Question

How long is the lifespan of a private water well?

Answer 1

Too many variables to say with certainty.  Depends on how the well was built, with what materials, and the aggressivity of the water in corroding or destroying the well casing and screen (if you even have).  Frequent overpumping can ruin a well also.

In most circumstances, decades is a reasonable time frame to expect.  You are likely to need to replace the pump before you need to replace the well, assuming that nothing from the outside is affecting the water quality.  Having said that, it is not unusual to need to occasionally verify the integrity of the well, that the well has remained sealed against the influx of near surface (and more likely contaminated) groundwater.

I know of many many many private wells that have been in continual use for decades without serious problems, but have also been involved in replacing such wells, some installed as recently as 15 years.  No simple answer to your question.  very much depends on circumstances and quality of the installation.

Answer 2

In Oklahoma here with the aquifer we are above we have pumped steadily for 25 years.    If someone does s***w it up it should stay available.    Calling your local Extension Service office will tell you what the situations generally are in your locality.   Often they are listed as county  Extension Serives but not always.    

Answer 3

A long time! Mine was here way before I was born and we have had no problems at all. They come and check it once a week (to make sure it doesnt need to be pumped out or anything) and thats it.
