What is the average life expectancy of a well?

Wednesday, January 15, 2020

You can expect a well to last about 20 to 50 years, with an average of 35 years. The well pump should have an 10 to 16 year life, with an average of 12 years. So many factors affect the life of a well that it’s difficult pin it down to within a shorter range, and it’s possible for a well to fail even sooner than 20 years. Here’s a few examples:

• A years-long drought can cause the water table to recede, requiring a deeper well.

• Dug wells usually have a shorter life than drilled wells.

• Water quality can deteriorate or become contaminated over time.

• Geologic movement underground can cause well collapse.

• Nearby wells on neighbors' properties can reduce flow or water quality.
