Flooding in Round Rock, TX: Who to Call First

Round Rock's emergency line for water, wastewater and stormwater problems is 512-218-5555, but part of the city is served by a MUD with its own contacts instead.

Round Rock's Emergency Line for Water, Wastewater and Stormwater

Round Rock Utilities is the first call for a water, wastewater or stormwater emergency at a city-served address. The single number below covers all three categories, so you do not need to guess which department handles a burst pipe, a sewer backup or street flooding.

If a MUD Serves Your Address Instead

Not every Round Rock-area address gets water and wastewater service from the city. Fern Bluff Municipal Utility District and Brushy Creek Municipal Utility District serve parts of the area, and their wastewater connects into the regional Brushy Creek Regional Wastewater System alongside parts of Cedar Park, Leander and Austin.

  • Check a recent water bill first — the provider's name and phone number are printed on it.
  • Your water bill will show your actual provider and its phone number — check it if you are unsure whether the city or a MUD serves your address.
  • A phone number found online for the Fern Bluff MUD may reach its community center, not an emergency line — confirm the district's current emergency number on your water bill.

When in doubt, calling Round Rock Utilities at 512-218-5555 is still a reasonable first step; the city can tell you whether your address is on its system.

Checking Your Flood Zone

Round Rock's Floodplain Administrator, Catalina Arboleda Gonzalez, P.E., CFM, handles questions about whether a specific address sits in a mapped floodplain. Email floodplain@roundrocktexas.gov or call 512-218-7041; the city's Stormwater Division at 512-218-7046 handles broader drainage questions.

  • Floodplain Administrator (address-specific questions): 512-218-7041.
  • Stormwater Division (general drainage questions): 512-218-7046.
  • Williamson County Floodplain Management (unincorporated county addresses only, not inside Round Rock): 512-943-3330.

Inside Round Rock's city limits, the city has floodplain jurisdiction, not Williamson County. The county's floodplain office is for addresses in the unincorporated parts of the county.

Details on the county-level program, for addresses outside any city's limits, are on Williamson County's floodplain management page. Our about page explains how this site researches and checks the numbers on it.

Turning Off Your Water in Round Rock

Use your home's main shut-off valve if you can reach it safely and it turns easily. Do not force a valve you cannot operate; seek qualified help. If you cannot shut off the water yourself, call Round Rock Utilities at 512-218-5555 for help.

  • Locate the main shut-off valve before an emergency happens, so you are not searching for it while water is spreading.
  • If the valve will not turn, stop trying and call for help instead of forcing it.
  • For a MUD-served address, the district on your water bill is the right contact if the main valve is not solving the problem.

Round Rock Rebuild Permits

Round Rock requires a building permit for construction, installation, alteration, repair, movement, demolition or replacement of electrical, gas, mechanical or plumbing systems. Water-damage repairs often touch one of those systems, so check before work starts rather than after.

  • Building Inspection Division: 512-218-5550.
  • If you are not sure whether your repair counts as cosmetic work, the city asks that you call and ask.

A ceiling that took on water from a roof or upstairs leak has its own permit and safety questions — see our ceiling leak water damage guide for Round Rock for that situation specifically.

Flood History and Storms in the Area

The National Weather Service includes the Austin region, which covers Williamson County and Round Rock, in what it calls Flash Flood Alley. Brushy Creek is a documented flood-risk waterway for Round Rock, according to the city's floodplain mapping.

  • In July 2025, Williamson County issued a disaster declaration after severe flash flooding in the county.
  • Winter Storm Uri, in February 2021, caused widespread frozen and burst pipes across Texas, including Central Texas.
  • Neither event is a substitute for checking your own address against the city's current floodplain map.
  • The Upper Brushy Creek Water Control and Improvement District models the watershed and plans flood-control projects across the Brushy Creek basin in Williamson County, alongside the city’s own floodplain mapping.
  • The region also has real-time flood tools, including LCRA’s Hydromet network of river and rainfall sensors, though these supplement rather than replace checking your address against the city’s official floodplain map.

For the county's own account of the July 2025 event, see Williamson County's flood recovery page. Materials that hold moisture after any of these events can develop mold within 24 to 48 hours, according to FEMA guidance — see our mold after water damage guide for Round Rock for the licensing and insurance rules that apply once mold is part of the picture.

If That Did Not Work

If 512-218-5555 does not resolve an active emergency, or you are not sure the city is even your provider, try these routes instead. There is no fixed timeline for any of these options.

  • Call again and ask directly whether your address is served by the city or by a MUD.
  • Check your most recent water bill for a different provider's name and phone number.
  • For a non-emergency floodplain or permit question, use the Floodplain Administrator (512-218-7041) or Building Inspection (512-218-5550) instead of the emergency line.

For the first steps to take before any of these calls, and for what to expect on an insurance claim once the water is stopped, see our Round Rock water damage overview.

Frequently Asked Questions

How do I know if my address is in a flood zone?
Contact Round Rock's Floodplain Administrator at 512-218-7041 or floodplain@roundrocktexas.gov with your address. Inside city limits, the city — not Williamson County — has floodplain jurisdiction, so start with the city even if you have seen county floodplain information online.
Which Round Rock office handles floodplain administrator questions?
Catalina Arboleda Gonzalez, P.E., CFM, is Round Rock's Floodplain Administrator. She can be reached at floodplain@roundrocktexas.gov or 512-218-7041 for questions about whether a specific address sits in a mapped floodplain.
What does the city's water, wastewater and stormwater emergency line cover?
The single number, 512-218-5555, covers water emergencies, wastewater emergencies and stormwater emergencies for city-served addresses. You do not need to identify which of the three applies before calling — the city routes it from there.
My neighborhood is in a MUD — who do I call for a water or sewer emergency there?
Check your water bill for the district's name and current emergency number. Fern Bluff MUD and Brushy Creek MUD serve parts of the area; the community-center number sometimes found online for Fern Bluff MUD is not an emergency contact.
Should I try to shut off my own water before help arrives?
Use the main shut-off valve if you can reach it safely and it turns without force. If it is stuck or you cannot find it, stop and call Round Rock Utilities at 512-218-5555, or your MUD's emergency number, instead of forcing anything.
Is there a county number I should call instead of the city?
Not for an address inside Round Rock's city limits — the city holds floodplain jurisdiction there. Williamson County's floodplain office at 512-943-3330 is for addresses in the unincorporated parts of the county, outside any city's limits.
What is the difference between the utility billing number and the emergency line?
512-218-5460 is Round Rock's utility billing line, for account and payment questions. 512-218-5555 is the maintenance and repair line for an active water, wastewater or stormwater emergency.
