Which formation do wells in Grandview draw from?

No single layer dominates: 50% end at or just below the base of the Woodbine (Washita and Fredericksburg groups) and 50% draw from the Woodbine Aquifer, according to the state's Northern Trinity and Woodbine model (TWDB).

Going by the bottom of the hole instead of where the water enters, 65% end at or just below the base of the Woodbine (Washita and Fredericksburg groups).

For 98% of these wells the report says where the water enters (the screen or the open hole), and we use the middle of that interval.

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 Grandview are getting deeper. For reference, the median was 240 feet in 2001 to 2005 (18 wells) and 180 feet in 2026 (20 wells).

What a well costs in Grandview

At the median depth for Grandview (200 feet), a complete home well would cost roughly $7,500 to $18,500: $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 (179 to 220 feet) the range runs from $7,000 to $19,500. 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 Grandview, Texas?

Home water wells in and around Grandview, Texas are typically 179 to 220 feet deep (median 200 ft, 123 wells drilled in the last 10 years). One in ten goes past 240 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 Grandview draw from?

No single layer dominates: 50% end at or just below the base of the Woodbine (Washita and Fredericksburg groups) and 50% draw from the Woodbine Aquifer, 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 Grandview?

At the median depth (200 feet), a complete well would cost roughly $7,500 to $18,500, 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 Grandview?

When the wells were finished, the water stood a median 110 feet below the surface (76 wells). The level moves with drought and from one well to the next.

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

Grandview is inside the Prairielands 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 98% 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.
  • "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.
