Which formation do wells in Atlanta draw from?

We cannot say yet for Atlanta. 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 Atlanta

At the median depth for Atlanta (340 feet), a complete home well would cost roughly $11,000 to $27,000: $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 (310 to 368 feet) the range runs from $10,500 to $28,500. 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 Atlanta, Texas?

Home water wells in and around Atlanta, Texas are typically 310 to 368 feet deep (median 340 ft, 71 wells drilled in the last 10 years). One in ten goes past 396 feet. The depth a given tract needs depends on where it sits and what layers the driller hits.

How much does a water well cost in Atlanta?

At the median depth (340 feet), a complete well would cost roughly $11,000 to $27,000, 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 Atlanta?

When the wells were finished, the water stood a median 120 feet below the surface (64 wells), well above the bottom: the typical well holds about 220 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 Atlanta?

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

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.
