When is the best time to dig a well on the site. Well under water, features of drilling

Well on suburban area is a very important, and sometimes the only source of water. Very often, its location is planned at the very beginning of construction, because the drilling site is of great importance. The quantity and quality of water, as well as the possibility of further maintenance, depend on it. But before starting drilling, you should not only decide where to drill a well on the site, but also consider all possible options use of the produced water.

How to choose the right place for drilling

In many cases, a source of water on the site is needed only to ensure regular watering of the garden or lawn. In this case, there is no need to High Quality, therefore, the main criterion when choosing a place for drilling will be the proximity of water to the surface. This will help save time and money. Some plants can help determine the proximity of a water bed. For example, it was experimentally determined that in places where bird cherry, lingonberry, willow and other water-loving plants grow, the water is at a minimum depth.

It is possible to drill a well to the upper layer of water (perch water) relatively quickly. But such water in most cases will be absolutely not suitable for drinking. In perched water, sand and soil impurities are very often found, which will literally crunch on your teeth. Well, after heavy rains, all the dirt from the surface gets into this layer of water. Therefore, if you need to drill a well in the area that will give a clean and quality water, you need to make your way to deeper water horizons.

Only professional drillers with specialized equipment can perform such work. In this case, it is impossible to accurately determine the proximity of water occurrence. And it doesn’t really matter for drillers where to drill a well, because water is almost everywhere, and an extra couple of meters of drilling doesn’t really matter. Therefore, on this stage you need to correctly choose a place, starting from the landscape and the location of economic facilities.

Landscape and vegetation

Since heavy equipment is always involved in drilling deep wells, it is necessary to provide it with free passage to the site and convenient placement. Minimum size the platform for the location of the truck is 9x4 m. You should also choose an area without trees and wires, since the mast of the drill rises to a height of up to 10 m.

Vegetation around the well can also become a serious obstacle. If the well is shallow, then every autumn, along with rain, the products of rotting leaves will seep into the water. In a deep well, the water is under solid rocks, and rainwater she is not threatened. But the roots big trees over time, they can damage the canal, so proximity to powerful root systems should be avoided.

The landscape is of great importance. If there are hills on the site, then you should not choose a place on the slope and in the lowlands. The location on a hill ensures that during heavy rain the pit will not be flooded. But with silt and mud flows through the production pipe, various bacteria can enter the water, after which it will be necessary to carry out a complex process of source disinfection. In addition, it is very inconvenient to place drilling equipment on slopes. Of course, it is not always possible to find a perfectly flat place, but if the slope of the surface is less than 35 °, then it is considered acceptable for drilling.

Remoteness from polluting objects

But still essential condition when choosing a location for a well is the distance from economic facilities.

By sanitary standards a well or well should be 5 m away from residential premises and 25 m from a septic tank.

Here, the great depth of the well will no longer save, because wastewater can reach the source even along the walls of the pipe. In this case, the water will become undrinkable. Moreover, there is a risk of spoiling the water within a radius of several hundred meters, and then even drilling a new well will not help.

If there are cesspools or landfills on the site, it is not recommended to drill a well within a radius of 50 meters from them. In order not to risk, you need to try to drill as far as possible from the treatment facilities. The most dangerous objects for a well are:

  • sewer drains;
  • buildings for keeping animals (pigsties, chicken coops, etc.);
  • landfills for household waste;
  • garages.

It is enough to move away from the house by the recommended 5 m, because the farther the well, the more difficult and expensive it is to stretch water pipes in a dwelling. Do not forget to also coordinate your actions with your neighbors, perhaps in their plans the construction of household or treatment facilities. Then all your work may be in vain.

Choosing a location for a well is the first but most important step in providing the site with water. Following simple rules, you will provide your home with clean and fresh artesian water for many years!

The problem of high-quality water supply is one of the most pressing needs for homeowners. Often, there is only one way out - drilling a well or digging a well. This makes it possible to organize offline source for drinking water with year-round access.

And after the decision is made, you need to decide where it is better to drill a well: inside the house or outside. After all, both options have their pros and cons.

Where is it better to make a well: at home or outside?

What is the purpose of the well?

In general, it is necessary to think about where it is better to drill a well at the stage of building a house. Those. when the frame of the building has not yet been made and the space allows you to painlessly use the necessary equipment and carry out work. If the house has already been built, then drilling indoors will be very problematic.

To begin with, you need to decide what goals the owner of the site pursues when he sets himself the goal of building a well. In general, there are two options:

  1. Rare use of the source - for example, in summer for irrigation. There is no need to constantly use the well for drinking and other technical needs.
  2. Permanent use - in this case, a full-fledged arrangement of the water supply system is assumed.

In the first case, it would be more expedient to make a well on the street, i.e. near where it will be used. Moreover, it is necessary to take into account the fact that it is much easier to serve it on the street.

It is also worth taking into account the fact that there is no need for constant wiring of communications. If on summer period a temporary hose is connected to the head, then again, it is easier to do this on the street than in the house.

Arrangement

If the second option is chosen, i.e. the well is made taking into account constant use, then you need to weigh all the pros and cons well. A complete arrangement of the source includes:

  • drilling works;
  • organization of the working space for the installation of equipment - a hydraulic accumulator, a filter system, etc.;
  • wiring and plumbing.

Those. it turns out quite a complex set of works.

If you drill a well inside the house, this will give certain advantages:

On the other hand, if you make the source on the street:

  • you will have to dig a pit and install a caisson in it;
  • the casing pipe must be well insulated;
  • electricity must be supplied to the caisson;
  • for the distribution of water supply it is required to dig a trench.

Thus, it will be about two times cheaper to equip a well in the house than on the street. This difference will be obtained if we take into account full complex work, not just drilling.

By the way, if the house has already been built, then the situation will be reversed - drilling inside it will cost more.

How it works in practice

In fact, the question of where to equip the source - inside the house or on the street, is quite common. Although most drillers are inclined to believe that the well should be done on the street. Where did the practice come from, to make a well in the house?

The fact is that when a person builds a house for himself, he is guided by the convenience of living and takes into account the long-term perspective of operation. Therefore, it is often financial side some solutions fade into the background, giving way to efficiency and cost-effectiveness in the long run.

It's another matter when building companies make houses. Here, monetary gain is in the foreground, therefore, if possible, it is saved on everything that is possible.

Therefore, sources are made in the house, precisely because of the cheapness of this approach. But her problems further exploitation completely fall on the future owners. After all, in fact, such wells are not at all designed for long-term use.

If the decision is made to drill indoors, then it is worth considering the option Abyssinian well. Its technology is best suited for use in buildings.

Possible problems

Unfortunately, a well is not an eternal source of water. In addition, it requires periodic maintenance. And, in addition, a number of problems can happen to it:

  • it can become silted up - depending on the type of water carrier and the intensity of use, a significant decrease in debit can occur after 2-3 years of operation;
  • water can simply dry out - sometimes this happens as a result of geological changes;
  • casing problems may occur.

In all these cases, it will require the involvement of special equipment to solve problems. Unfortunately, in a limited space, there may simply not be enough space to prevent the source. This is the main disadvantage of drilling a well in a house. Whereas on the street, any work is carried out without any problems.

And when such problems arise, the owner is most often faced with the need to drill a new well. And this time it's definitely on the street.

Exploitation

If you do not take into account possible troubles with the well and problems in solving them, you can consider the features of operation at different points.

Using a well at home pros and cons:

  • there is no need to build additional facilities - all equipment is located in one place;
  • homestead territory is not occupied;
  • savings on communications.

However, the cons are more significant:

  • constant noise will come from the equipment;
  • indoors will be high humidity, and this leads to the appearance of mold and fungus;
  • very difficult service.

In addition, as already mentioned above, when the need for prevention arises, this will become a serious problem.

We can draw a simple conclusion - although it will be more expensive to equip a source on the street, in the future this decision will become more rational. Still, no one can guarantee the continuity of its work.

Before you drill, you need to conduct a thorough reconnaissance current conditions. This will help not only find the aquifer, but also provide protection from different types pollution, will show where it is better to drill a well. Let's define the main parameters and signs of shallow groundwater occurrence.

A few secrets on how to determine where to drill a well

It is better to drill in lowland areas. Suitable slopes, lowlands, depressions in the territory. Features of the relief will tell you where the aquifer is located under the surface - sudden changes in elevation are an excellent guide. Aerial photography will help track them.

Analysis of existing conditions - an easy way to determine the place

If there are wells, wells, ponds in the district, the result will approach 100%. Analysis of existing communications helps to assess the depth of water, gives an idea of ​​the geological conditions.

You can find out the input parameters by asking neighbors with experience in drilling and operating wells. Information about the presence of wells will be required - it is better to drill away from them.

Subsurface soil will affect water quality

If the site has sandy or pebbly subsurface soil, this is the first sign of the presence of an aquifer. Try digging a hole and assessing the composition and granularity of the soil. High granularity indicates the abundance of moisture below.

Consider the stones found in the ground. A large fraction (more than 10 cm) indicates the inefficiency of drilling operations.

It will be difficult for owners of houses located in areas with layers of sand or pebbles that are close to the surface. It is difficult and inefficient to equip a well in clayey, silty soils. Here the best choice become an artesian well.

There are layers of sandstone, quartz, limestone located under the place of the proposed drilling, which make it possible to calculate the high productivity of the well.

Vegetation and insects will tell you where it is better to drill

If you want to understand if there is water on the site - look at wild plants growing on the site. A good sign will be the presence of broad-leaved plants, trees, reeds and shrubs on the site. Often water is extracted where burdocks and nettles grow - these representatives of the flora have a very long and branched root system, they draw liquid from the depths. The watercourse will also be where there are anthills.

Reservoirs will help you navigate where it is better

If there is a river, a pond, a spring, a stream near the house, feel free to drill a well. However, it is best to try to move away from the coast at least 15 meters when drilling.

How to determine the location for the well to avoid water pollution

It is important not only to determine the place of drilling, but also to make sure that the water during the lifting process is not polluted in any way. To do this, it will be necessary to ensure the required distance from a potential pollutant. We have presented this data in a table:

Summarize

So, to determine the place on the site where it is better to drill a well, pay attention to the following indicators:

  • Is there vegetation nearby and what kind is it.
  • What is the composition of the soil.
  • Are there any contaminants nearby?
  • Under what conditions and by what methods were wells dug nearby.
  • What is the terrain.

The answers to these questions will unmistakably tell you where to drill a well and what technology is best to use. Decided? Call us. We equip a personal water source within 1 day.

Autonomous water source on the land plot- it's like a working stove in the winter in a car. That is, without it, it seems to be as possible, but it is more comfortable with it. After all, with the help of water you can wash dishes, wash clothes, cook dinner and much more. In the absence of your own well, even a bathhouse does not make sense to build. For this reason, most of those who have bought a plot of land do not start building a house in the first place, but look for this vital fluid.

The process of searching for water for a Russian person is very exciting and takes a lot of time as a couple. After all, many of us first try, and then read the instructions. Here, too, it happens that the owner of the site invites a large company. Together and at an accelerated pace, it will dig a huge hole with it or score many meters metal pipes into the ground. Then, without achieving a result, everything ends with a holiday at the end of the work. As a result, the goal was not achieved.

And the owner after that is left with the question: "How is it, my neighbor has water, but I couldn't find her?" And it's true that it's hard to find water, which must necessarily lie under a certain thickness of soil. That's right, it's true, only Earth's crust It is represented by many types of soil, between which there may be more than one aquifer. In addition, these layers (including the aquifer) lie at an angle and have different power (thickness). Therefore, it is not rare that in one area drinking water lies at a depth of 3 m, and in another area, for example, after 50 m, it does not exist at this depth or it is unsuitable for drinking.

In the search for water, experts advise not to rely on luck, but to approach the solution of the problem seriously. In other words, before starting work on the search for an aquifer, you need to clearly know where, when and to what depth to drill a well under water. After all, this will help to avoid many problems in the future, one of which, in addition to those listed, may be a sudden draining of the source.

How deep to drill a well

Before you start drilling a well for water, you need to decide what kind of water quality is required. Yes, depending on the depth groundwater is divided into :

  • Ground- this is the most upper layer water lying between the surface of the earth and a water-resistant layer (for example, clay). Most often, such water has a high content of iron and other impurities, which makes it unsuitable for drinking. On average, such waters are at a depth of 1.5 to 5 m.
  • Interstratal- a layer of water that lies between two aquicludes. It is characterized by increased rigidity, therefore, for domestic use, it is advisable to use water softeners. It is usually colorless, odorless water suitable for drinking. The depth of occurrence of such waters in most cases is 3-15 m.
  • Artesian- a layer of water under impermeable rocks (e.g. limestone). Most often, such water is highly mineralized. As for its taste and hardness, they depend on the nature of the soluble salts. Such water usually occurs at a depth of 50 to 1000 m.

Where to drill a well on the site

In order to avoid that the purchased pipes are not enough or they are purchased in excess, it is advisable to get a map of the aquifers. This map shows the quantity, thickness and depth of aquifers in a particular area of ​​​​a region or city. You can try to get such a card in organizations engaged in drilling wells for water, or in the bodies of the State Geology. Also, this information can be found on the websites of companies that provide services for hydraulic exploration.

In the absence of data in a particular area, you can either focus on nearby areas, or contact special organizations on a fee basis. They will be able not only to find water, but also to suggest where it is better to drill a well on the site.

But in our time, organizations can have different competencies. Therefore, it will not be superfluous to know about some rules for the location of the well on the site:

  • The well should be located as far as possible closer to home. It is recommended to do this in order to save on laying the pipeline. Optimal Distance 3 m is considered, since it contributes not only to avoiding unnecessary expenses, but also to undesirable undermining of the foundation in case of an unusual situation.
  • Well for collecting ground water, should be as possible further away from sources of pollution (cesspool, landfill, etc.).
  • If there is a noticeable slope in the area, it is advisable to locate the well in the middle. Otherwise, you will have to either drill more or overcome puddles, if necessary, approach the source of water.
  • Recommended for drilling rig allocate a platform of 4x9 m. In addition, we must not forget that the drilling mast has a height of at least 10 m. Therefore, trees and electric wires can be a hindrance to her.

When to drill a well

As you know, the level of groundwater varies depending on the season. But to a greater extent, the uppermost aquifers are subject to this, i.e. surface and ground waters. This has little effect on interstratal waters. Therefore, to search technical water you need to decide on the time of year:

  • Spring- not the most the best time for drilling a well. Firstly, the drilling machine can breed a lot of soil on the site. And secondly, spring is the time when the groundwater level is greatly elevated. Therefore, it may happen that by the middle of summer the water in the well will run out, since the main aquifers lay below.
  • Summer- This comfortable temperature, dry ground underfoot and a well-established groundwater level. All these advantages at this time can turn into two significant disadvantages: queues for drilling and poor-quality work due to haste.
  • Autumn- the time when the complexity of drilling a well depends on the month. So, for example, in September the water level is close to summer, and the soil is dry. In addition, by this time the excitement subsides. The next two months are distinguished by some rise in the level of groundwater and slush.
  • Winter- cold, frozen ground and snowdrifts, making it difficult to access the drilling site. These are the main reasons why many people do not want to drill a well at this time of the year. But they forget that winter is the time when you can save a lot on these works.

The main conclusion that can be drawn at the end of the article is that, if desired, water can always be found on the site. The only question is its quality and the cost of the work.

For owners of suburban and summer cottages located in villages without a central water supply, it is necessary to solve, first of all, the problem of providing their own territory autonomous water supply. To be able to operate the system long time, it is necessary to choose the right drilling site, calculate the required productivity of the projected source and decide when it is better to drill a well for water in order to reduce the financial costs of this process.

Before starting to drill a well, it is necessary to determine the location of the aquifer, calculate the productivity of the projected source, etc.

The placement of the well on the site is regulated by the sanitary rules and regulations prescribed in SanPiN 2.1.4.1110-02. By sanitary rules, it should be at a distance of 30-50 m from sewer wells. Before drilling a well in a site, information should be collected about the location of the aquifer on it. There are several factors that can tell you where the aquifer is located on the territory, and make it much easier to find a place for a future well. These include:

  • surface waters;
  • some types of plants;
  • test drilling;
  • geological features of the site;
  • the location of wells on the plots of neighbors.

The best time to drill a well

The optimal time for drilling a well is the spring-summer period.

Traditionally, wells are drilled in the spring and summer. But with the development of technology, this process can be carried out in any season. Today, each site owner himself determines when it is better to carry out work, taking into account the pros and cons of each period. There are several important disadvantages when drilling wells in the spring. Rising groundwater levels due to melting snow and ice make it difficult to correctly determine the level of the underlying aquifer. Difficulties arise with the access of drilling equipment to the site, soil damage through thaw is possible. To keep the boundaries of the mine should be carried additional expenses, since wet soil floats when it breaks through.

The summer season is the best time for drilling and arranging a well for water. Dry soil, positive air and soil temperature, stable groundwater level, good conditions for survey work- all this allows you to carry out the drilling process quickly and with minimal cost. But with all the advantages of the summer season, this time has one significant drawback: a long queue for work. Registration for drilling mines for a private water supply begins in the winter. AT autumn months- September and October - the conditions for punching water wells are no different from drilling them in the summer. At the end of autumn, if there are no prolonged rains, you can drill mines to a shallow depth - no deeper than 25 m. If weather deteriorate, then a partial deepening of the mine is carried out to the level of soil freezing. The subsequent arrangement of the well can be completed in the winter season. Winter drilling in last years gain popularity.

Modern technologies allow at temperatures reaching -20°C.

During this period, the groundwater level is minimal, which allows you to find the aquifer as accurately as possible without additional test drilling. The frozen soil of the site suffers less from heavy equipment. The soil keeps the shape of the mine well, there are no rain and melt waters that complicate the drilling process. The absence of a queue for work and a reduction in tariffs for drilling operations in winter time- This good benefits in order to fulfill them in the cold season and by spring to have a ready-made autonomous water supply system on the site.
