If there is a well on the territory of a suburban area, then this is an excellent alternative to centralized water supply. Such a source of water can solve the problem with irrigation and supply the house with life-giving moisture. However, preventive work must be carried out from time to time, only then the well will be clean and its operation is in order.
Causes of pollution
To carry out such manipulations, you can use one of many methods. The fact that prevention is required is indicated by a less intense pressure of water. This is followed by stasis with gurgling and subsequent ejection of a cloudy liquid. After that, the system usually stops working. Well cleanup should begin by identifying the cause of the contamination. Irregular operation, errors in construction and drilling, and much more can lead to such troubles. Sometimes aquifers change their direction, and the cause will be natural.
If the structure is devoid of protective mechanisms,then more debris will fall into the mouth. Sometimes the cause is lack of maintenance and improper pump operation. There are two main types of wells, the first are straight-bore, the other are filtered. But the well can be cleaned of contaminants by blowing, pumping or washing.
Cleaning wells with a straight hole will be more convenient, as it is possible to lower the equipment to the bottom, eliminating the risk of silting. With regular operation, any well will become clogged sooner or later. If you want to free it from pollution yourself, it is best to use pumping.
Method number 1: using a vibration pump
You can clean the wells with a conventional or special pump that is used for contaminated water. With it, you will be able to pump out a mixture of sand and silt, as well as fine stones. A pump is installed at the bottom, and the debris that is there enters the nozzle and passes through the pump. Through it from time to time it is recommended to pass clean water. If the case becomes excessively warm, this indicates the need to leave the equipment to rest. Using the "Kid" pump, it is possible to clean a standard well if it is shallow, since the equipment can be lowered by 40 meters.
Method number 2: using a bailer
Cleaning of wells can be carried out even in the case when the clogging is insignificant. If drillingwas made shallow, then you can use a bailer. In other cases, its use is ineffective. At depths of up to 30 meters or more, it will be necessary to use a winch, but this method requires a lot of effort from two men. The bailer is a piece of pipe on a cable with a grid. The tool sinks to the bottom, and then rises by 0.5 meters, then drops sharply. Liquid is drawn inside. The cylinder has a metal ball that rises and falls after a few seconds, closing the hole. This procedure must be repeated several times, and then raise the bailer and clean it of sand. To simplify the work, you can use a tripod. For one such manipulation, about 0.5 kilograms of sand will get inside, this allows you to find out how quickly the well becomes clogged.
Method number 3: mechanical cleaning
Sand is also cleaned from wells when drilling was carried out to a considerable depth. In this case, mechanical cleaning is considered the most effective way, where two pumps working in parallel must be used. Deep, equipped with a lower hydraulic seal, is located at the bottom of the well. It will lift pollution and silt up. The equipment, working in pairs, will supply water to lift the deposits under pressure. In order to achieve positive results, the liquid outlet hose must be shaken and ensure that the amount of contamination is not excessively large. If the concentration of sand and silt is too high, the equipment maybreak down. When the owners clean the well in the country, it is important to choose the right pump, its parameters will depend on the depth of the water. If this parameter is more than 10 meters, then you should stock up on a vibration pump.
Method number 4: use a fire truck
This technology involves the use of a fire hose through which water is supplied under pressure. Using this technique, cleaning is done in 10 minutes, but this method can be not only expensive, but also dangerous. Pressure can damage system components and filters. You can resort to this technology with severe pollution.
Method number 5: using an airlift
Cleaning of an artesian well is sometimes done with the help of an airlift, the work will be carried out on the basis of the law of Archimedes. In fact, a well is a vessel with water in which a water-lifting pipe is placed. Compressed air is supplied to its lower part, which allows the formation of a mixture of foam and air. The column of water will put pressure on the pipe from below, and after the process begins, it must be controlled, you will have to make sure that the water in the well does not run out. The lower part of the pipe will be practically on the sand, it will rise along with the water and be absorbed by the riser pipe. The task of the master will be to monitor the water level. Small stones and dirt will be absorbed by the pipe, being pushed out ontosurface.
Cleaning up after drilling
When considering ways to clean wells, you must remember that this manipulation will need to be done immediately after drilling. Installed filters will not be able to retain small particles, from which the water becomes turbid and becomes unsuitable for human consumption. Depending on the depth, the post-drilling process can take from 10 hours to several weeks. If the arrangement of the well was carried out by specialists, then they will have to flush the system on their own. When drilling with your own hands, you can use a compressor with a capacity of 12 atmospheres or more. Among other things, you will need several pipes that are interconnected and installed in the well. Their diameter should be smaller compared to the diameter of the well so that there is some space between the products and the walls.
The upper part of the pipe must be strengthened with a rope before starting work, since under high pressure the structure may be pushed up. A vacuum adapter is put on the pipe, which is fixed with self-tapping screws. The compressor is inflated to the highest pressure, and then the compressor hose is put on the adapter. After the equipment is activated, the air must be released inside. This procedure is repeated several times. If it was not possible to achieve the desired purity with air, you can replace it with water using the same piping system with an adapter. To do this, you need to use a large barrel,which is installed next to the compressor. It fills up with water. The liquid is pumped into the well with the help of a compressor at maximum pressure. You need to be careful, as dirt and foreign objects can fly into the master. Work should not be completed until the container is empty. Cleaning the well from silt and sand in this way should be carried out until the annular space stops throwing out dirt.
Conclusion
If you will clean the well from sludge using a submersible pump, then it is best to use equipment with automatic equipment. Only then will the device turn off when all the water is pumped out.
