determined on the terrain
you have long dreamed of living in nature, and finally you have a plot of land.However, before embarking on the construction of the house, to be thinking about where to take the water - this issue is best solved at the stage of planning the site.Unfortunately, not always possible to connect to the finished line, often have to master the "bosom of the" self.
If neighbors already have wells, a task made easier: you can set the depth at which water occurs, to determine its quantity and quality.Ask how quickly filled the available wells, if fully pump out water, the level at which it is in the dry season.If you are a "pioneer", will have to drill an exploratory well.
clay, sand, loam and other species occur in the earth formations.Some of them are saturated with water (aquifers) and "give" her at the opening, while others consist of impermeable rocks, which do not contain water and do not miss.The layers of permeable rocks have an emptiness, they permeat
But aquifers occur at different depths.Thus, within the Meshchersky lowland they are only a meter from the surface of the two, and in the area of the Klin-Dmitrov Ridge "bury" have two dozen meters.That is the upper boundary of the aquifer is very uncertain."Thickness" of his usually small: up to 40 meters.In this near to the surface horizon dig shallow wells and drilled wells.Water is necessary to search for, and predictions about its presence and depth can be given only in drilled wells and wells.Other methods hydrogeologists not believe it is authentic.The upper horizon is not as rich in water as the bottom, and it is unknown how long found enough water with vigorous consumption - a hundred years, or six months.The bottom, a limestone horizon lies at a depth of 40 to 200 meters.The water here is always there, and a lot of it.
There are three types of groundwater: perched, ground and artesian.Vadose - coming to the surface ground water.For water supply do not use them, since, seeping through the soil, they do not have time to be cleansed of impurities.Stocks perched small and dependent on rainfall.Periodically, they accumulate, they will gradually disappear due to evaporation or overflowing into the deeper layers.
groundwater - water is constantly existing aquifer closest to the earth's surface.They are installed in the well at that level, which is found in nature.We all know they are in the form of springs with clean, cool, delicious water.
Artesian belong to the so-called "discharge" the waters, as if they are compressed, squeezed waterproof layers.Usually located at great depths.If the aquifer is opened, the water pressure to rise above the earth's surface and even form a miraculous fountain.
quality of water that we receive from different depths, very different.In shallow wells and boreholes in rural areas it is periodically "enriched" with nitrites, nitrates, pesticides, herbicides, and so on.What can we say about the water not far from industrial areas!In addition, its active ports microbiological contamination.
Unlike groundwater, the composition of which is constantly updated, the chemical composition of artesian water is more constant.It has no harmful compounds, radionuclides, almost no microorganisms.Often it is virtually sterile.It contains many minerals - they are dissolved in the water, as that has long been under pressure from reservoir rocks.
well or well?
immediately warned that work on the construction of wells subject to compulsory licensing and to get permission to drill is difficult.The construction of the wells is considered to be "private" affair and paperwork in government offices is not required.
And wells, and wells have their pros and cons.Unequivocally say that prefer, you can not - you need to consider all the factors.Some experts believe that even to raise the question correctly.
consult the firms involved in the water supply of country houses, it is not always possible: some will praise wells, others - well, depending on whether they are building themselves.And sometimes we simply have no choice.For example, wetlands necessarily have to construct well as the quality of water in the well will not meet sanitary standards.It is very difficult to get a deep well in hard rock - in these cases, too, to do well.
If the aquifer lies fairly close to 20 meters, usually dig a well, and if he is at great depths, choose well: in this situation, their prices are comparable.
lot of water out of the well not to get, but it will be enough if the daily requirement of no more than one, two cubic meters.This volume will be enough for irrigation and for domestic needs living in a country house.But if you have a big house with a swimming pool and a fountain, lots of plantings and lawns, well all is not enough.In addition, the level of water in it fluctuates, rising in the spring, after the rain, and falling in the dry season.In a very hot summer it can dry up at all.
now on the operation.Urban residents do not always know that well water should always selected, otherwise it will stagnate and the quality of its "deteriorating, there is the so-called" sedimentation. "(However, silt and shallow well can.) But cleaning the well - it's not a big problem, but ifthe water was not enough, we can deepen its rings of smaller diameter. The well is 50 years old, the same warranty period and provide concrete rings.
advantage of the well it is that it is possible to build on the already developed areas - damage and disruption will be minimal incompared to the damage that will cause him heavy equipment used for the construction of wells (mangled earth, spoiled planting, mountain rocks generated).
And finally, "the financial issue." The most expensive costing an artesian well. One meter minimum diameterMoscow today is about 1,900 rubles. It is clear that the larger the diameter and depth of the well, the higher the cost. For example, in the construction of wells "turnkey" depth of 100 m will have to spend about half a million rubles.Well and shallow wells are much cheaper - in the range of 100-120 thousand rubles.
| In general, it is clear enough for the people it is written, but I would like some clarification.I would like to warn readers that the ground water, that is, its presence and level is also quite heavily dependent on seasonal factors, since in general it is the water, lie on the ground surface of the confining layer and therefore its accumulation occurs directly on the area affected by water pressure filtrationwater from the surface, and this rain, melt water, river water, etc. |
second remark, aquitard - a rock impervious to water, usually it is clay.I think I'm even sure, or rather I do know that if you pour water on the clay - it gets wet.The clay may contain just Huge amounts of water, but it will be aquitard!
could, would still continue, but it makes no sense, becauseArticle guru and is not intended, but simply offers a stretch brains.
