The water supply system is an indispensable attribute of any operating structure, regardless of whether it is residential, industrial or otherwise. Unfortunately, not everywhere and always you can get involved in the central highway. Therefore, the construction of a well in an adjacent area or in a basement( you can do so) is a good solution.
Before considering the method of its self-installation, it is worth pointing to a number of points that any owner who decided to equip an autonomous system with water intake in such a way should take into account. It makes no sense to mention that any task must be performed consciously, only then one can expect the desired result.
And first of all, the expediency of using the well as the source.
Advantages of
- Complete independence from suppliers. They often have an accident, then a preventive repair, and we have interruptions with the supply of water. Still, as is known, this service needs to be paid, while the water withdrawal from the well costs the owner free of charge. Naturally, you first need to "invest", but such hydraulic structures pay off fairly quickly, and the cost of installation and equipment is not so high.
- High quality water. This is said not only lazy, but also deaf-mute. If the rust does not rust or there is no noticeable residue in the glass, then we are happy, because the neighbors are much worse. But if we imagine our esophagus as a system of pipes, it is not difficult to understand what remains on their walls. And every day! The water from the well-equipped well is absolutely clean and meets all standards.
- Rationality. If you take water from a nearby pond - then there are great difficulties with the laying of the highway. To equip a well is also a challenge. The pit has considerable dimensions, and if the site is already planted, the root system of many plants is under threat. Plus - sanitary norms, which do not allow to mount this mini-reservoir where it is "more convenient".The well can be drilled everywhere.
But it should be immediately stipulated that not every owner can perform this work on his own, and often under circumstances beyond his control. It would seem, but what about the title of the article, are not we engaged in anti-advertising? In order not to mislead the reader, let us first note the difficulties that you will have to face when drilling on your own. And only after reading, everyone will understand whether it is worthwhile to do it yourself.
And here for those who decide positively, we will briefly and tell you how to do it. It is in general terms, as there are a lot of nuances here, depending on local conditions.
Features
Wells are artesian and "on the sand."The depth of the first is such( from 70 m and more) that you can not drill a hole on your own - you need a technique. Consequently, only the second option is acceptable. There is a big "plus" here - you do not need to run around the authorities to get permission to conduct drilling operations. For an artesian source, this is necessary.
What to consider?
- Water comes from an aquifer located in a sandstone. As a rule, this depth is from 10 to 35 m. You can do it manually if the boulder does not fall on the "path".In this case it is necessary to start anew, shifting to the side. The question is how many times to start?
- Is there such a layer on the site, and will it provide enough water? What will be the production rate of the well? Therefore, it is necessary to make a couple of control drilling, to make calculations. On the experience of neighbors in terms of the depth of the pit, one should not hope. Underground layers have a complex configuration and it is not a fact that if they take water with 12 m, then on our site it will be approximately the same.
- Liquid from such a source may contain different fractions, microscopic suspensions, so its additional purification will be required. But this is not enough. It will be necessary to take a little water from the control pit and take it for analysis( in SES or another licensed organization) in order to find out why it is suitable - for drinking or only for household needs?
- In addition, in such wells, because of the possible contamination of water by microparticles, not every pump model can be used( the risk that it will fail).
If all this is not "scary" and the decision is made, then such a well is able to fully meet all the needs of one family. This source consists of a pipe, which is placed in a drilled pit. Inside it drops the pump, which supplies water. All you need is to connect the well to the building with a pipeline and connect the automation.
Those who consider all this to be quite complicated and unacceptable, you can advise you to contact a specialized organization. The relevant specialists and permits for the artesian spring will be prepared, and the investigations will be carried out and the installation will be carried out. The only advice is to do it best in winter.
Firstly, , the plantations will not be damaged. First of all - beds. After all, it will be necessary to arrange the arrival of equipment, its work.
Secondly , the cost of drilling will be lower. The logic is simple - the fewer customers, the more discounts.
work technology Site preparation
Although it was said that you can drill anywhere, you still need to understand where it is more rational. The answer is simple - closer to home. It is only necessary to provide that the platform for the caisson device( "chambers") in which the well head and automation will be located) will occupy a square with an area of at least 4 m2.
First, you can save a lot on materials. The shorter the route, the fewer pipes, "backfill"( expanded clay, for example), geotextiles, insulation. Yes, and work on digging a trench is reduced.
Secondly, you can take a cheaper pump. If the pipeline has a considerable length, then it needs water not only from the well to raise, but also "push through" the system. Therefore, a more powerful model is needed, and such mechanisms are more expensive.
Drilling
It is done differently. Who is the usual hand drill( analog of the one fishermen are drilling holes) who install a tripod and use either a shock method or an electric motor. Success is achieved not only by diligence, but also by the right choice of tools( drill bit, bur-spoon and a number of others).The type, configuration of the cutting part depends on the characteristics of the ground. In addition, you will need a set of tools, as one tool can not perform all operations.
By the way, a manual drill can "pass" about 12 - 15 meters, although this is not an easy job.
Installation of pipes and pump
To avoid suction of silt in them, the bottom of the well is filled with coarse sand and small gravel. Before this it is cleaned with a bailer. The first pipe is pre-prepared, and in advance, since it needs to be lowered immediately after the drilling is completed. Otherwise, the walls of the hole may begin to crumble.
In its lower part, approximately to a height of up to 15 cm from the edge, perforations are drilled. This will help the pipe "absorb" more water. A filtering grid is installed on the end face.
One knee is clearly not enough, since the optimal length is about 2 - 2.5 m. With large pipes, both assembly and subsequent maintenance will become difficult. They are connected by "screwing", by thread.
Installation of caisson and
equipment It is clear that the well head should be sheltered. And it must also be insulated. What kind of equipment to put in the caisson, each owner decides for himself how convenient, and this issue is described in detail in a separate article. But in practice everything is mounted in the chamber. This compactness simplifies both maintenance and repair.
It only remains to perform a number of other activities. For example, "swing" the well. But this is the topic of another article.
As it becomes clear, there are no big difficulties in the independent arrangement of the well. But a lot of trouble. Before deciding, doing it yourself or hiring experts, you need to carefully calculate everything - material costs, availability of free time.
Board
You can even save money when ordering drilling. If you mount an artesian well( meters 100 or more), it can simultaneously provide water to several houses. Therefore, it is much cheaper to drill and equip it( on a per capita basis).
