Plumber Round Rock: Five Tiers, One Refund, And A 90 Day Clock
Round Rock meters your water on five tiers and the top one costs about three times the bottom one. It meters your wastewater too. Then, unlike most cities, it offers a way to claw some of a leak back. That refund has conditions, a deadline, and an exclusion list that rules out the two places most residential water actually escapes.
The practical upshot is that in this city the order of operations matters. Fix first, document second, apply third, and do it inside ninety days. This page sets out the published rates, the published adjustment rules, the commercial surcharge mechanism and the backflow clock. All of it comes from City of Round Rock pages, and where the arithmetic is ours the sentence says so.
Why a plumber Round Rock residents call early saves more than the repair costs
The residential water rate is a monthly base fee plus a tiered volume charge, and the tiers climb steeply. Effective 1 November 2025 the City lists 2 dollars 57 cents per thousand gallons for the first 10,000, then 3 dollars 63 cents to 18,000, 4 dollars 70 cents to 26,000, 7 dollars 4 cents to 34,000, and 7 dollars 96 cents above that. The base fee on a standard five eighths inch meter is 18 dollars 21 cents.
Read that as a leak curve rather than a price list. A household sitting comfortably in the first tier pays the cheapest water in the schedule. The same household with an unnoticed fault climbs through the tiers as the month runs, and by the top band each additional thousand gallons costs about three times what the first thousand did. That ratio is our division of two published figures.
The wastewater side is billed separately and on a different basis again. Residential wastewater is a base fee of 14 dollars 91 cents plus 3 dollars 21 cents per thousand gallons, and the City states that residential wastewater usage is determined following its wastewater averaging method rather than from live monthly consumption.
So Round Rock sits between the two other cities we published this week. It averages the sewer side, like El Cajon does, and it meters the water side live and steeply, which Folsom also does. What it does not do is let either side of the bill sleep through a leak.
The City has already published next year, and only the top of the ladder moves
This is the part worth planning around. Alongside the current rates, Round Rock publishes the schedule taking effect on 1 November 2026, and the two tables do not move together. The first tier stays exactly where it is at 2 dollars 57 cents per thousand gallons. Every tier above it rises.
The second tier goes from 3 dollars 63 cents to 3 dollars 86 cents. The third goes from 4 dollars 70 cents to 5 dollars 14 cents. The fourth goes from 7 dollars 4 cents to 7 dollars 71 cents. The fifth goes from 7 dollars 96 cents to 9 dollars 11 cents. By our arithmetic those are increases of roughly 6, 9, 10 and 14 per cent against no increase at all at the bottom, so the rise gets larger the higher up the ladder you are.
Put plainly, and this observation is ours rather than a City statement: a household that uses a normal amount of water will pay the same volume rate next year as this year. A household with a leak will pay measurably more. The gap between the cheapest and the most expensive thousand gallons widens from about 3.1 times to about 3.5 times.
The base fee moves as well, from 18 dollars 21 cents to 19 dollars 12 cents on a standard meter, and residential wastewater volume goes from 3 dollars 21 cents to 3 dollars 28 cents per thousand gallons. Commercial wastewater volume runs 3 dollars 2 cents rising to 3 dollars 13 cents, with commercial base fees set by meter size.
The other two lines on the same bill
Round Rock bills water, wastewater, stormwater, garbage and recycling together through one monthly utility statement, so the leak conversation and the bin conversation arrive in the same envelope. Garbage and recycling is 24 dollars 69 cents a month, collected by Republic Services with garbage weekly and recycling every other week on the same day.
Stormwater drainage is the interesting one because it is not billed on water at all. The residential rate is 6 dollars 75 cents per dwelling unit. The non-residential rate is charged per 2,900 square feet of impervious area, at 6 dollars 9 cents rising to 6 dollars 75 cents, so it prices the concrete and asphalt on a site rather than anything that goes through a pipe.
What the City says happens when it goes wrong
The wastewater pages are unusually blunt and one sentence deserves repeating. The City states that an overflow has to be cleaned up and paid for immediately, and that these expenses are generally not covered by homeowner insurance. That is a warning about an uninsured liability sitting behind a preventable blockage.
It also says its treatment processes are designed to break down bodily waste and toilet paper only, that it removes thousands of pounds of wipes, grease and other problematic material from the system every day, and that wipes labelled flushable belong in the trash. It offers residents a free lid to secure a grease can. Wastewater emergencies run on 512-218-5555, twenty four hours a day.
The leak adjustment, and why the invoice is the claim
Round Rock offers leak adjustments as a courtesy to qualifying customers who experience a leak on the customer side of the meter, and it is explicit that adjustments are based on excess water consumption rather than on the dollar amount. The same page carries the ownership sentence that many cities leave unwritten: leaks on the customer side of the meter, including all repairs and associated costs, are the responsibility of the property owner or tenant.
The conditions are where a plumber matters. The leak must be repaired before the request is submitted. The request must be in writing and must arrive within 90 days of the repair. And proof of repair is mandatory, in the form of a professional plumbing invoice, or receipts for parts and materials where the customer did the work themselves.
That makes documentation part of the job rather than an afterthought. A repair with no paperwork is a repair with no claim, and a verbal quote is not evidence. If you are having work done in Round Rock, the invoice is worth as much as the fix in the month a leak has already run.
Two limits cap what comes back. Only one leak adjustment is permitted per account within 12 months, and adjustments are limited to one month of the leak period however long the fault actually ran. The City also asks customers to keep paying while the request is under review, warning that missed payments may result in service interruption, and allows up to 30 days to process once all affected bills have been generated.
- Repair before you apply. The City requires the leak to be fixed before a request is submitted. Applying first and fixing later is the wrong order and it does not qualify.
- Get an itemised invoice. Proof of repair is mandatory. A professional plumbing invoice satisfies it. If you do the work yourself, keep every parts and materials receipt, because that is the only alternative the City names.
- Start the 90 day clock from the repair, not the bill. The window is measured from when the leak was repaired, so a slow billing cycle eats into it rather than extending it.
- Check whether your leak is even eligible before you plan around a refund. Excessive irrigation, broken sprinkler heads, badly programmed irrigation schedules, pool leaks, pool auto refill systems, a hose left running and meter tampering are all excluded.
- Budget as though only one month comes back. Adjustments are limited to one month of the leak period, so a fault that ran through three billing cycles is not refunded three times over.
- Do not stop paying while you wait. The City asks customers to continue monthly payments during review and warns that failing to do so may interrupt service. Financial hardship is handled through Utility Billing, not by withholding.
- Remember it is once a year. One adjustment per account in any 12 month period, so a second leak in the same year is on you. That is an argument for finding the cause rather than only the symptom.
If you run a business here, your wastewater is sampled and priced by the pound
Round Rock operates a surcharge programme under Chapter 44, Article VI, Section 44-149 of the City Code of Ordinances, applying to all nondomestic dischargers to the Brushy Creek Regional Wastewater System. Its stated purpose is to reduce excess solids and oxygen demanding substances entering the system, which the City links directly to clogged lines, sanitary sewer overflows and load on the treatment plant.
The mechanism is specific. Once per year City sampling personnel collect a composite sample of the wastewater discharged from the facility and analyse it for total suspended solids and for either biochemical or chemical oxygen demand, using the American Public Health Association standard methods.
The pricing runs off thresholds. Biochemical oxygen demand above 250 milligrams per litre is charged at 47.7 cents per pound. Chemical oxygen demand above 450 milligrams per litre is charged at 22.7 cents per pound. Total suspended solids above 250 milligrams per litre are charged at 47.7 cents per pound. Average flow from the business and a lab fee complete the calculation, and the lab fee applies only where a threshold has been exceeded.
Below those thresholds there is no surcharge at all, which turns grease control into a billing question as well as a maintenance one. Once a surcharge is calculated a notification goes to the water meter owner, who then has fourteen days to inquire about or contest the charge. Once it appears on the water bill it must be paid.
Backflow, and the longest testing clock we have found
The backflow programme is administered on the City behalf by an external provider rather than in house. Residential properties with irrigation systems, pools or fire sprinkler systems are required to have a backflow prevention device, and the City notes these are typically located by the curb in a separate box beside the water meter box, which is a useful pointer for anyone who has never looked.
The testing process puts the arrangements on the customer. The City sends notifications 30 days before the testing due date. The customer then hires a registered backflow tester and gives them the customer confirmation number from the notice. The tester performs the test, submits the report through the online tracking system, and pays 12 dollars 95 cents per test report submitted.
One interval stands out. The City states that backflow devices on residential fire sprinkler systems without added chemicals are required to be tested once every seven years. Every other backflow regime we have documented, including Folsom published earlier this week, runs on an annual cycle, so a seven year clock is a genuine outlier and easy to forget between tests.
The City explains why any of it matters in plain terms: backflow is the reverse flow of water into the public supply, which can happen when a main breaks and the drop in pressure creates a suction effect, drawing whatever sits on the customer side of the connection back toward the drinking water system.
How Round Rock compares, and who to call
Three cities we published this week answer the same question three different ways, and the plumbing advice changes with the answer. El Cajon prices household sewer from a five month winter water average, multiplies it, and puts the result on a property tax bill. Folsom charges a flat monthly sewer amount per dwelling with no volume element at all, so a leak cannot touch that bill. Round Rock meters both sides and stacks five steep tiers on the water.
Closer to home the picture is different again. Our Austin and Pflugerville pages set out their own rate structures and permit rules, and sharing a metro area does not mean sharing a utility policy. Round Rock runs its own utility, its own surcharge ordinance and its own adjustment programme.
On the private side of the meter the work is ordinary plumbing with unusually good paperwork incentives. Leak detection finds the fault while it is still inside one billing period. Sewer line repair covers the lateral, drain cleaning covers blockages, and emergency plumbing covers out of hours.
Plumber Round Rock: the questions a five tier rate creates
Answers built only from what the City of Round Rock publishes. Where we have done arithmetic on published figures, the sentence says so.
The residential rate is a monthly base fee plus a five tier volume charge. Effective 1 November 2025 the base is 18 dollars 21 cents on a standard five eighths inch meter, and the volume rate runs 2 dollars 57 cents per thousand gallons to 10,000, 3 dollars 63 cents to 18,000, 4 dollars 70 cents to 26,000, 7 dollars 4 cents to 34,000, and 7 dollars 96 cents above that. Residential wastewater is a separate base fee of 14 dollars 91 cents plus 3 dollars 21 cents per thousand gallons.
Some of them. The City publishes a 1 November 2026 schedule alongside the current one, and the two do not move together. The bottom water tier stays at 2 dollars 57 cents while the tiers above it rise to 3 dollars 86 cents, 5 dollars 14 cents, 7 dollars 71 cents and 9 dollars 11 cents. By our arithmetic that is roughly 6, 9, 10 and 14 per cent, so the increase is larger the higher the tier. The base fee also rises to 19 dollars 12 cents.
Possibly. The City offers leak adjustments as a courtesy to qualifying customers with a leak on the customer side of the meter, based on excess water consumption rather than on the dollar amount. You must repair the leak first, apply in writing within 90 days of the repair, and supply proof of repair. Only one adjustment is permitted per account within 12 months and it is limited to one month of the leak period.
The City names two forms. A professional plumbing invoice, or receipts for parts and materials if you completed the repair yourself. There is no third option listed, which effectively means an undocumented repair cannot be claimed. If you are having work done and think you may apply, ask for an itemised invoice at the time rather than trying to reconstruct one later.
The published exclusion list covers excessive irrigation use, broken irrigation heads, incorrectly programmed irrigation schedules, pool leaks, pool auto refill systems, a hose left running, and water loss resulting from meter tampering. Between them those rule out most outdoor water loss, so in practice the adjustment is aimed at indoor plumbing faults.
You do, and Round Rock says so directly. Its leak adjustment page states that leaks occurring on the customer side of the meter, including all repairs and associated costs, are the responsibility of the property owner or tenant. That is a clearer statement of the boundary than many cities publish, and the adjustment programme is a partial credit on consumption rather than any contribution toward the repair.
Through the surcharge programme under Chapter 44, Article VI, Section 44-149, which applies to all nondomestic dischargers to the Brushy Creek Regional Wastewater System. City personnel take one composite sample a year and test it. Biochemical oxygen demand above 250 milligrams per litre is charged at 47.7 cents per pound, chemical oxygen demand above 450 at 22.7 cents per pound, and total suspended solids above 250 at 47.7 cents per pound, plus average flow and a lab fee. Below the thresholds there is no surcharge.
Yes, but the window is short. Once a surcharge is calculated the City sends a notification to the water meter owner, who then has fourteen days to inquire about or contest the charges. The City states that once the surcharge appears on the actual water bill the fee must be paid, so the time to question it is on receipt of the notification rather than on receipt of the bill.
It depends what it protects. The general programme runs on notification, with the City sending notice 30 days before the due date through its external administrator, after which you hire a registered tester and supply your customer confirmation number. But the City states that backflow devices on residential fire sprinkler systems without added chemicals are required to be tested once every seven years, which is a much longer interval than the annual cycle most cities use.
The City warns that it generally does not. Its wastewater page states that an overflow is a costly mess that has to be cleaned up and paid for immediately, and that these expenses are generally not covered by homeowner insurance, listing property damage, plumbing problems, cleanup, replacement of goods and health issues among the consequences. Check your own policy, but treat prevention as the cheaper option.

Every water, wastewater, stormwater and garbage rate quoted above, both the 1 November 2025 and the 1 November 2026 schedules, the five residential water tiers and their boundaries, the base fees, the residential wastewater base and volume rates, the commercial wastewater volume rates, the statement that residential wastewater usage is determined following the wastewater averaging method, the stormwater residential rate per dwelling unit and non-residential rate per 2,900 square feet of impervious area, and the garbage and recycling charge collected by Republic Services, come from the City of Round Rock Water, Sewer and Garbage Rates page.
The leak adjustment programme in full comes from the City of Round Rock Leak Adjustment Requests page: that adjustments are a courtesy to qualifying customers and are based on excess consumption rather than dollar amount, that leaks on the customer side of the meter including all repairs and associated costs are the responsibility of the property owner or tenant, the requirement to repair first, the 90 day written request window, the mandatory proof of repair by professional plumbing invoice or parts receipts, the one adjustment per account per 12 months limit, the one month cap on the leak period, the instruction to keep paying during review, the up to 30 day processing time, and the full ineligibility list.
The surcharge programme details come from the City Surcharge and Grease Program page: the ordinance citation, the application to all nondomestic dischargers to the Brushy Creek Regional Wastewater System, the annual composite sample, the American Public Health Association standard methods, the per pound rates and their milligram per litre thresholds, the average flow and lab fee components, the statement that below the thresholds there is no surcharge, and the fourteen day window to contest.
The backflow arrangements, including the external administrator, the requirement for devices on residential properties with irrigation systems, pools or fire sprinkler systems, their typical location by the curb beside the meter box, the 30 day advance notification, the customer confirmation number process, the 12 dollar 95 cent per report fee paid by the tester, the seven year interval for residential fire sprinkler devices without added chemicals, and the explanation of backflow itself, come from the City Backflow Prevention page. The overflow warnings, the insurance statement, the treatment design note, the daily removal of wipes and grease, and the free grease can lid come from the City Wastewater page.
The arithmetic in this page is ours and is labelled as ours in the copy as well as here. That the top water tier is about 3.1 times the bottom tier this year and about 3.5 times next year is our division of the published rates. That the tier increases are roughly 6, 9, 10 and 14 per cent is our comparison of the two published tables. And the observation that the bottom tier is held flat while every tier above it rises is ours: the City publishes both tables but does not characterise the pattern. None of these appears on any City page.
Refused and left blank rather than estimated: water hardness and every drinking water quality value, because no constituent figure appears on the pages read and the annual water quality report was not opened; all plumbing permit and inspection fees; the commercial water and wastewater base fees, because those tables are keyed to meter size and the meter size rows were not captured, so only volume rates are quoted; the Brushy Creek Regional Wastewater Treatment Plant capacity and the cost of its expansion; the lab fee amount in the surcharge calculation, which the City names without pricing; and any count of sewer miles, manholes, laterals or lift stations, none of which is published on the pages read.
Where the City says it removes thousands of pounds of material from the system every day, that is quoted as its own phrasing and is not converted into an annual tonnage by us. No sanitary sewer overflow count is stated. No office, address, crew, response time, guarantee or coverage claim of ours is stated for Round Rock, and no testimonial or performance statistic appears anywhere above. Rates, ordinances and programmes change, so confirm current requirements with City of Round Rock Utility Billing or Utilities and Environmental Services before relying on anything here.
