How to define a shallow well vs. deep well

This topic is a question that comes up once in a while.  Usually it starts when a customer calls in and requests service for their existing well.  We always ask whether it is a shallow well or a deep well.  A lot of the time the answer we get is “I’m not sure, how can I tell the difference?

Sometimes it is with the size casing.  If it is small diameter, such as 1-1/4″ PVC, that would indicate it is a shallow “well point” as they are called.  If it is 2″ or above, it very well could be a deep well.  Larger casings may also be shallow wells.  Some of the largest diameter wells are very shallow (bored wells).  A 4″ PVC well may be constructed in the same manner as a 1-1/4″ well point, just much larger in screen size and much more expensive.  Most do not drill larger diameter shallow wells due to cost.  The advantage to a larger diameter may be flow or to enable the use of a submersible pump.

The advantage of drilling a small diameter well point is cost.  Another is the fact that you may drill multiple wells and tie them into an above ground centrifugal-jet, end-suction type pump.  This allows wells that produce less than 10 gpm to be utilized without the need for multiple pumps or low flow protection devices, which are needed when a submersible pump is installed on a shallow well.

If you have a well that you are not sure of the difference, we have nice instruments that will quickly tell us what the depth or problem is.  Just give us a call and we will define/diagnose it for you!

Thanks…

About Jody

My name is Jody Anderson. I grew up in Meggett, SC. I have drilled wells all of my life. My grandfather, Joe Anderson started the well drilling in 1958. My father, Andy Anderson, still drills deep wells, geothermal and installs treatment systems. I grew up learning about pumps and why they fail. I love drilling wells and getting muddy, but I really love tearing into a 30 year old pump that my family installed and making it work for a few more years so that the owner may save some real money! I consider myself a self taught water treatment technician, although I have taken many courses throught the NGWA and the SCGWA. I have been a member of the SCGWA since I was a teenager and I am the past Vice President and current board member. I am current Treasurer of the SCGWA. I consider myself well-rounded. I have two sons and enjoy living the rural lifestyle out near Meggett and Ravenel areas. I volunteer for the Boy Scouts of America, and enjoy camping and fishing with my family. Thanks, Jody Anderson
