How deep are water wells in Mexia, Texas?

Q: How much does a water well cost in Mexia?

At the median depth (215 feet), a complete well would cost roughly $8,000 to $19,500, by TerraFunded's estimate from published Texas driller prices. The real price comes from a licensed driller's quote.

Q: Do I need a permit to drill a well in Mexia?

In the state's boundary file (current as of November 2019) no groundwater conservation district covers Mexia. Districts created or enlarged since then are missing from that file, so confirm with the county or TWDB before drilling. Anywhere in Texas the well must be drilled by a licensed driller, who files the report with the state.

Only 11 home water wells in and around Mexia, Texas have been reported since 2001, so treat this as a rough guide: the middle half are 82 to 398 feet deep (median 215 ft). Estimated cost of a complete well at the median depth: $8,000 to $19,500.

This page is based on fewer than 30 wells, so it is kept out of search engines until more reports come in. Treat every figure as a rough guide.

Which formation do wells in Mexia draw from?

We cannot say yet for Mexia. 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 Mexia

At the median depth for Mexia (215 feet), a complete home well would cost roughly $8,000 to $19,500: $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 (82 to 398 feet) the range runs from $4,500 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.

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.
