Chalk slurry in skip.

This rotary rig is using air flush which not only sends water out of the borehole, but also the cuttings from the drill head are washed out as well
 

​​​WHAT TO EXPECT

As the borehole progresses the chalk is bucketed away to a nearby skip to try and keep the working area as clean as possible.

Yes its the same picture as the first one. This photo was actually taken the day after drilling was completed and the well installed. The water well is housed in a manhole chamber fitted with a Chameleon Cover so that no evidence of its whereabouts are to be seen.
This is the standard of our workmanship, make sure your contractor can do the same. Read our testimonials page to see what our clients say, or arrange with us to go and see one of our installations and have a chat with the client yourself.

This picture shows the drilling rig in operation. Before starting the borehole, we removed the gravel off the driveway and placed down boards to protect the working area. We use spoil from the borehole to surround the drilling area and keep the chalk slurry in one area around the borehole.

I suppose you now want to see the end result of the drilling process. Well here it is!

Rotary rig making a mess

When having a borehole drilled there are a number of factors to take into consideration.
One of the most important factors is the type of drilling rig used, this is dependant on the geology beneath your proposed water well site. Generally speaking if the borehole is shallow (up to 60 metres) and the geology is not solid rock, a shell and auger rig is probably the best option. If the proposed borehole is over 60 metres, or is solid rock, it is probably better to use a rotary rig.
Shell and auger rigs are relatively light weight and can be maneuvered into awkward positions. They do not use any flushing agents such as foam, water, mud or compressed air whilst drilling and as so are ideal for managing the spoil from a borehole. If the borehole is to be drilled on an established property and you don't want any mess at the end of it, make sure you stipulate that you want the site left as you found it.
Rotary rigs come in all shapes and sizes but are usually much heavier and need a much larger area to operate in. Depending on the geology and depth required, you may have to use a rotary rig which will make a mess of an established garden or similar. If the site is on a farm or a new building site, the mess may not be a consideration. Here are a couple of pictures of rotary drills at work to give you an idea of the mess they can make, and then we'll look at a borehole we have completed in a garden.

This is the site of the water well on a garden driveway, next to a brick laid patio area.

Probably not what you'd like to see in your garden or front driveway!
