run by a separate City department on a website that did not respond to us at all on the day we read everything else, and an ownership rule is exactly the sort of thing that should not be inferred. Get it in writing from the department before anybody excavates. Nearby cities differ sharply on this, which is the reason for the caution rather than an argument against it.

The August 2023 announcement and 30 September 2023 effective date, the comparison of that usage to more than 100,000 homes, the 5 per cent increase on top of an already approved 4 per cent system average increase, the 1 January 2024 effective date, the $2.28 and $3.03 average monthly residential figures and the enhanced assistance for qualifying income thresholds are from the WestRock-related Water Rates page.
The cross connection examples, the hazard grading of accepted devices, the approved list requirement, the annual testing rule and the test report requirement are from the utility Cross Connection Control page. The statement that local jurisdictions issue permits while the utility is ultimately responsible for all cross connections, and the nine named permit desks, are from Cross Connection How To.
Every measurement in the placement section, the crawl space and attic prohibition, the switchgear and fumes exclusions, the bypass protection rule, the orientation rule, the vault ladder, test cock plugs and drainage provisions, the support requirement, the one business day inspection statement and the telephone number are from Backflow Assembly Requirements. The leak notification route, the business customer exclusion, the meter test instruction and the national scale figures are from Find and Fix Leaks. The three foot by three foot clearance, the locked gate instruction and the trim and access notices are from Meter Information.
A disagreement inside one publisher, printed rather than resolved. The closure FAQ frames the loss as a $25 million annual revenue loss for Tacoma Public Utilities, which is the whole utility including power. The rates page frames the same customer as approximately one third of overall daily use of the water and equal to more than 100,000 homes, which is a water volume claim. The two are compatible and they are not the same claim. We state each against its own source and we do not combine them into a water revenue figure, because neither page publishes one.
Refused and left blank rather than estimated. The entire wastewater and stormwater side of this city, including sewer ownership, lateral responsibility, side sewer permits, rates and any backup policy. The City department that runs it publishes on a separate website which returned no response at all to us on the day of reading, and an ownership rule is not something to infer from a neighbouring city.
Also refused. Every water rate in dollars per unit, because the pages we read publish the change rather than the schedule. The landscape irrigation installation guidelines, which the utility says are available at its permit counter and which we did not obtain, so nothing is quoted from them. Water hardness figures and any softener recommendation. The current status of any delayed capital project, which the utility raised as a possibility rather than a plan. And the permit fee at any of the nine jurisdictions named above, none of which we opened.
