Factors that affect Water Well Drilling Cost

by | Oct 25, 2022

The installation of a domestic water well undoubtably has a number of benefits. In fact, we’ve written another blog on the topic, which you can find here! Their self-sufficiency is also beneficial for businesses and commercial properties. However, people don’t tend to know that installing a water well is not a one-size-fits all process. There are various factors that affect the cost of the project in question. At Borehole Solutions, a leading provider of geotechnical services across the UK, we wanted to look at the considerations that influence a water well drilling cost.

The Drilling Specifications

Unsurprisingly, a good place to start would be to look at the drilling installation process itself. The depth and diameter of the water well affects how costly your project will be. Consequently, the larger the diameter of the well, or the deeper you drill, then the more expensive it is going to be. These factors impact the water well drilling cost more than any other.

In addition, the type of casing used to line the walls of the well will have an influence on the price. Steel tubing is more expensive than PVC casing, but it is more durable. If you plan on using your well a lot, then it is probably worth investing in materials that are going to sustain long-term handling.

Where is the Location?

For domestic projects, the closer the water well to your home, then the more inexpensive it will be. Conversely, the greater the distance, then more waterline is required. Hence, the project becomes more expensive to carry out.

Water Quality Testing

Once the water well has been drilled, you need to test that the water is safe for consumption. After all, it would be bad news to have your new well installed, only to develop health issues due to it further down the line! We have found that heavy use of fertiliser in the local area can result in high nitrate levels in well water, which is especially dangerous for children and the elderly.

It is no shock that untested water can lead to nausea and diarrhoea, so it is crucial to check your well regularly. The price of contamination testing depends on the accuracy that you would like. A home testing kit can be ordered for between £15 and £30. On the other hand, laboratory analysis is much more expensive, but it’s considerably more detailed.


The cost of transportation is something clients often forget to consider. It is no small task for a geotechnical drilling company to transport their rig equipment – often costing hundreds, if not thousands! However, if your project is local, then you will save a lot of money on transportation costs. Thus, this shows how individual every project is and why the water well drilling cost varies significantly.


It is worth remembering that your private well will require annual maintenance to remain in good working order. This helps to ensure the water doesn’t become stagnant, the pumping system still functions correctly, and that the water is flowing at an appropriate pressure.
