Plumber Irving TX: This City Owns Its Water 75 Miles Before It Gets Here
Almost every city page on this site answers the question “who supplies your water” with the name of somebody else. Irving is the rare case where the answer is the city itself, and the complication is that the city owns the water a very long way from the tap. Irving holds water rights in a lake in northeast Texas, moves that water across five counties into a reservoir it does not own, and then pays the City of Dallas to treat it. Nobody sells Irving its supply. Dallas sells Irving a service.
That arrangement is not trivia. It decides what comes out of your fixtures, who you call when a main breaks, and which set of rules a licensed plumber has to satisfy before touching a backflow assembly on your property. Everything below is what the City of Irving publishes about its own system, read on 1 August 2026, with the sources named at the foot and the figures we refused to state named beside them.
There Are At Least Three Places Called Irving Park, And None Of Them Is This City
This page is about the City of Irving in Dallas County, Texas, the municipality between downtown Dallas and DFW International Airport. It is not about Irving Park in Chicago, which is a neighbourhood on the northwest side of that city. It is not about Irving Park, Old Irving Park or New Irving Park in Greensboro, North Carolina, which are three adjacent residential districts there. And it is not about Irvington, which is the name of established neighbourhoods in Portland, Indianapolis and Fremont.
We are stating that plainly because a search for the bare word is ambiguous in the data and unambiguous on the ground. If you are reading this from a Chicago or Greensboro address, nothing on this page describes your utility, your ordinance or your pipe. If you are reading it from a Texas address between Loop 12 and the airport, all of it does.
A Plumber Irving Customers Call Is Working On The End Of A Fifty Year Project
The City of Irving states that most of its water is pumped from Lake Chapman to Lewisville Lake and then treated for Irving by the City of Dallas. It states that it owns water rights to water in Lake Chapman, which was previously known as Cooper Reservoir, and that some water is purchased directly from Dallas to supplement the Chapman water. Lake Jim Chapman sits just east of Commerce and north of Sulphur Springs, in the far northeast corner of the state.
The city tells the history as a fifty year project. The lake was identified as a solution in 1964. Water rights were contracted from the Army Corps of Engineers in 1968. Fourteen years of legal battles over environmental concerns followed. Ground was broken for the dam in 1986, construction finished in 1991, and water finally arrived in Irving in June 2003. The city calls it the largest public works project it has ever undertaken, and says it was paid for phase by phase with only a ten cent per thousand gallons rate increase across five decades of development.
Two later facts matter for anyone thinking about long term supply. The city puts the 1991 construction and land acquisition phases at about 8.5 million dollars with a delivery capacity of 75 million gallons per day and room for expansion. And in February 2025 the original transfer pipeline was tied to a newly constructed 32 mile transmission line from Lake Ralph Hall, which the Upper Trinity Regional Water District expects to be a major supply by the end of 2026.
Who Owns The Water, Who Owns The Container, And Who Is In Control
Most supply questions are answered with a single name. This one cannot be, because the answer changes four times between the lake and the meter while the owner of the water stays the same. Read the grid as three separate columns of fact rather than one story.
Lake Chapman
A federal reservoir. Irving does not own the lake. It owns a contracted right to water stored in it, secured from the Army Corps of Engineers in 1968 and flowing since 2003.
The transfer pipeline
Upper Trinity Regional Water District states the Chapman pipeline is jointly owned by the City of Irving and UTRWD, and operated by the city. Irving is the operator of its own import.
Lewisville Lake
The delivery point, and not an Irving asset. The water is discharged into a reservoir the city does not control, and remains Irving water while it sits there.
Elm Fork plant
Dallas pulls the water from Lewisville and treats it at the Elm Fork Water Treatment Plant. The city describes the current Dallas contracts as being for treatment and for a supplemental backup.
735 miles of main
From the plant onward it is Irving’s again. The Water and Wastewater Repairs Division reports over 735 miles of water main, and maintains the isolation valves that let a repair happen without shutting a neighbourhood.
Your service line
The last leg is yours. The city completed a full inventory of utility owned and customer owned service lines, so for once both halves of that boundary have been mapped rather than assumed.
The contrast worth drawing is with the suburbs on the other side of the metroplex. McKinney and Richardson both receive water from the North Texas Municipal Water District, and Lake Chapman appears in their story too, because the district counts it among its raw sources. But those cities buy finished water from a body that holds the rights. Irving holds the rights itself and buys only the treatment. Same lake, opposite position in the contract.
Two City Documents Give Two Different Distances, So We Print Both
The city page describing the project states that the water must travel almost 75 miles through Delta, Hopkins, Hunt, Collin and Denton Counties before flowing into Lewisville Lake. The flow diagram inside the 2024 Water Quality Report labels the transfer main as 33 miles of 72 inch pipe. Those are not the same number and the city does not explain the difference anywhere we could find.
The likely explanation is that one figure describes a single constructed segment and the other describes the whole journey including the river and reservoir reaches. That is a guess, so we are not publishing it as a finding. We print both figures with the document each came from and leave the reconciliation to the city. The same report names a Hackberry Pump Station, a 12 million gallon reservoir and a 1 million gallon control tank along the route, while the supply page names a booster pump station at Princeton. We are not asserting how many lifts there are, because no single document we read states the number.
Backflow In Irving Is A Paperwork Problem Before It Is A Plumbing Problem
Backflow prevention exists on most of our city pages and the general explanation is not worth repeating. What is worth stating is how Irving specifically administers it, because the administration is where jobs go wrong. The city runs its cross connection control programme in cooperation with the Texas Commission on Environmental Quality, and Ordinance 8140 requires every customer with a backflow prevention assembly to have it tested annually.
The part that catches contractors is the order of operations. The city states that verification of a plumbing permit is necessary for any newly replaced or installed assembly before testing, and that this can be confirmed with the City Plumbing Inspector or the Backflow Specialist. Test a new assembly without the permit already verified and the report is not simply late, it is out of sequence.
- Physical copies of test reports and registration forms are no longer accepted at all. Everything goes through the online system, Envirotrax.
- Reports must be submitted within ten days of the test date, which the city ties to City Ordinance Sec. 41-22 (h).
- The submission fee is 40 dollars, and there is no fee for a failed test report.
- Tester registration costs 100 dollars, runs for one year, and must be renewed before expiry to keep the ability to file at all.
- A copy of the actual test form, not just the invoice, must be given to the customer for every test performed.
- On a failure the customer must be told the assembly needs repair or replacement and a retest.
- Replacement assemblies must be noted as such on the report, including the old serial number.
- Each tester needs a unique email address, because it is tied to the profile and cannot be shared.
For a property owner the practical reading is short. If a company offers to test your assembly and cannot tell you its Irving registration status or which system it files in, it is not going to produce a report the city will accept. That matters most on commercial premises, where the assembly is usually the reason the water account exists in the form it does.
Irving Finished Its Service Line Inventory And Reports No Lead At All
The 2021 Revised Lead and Copper Rule required every water system in the country to complete a service line inventory by 16 October 2024 and keep it publicly available. Most of the cities on this site came out of that exercise with a count of lead lines, a replacement schedule and a funding argument. Irving came out of it with a zero.
The city states that Irving Water Utilities identified and mapped all utility owned and customer owned water service lines, that the city has no lead water service lines, and that the three year project was completed on time as required by federal and state agencies. It publishes the inventory for inspection and points to the drinking water test data section of its water quality report for lead and copper results.
Read that carefully, because a zero on service lines is not a zero on lead. Service lines are the pipes between the main and the building. Solder inside a house built before the 1986 federal ban, a brass fixture of the wrong vintage, or a galvanised interior run are all inside the building envelope and none of them is a service line. The inventory is genuinely good news about the buried half of the problem, and it says nothing whatsoever about the half under your own floor. If that distinction matters to your household, a leak detection and pipe survey answers the interior question that the inventory was never designed to.
Irving Collects The Wastewater And Somebody Else Treats It
The supply side is unusual because Irving owns more of it than you would expect. The waste side is conventional by comparison. The city states that Irving Water Utilities maintains just over 670 miles of gravity flow wastewater collection lines and eleven lift stations, and that the department ensures delivery of the wastewater to the Trinity River Authority Central Regional Wastewater System for treatment.
What the city says about its own maintenance is more useful to a homeowner than the mileage. It reports cleaning almost two million linear feet of pipe each year and using video inspection to evaluate pipe condition and plan replacement. That is a utility that surveys before it digs, and it sets a reasonable expectation for what you should ask of anyone working on your side of the boundary. A sewer line repair quoted without a camera survey behind it is a quote written from assumption.
The Trinity River Authority appears on several of our North Texas pages because it is the regional answer for a lot of this metroplex. Arlington covers the regional education partnership that sits alongside it, and Carrollton covers what happens when a city straddles more than one county while doing all of this.
Where Irving Actually Wants Your Used Cooking Oil
The city is direct about what causes sanitary sewer overflows. It names fats, oils and grease first, and names the items it wants kept out of the toilet without hedging: cooking oil, bacon grease, meat fats, food scraps, shortening, lard, butter, margarine, gravy, mayonnaise, salad dressings and sour cream, then disposable wipes, paint and paint thinners, motor oil, hair and clothing dye, tanning solutions, and anything flammable.
The practical instruction is the part most cities leave vague and Irving does not. Water Utilities accepts used cooking oil year round at 333 Valley View Lane, in sealed containers, placed in the yellow cage near the flag poles. The city specifies vegetable based oils such as sunflower, cottonseed, peanut and canola in one gallon sealed containers, and says residents unable to make the trip should contact Solid Waste Services for pickup. During the holidays the same material is collected under the regional Holiday Grease Roundup and recycled into biofuel.
Irving also participates in Defend Your Drains North Texas, the regional education campaign, and it repeats the warning that wipes labelled flushable still cause blockages. None of this is advice we invented and none of it is unusual guidance, but the drop off location and the container rules are specific to this city and are the sort of detail that decides whether a household actually complies. When it fails anyway, that is when a drain cleaning call gets made.
Four Business Days, And Why Your Water Sometimes Runs Cloudy
Irving asks for more notice before excavation than a lot of people expect. The city states that before any construction or digging you should contact Irving Water Utilities and the Texas Excavation Safety System at least four business days before starting, and that Water Utilities may ask for a representative to be present at the scheduled locate. Franchise utility companies must supply a franchise permit number, and the city says locates will not be completed without it.
The disclaimer attached to that service is the sentence worth reading twice. The city states that all lines will be located in the approximate area of the main, and that such locating does not absolve excavators from responsibility for damages regardless of the accuracy of the locate or whether the city provided the service at all. Responsibility for protecting water and sewer facilities during the work sits with the excavator, along with a duty to report damage promptly.
The flushing rules answer a different complaint. The city says it flushes hydrants only when necessary for health and safety, and lists four triggers: a TCEQ mandate to flush known dead end mains once a month, complaints of air in the lines or colour or odour issues, clearing a main after a repair, and flushing new installations before the bacteriological sampling required to activate them. If your water goes cloudy or discoloured shortly after street work nearby, that sequence is the likely explanation and it is not a fault inside your house.
Dental Offices, And The Municipalities Next Door
Irving is the designated regulatory authority for the federal effluent guidelines that keep mercury bearing dental amalgam out of publicly owned treatment works. The city requires a one time compliance report submitted to it, and a fresh report within thirty days if a dental office changes ownership or modifies its operations. We are not explaining amalgam separators in general here because our Brentwood, California page already covers the hardware and the federal replacement deadline in full. What is Irving specific is simply who receives the paperwork, and the answer is the city itself rather than a regional authority.
On geography, Irving sits in Dallas County between Dallas proper and DFW International Airport, and it shares boundaries with a number of separately governed municipalities. Each has its own building department, its own inspectors and its own utility billing, and an address that feels like Irving may not be in it.
DFW International Airport is on that list deliberately. It is a jointly owned airport authority with land inside more than one city, which means a parcel near it can sit under a different permitting path than the street it faces. Las Colinas, the large planned district in the north of the city, is not a separate municipality despite frequently being spoken of as one. It is Irving, and Irving rules apply to it.
Plumber Irving Questions, Answered From What The City Publishes
Everything here is sourced from City of Irving pages and its own water quality report, read on 1 August 2026, with the disagreements printed rather than smoothed over.
The City of Irving states that most of its water is pumped from Lake Chapman, formerly Cooper Reservoir, to Lewisville Lake, and is then treated for Irving by the City of Dallas. Irving owns water rights to water in Lake Chapman and buys some water directly from Dallas to supplement it. Upper Trinity Regional Water District states that the Chapman pipeline is jointly owned by the City of Irving and UTRWD and operated by the city.
Not in the usual sense. The city describes its current Dallas contracts as being for treatment and for a supplemental backup, alongside some directly purchased water. The supply itself is a right Irving contracted from the Army Corps of Engineers in 1968. Dallas treats Irving water at the Elm Fork Water Treatment Plant. Your bill still names whoever invoices you, and for most Irving addresses that is the City of Irving.
The city gives two different figures in two different documents and we are not reconciling them. The project history page says the water must travel almost 75 miles through Delta, Hopkins, Hunt, Collin and Denton Counties before flowing into Lewisville Lake. The flow diagram in the 2024 Water Quality Report labels the transfer main as 33 miles of 72 inch pipe. Both are the city’s own numbers.
The city states that it has none. Irving Water Utilities identified and mapped all utility owned and customer owned water service lines under the 2021 Revised Lead and Copper Rule, completed the three year project on time, and reports no lead water service lines. That covers the pipe between the main and the building. It does not cover lead solder, brass fixtures or interior pipework inside an older house, which no service line inventory looks at.
Annually. Irving’s Ordinance 8140 requires all customers with backflow prevention assemblies to have them tested every year. Reports must be filed through the online Envirotrax system within ten days of the test date, which the city ties to Ordinance Sec. 41-22 (h). Physical copies are no longer accepted. For a newly installed or replaced assembly, the city requires the plumbing permit to be verified before the test happens.
At least four business days, and to both Irving Water Utilities and the Texas Excavation Safety System. The city may also ask for a representative to attend the locate. Note the city’s own disclaimer: lines are marked in the approximate area of the main, and the locate does not absolve the excavator of responsibility for damage regardless of its accuracy.
If it followed nearby street or hydrant work, flushing is the likely cause. The city flushes known dead end mains monthly under a TCEQ mandate, flushes in response to colour, odour or air complaints, flushes after a repair to clear air and sediment, and flushes new mains before the bacteriological sampling that activates them. None of those is a fault inside your home, though a persistent problem after the water clears elsewhere might be.
Water Utilities accepts it year round at 333 Valley View Lane, in sealed containers placed in the yellow cage near the flag poles. The city asks for vegetable based oils such as sunflower, cottonseed, peanut and canola in one gallon sealed containers. Residents unable to deliver it can contact Solid Waste Services for pickup. During the holidays the same material is collected under the Holiday Grease Roundup and recycled into biofuel.
Chapman Lake To Your Fixture, And The Last Few Feet Are Yours
Irving spent fifty years making sure the water arrives. What happens after the meter is still a private plumbing question, and it is the one we answer. Tell us the symptom and the address and you will get a straight answer about whether it is yours, the city’s, or a boundary argument that needs settling before anybody digs.
What We Read, And What We Would Not State
The supply description, the Lake Chapman water rights, the Cooper Reservoir former name and the direct purchase from Dallas are from the City of Irving water supply page. The project chronology is from the city account of the supply project.
That page is the source for the 1964 identification, the 1968 Army Corps contract, the fourteen years of legal challenge, the 1986 groundbreaking, the 1991 completion and the June 2003 arrival. It is also the source for the 8.5 million dollar figure, the 75 million gallons per day delivery capacity, the ten cent per thousand gallons financing statement, the almost 75 miles across five named counties, the Elm Fork treatment arrangement and the February 2025 tie in to the 32 mile Lake Ralph Hall transmission line.
The joint ownership of the Chapman pipeline and its operation by the city are from Upper Trinity Regional Water District, which is a second and independent source for that specific point. The 33 mile 72 inch main, the Hackberry Pump Station, the 12 million gallon reservoir and the 1 million gallon control tank are from the flow diagram inside the city 2024 Water Quality Report.
The backflow ordinance number, the Envirotrax requirement, the ten day filing rule, the fee figures, the permit verification rule and the tester duties are from the city cross connections and backflow page. The service line inventory result is from the city lead and copper rule page. The collection mileage, the eleven lift stations, the Trinity River Authority destination, the 735 miles of water main, the grease and drain guidance, the hydrant flushing triggers, the locate requirements and the tap and relocation changes are from the corresponding city water utilities pages. Everything was read on 1 August 2026.
What we refused to state, and why. We refused to reconcile the 75 mile and 33 mile figures, for the reason given in full above. We refused to state how many pump stations or lifts the transfer involves, because one document names a Princeton booster station and another names a Hackberry station and no document we read gives a total.
We refused every water and sewer rate. The water quality report prints an average summer bill and several per gallon comparison figures, but it does not label them in a way we could read reliably out of the document, and a rate we cannot attribute is a rate we will not publish. We refused the six way percentage breakdown of where a dollar of water spending goes, for the same reason: the percentages and the categories are both printed and we could not confirm which belongs to which.
We refused any hardness, chlorine or contaminant figure for Irving, because the treated water is produced by another city’s plant and we did not read a current result we could stand behind. We refused any tap fee, meter deposit or permit fee, because the city states tap fees correspond to the size needed and publishes no single number. We refused to say which addresses fall inside which neighbouring municipality, and we refused any claim about the condition of the pipe under any particular street.
No office, address, crew or response time of ours is stated for Irving. Ordinances, fees, programme rules and contracts change, and this city has an active supply expansion running through the end of 2026. Confirm anything that matters with Irving Water Utilities before relying on it. The 24 hour water and sewer hotline and the Valley View Municipal Complex address are published by the city on the pages linked above.
