A well passport is an official document that indicates the characteristics and features of the source. When drilling a well from an artesian layer, according to the legislation, such documentation is required. If the depth of the source is small, then it is not necessary to draw up documents, but in case of technical malfunctions it will come in handy.
Why issue a passport for a well
Artesian water is a valuable source of the country, so its extraction must be legal and completely legal. In the passport, the water intake source is assigned a cadastral number, which is also entered into the unified state register. It follows from this that the source is registered as an object of nature management.
A passport is required not only to confirm legality, but also for practicality. It lists the technical characteristics that are needed for repair, selection and installation of equipment, calculation of the required parameters.
The document is drawn up by the organization that was engaged in drilling the well and its arrangement. It is imperative to carry out certification. Some organizations start to prepare documents "by default" soon after completion of work. An act of acceptance of the work done and an act of transfer to the customer are also issued without fail.
What information is indicated in the passport of the intake source
Issuing a passport greatly facilitates the future tasks of the owner. There is no single standard form for filling out the data, so the samples of the water well passport differ in appearance. The type of document depends entirely on the driller. But there is a rule that must be taken into account when preparing documentation.
The following information must be indicated in the passport for the water intake source:
- The depth of the aquifer. These parameters must be set by the drillers while drilling the soil.
- Well depth. It can be not only factual, but also dynamic. The specifics of the calculations are different.
- Drilling technology. This process is divided into two types: in 1 string or in 2. In the latter case, the depth is recorded in the passport in order to drill with a large diameter.
- Static water level. It is better to entrust the procedure for measuring this indicator to professionals, since they have the necessary equipment and knowledge. This level is located in the interval from the water surface to the soil surface (provided that there is no water intake for some time). The parameter is calculated only after the water level is restored to the absolute maximum.
- Debit of the device. This is the maximum possible volume of liquid that arrives during the operation of the pumping station per unit of time. The characteristic sometimes plays a fundamental role in the choice of equipment. The pumps should not run "idle", their task is to pump out the volume of liquid that is capable of renewal. If this feature is neglected, the source may be emptied or expensive pumping equipment will fail.
- Dynamic water level at the water intake source. When the pump is started, a drop in the water level is recorded to the point where the pumping out of the unit is compared with the natural renewal of moisture. The driller must fill in this item independently with his own hand.
- The inner diameter of the casing and the materials it consists of.The point is clear enough and easy to understand. The information is important as it will allow you to choose the right pumping equipment for lifting liquid to the surface.
- Detailed description of the downhole filter characteristics. Indicated only in documents for "sand" wells. A detailed filter drawing with mesh parameters, slot diameter and length is appropriate. Knowledge of these indicators will allow in the future, without much hassle, to carry out a planned cleaning of the structure, its repair work.
- Information about the geological and lithological section. Schematic description, where all soil layers are recorded, indicating the beginning and end of their occurrence. It is useful for owners of household plots to know this information during construction work.
It is important that the chemical and bacteriological composition of the water from the well meets all standards. There is a whole list of traits that determine the water suitable for consumption for food purposes.
Only a special analysis will allow to determine the quality of the liquid, the data must be indicated in the passport. For the analysis, a sampling of material is taken and taken for examination. The optimal time to check the quality is two weeks after the end of drilling, when the composition of the fluid returns to normal.
Additional Information
- location of the source;
- what method was used when drilling the well, what equipment was used;
- information on bacteriological analysis and chemical composition;
- the name of the organization that was engaged in the construction and arrangement of the well;
- test pumping data;
- all materials used (hoses, pumping stations, etc.);
- forced adjustments that differ from the adopted project;
- a detailed description of the actual construction of the source;
- description of the filter design;
- plugging and cementing data;
- results of geophysical research.
To simplify the registration process, it is recommended to contact the companies that not only make the well, but also submit all documents at the end of the work, taking into account all the requirements. The cost of services varies widely, depending on the depth and type of soil, and the price also differs in different regions.
