What Are The Factors That Affect Well-Drilling Cost?

by | Jun 26, 2020

Having a water well drilled undoubtedly brings with it several great benefits. In fact, we’ve written a whole blog on the topic – you can find it here! However, what many people fail to realise is that installing a water well isn’t a one-size-fits all process. There are various factors which affect a project’s cost, and the team here at Borehole Solutions, who provide various geotechnical services across the UK, wanted to look at what makes up well-drilling costs.


The Drilling Specifications

It would seem silly not to start with the drilling of the well itself. Both the depth and the diameter of the well affects how costly your project is going to be. Understandably, the deeper you drill the well, or the wider you have it, the more expensive your well will be. These factors unquestionably inform well-drilling cost more than any other. Likewise, the type of casing used to line the well will have an effect on the price. PVC casings are cheaper than steel tubing, but less durable. If your well is going to be getting serious usage, then it’s worth investing in materials that are going to last.


Where Is The Well Being Drilled?

For domestic projects, the closer the well you’re installing to your home, the more inexpensive the project will be. Conversely, the greater the distance from the property, the longer the waterline required and therefore the more expensive the project.


Water Quality Testing

Once the well drilling has taken place, you need to guarantee that the water itself is drinkable. After all, it would be a real kick in the teeth to have your shiny, new well installed, only to develop health problems because of it further down the line! High nitrate levels in well water (which often stem from heavy use of fertiliser, locally) are especially dangerous to the airways of children and the elderly.

Not only this, but untested water well can lead to stomach bugs, nausea and diarrhoea. The price of contamination testing depends on how accurate you want to go. You can order a home testing kit for between £15 and £30. Having a laboratory analysis carried out is obviously more expensive, and can cost into the hundreds of pounds. Borehole Solutions offers a contamination testing service that you can utilise when you have a water well drilled.



Something which clients often forget to take into consideration is the cost of transport. For a geotechnical drilling company to transport their rig equipment is no small task, and can often end up costing hundreds, if not thousands of pounds. On the flipside of this, if the job is local, then you’re not going to be spending much at all on transportation. Thus, again going to show how individual each and every project is, and why the well-drilling cost can vary so much.



It’s also worth remembering that even though they’re fairly self-contained, your private well requires annual maintenance to keep it all in working order. This helps ensure water hasn’t become stagnant (something worth considering if you spend half the year abroad, and half back home, for example), that the pumping system still works well and that water is flowing as it should be, at an appropriate pressure.

Ultimately, several different factors dictate a water well’s drilling cost. As we’ve established, however, factors such as price and materials tend to be the main drivers in determining the financials of an installation job.
