Surface drainage system: types and device. Types of drainage systems. It will be dry: types and types of drainage in a personal plot Types and purpose of the drainage system

Drainage systems help to cope with negative influence surface and ground waters. Given engineering solution allows you to divert and collect water that accumulates on the site. Also, a complex of hydraulic structures is necessary for areas with excessively moist soil.

Various types of drainage will not only contribute to proper construction, but also to the normal cultivation of plants. drainage system prevents excessive accumulation of water and eliminates waterlogging of the soil.

Surface drainage: classification

The most effective combination deep drainage with the surface. There are several principles regarding surface drainage, these are pinpoint and linear. The point system contributes to the local collection of melt and rainwater. Such devices should be installed:

under drains;

under existing irrigation taps;

in various doorways;

in other places of local accumulation of water.

Such a catchment can complement the system linear drainage in those places where fast drainage is necessary (terraces, paths, platforms, entrances). For its construction, drains, storm water inlets, storm dampers and ladders are used.

Linear drainage is one of the most common types of dehumidification. It consists, as a rule, of a system of sand traps that trap not only sand, but also small debris carried out by the flow of water, and channels (trays or drains). From above they are covered with removable gratings, which perform both decorative and protective functions. They keep leaves and debris out of the system and help keep vehicles and pedestrians safe. Channels are made of plastic, polypropylene and concrete.

Separation by design features

The following types of systems are distinguished according to their design features: horizontal and vertical. Horizontal drainage consists of a system of gallery or tubular drains, flumes and ditches. With a tubular type, the pipes are combined with layers of filter cake. The layers help prevent clogging of the pipes with a variety of small debris that rises with the waters. Control over the system allows for manholes.

In the gallery type, special holes are made in pipes with a large cross section that allow water to be received. Such drainage is also equipped with sprinkles. Ditches are mainly used in relief areas, where the groundwater level can be maintained at a depth of 1.5 m. stable ground, ditches are special trenches with slopes; in case of unstable soil, structures made of precast concrete are used.

In vertical drainage, the system of deep drains is combined with a common collector. Through him, with pump unit, water is draining. Vertical pipelines, respectively, divert water to a depth. It is worth noting that the drainage should not cross the aquifer supply to prevent deterioration. sanitary norms drinking water.

Underground drainage

There are several types of systems that help protect underground buildings and basements from waterlogging.

Internal drainage allows you to get rid of the penetration of moisture into various underground structures in cases where it is not possible to open the foundation sinuses, based on the operating conditions of the facilities, and when their opening will entail significant financial costs related to the restoration of communications, engineering systems and landscape. Wherein drainage devices can be installed not only on floors, but also on wall structures. Water is discharged into traditional water intakes:

storm drains;

collectors of drainage systems;

cuvettes, etc.

An additional type of drainage used in construction is reservoir. At the base of the structure, the drainage system is laid directly on the aquifer. It is hydraulically connected to a tubular drain, which is located outside the foundation at a distance of about 0.7 m. The reservoir system helps to avoid both groundwater flooding and excessive soil moisture from capillary moisture. It is widely used in the construction of underground structures, which are built on soils with low permeability.

When draining a garden plot, a complex of pipes and structures can significantly lower the level of groundwater. Particular attention is paid to correct installation systems. When constructing an open drainage, it is worth remembering that it must be above the level of the existing common ditch. It allows you to effectively divert water both during rain and when snow melts.

Closed or backfill drainage is a system of pipes covered with rubble. Most often, it is constructed in the form of a Christmas tree, where unnecessary moisture enters the main pipe from the outlets.

Additional drainage systems

Shallow drainage is a system of ditches arranged by drainage excavators. Ceramic and pottery pipes wrapped in synthetic fabric are laid in them. The depth of the trench is from 1.5 to 3.0 m, and the width is 0.6 m.

Radiation drainage can be used for:

establishing water supply from underground sources;

elimination of leakage of contaminants from the sump or storage tank;

interception of leakage of oil products;

protection against flooding of structures or territories.

In addition to the types of drainage described, in construction there is also mole. In this case, the system of drains with non-reinforced walls is evenly distributed over an area with a slope of about 0.04. The service life of the structure ranges from 3 to 5 years. It helps to collect and drain excess water. The system is laid by special drainage mole machines. In this case, the drains are discharged into open or closed collectors.

Depending on the location of the site, the climate and other factors, there is a possibility of its flooding with groundwater. This issue has been known for the past few years. To solve the problems associated with groundwater, a drainage system is being created. There is a certain classification of drainage systems. Consider all the features of each type of drainage system.

General principle of operation of drainage systems

It works quite simply: the created system drains water from various kinds premises and structures. Drained water can accumulate in special tanks or be thrown out behind the site. Groundwater drainage should be carried out to solve the following tasks:

To eliminate the possibility of flooding.
To eliminate the possibility of flooding structures.
In order to extend the life of the building.
In order to prevent the formation of mold and fungi on the surface of the walls.

A drainage system is an extensive system of drainage pipes (drainage, storm water, wells) that are located along or around a building or area that must be protected from moisture.

In general, many drainage systems are simple and reliable, carried out installation work do not lead to high costs, you can create drainage yourself using special materials.

The main types of drainage systems

The most popular drainage systems include the following varieties:

Plastic.
Wall.
Ring.

For the construction of plastic drainage use plastic pipes, which have stiffeners and a large number of small holes, evenly distribute pressure in the pipe, are not subject to corrosion and are easy to transport.

Each type has its own characteristics, which we will discuss in more detail below.

What are the features of ring drainage?

When considering the features, you should pay attention to the fact that they are used to protect basements, dugouts and other premises that are laid in sandy soil.

Annular drainage of the site - drainage systems and is designed to reduce the level of groundwater and drain it outside the site, this type of drainage also solves the problem of removing "excess" water from the soil, which collects in the soil when snow melts and heavy rainfall.

The problem with deepening a building is that the general drainage system may be higher, which means that its effectiveness will be reduced. In order to significantly increase the efficiency of the general drainage system, circular drainages are created.

Important! It is allowed to create open drainage rings in the event that groundwater approaches the building from one side only.

When considering the features of such a system, attention should be paid to the following points:

The bookmark is recommended to be performed at a distance of 5-8 meters to the wall. In this case, you can avoid the likelihood of flooding the building and reducing the strength of the walls.
If the laying is carried out at a closer distance, then more serious measures will have to be applied. Otherwise, there is a chance that water will get under and wash it away.

In other cases, the considered type of drainage, as a rule, is not used.

Features of the organization of wall drainage

Before holding construction works for the construction of sites for various purposes, as a rule, a study of the characteristics of the soil is carried out. The ongoing research allows us to determine, as well as the type of soil, which determines the susceptibility of the base to moisture. If after the study it was found that the base is represented by clay and loamy soil, wall drainage should be created. Its features include the following points:

The surface part of the system is located around the entire perimeter of the building. At the same time, it can be placed at different distances from the wall, which may be associated with a certain width of the foundation and the locations of the wells. The system under consideration has manholes, which significantly increase the efficiency of drainage.
During construction work on the site with various types soil, the creation of wall and ring drainage is carried out. Only in such a case it is possible to significantly reduce the likelihood of erosion of the soil under the foundation.

Wall drainage is used to collect and drain water that comes close to the foundation of the building and thereby prevents basement flooding.

Recently, there have been many different modern materials which significantly increase the efficiency of drainage systems. They are able to filter out large and small particles, thereby eliminating the possibility of clogging the system. That is why many experts recommend using modern polymers when creating drainage.

Features of plastic drainage

Under special hydrogeological conditions, plastic drainage is used. Its application features include the following:

If there is a large and powerful aquifer, then it is practically impossible to find a more efficient drainage system.
If other drainage systems are of low efficiency, then you can also use plastic option execution.
If the aquifer has a layered structure, many types of drainage are not effective.
In some areas, you can find a situation where groundwater is pressurized. An example is the flow of underwater rivers nearby.
If there is a lens directly in front of the building it is also recommended to use the type of drainage in question.

Plastic drainage is suitable for intensive use, most often it is used in areas with a close location of groundwater, near water bodies, in flooded areas.

In addition to the above recommendations for use, one should take into account the moment that they use plastic drainage in case of presentation of special requirements for the dryness of the basement or other type of premises. It's connected with high efficiency, system reliability.

local drainage systems

In addition to the above systems designed to drain water from buildings and plots, attention should also be paid to local drainage. In some cases, they are more suitable for use. We single out the main types of local drainage systems:

At the same time, recommendations should be taken into account that relate to the creation of a system, taking into account the need to prevent the removal of soil from under an already erected structure. The work is carried out by creating small trenches, in which the drainage system is formed, after which they are immediately filled up. All work is phased creation one trench, filling it up and creating the next one.

What is the opinion of experts?

He carried out the construction of a private house on a suburban area. The first time I met with the problems of a high level of groundwater, since the site was in a lowland, near the river. Decided to organize plastic system drainage and it turned out that the choice was right.

I do building design. I know firsthand that groundwater can bring quite a lot of problems. At the same time, it is possible to correctly select the drainage system only after the completion of soil studies. If such a recommendation is neglected, there is a possibility that in basement water will accumulate, dampness will appear in the structure. All this will eventually cause a loss of foundation strength and many other problems.

The problem of draining rain or melt water from the house or excess groundwater from the soil of the garden plot is solved by drainage systems. What types of drainage exist?

First of all, drainage systems are divided according to the method of laying:

superficial (open);
backfill;
deep (closed).

Surface drainage

Surface or open way gaskets by their very name suggests that it is designed to collect water from the surface of the site and the yard, as well as to drain water flowing from the roofs of buildings on the site. Open channels laid around (along the perimeter) of the house divert storm drains from the foundation and the territory adjacent to the house and thereby preserve the foundation, basement and basement from dampness and mold, and the blind area and paths from destruction.

In its turn surface way divided into such types of drainage as:

point;
linear.

Your attention!

These types of drainage systems are different from each other.

dotted surface drainage designed to collect water at strained drain points, these points are closed with metal decorative grilles which prevent large debris from entering the drainage pipes. Water collection points are connected by drainage pipes to one main pipe, which in turn is connected to a drainage well or to a system storm sewer.

Also from main pipe there may be a discharge of water into the nearest ravine or river.

Spot surface drainage is the easiest to implement, so you can easily lay it yourself. The greatest difficulty of this method lies in maintaining the correct slope of the water conduits so that the water itself flows through the pipes into the storm well.

The linear surface type in construction is more laborious.

Linear drainage is designed to divert streams of flood or storm water from slopes, from walls of buildings, from entrances to garages, if they are located at or below ground level. With this method of collection, water is collected and drained from the house and from the entire site using channels dug in the ground.

What size should the drainage channels be?

width - 50 cm;
depth - 60-70 cm;
channel wall bevel angle - 20º-30º.

The inner surface of the channels is concreted so that the water does not erode the soil. From above, the drainage channels are closed with removable decorative gratings that trap large debris, but freely pass water.

Drainage channels should be stretched from the house throughout the site with a slope so that the water drains into storm well or into a central storm sewer.

An open drainage method is easier to design and install if your site has a natural slope.

In the event that you do not want surface linear drainage to be visible on your site, you can use backfill drainage.

According to the principle of drainage, the filling type of drainage is very similar to the linear surface type, the difference is that the drainage channels through which water flows are covered with rubble, and grass turf is laid on top. This method also removes water well from the entire site, but at the same time the drainage system is not visible, which does not spoil appearance your site.

deep drainage

The deep drainage system is fundamentally different from the surface one, both in the way it is laid and in its purpose. If surface drainage was supposed to effectively divert water flows from the surface of the site during rains and floods, then deep drainage is designed to lower the groundwater level and remove excess soil water during prolonged rains and heavy floods.

According to the design, deep drainage is divided into:

Horizontal;
Vertical;
Combined.

Vertical drainage is a specially arranged drainage shafts, deepened on the territory of the site and equipped pumping stations. Vertical drainage is a complex engineering structure, therefore, on suburban areas practically never occurs.

Combined deep drainage is a combination of horizontal and vertical drainage systems. In some cases, only combined systems able to maintain proper water balance soils in difficult climatic and relief conditions.

Like vertical systems, combined is quite complicated structurally and has a high cost, so it is extremely rare.

Your attention!

Horizontal drainage systems are much easier and cheaper to install. When laying deep horizontal drainage, a drainage system plan is necessarily drawn up, due to its rather high complexity and a large number earthworks.

Deep drainage is structurally a set of buried drainage pipes that draw excess moisture from the soil and divert water into drainage wells.

Now, special pipes made of polyvinyl chloride (PVC) with a diameter of 63 and 110 mm are widely used as drainage pipes. These pipes are corrugated outer surface, smooth inner and perforation along the entire length.

To filter soil and sand particles from the outside, drainage pipes are wrapped in sheets of coconut fibers or geotextiles.

The laying of deep drainage is carried out in stages:

With the help of a geodetic level and a laser rangefinder, a thorough survey of the relief of the site is made. If you do not have the appropriate equipment and skills to work with it, then you can simply wait for the next rain and draw a diagram of the flow of water on the surface of the site. This diagram will help you plan your drainage trenches.
A network of trenches is dug into which pipes will then be laid. If after that you wait for the next rain, then, by tracing the movement of water in the trenches, you can check the correct laying. If the water does not collect in puddles anywhere in the trenches, then everything is done correctly and you can proceed to the next step.
Geotextile tapes 50-60 cm wide are laid along the entire length of the trenches.
Drainage pipes are laid on the fabric. At the intersections, they are connected using special tees or crosses.
The lower end of the main pipe is connected to a drainage well.
Pipes are covered with a layer of crushed stone with a fraction of 20-60 mm. Attention! It is strictly forbidden to use crushed limestone, as it is washed away with water over time, which leads to salinization of the soil.
Pipes and crushed stone are wrapped with overlapping geotextile tape to prevent clay and sand from getting inside.
The resulting fabric pipe is covered with crushed stone or coarse sand to a level of 20-30 cm below the ground.
Next, the trench is covered with a layer of soil typical for this area.

This completes the laying of deep drainage.

All of the above types of drainage systems, if properly designed and installed, as well as with timely maintenance, will last fifty or more years.

Your attention!

Drainage pumps

In addition to those discussed above stationary systems, requiring quite serious investments of money, time and effort, portable drainage pumps are often used for surface drainage of small areas of the area and pumping water from basements and cellars.

Device drainage pump easy enough. It is a compact pump with a wide working chamber and a stainless steel or plastic housing.

In this case, the water intake is carried out at the very bottom of the body, which makes it possible to almost completely remove water from flooded areas or basements. Thanks to the wide working chamber of the pump, it can easily cope with pumping water containing fine debris and sand.

The disadvantage of a drainage pump of this type is the locality of its application. With its help, it is possible to drain only one area at a time, while the rest will be flooded with incoming water.

In the process of construction planning country house be sure to remember that there are types of drainage necessary to collect and drain water from the site. Everyone hopes that the house will keep warm throughout years, but at one moment an excess of moisture, which is often facilitated by autumn bad weather or spring floods, can nullify all efforts. Damage will be done not only to the house itself in the form of destruction of the foundation, flooding of the basement, the appearance of fungus and rot, but excess moisture can also cause freezing and rotting of trees and bushes, disease of plantings.

That is why, in order to get rid of such a misfortune, it is necessary to equip immediately, when building a house. This will allow later, during bad weather or floods, not to create a landscape in a new way. personal plot, spending money on its arrangement and drainage.

Varieties of drainage

Consider what drainage is: these are various structures and pipes that allow you to lower the level of water, both groundwater and groundwater.

Often, perforated drainage tubes with holes in the walls are laid lower than the water level is located - ground ground-pressure. Pipes can be either asbestos-cement or ceramic, pottery and plastic or polymer - PVC and polyethylene. The diameter of the pipes can vary from 5 to 20 cm and even more. To prevent clogging of the walls and holes of the drainage pipes with soil particles, special shells are installed, which are made of filter materials.

There are two main types of drainage - a surface drainage system (open) and a deep drainage system (closed). Let's dwell on them in more detail:

Surface drainage plots are assembled from modular channels. This type of drainage is used to drain flood, melt and rain water from platforms and paths, the surface of the site, roofs of buildings and open terraces. This water is discharged into the storm sewer and outside the site. Open drainage of the site can be performed:

using point drainage or point elements;
organization of a linear drainage system or drainage line.

Another type of drainage deep- this is a system of channels and pipes through which water is discharged into a special well or collector, outside the site.

Pro tip:

The surface type of drainage is arranged to prevent the occurrence of waterlogging zones around buildings, therefore it is preferable to develop it in combination with deep drainage.

Surface drainage and drainage

Local collection of both rain and melt water is why point-type drainage is needed, and a drainage line is useful for collecting atmospheric precipitation from a large area. The best way is to combine these two systems. Let's dwell on them in more detail:

Drainage line. A linear drainage system is a system of deepened channels (drainage trays, gutters, gutters) and sand traps for them. A container that retains sand and small debris applied by water flows is called a sand trap. It protects storm sewer pipes and drainage systems from blockage. That is why it needs to be cleaned as it fills up. On the sand traps, as well as on the gutters, install removable gratings made of steel or cast iron.

Point drainage. The use of spot elements installed under drainage systems, designed to drain water from the roof, into the doorways - this is precisely what is meant by the local collection of water - rain and melt. Point drainage is complemented by linear drainage systems (gutters, sand traps) for the possibility of draining water from entrance areas, balconies and terrace surfaces.

deep drainage

Closed drainage or deep drainage is a system of channels (drains) located underground, lowering the level of groundwater and serving to drain water from the territory and from structures outside the site.

It is necessary when the site is located in a lowland, it is swampy or in other waterlogged places. In case of exploitation assumption ground floor it is also necessary to have a drainage device in the area, which in this case is wall drainage. According to experts, drainage is almost always necessary for middle lane Russia. Be sure to check the depth of the groundwater, even if the water does not squelch underfoot. After all, their close presence leads to decay and oppression of the root system of both shrubs and trees.

With a high location of a site with sandy soil that drains well, and the location of the groundwater level is lower than 1.5 m, deep drainage can be abandoned.

Deep drainage according to its design is divided into:

combined;
horizontal;
vertical.

Horizontal drainage has been described above, so consider the features of other types:

Vertical drainage - these are drainage shafts that are arranged in a special way, equipped with pumping stations and buried in the territory of the site. Such a site drainage system is a rather complex engineering structure. That is why vertical drainage is practically not found in suburban areas.

Deep combined drainage combines vertical and horizontal system. In some cases, it is he who can support in complex relief and climatic conditions required water balance. However, combined drainage, like vertical drainage, is structurally quite complex, has a high cost, and therefore is quite rare.

Drainage: his device

In order to arrange a drainage system, it is necessary to first dig trenches of the required depth, which should have a slight slope towards the drainage well and towards the natural watercourse, if possible.

Crushed stone or gravel and sand are poured at the bottom of the trenches.
Then perforated drainage pipes with holes for water passage are laid.
After that, it is covered with sand and gravel, and a layer of turf is laid.

Pro tip:

Usually lays pipes (drains) in several rows in the form of a herringbone. At the same time, the central drain collects water from the adjacent side parts, and then diverts it outside the site or into a drainage well.

A drainage well is arranged if there is not a sufficient slope to drain the water, or if there is nowhere to drain the water. In the well, if necessary, install a drainage pump.

Most often, the deep drainage of the site is laid parallel to the storm sewer, since the systems of underground and surface drainage solve different problems. Although some of the designers do not allow the combination of linear drainage with a deep drainage system, the rest of the designers consider this option to be quite acceptable.

Site drainage - what is it, in what cases should it be equipped, choice right system drainage depending on local conditions, the cost of arranging a drainage system.

In areas with a predominance of clay or marshy soils, it is advisable to equip the drainage system. It will help to avoid excessive waterlogging of the soil, increase productivity, save the foundation of the house from natural wetting and premature destruction.

The general scheme of the drainage of the local area

How to determine the need for a drainage system

by the most sure sign high humidity soil is the mass growth of plants, characteristic of swampy areas. These include weeping willow, sedge, reeds.

In addition to plants, puddles that remain after rain or spring snowmelt will be evidence of the close occurrence of groundwater. If they do not leave for a long time, then there is enough other moisture in the ground.

It does not always rain, so it is much easier to use a long-proven way to check the level of soil moisture. To do this, you need to dig a hole about half a meter deep at the highest point of the site. If during the day water collects at the bottom, then this area needs drainage.

Varieties of drainage systems

There are several types of systems that dehumidify a site with high level ground water. Before laying any of them, it is worth understanding the installation methods more carefully.

Types of surface drainage systems

Surface drainage of a site with a high level of groundwater on the adjacent and summer cottages conditionally divided into two groups:

Linear. It is equipped by digging trenches on the soil surface along the perimeter of the site and serves to remove moisture from rain and snow. Works flawlessly on flat surfaces without a sharp drop in relief. To do this, they dig trenches up to 30 cm deep and fill the walls with fine gravel. The disadvantage of such a system is that it looks rather unaesthetic and needs constant cleaning from leaves and small debris.

Elements of point and linear drainage

Spot. The simplest type of drainage, when water collectors are equipped in places of abundant water drainage - under roof drains, small ravines.

The installation of such systems does not require special knowledge, design calculations, and happens "by eye".

Deep drainage system

If the site is built on clay soil, with a sharp drop in relief or in an area with abundant groundwater, deep drainage is necessary. It is quite difficult to install. To develop a system project, you must contact a special bureau that provides services for geological exploration of the soil. Its specialists will accurately determine the level at which abundant aquifers pass and will help to competently cope with this problem.

Development of a drainage project

All deep systems are built on the same principle. The site drainage project is developed in such a way that all secondary moisture collection pipes are connected to the central line. It, in turn, ends in the main reservoir or is brought to the surface into a sewage ravine.

An example of the operation of deep drainage in the video:

In this case, the water intake should be located at the lowest point of the system. A very important point in the project should be the level and angle of the drainage pipes. In order to avoid silting or clogging, competent specialists will always offer the customer to mount manholes at each turn of the system. If necessary, or after several years, the wells are opened and the pipes are cleaned from debris under high pressure water pressure.

The water intake is always placed below the freezing level of the soil. Usually this mark varies between 1-1.5 m.

Additional Information! For the installation of a drainage system, perforated pipes are always selected. They absorb excess moisture from the soil with their surface and remove it from the site. A big mistake is that exactly the same pipes divert water from under the gutters from the roofs. On the contrary, abundant moisture from precipitation should be discharged into the central sewer in a separate way and not fall back into the ground through a perforated outlet. Otherwise, it will again fall into the ground and gradually begin to destroy the foundation of the structure.

Installation steps

After it was compiled detailed plan and all related factors are taken into account, you can proceed to the arrangement of drainage. Conventionally, it can be divided into the following stages:

Territory marking. Over the entire surface of the site, with the help of a peg and a rope, they mark out the future project.

Marking and laying pipes of the drainage system

Digging trenches. Ditches are dug to a depth of about 70 cm + 20 cm to compact the bottom. The width of the ditch varies within the width of the corrugation + 40 cm for freedom of occurrence.

Ditch sealing. The bottom of the trench is rammed and covered with a 10 cm layer of sand. A layer of fine gravel is poured on top.

Pipe laying. For deep drainage, it is best to use perforated plastic pipes. Recently, pipes wrapped with a special filter cloth have become popular. It is needed in order to prevent clogging of the system with sand. At corners, in places where manholes are installed, holes are made in the pipes for the convenience of flushing the line. During laying work, it is necessary to constantly monitor the level of inclination of pipes with a building level.

Backfilling of the filter layer. To prevent premature silting, the laid pipes are covered with a new layer of crushed stone. A decorative layer of soil is laid on top and it is well leveled.

Ready-made drainage with an intermediate well

Water well device. At the lowest point of the site, the main tank is installed, into which the collected water from the central line will accumulate. Near the well, if necessary, install a pump for pumping water.

The collected water can be used for watering flower beds and other plantings during the dry season.

artificial pond drainage

Some landscape designers propose to replace the main water intake well artificial reservoir, thus decorating the site. Main disadvantage this beautiful design solution- the risk of waterlogging of the man-made lake.

In this case, it is necessary to equip separately additional system pond drainage. It is better to lay out its bottom with a layer of fine stone and sand and compact it well. If the owner of the estate has expressed a desire to cover the surface of the reservoir with a film, it is necessary to equip an additional well (slucker). It is dug at a distance of about a meter from the pond and connected to it with a pipe along the surface. In case of excessive filling of the main reservoir excess moisture poured into an additional tank. Water from the cleaning well is pumped out if necessary.

Decorating a drainage system for a lake

Also, do not neglect simple and effective ways drainage of the territory. Trees or shrubs planted along the banks will naturally begin to evaporate excess water through the leaves.

Drainage features if the site is sloping

Drainage on a site with a slope is carried out according to standard scheme. The only difference will be that all auxiliary pipes mounted according to the "herringbone" system in relation to the central highway. AT without fail you need to monitor the correct slope of the pipes. The water well, in this case, is installed at the lowest point of the site.

Price

If you have certain knowledge and experience, you can do the drainage of the site with your own hands. But only a well-planned drain will work correctly, draining the site in a timely and efficient manner. Only experienced specialists can eliminate many errors, correctly calculate the angles of inclination and choose the project that is optimal in terms of material consumption. It is worth noting that drawing up a competent plan will help to avoid additional redevelopment in the future, which will significantly reduce the material costs of the owner of the plot.

It is best when the drainage is designed with the house

Price finished project drainage system with installation depends on the size of the territory, the desired number of manholes, the complexity of the terrain. The cost of a turnkey drainage system device starts from 1200 rubles per running meter. Deep - from 2700 rubles per linear meter

As practice shows, it is most expedient to equip deep and surface drainage at the same time. In this case, both systems will work simultaneously and with greater efficiency. Timely cleaning and proper care behind inspection and wells will significantly extend the life of the system and the integrity of the foundations of buildings.

Be sure to take into account that the soil in the place of the trenches will shrink significantly in the first season. Therefore, you should not immediately decorate it with capital plantations. It is better to survive at least one flood season and re-level the terrain with an additional layer of earth.

To significantly reduce installation costs, drainage pipes in the country can be replaced with a bunch of dry branches or a PET container design.

It is clear what site drainage is and how it works on the video:

As a result, with a high occurrence of groundwater on the site, the arrangement of the drainage system is not a luxury, but an urgent need. The cost of arrangement is low and in any case will pay for itself within a couple of seasons.
