Federal Way, King County, Washington
Plumber Federal Way: You Own the Whole Pipe, and Halfway Along It You Stop Being Allowed to Touch It
Most cities answer the sewer question with ownership. They publish a line, they tell you which side of it is yours, and the argument is about who pays. Federal Way is served by a water and sewer district that answers a different question, and it is the one that actually decides who turns up at your address with a machine.
Lakehaven Water and Sewer District defines two pipes between your toilet and the main under the street. You own both of them. The first, on your own land, you are expressly permitted to work on yourself. The second, in the public right of way, may only be worked on by a firm the district has approved in advance, and the district publishes that list in public.
That is not a technicality. It is the reason a household in this city can be told that a repair of ten feet is straightforward and a repair of thirty feet needs a different company entirely.

Two Definitions, One Continuous Pipe, and a Permission Line That Moves
Lakehaven publishes a standard for the installation of gravity building sewers and side sewers, updated in February 2025. Before it reaches a single dimension it does something unusual. It defines two separate pipes, and it defines them by where they sit rather than by who holds the title to them.
- A privately owned and maintained pipeline located within private property.
- It begins where the building drain ends, as the plumbing code defines that, and it terminates at the property line, the right of way margin, or the boundary of a Lakehaven easement.
- Work on it may be performed by the property owner in person, provided the materials and workmanship meet the district standard and the owner holds Lakehaven harmless for any damage arising from the installation.
- Also privately owned and privately maintained, and carrying exactly the same sewage.
- It sits within the public right of way or a Lakehaven easement, running from the end of the building sewer to the public main.
- Work on it shall be performed by a Lakehaven approved side sewer contractor maintaining the required bonding and a current insurance certificate. There is no owner exemption.
Read those two definitions together and the effect is clear. The pipe never changes owner. It does not even change material in most cases, because the standard requires the side sewer to match whatever the public main is made of. What changes at the property line is the set of people who are legally permitted to open the ground above it.
The permit that goes with all this is called a Sewer Service Connection Permit, known locally as a side sewer permit, and the district requires one for installation and for repair. One detail in that process is worth knowing before anybody quotes you. Where the work sits in the public right of way, Lakehaven states that it will obtain the right of way construction permit from whichever authority has jurisdiction. You are not sent to a second counter to fetch it yourself.
The Published List
Twenty Eight Names, and Most of Them Are Not Plumbers
The approved side sewer contractor list is a public document on the district website. We read it and counted twenty eight firms. We are not going to reproduce their names, telephone numbers or addresses here, for the same reason we declined to do it on a city that publishes contractor ratings. The mechanism is the useful part, and printing other firms on our own page is not something we are willing to do.
What is worth reporting is the shape of it. The great majority of the twenty eight trade under excavation, construction, earthworks, dirt or utility names. Only a handful carry a plumbing, sewer or drain name at all. That tells a homeowner something practical before the first phone call: a side sewer replacement in this district is an excavation job with an authorisation attached to it, and the trade most people would instinctively ring is under represented on the only list that matters.
The second observation is geographic. Five of the twenty eight give an address in Federal Way itself. The rest are scattered across Auburn, Kent, Milton, Puyallup, Sumner, Enumclaw, Buckley, Gig Harbor, University Place, Graham, Tacoma, Everett and, in one case, Chehalis, which is roughly sixty miles south. The authorisation is district wide and the firms holding it are regional.
The practical instruction is short. Before anybody quotes for work that will reach past your property line, ask whether they are currently on the Lakehaven approved list. It is a yes or no question with a published answer, and the district notes that the list changes reasonably often, so a copy from last year is not evidence about this year.
If Your Sewer Has to Pass Under an Old Asbestos Cement Water Main, You Buy the Water Main
Buried in the installation standard is a paragraph about crossings. Where a gravity building or side sewer is constructed under an existing asbestos cement water main, the district may require the contractor, at the contractor’s own expense, to replace that portion of the water main with new ductile iron pipe and transition couplings meeting current Lakehaven standards, extending a minimum of two feet into both trench walls.
Read that slowly. The water main is public. It is not your pipe, you did not choose its material, and its age has nothing to do with you. But if your sewer has to go under it, the replacement is priced into your job. In practice a contractor’s expense is a homeowner’s expense with one invoice in between.
The standard then closes the obvious cheap escape route. Portland concrete cradles and controlled density fill cradles are expressly not allowed to support the existing asbestos cement main. You cannot prop up the old pipe and carry on underneath it. If it is in the way and it is that material, a length of it is coming out.
This is why an estimate for underground work here can move by a large amount after the ground is open, and why it is worth asking the question before the machine arrives rather than after. Ask whoever is quoting whether they have checked the material and the depth of the water main on your frontage, and what happens to the price if it is asbestos cement. A firm that has done work in this district will know exactly what you are asking about.
Inside the House
The City Publishes the Exact Point Where a Repair Becomes New Work
The city has its own jurisdiction, separate from the district, over the plumbing inside the building. Its residential permit exemption list is taken from section R105.2 of the residential code, and the plumbing entries are unusually precise about where a repair stops being a repair.
Stopping a leak in a drain, water, soil, waste or vent pipe is exempt. But the same clause continues: if any concealed trap, drain pipe, water, soil, waste or vent pipe becomes defective and it becomes necessary to remove and replace it with new material, that work shall be considered as new work, and a permit shall be obtained and an inspection made.
The second exemption covers clearing stoppages, repairing leaks in pipes, valves or fixtures, and the removal and reinstallation of water closets, provided the repairs do not involve or require the replacement or rearrangement of valves, pipes or fixtures. So lifting a toilet to reach a blockage and putting the same toilet back is exempt. Putting a different one back is not.
And then the list ends with a sentence that quietly reopens everything above it. Unless otherwise exempted, separate permits may be required for the exempted items, and the city says to call the Permit Center if in doubt. That is an unusual thing to publish, and the honest reading is that it is an invitation to ask rather than an invitation to assume.
Three Code Vintages Running at Once, and a Plumbing Code With Two Chapters Removed
Federal Way publishes the list of construction codes it enforces, and it is not a single edition. It is three, layered.
| Code | Edition adopted | Local note |
|---|---|---|
| Uniform Plumbing Code | 2021 | Adopted excluding chapters 12 and 15, with Washington state amendments |
| International Residential Code | 2021 | With appendices H and J, excluding chapter 11 and chapters 25 through 43 |
| International Mechanical Code | 2021 | With Washington state amendments |
| International Fuel and Gas Code | 2018 | Three years behind the plumbing and mechanical codes |
| International Energy Conservation Code | 2018 | Alongside a 2021 Washington State Energy Code |
| National Electrical Code | 2023 | The newest edition on the list |
Those exclusions are not decorative. Chapters 12 and 15 of the plumbing code are the fuel gas piping and firestop chapters, and the city has taken them out because other adopted codes carry that ground. If somebody quotes a plumbing code chapter number at you here, it is worth checking that the chapter is one the city has actually adopted.
There is a date attached to all of it. The city states that new building codes took effect on 15 March 2024, that applications deemed complete after that date meet the 2021 editions as amended by the state and by the city, and that applications submitted before it, together with their subsequent revisions, are reviewed under the 2018 editions. An old permit therefore carries an old rulebook with it, which matters if you are finishing work somebody else started.
Whose Utility Is It
The District Is Older Than Its Own Name, and It Serves Six Communities
The King County Board of Commissioners incorporated Lakehaven Sewer District on 27 February 1956, by resolution. In September 1985 voters authorised the consolidation of King County Water District Number 124 into it, and the merged body took the name Federal Way Water and Sewer District. A second merger, with Water District Number 56, completed in November 1987. In August 1994 the name changed again, to Lakehaven Utility District, and in October 2016 to Lakehaven Water and Sewer District.
That is a municipal corporation of the state of Washington, not a city department, and for a stretch of nine years it carried this community’s name and then handed it back. Anybody assuming the city runs the pipes has the wrong body, which is a genuinely easy mistake to make when the city hall and the district office are a few minutes apart.
The customer list makes the point again. The district names six communities it serves: Auburn, Des Moines, Federal Way, Kent, Milton and Tacoma, plus the school district and the local fire and rescue authority as named organisations. It states that it serves most of the City of Federal Way, small portions of Auburn, Pacific, Tacoma, Des Moines and Milton, and roughly eighteen square miles of unincorporated King County north of Federal Way and west of Auburn.
The word most is doing real work in that sentence. Being inside the city limits is not proof that Lakehaven is your utility, and being outside them is not proof that it is not. Check the bill rather than the address.
Two District Pages Give Two Different Sewer Systems
We print contradictions between a body’s own documents when we find them, because a household that finds one on its own usually concludes that somebody is being careless with them. This one is small and entirely benign, and it is worth knowing about.
The history page
Describes a sewer system of 350 miles of mainline with 27 pump stations, feeding two secondary treatment plants.
The sewer services page
Describes 312 miles of sewer lines, including gravity pipe and pressurised force mains, and 32 pump stations.
The detail that reconciles part of it
Three of those 32 pump stations are maintained by Lakehaven under contract with the City of Edgewood, which is a different city again.
What both pages agree on
Two plants. The Redondo plant is designed for an average flow of 4.32 million gallons a day and the Lakota plant for 10 million.
Neither figure is wrong in any way that matters to a homeowner. The likeliest explanation is that one page counts everything the district maintains and the other counts only what it owns, which is exactly the distinction the Edgewood contract creates. We use the smaller and more recently written figures where we use any, and we would not treat either page as authoritative for a legal or engineering purpose.
The water side is quoted consistently in both places: about 400 miles of mainline, 22 wells, 12 storage tanks holding roughly 31 million gallons, and an average pumping rate near 10.6 million gallons a day, across about 35 square miles serving a population of roughly 112,000. Around three quarters of the land area is single family housing, which is why so much of the district’s published material is written for householders rather than for developers.
Three Numbers
A Locate That Can Be Too Old, a Shared Pipe That Caps at Three, and a Trench That Waits
The first number is the locate window. State law requires utility locates before excavation and almost everybody publishes a minimum. Lakehaven publishes a maximum as well: locates shall be requested not less than two business days and not more than ten business days before excavation, except in emergencies, by calling 811. A locate that has been sitting for a fortnight is not a valid locate, so a job that slips by a week may need the marks done again.
The second is the shared connection cap. No building sewer may be connected to a neighbour’s building sewer, or to a side sewer serving an adjacent property, without prior written approval from the district, a shared use agreement and private easements. Where sharing is allowed, no more than three single family residences may jointly use one sewer service connection. Older streets do contain these arrangements, and finding out you are on one is much cheaper before a sale than after.
The third is the inspection sequence. A minimum of twenty four hours notice is required for inspection of building sewers on private property and of side sewers in the right of way, requested by email. The trench must be de-watered before the inspector arrives, and approval of both the installation and the leakage test results is required before the trench is backfilled and compacted. Leakage testing itself is by water exfiltration or low pressure air, under district observation.
Why a Plumber Federal Way Households Hire May Ask You to Start a Fortnight Early
The city runs its permitting electronically, and there is a step in front of the electronic step that catches people out. Applications requiring review must be submitted electronically, but you cannot simply upload them. You first request a document upload link, the city sets up a file for the project, and it then sends you the link. The city states plainly that you will not receive it immediately and that it can take a few days to process the request.
- Request the upload link before anything else
This is the step with an unpredictable wait attached, and the city asks you to be very detailed in the request to avoid delays. Doing it on the day you decide to go ahead costs nothing and can save a week.
- Know which days the counter exists
Permit Center staff are available from nine in the morning until four in the afternoon on Monday, Tuesday, Thursday and Friday. The Permit Center is closed to the public on Wednesdays. Email and telephone are the routes on that day.
- Book residential plumbing permits through the regional portal
Residential electrical, mechanical and plumbing permits are applied for through a shared Puget Sound permitting portal rather than a Federal Way specific system, and inspections are scheduled through the same family of sites. The old telephone booking system is being retired.
- Expect up to forty eight hours on an inspection, and know who gets priority
The city does not guarantee an inspection time and says it may take up to two days depending on workload. Priority is given to homeowners, concrete inspections, reroofs and other time or weather sensitive work. Anything not done on the requested day is automatically moved to the next working day with priority status.
- Clear the five things that void the visit
An inspection will not be performed, and a reinspection fee may follow, if the approved site copy of the permit, plans and inspection card is not on site, if the address is not clearly posted, if the inspector cannot access the work, if there are unrestrained pets on the site, or if there is no adult over eighteen present to give access to an occupied home. Access includes providing any special equipment such as a ladder, which is a requirement we have seen published in one other city on this site.
The dog is not a joke. A plumbing inspection in this city can fail with every joint correctly made, purely because nobody put the dog in the back bedroom, and a reinspection fee is the published consequence. It costs nothing to fix and it is the single easiest way to lose two days.
Every Meter in the District Was Replaced, and It Finished in June 2025
The district completed a full automatic meter reading rollout across roughly 32,000 meters. The board approved the contract in February 2018, installation started in October 2019 and it completed in June 2025. Every meter older than five years was replaced in the process.
Two consequences matter to a household. The first is that your meter is now almost certainly new, so a wildly high bill is less likely to be a failing register than it used to be, and more likely to be water genuinely leaving the system somewhere. The second is that the district states the new meters record and store daily usage information that can be used to identify leaks. A continuous overnight draw on a house where nothing is running is the clearest leak signal there is, and it now exists in the record rather than only on a dial you would have to watch.
If you suspect a leak on your side of the meter, that daily history is the cheapest evidence available before anybody starts opening walls. Our leak detection page covers what happens after the usage data has told you there is something to find, and the district itself owns everything up to and including the meter, so the split between whose problem it is has a physical marker you can stand next to.
Work We Take On in Federal Way
The list below is the ordinary residential range. Where a job is going to cross the property line into the right of way, the approved contractor rule above governs who may carry it out, and we will say so rather than let you find out from an inspector.
Drain cleaning
Blockages, recurring slow drains and root intrusion in older clay and concrete runs.
Sewer line repair
Camera survey first, then a scope that respects where the permission line falls.
Leak detection
Starting from the meter data rather than from a guess about which wall.
Water heater work
Repair and replacement, including the permit question that a replacement raises.
Emergency plumbing
For the failure that will not wait for a counter to reopen on Thursday.
Plumber Federal Way Questions, Answered From the District and the City
Answers taken from Lakehaven Water and Sewer District and City of Federal Way published pages. Several of them send you to somebody other than us, which is what the sources actually say.
Most likely Lakehaven Water and Sewer District, which is a municipal corporation of the state and not a department of the city. The district states that it serves most of the City of Federal Way, plus parts of Auburn, Pacific, Tacoma, Des Moines and Milton, and around eighteen square miles of unincorporated King County. The word most matters, so check the name on your bill rather than assuming from your address.
On your own property, the district’s installation standard says the property owner may perform the work on the private building sewer, provided all materials and workmanship meet the standard and the owner holds the district harmless for any resulting damage. Once the pipe passes into the public right of way or a district easement it becomes the side sewer, and only a Lakehaven approved side sewer contractor with bonding and current insurance may work on it.
The district publishes the authorised sewer service contractor list as a document on its own website, and it notes that the list changes reasonably often. Ask any firm quoting for work past your property line whether they are currently on it, then check the current version rather than a saved copy. We do not reproduce the list here.
The city’s residential exemption list says stopping a leak in a drain, water, soil, waste or vent pipe is exempt. But if a concealed trap or pipe has become defective and has to be removed and replaced with new material, the same clause says that is considered new work and a permit shall be obtained with an inspection made. The list also ends by saying separate permits may still be required for exempted items, so the safe move is to ring the Permit Center.
Removing and reinstalling a water closet is on the city’s exempt list, provided the work does not involve or require the replacement or rearrangement of valves, pipes or fixtures. Taking the same toilet off to reach a blockage and refitting it is the exempt case. Fitting a different unit, or moving the pipework to suit it, is not the same job in permitting terms.
One published reason is specific to this district. If the work has to pass under an existing asbestos cement water main, the district may require the contractor to replace that section of the public main with new ductile iron at the contractor’s expense, extending a minimum of two feet into both trench walls, and concrete or controlled density fill cradles are not allowed as an alternative. Ask about the main on your frontage before the ground is opened.
The district’s standard requires locates to be requested not less than two business days and not more than ten business days before excavation, except in emergencies, by calling 811. The upper bound is the unusual part. If the job slips, the marks may need to be redone.
Only with prior written approval from the district, a shared use agreement and private easements. Where sharing is permitted, no more than three single family residences may jointly use a single sewer service connection. If you are buying, this is worth establishing early, because a shared connection changes who has to agree before anything is repaired.
The city lists them. No approved site copy of the permit, plans and inspection card on site. An address that is not clearly posted. No access to the work, including not providing special equipment such as a ladder. Unrestrained pets on the site. And no adult over eighteen present to give access to an occupied home or business. A reinspection fee may be assessed in those cases.
Because it is closed to the public that day by design. Staff are available from nine to four on Monday, Tuesday, Thursday and Friday, and the city gives an email address and a telephone number for other times. Plan the counter part of a job around that rather than discovering it midweek.
King County runs a septic system maintenance rebate of up to five hundred dollars per property for regular inspection, pumping or riser installation, and the district links to it. The county material also notes that disclosing a septic system failure is a seller’s duty under state law. There is a separate county side sewer repair rebate factsheet linked from the same district page, but the file would not open for us, so we are not stating its terms.
Yes, Federal Way in King County, between Seattle and Tacoma. The name is unique in the United States, which is unusual and makes this one of the few city pages on this site where there is no risk of confusion with a similarly named place. It comes from Federal Highway 99, by way of a 1929 school district consolidation, rather than from a person.
How This Page Was Built
Every requirement, date and figure above was read from Lakehaven Water and Sewer District and City of Federal Way published pages and documents during this build. Nothing here is inferred from how neighbouring Puget Sound jurisdictions work, which matters more here than usual, because six of them already have pages on this site and they do not agree with each other.
The contradiction we found, printed rather than smoothed over
Two district pages describe two different sewer systems. The history page gives 350 miles of mainline and 27 pump stations; the sewer services page gives 312 miles and 32 pump stations, three of which the district maintains under contract for another city entirely. Both are the district’s own words. We have said so above rather than picking one silently.
What we refused to write, and why
The largest refusal is the most tempting document in the folder. The district’s installation standard contains a full set of construction specifications, and we have used almost none of them, because our Bellevue page already covers that ground in detail for a city twenty miles away. Our Tacoma page compares how several neighbouring cities divide sewer responsibility, so no ownership explainer is repeated here either. That refusal is the reason this page is about permission rather than about ownership.
We refused backflow and cross connection compliance, although the district publishes both a premise isolation standard and a testing document, because that subject is covered thoroughly elsewhere on this site and our Tacoma page already names this city’s own permit counter inside it. We refused grease and wipes, which is most of what the district’s sewer page is about, for the same reason. We refused the district’s water service line survey material, which is the lead and copper subject, for the seventh page running. We refused frozen pipe guidance, which the district also publishes and which is worked heavily across this site already.
We refused every rate, fee, charge and connection cost, and every laboratory value, hardness figure and treatment performance figure. We refused all dimensional detail from the installation standard, partly because it belongs to the specification refusal above and partly for an honest technical reason: several measurements in that document are rendered in a symbol font that did not survive text extraction, and a pipe cover depth is exactly the sort of number that must not be guessed at.
A note on the numbers behind this page
Two web addresses built from this city’s name plus a plumbing word look, at a glance, like local firms. Both turned out to be domains parked for sale, advertising themselves as brandable names, and neither serves a secure connection at all. We mention it only to explain why we did not treat those phrases as somebody’s trading name when measuring demand here. The general point about city names in web addresses is written up properly on another page on this site rather than repeated at length here.
A note for anyone retracing our steps
Both bodies answer ordinary automated requests on every path used here. Two structural warnings. First, the district runs on two hostnames and the older one now points at the newer, so a saved link may be a redirect. Second, and more usefully: the household material is split across two organisations that do not cross reference each other much. Pipes, connections, contractor authorisation and inspection of the sewer sit with the district. Permits, codes, exemptions and building inspection sit with the city. Looking in one place finds you half the answer.
Start with the district’s water and sewer availability and service page for the installation standards and the authorised contractor list, its history page for the incorporation dates, the name changes and the system figures, its sewer services page for the second set of system figures and the responsibility statement, its areas served page for the six communities, and its water service page for the meter programme. On the city side, the Permit Center page carries the opening days and the document upload link process, construction codes carries the adopted editions and the March 2024 date, residential permit exemptions carries the plumbing exemptions, and inspection information carries the scheduling rules and the reasons an inspection is not performed.
Elsewhere on this site, our Washington overview covers state licensing and the split between the wet west and the freezing east, Seattle, Tacoma, Bellevue, Renton, Lynnwood and Puyallup cover the neighbouring jurisdictions, each of which answers these questions differently. For the work itself see drain cleaning, sewer line repair, leak detection, hydro jetting, water heater repair and emergency plumbing, or get in touch.
No office, address, crew or response time of ours is stated for Federal Way, and we are not claiming to be based in this city. We are not on the Lakehaven approved side sewer contractor list and do not claim to be; the district publishes that list itself and it governs work in the public right of way.
Everything above was read from Lakehaven Water and Sewer District and City of Federal Way published pages at the time of writing. Installation standards are revised on published dates, code adoptions change, contractor lists are updated, rebate programmes open and close and counter hours are altered. Nothing on this page is a quotation of record, a legal opinion, or a substitute for asking the body that holds the pen.
