Water wells in the Presidio County Underground Water Conservation District
Home water wells inside the Presidio County Underground Water Conservation District (Presidio County, Texas) are typically 301 to 482 feet deep (median 343 ft, 60 wells drilled in the last 10 years). Drillers reported 2 new home wells in 2025, less than half the peak of 13 in 2019. Estimated cost of a complete well at the median depth: $11,000 to $27,000.

Depth over time
There are not enough wells in both 2003 to 2007 and 2021 to 2025 (at least 30 in each) to say with confidence whether wells in the district are getting deeper. For reference, the median was 390 feet in 2001 to 2005 (14 wells) and 420 feet in 2021 to 2025 (21 wells).

Common questions
How deep are wells in the Presidio County UWCD?
Home water wells inside the Presidio County Underground Water Conservation District (Presidio County, Texas) are typically 301 to 482 feet deep (median 343 ft, 60 wells drilled in the last 10 years).
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 Presidio County Underground Water Conservation District before drilling inside it.
What a well costs here
At the median depth for the district (343 feet), a complete home well would cost roughly $11,000 to $27,000: $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 (301 to 482 feet) the range runs from $10,000 to $35,500. 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.
