Which water and septic services are available in Matagorda County?

Matagorda County runs from farm country around Bay City, Markham, and Van Vleck all the way down to the coast at Sargent, Matagorda, and Palacios, and the water story changes as you head south. Inland wells hit dependable freshwater. Closer to the bays, well siting and depth become the difference between good water and a brackish problem.

We drill wells, service pumps, install and maintain septic systems, and design water treatment across the whole county, including the coastal stretch where getting it right the first time matters most.

Beach houses and bay properties bring their own septic reality too: sandy soil and a high water table usually mean an aerobic system, and we install and service those on maintenance contracts.

What should property owners know about water in Matagorda County?

Inland Matagorda County draws from the Gulf Coast Aquifer, and wells here run deeper than in the neighboring counties. State driller reports put most domestic wells between 170 and 550 feet, with the middle around 400. As you move toward the coast, freshwater zones get thinner and brackish risk increases, which is why coastal well work starts with careful siting and depth planning rather than just setting up where it's convenient.

Every well in the county gets registered with the Coastal Plains Groundwater Conservation District before drilling, and typical household and livestock wells are exempt from production permitting. Larger non-exempt wells also carry a 200-foot minimum screening depth under district rules. We handle all of it as part of the job.

For coastal properties where the well water carries salts or minerals treatment can't economically fix at whole-home scale, we'll tell you that straight and design around it. Point-of-use treatment for drinking water, or a different siting plan entirely. Nobody should pay for a well that produces water they can't use.

What do Matagorda County property owners ask about wells and septic?

If yours isn't here, call or text 979-320-4940.

Can you drill a freshwater well near the coast in Matagorda County?
Often yes, but coastal wells demand more careful siting and depth planning than inland wells. Freshwater zones thin out as you approach the bays and brackish intrusion becomes a real risk. We evaluate your specific site before quoting. If a location can't reliably produce usable water, we tell you that before you spend money, not after.
What kind of septic system does a Sargent or Matagorda beach house need?
Coastal properties with sandy soil and a high water table usually require an aerobic septic system rather than a conventional drain field. Aerobic systems in Texas require ongoing licensed maintenance, and we cover that with service contracts. Inspections, chlorinator checks, and filter cleaning on schedule.
How deep are water wells around Bay City?
State driller reports put most domestic wells in Matagorda County between 170 and 550 feet, with the middle around 400. Deeper than neighboring Wharton County. Coastal tracts are evaluated case by case because usable freshwater depth changes as you approach the bays. We give you a site-specific expectation before drilling starts.
My coastal well water tastes salty or leaves white residue. Can it be treated?
It depends on the concentration, which is why we start with a certified lab test. Moderate mineral content is treatable with the right system. Genuinely brackish water is expensive to treat at whole-home scale, and we'll tell you honestly when point-of-use treatment for drinking water or a re-sited well is the smarter money.
Do you serve Palacios and the western side of the county?
Yes. We cover all of Matagorda County. Bay City, Van Vleck, Markham, Blessing, Midfield, Palacios, and the coastal communities at Sargent and Matagorda. Our El Campo shop puts most of the county within about 45 minutes.
