How deep are water wells in Peaster, Texas?

Home water wells in and around Peaster, Texas are typically 200 to 240 feet deep (median 220 ft, 799 wells drilled in the last 10 years). Nearly all (94%) draw from the Trinity, which the state maps here as one undivided unit, the Antlers Formation; by depth, roughly 64% fall in its upper part and 30% in its lower part, an approximate split. Estimated cost of a complete well at the median depth: $8,000 to $19,500.

Which formation do wells in Peaster draw from?

Nearly all (94%) draw from the Trinity, which the state maps here as one undivided unit, the Antlers Formation; by depth, roughly 64% fall in its upper part and 30% in its lower part, an approximate split.

What a well costs in Peaster

At the median depth for Peaster (220 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 (200 to 240 feet) the range runs from $7,500 to $21,000. 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 Peaster, Texas?

Home water wells in and around Peaster, Texas are typically 200 to 240 feet deep (median 220 ft, 799 wells drilled in the last 10 years). One in ten goes past 260 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 Peaster draw from?

Nearly all (94%) draw from the Trinity, which the state maps here as one undivided unit, the Antlers Formation; by depth, roughly 64% fall in its upper part and 30% in its lower part, an approximate split. This is an estimate from the state's regional model, not a survey of the lot.

How much does a water well cost in Peaster?

At the median depth (220 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.

How deep is the water in Peaster?

When the wells were finished, the water stood a median 80 feet below the surface (313 wells), well above the bottom: the typical well holds about 140 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 Peaster?

Peaster is inside the Upper Trinity 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.

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.

For 99% of these wells the report says where the water enters (the screen or the open hole), and we use the middle of that interval.

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.
  • In this area, north and west of Fort Worth, the state maps the Trinity as one undivided unit, the Antlers Formation. The model cuts it into layers by depth; the split between upper and lower Trinity shown here is approximate, and the depth ranges are the solid part.
  • "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.
