How deep are water wells in Primera, Texas?

Home water wells in and around Primera, Texas vary a lot in depth: the middle half are 50 to 140 feet deep (median 65 ft, 37 wells drilled in the last 10 years), so look at the wells closest to the tract. Estimated cost of a complete well at the median depth: $4,000 to $10,500.

Updated every day from Texas Water Development Board driller reports. Last update: November 11, 2026, using the state file of November 10, 2026.

Which formation do wells in Primera draw from?

We cannot say yet for Primera. 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 Primera are getting deeper. For reference, the median was 130 feet in 2001 to 2005 (88 wells) and 65 feet in 2021 to 2025 (18 wells).

What a well costs in Primera

At the median depth for Primera (65 feet), a complete home well would cost roughly $4,000 to $10,500: $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 (50 to 140 feet) the range runs from $4,000 to $15,000. 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.

Common questions

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

Home water wells in and around Primera, Texas vary a lot in depth: the middle half are 50 to 140 feet deep (median 65 ft, 37 wells drilled in the last 10 years), so look at the wells closest to the tract. One in ten goes past 191 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 Primera?

At the median depth (65 feet), a complete well would cost roughly $4,000 to $10,500, 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 Primera?

When the wells were finished, the water stood a median 10 feet below the surface (37 wells), well above the bottom: the typical well holds about 55 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 Primera?

In the state's boundary file (current as of November 2019) no groundwater conservation district covers Primera. 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.

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.
