What a well costs in Woodcreek

At the median depth for Woodcreek (495 feet), a complete home well would cost roughly $15,000 to $36,000: $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 (350 to 602 feet) the range runs from $11,500 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 Woodcreek, Texas?

Home water wells in and around Woodcreek, Texas are typically 350 to 602 feet deep (median 495 ft, 44 wells drilled in the last 10 years). One in ten goes past 698 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 Woodcreek draw from?

Nearly all draw from the Middle Trinity (98%), according to the state's Hill Country Trinity 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 Woodcreek?

At the median depth (495 feet), a complete well would cost roughly $15,000 to $36,000, 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 Woodcreek?

When the wells were finished, the water stood a median 214 feet below the surface (32 wells), well above the bottom: the typical well holds about 281 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 Woodcreek?

Woodcreek is inside the Hays 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 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 2,665 wells in the Texas Hill Country 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 76% of them, and that layer or the one next to it in at least 98%.

  • The layers come from the Texas Water Development Board's Hill Country Trinity model, with 1 mile cells. 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.
  • "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.
