Water is vital for life, and it is essential to have a reliable source, whether at home, or in a business environment. Normally, people would depend on the regular water supply from the main source. However, in cases where you have an empty space on your property, you could opt to have a well. The well could help a lot when you need a reliable source of water. There are two options when dealing with a well, either deepening or drilling a new one.

Well Deepening

This is the process of re-drilling a well that already existed, and it helps to create, more space for water that springs from underground. 

Before the deepening process, the casing might also need to be extended over the ground, which makes it easier to reach the surface. In addition, any wire and piping that was present will be removed prior to the deepening process. When the wire and piping has been removed, then the drilling rig will be placed over the well, and the cleaning process will begin. Usually, the cleaning stage will be the first step, or the old well will be reamed to remove the tool at the bottom of the well. A drilling bit will then be pushed down to commence the drilling process.

Some of the situations that will call for a well deepening include the following;

A Shallow Well.

A hole which has been dug, bored, driven or drilled into the ground for the purpose of extracting water, is a well. A well is considered shallow if it is less than 50 feet deep. A shallow well has a higher rate of contamination due to natural and un-natural ground contaminates.

Low Flow Rate.

When the flow of water in the well is slow, then you might be needed to deepen it, for the sake of reaching the point that springs water with a higher pressure. • When The Well Runs Dry. Water can never dry up, under the ground. It will only dry in a well, if there was a constant use of it, but the level was not deep enough. The water underground normally comes in layers, and if the well dries up, it will be needed to be deepened or new well drilled.

Can I deepen my existing water well?

Before you can deepen your well, It is essential for your well driller to have complete information on existing well. Including, depth, pump location, feet of pipe. Because regulation was not a strict in the past, there may be no information recorded on your old well.

Benefits of Drilling a New Well

With the new well vs. existing well comparison, the new well has its advantages. Here are some of the benefits of drilling a new well;

Access to Fresh Water.

One advantage of drilling a new well is that you will enjoy a stream of fresh water from underground.


The new well is also flexible, whereby; you will be able to shift it to the desired location. Unlike the existing well, which is rigid, and will only be accessed from where it was initially drilled?


The drilling process of a new well is less complicated than the deepening of an old well. Whereby, an existing well will need extra equipments to clean it first, before the drilling process begins, but a new well will only need the drilling machine.


Because of the deepening process, talk it over with your well driller, weighing the financial advantages of deepening your existing well over a new well.

10 thoughts on “Deepening Existing Well Vs. New Well”

  1. This article was perfect for our needs. We have an existing well, and had heard about just deepening it but we weren’t sure. It seems that our existing well is a little shallow, so deepening it would be advantageous. Thanks for sharing a little more information on this subject.

  2. I’ve thought about this a lot this summer. Our water has been ok so far, but I read that some homes a few miles up the road were having trouble with their wells. I didn’t realize though that it can be cheaper to drill a new well than deepen an existing well. We’ll keep this in mind if we start to have problems with our well.

  3. Thank you for pointing out that the casing may need to be extended as well as the ground, knowing to check for that will be very helpful. I didn’t know that a slow flow rate could indicate the need for a well deepening. Very helpful tips, I will keep them in mind when considering to drill a new well or deepen one.

  4. I find this really interesting; the difference between deepening on old well our drilling a new well. I didn’t even know there was an option of deepening an older well. I think when it comes to well drilling I would choose to drill a new one. I like the idea of it being flexible and cheaper, as you mentioned. Putting in a well seems tough so making it as less complicated as possible sounds good to me. Thank you for your great information, I’ll need to tell my dad all about it. They are thinking of putting a new well in. Thanks again!

  5. I also didn’t realize that deepening an existing well was even an option. I have always wanted to live on property with a well, but just need to find the right place. However, I am surprised that it can cost more to deepen an existing water well than just drilling a new one. This info was super helpful. Thank you!

  6. I’ve been thinking about re-drilling one of my wells. I would love to create more space for water to spring. I didn’t realize though that it would be cheaper and easier to just drill a whole new well. This seems like a better investment for me, so thanks for sharing this.

  7. i didn’t know you could deepen an existing well to try and get more water. Is there a guarantee that drilling deeper will produce more water? I would assume that it would be cheaper to extend the existing well, so I was surprised to read that drilling a new well would be cheaper. thanks for the information!

  8. I just bought my new home, and after we moved in the previous owner told us it has a well. I’ll make sure to see how deep it is. That way I can see if I’ll need to deepen it to get more water out of it.

  9. I didn’t know that drilling a new well is a lot cheaper than expanding an old one. I will keep this in mind for any times in the future where I may have an issue with my well. When finding your company, I also recommend searching online for different options.

    1. Hello Eric,
      Excellent question! Owning a water well on tribal land is handled through the Water Code Department only. You still need to acquire a permit even if you are drilling your own water well. They often will require water sample after well is completed. NOTE: Please retain the information about your well including the depth of the pump. If service is required down the road this information is vital.
