In suburban areas today decided to drill artesian wells with high-quality drinking water, unlike conventional wells. Neutral well filled "perched" - not very good water. Artesian well, on the contrary, provides:
- crystal-clear liquid;
- with the correct chemical composition, according to laboratory tests.
Plastic pipes for water wells and the wells are different. Such a source settling polyvinylchloride tubes having acceptable characteristics in terms of safety in contact with water.
Drilled independently or team of professional craftsmen, using heavy machinery to undergo soil layers of granite, clay or sand beds.

Characteristics
It decided to use the casing design products made on the basis of several types of materials. They are made of polyvinyl chloride, or PVC. It stands for unplasticized polyvinyl chloride. Harvesting is inert and is classified as plastics.
Both materials are similar to each other and are used equally to casing structures.
PVC pipe.
The main advantage - lower cost compared with polyethylene pipes. Increased fragility - a significant drawback of PVC products. When coarse mechanical damage instantly elements fail, crack, crumble into pieces, if outdoor temperature are negative.
Such trouble can occur in violation of the art of loading and unloading of the material:
- on the basis of the construction;
- to transport;
- during installation.
PVC products are produced with special thread or without it.
Non-plasticized polyvinyl chloride.
Good specifications tubulars. Produced with special thread designed to seal bonding plastic parts together.
Disadvantages:
- overpriced products;
- lack of ring stiffness.
If the depth of the source of drinking water for more than fifty or sixty meters - plastic wall thickness will increase. Otherwise, PVC-U surface is not withstand the soil pressure and will collapse. This affects the cost and weight.
The advantages of plastic pipes for the well
- high corrosion resistance of the material;
- sufficient mechanical strength;
- low weight;
- low cost, when compared to the price of products with metal or asbestos cement pipe structure for the wells;
- easy installation components.
Mechanical strength is possible thanks to high-tech plastic manufacturing process. If we make a comparative analysis of the PVC products are somewhat inferior to the metal, but still they have more advantages.
PVC - ideal for decorating wells: Deep and sandy, on stable (stable) soils.
If the source is being drilled in deep wells that are larger than fifty meters or unstable soils: quicksand, peat, clay soils - it is best to use the metal as a high risk of damage to the plastic wall.
Low weight polyvinylchloride material facilitates the process of:
- transportation;
- loading, and unloading;
- Product sorting special storage shelves.
Blue, immersing, unloading, plastic products are stored, dispense with the use of expensive equipment (forklift trucks, manipulators, cranes and so on).
Speaking of high corrosion resistance, it is difficult to compete with plastic metal pipe.
Material absolutely not oxidized, and therefore, PVC products, which is under land for decades - is not covered with rust, which is very important for maintaining the quality of drinking liquid. Important long-term use of the product and low cost.
How to choose a plastic pipe for wells
The buyer who is not a professional in the sale or purchase of PVC products must pay attention to:
- the presence of the certificate;
- marking structure;
- the presence of the thread.
The certificate - confirmation:
- high-quality products;
- security;
- practicality;
- durability.
Looking at the markings, it becomes clear that this product is designed for installation in an artesian spring, and not into the sewer or heating system. This is very important, because sewer pipes in any case should not be used as drinking water sources.
It is dangerous for the health of all members of the family or a whole village or dacha community, where people are drinking water from a source well-equipped not by the established standards.
Pipes for wells are in blue color, as well as blue, black, but always with a blue stripe.
PVC pipe is intended for the main goal - to increase the durability of the drilled using source. So be sure to pay attention to the strength characteristics of the goods, which are specified in the accompanying documentation.
Taken into account the depth, which is expected to be drilled. Learn pre-how will deepen - is possible by considering a local map and geological exploration of which is carried out before drilling will be carried out.
Experts will provide documents which clearly indicate that the water in the area at the depth of ten meters, twenty meters, one hundred and fifty meters, and so on. In accordance with predetermined parameters and thickness must be chosen.
The deeper the occurrence of water, the thicker wall PVC pipe, which must be installed in the drilled hole. If set to a thin tube well - it does not stand the pressure and burst, the borehole wall will be destroyed, the source becomes unusable.
Casing pipes are required to meet the following requirements:
- PVC pipe ensure complete sealing of the well, to prevent waste water into potable liquid and the appearance therein: twigs, pieces of clay, peat and so on.
- The inner surface in continuous contact with water. Therefore, high-tech plastic material is chosen that does not alter the chemical composition of fluids, does not cause reduction of the quality of drinking water. The water is clean, odor-free, impurities (dirt sand ground pieces).
installation
It is advisable to drill a hole only in the warm time of year, because some plastic classification structures do not withstand freezing temperatures. Masters have to redo the work, clearing the hole of the destroyed plastic, setting in deepening the new material.
Work carried out during the warm days, take place quickly and efficiently. It is advisable to purchase plastic pipes, Screwed onto each other. Of these components will be able to gather the casing, which will last more than fifty years.
Thus possible to establish long casing to a depth of 50-100 m. Water quality at a given depth is excellent, and the PVC pipe cope with the tasks assigned to it:
- element is destroyed ahead of time:
- polyvinylchloride wall cope with the pressure on the ground plastic;
- Water will not change their consumer characteristics.
The pipe is lowered special downhole pump, after which fluid is pumped to the surface in the required amount.
Borehole drilled in quicksand, peat, other difficult soils may silt.
Cleaning plastic casing passes through the established order, using special materials.
Tech products - not plasticized polyvinyl chloride has a larger allowable stress and greater tensile strength compared to HDPE material. The first tube 125 millimeters in diameter, is immersed in a depth of 30 meters, on a plastic wall withstands the pressure of not more than five tonnes.
Pipe installation in difficult terrain - safe event, from a technical point of view. Polyvinylchloride elements characterized by the presence in the thread structure for high efficiency in parts of PVC compound monolithic tube.
Be sure to take into account the load on the wall, because the PVC products can not cope.
