Call now, 24/7(737) 717-0737The City of Lockhart is your utility
A department that handles water and wastewater
Unlike many Hill Country communities, Lockhart has a city department in charge of both. The City of Lockhart Water/Wastewater Department operates the water system and a wastewater treatment plant. Its website also links a page on water restrictions and a notice about water service lines, which are worth a look if you are seeing problems at the meter or planning a yard project. The first stop for any account question is the city bill.
The city page does not spell out who owns each piece of the sewer collection pipe, so ask the city where its part ends and your lateral begins before a buried repair. Our page on sewer line repair explains how that division usually matters when a line cracks.
| Topic | What to do |
|---|---|
| Account or meter question | Contact the city using your bill |
| Watering limits | Read the city’s water restrictions page |
| Service line notice | See the notice on the city website |
| Leak between meter and house | Call us, then tell the city if the meter is involved |
Your side of the meter
Most household leaks live on your side: the supply pipe from the meter, the fixtures and the water heater. A simple home test is to turn off every tap and watch the meter. If the small triangle or dial keeps moving, water is leaking somewhere. The water leak guide walks through the steps, and water line repair covers the buried pipe.
- Close every tap and applianceDishwasher and ice maker too.
- Read the meterWrite down the digits.
- Wait fifteen minutesDo not use water.
- Read it againA change means a leak.
A blend of two aquifers and river water
Three sources, one tap
The city’s 2025 water quality report says Lockhart’s supply comes from the Wilcox Aquifer, from city wells treated at the Lockhart plant operated by the Guadalupe-Blanco River Authority, from the Carrizo Aquifer through GBRA wells treated at the Alliance Regional Water Authority plant, and from San Marcos River surface water treated at the GBRA Luling plant. Groundwater supplies are blended with surface water, so the mix is not fixed.
Because the blend moves, minerals can shift with it. A utility-reported test in June 2022 gave about 6 grains per gallon for the city system, which is moderately hard. That test is older and the range in third-party listings runs higher, so call the city for a figure that matches your street now. Our hard water guide shows what the signs look like.
| Source | Treated at |
|---|---|
| Wilcox Aquifer wells | Lockhart plant, run by GBRA |
| Carrizo Aquifer wells | Alliance Regional Water Authority plant |
| San Marcos River | GBRA Luling plant |
| Result | Groundwater blended with surface water |
Why scale still matters
Even moderate hardness adds up over time. Heaters pick up a layer at the bottom of the tank, shower heads clog at the holes, and faucet aerators lose flow. A tank flush now and then slows the problem, while a water softener stops most of it at the source. If you only want better taste, water filtration is a smaller job.
Look for the crust
Faucet tips, shower heads and kettles show it first.
Ask the city
Request a current hardness figure for your address.
Flush or replace the heater
Sediment shortens life and cuts efficiency.
Treat the water
Pick a softener, a filter or both.
Water heater trouble in a mixed-water town
What a failing heater tells you
Sounds and drips are the early warnings. A popping noise means sediment trapped under the water. Rusty water from only the hot side points to the tank. A puddle at the base means the shell has given up. For a full list of causes and fixes, read water heater repair in Lockhart, which covers the details for local homes, and the core water heater repair page for the general view.
| Sign | Usual cause | Next step |
|---|---|---|
| Popping or rumbling | Sediment on the tank floor | Flush, then reassess |
| Rusty hot water only | Tank corrosion | Plan a replacement |
| Pooling water at the base | Leaking tank or valve | Shut off supply, call |
| No hot water at all | Element, thermostat or gas control | Check power or pilot, then call |
Repair or replace
A heater with a minor fault is usually worth repairing. One with a leaking shell is not. Age matters too, and the repair versus replacement guide has a way to weigh it. If you want to cut standby loss, a tankless unit is another option, with its own installation needs.
- Under ten years, small faultRepair is common.
- Leaking shellReplace.
- Repeated repairsReplacement pencils out.
- Hard-water scaleFlush plus treatment.
Owners and renters: who calls whom
A town with a third of homes rented
The Census Bureau estimates 18,159 people live in Lockhart, with 67.0 percent of homes owner-occupied across 5,437 households. That means roughly a third of households rent. For a renter, a leak that damages property is a landlord matter, and the landlord or property manager can call us to arrange a visit. For an owner, the decision is yours. Either way, shut off the water at the nearest valve when something bursts, then call.
| If you | First step | Then |
|---|---|---|
| Own the home | Close the main, call | Decide on repair |
| Rent the home | Close the nearest valve, notify the landlord | Landlord or manager arranges the call |
| Manage rentals | Collect the unit address and symptom | Call with those notes |
| Are away | Ask someone to check the house | Call once the problem is confirmed |
Leaks the city report warns about
Lockhart’s 2025 water quality report urges residents to fix leaks and dripping faucets and to use low-flow fixtures. It is the same advice a plumber would give: a faucet losing a drip a second wastes a lot over a month. A faucet repair or a toilet repair visit pays back quickly when the bill drops.
Find the drip
Check taps, supply lines and shut-off valves.
Test the toilet
A few drops of food color in the tank show a flapper leak.
Fix small parts
Washers, flappers and cartridges are small parts with a big effect on the bill.
Recheck the meter
A calmer dial means the fix worked.
