Difference Between a Well and a Borehole. When someone starts looking into groundwater extraction, it is common to come across terms such as well, borehole or drilling. Although they are often used as if they meant the same thing, there are actually important differences between them.

Understanding the difference between a well and a borehole will help you know what you really need before requesting a quote or starting a project.

What is a water well?

A water well is a groundwater extraction system created in the ground to access underground water. It can be used for domestic, agricultural, livestock, industrial or irrigation purposes.

Traditionally, wells were wider and less deep excavations. Today, however, most groundwater extraction systems are carried out through drilled wells, as they allow access to greater depths and can adapt better to the characteristics of the terrain.

What is a borehole?

A water borehole is a deeper and more technical drilling, usually with a smaller diameter, carried out using specialised machinery.

It is especially used when water is found at greater depths, when the ground is hard or rocky, or when a specific flow rate is required for the intended use.

In practice, many companies and professionals use the word borehole to refer to a deep drilled well.

What is drilling?

Drilling is not the well itself, but the technical process that makes it possible to create one.

In other words, drilling is the work carried out in the ground to create the well or borehole. It includes the use of specialised machinery, the choice of drilling system, casing installation, well cleaning and, where necessary, pump installation.

Difference between well, borehole and drilling

In simple terms:

Well: the final groundwater extraction system that allows underground water to be obtained.

Borehole: a type of deep drilling, usually more technical and narrow.

Drilling: the process through which the well or borehole is built.

That is why, although these terms are related, they do not mean exactly the same thing.

So, what do you really need?

It will depend on several factors: the depth at which the water is found, the type of ground, the flow rate required and the intended use of the water.

Creating a groundwater extraction system for a private home is not the same as doing so for an agricultural property, a livestock farm or an industrial activity. Each case requires a prior technical assessment.

In addition, before carrying out a well or borehole, it is also important to take into account the relevant permits and regulations.

Conclusion

The main difference is that the well is the water extraction system, the borehole is usually a deep drilling used to access groundwater, and drilling is the technical process that makes it possible to build it.

If you are considering building a water well, the best option is to work with a specialised company that can study your land, assess the feasibility of the project and advise you on the most suitable solution.

At Pozos de Agua, we carry out wells, boreholes, drilling, pump installation and maintenance of water extraction systems in Catalonia.
