Long since a man built cities near rivers and lakes, since the choice was not only in amenities. Now not everyone has the opportunity to settle near the river, but even with the best possible circumstances in the modern world, river water is unsuitable for drinking. If you are interested in a well to give your own hands, then, most likely, this is a burning question and you know for what purposes you will use the produced water.
In this article we will consider:
The depth from which water is extracted determines its composition and taste. Ask your neighbors who have a well, from what depth water is produced from them, how quickly it can be pumped out, ask them to give it a try, let them express their opinion. In some areas, chemical fertilizers may leak into the surface layer of water, or it may be oversaturated with lime, the presence of which can be determined by boiling, after which limescale will appear on the walls of the kettle (or boiler). Such water is not suitable for drinking and for watering the garden! If this happens in your case, then you will hardly want to spend time and money on obtaining technical water, which may render the fertile soil layer unusable. Drinking water will require artesian water, which is located at a depth of about 200 m, and you will not be able to make such a well yourself.
So, if your neighbors have a shallow well with tasty water, you can make a well to give their own hands, hoping that the same aquifer passes on your site. In this case, you only need a well construction “on the sand”, the depth of which can reach 50 m. However, the optimal depth of the well that you can drill with your own hands is within 25 m. From the name of this device it becomes clear that sand is present in this aquifer or limestone. Choose a suitable place, and you can proceed.
To work, you need a tripod with a winch. Such a derrick can be assembled on its own, based on metal pipes or strong logs. A roller is attached at the top through which the cable will pass. At the bottom, in a convenient place, a winch is attached, which will lower and raise the drilling tool, consisting of the following parts:
The small disk
A drill will definitely be needed. Depending on the type of soil, this can be:
Most often, not one, but several types are required Boers, but often all at once, since there can be different soils at different depths.
In the place where you will make a well, you need to dig a hole (pit), the size of the walls of which should be within 1.5 m. In order to avoid shedding their walls strengthen with boards or plywood. Now install a tripod, which, in our case, will serve as a drilling rig, and therefore should be durable and stable.
To perform this operation, 2 people are required, since one person will turn the rod with a pipe wrench, and at this time, the second will need to be hit with a hammer on the rod, in order to break through breed. The process can be made less time-consuming, if two will twist, and another one, or two people, with the help of a winch, will raise and lower the drill so that it will “bite” into the ground with its mass. As the drill is immersed in the ground, it will need to be pulled out and cleaned. When the drill reaches the aquifer, it will become clear as the soil is extracted from the drill. When the desired water level is reached, the well will need to be cleaned of sand and other solid inclusions with the help of a yolka and a flushing pump.
The methods of drilling "on sand" and "limestone" differ not only in the depth of the well, but also in the diameter and size of the casing. To prevent the walls of the well from being sprinkled, it is necessary to use casing pipes, which can serve as ordinary plastic, however, their size should be sufficient for the pump to freely pass through them.
The choice of drilling method is affected by whether the ground is stable. It directly depends on whether it will be necessary to use casing pipes or whether it will be possible to do without them during drilling. In the event that the soil is crumbling, after a couple of meters you need to install a pipe with a shoe, and since the coupling diameter is wider than the diameter of the pipe, such an assembly will hardly enter the shaft and will have to be hammered into it.
If a shallow well is needed, then only a vertically directed drill string can be used. This well can be drilled without a tripod with a lift.
