Yeah, finally you still have to buy the generator (about 100 € from what I could see here or there) and go to the site by car (as a reminder I drive in 4x4) while currently I go on foot.
In addition to not being within my means (I also have difficult ends of the month) it's not very economical all that
NB: yes I said at the beginning of this post that you could lend me a welding group. But it is a short-term loan, for one or two days, the time to drill the probe; not for several months time to dig a well by hand
Do yourself a drilling ram how?

Hold on, I thought about it more, but a few years ago to plant poles in very rocky ground to make shelters for horses, a neighbor (who worked at France Telecom) came to help me with cash big firecrackers: a hole in the crowbar, a firecracker, and you just have to take out the rock powder with a small spoon!
It may not be very legal but very effective!

it is completely legal for a company having obtained the necessary authorization and having trained personnel for
if you want to bring in a specialized company using dynamite, it will cost you more than a generator: even as expensive as having a real borehole ...
of course if you know someone who knows this technique and can provide you with what you need do not hesitate to take advantage
the dynamite is very good for digging in hard rock: you just have to drill a few holes with a percussion drill (still need the generator) and put what is needed inside, and in one boom your hole is dug as in a week of work by hand ...
problem: not easy to have serious information to choose the amount of explosive to put, and how to make the holes to be effective

Forhorse wrote:Thank you for the bernardd links, I learned a useful tip for this kind of project: use a cone whose diameter at the base is greater than the diameter of the tube in order to reduce the friction of the tube in the hole.
Me stupidly I would have machined a cone of the same diameter.
Otherwise by dint of searching the net and learning about the geology, I have, I think, understood the superposition of the layers.
In fact it is the opposite of what I thought, and it makes sense.
As I am at the edge of a river bed (very small at present, but that has not necessarily always been the case) it has corroded the different geological layers.
The supragypsous marls on which I am going to come across are in fact the "floor" of the region.
Green clay is more recent and is therefore above but has been corroded by the river.
The most recent layer is Brie limestone, which was also eroded first.
If I believe the geological sections that I could find from other parts of the department, under the marls there is another older limestone.
What I don't know is the depth of the valley that the river has dug. Currently it is almost completely filled with sediments due to the very low flow of the ru and which must have been so since time immemorial.
So I am going to dig in this mixture of sediments and alluvium, mainly clays and limestones which "sank" more recent layers.
One can imagine that under these slow river aluvions, there are larger aluvions (sand, gravel, pebble) from an older but faster river.
Otherwise, still what I learned about the geology of the corner, it would seem that the sources are generally located at the bottom of the limestone layer, ie at the top of the clay layer (logic)
Since I am approximately 400m from this limestone / clay delimitation, that makes one more clue which makes me think that I am not too badly placed to have water (how that I try to reassure myself not to dig for nothing )
Hello
after having inserted the hose at 10 meters, it is necessary to make the pocket, remove the sand which risks damaging the pump.
so how do we do?
There are several ways I have heard of compressor which can tell us more.
thank you all

to pump the sand there is the airlift: if the borehole drops 2 meters below the water level, if compressed air is sent to the bottom to make an emulsion 10 times lighter than water it can rise 20 meters more high and overflowing on the surface! with the sand! so dig a big pocket at the bottom
It happened near my house with a borehole over 100m: they sent air into their hole for several days: it came out of the water and tons of sand: I shuttled with my car and my trailer to shovel the sand which accumulated on the edge of the small torent which left their drilling

Hi Chatelot and thank you for your response
but for more information what type of compressor is needed?
or do we put the air hose in the hose? tightly sealed connected to a cat's head?
or else we put the hose in the pipe to the bottom and we take out the water and the sand at the same time
who can inform me
I drove a 2 "50/60 pipe with a 70kg ram, 10 meters deep.
2 meters of earth, then 8 meters of gravel, pebbles and sand
with a treepier 5 meters high and a tiller that I modified to lift the ingenious counterweight (70kgs) !!.
I made a hole using an army manual auger at about 2.5 meters in 6 hours.
then with the tiller in less than 4 hours for 7.5 meters by welding two lengths of 2.5m.
but I still have my pocket to go.
I wanted to rent a diaphragm or flap pump according to the name but it is not possible because the pump does not raise the water to more than 7.5 meters so I have the compressor
but there I have no info to pocket and I can not find anything on the net
so I hope that some people will come forward to bring water to my mill (lol)
thank you all and have a good evening on your biz keyboard

Hello unknown26
I see that you have worked well already.
With a 50 pipe, you have to fall on a sheet of water, not surface water (for future flow, right?)
To make the pocket in sand the solution of Chatelot16 seems adequate.
It is obvious that the exit of the air hose, you have to put it at the very bottom under water, and even penetrating a little in the sand to lift it, I think.
By emptying your air tank at once or almost.
There is the sanitation truck that does this very well, but I believe that their pipe is bigger than your well ...
Problem: if you want to make a closed water circuit, for geothermal energy, OK.
But if you want to pump water to 10 m, how do you plan to do it?
You need a submersible pump, 5 cm in diameter, I don't know any.
