Self-cleaning of wells

Well is a rather convenient alternative to centralized water supply. Such a source of water on the site is able to solve problems with watering and use of water for household needs. But for proper operation of the well and ensuring its cleanliness, it is necessary to carry out preventive work from time to time. Many owners of summer cottages are thinking about this. To begin with, you should evaluate whether you will be able to carry out such work yourself. Some of them are not difficult, while others require the use of special equipment.

When clogging occurs

If you independently carry out such work, then you will not have to spend a lot on this. When the water pressure becomes weaker, this can be called the first alarm signal. Behind this, as a rule, stagnation followed by gurgling and discharge of turbid liquid. After the system and at all ceases to work. Before cleaning the well, it is necessary to determine the cause of its clogging.

Among the main factors should be noted errors during construction and drilling, as well as problems associated with irregular operation. Water-bearing veins sometimes change their direction, in which case the cause is natural. If the structure does not have protective mechanisms, then more debris falls into the estuary. The cause of blockage is sometimes poor pump performance, as well as lack of maintenance.

To date, there are two main types of wells (with a straight barrel and a filter), and three ways to adjust the work, among them:

• Purging;
• Pumping;
• Washing.

To clean a water intake with a straight barrel is much more convenient, because the equipment can be lowered to the very bottom, and rapid silting is completely excluded. However, any well sooner or later will fail if operated incorrectly.

Using the vibrating pump

The cleaning of the well can be carried out using a special or conventional pump. In this case, it is possible to extract not only garbage with stones, but also sand, and also silt. At the bottom, the pump is installed, and all garbage gets into the pipe and is sucked by the device. Through the pump you need to pass and clean water. If the case heats up, it means that the unit needs to rest. You can use a vibrating pump such as "Kid" for cleaning, if the well is rather shallow. At the same time, the pump can be lowered by 40 m, but not more.

Cleaning of the bailer

The well can be cleaned by bailing. If the pollution is insignificant, and the well is shallow, then this method will do the best. In all other cases, the approach is ineffective. If the depth does not exceed 30 m, you will need a winch. The chute is a pipe on a wire with a mesh at the top. Bottom is the hole.

The pipe goes down, and then rises by 0.5 m and again drops sharply. Inside, water is collected, inside is a metal ball, which rises and falls, closing the hole. This cycle is repeated several times, after the sink is raised and cleaned. To clean the well with this technology could be made more convenient, you should use a tripod. At a time, about 0.5 kg of sand enters the cylinder. Therefore, you can determine how quickly the well becomes clogged.

Mechanized cleaning

The most effective way for deep wells is mechanized cleaning. In this case, two pairs of pumps must be used. Depth will be located at the bottom of the well, it will raise water with silt and mud. The pump feeds water to agitate the sediments.

In order to ensure efficiency, the hose should be shaken and monitored so that the amount of contaminants is not too large. Otherwise, overheating and equipment damage may occur. The device should be selected correctly, its parameters should depend on the depth at which water is located. Pumps for cleaning the well must be vibrating if the depth of the water exceeds 10 m.

Chemical cleaning

Quite often it happens that filters are clogged with hard moods of lime and iron salts. Pressure to knock them out is unlikely to work. In this case, you can resort to critical measures - the use of acids.

The cleaning of the well with one's own hands in this case involves the priming of battery acid, which is used for vehicles. Previously, all the water is pumped out. The acid is left for two days, and the top of the well is clogged with a plug. After this time, the water is pumped out several times, but even after that, it can not be drunk for a month, as it is used for cooking.

Such a liquid is suitable only for household needs and construction. After this cleaning of the well, it is recommended to use water as often as possible, since this will affect the faster washing out of acids. But even in this case, before consuming water, it is necessary to transfer it for analysis to the laboratory, so you will preserve the health of your loved ones.

Sand cleaning

The cleaning of the well from the sand can be carried out in one of several ways. Among them, it should be noted:

• Use of a compressor;
• Excavation of sand by means of pumps;
• Application of chemical methods;
• Use of bailer.

Some of them have been described above. Most often, pumps are used to remove sand. With the help of the first, pure water is pumped into the well, and the second allows pumping out sand and other debris.

You can also apply a compressor. The first cleaning can be carried out immediately after drilling. In this case, the compressor unit is used. This makes it possible to purify the aquifer from the debris that got there during the well completion period.

The cleaning cycle will depend on the depth of the well and takes from a few hours to three weeks. If the drilling was carried out by specialists, the flushing is carried out by the working personnel. If you decide to do the work yourself, you should prepare a compressor that can provide pressure up to 15 atmospheres. You will need pipes that will be connected to each other and inserted into the trunk so that their lower edge reaches the bottom. The caliber of these pipes should be smaller than the diameter of the well.

The cleaning of the well at the dacha using such a technology assumes that the air is injected with a compressor, after which dirty water will be emitted from the well. The first step is to assemble the pipeline and install it in the well, fixing it with a rope. The next step is the installation of a vacuum adapter, which is located on the pipe. Its fastening is carried out by screws. Then, with the help of a compressor, the air is pumped up to the maximum pressure. The hose should be put on the adapter, turn on the unit and pump air into the barrel. This process is repeated several times until clear water begins to flow from the well.

Using a Fire Engine

Sometimes a fire engine is called for cleaning. In this case, a fire hose is used, through which water is supplied under high pressure. At the same time, cleaning takes only 10 minutes. However, this method has its drawbacks, which are expressed in danger and high cost. Strong pressure can damage components and filters. This method is recommended for severe contamination.

Using the lift

Quite often, the owners of suburban areas and areas within the city, where there are wells, are wondering how to use the lift-airlift, if it is necessary to clean the source of water. The method is to use Archimedes' law.

In fact, the well is a vessel with water. In it should be placed a water-lifting pipe, in the lower part of which compressed air is supplied by means of a compressor. A mixture of foam and air forms in the pipe. A water column presses from below, the process begins. It is important to ensure that the water in the well does not end.

Since the lower part of the pipe is located on the sand, it will rise and be absorbed by a water-lifting pipe. It is important to monitor only the water level. Usually the wells on the site are not very deep, therefore a standard vibro pump can be used for their cleaning.

Conclusion

You can carry out the cleaning of the well with acid by yourself. However, it is important to assess the danger of this approach if you do not plan to hand over the water to the laboratory at the final stage. In general, each cleaning technology has its advantages and disadvantages, so they need to be evaluated and only after that to start working.
