How deep are water wells in Crandall, Texas?

Only 10 home water wells in and around Crandall, Texas have been reported since 2001, so treat this as a rough guide: the middle half are 41 to 92 feet deep (median 52 ft). All the wells the model covers are completed in younger formations above the Woodbine, according to the state's Northern Trinity and Woodbine model (TWDB). Estimated cost of a complete well at the median depth: $4,000 to $9,500.

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 Crandall draw from?

All the wells the model covers are completed in younger formations above the Woodbine, according to the state's Northern Trinity and Woodbine model (TWDB).

Only 10% of these wells have the water-bearing interval on their report (reports before about 2012 rarely do). For the others we use the bottom of the hole, which tends to read one layer deeper than where the water actually comes from.

What a well costs in Crandall

At the median depth for Crandall (52 feet), a complete home well would cost roughly $4,000 to $9,500: $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 (41 to 92 feet) the range runs from $3,500 to $12,000. 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 Crandall, Texas?

Only 10 home water wells in and around Crandall, Texas have been reported since 2001, so treat this as a rough guide: the middle half are 41 to 92 feet deep (median 52 ft). One in ten goes past 120 feet. The depth a given tract needs depends on where it sits and what layers the driller hits.

What aquifer or formation do wells in Crandall draw from?

All the wells the model covers are completed in younger formations above the Woodbine, according to the state's Northern Trinity and Woodbine model (TWDB). This is an estimate from the state's regional model, not a survey of the lot.

How much does a water well cost in Crandall?

At the median depth (52 feet), a complete well would cost roughly $4,000 to $9,500, by TerraFunded's estimate from published Texas driller prices. The real price comes from a licensed driller's quote.

Do I need a permit to drill a well in Crandall?

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

To tell which layer a well draws from, we take the ground elevation at its location, subtract the depth of the interval where water enters (or the bottom of the hole when the report does not give one) and see which layer of the state's model that point falls in.

Only 10% of these wells have the water-bearing interval on their report (reports before about 2012 rarely do). For the others we use the bottom of the hole, which tends to read one layer deeper than where the water actually comes from.

How well it works: In 7,977 wells in the area of the state's Northern Trinity and Woodbine model (North and Central Texas) where the State of Texas recorded the aquifer, our estimate of the formation the well draws from names the same layer of the state's model in about 74% of them, and that layer or the one next to it in at least 95%; among the 3,130 of those wells that the state places in a Trinity layer (Paluxy to Hosston) it is about 56%.

  • The layers come from the Texas Water Development Board's Northern Trinity and Woodbine model, with quarter mile cells, summarized here to about 1.3 miles. It is a regional model, not a survey of any lot: between one model point and the next, the real depth of each layer can differ.
  • In this model every layer is at least 30 feet thick, even where the real rock is thinner or missing. Thin layers and the edges of the model are approximate.
  • Inside the Trinity this atlas does not name single model layers: it groups the Paluxy and Glen Rose (upper Trinity) and groups the Hensell, Pearsall and Hosston (lower Trinity, Twin Mountains and Travis Peak), because the check against the state's codes shows the method cannot separate them reliably.
  • "Near or below the base of the Trinity" means the well reaches the bottom of the model or passes it, often by tens of feet. Older rock that the model does not include may lie there.
  • We never use the model's water levels. The water level on this page is the one each driller measured when the well was finished.

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.
