Which formation do wells in Mathis draw from?

We cannot say yet for Mathis. 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 Mathis are getting deeper. For reference, the median was 160 feet in 2001 to 2005 (36 wells) and 200 feet in 2021 to 2025 (18 wells).

What a well costs in Mathis

At the median depth for Mathis (180 feet), a complete home well would cost roughly $7,000 to $17,500: $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 (150 to 204 feet) the range runs from $6,500 to $18,500. 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 Mathis, Texas?

Home water wells in and around Mathis, Texas are typically 150 to 204 feet deep (median 180 ft, 39 wells drilled in the last 10 years). One in ten goes past 262 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 Mathis?

At the median depth (180 feet), a complete well would cost roughly $7,000 to $17,500, 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 Mathis?

When the wells were finished, the water stood a median 49 feet below the surface (38 wells), well above the bottom: the typical well holds about 131 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 Mathis?

Mathis is inside the San Patricio 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.
