How deep is the water?

Every person who wants to dig a well, asks the question of how deep the water lies on its site. After he has determined the place where the well will be drilled or a well dug, it will be necessary to determine the approximate depth of the groundwater.

Determination of the depth of the aneroid barometer

The most popular such determinants are aneroid barometer and exploration drilling. For accurate determination, in addition to the barometer, a neighboring well is needed, which should be located near your site.

Depth is determined by the difference in atmospheric pressure. If the water is closer to the surface, then the pressure on the aneroid will increase in a proportion of 0.1 mm. on 1 meter of occurrence of water.

An example of how to determine how deep water is by aneroid barometer:

  • the water in the neighbor’s well lies at a depth of 3.5 m;
  • atmospheric pressure at this well was 751.4 mm;
  • the atmospheric pressure at your intended location for the well is 751 mm .;
  • the difference was 751.4 mm. - 751 mm. = 0.4 mm. mercury column;
  • if the pressure in your area was lower by 0.4 mm. Hg Art., then the water here is 4 meters deeper than 3.5 m. + 4 m. = 7.5 m.

This method of determining the level of groundwater is accurate only in cases where the aquifers are horizontal. If water flows have a slope, which is typical of mountainous terrain, then necessary corrections are made here, which also have approximate values.

What can tell the plants?

At all times, when searching for water, great importance was attached to vegetation, which testified to the proximity of groundwater:

  • In those places where extensive thickets of coltsfoot, there is a high probability of shallow water.
  • Plums, cherries and apple trees do not grow well and dry quickly if groundwater is located closer than 3 meters from the surface.
  • If the plane tree grows away from an open water source, it means that an underground river flows under its roots.
  • Oaks are found in places where there is a high standing of groundwater. Singly they grow where water veins intersect.
  • Alder with willow feel good over aquifers, leaning toward its course.
  • For the Chuvash as a pointer to the close occurrence of water has always served sorrel.

Plants not only indicate a place for a well, but also “inform” us by their presence at what depth of water:

  • under cane water is 1.5-3 meters;
  • under the reeds - 1-2.5 meters;
  • under the polynya - 3.5-5.5 meters;
  • under sarsazan - no more than 3 meters;
  • under the burial ground - 11-24 meters;
  • under yellow alfalfa - 1.5-2 meters;
  • under the black poplar - no deeper than 3 meters.

The trial exploration drilling method will already show exactly how deep the water beds are. But due to the fact that this is the most costly method, it is used when drilling at a depth of 10 meters. When searching for water at a greater depth, the prices for this method increase sharply.
