There's a moment that catches a lot of first-time rural Texas landowners off guard: the realization that "we'll just drill a well" is not, in fact, a simple sentence. It involves permits, geology, groundwater politics, a fairly large check, and a timeline that doesn't bend to project schedules. Done right, a water well is one of the best investments on a rural property. Done wrong, it's an expensive lesson.
Here's what you actually need to know before the rig pulls up to your gate.
Texas has 98 groundwater conservation districts covering most of the state, and nearly all of them require a permit before drilling begins. Your driller should pull the permit on your behalf — this is standard practice — but you need to know it's happening and budget for the fee, typically $100 to $600 depending on the district.
Skipping the permit isn't just illegal. An unpermitted well won't appear in the state's groundwater database, which creates complications when you sell the property. Title companies and buyers increasingly ask about well documentation, and "we drilled it without a permit" is not a reassuring answer.
To find your groundwater conservation district, search the Texas Alliance of Groundwater Districts directory at texasgroundwater.org. If your property is in one of the counties without a district, the permit requirement still exists through TDLR at the state level.
Texas sits over several major aquifers — the Edwards, Trinity, Carrizo-Wilcox, Ogallala, Gulf Coast, and others — and your county determines which one you're likely targeting. This matters because aquifer depth, yield, and water quality vary dramatically between them. The Texas Water Development Board maintains a Groundwater Database (GWDB) at twdb.texas.gov where you can search historical well records near your property by county and approximate location. Pull a few records within a mile of your land before your first driller conversation. You'll walk in knowing what depth range to expect, what yields neighbors have gotten, and what the water quality has looked like — none of which the driller will volunteer unless you ask.
Tip: The TWDB database shows depth to water, total depth drilled, and sometimes yield for thousands of wells across Texas. It's free, public, and takes ten minutes to search. Use it.
Where on your property the well goes affects everything downstream — literally. Texas requires a minimum setback distance between the wellhead and any potential contamination source: 50 feet from a septic system drain field, 150 feet from a septic tank, 100 feet from animal pens, and so on. These aren't suggestions.
Beyond the legal setbacks, good site selection also considers access for the drilling rig (a large truck pulling heavy equipment needs a clear path and solid ground), proximity to where you'll need water, and elevation relative to any surface drainage that might pool near the wellhead after heavy rain. Your driller can advise on placement, but knowing the setback rules in advance prevents situations where you've already planned the homesite and the only viable well location is 400 feet away.
From your first call to a licensed driller to having water flowing inside your house, expect four to twelve weeks in normal conditions. Here's how that time breaks down:
If you're building a home and need the well operational for construction water, start this process before you break ground. Waiting until the house is framed puts you behind.
The well itself is the line item people plan for. The items below are the ones that surprise people:
The gap between a $12,000 quote and an $18,000 quote is often the pump, pressure tank, and electrical work. Ask for an itemized quote from every driller and compare apples to apples.
A driller's experience in your specific county matters. The formations in Llano County are nothing like those in Gonzales County. Ask for references from jobs within 20 miles of your property.
You can't tell water quality by looking at it. Arsenic, nitrates, and iron don't announce themselves. Test before you drink.
Texas Well Finder lists TDLR-verified water well drillers across all 195 Texas counties — with license numbers you can verify directly with the state.
