The typical Texas home well gives 25 gallons per minute, but only 12% of the figures come from a pump test

Drillers reported a median yield of 25 gallons per minute for Texas home wells, with the middle half between 15 and 50 (89,555 wells, last 10 years). Only 12% of those figures come from a pump test; the rest are quicker tests or the driller's estimate. By county, among the 208 with at least 30 wells with a yield, the median runs from 7 gallons per minute in Archer County to 75 gallons per minute in Calhoun County. In 6 counties the median is under 10.

What this shows and what it doesn't

  • Most yields are quick tests or estimates made the day the well was finished, not a pump test over hours. Treat them as a rough guide to how the area's wells compare.
  • A home runs on a few gallons per minute with storage. A low county median does not mean the wells fail; a high one often reflects wells built for more than a house.
  • Yield can fall in dry years and with the age of the well. The report records it once.

Questions

How many gallons per minute does a water well produce in Texas?

Drillers reported a median yield of 25 gallons per minute for Texas home wells, with the middle half between 15 and 50 (89,555 wells, last 10 years). Only 12% of those figures come from a pump test; the rest are quicker tests or the driller's estimate. By county, among the 208 with at least 30 wells with a yield, the median runs from 7 gallons per minute in Archer County to 75 gallons per minute in Calhoun County. In 6 counties the median is under 10.

Are the yields on Texas well reports reliable?

As a rough guide. Only 12% of the yields on home well reports of the last 10 years come from a pump test; the rest are quicker tests or estimates made the day the well was finished.

Sources you can check

Check it yourself

  1. Download this page's table as a CSV (texas-water-well-yield-by-county.csv): every figure in the text is in it.
  2. Open any county in the table. Its page lists its figures, and each well on its map opens the official report on the state's site.
  3. For the raw data, download the state file from the TWDB link in the sources and keep the wells whose proposed use is Domestic and whose work is a new well or a replacement.
  4. If a figure does not match, write to us with the county and the number: we correct it in the next update and say so.

How we got it

We count new and replacement domestic (home) wells with a valid depth on their report. Monitoring wells, soil borings, injection, geothermal and oilfield wells are left out. A depth under 10 feet or over 5,000 feet is treated as an entry error.

Yield is the report's best test, preferring a pump test over any other test or an estimate. We use the wells of the last 10 years when there are at least 30; otherwise all since 2001.
