Plumber Waco TX: Two Charges On Your Bill Are Measured From An Aeroplane, Not A Meter
Almost everything on a municipal utility bill answers to a meter. Use more, pay more. Fix the leak, the number falls. Waco carries two monthly charges that do not work that way at all, and one of them is set by a photograph taken from the air.
The larger of the two is the Municipal Drainage Utility System fee. It is calculated from the area of hard surface on your parcel, the roof and the driveway and the patio, because that is what generates runoff. The City reads that area from aerial imagery, checked against McLennan County Appraisal District records and building permits. Turning the water off does not reduce it. Leaving the house empty does not reduce it. The City states plainly that if a property gets no water bill from the City, a separate drainage account is opened anyway, regardless of occupancy.
The smaller is the street maintenance fee, a flat two dollars a month on a single-family home, with an exemption available to a household that keeps no registered vehicle at all.
This matters to plumbing work in a way that is easy to miss. Digging a driveway to reach a sewer line, pouring a new slab over a repipe or replacing a cracked patio all change the measured quantity, the tiers are steps rather than a slope, and the aircraft that does the measuring comes round roughly every two years. Everything below was read in August 2026 from the City of Waco, every source is named and linked at the foot, and where the City puts a path behind its own robots file we say so instead of reading it.
The Two Lines That Do Not Move When The Water Stops
Waco City Council approved the drainage fee in November 2020 and held implementation back until 1 October 2021. The City describes the drainage system it pays for as an asset worth over 750 million dollars with some components more than a hundred years old, and the fee is dedicated, meaning it cannot legally be spent on anything except stormwater work: maintenance and repair of pipes, inlets and culverts, street sweeping, litter clearance and compliance with state and federal stormwater rules.
The street maintenance fee is dedicated in the same way, to transportation only. The City gives its reason in physical terms: roughly 1,534 lane miles of street excluding the interstate and other on-system TxDOT roads, 72 bridges and 180 traffic signals. The fee currently funds about 12 per cent of what the City spends on street maintenance in a year, which is a candid number to publish next to a charge.
Both are collected on the monthly utility bill, which is why they are a plumbing subject rather than a civics subject. They sit on the same piece of paper as the water and the wastewater, they are affected by building work rather than by consumption, and they are the two lines a homeowner is most likely to assume a repair will change when it will not.
| Charge | What it is measured from | Does a leak repair change it |
|---|---|---|
| Water consumption | The meter, in 1,000 gallon increments, on five tiers | Yes, immediately |
| Wastewater volume | Water use, capped by a three month winter average | Yes, but capped and lagged |
| Water and wastewater base | Meter size, and whether you are inside the city | No |
| Drainage fee | Square feet of impervious cover, read from aerial imagery | No, unless the work changes hard surface |
| Street maintenance fee | Land use, and whether a vehicle is registered there | No |
How It Is Actually Calculated
Three Steps, Two Numbers, And One Of Them Is In The Municipal Code
The unit is the Equivalent Residential Unit. The City fixes one ERU at 2,633 square feet of impervious cover, which it states is the average for a single-family home inside the city limits, and it cites its own municipal code section 26-400 for that figure. The drainage rate set by Council is $6.55, dated 16 June 2025 on the City page. Your monthly fee is the ERU multiplied by that rate.
For a single-family house the ERU is not a ratio at all. It is one of four fixed values chosen by band: nothing under 500 square feet, 0.57 between 500 and 1,960, 1.0 between 1,960 and 3,400, and 1.74 above 3,400. For multi-family and non-residential property the City switches method entirely and divides the measured area by 2,633, then rounds to the nearest non-zero whole number.
The City publishes two worked examples and they are worth repeating exactly. A homeowner whose map record shows 1,700 square feet falls in the 0.57 band and pays $3.73 a month. A business with a 50,000 square foot store and a 30,000 square foot car park has 80,000 square feet, divides by 2,633 to get 30.38, rounds to 30 and pays $196.50.
The consequence of a banded ladder is the thing nobody mentions. Adding a thousand square feet of paving in the middle of a band costs nothing. Adding forty square feet across the 1,960 line moves a house from 0.57 to 1.0, which is a 75 per cent increase on that line of the bill and it is permanent.
Your Sewer Repair Can Change A Charge That Has Nothing To Do With Sewers
Very little residential plumbing work in Waco happens without hard surface being lifted. A collapsed line under a driveway means the driveway comes up. A repipe under a slab often ends in new concrete. A cleanout put in properly is set in a pad. None of that is unusual. What is unusual is that in Waco the finished surface area is a billable quantity, and the bill it lands on is the same one your water arrives on.
The direction of the change is not always upward, which is the part worth planning around. Replacing a cracked concrete apron with permeable material, or simply not putting back a section of slab that was only ever there to cover a line, reduces impervious cover. If that takes a parcel back across 3,400 or 1,960 square feet it moves a band, and the saving repeats every month for as long as the property stands.
The measurement is the other half of it. The City derives impervious area from three sources: the Find My Drainage Fee Map, McLennan County Appraisal District data, and the original building plans. The imagery behind the map was flown in 2023, with February 2025 imagery in processing at the time of reading, and the City says it is refreshed roughly every two years. So a change you make this spring may not appear on the bill for a long time, in either direction, and the map is the record rather than your permit.
There is an appeal, and there is a condition attached to it that is easy to read past. The City provides an appeal form for a fee you believe is wrong, and states that while the appeal is under review you are still required to pay. Get the map record checked before the concrete goes down rather than after, and if the work is going to involve breaking ground at all our sewer line repair service is the right starting point for scoping it.
The exemption list is worth reading for the same reason. Alongside the obvious public bodies it exempts property with less than 500 square feet of impervious cover, and property with a private drainage system that retains 100-year storm runoff without discharging to the public system. Both of those are physical conditions a builder can create, not statuses you apply for.
The Metered Half Of The Bill
Five Tiers, One Multiplier, And A Winter Window That Moved
Water is billed on a base charge set by meter size plus consumption in whole thousands of gallons across five rising tiers. Wastewater is a base charge plus a volumetric rate. The rates above took effect on 1 January 2026.
The outside-city column is the part that repays a second look. Nine separate residential lines, two bases and seven volumetric rates, and every one of them is exactly one and a quarter times its inside-city equivalent, rounded to the cent. That is a policy stated as arithmetic rather than as prose, and it holds on the commercial schedule too, where a two inch meter is $170.16 inside and $212.70 outside.
Sewer volume is capped by a winter average, which is a common enough arrangement that we have covered it at length elsewhere and will not rebuild here. Our El Cajon page sets out the mechanism in full and our Flower Mound and Lewisville pages carry the Texas versions. Two Waco-specific details are worth having. If no water is used in the winter months, or the service is new, the average defaults to 6,000 gallons. And if you use less than your average in any month you are billed the lesser figure.
The third detail is a disagreement rather than a rule, and we print it rather than pick a side. The City’s own Utility Rates page gives the winter window as December, January and February in the 2026 block, and as January, February and March in the 2025 block, on the same page. Which months your own average was struck from is a question for the utility office.
Fifty Thousand Service Lines Inventoried, And No Lead Found On Either Side
Under the revised federal Lead and Copper Rule every water system had to inventory the material of its service lines. Waco built a database of over 50,000 of them and published a Service Line Material Map so a resident can look up an address. The result the City reports is a negative one: there are no known lead services within the City system or on the customer side.
A null result is worth stating precisely because most cities cannot state it. It removes one entire class of question from a Waco house. It does not remove the others. The City is explicit that it holds no information at all about the materials used in private plumbing inside homes and businesses, and that a customer who wants to know should hire a licensed plumber to inspect. The boundary it draws is that the City-owned line runs from the main to the property line, and the customer-owned line runs from the property line onward.
The City also publishes the field test, which is the same one a plumber uses and costs nothing to run yourself. Scrape a small area of the pipe with a flathead screwdriver. Copper shows the colour of a penny. Galvanised steel stays a dull grey. Lead scrapes shiny and silver. A magnet holds to galvanised steel and does not hold to copper or lead. Inside an older Waco house the more likely finds are galvanised supply and cast iron waste, and the symptoms of the first are pressure and rust rather than anything you can taste. Our guide to the signs of a hidden water leak covers what failing supply pipe does before it bursts.
Separately, the City runs corrosion control as part of the same rule, raising the pH of the water so that scale forms inside the pipe and less plumbing material dissolves into it. That is a treatment decision with a plumbing consequence: scale that protects a pipe also narrows it, and in a house with original galvanised supply the two effects arrive together. The map is online and the City states it is also available at Waco City Hall, 300 Austin Avenue, and the Central Library at 1717 Austin Avenue.
Your Waste Leaves Waco Under A Seven City Agreement
Waco does not treat its sewage as a city on its own. The Waco Metropolitan Area Regional Sewerage System, which the City abbreviates to WMARSS, serves Bellmead, Hewitt, Lacy Lakeview, Lorena, Robinson, Waco and Woodway from shared facilities, and it operates the interceptors and lift stations as well as the plants.
There are two treatment plants today. The Central Wastewater Treatment Plant sits at 1147 Treatment Plant Road in Waco, and the Bull Hide Creek plant is at 1646 Cooksey Lane in Lorena, which is a different city from the one most of its flow comes from. A third is coming. A 2019 study of the China Spring area sewer basin found growth running ahead of capacity, and the City has bought land on Buster Chatham Road for a future North Brazos plant.
The practical reading for a household is about capacity rather than geography. A basin that a City study has already described as growing past its capacity is a basin where a surcharged main is a live possibility during heavy rain, and where what happens at your own lowest fixture during a storm is worth knowing rather than discovering. Our drain cleaning service is the right call when the symptom is in your own line and our emergency plumbing service is the right one when it is not waiting.
On the collection side the City states the position most plainly on its fats, oils and grease page, and it also runs four free used cooking oil drop-offs: the Cobbs Recycling Centre at 4201 Trice Avenue, open Monday to Saturday 8 to 5, and three sites with twenty-four hour access, the Mount Carmel plant at 5701 Lakeshore Drive, the Riverside plant at 200 Colcord Avenue, and Hawaiian Falls at 900 Lake Shore Drive. Environmental Compliance takes grease questions on (254) 750-5800. Our guide to unclogging a drain without chemicals covers what to do before that becomes a call.
The Rule With Teeth
An Irrigation Fault Is A Disconnection Risk, Not Just A Water Bill
Waco went to mandatory year-round conservation on 1 July 2024, under a Utility Profile and Water Conservation Plan of the same date. The City explains the trigger without drama: the Texas Commission on Environmental Quality requires every supplier serving at least 3,300 connections to refresh its conservation and drought contingency plans every five years.
The schedule is by address parity. Odd numbers water Sunday, Tuesday and Thursday. Even numbers water Monday, Wednesday and Saturday. Nobody waters on Friday, and nobody waters between 10 in the morning and 7 in the evening on any day. Hand watering is defined narrowly enough to matter: a hose or a watering can, and a hose connected to a sprinkler does not count, and the hose has to carry an automatic shutoff nozzle.
The enforcement is where the plumbing risk sits. A fine of up to $2,000 can be assessed for each violation, and three or more violations at one service address inside 30 days can result in the service being discontinued. The City sets one procedural guard against that: a violation has to be observed by at least one City employee before it counts. Reports come in through the MyWaco app or on (254) 299-CITY.
Now consider a stuck irrigation solenoid or a controller with a dead backup battery that reverts to a factory schedule. That is a fault that waters every day, at the wrong hour, in full view of the street, and it can accumulate three observed violations in a fortnight without anybody in the house touching anything. There is a 60-day variance for newly planted grass and landscaping, and athletic fields and golf courses file a mandatory water plan that the Director of Water Utility Services reviews each 1 October.
What Waco Asks For To Open An Account, And Who Can See It Afterwards
The list the City publishes for opening a utility account is longer than most. Valid government-issued identification, a social security number, an employer name and a phone number are ordinary enough. The next three are not. The City also asks for the names of a spouse or roommates, their social security numbers, and their government-issued identification, and adds that further information may be required.
The reason it gives is verification rather than credit. When anyone rings or calls in about the account, including a spouse or a roommate, they are asked to verify one or both of those numbers. The City states that customer information may be reported to a credit agency and may be used by a third-party collection agency contracted to collect delinquent accounts.
There is a confidentiality route and it is worth knowing what it does and does not do. Under the Freedom of Information Act a customer can sign or send a written confidentiality request, after which address, telephone number, social security number and consumption information will not be released. The exceptions named are a consumer reporting agency, other utility companies, and any state or federal government and their subcontractors. Consumption information sits in that list, which is unusual, and it is the line a landlord and tenant dispute over a leak would eventually turn on.
Practically: the account moved to a new portal, at mywacoaccount.com, and the twelve-digit account number on an older bill converts to a new seven-digit one through a lookup on that site. Payment methods and autopay do not carry over by themselves. The drive-through at 425 Franklin Avenue is open weekdays 7:30 to 5:30 and the number is (254) 299-CITY. The City also publishes a warning that it is not affiliated with Doxo.com or any third-party bill payment service, which is a reasonable thing to check before paying anybody.
Waco Compared With The Texas Cities We Have Already Documented
Waco is the seat of McLennan County, roughly halfway between the Dallas and Austin metro areas on Interstate 35, and the City says it supplies water to more than 131,000 people with a service-area population projected to grow by almost 40,000 over 25 years. It is spending against that: the Building Waco capital programme is 320 million dollars over ten years, split 139 million for wastewater, 131 million for water and 50 million for streets.
Set against the other Texas cities on this site the contrast is in what the City asks of you rather than what it charges. Our San Angelo page covers a city that makes a household initial a duty to keep its own plumbing in repair before the water is switched on. Waco does the opposite: it asks the household for almost no undertaking at all and instead measures the property from the air and bills what it finds. Our Palo Alto page in California is the third position again, a city that deems a property occupied from the presence of a meter.
On the fee itself, our Yorba Linda page covers a flat residential sewer charge, which is a different animal from a drainage fee: a flat charge ignores the property, while Waco’s drainage fee measures it in square feet. And an availability charge, which we cover elsewhere, bills a connection that could be made and is not. Waco bills hard surface that exists.
Nearby, our Waxahachie page covers the next city north on the corridor, Austin covers the metro to the south, Abilene covers west central Texas, and the Texas overview covers state licensing and what a Responsible Master Plumber number actually certifies. If the problem is water you cannot see, our leak detection service is the one that finds it, and if it is a fixture rather than a pipe our guide to fixing a running toilet covers the commonest cause of a bill that will not come down.
Plumber Waco TX Questions, Answered From The City’s Own Pages
Everything below is taken from City of Waco material read in August 2026. Where the City publishes a structure without publishing the number behind it, or where it contradicts itself, this page says so instead of filling the gap in.
Because the fee is not a charge for a service delivered to you. The City describes it as a dedicated charge for the public stormwater system, funded in proportion to how much runoff a property generates, and runoff is estimated from impervious cover. The more roof, driveway and paving a parcel carries, the larger the share. It appears on the monthly utility bill and cannot legally be spent on anything except stormwater work.
The metered water and the volumetric wastewater stop. The drainage fee does not, and the City is explicit about it: if a property does not receive a water bill from the City, a separate drainage account will be created regardless of occupancy. Base charges tied to meter size are also not consumption charges. Anyone leaving a Waco property empty during a long repair should expect a bill to keep arriving.
It can, in either direction, and only if it moves you across a band boundary. Single-family bands sit at 500, 1,960 and 3,400 square feet of impervious cover. Inside a band the fee does not move at all. Across the 1,960 line it moves from 0.57 to 1.0 of an Equivalent Residential Unit, which is a 75 per cent rise on that line. The City reads the area from aerial imagery flown roughly every two years, so the change is unlikely to be immediate.
The City reports none. Under the revised Lead and Copper Rule it inventoried over 50,000 service lines and published a Service Line Material Map, and it states that there are no known lead services within the City system or on the customer side. It also states that it holds no information about the materials inside private buildings, and recommends hiring a licensed plumber if you want your own pipework identified.
The City publishes that a fine of up to $2,000 can be assessed for each violation of the watering rules, and that three or more violations at one service address within 30 days can result in service being discontinued. A violation has to be observed by at least one City employee first. A faulty controller or a stuck valve can produce repeat violations without anyone in the house realising, which is why an irrigation fault in Waco is worth fixing promptly rather than at the end of the season.
This is a genuine disagreement in the City’s own published material and we are not going to resolve it for you. The Utility Rates page states December, January and February in its 2026 rate block, and January, February and March in its 2025 rate block. Both appear on the same page. What is consistent is that a new service, or a winter with no water use at all, defaults to 6,000 gallons, and that if you use less than your average in a month you are billed the lesser amount.
Because the City applies a single multiplier rather than a separate schedule. Across the nine residential lines published for 2026, two base charges and seven volumetric rates, each outside-city figure is exactly one and a quarter times the inside-city figure, rounded to the cent. The same holds on the small commercial schedule. It is a policy expressed as arithmetic.
A seven city regional system. The Waco Metropolitan Area Regional Sewerage System serves Bellmead, Hewitt, Lacy Lakeview, Lorena, Robinson, Waco and Woodway, and operates the interceptors, lift stations and two treatment plants: the Central plant on Treatment Plant Road in Waco and the Bull Hide Creek plant on Cooksey Lane in Lorena. A third plant is planned on Buster Chatham Road after a 2019 study found the China Spring basin growing past its capacity.
Only on the published grounds. The City exempts property owned by the United States, the State of Texas, McLennan County, the City itself or any independent school district, tax-exempt religious property, higher education, undeveloped land held in its natural state, closed cemeteries, and single-family housing with no registered motor vehicle, trailer or recreational vehicle associated with the residence. There is an exemption form for qualifying properties. The residential fee is $2.00 a month.
Two City pages that would have been directly relevant are excluded by the City’s own robots.txt and were not fetched: the Water Utility page under Resident, My Home, and the Water Office page under Water Utility Services. The Development Services permits path is also excluded, so no plumbing permit fee is stated anywhere above. The Code of Ordinances was not read, and the appeal form itself was not read, only the City’s description of it.
Every Figure Above, And Where It Came From
The residential and commercial water and wastewater rates, both the 2026 and the 2025 blocks, the winter average description and its 6,000 gallon default, the drainage fee history and exemptions, the ERU definition and bands, the $6.55 rate, the two worked examples, the appeal condition, the street maintenance fee and its exemptions, and the lane mile, bridge and signal counts all come from the City Utility Rates page. The ERU restatement and the municipal code Article X reference come from the Drainage Fee Map page.
The account opening requirements, the privacy statement and its disclosure exceptions, the portal migration and account number conversion, the drive-through address and hours, the payment channels and the third-party payment warning come from Utility Bill. The service line inventory, the null lead result, the City and customer ownership boundary, the corrosion control description and the screwdriver and magnet identification test come from Lead and Water Information, with the map availability at City Hall and the Central Library from the Water Treatment division page.
The seven WMARSS member cities, the two plant addresses, the China Spring basin study and the Buster Chatham Road site come from Wastewater Treatment. The capital programme totals and the service population figures come from Building Waco. The watering day schedule, the hours and the reporting route come from Public Works Utilities, and the hand watering definition, the shutoff nozzle requirement, the $2,000 figure, the three violations in 30 days rule, the observed-by-an-employee guard, the 60-day variance and the TCEQ five year requirement come from the Water Conservation FAQs. The cooking oil drop-off sites and hours come from Fats, Oils and Grease, and the MS4 permit history from Stormwater and MS4 Compliance.
What we could not read, stated rather than guessed at. The City of Waco robots.txt runs to 921 lines and individually excludes seventeen utility paths. Two of them are directly on this subject: the Water Utility page under Resident, My Home, and the Water Office page under Water Utility Services. Both were refused by a per-path check and were not fetched. The Development Services permits path is excluded on the same file, so no plumbing permit fee, inspection fee or tap charge appears above. Those are blanks, not zeros.
The Code of Ordinances itself was not read. Article X and section 26-400 are named above only because the City rate pages name them by number. The drainage fee appeal form was not read, nor was the Wastewater Collection System Master Plan, nor either water quality report. No contaminant figure of any kind appears on this page and none was sought. No office, address, crew, response time, guarantee or coverage claim of ours is stated for Waco, and no testimonial or performance statistic appears above.
Elsewhere on this site, our Texas overview covers state licensing, our El Cajon, Flower Mound and Lewisville pages cover winter averaging in depth, our San Angelo page covers the opposite arrangement where the city makes you sign a maintenance duty first, our Yorba Linda page covers a flat residential sewer charge, and our emergency plumbing service covers what happens when none of this can wait.
