A new well in Lampasas County, TX typically costs about $9,500 to $21,100 in 2026 for a complete system, because the median new household well filed with the state since 2016 is 340 feet deep. A shallower well near 250 feet runs about $7,000 to $15,500.
Lampasas County, around Lampasas, Kempner, Lometa, and Adamsville, sits on the northern edge of the Hill Country, between the Trinity limestone plateau and the Llano Uplift, where many rural homes outside a water supply corporation’s lines rely on a private well. Below are the real local depths from state well records, the water-quality issues to plan for, the permit rules, and a free way to reach a licensed local driller.
How deep are wells in Lampasas County?
Most new household wells in Lampasas County are 250 to 410 feet deep, with a median of 340 feet. That comes from 431 new domestic wells drillers reported to the state from 2016 through October 2026 in the TWDB Submitted Driller’s Report database.
| Measure (new domestic wells, 2016 to 2026) | Lampasas County |
|---|---|
| Wells in the sample | 431 |
| Typical depth range (middle half) | 250 to 410 ft |
| Median depth | 340 ft |
| Shallowest 10% / deepest 10% | under 204 ft / over 500 ft |
| Median static water level | 155 ft below ground |
| Median pump setting | 370 ft |
| Median tested yield | 12 gallons per minute |
Static water sits about 155 feet down in a typical Lampasas County well, so the pump is usually set around 370 feet to ride out dry summers.
Which aquifer will my Lampasas County well tap?
Your well will most likely draw from the Trinity Aquifer, which the Saratoga UWCD calls the county’s primary groundwater source, or the Marble Falls, Ellenburger-San Saba, or Hickory aquifers. The TWDB Lampasas County water planning summary lists the Marble Falls and Trinity for rural supply.
The older Llano Uplift aquifers matter most around the city of Lampasas, which pumps the Ellenburger-San Saba for its own supply.
How much does it cost to drill a well in Lampasas County?
Plan on about $9,500 to $21,100 for a complete well at the 340-foot median depth. Angi’s 2026 guide puts Texas well drilling at $28 to $62 per foot (Angi), and HomeGuide puts a complete installation, including casing, pump, wiring, and permits, at $30 to $80 or more per foot (HomeGuide). These are estimates from national cost guides applied to local depths, not local quotes.
| Well depth | Estimated 2026 cost at $28 to $62/ft |
|---|---|
| Shallow (250 ft) | $7,000 to $15,500 |
| Median (340 ft) | $9,500 to $21,100 |
| Deep (410 ft) | $11,500 to $25,400 |
Budget separately for water treatment. HomeGuide lists well-water filtration systems at $800 to $4,000 and water softeners at $1,200 to $3,800. Add the Saratoga UWCD’s $500 registration and intent-to-drill fee. For how the line items break down, see what it costs to drill a well in Texas. If your pump ever needs replacing, here is Texas well pump replacement cost.
Worked example: a 340-foot well at $40 per foot is $13,600. Drilling only to 250 feet at the same rate would save about $3,600 up front, but only if the shallower zone gives enough good water. Ask the driller what nearby wells at that depth produced before you choose.
What water quality problems are common in Lampasas County wells?
Water quality varies more here than in most Hill Country counties. A 2024 City of Lampasas groundwater study found Marble Falls wells near town at 281 to 1,103 mg/L dissolved solids, and Ellenburger-San Saba water that meets drinking standards near Lampasas but worsens quickly to the northeast and with depth, with nearby wells as high as 6,478 mg/L. Most Hickory wells were under 500 mg/L, but combined radium is a concern there (City of Lampasas study).
Lampasas has always had mineral water. Sulphur Creek is fed by springs from fissures in the Marble Falls Limestone, and TWDB measured 1,180 ppm dissolved solids, mostly sodium chloride, where it meets the Lampasas River (TWDB Bulletin 6506). Trinity water is very hard, with sulfate and chloride rising with depth (TWDB).
For reference, the EPA’s secondary (non-health) guidelines are 0.3 mg/L for iron, 250 mg/L for sulfate and chloride, 500 mg/L for dissolved solids, and a pH of 6.5 to 8.5 (EPA). The Texas Well Owner Network guide recommends testing a new well and retesting yearly. If you plan a tankless water heater, read tankless water heaters on well water.
Do I need a permit to drill a well in Lampasas County?
Lampasas County is covered by the Saratoga Underground Water Conservation District. A household well is exempt from permits only on a tract larger than 10 acres and if it cannot pump more than 25,000 gallons a day. A new household well on 10 acres or less needs a district permit, though the permit fees are $0. Every new well must be registered before drilling, and the district issues a notice to proceed within 10 business days of a complete application (SUWCD rules). The registration and intent-to-drill fee is $500 under the schedule effective August 28, 2026 (SUWCD fees). Small wells must sit 150 feet from registered wells and 50 feet from property lines.
Statewide, anyone who drills a water well or installs a well pump must hold a license from the Texas Department of Licensing and Regulation (TDLR), the well must meet TDLR’s minimum distances from septic systems and other contamination sources, and the driller files a State Well Report for every new well. Those reports are the records behind the depth table above. Septic (OSSF) permits are separate; see aerobic vs conventional septic in Texas.
What should I ask a driller before I hire?
- Are you licensed by TDLR as a water well driller and pump installer? (Check the number at the TDLR license search.)
- What depth have your last few wells near my property reached?
- How do you price it: per foot, or a package with casing, pump, tank, and wiring included?
- How salty have your last few wells near me tested, and how deep can you go before the water gets worse?
- Will you handle the Saratoga UWCD registration and any permit for my tract size?
- What happens if the first hole does not produce enough water?
If the well tests low, a storage tank can smooth it out; see storage tanks for low-yield wells. For outages, see sizing a generator for a well pump.

Common questions
Most complete wells in Lampasas County should land around $9,500 to $21,100 in 2026, based on the 340-foot median depth of new domestic wells in state records and Angi’s $28 to $62 per foot Texas range. Treatment and district fees are extra.
The median new household well reported to the state from 2016 to 2026 in Lampasas County is 340 feet deep, and the middle half range from 250 to 410 feet. Median static water level is about 155 feet, per the TWDB Submitted Driller’s Report database.
Every new well in Lampasas County must be registered with the Saratoga UWCD before drilling, and the fee is $500 as of August 2026. A household well is permit-exempt only on more than 10 acres; on 10 acres or less you also need a district permit, which costs $0.
Some aquifers here are naturally mineralized. A 2024 city study found Ellenburger-San Saba wells near Lampasas as high as 6,478 mg/L dissolved solids, and Sulphur Creek’s springs carry mostly sodium chloride. Ask your driller how nearby wells tested before choosing a depth.
Sources: depth, water level, yield, and pump data are Offsprig’s analysis of the TWDB Submitted Driller’s Report download (pulled October 2026; new wells with proposed use “Domestic,” completed 2016 or later). Water-quality figures come from the TWDB and district reports linked above; older studies reflect conditions when sampled. Costs are estimates from Angi and HomeGuide 2026 per-foot ranges, not quotes. Always confirm current rules with TDLR and your groundwater district.
