No, it's forbidden, I said it (with source) on this forum, but where? In addition, if it is really a well in connection with a water table, it would not really make sense, the water collected would go into the water table.
I have serious doubts.
Rainwater ("pure") in a way, we can infiltrate it via various devices, including wells (they must have a waterproof part on the first mother - or 50 cm ...). But I have a doubt - the builder of my son's house, which I think things have been done in order because of planning documents, permits, etc., has installed a "soot" for the water from the drainage of the house [to avoid a sump pump]
This "official" site talks about infiltration wells: http://assainissement.developpement-dur ... luvial.php
The treated water, coming from an all-water tank or from a phyto-purification, must be spread in a drainage trench on the surface (that, I'm sure; I have brought our installation up to standard, with the installation of a phyto-purification ; Aquatiris expertise) ... There, polluting waste wells were legion in rural areas. With indeed, possible pollution of water tables.

Re: Large volume rainwater storage
Yes, I also find, installation well done, taking advantage of favorable circumstances (cellar, gravity overflow, ..).
Especially since it is these few "first m3" which are the most interesting, because they are "alive" and allow to recover the rains of spring or summer as soon as one started to empty them a little at the beginning. watering season. One m3 of storage will make it possible to recover let's say 2m3 of useful water for watering per year (this is an example).
If the storage is larger, the recovery capacity of the last m3 becomes 1m3 / year and per m3 of storage. They are emptied once a year, but whether or not they are already in use does not change the ability of the system to pick up spring and summer rains.

I have serious doubts.
We were talking (at least that's how I understood the question) of a "well" in the sense of a well dug with a certain height of water at the bottom. (And possibly a beautiful coping, ...)
There it is absolutely clear, it is prohibited, like any direct discharge into the water table.
On the other hand, infiltration wells (therefore filled with stones and other filtering materials over a certain height) are authorized, even if they are less and less favored, especially in catchment areas. It's just common sense, there are places (low point, ...) where there aren't really other possible solutions.

An infiltration well is what I called above soak up ...
In short, I would have legislated just the opposite ...

Not ecological a borehole ?? the Pavlovian reflexes of obscurantist ecologists should be stopped!
So not ecological ???

Like what, if we look directly at the pb, as some are specialists here, criticize at all costs, and have forgotten to look at all the problems in fact.
A truth is true, apart from the point of view that you look at it.
You change your angle, and your first truth is no longer true.
And this "stupid" truth is actually one of the best solutions.
Maybe yet another angle to see? well, I think it's not bad that way.
And well done, and well done for explaining the why.

The catchment areas are now protected by perimeters, with special easements. Le Potager du Paresseux is located within such a perimeter. But not the house, which is on another plot, not concerned. And there, even spreading is prohibited. Many perimeters prohibit the use of pesticides (there, I'm easy).
I do not believe that the "infiltration well" should be filled with gravel (we can do this for safety reasons):

Realized in 2019.
Well I checked to be precise
Exactly:
- 9000 euro
- pump at 55m
- borehole at 80 m

No, it does. Your link shows us the "modern" version with concrete nozzles which ensure stability and certainly limit the risks of progressive clogging. But there is gravel around to ensure a larger percolation surface with the ground.
The older version was often a hole filled with various stones and gravel. At least I have known some like that.
