Plumber Kent WA: The Meter Decides Which Counter, and the Sewer Permit Will Not Travel Alone
Kent publishes something most cities leave people to find out the hard way. It states, in one line on its development engineering page, exactly where the boundary between two entirely different permits falls: modifications between the meter and the home require a plumbing permit, and plumbing permits are handled by Building Services rather than by the engineers who deal with the service itself.
On the same page it attaches a condition to the sewer permit that catches people out. You need one for any repair, replacement or installation of a side sewer, and the city states that applications will not be accepted without a building application submitted alongside them.
There is also a set of drawings of the pipes on your own property sitting in a city filing system, in two different departments, which the city will hand over if you ask. Most people never find out, and pay for a survey that finds the same thing.
Three Doors, and the City Tells You Which One Is Yours
Most cities describe their permits by what they are called. Kent describes them by where the work is, which is much more useful, because a householder always knows where the work is and almost never knows what the permit is called.
- Sewer permit. Required for any repair, replacement or installation of a side sewer. Applications are not accepted without a building application submittal.
- Water permit. Required for any new water service, or when making changes to existing water service. Same rule about the building application.
- Also the source of a certificate of sewer availability, a certificate of water availability, a water flow certificate, and, where the available flow turns out to be insufficient, a fire flow certification.
- And two documents whose existence tells you something: a shared sewer utility notice and a shared water utility notice. Shared services are common enough here to have their own paperwork.
- Everything between the meter and the house. The city states it plainly: modifications between the meter and the home require a plumbing permit, and plumbing permits are found at Building Services.
- Sewer as-builts, meaning the record drawings, including for private sewer lines.
- Sewer connection questions, which is not the same conversation as a sewer permit.
The building application condition on the sewer permit is worth planning around rather than discovering. A homeowner whose only intention is to replace a failing side sewer is being told that the sewer application does not stand on its own. That is a sequencing problem, not a cost problem, and it is the sort of thing that turns a two week job into a six week job if it is found out on the day somebody tries to file.
The Cheapest Thing on This Page
The City Already Holds Drawings of the Pipes on Your Property
Two separate Kent pages, written by two different departments and not cross referenced to each other, say the same useful thing. The sewer page states that as-builts for private sewer lines come from Economic and Community Development. The private drainage page states that if you are not sure whether your property contains private stormwater facilities, Public Works Engineering may already have a site plan on file for it, and that detailed drainage information can be obtained by submitting a public records request for the storm as-built drawings and the building plans.
Put those together and the practical instruction is short. Before paying anybody to establish where a pipe runs on your land, ask the city whether it has the drawing. The two departments hold different halves of the answer and neither of them sends you to the other.
This matters most in three situations. Buying a property and wanting to know what is buried in the garden. Planning an extension, a driveway or a garage where a machine is going to be digging. And working out why water is standing somewhere it did not used to, which is often a private drainage structure nobody has looked at in years rather than anything to do with the sewer.
It is worth being clear about what a drawing does and does not replace. A record drawing tells you where a pipe was put and roughly how deep. It does not tell you whether the pipe is broken, root filled, bellied or disconnected, and it does not always match what is actually in the ground. That is what a camera survey is for. Getting the drawing first usually makes the survey shorter and cheaper, because the camera is looking for a condition rather than hunting for a route.
The Residential Plumbing Permit Is Filed Under a Name With No Plumbing in It
Kent has moved residential plumbing permits onto its permitting portal, and it publishes the exact sequence of dropdown choices you need. Application type: minor work permits. Sub type: plumbing. Work type: residential.
Read that first one again. A householder or a contractor looking for a plumbing permit will search the portal for the word plumbing and find nothing under the heading they expect, because the top level category is called minor work. It is not hidden and it is not a trick. It is simply a naming convention that makes sense to the people who built the form and not to the people filling it in.
Two other things on the same set of pages are worth knowing before anybody starts. The city publishes a separate residential mechanical permit application, so a job that touches both plumbing and mechanical work is not one submission.
And on the development engineering page, in the same paragraph that gives the correct contact address for that section, a second version of the address appears with the word development misspelled. We are not reproducing either spelling here, for the same reason we declined to reproduce a similar error on another city page in the same week: a typo that gets copied travels further than one that stays put. Copy the address from the page, read it back a character at a time, and ring the number if nothing is acknowledged.
The number is worth having in any case. Development Engineering and Economic and Community Development share a telephone number, which is the clearest signal available that the two conversations, permits and records, start in the same place even though the web pages treat them as different worlds.
On Your Own Land
A Duty to Inspect That Some Kent Properties Carry Without Anybody Mentioning It
The city cites its own code requiring all storm and surface water to be controlled in a manner that eliminates potential or existing flooding and water pollution. That is an obligation on the owner, not on the utility.
Then it goes further. It says that if your property has a stormwater facility maintenance covenant, you should make sure you are meeting your required inspection frequency, which is usually at least once a year. A covenant is attached to the property rather than to the person, so a buyer inherits it, and the number of buyers who are told about it at the point of sale is not high.
The city’s own recommendation is more than the minimum: annual inspections, or better, twice a year, once in the wet season and once in the dry. And it draws its own line clearly, which is worth quoting in substance because it tells you where help stops. Staff are available to provide technical guidance on maintaining private stormwater facilities, but they cannot provide engineering services or resolve private property issues.
Its published checklist before you call is sensible and free. Work out how surface water is supposed to leave your property and where it goes, because an obstructed flow path is often the whole problem, and in autumn a catch basin lid buried under leaves is a genuinely common cause of standing water. Check catch basins, yard drains and connecting pipes for blockage. And look at where the downspouts actually discharge, because a downspout emptying above ground beside the house is the cheapest flooding problem there is to fix.
A Foam Cube Through the Main, and Why You Should Switch Off the Water Heater
Kent cleans its water mains by a method it describes openly, and it is not the usual open the hydrant and let it run.
- The method
A fire hydrant is disassembled and a foam cube is inserted into the main. Water pushes the cube along a section of pipe and out through a second disassembled hydrant at the far end. The city says the purpose is to remove inorganic build up on the pipe walls and any sediment that has collected over time.
- You get told first
The city notifies impacted residents and businesses before flushing an area and puts sandwich boards out with further information. If you have had a notice, this is what it is about.
- Store water and then leave the taps alone
The city asks people to draw and store enough water for the interruption, and then to refrain from using or turning on any faucets during the shutdown. Running a tap during a flush is how sediment gets pulled into a house.
- Turn off the energy source to the water heater
This is the instruction worth acting on and the one most people miss. The city states that turning off the energy source to your water heater may help prevent possible damage or problems from the main flushing. A tank that fires on an interrupted supply is a tank that can be damaged, and a water heater is a great deal more expensive than the two minutes it takes to switch it off.
- Then restore it deliberately
Bring the water back first, run a cold tap until it is clear, and only then put the heater back on. If the water is still discoloured when you get there, that is the flush rather than a fault, and it should clear on its own.
The second operation is quieter and just as relevant. The city states that it locates and marks all underground city-owned utilities for the 811 one-call programme itself. That means the marks on your verge before a dig are the city’s own work, and it also means the city knows exactly what it has and where. Anything not marked is, by elimination, either private or not there, which is a useful thing to establish before a machine arrives.
Kent also runs rebates on water efficient toilets and washing machines, which is worth checking before a replacement appliance is ordered rather than after.
What the Plumber Kent WA Households Call Is Actually Connected To
The numbers appear here once, as scale, and nothing is built on them. The sewer division operates, maintains and repairs 211 miles of sewer pipe, 5,755 manholes and seven sewer pump stations. The water system is made up of wells, interties and spring supplies, with pumping stations, pressure reducing and reservoir facilities behind them.
The systems are separate
Kent states that unlike many places its drainage and sanitary sewer systems are not combined, and that the sanitary system is designed only for sewage. Surface and storm water are not permitted into it.
More than one water provider
The city states that Kent residents are served by multiple water utility service providers and gives two phone numbers for finding out which one covers an address. It does not publish a map.
The valley floods and the city says so
Kent writes that despite completed drainage projects the valley remains prone to flooding, and that sometimes all its crews can do is let people know. Sand and sandbags are free from the operations facility.
King County treats the sewage
The city’s own permit page carries King County capacity forms for residential and non-residential work, which is the clearest sign of where the pipe eventually goes.
One deliberate omission. Because storm and sanitary are separate here, there is an obvious diagnostic argument about what it means when a sanitary problem gets worse in wet weather. That argument is set out properly on another city page on this site and we are not repeating it, because a second version would be longer rather than better.
The other cross-boundary fact worth knowing is on our Federal Way page. The water and sewer district based there lists Kent as one of six communities it serves, which is a reminder that a city limit and a utility boundary are two different lines, and that the second one is the one that decides who you ring.
Work We Take On in Kent
Before anything is booked we establish which side of the meter the work falls on, because that decides the permit and the department, and whether a records request would save a survey.
Drain cleaning
Blockages and recurring slow drains, including the root problems common in older valley properties.
Sewer line repair
With the sewer permit condition and the building application requirement settled first.
Leak detection
House side of the meter, which is where the plumbing permit jurisdiction begins.
Hydro jetting
For grease and scale where cabling alone keeps buying a few weeks at a time.
Water heater work
Repair and replacement, and the rebate question before an appliance is ordered.
Emergency plumbing
For the failure that will not wait for a portal, a counter or a records request.
Plumber Kent WA Questions, Answered From the City’s Own Pages
Answers taken from City of Kent published public works and permitting pages. Several of them send you to a city department rather than to us, which is what the sources actually say.
For work between the meter and the home, the city states that a plumbing permit is required and that plumbing permits are handled by Building Services. Residential plumbing permits go through the city permitting portal, and the city publishes the exact route: application type minor work permits, sub type plumbing, work type residential. The first of those three is the one people miss.
A sewer permit from Development Engineering, which the city says is required for any repair, replacement or installation of a side sewer. There is an important condition attached: the city states that applications will not be accepted without a building application submittal. Plan the sequence around that rather than discovering it at the counter.
The city says as-builts for private sewer lines come from Economic and Community Development, reachable on 253-856-5490. That is a different department from the one that maintains the sewer. It is worth asking before paying for any investigation, because a record drawing is the cheapest way to learn where a pipe runs.
Public Works Engineering may already hold a site plan for the property, and the city says so explicitly for anybody unsure whether they have private stormwater facilities. For detail, it directs you to submit a public records request for the storm as-built drawings and the building plans. Two departments, two halves of the answer, and no cross reference between the pages.
The city cites its storm and surface water code as requiring all storm and surface water to be controlled so that potential or existing flooding and water pollution are eliminated. Separately it notes that a property with a stormwater facility maintenance covenant has a required inspection frequency, usually at least once a year. A covenant runs with the property, so it can be inherited without anybody mentioning it at the sale.
It can. Kent cleans mains by pushing a foam cube through a section of pipe between two disassembled fire hydrants, to remove build up and sediment. It asks residents to store water in advance and not to turn on any faucets during the shutdown, and it states that turning off the energy source to your water heater may help prevent damage or problems from the flushing. That last one takes two minutes and is worth doing.
The city states that its water section locates and marks all underground city-owned utilities for the 811 one-call programme. So the marks are the city’s own work rather than a contractor’s. Anything on your land that is not marked is either private or not there, and that is a useful thing to establish before a machine arrives rather than after.
Not necessarily the city. Kent states that residents are served by multiple water utility service providers, and rather than publishing a map it gives two phone numbers, Public Works Operations and Utility Billing, for finding out which service area covers an address. A neighbouring water and sewer district also lists Kent among the communities it serves. Check the name on your bill.
The city is unusually candid about this. It says that despite major drainage projects and continuing improvements the Kent Valley remains prone to flooding, that crews inspect and clean catch basins and pipes, remove sediment, clean detention and filter vaults and replace failing pipe all year, and that sometimes all they can do is let people know. Sand and sandbags are available free from the operations facility.
Yes, Kent in King County, in the valley between Seattle and Tacoma. There is also a Kent in Ohio, home of Kent State, and Kents in Connecticut, New York, Illinois, Indiana, Iowa, Michigan, Minnesota and Texas, Kent Counties in Delaware, Maryland, Michigan, Rhode Island and Texas, and Kent in England, which is a county of roughly 1.8 million people. None of the permits, departments or code sections here apply to any of them.
Because the name is heavily shared and one of the sharers is memorable. When we measured demand for this city we found a large block of searches naming a firm in Austin, Texas whose trading name puns on a comic book character, and a further block naming towns in Kent, England. We counted only phrases that name Washington explicitly and refused the rest rather than treating somebody else’s market as ours.
How This Page Was Built
Every requirement, figure and instruction above was read from City of Kent published pages during this build. Nothing is inferred from how neighbouring King County cities work, which matters here, because six of them already have pages on this site and none of them routes permits the way Kent does.
What we refused to write, and why
We refused a private sewer ownership explainer, which is the obvious way to write a Puget Sound page, because Tacoma already compares several neighbouring cities on exactly that, Bellevue publishes its construction conditions and Federal Way covers the permission question. We refused the diagnostic argument about separated storm and sanitary systems, although Kent states that its systems are separate, because another city page on this site sets that reasoning out in full.
We refused the city’s lead and copper service line material, which is thorough and includes a full inventory and a large field investigation programme, because that subject is covered repeatedly elsewhere on this site and this is the eighth page running on which we have declined it. We refused the city’s grease and wipes programme for the same reason. We refused every rate, fee, permit charge and rebate amount, every laboratory value and any hardness figure.
We also refused to build a second section this week about a city publishing a misspelled contact address, even though Kent does it too. One page on this site already covers that properly, and a method turns into a mannerism faster than a subject does.
A note on the numbers behind this page
This is one of the most contaminated city names we have measured. The pool of search phrases containing the word Kent is nearly five times the size of the pool that names Washington. Almost a quarter of it is one trading name belonging to a plumbing firm in Austin, Texas that puns on a comic book character, and a further block is made up of phrases naming towns in Kent, England, including one row that is simply a British web address.
An automated tool had filed several of those English rows under American states, apparently because towns like Dover, Rochester and Ashford also exist in the United States. We counted only phrases that explicitly name Washington, then removed a duplicated phrase, a plumbing supply merchant search and a named local competitor. Our Rochester page already states that Rochester in Kent, England is a different place and is not counted behind it, which is the same discipline applied from the other end.
A note for anyone retracing our steps
The city website refuses ordinary automated requests and has to be read in a real browser. The material is split across departments in a way that is worth flagging: water and sewer operations under Public Works Operations at one address, drainage and development permits under Public Works Engineering at another, sewer records under Economic and Community Development, and plumbing permits under Building Services through the portal. Four doors, and no single page lists all four.
Start with the city’s development engineering page for the sewer and water permits, the certificates and the meter boundary, its residential plumbing permit page for the portal route, its sewer page for the system figures and the as-built route, its water page for the multiple providers statement, the 811 marking and the main cleaning method, its private drainage page for the code duty, the covenant and the checklist, and its drainage and flooding page for the valley statement and the sandbags.
Elsewhere on this site, our Washington overview covers state licensing and the split between the wet west and the freezing east, and Seattle, Tacoma, Bellevue, Renton, Federal Way, 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 Kent, and we are not claiming to be based in this city.
Everything above was read from City of Kent published pages at the time of writing. Permit routes, portal categories, department responsibilities, system figures and rebate programmes all change. Nothing on this page is a quotation of record, a legal opinion, or a substitute for asking the body that holds the pen.
