Waterwell / Water Borehole

One of the questions most frequently asked of us is,

How much will a private water supply / waterwell borehole cost me?

To answer this question we will have to know more about your intended project and your site.

• The cost of drilling and lining a borehole is typically £60-£100 per metre depending on geology. The single most important factor determining the cost of the borehole itself is therefore, how deep does it have to be?  (We strongly recommend that you get a geological report from the BGS to take the guesswork out of this.)

• Do you wish to install some form of water storage?, i.e. tank, above or below ground. We supply and install tanks of between 1000 litres and 100000 litres capacity. This would add somewhere between £1500 and £10000 to the cost.

• Do you want the water to be for domestic drinking water?. UV units and filtration equipment can add typically another £1500 - £3000 to the cost depending on the size of the household/group wanting the drinking water. If the water contains high levels of impurities, e.g. iron or manganese, this figure can be higher.
  

• Do you require extra equipment, pipe runs, more outlets, irrigation/sprinkler systems etc.?

These are the variable costs, which depend entirely on mother nature and the choices that you make.

The fixed costs are, for example, the mobilisation charge, i.e. the cost of transport of all the drilling equipment to and from your site and setting it all up. This can be between £1200 -£1800 depending on distance/access.

The cost of the borehole pump, controls, wellhead and custom designed chamber (see gallery). Together these can add up to around £2000. We use only industry benchmark equipment, e.g. Grundfos borehole pumps.

Putting together all of the above it can be seen that a shallow (20m) high quality borehole with few extras will cost £5000 to £6000. A deeper borehole, say around 70m will cost around £9000.

We will only charge you for the actual depth drilled. This means that should the geological survey indicate a required borehole depth of, say, 60m, but we find adequate supplies at 50m, then this depth is what you will be charged for, i.e. your outlay will be reduced.

Having said all of that. Our prices are otherwise fixed. Once we have agreed a price with you, it will not change (unless of course, you change what you want us to do)

As with many other things, there are of course ways of cutting costs (and corners). We choose quality and reliability.

What are the running costs?

This depends on the equipment configuration that you install and naturally enough, on the amount of water that you use.

The components of the running costs are

• The electricity needed to power the borehole pump, any booster pump that you may have, and to power the UV unit should you have one installed. All of these together should only add up to a few pence per day.

• The usage of the consumable or renewable elements in your installation, these are e.g. filter cartridges and UV bulbs. Usually these will only need replacing on an annual basis (depending to some extent on the quality of the natural water from the borehole) and again, will add up to only a very few pence per day.
