The choice of the season for the construction of a hydraulic structure depends not only on the wishes of the customer, but also on the type and characteristics of the future source. Artesian deep wells can be drilled at any time. For their creation, equipment of increased power is used, and the flow rate does not depend on climatic features. When building Abyssinian wells and sand wells for a private house or summer cottage, the season should be taken into account.
Seasonality and well depth
If the depth indicator of a potential hydraulic structure is less than 25 m, the main factor that affects the selection of the season is the level of groundwater. If it is high, the soil is saturated with moisture. All aquifers that are located close to the surface become full-flowing. This applies mainly to unconfined water layers on which Abyssinians and sand wells are built.
In this case, the possibility of error increases dramatically. It is possible to equip a well with an excellent flow rate when the groundwater level is at its maximum. But in the dry season, the moisture will go away, and the source will lose productivity or dry out completely.
For borehole shafts with a depth of more than 25 m, the level of subsoil water does not really matter. But even in such a situation, in moisture-rich seasons, there will be certain difficulties in performing work. Heavy duty vehicles with drilling rigs will need to travel to the work site via wet ground. If it has become limp from melted snow or prolonged rains, deep ruts will appear, and the cars themselves may get stuck.
Works in summer and early autumn
The months from June to October are considered the best time to create shallow wells. Installation can be done independently, which is facilitated by such factors:
- Dry stable land due to low rainfall and freezing temperatures. Thanks to the comfortable conditions, you can quickly drill a shaft even by hand. The absence of dirt on the roads pleases the drivers of heavy machinery.
- The water mirror in the source is at the lowest possible level. This makes it more likely that an Abyssinian or a well on the sand with sufficient water supply in a dry season will have a high flow rate in any other season.
- Long daylight hours. Summer is the best time to do outdoor work quickly. You can drill or equip wells for 17 hours or more.
At this time, pumping an already drilled source to the sand can be carried out without problems. The newly created well does not receive pure water, but a dirty liquid with admixtures of sand and clay. As a rule, pumping takes from several hours to a day, but few drillers will be ready to devote 24 hours to you. In such a situation, you need to carry out further cleaning yourself. In summer, this is easier to do, since dry soil will absorb a significant amount of pumped out liquid mud.
The owners of the land plots prefer to equip the wells in the autumn period after the harvest, so that the special equipment does not harm the plantings, and during the flushing the crops are not flooded with contaminated water.
The disadvantages of drilling in warm and dry seasons include long queues for work and high prices. Therefore, it is necessary to rely on our own strength or to be determined with the order and performers in the spring.
Also in the southern regions, the land shrinks and becomes dense, which makes manual work unnecessarily laborious.
Drilling in winter conditions
A significant level of soil freezing during severe cold weather makes it difficult to work. But if there is no fierce cold, you can choose this option.
- It is easier to transport equipment and goods without damaging the surface layer of the soil.
- Due to the cold, the borehole almost does not crumble, and its column is not clogged with dirt, which helps to reduce the cleaning time.
- Errors in calculating the water horizon are minimal - the frozen upper water does not interfere with the determination of the subsoil water level and the point of installation of the casing filter element.
The queue of those wishing to acquire a well and the prices of drillers are less in winter than in summer. Thanks to this, it becomes possible to save a lot on the source of water supply. You don't have to think about what to do with the clay solution, which will inevitably appear when drilling a mine, but rely on the action of spring waters. It is recommended to make a well for water in winter in regions with an increased level of subsurface sources, so that they do not interfere with the drilling of the mine.
If you decide to break through the water intake in the winter, by the spring you will be with a well already finished, which will significantly reduce the time of running a water supply system in your summer cottage or garden plot.
The disadvantages of winter drilling include the limited depth of the mine - no more than 25 meters, as well as difficulties during the opening of the frozen soil layer.
Installation of hydraulic structures in spring and late autumn
Professionals do not recommend drilling in the spring months due to the following nuances:
- As a result of floods and melting of snow in spring, the level of groundwater rises, which leads to a change in water layers at a shallow depth. When punching a shaft, this can cause errors in finding the location of the casing filter element.
- Damp and loose earth will create difficulties when drilling and trucks approach the water intake site.
- Wet soil will lead to heavy contamination in the well. It will take a long time and intensive cleaning methods after piercing.
The same goes for rainy autumn. The increased concentration of moisture will significantly complicate drilling in soggy ground. But if you choose when it is better to drill a well for water - in spring or late autumn - the latter option is preferable. There is no flood water, and you can pick up a dry day for work, which happens even in chilly November.
Spring is well suited for arranging pipelines, clearing land, choosing a location for a future borehole, punching method and other work to prepare the territory, which you still have to do.
In most regions of Russia, it is not possible to drill a mine from March to May, in the northern regions - from April to mid-June.
In areas with arid climates, it is also not recommended to drill during the spring season, even if there is no flood. Subsoil waters are unstable anyway, their level is noticeably increased, although visually it may be imperceptible.
Thus, it is necessary to drill a well under water in the summer and early autumn. At this time, the presence of the water layer and its location are determined with great accuracy, the working conditions are more comfortable. It is realistic to plan a penetration in the winter months, if terrible frosts are not expected, and the deadlines are tight. The worst season for drilling due to flooding and eroded access roads is spring.But all this applies only to wells and shallow wells, artesian women are erected at any time of the year.
