Replacing a water heater in Sonterra.
Williamson County has no home plumbing permit for unincorporated Sonterra, but lots inside Jarrell's city limits fall under Jarrell's contractor and code rules. Oncor delivers power. Sonterra is a planned subdivision east of I-35, just southeast of downtown Jarrell, built out since the mid-2000s. Its own municipal utility district (MUD), not a city, runs the water system, which now mixes Brazos River surface water it buys with district wells.
Sonterra is an unincorporated community in Williamson County, so county offices handle permits.

0%Built before 1980
77%Owner-occupied
1%Heat with utility gas
94%Single-family homes
About 83% of homes were built since 2010, so many original water heaters are reaching the age when replacement planning makes sense.
94% of homes heat with electricity, which usually means an electric water heater. It’s worth getting a price on a heat pump model too.
U.S. Census Bureau, American Community Survey ACS 2024 5-year ↗ (2020-2024). Heating fuel is what homes use to heat the house. It often, but not always, matches the water heater’s fuel.
LOCAL CONDITIONS
What’s different in Sonterra.
A MUD that crosses the Jarrell city line
The Legislature created the Sonterra Municipal Utility District in 2005 for land partly inside Jarrell's city limits, partly outside, and partly in the area just outside the city (ETJ), to serve new homes and businesses. A 2009 filing described about 1,458 acres, roughly between FM 487, County Road 315 and I-35, with sewage going to the City of Jarrell's regional plant. Which side of the city line your lot is on decides whether any local permit rules apply.

Brazos River water plus district wells
EPA's drinking water records list Sonterra MUD as a surface water system serving about 16,600 people through some 9,200 connections. Its main supply is treated Brazos River Authority water bought through the Lone Star Regional Water Authority, backed up by district wells off CR 313 and CR 3001 and an emergency well water connection with Jarrell-Schwertner WSC. Because the mix can change, the minerals in your tap water aren't constant. We couldn't find a hardness number from the district, so test your water before choosing a softener or tankless heater.

Inside Jarrell, contractors register with the city

They must follow the city's 2018 International Plumbing Code and 2018 Fuel Gas Code. Lots in the unincorporated part of the MUD have no county home plumbing permit, but state plumbing licensing still applies.

COMMON QUESTIONS
Sonterra water heater questions.
Who supplies water to Sonterra?
Sonterra Municipal Utility District. Its main source is treated Brazos River water bought through the Lone Star Regional Water Authority, plus district wells.
Do I need a permit to replace a water heater in Sonterra?
Williamson County has no home plumbing permit for unincorporated lots. If your lot is inside Jarrell's city limits, your plumber must be registered with the city and follow its codes. Either way, Texas requires a licensed plumber unless you're the owner working on your own homestead.

Is natural gas available for a gas water heater?
Maybe. Texas Gas Service added Jarrell and the area around it to its rates in July 2025, but we didn't confirm service on individual Sonterra streets. Check with the company before choosing gas.
