High Water Bill in Horizon City, TX 79928

Confirm the account and water provider

The Town of Horizon City lists Horizon Regional Municipal Utility District for water and sewer, but the name of the town or ZIP on a mailing address is not enough to establish the provider. Begin with the utility name, service address, meter number and account class printed on the bill. If the bill is not available, use the Texas Water Development Board boundary viewer as a starting point and confirm the result with the utility.

This matters because provider rules, meter sizes, in-district or out-of-district status and wastewater calculations can change the amount due. A nearby utility’s rates or leak policy should not be applied to an HRMUD account. The Horizon City water-provider and plumbing context explains the geography in more detail.

Read the HRMUD bill before assuming a hidden leak

Lay the current statement beside at least one earlier bill. Compare the service dates, number of days, beginning and ending meter readings, billed gallons, water charge, wastewater charge, trash or other listed items, and any late or convenience fees. The useful comparison is not only this month’s total against last month’s total. It is use per day across similar periods.

A family visit, irrigation, a new pool fill, more laundry, a running toilet or a longer billing period can raise measured use. A new rate order or a different account classification can change the dollar amount even when use looks similar. If the statement shows an estimated reading, an adjustment or another notation you do not understand, ask HRMUD to explain that account entry before opening walls or paying for leak detection.

1. Compare billed days.Thirty-five days should not be compared casually with a twenty-eight-day statement.
2. Compare measured gallons.Calculate approximate gallons per day to normalize unequal billing periods.
3. Separate charges.Water, wastewater, trash, fees and payment costs should not be treated as one usage number.
4. Confirm meter and account class.The published schedule differs by meter size and district status.
5. Write down the question.Ask about the exact line, reading or classification that does not make sense.

Match the bill to what happened during those service dates

A bill investigation becomes clearer when the dates are treated as a timeline. Mark travel, guests, school breaks, irrigation changes, landscaping, a pool fill, appliance replacement, toilet repairs and any period when the property was vacant. Then compare those events with the start and end of the billed period. A change that occurred after the meter-reading date belongs to the next statement, not the one in hand.

Weather can change outdoor use, but a general statement such as “it was hot” is not enough. Note the irrigation schedule, number of zones, visible overspray and whether an automatic system ran. If an outdoor line was repaired, record the date and the meter reading before and after. The same approach applies indoors: note a running toilet, a guest stay, more laundry or a water-using appliance cycle.

Keep the comparison in gallons. Dollar totals can be affected by rate tiers, fees and separate services. Gallons per day provide a more stable starting point when billing periods are unequal. If the timeline explains the increase and the no-use meter check is still, continue monitoring. If the timeline does not explain the increase and the meter changes during a controlled test, move to fixture and leak checks.

How residential wastewater charges enter the bill

HRMUD’s Services & Rates page states that residential wastewater charges are computed using the lesser of the current monthly water use or the customer’s average metered use for the preceding December, January and February. For a residential customer without that winter history, the page states that the calculation uses current monthly use or 3,000 gallons, whichever is less. The signed rate order effective July 23, 2026 is the controlling source reviewed with the web page.

This method is important when a homeowner asks why the water and wastewater portions do not move together in an obvious way. It also explains why account history matters. The guide does not calculate a bill because meter size, district status, account history and other charges can change the result. Use the current statement and ask HRMUD for an account-specific explanation.

Do not infer a leak from the wastewater line alone. First determine whether measured water use changed, how the wastewater basis was selected and whether the bill includes other items. If actual use rose, continue to the no-use meter test and fixture checks.

Run a no-use meter check

EPA WaterSense recommends a simple comparison across a period when no water should be used. Choose a time when toilets, faucets, appliances, irrigation, water treatment equipment, pool autofill and every other water-using device can remain off. Note or photograph the meter reading. Wait about two hours without intentional water use, then compare the reading again.

A changing reading during a true no-use period supports more investigation, but it does not locate the source. A toilet may cycle intermittently. Irrigation or an automatic device may run without being noticed. A meter display can also be misunderstood. Repeat the check if the conditions were not controlled, then inspect common uses before deciding that the leak is concealed.

If the meter is in a hazardous area, a locked enclosure or somewhere you cannot access safely, do not force access. Ask the provider about the reading or use a qualified professional.

Check common indoor sources

Start with toilets because a faulty seal or fill cycle can pass water without leaving a puddle. Listen after the flush should have ended. Look for water entering the overflow tube. A dye check can show whether tank water reaches the bowl without a flush. The running-toilet guide explains these observations in more detail.

Next, inspect faucets, under-sink supply connections, appliance hoses, the water heater area and any accessible pipe runs. Look for a fresh drip, damp cabinet base, stain, swollen material, recurring fill sound or water near a drain pan. Do not loosen fittings to search for a leak. Do not open a wall or equipment panel simply because the bill is high.

When there is no visible source but the no-use meter check still changes, use the full hidden-water-leak checklist. That general guide owns the diagnosis. This local page keeps its focus on HRMUD billing, the order of checks and the point at which account evidence becomes a plumbing question.

Check outdoor and automatic water use

Walk the property without entering unsafe or restricted areas. Check hose bibs, attached hoses, irrigation valves, sprinkler heads, wet soil, pooling water and unusually green strips. If the home has a pool, spa, evaporative cooler, water-treatment backwash or automatic refill, include it in the review. A timer may operate when nobody is watching.

Separate an expected seasonal increase from unexplained continuous use. Irrigation can account for a large change and still require repair if a valve sticks or a buried line leaks. The important question is whether the use was intended, whether it stops when scheduled equipment is off and whether the meter continues to change during the controlled no-use period.

Keep a short evidence packet

A useful call to the provider or a plumber begins with the same basic record. Keep the current bill, one or two prior bills, photos of the meter readings, the start and end time of the no-use test, a list of automatic devices that were disabled, and notes about visible fixture or irrigation behavior. Add a simple sketch of where moisture or sound appears if a possible leak is involved.

This packet prevents two common problems. First, it keeps a billing question from becoming an unsupported leak diagnosis. Second, it gives a professional enough context to decide whether the next step is a fixture repair, irrigation review, concealed-leak investigation or a provider clarification.

Do not post a full bill, account number, meter identifier or home access details on social media or a public forum. Share private account information only through a verified provider or professional channel.

Does the evidence point to use, billing or a possible leak?

When to contact HRMUD

Contact HRMUD when the question concerns the billed reading, meter number, account class, rate schedule, wastewater basis, payment status, provider boundary or an active service alert. Keep the statement and your notes in front of you. Ask about the exact reading or charge rather than asking the provider to diagnose interior plumbing.

Separate the questions before making contact. One question may concern whether the meter reading on the statement matches the provider’s record. Another may concern which rate or wastewater method applies to the account. A third may concern water that continues to move at the property. The first two belong with the provider. The third becomes a plumbing investigation after intentional and automatic uses have been controlled.

Record the date of the call, the specific item discussed and any next step the account representative gives. If a corrected reading, field check or additional document is offered, ask how and when it will appear. Do not interpret a request for more account information as confirmation of a leak, and do not assume that a possible leak changes the bill unless HRMUD confirms a current policy for that account.

The web page reviewed on September 17, 2026 contains more than one payment-phone block. Use the contact information printed on the current bill or verify the current contact route on HRMUD’s site instead of relying on a copied number in this guide.

When a plumber may make sense

Professional help may be appropriate when the meter continues to change with controlled uses off, water damage is visible, a shutoff does not work, the likely source is concealed, irrigation or service piping is inaccessible, or a fixture cannot be isolated safely. Water near electrical equipment, a bulging ceiling or rapidly spreading damage is an urgent safety problem.

Share observations, not a guessed diagnosis. The bill comparison, no-use test times, meter photos and list of devices that were off can help a plumber decide whether to start with a toilet, irrigation, an appliance connection or concealed-leak testing. If the meter stayed still and the issue is only a charge or classification, resolve that account question before authorizing exploratory plumbing work.
