Well Drilling Cost in Texas

Well drilling costs in Texas vary significantly by region. The Hill Country, West Texas, and the Panhandle all have different geology that affects both depth required and cost per foot.

Average Total Cost
$5,500 – $12,000
Cost Per Foot
$25 – $65
Average Depth
150 – 400 ft
Casing Required
Yes — TCEQ regulated
Texas Well Drilling Cost Breakdown
The total cost of drilling a water well in Texas typically ranges from $5,500 to $12,000 for a standard residential well. This includes drilling, casing, pump installation, and pressure tank. Depth is the biggest variable — Hill Country wells may only need 150–200 feet while West Texas wells often require 400–600 feet to reach usable water.
Cost Per Foot in Texas
Drilling contractors in Texas typically charge $25–$65 per foot for drilling and casing combined. Harder rock formations (granite, limestone in the Hill Country) cost more per foot due to slower penetration rates. Soft clay and sand formations drill faster and cost less.
Regional Depth Differences
The Edwards Aquifer (Central Texas, San Antonio area) wells typically reach water at 100–300 feet. Trinity Aquifer wells (DFW to Austin corridor) often require 300–500 feet. West Texas Permian Basin wells may need 500–1,000+ feet and often produce lower quality water requiring treatment.
Texas TCEQ Regulations
Texas water wells must meet Texas Commission on Environmental Quality (TCEQ) standards. Drillers must be licensed. Steel or PVC casing is required from surface to at least 20 feet below the static water level. A surface seal of concrete or bentonite grout is required for the top 10–50 feet.
Additional Costs to Budget
Well pump: $800–$2,500 depending on depth and submersible vs jet pump. Pressure tank: $300–$800. Electrical connection: $500–$1,500. Water treatment (if needed): $500–$5,000. Total system cost including all components typically runs $8,000–$18,000 for a complete residential well installation.
Common Questions
The average cost to drill a complete residential water well in Texas is $8,000–$18,000 installed, including pump, pressure tank, and electrical. Drilling alone (without pump) costs $5,500–$12,000. The biggest variable is depth — West Texas wells are significantly more expensive than Central Texas wells.
Well depth in Texas varies dramatically by region. Hill Country wells may reach water at 100–200 feet. DFW area wells often require 300–500 feet. West Texas wells frequently need 500–1,000+ feet. Your driller will know the typical depths in your specific county.
Texas requires a well completion report filed with TCEQ within 30 days of completion, and the driller must be TCEQ licensed. Some Groundwater Conservation Districts require permits before drilling — check with your local GCD first.
Most residential wells take 1–3 days to drill. Deeper wells or hard rock formations may take 3–5 days. Pump installation and completion typically adds 1–2 more days.
Texas has multiple major aquifers. The Edwards Aquifer serves Central Texas and San Antonio. The Trinity Aquifer serves the DFW to Austin corridor. The Ogallala Aquifer underlies the Panhandle and High Plains. The Carrizo-Wilcox serves East Texas.
