How deep are water wells in Hutto, Texas?

Home water wells in and around Hutto, Texas vary a lot in depth: the middle half are 38 to 598 feet deep (median 468 ft, 54 wells reported since 2001), so look at the wells closest to the tract. Most are completed in the Washita and Fredericksburg groups (65%), and 35% 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: $14,000 to $34,500.

Which formation do wells in Hutto draw from?

Most are completed in the Washita and Fredericksburg groups (65%), and 35% are completed in younger formations above the Woodbine, according to the state's Northern Trinity and Woodbine model (TWDB).

Layer (state's model)ShareWellsTypical depth (ft)
Washita and Fredericksburg65%35475–640
Above the Woodbine35%1930–39

Only 41% 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.

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 Hutto are getting deeper. For reference, the median was 500 feet in 2001 to 2005 (10 wells) and 36 feet in 2016 to 2020 (13 wells).

What a well costs in Hutto

At the median depth for Hutto (468 feet), a complete home well would cost roughly $14,000 to $34,500: $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 (38 to 598 feet) the range runs from $3,500 to $42,500. 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 Hutto, Texas?

Home water wells in and around Hutto, Texas vary a lot in depth: the middle half are 38 to 598 feet deep (median 468 ft, 54 wells reported since 2001), so look at the wells closest to the tract. One in ten goes past 674 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 Hutto draw from?

Most are completed in the Washita and Fredericksburg groups (65%), and 35% 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 Hutto?

At the median depth (468 feet), a complete well would cost roughly $14,000 to $34,500, 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 Hutto?

When the wells were finished, the water stood a median 200 feet below the surface (49 wells), well above the bottom: the typical well holds about 268 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 Hutto?

In the state's boundary file (current as of November 2019) no groundwater conservation district covers Hutto. 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 41% 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.
