Features of drilling wells for water.
During the construction of the house, the question of water supply is acutely arose in the lands of land. Of the two options: imported water or drilling of a well, the zealous host naturally prefers to order drilling wells for water here. And that’s right. A qualitatively executed well, drilled by specialists of their business, taking into account technological requirements and the use of specialized equipment, is the key to uninterrupted autonomous water supply in rural areas.
The choice of drilling method and the type of water well depends on the terrain, the depth of groundwater and its quality. There are two types of water wells: filter (sandy) or artesian wells.
Filter wells are arranged at a small depth – up to 30 meters. However, it should be borne in mind that the production of groundwater from the surface layers can be limited by the environmental environment. In some regions, it can be suitable exclusively for technical needs. If water is necessary for drinking and cooking, its chemical analysis should be carried out.
In the case of water between water -resistant layers, drilling well can be to a depth of 90 meters.
Drilling of a filter well is carried out by a dry way. The drill crashes into an aquifer with a sufficient amount of water, then a casing is inserted into the resulting well. A filter column is located on the bottom of the pipe. A filter for water purification is placed in it. The type of filter is selected, focusing on the character of the sand. For this, a test water fence is made.
When arranging an artesian well, drilling is carried out to a depth of 250 meters. Features of the drilling of deep wells consist in a wet method using clay flushing solution, which is necessary to prevent the well -offset of the well. At first, drilling is carried out by a dry method in sand-clay layers. After the boat reaches limestone, the casing is inserted into the well and the drilling continues with the help of water. With the help of a cement solution or clay, a strong cork is formed.
After the well is ready, a water pipe is carried out from it to the house. To use water from the well in winter, the depth of the water pipe is made taking into account the depth of freezing in this region – from 1.5 to 2.0 meters.
