How we can determine the groundwater

Finding a water vein: how do I find groundwater in the garden?

Table of Contents

Anyone who hears or reads the word water vein usually immediately thinks of dowsers. Indeed, they are still trying to find water today. There is not the slightest scientific evidence that it works. Even more: there is not even such a thing as a water vein in our latitudes. Groundwater occurs with us in terms of area. To tap into it, you definitely don't need a dowsing rod, just some knowledge.

Water vein

If you imagine a kind of canal under a water vein that runs underground and has to be drilled in order to pump water through a well, then you are completely wrong. Groundwater does not run in canals or veins. Rather, it is flat and does not flow, but rather moves very, very slowly. Groundwater is available more or less everywhere in Europe. You just have to drill deep enough to tap into it. However, there are certain geological formationswhere the water is found relatively close to the surface.


If one takes into account the knowledge of geology and hydrogeology, then there can be no more talk of water veins. Another aspect of charlatanism is the claim that these alleged veins would then also become one radiation send out. And a much bigger nonsense is that particularly capable people this radiation by means of a Dowsing rod can perceive. To be clear once again: to this day there is not the slightest scientific proof of this. So if you want to drill a well in your garden, you can safely do without using a dowsing rod.

Find water

There are hydrogeologists who commit themselves that if you drill deep enough, you will find water everywhere in Europe. Since the talk about the water vein is simply nonsense from a scientific point of view, such a water-bearing canal does not have to be tracked down first. In principle, in every garden areal Detect groundwater and then also promote. However, the effort required for this can vary. Hydrogeological overview maps are therefore more effective and usually cheaper than the dowsing rod.

Overview maps

These hydrogeological overview maps provide relatively detailed information about how productive the water-containing layer in the earth is. These maps can be viewed, for example, at district offices, city and municipal administrations and the water management offices. With their help, you can first of all basically assess whether drilling in your own garden really makes sense. The inspection is usually free of charge. Printouts are available for a small fee.

Fissured rock

The rock of a water-impermeable soil layer is decisive for the productivity of a possible well. In general, it can be said: the more rugged this rock, the greater the chance of a rich, sustainable well. The rock fissures ensure that there is always enough groundwater flow can if water is taken from the drilled well. Ultimately, they guarantee a reliable water supply.

Plan a well

If you are considering drilling a well in your garden in order to be able to supply the plants with water, you would do well to first consider the geology of your residential area. Areas with the following subsoil are particularly promising:

  • sand
  • gravel
  • fissured rock: limestones, dolomites, basalts, sandstones

If these formations cannot be found in your own garden, it usually makes little sense to want to drill a well - regardless of the water vein. The first step in planning a well is therefore to deal as intensively as possible with the hydrogeology of the subsurface.

Clear indications

In order to be able to determine whether a borehole makes sense, it is of course not necessary to have in-depth geological knowledge. There are other indications, some of which are very clear. If, for example, there has already been a well on the property, there is a high probability that it will be worth drilling again. This also applies if there are wells on neighboring properties. Soil formations usually extend over very large areas. In the vast majority of cases, they are not limited to a single property. It is therefore more than likely that a well on your own property is worthwhile if the neighbor already has one.

Groundwater level

With these findings, however, it has not yet been clarified where exactly on the own property should be drilled. This is precisely why the charlatans try to score points with the dowsing rod by supposedly being able to determine exactly where to drill. A number of independent tests have shown, however, that these are mostly random hits. As a rule, you perish for this Test drilling not around if the basic requirements are right. These test drillings can be made much easier if you know the groundwater level in your region. If you do not come across water at a certain depth, you can save yourself further drilling at this point. You can get information about the groundwater level from your water supplier.

Negative results

If the borehole primarily produces sand and gravel as well as loose rock, you are basically on the right track. There are of course also negative findings. This is especially the case when mainly clay and loam are brought to the surface. Both materials are almost impermeable to water. This also means that no water can flow through them. The prerequisites for a rich well are not given and you can save yourself the further work.

Patience and test drilling

Finding water in your own garden usually takes a lot of patience. Often it does not work without test drilling. On the other hand, it is also relatively common that a hit is landed on the first attempt. This is especially true when the hydrogeological conditions are fundamentally correct. The effort that is required to find water and to establish a well pays off over time in the truest sense of the word - you simply save water fees.

Goodbye water vein

It almost goes without saying that the temptation is great, despite all the effort, to get involved with the man or woman with the dowsing rod. So again: There are no water veins. As a result, there is no radiation to which the dowsing rod could react. If dowsers still succeed, it is mostly because they are using exactly the hydrogeological knowledge that can be obtained anywhere. But even with them, a precision landing is very rare. A water vein is basically not to be found. It all depends on the groundwater.
