Which formation do wells in La Vernia draw from?

We cannot say yet for La Vernia. 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.

What a well costs in La Vernia

At the median depth for La Vernia (340 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 (285 to 402 feet) the range runs from $9,500 to $30,500. 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.

Common questions

How deep do you have to drill a well in La Vernia, Texas?

Home water wells in and around La Vernia, Texas are typically 285 to 402 feet deep (median 340 ft, 101 wells drilled in the last 10 years). One in ten goes past 450 feet. The depth a given tract needs depends on where it sits and what layers the driller hits.

How much does a water well cost in La Vernia?

At the median depth (340 feet), a complete well would cost roughly $11,000 to $27,000, by TerraFunded's estimate from published Texas driller prices. The real price comes from a licensed driller's quote.

How deep is the water in La Vernia?

When the wells were finished, the water stood a median 110 feet below the surface (99 wells), well above the bottom: the typical well holds about 230 feet of water. The level moves with drought and from one well to the next.

Do I need a permit to drill a well in La Vernia?

La Vernia is inside the Evergreen Underground Water 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.
