Required equipment for the well. How to properly equip a water well with your own hands. Artesian well construction - features

From personal experience, I have been convinced more than once and I never tire of repeating that its efficiency, reliability and durability depend on the quality, correctness of the arrangement of a water well.

Below I will answer the most common questions, describe possible problems that may arise during the construction and operation of a well, and tell you how to better deal with them.

That is why the cost of completing a well cannot be cheaper than 39 thousand rubles - a detailed estimate (look and don't be fooled (

well completion - what is included in the work?

The drilling service implies direct access to the water, installation of the casing and sometimes full pumping of the well. Everything else is the arrangement.

So that you better understand what the cost of well construction is made up of, below I will describe its individual stages and immediately give the average prices for these services in the Moscow region.

Stage	Work carried out	Average cost per MO
Column sealing	Mounting head or borehole cover with adapter	8500-12000 rubles
Caisson installation	Excavation work, installation of a steel, plastic or concrete caisson with a lid, backfilling	22,000-35,000 rubles (depending on the type of caisson chosen)
Pump installation	Selection and delivery of a suitable pump, fastening at the required depth, arrangement of the piping	20,000-25,000 rubles
Water supply to the house	Supply of supply pipes, earthworks (trench depth up to 2 m), installation work	Up to 1,500 rubles per running meter
Installation of the accumulator and pump control unit	Selection and installation of a membrane tank, automation, adjustment	Up to 10,000-12,000 rubles

Additionally, the estimate may include mounting materials, distribution manifolds, a system for automatic drainage of water from the system, valves, fittings.

Helpful advice!

I advise you to always draw up an estimate for the well completion together with specialists in order to be able to immediately refuse additional services, which in your case may be irrelevant, and save money.

What types of wells do we drill

Well construction options

I propose three main methods of well arrangement, each of which is relevant in certain conditions:

• The cheapest way of arrangement. Based on personal experience, I can say that freezing of water in it is excluded if its mirror is at a depth of more than 2.5-3 meters. For winter, the head can be additionally insulated, insulated from direct contact with snow and moisture.

• Bringing water into the house through an adapter. I often come across the fact that people choose this method in order to save money, so as not to buy and install a caisson. And here one problem arises - if it is necessary to service the well, you have to pay extra for earthwork, since the adapter itself is installed at a depth of more than 2 meters from the surface. Therefore, this economy seems to me doubtful

Important!

The choice of the arrangement depends on the type and depth of the well and the intensity of use. Listen to expert advice to avoid additional costs and inconveniences during well operation.

Independent construction of a deep well

Doing a well on the site with your own hands will definitely not work. You will spend a lot of time, money and effort. You can, of course, try to drive in a pipe and make an Abyssinian well, but alas, this is not for long and does not work everywhere.

Without special equipment, tools, and most importantly - experience, you cannot avoid all the mistakes that you can make. I will list just a few of them:

During my practice, I often faced such consequences as freezing of the pipeline in winter, a decrease in the quality of water from the well due to dirt from the surface entering the bottomhole, flooding of the caisson and many other problems.

Helpful advice!

If you are determined to carry out the well completion yourself, I recommend that you find a company that provides installation supervision services. A specialist is sent to the facility, and already under his careful control and taking into account his recommendations, you independently carry out all the work.

HOW TO SELECT EQUIPMENT FOR DEVELOPING A WELL:

• Well type (sand / limestone), its depth, height of the static water level
• The purpose of the well is seasonal or permanent use, irrigation or domestic water supply
• Weather features of the region and the depth of soil freezing, its type
• Type of selected pumping equipment, automation, location (caisson, separate technical room)

I always take into account the geodetic features of the site, we know the geology and then there are fewer problems.

Arrangement of a self-pouring well

A self-flowing well differs from the usual one by an excessively high static water level, which is located above ground level. This is the result of high pressure in the aquifer.

I can tell you with full confidence that there is no point in waiting for simple solutions in this situation.

Self-flowing wells for the Moscow region are an infrequent phenomenon, but sometimes I had to deal with such problematic hydraulic structures and eliminate the consequences.

I know of two options for the development of events:

• Self-flowing occurs only from the wellbore - this indicates that the drillers have done their job well, and water does not enter the annulus. It will be somewhat easier to solve the problem here.
• Spontaneous flow occurs not only from the wellbore, but also from the annulus - this is the result of unprofessional work of drillers or inattention of the chief engineer. A very serious problem with an expensive solution

Column height increase - is the most popular solution to the problem Sometimes, 2-3 meters of pipe is enough to stop spontaneous flow, around which a caisson is set up with a depth of 2 meters, and the upper part is insulated.

If there is a body of water nearby - preferably a river, a stream, I propose such a solution - we climb 2 meters around the column and equip a full-fledged caisson on a good pillow. We muffle the trunk with a head, install pumping equipment in the caisson (you can use a self-priming installation), equip a traditional autonomous water supply.

We make an additional outlet pipe with a valve designed for a certain pressure (depending on the water pressure in the reservoir), to which we connect a flexible hose and direct it into the reservoir.

Thus, we relieve excess pressure and eliminate the risk of water squeezing into the annulus, soil erosion. If there is no reservoir nearby, you need to look for an opportunity to divert water in a natural way to ownerless territories, to artificial drainage.

If it is impossible to eliminate spontaneous flow, and water drainage is impossible, I suggest only plugging the well - "plugging". This is a very complicated and expensive process, and, as far as I know, only a few companies provide such services in the entire Moscow region.

Water is pumped out of the well by powerful compressor units, a clay solution is fed to the bottomhole, and after killing the self-flow, a gravel pad is poured from above. You can also use a special spacer parker to prevent water from rising to the surface.

I do not advise to seal the well with self-flowing tightly, as there is always a risk that water will find its way, and this is a high probability of erosion of the site, undermining of the foundation of finished buildings.

Artesian well construction - features

During my practice, I only came across a few times when people order an artesian well for irrigation. Basically, this type of hydraulic structures is used for arranging year-round autonomous water supply. In this regard, I propose the capital construction of such wells:

• Mandatory installation of a caisson or over a well house + head
• Installation of a diaphragm accumulator, centrifugal pump, automation
• Laying the pipeline in trenches at a depth of 2 meters
• Installation of water treatment systems based on the results of laboratory water analysis
• Installation of auxiliary systems - automatic system drain, drain pump in the caisson

an example of sand well construction and how much it costs

SAND WELL DEVELOPMENT - FEATURES

A well on sand is most often characterized by a lower flow rate in comparison with artesian wells, and a less stable water quality. Therefore, in my practice, in most cases, they are ordered for seasonal use in summer cottages. In this regard, I propose an economical arrangement for:

• Head mounting,buried in a small caisson (1 concrete ring with a hatch) or protected by a small house on the surface

• Installation of a borehole pump

• Laying the pipeline to the house

Below I will compare the costs of the construction of a deep well for limestone and a seasonal well for sand.

Type of work	Limestone well	Well on the sand
Caisson installation	22000-35000 rubles	from 13500 rubles
Installation of pumping equipment	20,000-25,000 rubles	4000-5000 rubles
Plumbing	15000-20000 rubles	1500-3000 rubles
Installation of a water treatment system	From 13000-15000 rubles	Not required
Installation of automation	Arrangement of a well for a permanent residence house I recommend for houses for permanent residence wells with a flow rate of 2 cubic meters of water per hour. If a well for sand or a well gives such a resource, and the quality of the water in it is not bad, then it is not necessary to spend more and drill artesian. I can advise you to familiarize yourself with the situation in your locality, talk to your neighbors, find out what happens to the flow rate in their wells and wells at different times of the year. As for the arrangement itself, I repeat - it must be major, since the main problems arise precisely in winter. The pipeline must be laid at a depth below freezing of the ground. If you have "extra" money, I advise you to install a heating cable just in case - it won't get any worse. But if the installation of the pipeline is carried out at a depth of 2 meters, then the heating cable is unnecessary. From personal experience, I know that the depth of soil freezing in the Moscow region does not exceed 1.8 meters even in the coldest winters, and the average freezing depth is 1.3-1.6 meters. But do not spare the money for the caisson - it will allow you to maintain the hydraulic structure and equipment without extra costs. Can the cellar be used for well construction? Theoretically and even practically - it is possible, but I strongly do not recommend doing this. If you have the problem described above with self-pouring, then you run the risk of completely being left without a residential or utility building. In addition, I am sure that the well construction will be associated with a number of problems (inability to use long casing pipes, difficulties in removing soil, mud), and it will be impossible to use a full-fledged drilling rig. I advise you to drill a well taking into account the SNiP standards - 5 meters from residential buildings, 10 meters from neighboring sites, 25 meters from septic tanks. Summing up, based on my own knowledge and accumulated experience, I recommend that you do not save on well completion, so that later this does not result in additional costs for you. If you set up yourself, you will lose more than you save. Trust real professionals, then you will not face the possible negative consequences described above.

WHAT IS NECESSARY TO DEVELOP A WELL

A water well is the optimal solution for a private house or summer cottage, which allows you not to use water from a centralized pipeline, but to provide yourself with a reliable source of clean artesian water.

The caisson is considered one of the main structural devices. To equip a water well, it is necessary to select the right specialized equipment, which includes a pump, a well head and a hydraulic accumulator (its main function is to change and maintain the required level of fluid pressure in the main well system).

The main guarantee of the effectiveness of a water well will be its tightness. At the same time, the caisson is mounted with a neck, which fits as tightly as possible with a lid. The submersible pump will perform the main function. A stable working pressure for this type of well is 1.8-3 atmospheres.

The caisson is an integral part of the entire structure. Its appearance resembles a standard sealed side of various capacities, which performs a protective function in the water intake system. The caisson is aimed at neutralizing the risk of water freezing or mixing with ground polluted waters. There you can also install filtration equipment, pressure switches, a membrane tank and other structural elements. At the top of the device, a cap is mounted on the neck. During the drilling process, all physical parameters are taken into account, which relate to the diameter, depth of the well, as well as the parameters of the soil (its density, composition, layers and level of groundwater).

The installation of the caisson takes place in a dug hole. In this pit, the casing is mounted; it is welded to the caisson by electric welding. Next, an electrical cable is connected, which is carried out from the pump, as well as a pipe for water outlet. After installation and connection of all structural elements, the caisson is covered with soil (only its lid remains in the open air). Its use in a well allows it to be operated all year round.

Additionally, the well includes the following elements:

• Caisson;
• Pump;
• Hydraulic accumulator (it is an equally important element of the entire well structure, providing comprehensive protection of all systems against water hammer and sudden pressure drops);
• Connection cable;
• A pipe system for connecting a well to a house or watering units;
• Pressure switch;
• Distributor.

During the installation process, a complex of works is carried out, which eliminates the risk of mechanical damage or disruption of the work cycle. At the same time, the organization of the well operation allows not to occupy a lot of useful space in the territory of a private yard or vegetable garden (most of the systems are installed in the well itself).

A concrete cushion is formed under the caisson, which prevents it from rolling back or disrupting its position as a result of the action of soil or groundwater movement.

The main stages of well construction

The well can be drilled in any desired location. However, the optimal distance will be as close to your home as possible. This will eliminate the need for a long pipeline. Consider the fact that the main device - a caisson, will occupy a total of at least four square meters of area.

It is financially beneficial by reducing the amount of consumables and reducing the list of required earthworks. Reducing piping length will require less pump power. Drilling is carried out automatically, which eliminates the violation of the level of the well or its backfilling after this work. Anti-corrosion pipes eliminate the risk of corrosion even after five or ten years of operation.

Installing the caisson

The main requirements for the installation of the caisson is the preparation of the pit, the average depth of which reaches two meters. The exact parameters of the dimensions are determined by the size of the container, however, the width must be at least one meter.

Pump down and installation

The key requirement for pump installation is comprehensive well cleaning before running it. After that, the head is fixed, which is aimed at sealing the wellhead.

Installing a hydraulic accumulator

The hydraulic accumulator ensures uninterrupted water supply. A filled container with a pump will guarantee access to clean water without delay.

Installing systems

This is the final stage after which the water well is ready for operation. The systems include all additional elements that are used for the final connection, including a summer valve and a relay.

Turnkey water supply

Construction of turnkey water wells in the Moscow region

Many residents of modern megalopolises dream of getting closer to nature, away from the bustle of the city, poisoned by air exhaust and traffic noise. But life in a village without the usual comforts turns into real torment. Do not deny yourself basic conveniences - take care of the device for water wells. Order a modern water supply system for a country house from our company and enjoy the comfort!

Arrangement of water wells can be carried out in two versions - summer and winter. The first applies, as a rule, to summer cottages. The resulting liquid in this case is consumed to a greater extent for irrigation and household purposes. Summer construction of a water well does not imply the use of a caisson. However, you will have to manually enable and disable the installation each time.

Winter arrangement of a water well implies the possibility of its continuous operation, regardless of the season. In such structures, the liquid does not freeze and is supplied without interruption.

The device of an artesian well for water is implemented in several stages

Whatever type of arrangement for permanent residence you choose, the scheme of work will be approximately the same. The main differences are in the installation of a caisson or adapter and installation work inherent in this equipment. You will need to decide where to locate the equipment for controlling the water supply system: in the house or in the caisson. The location of the equipment in the caisson allows you to avoid unnecessary noise in the living room and save space. The service life of modern steel caissons reaches 30 years, and plastic ones reaches 50 years.

1. Installation of the caisson or adapter.

Caisson is a waterproof container of a square or cylindrical shape, which provides:

• Reliable protection of equipment from groundwater.
• The well can be used at any time of the year.
• Silent operation of the installation (the caisson absorbs almost all the sound that occurs during the operation of the equipment).

In the process of arranging a well for water, the installation of the caisson should be carried out to the depth of soil freezing. This will completely eliminate the possibility of liquid freezing. The walls of the equipment are at least 4 mm thick, the outside surface is treated with a primer.

Important: when installing the caisson, it is necessary to provide for the laying of heating cables.

2. Installation of the pump and the riser pipe in the well.

At this stage of the water well device, it is important to correctly install the pump and fastening fittings. It is they who provide a high-quality transition to the riser pipe. If the check valve is not built into the pump, it will need to be installed. This part retains water and prevents it from draining back into the well during the period when the pumping equipment is off. The check valve is installed directly on the pump or on the wellhead.

To ensure the fixation of the pumping equipment in the event of an emergency, a safety rope is used. It is attached by a loop that is located on the inner or outer surface of the wellhead.

For reference: If the liquid level in the well does not exceed seven meters, the pumping equipment, not submersible, but surface type, will do its job perfectly. Its installation requires much less labor.

4. Installation of the accumulator.

A hydraulic accumulator is a metal container filled with air or nitrogen, inside which there is a rubber membrane. The device maintains the pressure at the optimum level for operation, reduces the load on the pumping equipment, thereby increasing the service life of the equipment.

The installation of the accumulator can be carried out in the basement of the cottage or directly inside the caisson in order to save space.

5. Installation of the automation system.

A properly installed automation system ensures uninterrupted operation of the entire well. It includes a control panel and a pressure switch for the accumulator.

The control panel ensures full operation of the pumping equipment and prevents it from overheating. Its installation is usually carried out in a residential area. The relay optimizes the pressure both in the accumulator and in the system as a whole. It provides information on the need to turn on the pumping equipment when the pressure drops and turn it off after reaching normal values. The relay is set using a pressure gauge.

6. Laying a pipeline from a well to a residential building.

In order for the residents of a country house to receive water from a well in a timely manner, it is important to lay a special highway in the process of installing such equipment. The installation of the pipe is carried out inside a pre-prepared trench. Its depth should be at least one and a half meters (the data is relevant for all districts of the Moscow region), that is, below the depth of soil freezing.

Directly in front of the place where the line is connected to the cottage, it is wrapped with a special heat-insulating material or a heating cable.

The extraction of clean and tasty water is almost a cherished dream of any owner of a personal plot.
If the water well is already ready, it's time to turn it into a full-fledged source for the "veins" of your home, garden and vegetable garden. In this article, we will consider the well completion with the necessary equipment. Below is a phased work plan.

Caisson installation

This device is designed to ensure sealing of the wellhead from the penetration of sewage and groundwater, and in the winter period serves as its protection against freezing. Externally, the caisson looks like a barrel about 2m high and 1m in diameter with a top hatch, insulated with foam. Inside this container, equipment, a membrane tank, pressure gauges, and pressure switches are usually located to free the premises of the house from unnecessary devices.

• To equip the well with a caisson, you need to dig a hole around it, as wide as the caisson and up to 2m deep. Part of the casing is freed from the soil.
• Then, along its diameter, a hole is cut in the center of the caisson bottom. The prepared apparatus can be installed in a pit through a wellbore. After it has been correctly aligned to the level, the casing is cut and welded to the bottom of the caisson.

• Now you need to connect the pump cable and the water outlet pipe to the finished structure. Then the caisson is filled up to the very cover with soil. The result is a semblance of a closed inspection well.

Installing a water pump

To equip a well in the country with such a device, when choosing its parameters, you need to take into account the depth and diameter of drilling, the length of the general water supply system and the maximum water consumption from the connection points.

The water supply system will operate stably at an operating pressure of 1.5 - 3 atm. The water column of pressure in this range is 30m.

Capacity and maximum water pressure are decisive factors for choosing a pump. His most popular models are from European firms: Water Technics Inc, Grundfos.

• Before installation, an electric cable, a plastic pipe and a safety cable are connected to the submersible pump. The cable is attached to the electric motor, a pipe with a diameter of 25 or 40 mm serves to supply water upward to the tank.
• The safety rope is made of stainless steel in a waterproof sheath. It is designed for emergency lifting of the pump in the event of a pipe break.

• After preparing the pump, you need to clean the well by pumping water until any sediment disappears in it. Inside the well, the pump is placed with full immersion in the water source up to 1 m from its bottom.
• Then the starting protection device of the system and the check valve are mounted. The working pressure in the tank is regulated within 0.9 of the pressure when the pump is started.

Well head device

This element of the well arrangement serves for the following purposes:
... protection of the wellhead from melt water and floods
... protection of the system from groundwater and the ingress of foreign objects into it
... protection against theft of the well and its equipment
... exclusion of freezing of the well part in winter
... increasing the reliability of the pump cable attachment
... facilitating well operation
... realizing the possibility of convenient submersion of the pump by the cover bolts using a winch.

The head consists of a flange, a carabiner, a rubber ring, fasteners and a protective cover. There are 2 eyebolts on the outside of the cover and one on the inside.

The plastic material of the product can withstand a suspended load weighing up to 200 kg, and metal material - up to 500 kg.

• When installing the well head, the casing is cut off, cleaned along with its edge and painted with an anti-corrosion compound. Then, through the head cover, a plastic water pipe and an electric cable are drawn.
• The pump is connected to the pipe, and the free end of its cable is attached to the carabiner through the inner eyebolt of the protective cover. The rubber ring and flange can now be fitted to the casing.
• After placing the pump in the well, the dock cover is installed. For this, the rubber ring and the flange are lifted up to the head cover. Then these three elements are bolted together. The head is ready.

Installing a hydraulic accumulator

It is a metal tank separated by a membrane. The main function of the accumulator is the uninterrupted supply of water from the well to the water supply system. It accumulates water, and this reduces the operating time of the submersible pump and eliminates water hammer when it is started. The accumulator can be installed in the basement of the house or directly in the caisson.

The operating principle of the assembled system is quite simple. The pump turns on and the tank is filled with water. If a tap is open in the house, water does not flow into it directly from the well, but through a hydraulic accumulator.

As water is used in the household, the pump automatically turns on and refills the tank. On the water supply line in the direction of water movement, it is necessary to install a check valve and two drainage drain taps - in front of the tank and after it.

The volume of water for various models of accumulators is from 10 to 1000 liters.

• To ensure the normal operation of the water supply system, an electric autonomous control system is installed. It includes a remote control and a pressure switch to control the hydraulic accumulator and the entire system as a whole.
• Water pipes 32 - 50mm, made of galvanized metal or polyethylene, are laid in the ground to a depth of at least 1.2m. This is a recommendation.
• At the final stage, a bacteriological analysis of the water is done. If necessary, filters are installed to remove bacteria, foreign odors or iron impurities.

For aesthetic reasons, it is possible to decorate the well.
This is done, for example, with colored elements and cement mortar. The original solution will be to decorate the source with pebbles or granite stone. You can make a wooden blockhouse on the aboveground part of the well or plant a willow near.

That's all the wisdom. Now, knowing how to equip a well with your own hands, you can use ecologically clean water all year round, and your family will always be healthy. Good luck to you!

Stages of work on the arrangement of water wells

The technological algorithm for well arrangement involves the following stages:

1. Preparation of the pit and installation of the caisson (or adapter). The devices are firmly and hermetically connected to the casing.
2. Organization of a trench (in accordance with regulatory requirements - in the Moscow region its depth is at least 1.6 meters) for laying pipes from the caisson (adapter) to the building.
3. Installation of a water supply system below the depth of soil freezing.
4. Laying the cable to the building. For these purposes, you can use water pipes.
5. Cutting of the casing and installation of the head (necessary for sealing the wellhead during construction).
6. Installation of the pump with insurance with a stainless steel cable.
7. Installation of automation, manifold and tank.
8. Sealing of caisson entries.
9. Start-up and pressure testing of the water supply system.
10. Well pumping for water. Arrangement of the pipeline.

After that, a complex of commissioning works is carried out. The equipment connects to the system and starts up. The system is tested in various conditions. The final stage of arranging a water well is backfilling the pit with sand, and then with soil.

In this case, it is very important to choose the right equipment. It is necessary to calculate the distance between the building and the well, make calculations of the static and dynamic water levels, well productivity and many other technical characteristics. In addition, when installing equipment, it is important to follow the technology, correctly connect and configure its operation. Therefore, measures for the arrangement of wells should be trusted only by professionals.

Advantages of arranging a well under water by the forces of the company "MOSAKVASERVICE"

• installation of a caisson;
• installation of the pump;
• placement and wiring inside the hydroaccumulator caisson;
• connection of the control system;
• laying of a communication system;
• commissioning works.

Summer well construction option:

We employ well-trained and experienced personnel to complete the well construction. The use of high-performance tools and original equipment helps us to ensure high quality of work. An important role in this is played by constant control of the operations performed, as well as compliance with the current regulatory and technical documents. We carefully study the features of the water supply facility and carefully select the main and auxiliary equipment. This approach helps to increase the life of the well without repair. We carry out the purchase of equipment taking into account the opinion of the customer. We can save the client's time by competent planning, well-thought-out work organization and the use of advanced assembly technologies.

What determines the cost of well construction?

Pricing for well completion is economically justified and is based on objective factors. These include the complexity of the work, the type and productivity of the equipment used, as well as the geodetic features of the site - the physical and mechanical properties of the soil, the level of freezing and groundwater occurrence, the landscape and much more. In addition, the price of equipping a well for water depends on the type and required technical characteristics of an autonomous water supply source. The bottom line also includes other factors, including the cost of equipment (caisson, wellhead, pump, consumables and accessories) and the cost of performing the required work.

We believe that cooperation should be beneficial for both parties, therefore we are implementing a balanced marketing strategy. We can form reasonable prices for the work performed by a well-thought-out work organization, as well as direct partnership with the manufacturers of the equipment and components used.
