Which formation do wells in Benavides draw from?
We cannot say yet for Benavides. This atlas assigns layers with the TWDB layered models processed so far (the Northern Trinity and Woodbine model, the Hill Country Trinity model, the northern Gulf Coast Aquifer model and the High Plains Aquifer System model), and none covers this area with enough wells. The depth, water level and yield on this page do come from the real wells here.
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 and around Benavides are getting deeper. For reference, the median was 260 feet in 2001 to 2005 (11 wells) and 340 feet in 2006 to 2010 (11 wells).
| Period | Median depth (ft) | Wells |
|---|---|---|
| 2001–2005 | 260 | 11 |
| 2006–2010 | 340 | 11 |
| 2011–2015 | under 10 wells | 4 |

What a well costs in Benavides
At the median depth for Benavides (320 feet), a complete home well would cost roughly $10,500 to $25,500: $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 (280 to 356 feet) the range runs from $9,500 to $28,000. 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.

Do I need a permit to drill a well in Benavides?
Benavides is inside the Duval County Groundwater Conservation District. Groundwater conservation districts in Texas can require registering or permitting a new well, keeping set distances from property lines and other wells, and paying fees. Rules differ from district to district: ask the district before drilling.
How these numbers are made
We count new and replacement domestic (home) wells whose coordinates fall inside the place boundary or within 2 miles of it. 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.
