How deep are water wells in West Odessa, Texas?

Home water wells in and around West Odessa, Texas are typically 115 to 160 feet deep (median 130 ft, 1,507 wells drilled in the last 10 years). Most end at or just below the base of the Ogallala, in the top of the Dockum (75%), and 25% draw from the Edwards-Trinity (Plateau) Aquifer, according to the state's High Plains Aquifer System model (TWDB). New wells run about 11% deeper than 20 years ago (median 117 ft in 2003 to 2007, 130 ft in 2021 to 2025). Estimated cost of a complete well at the median depth: $6,000 to $14,500.

Which formation do wells in West Odessa draw from?

Most end at or just below the base of the Ogallala, in the top of the Dockum (75%), and 25% draw from the Edwards-Trinity (Plateau) Aquifer, according to the state's High Plains Aquifer System model (TWDB). Read that as the base of the Ogallala or the top of the Dockum, not a certainty: where our method names the Dockum, the state's own record agrees only about 33% of the time (61% for wells with a screened interval), and most of the others are recorded as Ogallala wells.

Going by the bottom of the hole instead of where the water enters, 93% end at or just below the base of the Ogallala, in the top of the Dockum.

For 78% of these wells the report says where the water enters and we use the middle of that interval; for the rest we use the bottom of the hole, which tends to read one layer too deep.

Depth over time

New home wells in and around West Odessa are deeper than 20 years ago: the median went from 117 feet (2003 to 2007) to 130 feet (2021 to 2025), 11% more. Deeper wells do not always mean the water dropped: a driller may be going for another layer, better water or more reserve.

What a well costs in West Odessa

At the median depth for West Odessa (130 feet), a complete home well would cost roughly $6,000 to $14,500: $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 (115 to 160 feet) the range runs from $5,500 to $16,000. 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.

Common questions

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

Home water wells in and around West Odessa, Texas are typically 115 to 160 feet deep (median 130 ft, 1,507 wells drilled in the last 10 years). One in ten goes past 185 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 West Odessa draw from?

Most end at or just below the base of the Ogallala, in the top of the Dockum (75%), and 25% draw from the Edwards-Trinity (Plateau) Aquifer, according to the state's High Plains Aquifer System model (TWDB). Read that as the base of the Ogallala or the top of the Dockum, not a certainty: where our method names the Dockum, the state's own record agrees only about 33% of the time (61% for wells with a screened interval), and most of the others are recorded as Ogallala 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 West Odessa?

At the median depth (130 feet), a complete well would cost roughly $6,000 to $14,500, 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 West Odessa?

When the wells were finished, the water stood a median 110 feet below the surface (168 wells), close to the bottom: the typical well holds only about 20 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 West Odessa?

In the state's boundary file (current as of November 2019) no groundwater conservation district covers West Odessa. 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 78% of these wells the report says where the water enters and we use the middle of that interval; for the rest we use the bottom of the hole, which tends to read one layer too deep.

How well it works: In 22,814 wells in the Texas part of the state's High Plains Aquifer System model (the Panhandle, the South Plains and the Permian Basin) where the State of Texas recorded the aquifer, the formation our method says the well draws from (as grouped on these pages) is the one the state recorded in about 75% of them; when it names the Dockum (4,542 wells), the state's record agrees only about 33% of the time, and most of the others are recorded as Ogallala wells.

  • The layers come from the Texas Water Development Board's High Plains Aquifer System model, with half mile cells, read here on a grid of about 1.2 by 1.4 miles. It is a regional model, not a survey of any lot.
  • The state's model has half mile cells; we read it on a grid of about 1.2 by 1.4 miles, Texas part only. Layers from version 1.01 (2015); the 2025 extension (1.02) did not change them. It is not a survey of any lot, so we give ranges.
  • Figures go by four groups: Ogallala; Pecos Valley; Edwards-Trinity and Rita Blanca (Cretaceous rock under the Ogallala; the Rita Blanca alone matched the state 19%); Dockum (upper and lower together: the state's codes almost never say which). The Edwards-Trinity group joins three aquifers in different places (High Plains around Lubbock, Plateau around Midland and Odessa, Rita Blanca in Dallam and Hartley): county and place pages name the local one where they can.
  • Dockum: when our method names the Dockum, the state's record agrees only 33% of the time over all years (61% for wells with a screened interval, which is 93% of home wells of the last 10 years); most of the rest are recorded as Ogallala wells. The median well we put in the Dockum ends about 18 ft under the base of the Ogallala as the model draws it. So these pages say "at or just below the base of the Ogallala, in the top of the Dockum", never a certain formation. The state's own 2025 report on this model says depth alone overstates the upper Dockum.
  • "Near or below the base" means the well ends near or below the base of the Dockum, or of the Ogallala where there is no Dockum (Permian red beds; Gray, Carson, Donley, Moore and north Potter counties). Half of these wells end within about 51 ft of the base, and the state usually records them as Ogallala or Dockum wells. That is not an error: the model simply ends there.
  • For old wells without a screened interval (bottom of the hole) the method is only a little better than always saying Ogallala (65% against 58%); with an interval it is 89% against 80%. Figures over all years carry that weakness; last 10 years figures rest almost entirely on intervals.
  • 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.
