Sewer Line Repair in Williamson County, TX

• Service covers Round Rock and Georgetown along I-35 and Hutto and Taylor near SH 130.
• Rules quoted here come from Round Rock, Georgetown and Brushy Creek MUD. Cedar Park, Leander, Hutto and Taylor answer their own utility and permit questions, and a few Williamson addresses sit inside Austin's city limits.
• Coverage for a specific address must be checked before anyone is scheduled.

• Finding the wye on a Brushy Creek MUD dual service to settle whose section failed
• Camera inspection after Round Rock's collections crew has cleared the City side
• Adding or repairing a Georgetown cleanout on the customer side of the dividing line
• Septic house-line and tank repairs on unincorporated or ETJ lots under a county OSSF application
• Trenching where a shallow limestone layer is struck along the route

• Georgetown's construction fee schedule lists individual electrical, HVAC and plumbing trade permits at $50 plus a $10 technology fee.
• The same Georgetown fee schedule charges $50 plus $10 for re-roof, water heater and foundation repair permits, a useful comparison when foundation work disturbs a lateral.
• Method: these are published City fee schedule amounts; contractor labor is priced per linear foot and by depth, and the property line or easement edge is where Georgetown's utility responsibility ends, so the local private run sets the bid.
• Single or dual service. Brushy Creek MUD makes the homeowner responsible from the main on a single service but only after the wye on a shared one, which changes how much pipe a contractor has to replace.
• Hard rock. NRCS places the Georgetown soil series, whose type location lies about a mile from the county courthouse, over indurated Edwards limestone at 20 to 40 inches; where a trench reaches rock, ask how that excavation is priced.
• County septic review. Modifying a system, whether repairing or enlarging it, requires an application through the county's online portal before work starts.

• Georgetown's utility service agreement defines the wastewater point of delivery as the customer's property line or easement edge, and its fee schedule sets the trade permit at $50 plus $10. Round Rock inspects private plumbing under the 2024 International Plumbing Code.
• Step 1: identify your utility (Round Rock, Georgetown, Brushy Creek MUD or another). Step 2: camera the line to the property line or wye. Step 3: pull the city plumbing permit. Step 4: pass inspection; septic parcels apply to the County instead.
• Round Rock lists the 2024 International Plumbing Code among its currently adopted codes; questions go to the Building Inspection desk at 512-218-5550. Its Utility Criteria Manual has private plumbing that connects to City water or wastewater inspected by the Building Inspection Division.
• Williamson County's Engineer's Office is TCEQ-authorized to run the OSSF program under 30 TAC Chapter 285 and the County Engineer's OSSF rules. It no longer accepts email or paper applications; call 512-943-3330 to confirm whether a property needs one. For any plumbing company, ask for the Responsible Master Plumber and look up that license on TSBPE's search.

• TCEQ's Edwards Aquifer rules in 30 TAC Chapter 213 name Williamson among the counties the aquifer trends through and define the recharge zone from official maps of outcrops, caves, sinkholes, faults and fractures. The chapter also defines a private service lateral; if your parcel is mapped there, ask TCEQ's Austin regional office whether any requirement reaches the repair.
• Ask the City which applies at your lot before deciding where a repair stops.
• By the Census Bureau's 2024 ACS count, 49,415 housing units in Williamson County, 17% of 283,983, were built before 1990, and 5,314 were built before 1960. With most of Williamson County's homes newer than that, PVC laterals are common, and failures more often trace to settling, bellied runs or roots at joints than to corroded cast iron.
• Limestone and caliche west of I-35 and Blackland clay soils east of it shape trench cost, and tree roots and settled joints show up in older homes in neighborhoods of central Georgetown and Taylor.
