How deep are water wells in Arp, Texas?

Q: How much does a water well cost in Arp?

At the median depth (476 feet), a complete well would cost roughly $14,500 to $35,000, by TerraFunded's estimate from published Texas driller prices. The real price comes from a licensed driller's quote.

Q: How deep is the water in Arp?

When the wells were finished, the water stood a median 232 feet below the surface (26 wells). The level moves with drought and from one well to the next.

Q: Do I need a permit to drill a well in Arp?

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

Only 26 home water wells in and around Arp, Texas have been reported since 2001, so treat this as a rough guide: the middle half are 360 to 510 feet deep (median 476 ft). Estimated cost of a complete well at the median depth: $14,500 to $35,000.

This page is based on fewer than 30 wells, so it is kept out of search engines until more reports come in. Treat every figure as a rough guide.

Which formation do wells in Arp draw from?

We cannot say yet for Arp. This atlas assigns layers with the TWDB layered models processed so far (the Northern Trinity and Woodbine model, the Hill Country Trinity model, the northern Gulf Coast Aquifer model and the High Plains Aquifer System model), and none covers this area with enough wells. The depth, water level and yield on this page do come from the real wells here.

What a well costs in Arp

At the median depth for Arp (476 feet), a complete home well would cost roughly $14,500 to $35,000: $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 (360 to 510 feet) the range runs from $11,500 to $37,000. 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.

How deep do you have to drill a well in Arp, Texas?

Only 26 home water wells in and around Arp, Texas have been reported since 2001, so treat this as a rough guide: the middle half are 360 to 510 feet deep (median 476 ft). One in ten goes past 575 feet. The depth a given tract needs depends on where it sits and what layers the driller hits.

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.

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.
