New Water Well Drilling

A new well is a long-term investment: a properly built well can serve a home for decades. Here's how the process usually works around Tyler, Smith County and East Texas, and what to ask your driller.

Local groundwater

Tyler and Smith County sit over the Carrizo-Wilcox Aquifer, one of Texas's major aquifers. The Texas Water Development Board describes it as sand interbedded with gravel, silt, clay and lignite, with freshwater sands averaging about 670 feet of saturated thickness, and notes isolated areas of slightly to moderately saline water. TWDB has studied Carrizo-Wilcox drawdown in Rusk, Smith and Gregg counties. In practice, well depth and water quality depend on exactly where you are and which sand the driller screens.

Step by step

Siting. The well needs room for the drill rig and required separation distances from septic tanks and fields, animal areas, fuel tanks and property lines. It should sit on ground that drains away from the wellhead, not in a low spot where surface water collects.
Permits and paperwork. Your TDLR-licensed driller files the state well report. Check whether a groundwater conservation district covers your county and whether it requires registration or a permit, and ask about any city requirements if you're inside city limits.
Utility locates. The driller or electrician calls 811 (Texas811) before trenching for the water line and power.
Drilling. Rotary or air-rotary rigs drill through soil and rock to a water-bearing zone. The driller logs the formations and water levels.
Casing and grout. Steel or PVC casing is set through the soil and weathered rock, and the annular space is sealed with cement or bentonite grout so surface water can't run down the outside of the casing. This seal is one of the most important protections for your water quality.
Development and yield test. The well is pumped or surged to clear fines, and its yield (gallons per minute) is measured.
Pump system. A submersible pump, drop pipe, wire, pitless adapter (connection below frost line), pressure tank and switch are installed.
Disinfection and testing. The well is shock-chlorinated, flushed and sampled. The EPA recommends testing private wells for bacteria and other contaminants; new wells should be tested before you drink the water.
Well report. The contractor files the completion report with the state, and you should keep a copy.

How deep will my well be?

Nobody can promise a depth before drilling. The best predictor is nearby wells. Search the TWDB Submitted Drillers Reports database for wells near your address to see recorded depths. WellDrillingCosts puts the average Texas residential well at about 225 feet. Yield matters as much as depth: a household needs enough flow to run fixtures and recover, and storage (a bigger pressure tank or a storage tank) can help low-yield wells.

Questions to ask a driller

Are you licensed or registered with the state? (Ask for the number.)
Is the price per foot, or a package? What happens if you go deeper than estimated?
What casing depth and grouting method do you use?
Does the price include the pump, pressure tank, pitless adapter, trenching to the house and electrical hookup?
Who handles disinfection and the first water test?
What warranty do you give on the pump and workmanship?

Replacing an old well

Old dug wells, shallow wells and wells with damaged casing are more exposed to surface contamination. If you're replacing one, the old well should be properly plugged (filled and sealed) under state rules so it doesn't become a pathway for contamination into the aquifer.

Well yield and household needs

Yield is measured in gallons per minute. A household's peak demand happens when several fixtures run at once, such as a shower, dishwasher and washing machine. Low-yield wells can still serve a home if there's enough storage: a deep well holds water in the borehole itself, and a storage tank with a booster pump can make a marginal well workable. Irrigation and livestock add demand, so tell your driller about every use you plan. In bedrock areas, a driller may suggest hydrofracturing a low-yield well, which uses high-pressure water to open fractures and can improve flow.

Geothermal and irrigation wells

Not every well is for drinking water. Irrigation wells for lawns, gardens and orchards and closed-loop geothermal boreholes for heat pumps are often drilled by the same contractors, with different construction rules. Ask whether your planned use needs a different permit or registration.

What you'll get at the end

A finished well should include a copy of the well completion report (depth, casing, static water level, yield), the pump and tank specs and warranties, the first water test results, and a note of where the line and wire run to the house. Keep them together. They're valuable when you sell the property or need service.

Before you call a contractor: a checklist

Address or parcel and whether public water is available.
What the water is for. House, irrigation, livestock or all of them.
Existing well details if you have one: depth, age, pump age and any records.
Symptoms for repairs: no water, low pressure, short cycling, air, sediment, taste or smell.
Septic location, so the new well can meet separation distances.
Access for a drill rig (they're large trucks) and the distance to the house.
Neighbors' well depths if you know them.
Timeline, including any closing or construction deadline.

The more a contractor knows up front, the more accurate the first estimate.

Common questions

How long does it take to drill a well?

Drilling itself often takes one to a few days. Scheduling, permits, the pump install and testing add time.

Can a well run dry?

Yes, especially shallow wells during drought. Deeper wells into reliable formations are less vulnerable. A contractor can deepen or replace a failing well.

Can I choose where the well goes?

Within limits. Separation distances from septic systems, property lines and other hazards, plus rig access, narrow the choices. Your contractor will recommend a spot.

What is a pitless adapter?

A fitting on the side of the casing below frost depth that lets the water line exit underground, so nothing freezes and the top of the well stays sealed.

Do I need to disinfect a new well?

Yes. New wells should be disinfected and tested before you drink the water.
