The area I grew up as a kid the first 20m is sand/clay and pumice after that is hard greywacke stone that needs a trycone to drill though, water is almost anywhere in the valley is 30-50m down but the water for the center pivot irrigation system punches through this layer though a few meters of clay then theres a second water table, still pretty bad water so kept going to the third water table about 250 meters down they kept drilling and reached TD 300 somewhere around there.
The gravel that was poured down the well was probably Bentonite. This expands on contact with water and makes a good seal between the bore hole and the casing. Just out of interest are the tubes used to line the well made of PVC or Polypropylene?
I think it is irrelevant whether PVC or Polyprop was used. Both are very stable in the ground. It is only in the air and in particular sunlight (source of uv-light) that PVC may leach chlorine to the environment.
The gravel was not bentonite, it is simply a gravel pack that goes on the bottom of the well up to the point they first hit water. The blue casing is the well casing and a pump goes inside that, thats why the slits are put into the pipe.
Good point! I guess these guys know about that but choose to do it this way. This is the main contractor in the area for drilling wells and they do hundreds of them. It is a necessary accessory for all the small farms around here and even for every house in the countryside. I have never heard of one single accident connected to this work but that does not mean there are none. Perhaps they will see this and comment.
What a great tutorial video. Thank you so much

Ursula west thanks for sharing, How much they charged per meter please?
Were there property line restrictions? It seems like they chose some ridiculously high ground to drill on.

Sorry, I have no idea. It was an Italian company that did it and, unfortunately, my Italian is not great and I did not ask them.

In my area bore drilling goes on upto 1200ft,bastards dig up for 16hrs.
That drill pipe is awful large in diameter just for a water well.
