Water wells in the Jeff Davis County Underground Water Conservation District

Q: What does a groundwater conservation district do?

In Texas, districts are the local authority over groundwater: they can require registration or permits for new wells, set spacing from other wells and property lines, and limit pumping. Each district writes its own rules, so ask the Jeff Davis County Underground Water Conservation District before drilling inside it.

Home water wells inside the Jeff Davis County Underground Water Conservation District (Jeff Davis County, Texas) are typically 296 to 527 feet deep (median 380 ft, 88 wells drilled in the last 10 years). Drillers reported 5 new home wells in 2025, less than half the peak of 22 in 2007. Estimated cost of a complete well at the median depth: $12,000 to $29,500.

Updated every day from Texas Water Development Board driller reports. Last update: November 11, 2026, using the state file of November 10, 2026.

Common questions

How deep are wells in the Jeff Davis County UWCD?

What does a groundwater conservation district do?

In Texas, districts are the local authority over groundwater: they can require registration or permits for new wells, set spacing from other wells and property lines, and limit pumping. Each district writes its own rules, so ask the Jeff Davis County Underground Water Conservation District before drilling inside it.

What a well costs here

At the median depth for the district (380 feet), a complete home well would cost roughly $12,000 to $29,500: $25 to $60 per foot for drilling, casing and seal, plus $2,500 to $6,500 for the pump, pressure tank, controls and hookup at the well. Across the whole middle half of depths (296 to 527 feet) the range runs from $10,000 to $38,000. This is TerraFunded's estimate from published Texas prices, not a quote, and it leaves out trenching and the line to the house. Get prices from at least two licensed drillers.

How these numbers are made

We count new and replacement domestic (home) wells whose coordinates fall inside the district boundary. We use the last 10 years when there are at least 30 wells; otherwise all since 2001. The median is the middle well and the middle half runs from the 25th to the 75th percentile.

These are depths of real wells drilled nearby, not a promise about any property. Groundwater can change over short distances and with drought. A licensed water well driller can tell you what to expect on a specific tract.
