High-bill cause |
Fast check |
What to ask Round Rock |
|---|---|---|
Continuous flow alert | Open MyMeter and check hourly use for the last 24 hours. | Does usage appear every hour, and when did it begin? |
Toilet leak | Use dye tablets or food coloring; check if color enters bowl without flushing. | Can I pick up dye tablets at Utility Billing? |
Meter movement | Turn off all indoor/outdoor water and watch meter for several minutes. | Does the meter show flow when all fixtures are off? |
Main line leak | Check between meter and house; leaks may not pool because local limestone is porous. | Can 512-218-5555 check whether the leak is in the meter box or City side? |
Irrigation overuse | Compare usage with watering days, sprinkler run time and water tier. | Can I schedule a free irrigation checkup or rebate review? |
Water softener issue | Check regeneration cycle and bypass softener temporarily if needed. | Is usage occurring at regular overnight intervals? |
Low pressure | Check PRV, meter area and whether neighbors are affected. | City can help locate PRV but cannot adjust or replace it. |
No water | Verify account status first; unpaid bills may cause shutoff and a doorhanger. | If account is current, ask whether a main break, construction, frozen pipe or private leak shutoff occurred. |
High tier cost | Compare usage against residential tiers; higher gallons cost more per 1,000 gallons. | Which tier did my highest usage fall into? |

Water Quality, Source Water, Lead, Reuse and Wastewater System
Superior rating
Round Rock states its water system is rated “superior” by TCEQ.
2026 quality update
The 2026 release says the annual report shows drinking water met or exceeded federal and state standards.
Water sources
Round Rock uses groundwater and surface water, including Edwards Aquifer wells and Lake Travis water through BCRUA.
Water-quality topic |
Official context |
Best user action |
|---|---|---|
Consumer Confidence Report | EPA requires annual CCR; Round Rock links current and prior reports. | Use current report before making safety claims. |
2026 report update | City says the water system was tested for up to 97 federally regulated constituents and met/exceeded federal and state standards. | Open the 2025 CCR for exact contaminant tables. |
TCEQ rating | Round Rock says the water system is rated “superior,” TCEQ’s highest rating. | Use TCEQ Drinking Water Watch for regulatory records. |
Lead service lines | City states it does not have lead service lines or lead piping in its distribution system; homes built before 1986 could have lead in home plumbing. | Use test swabs or commercial lab testing if concerned. |
Groundwater | Groundwater comes from wells drilled into Edwards Aquifer and usually provides a smaller portion of supply. | Useful for explaining hardness/source questions. |
Surface water | Round Rock partners with Cedar Park and Leander in BCRUA to access Lake Travis water, contracted through LCRA. | Use during drought/source-water explanations. |
Water plant capacity | City says its water plant can treat 65 million gallons per day. | Use for system-scale context, not individual billing. |
Reuse water | Round Rock has irrigated with reclaimed/recycled/reuse water since 1998 and continues expanding reuse where practical. | Do not confuse reuse irrigation with potable residential water unless account specifically has reuse service. |
Wastewater system | Brushy Creek Regional Wastewater System serves regional customers; Round Rock oversees over 450 miles of local collection lines and 12 lift stations. | Report sewer backup quickly and avoid flushing wipes/grease. |
Flushable wipes | City says wipes, grease and other materials clog equipment and increase system costs. | Trash wipes and collect grease instead of using drains. |
Local Notes: Round Rock, MUDs, Republic Services, Stormwater and Utilities
Local issue |
Why it matters |
Best next step |
|---|---|---|
City vs MUD provider | Round Rock serves water in and around the city, including several MUDs outside city limits, but provider boundaries can vary. | Check your bill/provider and the City service-area map before paying. |
Combined bill | Utility bill can include water, wastewater, stormwater drainage, garbage and recycling. | Separate line items before disputing the “water bill.” |
Republic Services | Residential garbage/recycling curbside collection is provided by Republic Services and billed through City of Round Rock. | Call 512-255-4980 for curbside collection concerns. |
Stormwater charge | Stormwater fee is based on drainage/impervious area concepts and can be billed even if property does not receive other City utilities. | Do not treat stormwater as water-gallon usage. |
Gas | Round Rock new-resident guide lists Atmos Energy for gas service. | Do not call Utility Billing for gas account activation. |
Electricity | Oncor delivers electricity; residents choose electric provider for billing. | Use Power to Choose/retail provider for electric bill. |
Water hardness | Round Rock leak tips page lists average hardness around 221 mg/L or 12.9 grains per gallon. | Use this for softener settings or hardness questions. |
Backflow / PRV / cutoff valve | Some issues are on private plumbing; City may help locate valves but cannot adjust/replace PRV. | Call 512-218-5555 for location help, then plumber for private repair. |
Chlorine rinse timing | Free chlorine rinse Aug. 3-Sept. 3, 2026 can cause chlorine odors or cloudy/discolored water. | Check City rinse notice before requesting emergency response for taste/odor alone. |
