Water Well Drilling Contractors in Texas

Geology & Depth

Texas spans multiple major geologic provinces: the Gulf Coastal Plain with thick sand and clay formations, the Edwards Plateau with massive Cretaceous limestone, the Ogallala-capped High Plains in the Panhandle, and the Trans-Pecos region with complex igneous and sedimentary terrain. Each region presents distinctly different drilling challenges.

Most residential wells in Texas are drilled to 225 feet, with a typical range of 50–800 feet. Water table depth: 50-300 feet across the Ogallala (declining significantly); 200-600 feet in the Edwards; 100-1,000+ feet along the Gulf Coast.

Permits & Licensing

Texas requires all water well drillers to be licensed by the Texas Department of Licensing and Regulation (TDLR). Homeowners may drill their own wells on their own property for domestic use, but the well must meet construction standards.

Permit authority: Groundwater Conservation Districts (over 100 across the state) regulate groundwater; the Texas Commission on Environmental Quality (TCEQ) oversees public water supply wells; no statewide permit for domestic wells outside of GCD jurisdiction. Expect $0-$500 (varies by GCD; some areas have no permitting) in permit fees.

Primary Aquifer

Ogallala (High Plains) Aquifer / Edwards (Balcones Fault Zone) Aquifer / Gulf Coast Aquifer / Carrizo-Wilcox Aquifer / Trinity Aquifer. About 14% of Texas households use private wells — over 1 million wells statewide — with the heaviest use in the Hill Country, Panhandle, and rural Gulf Coast.

Best drilling months: Year-round in most of Texas; extreme summer heat in west Texas can slow operations but doesn't prevent drilling.

Common Water Quality Concerns

Texas well water commonly contains: arsenic, fluoride, nitrate, total dissolved solids, radium, hydrogen sulfide, brackish water at depth. A comprehensive water test after drilling (typically $150–$500) will identify which treatments, if any, your well needs.
