Which formation do wells in Point Venture draw from?

Most draw from the Lower Trinity (78%), according to the state's Hill Country Trinity model (TWDB). Read that as the most likely layer, not a certain one: where our method names the Lower Trinity, the state's own aquifer code agrees in about 53% of wells.

15% of the wells bottom out near or below the base of the Trinity in the model, often within tens of feet of it; older rock may lie there.

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.

What a well costs in Point Venture

At the median depth for Point Venture (390 feet), a complete home well would cost roughly $12,500 to $30,000: $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 (340 to 449 feet) the range runs from $11,000 to $33,500. 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 Point Venture, Texas?

Home water wells in and around Point Venture, Texas are typically 340 to 449 feet deep (median 390 ft, 110 wells drilled in the last 10 years). One in ten goes past 495 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 Point Venture draw from?

Most draw from the Lower Trinity (78%), according to the state's Hill Country Trinity model (TWDB). Read that as the most likely layer, not a certain one: where our method names the Lower Trinity, the state's own aquifer code agrees in about 53% of wells. This is an estimate from the state's regional model, not a survey of the lot.

How much does a water well cost in Point Venture?

At the median depth (390 feet), a complete well would cost roughly $12,500 to $30,000, 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 Point Venture?

When the wells were finished, the water stood a median 205 feet below the surface (55 wells). The level moves with drought and from one well to the next.

Do I need a permit to drill a well in Point Venture?

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

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 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.
