For any settlement, water is required. In order to organize the water supply of the cottage village from the well, it is most advisable to build a water intake site. This includes such components as: three-phase industrial borehole pumps, water metering unit, large storage tanks for clean water and fire reserves, pumps for the second rise of water, so that the water reaches the consumer, automatic equipment.

But such pumps, used to supply the entire cottage village from the well, are very powerful and require a more careful approach to start-up and operation. Starting a powerful three-phase borehole pump of cubes of 10 or 20, a water hammer occurs. And this significantly reduces the resources of the pump motor. When you turn on the equipment, the water rises very sharply and of a large volume. At the same time, well filters can quickly fail. Using a soft start pump will prevent rapid wear of the equipment. So often such a powerful pump does not turn on, use large containers for storing water, equipped with pumps of the second rise.

Water supply of a cottage village using a frequency converter

Description:

When houses are built on an individual basis, neighbors rarely manage to organize the drilling and maintenance of a collective artesian well. More often than not, each owner himself deals with water supply and water treatment. Moreover, he faces a difficult choice.

Water for cottage villages and houses

Whatever method of water supply the owner of the cottage chooses, he will usually have to equip his water treatment system. Even if he manages to connect to the water supply, all the same, the quality of the water is unlikely to “satisfy” the water heater and autonomous heating equipment. Especially if these are imported devices that are very sensitive to the composition of water.

But more often, owners of private houses, as well as the owners of small enterprises in the suburbs, prefer to drill wells. They are collective and individual, artesian and sand. Collective wells are usually drilled during the construction phase of a cottage village. These are always deep wells that can provide consumers with a significant amount of water. The design and licensing of collective wells is usually carried out by the developer. He or the operating organization provides well service and water treatment. Although it happens that along with centralized water treatment, the owners of the cottage also equip their own systems.

When houses are built on an individual basis, neighbors rarely manage to organize the drilling and maintenance of a collective artesian well. More often than not, each owner himself deals with water supply and water treatment. Moreover, he faces a difficult choice.

It is very difficult and expensive to obtain a license for an artesian well, since the sanitary zone, that is, the area on which there should not be any buildings, must be at least 900 m 2, which not every owner has. However, the homeowner has the right to drill a shallow sand well to draw water from the upper aquifer for household purposes. A license is not needed for such a well, although it also has its own sanitary restrictions. But the main problem is that the sand well provides little water, and its quality is poor, therefore, water treatment requires significant costs.

Practice shows that most homeowners are drilling artesian wells, although they are licensed by a few. But in any case, no matter what the well may be, the owner must choose a water treatment system. But understanding the diversity of systems, methods and their effectiveness is not easy for the homeowner. A wide range of equipment is presented on the market, and not only for the private trader, but also for users of collective wells.

Experts told us about the specifics of drilling aquifers and obtaining licenses for them: company representatives shared their experience in organizing water treatment.

Water composition may change.

Is it possible to predict the composition of water before a well is drilled? Does it change over the years? Which wells, sandy or artesian, do the cottage owners prefer? We asked the General Director of RTT JSC to answer these and other questions.

Typically, homeowners “draw” information on the composition of water from their neighbors. The possibilities of scientific forecasting, unfortunately, are limited, because the cadastres reflect old data (until the early 1990s) on well drilling in the Moscow Region and studies of the chemical composition of groundwater. This does not mean that now he is the same. In our practice, and we have been drilling wells since 1993, there have been cases when the composition of water has changed significantly in the well over 7 years. This is due to changes in the total composition of water throughout the horizon.

So, it makes no sense to buy long-term expensive equipment for water treatment, since it may be necessary to completely replace it with a new composition of water?

Personally, I do not share this opinion. In about 10% of cases, the composition of water can change on average over 10-15 years. But with short-lived equipment there will be many problems even for a short period of time.

"Beach" in the Moscow region - high iron content. In our experience, this problem is typical for approximately 70% of water sources. It may happen that the iron was normal or almost normal, and then its content increased sharply. This is due to a change in the nutrition area of \u200b\u200bthe aquifer, when sediment infiltration occurs through buried peaty soils. The second problem of the Moscow Region is the increased water hardness.

Are homeowners still more likely to order sand wells or artesian? What is their average depth in the suburbs?

In the Moscow Region, the average depth of sand wells is 18 m, of artesian wells - 80 m. Nowadays, artesian wells are more often ordered, since they practically do not build small houses. Typically, cottages are built with an area of \u200b\u200bmore than 200 m 2 with three to four points of water analysis. They require about 2.5–3 m 3 of water per hour — only an artesian well will provide such a volume. Sandy gives up to one 1 m 3 / h.

What is the percentage of individual and collective aquifers?

Our company deals only with individual wells. But according to the volume of centralized construction of cottage villages in the suburbs (usually construction companies drill collective wells), it can be judged that this is not more than 10% of the total number of wells. Individual developers have to drill their own well, as neighbors, as a rule, are already provided with water sources. For example, take garden cooperatives. In Soviet times, they were not allowed to build permanent housing there, and the water supply system, if built, was only summer. Now they are building capital houses in summer cottages, this is allowed. And there is nothing left but to drill your wells.

Is it difficult to apply for a well? Who is solving this problem?

For collective wells - a construction organization. For personal - the owners themselves. Obtaining a license for an artesian well is quite difficult. The owner must provide a sanitary zone around the well (at least 30 x 30 m). For sand wells drilled into the upper aquifers, it is required to maintain a distance from the septic tank of at least 30 m. But here in exceptional cases it is possible to coordinate a shorter distance than required by the norm.

If we look at the situation throughout Russia, we will see a massive violation of sanitary standards. There are practically no septic tanks in the villages, instead of them there are cesspools. And water is used without any preparation at all ...

It may happen that according to the cards the water should be in a certain place, but in fact it is not there?

In the suburbs it is very rare that there is no water even at great depths. As an unpleasant surprise, you can probably get very poor quality water. Because of this, there will be too many problems with cleaning and water treatment.

Well Licenses

The cost of water treatment depends on the quality of water, which, in turn, is tied to many factors. What aquifers occur in the Moscow region? What impurities are characteristic for them? What needs to be done to license an artesian well? We asked to answer these and other questions Andrey Mironenko, Head of the Department of Geology and Licensing in Moscow and the Moscow Region, Department of Subsoil Use in the Central Federal District.

In accordance with the law of the Russian Federation “On Subsoil”, for drilling an artesian well, it is necessary to obtain a license for the right to use subsoil. The license is issued not for a well, but for a subsoil plot that has a certain area on the surface of the earth. Accordingly, the applicant must submit a certificate of ownership of land or a lease of land. This is the first.

Further, it is necessary to determine: how much water is needed, what quality, for what purposes, i.e., to calculate water consumption according to the approved standards and coordinate it in the department of water resources in the Moscow region of the Moscow-Oka basin water department of the Federal Agency for Water Resources.

Then you need to get the conclusion of Rospotrebnadzor on the suitability of this land for the organization of the sanitary protection zone of 1 well belt. For an artesian well, in accordance with the requirements of SanPiN 2.1.4.1110–02, the size of the sanitary protection zone 1 of the well’s belt is 60 x 60 m. This section should be fenced, there should be no buildings on it. In exceptional cases, Rospotrebnadzor may agree to reduce the sanitary protection zone, however, it cannot be less than 30 x 30 m.

Then you need to get an opinion on the design of the well in the territorial Center for State Monitoring of the State of the bowels of the Federal State Unitary Enterprise “Geocenter-Moscow”. Based on the required volumes of water, the intended purpose and the hydrogeological conditions of the area, experts will determine what aquifer and depth the well needs to be drilled. In conclusion, there is a geological section, it is indicated at what depth aquifers lie, what is their thickness and water availability. The expected chemical composition of the water is also indicated.

After obtaining a license for the right to use subsoil, the customer turns to a specialized organization, where they draw up a project for drilling a well and coordinate it in the prescribed manner. When a well is drilled, it should be put into operation - for which a commission on state acceptance is created. It is necessary to obtain an opinion from Rospotrebnadzor on the quality of groundwater and the possibility of their use for domestic and drinking water supply. Next, the well should be put on state accounting, equipped with a sanitary protection zone, and a report should be submitted to the state geological examination with an assessment of the operational reserves of groundwater.

All approvals, state registration and assessment of groundwater exploitation reserves will require, of course, considerable costs.

Apparently, the owners of collective wells go such a difficult path?

Of course, but not only them. Owners of private land who do not want to break the law draw up all these documents.

Are there sanitary requirements for water quality?

In accordance with SanPiN 2.1.4.1074-01, it is necessary to determine the presence of more than 40 components in water using three types of analysis: chemical, bacteriological and radiological. Such analyzes began to be done over the past few years, and it turned out that the water of some of the wells did not comply with radiation safety standards (NRB-99). They also found that in some aquifers the MPCs of lithium, strontium, fluorine, and other elements were exceeded.

The most widely used in the Moscow region for water supply is the Podolsk-Shcholkovsky aquifer. The water quality in it almost always corresponds to SanPiN 2.1.4.1074–01, with the exception of the iron content. The underlying Aleksinsko-Protvinsky aquifer is also actively exploited, but in this water there is often an increased content of fluorine, strontium and lithium, and therefore it is necessary to incur large costs for water treatment. But if, say, an enterprise needs a very large volume of water, it cannot get it only from the Podolino-Bolkovsky horizon, so an additional deeper well will have to be drilled.

Doesn't the chemical composition change over the years?

Of course, it is changing - there is water pollution, since there are many industrial enterprises in the region, many treatment facilities that work inefficiently, discharging wastewater onto terrain and into water bodies. In addition, after so many years of restructuring, hundreds of abandoned artesian wells remained, which are sources of groundwater pollution. Currently, in the territories of large regional centers and in their environs, the problem of groundwater quality is becoming the most urgent.

Are there any features for licensing sand wells?

According to Art. 19 of the RF Law “On Subsoil”, a license is not required for drilling a well on the first aquifer from the surface if the horizon is not used for centralized water supply. The compliance of the subsoil plots with the specified conditions for each specific region is established by the Rosnedr territorial divisions together with state authorities of the constituent entities of the Federation. The arrangement and operation of wells on the first aquifer that is not used for centralized water supply is carried out in the manner established by the executive authorities of the constituent entities of the Russian Federation.

There is a dual interpretation of the law. Previously, the law of the Moscow Region On Subsoil and Subsoil Use in the Moscow Region was in force (repealed by Law No. 88/2005 – OZ of 03/10/2005), which allowed the use of groundwater only for the personal needs of the owner of the land. That is, for others, for example, for commercial purposes, a license was required. The federal law does not say anything about this. Although the law of the Moscow Region has been repealed and the new rules have not been established, the regulatory authorities still insist that a license is needed if water is used for commercial purposes. The logic is this: since everyone pays for water, why can merchants who use it in hotels or car washes use water for free? Therefore, businessmen are fined by both the police and Rosprirodnadzor.

What sanitary requirements exist for sand wells?

The same as for the wells. According to SanPiN 2.1.4.1175–02, washing vehicles, watering animals and other activities that contribute to water pollution are not allowed in a radius of 20 m. The place should be chosen in an unpolluted area, remote from cesspools, toilets, fertilizer depots, sewer facilities and other sources of pollution at least 50 m above the groundwater flow.

But to provide such conditions in the garden is almost impossible ....

Of course, impossible. You can be responsible for yourself, and what a neighbor will build within 50 m on his site is only his business. Therefore, in many settlements, the first aquifer from the surface is contaminated with nitrites, nitrates, oil products and other substances of technogenic origin.

But if we talk about violations, they are more characteristic of cottage villages, where homeowners, without a license, drill artesian wells that do not meet sanitary requirements, which leads to pollution of the main exploited aquifers.

Water treatment. Multimedia download aeration type system

The water treatment process always starts with a water analysis. Usually 23 indicators are used, but sometimes an extended analysis is required - by 40 indicators. Although today about 2,000 impurities that may be contained in water have been studied, the same amount of probably there can be inclusions that have not yet been studied ...

But if we talk about the water near Moscow, then the most characteristic impurities are a high content of calcium and magnesium (hardness salts) and a high content of iron. Also in the water there may be an increased or insufficient amount of fluorine, impurities of hydrogen sulfide, ammonium and petroleum products may be contained. Well and, of course, mechanical and organic pollution are characteristic.

There are methods that recommend using certain types of filter media for a given water composition. However, working according to a “template”, that is, according to a certain standard, does not always give the desired effect. When selecting equipment for a particular object, it is necessary to carefully study the composition of water, all its indicators, since some chemical inclusions can impede the work of the most seemingly effective filter media. The use of multimedia filtering media (both in the deferrization unit and in the softening unit), capable of differentially monitoring and leveling “excess” chemical compounds in the water composition, gives a good result. As a result, complex removal of many negative organic and inorganic inclusions can be achieved. It is still important not to concentrate on certain brands, but to select the most effective equipment for a given facility.

But let's start in order. First of all, water requires mechanical cleaning. Our experience has shown that of the three types of common filters (mesh, disk and cartridge), disk filters are the most effective. Such a filter combines the advantages of mesh and volumetric filtration, is easily washed and has an unlimited service life.

Removal of iron, manganese and hydrogen sulfide is possible using reagent filter media with regeneration with a solution of potassium permanganate. In the process of a chemical reaction, iron, which is in a divalent dissolved state, is deposited on the filter loading layer. When washing the filters, the sediment and a less concentrated solution of potassium permanganate is discharged into the local sewage system and eventually gets on the ground, which adversely affects the environment and also interferes with the effective operation of biological treatment plants. In addition, it is unsafe for humans, if during the regeneration period of the filters there will be unauthorized analysis of water.

Alternative possibilities for removing dissolved iron in water and blowing hydrogen sulfide provide reagent-free aeration-type systems. Using a compressor, water is preliminarily saturated with atmospheric oxygen, which enters the filter charge and in the presence of which the oxidation process is more efficient. The use of such systems eliminates environmental pollution. In addition, in the process of aeration, water conditioning occurs, which positively affects its quality.

The next stage of water treatment is water softening, i.e. neutralization of calcium and magnesium salts. Such systems do not differ in a wide variety, although there are, for example, magnetic transducers that are installed directly on the pipe. They magnetize water, preventing crystallization and the deposition of hardness salts. The chemical composition of the water does not change. We believe that it is more efficient to use the traditional method of water softening using ion-exchange resins as part of the downloads. An additional effect is the use of multimedia ion-exchange resins of selective action. For example, if the water has a high concentration of dissolved iron and at the same time it is necessary to remove ammonium impurities, heavy metal ions, humic substances, and aluminum.

It is also justified to include a cartridge charcoal filter in the equipment, which has the function of a sorption filter and is able to prevent the chips of the filter load from entering the water circuit.

To disinfect water, we put an ultraviolet sterilizer as an element of water treatment. This is necessary if there is a risk of water contamination, confirmed by laboratory tests, especially if water is taken from a well or shallow wells.

Some types of hazardous inclusions can only be filtered using reverse osmosis systems. As a rule, such a system is installed on a line of water intended only for drinking and cooking. These devices are quite conservative, but they can be supplemented, for example, with a mineralizer to saturate water with certain doses of substances necessary for health.

Some companies try to impose an excessive set of equipment without explaining to the customer that there are more optimal inexpensive options for a water treatment system. There are companies that offer a full range of systematic after-sales service. We are trying to install such water treatment systems that have optimal functions for this facility and generally do not require service. Or, at least, we try to minimize the worries of the cottage owner about the water entering the house.

Integrated water softener

In the water treatment market, softeners with monodisperse gel strongly acidic cation exchange resins of leading world manufacturers are currently used. Such resins have extreme chemical and mechanical resistance, high exchange capacity. These are reliable filters that perform one function well - water softening.

However, for an individual user when there is no centralized water purification system, as a rule, it is necessary to solve the problems of eliminating several types of pollution. An integrated system perfectly copes with such cleaning. The loading uses a mixture of resins, which allows you to remove hardness salts, and iron, and manganese in one bottle. Therefore, the system of integrated water treatment, in my opinion, can be considered the most effective filter.

Water treatment. Pressureless aeration systems

In cottage villages where water is intended for a large number of consumers, there are two ways to approach the issue of water treatment. You can put an individual system in each house - before this method was very common. But in the last two or three years, they began to actively install water treatment systems serving the entire village.

This allows not only to reduce the cost of water treatment for each homeowner, but also to centrally solve the problem of effluents, as well as to increase the degree of reliability and resolve issues with regulatory authorities.

In recent years, the state has begun to pursue a focused policy on subsoil use issues. All wells, including individual ones, must be licensed. If there is no common well in the village, then each has its own drilled. This is well understood by the controlling authorities, who come with inspections. Which pushes homeowners to organize collective water intake and water treatment systems.

In the Moscow region, the most common “standard” set of pollution. As a rule, water in a common well is cleaned of iron and hydrogen sulfide. Water hardness in the Moscow region is usually within 10 mEq / l. Although the indicators are rather big, such rigidity can be agreed upon with regulatory authorities. And who wants to improve the water, put in their cottages installations for water softening. Such a scheme (general iron removal and individual softening) is optimal, since not all homeowners agree to bear the operating costs of water softening. Many people prefer to solve this problem themselves. As for iron, very often it is many times higher than sanitary standards. In addition, water can be ironized by one-time capital investments at no additional cost.

This is how the non-pressure aeration system works, which our company supplies to the market. It allows you to remove iron from water without using catalytic charges. In general, there are different methods for this, for example, reagent, which is almost never used in the Moscow region. Now reagentless methods are widely presented on the market, but most often they involve the use of pressure aeration with catalytic loading. The method is effective, but the catalytic load, most often, lasts no more than two or three years, then they must be changed. And if there is hydrogen sulfide in the water, then the service life is even less.

The principle of operation of our system is the same as the schemes with pressure aeration, only here the saturation of water with oxygen occurs through dispersing-distribution nodes (DRU). The design of the nodes is such that the water flow is crushed into small drops. As a result, the contact surface of air and water, and hence the saturation of water with air, is greater than with pressure aeration, when air is supplied to the water layer by a compressor (similar to air supply to water in aquariums). Due to the intensive process of saturation of water with oxygen in the DRU, the oxidation of iron dissolved in water is significantly accelerated. Then the water enters the storage tank, and from it, using the pumping station, is supplied to the sedimentary filter system. In the first block, dissolved iron is oxidized to undissolved, and then sedimentary filters collect it. In automatic mode, the regeneration mode is periodically turned on: by the reverse current of water, the accumulated iron is washed off into the sewer.

The advantage of such a system is that it completely copes with the oxidation process, without the use of catalytic charges. It is enough to apply sedimentary loading. For example, we use an inert loading, which does not add unnecessary components to the water and has a low percentage of abrasion - it can work without reloading for more than 10 years.

Our installation is slightly more expensive in terms of capital costs compared to a pressure aeration installation, but it benefits in performance. I already mentioned the reason - in pressure aeration systems it is necessary to restart the catalytic loading. Reloading is a labor-intensive process, often the upper layer of the catalyst is “sintering”, it has to be broken by some mechanical devices (scrap, etc.), which leads to breakdowns of the central distribution pipe or filter neck. Such systems can be chosen by developers who are not involved in servicing villages. And for operators, our system is preferable.

Excerpt

Modern water supply systems of cities and populated areas are complex technical systems that ensure the reception of natural water, its purification with subsequent supply and distribution of water to consumers. The most common are multifunctional water supply systems designed for drinking, domestic, household, industrial and fire water supply.

In this regard, an important task in the design of water supply is its proper design. The purpose of this graduation project is to study the water supply of the village.

To achieve the goal, it is planned to solve the following tasks:

- to study the systems of water intakes, water pipelines and water supply networks;

- to study the existing methods of purification of water supplied to the consumer;

- make the necessary calculations;

- provide rules for the safe operation of water supply systems.

An analysis of literature showed that the annual consumption of water is distributed by the main consumers of urban water supply systems as follows,%: household and drinking needs of the population - 56 (for cooking, drinking - 30, for washing - 10, for using bathrooms - 30, for flushing tanks - 30); the needs of public buildings - 17; industrial needs - 17; firefighters - 3; urban needs (watering the streets and green spaces; working fountains, etc.) - 1, others - 6 ..

The composition and properties of drinking water for any type of water source, processing method and design features of the water supply network should ensure epidemiological safety, chemical composition harmlessness and favorable organoleptic properties. Technical and hygienic requirements and standards for drinking water are regulated by GOST 2874-82 and SanPiN 4630-88.

Average daily water consumption serves as a starting point for determining the estimated water consumption, which is necessary to meet the needs of the population at any time of the year, month, week, including the day of greatest water consumption.

The parameters of the water supply structures of the water supply systems of cities and populated areas are calculated for a certain billing period, which may include several stages of construction, taking into account the prospect of the city's development and improving the level of improvement of water consumers.

Water consumption, for the passage of which the elements of the water supply system are calculated, changes during the quarters of the year, months of the season, hours of the day and minutes of the hour.

These fluctuations in water consumption must be taken into account when designing a water supply system with a given level of improvement. Population growth and increase in water consumption rates are predictable. .

Data on the forecast for the development of the city are taken into account in the process of designing new water supply systems by reserving additional areas for the development of certain elements provided for by the priority of construction. Seasonal changes in water consumption are mainly determined by population migration and climatic factors specific to a given location of the city.

The parameters of the water supply systems of the system are calculated in such a way as to satisfy the needs of the population for water during the seasonal cycles. When selecting pumping equipment, and especially in the feasibility study of water pipelines and water supply networks, the short periods of periods of maximum water consumption are taken into account.

Daily and hourly fluctuations in water flow are the result of uneven water consumption in the city. The unevenness of water consumption in the days of the week is due to the way of life of the city and is mainly associated with the alternation of working and non-working days and largely depends on the production profile of the city or locality.

1. WATER INTAKE, WATER DRAINAGE AND WATER NETWORKS

1.1. Water supply systems and schemes

A water supply system is a complex of engineering structures designed to collect water from a water supply source, purify it, store it and supply it to consumers. Water supply systems (water supply systems) are classified according to a number of signs.

According to the type of serviced object, the water supply systems are divided into urban, township, industrial, agricultural, railway, etc.

According to their purpose, water supply systems are divided into drinking water intended for supplying water for household and drinking needs of the population and workers of enterprises; production, water supplying technological workshops; fire-fighting, providing water for extinguishing fires.

According to the method of water supply, gravity water pipes (gravity) and water pipes with mechanical water supply (using pumps) are distinguished.

By the type of natural sources used, there are water pipelines taking water from surface sources - rivers, reservoirs, lakes, seas, and water pipelines taking water from underground sources (artesian, spring). There are also mixed water pipelines.

On the basis of technical and economic calculations, the combined water supply systems are often arranged: economic-fire-fighting, industrial-fire-fighting or industrial-economic-fire-fighting. So, in cities and towns, they usually arrange a single economic and fire water supply. As a rule, two separate water pipelines are constructed at industrial enterprises - a production one and a fire-fighting one.

Combined industrial, economic and fire water supply system.

Life in the country has many advantages - a clean environment, the lack of fuss, eternal traffic jams. About ten to twenty years ago, suburban life had many shortcomings. The most important of them is the lack of familiar comfortable living conditions. It was not as problematic on the outskirts of the city as other communications.

Without water it’s hard to live in a house or even come there from time to time. Not to mention the fact that on my own plot I would like to plant beautiful rose bushes or the same strawberries. Today water supply of the cottage village is a task that is easily solved by specialists of the Savard engineering and construction company. We carry out not only, but also organize the supply of water for entire residential villages outside the city or even in urban areas.

Organize village water supply  in various ways. One of them is to receive water from nearby reservoirs. If there are no rivers, lakes or ponds, you can drill a well. Shallow wells and wells supply water from the upper layers of the soil. Such water in the predominant majority of cases is quite poor quality, contaminated. It must be cleaned without fail using special cleaning systems.

Artesian wells are of high quality water. Water can be delivered to individual cottages from water towers. However, for their normal smooth operation, high-quality equipment is required. Otherwise, accidents will constantly occur.

The project of autonomous water supply for the cottage village

Quality autonomous water supply of the village  impossible without the implementation of design documentation. The project is necessary for accurate calculation of all stages of work. And also for making an accurate estimate. If this documentation is developed by a specialist with extensive experience, this will minimize costs and create truly high-quality communication. We want to note that it can be equipped simultaneously with a water supply system.

The project must indicate not only the location of each object that needs to be connected to the water supply network, but also the cleaning equipment. Without it, it is impossible to obtain high-quality water suitable for human consumption. Our employees will prepare the optimal project and correctly translate it into reality.
