Drainage area maximum length of pipes. We save money when choosing a drainage pipe

In the process of planning the construction of a residential building or country house, land owners often face the question of possible flooding of the territory groundwater or large amounts of precipitation.

In the spring, when the snow melts or in the fall, with constant rain, quite large puddles may appear at the dacha, which will interfere with the process of movement, and can also harm the plants. Usually all this is repeated from year to year, which can automatically lead to the complete destruction of the foundation.

With constant long-term water stagnation, the soil gradually becomes waterlogged, and no oxygen enters the soil at all. All this automatically leads to quite serious damage to all plantings.

Important! To prevent the dacha plot from gradually turning into a swamp due to precipitation, it is worthwhile to engage in high-quality drainage of the territory, that is, to arrange a drainage system.

A system of this type is a network of special pipes that interact with each other. They are usually located around or along a section of it and provide effective drainage of water strictly beyond its boundaries.

Drainage pipes are a system that is used to efficiently remove excess moisture from the territory, from the foundation part of the house, from farms and from the garden. Such structures are laid strictly with a certain slope towards a special water receiver. It can be of several types:

  • Ditch;
  • Common drainage pipe;
  • Drainage well.

Pipes intended for drainage differ from standard ones in their external characteristics. There are special holes on the top. Through them, the water that collects on the ground surface enters the interior of the structure, and then is completely removed outside the entire dacha area.

Modern pipes that are used in drainage installations can be of two main types - standard, with perforated holes, and they can also be completely wrapped with special materials that act as filtration.

At the moment, the following types of pipes are used in construction processes:

  • Perforated ceramic;
  • Asbestos-cement;
  • Made from high quality polymer.

The first two types are used quite infrequently, as they are characterized by heavy weight and certain disadvantages. Concerning polymer structures, then they are endowed with such positive qualities, How:

  1. Relatively light weight, which greatly simplifies installation processes and transportation of equipment.
  2. Simplicity in the installation process of the entire drainage system. Working with pipes of this type does not require special skills, and a minimum amount of time resources is spent. Thanks to this, drainage at the dacha can be done with your own hands.
  3. There is high-quality perforation that allows water to pass through, but not sand and small particles of soil; therefore, the drainage structure as a whole will not become clogged. In addition, pipes of this type have the ability to self-clean. If small debris penetrates, through a perfectly smooth surface, it is completely removed from the system.
  4. High performance and strength. The pipes have special stiffening ribs, which contributes to the most even distribution of the load.
  5. The general period of use is 40-50 years.
  6. Low cost of the entire system as a whole.
  7. There is relative immunity to destructive corrosion and resistance to aggressive environments.

Pouring process polymer pipes is carried out very rarely. The best option for such a system would be a pipe wrapped in high-quality geotextiles. In this design, it acts as a special filter that does not allow soil particles to pass through. If there is none, you will have to purchase a special one. Then you can forever forget about periodic flushing of the system.

Buyers are offered a wide variety of categories and standard sizes of polymer pipes. This provides an opportunity to build a drainage system that will have high performance indicators.

Modern pipes intended for arranging a drainage system are made from different materials. This can be regular PVC, polypropylene and polyethylene. Among them, PVC structures are in great demand, they can be:

  • One- and two-layer, having certain classes of ring strength parameters;
  • Flexible in structure, their length can reach 50 meters. They are produced in special reels. There are hard ones, the length of which ranges from 7 to 12 meters;
  • Having a filter membrane and bare. The material can be a special geofabric or high-quality coconut fiber.

Pipes made from polypropylene are not much inferior in quality to those made from high-quality PVC. They are also manufactured in corrugated and smooth forms, and the minimum diameter parameters are 50 mm.

Similar designs are produced in a wide range, and the basis is polyethylene, produced under low or fairly high pressure. Almost all types of pipes made of high-quality plastic are similar to each other in many qualities.

Pipes that are used in the drainage system or those intended for sewerage and city water supply are very different from each other. Here are the most basic differences between these designs:

  1. Purpose of pipes. Modern water supply and sewer pipes direct waste, that is, sewage and water, between certain elements of a particular engineering structure. As for modern drainage pipes, they effectively collect water accumulated in the ground.
  2. Differences consist in the materials from which pipes of all categories are made. This is a large and varied set in all respects - cast iron, polymers, steel and high-quality ceramics. Manufacturers make drainage pipes only from polymer bases. Companies have almost completely abandoned other materials.

  1. Important for sewer and water pipes sealing, that is, ideal moisture impermeability. Speaking about drainage structures, it can be noted that, on the contrary, their walls must be perforated in order to allow water to pass through very well.
  2. Pipes that are intended for the sewer system and for a standard water supply system do not differ at all from each other, therefore they can quite successfully interchange. Drainage systems have special additional structural elements that other structures do not have. Perforation is one such element.

The need for additional products also matters. For a drainage system, it is often necessary to purchase products such as or plastic.

The main features of drainage structures include partial or complete perforation. It has a direct impact on a large number of general drainage characteristics.

Full perforation is the production of holes that are located at a certain distance, approximately 60 degrees around the overall circumference. In other words, there are up to 6 holes in one section, and the standard diameter parameters are 1.3 mm. If the pipe is partially perforated, this means that there are 3 holes in its upper part and that’s it.

To protect all existing holes from fairly rapid clogging, many manufacturers perform perforation between the corrugations, that is, between the stiffeners.

Important! It is worth noting that such ribs help distribute the level of load as evenly as possible across the entire drainage structure. This has a significant impact on its durability.

The basic conditions for the use of a high-quality drainage design involve the use of different pipe models according to their characteristics, which are intended exclusively for drainage. Each of them solves one or another task as efficiently as possible.

It is for this reason that it is so important to determine exactly why all drainage work will be carried out on plot of land, as well as what devices you will need to take for this. For example, double layer pipe for water drainage, which is characterized by ideal strength and rigidity, ideal for laying in the ground to a decent depth.

Devices that have a special filter layer are initially intended for use in places where there is a likelihood of quite severe clogging or water with small parts of sand and gravel being poured into the drainage system. Pipes that have a sufficiently large diameter are used in areas where there is a need to drain large volumes of water.

Important! For drainage at a relatively shallow depth, the ideal option would be special corrugated single-layer pipes, with or without perforation, but with filtration material. The level of rigidity may be slightly lower than usual.

Buyers from Russia are now provided with quite varied selection quality pipes that are used for drainage. Their cost can vary, from 70 to 300 rubles. The price category directly depends on such parameters as:

  • Diameter;
  • Type of pipes;
  • Category of structures;
  • It matters where the product is purchased;
  • The volume of purchased products matters.

The arrangement of a high-quality drainage system must be planned in advance. You need to rely on General characteristics soil and soil, to maximum levels of underground sources.

Material expenses for such a design can be relatively small if everything is thought out in advance. A particular advantage is that in the future such an installation will help to effectively avoid various types of problems.

Drainage will protect the underground part of the house from inevitable destruction, protect plant roots from rotting, and get rid of stagnant puddles. Numerous advantages are somewhat offset by the price, the size of which is justified by a large amount of work. However, they can be fully or partially completed with your own hands, don’t you agree?

We will tell you how to install a drainage pipe with your own hands, and what system components still need to be installed. For those wishing to make their own drainage, we offer reliable information about the principles and rules of its construction. The information presented to you is based on regulatory requirements.

The article describes in detail the types of drainage systems. The organization technology is outlined, recommendations are given on the selection of pipes and related materials to ensure groundwater drainage. To help interested visitors, a selection of photos and video guides are included.

Drainage is an expensive system, even if you don’t have to pay for the services of specialists and the owner of the site is ready to do all the work himself. Therefore, you should figure out how much it is needed at all.

The need for a system cannot be determined by eye, because groundwater may lie close to the surface, which becomes a real problem only during floods or heavy rains.

Linear options become necessary if you need to drain areas around buildings, paths, entrances, or improve local area or remove excess moisture from the garden.

Such drains are shallow ditches into which water flows and then moves to special receiving tanks, storm drains, or to a discharge point off-site.

The choice and features of installation of elements of drainage systems depend on the expected load on the system: soil density, the amount of water that enters the drains. If the load is too great, you should choose structures made from the most durable materials

Point water collectors must also be accurately calculated and designed in advance. They serve to collect water locally, but are connected to a similar linear system of ditches or pipes.

Through the indicated drainage channels, the collected water is discharged in the same way into a collector well and then into a drainage ditch or pond. Therefore, work on installing systems with point water intakes is not much different from systems with linear options.

Open systems are very simple to implement and cheap, but they spoil the landscape with unaesthetic appearance. Another disadvantage is that the walls of the ditches have to be constantly adjusted, because they crumble under the influence of moisture, and the system ceases to perform its functions (water stagnates at the bottom of the trenches and does not move to the discharge point).


When planning drainage, you should decide on the type of system. You need to consider whether it will be open or closed. In the first case, ditches with slanted walls are dug to facilitate water drainage. The width of such a trench is usually 0.5 m, and it is dug to a depth of 0.7 m (+)

To solve the problem of crumbling ditch walls, you can use the crushed stone filling method: coarse material is placed on the bottom, and fine material is placed on top, after which the entire drainage pad is covered with turf.

This option allows you not to trim or strengthen the walls of the trenches, but it is suitable for areas with relatively low humidity, because The capacity of the ditch is greatly reduced.

The use of polymer and concrete trays in the construction of open drainage greatly facilitates and speeds up the work. In order to improve the landscape and protect systems from clogging, such open systems are covered with cast iron gratings.

For the arrangement, special perforated pipes are used - drains, laid to the depth of the foundation. They are placed in pre-formed ditches and covered with material with excellent filtering properties, gravel, small crushed stone or GPS.

To monitor the operation of the system and carry out periodic cleaning, install. They are located at each turn and every 20-25 m of the linear route of the drainage pipeline.

Drainage systems are laid not only to drain groundwater, but also to distribute it evenly, for example, in areas with a slope

Systems designed to drain the soil are installed close to the surface. Their depth does not exceed 40 cm

Normalizing moisture in the soil-vegetative layer does not require laying the system to a depth below the standard growth of the root system of cultivated plants

Drainage of the area to drain the soil-vegetative layer is arranged if loam or sandy loam is opened under the PRS. Rocks with low filtration properties do not allow water to pass through and contribute to long-term stagnation in the soil

The simplest option for drainage designed to drain the soil-vegetative layer is to simply replace the soil with rock with high filtration (gravel, crushed stone). In such cases, laying a drain is not necessary.

A drainage pipe is laid much lower if it is necessary to protect underground structures from groundwater

The drainage system to protect the foundation is installed 20-30 cm below the foundation laying depth. So it is necessary that the drain completely collects groundwater and prevents capillary suction

When installing a drainage system designed to protect the foundation from groundwater, it should be remembered that in addition to it, the foundation of the house needs reliable waterproofing

When determining how to properly lay a drainage pipe to protect plants from excess moisture, you can use average values. As a rule, the optimal depth is 0.6-1.5 m.

Moreover, for flower beds, lawns, beds, it does not exceed 0.9 m, and to protect the rhizomes of trees, you need to dig the deepest trenches, especially if the site is located on peat soils.

Types and parameters for choosing drainage pipes

Of all the materials for making pipes, polymers are the most popular. Their undeniable advantages are durability, resistance to chemicals and smooth internal walls to which dirt does not stick. Stormwater and groundwater flow into the pipeline and move freely to the reservoirs by gravity.

In the installation of underground drainage, plastic pipes with factory or home-made perforation are most often used. Less commonly used are ceramic or cast iron pipes, which are too heavy to install on your own.

Drainage system assembled from modern materials, can serve up to half a century. The main thing is to install it correctly, carry out technical inspections on time and not ignore the need for repairs.

Another advantage of polymers is their relatively low cost, because the finished drainage is inexpensive, practical and durable.


When choosing drainage pipes, it is better to give preference to two-layer products with stiffeners. Thanks to the even distribution of the load, the pipeline lasts longer and is more reliable. Plastic drainage pipes do not rust, do not rot and prevent the formation of sediment on the walls (+)

An excellent solution is a pipe covered in geotextile. The outer material filters water, trapping dirt. Thanks to this, the pipelines do not become silted.

An alternative to factory-made drainage pipes is conventional sewer pipes. You can easily make drainage components from them yourself. To do this, simply drill holes in the products and wrap them with geotextile fabric on top.

In addition to a perforated drainage pipe, to construct a closed system, you will need inspection and rotary drainage wells, a collector well, geotextiles and crushed stone or similar backfill material with high filtering properties

If a local drainage system is required, you can get by with pipes with a diameter of 100-200 mm, and if you need to remove moisture from a large area or there is too much water, it is better to choose products with a diameter of 300-400 mm. Optimal choice– a special drainage pipe with a filter shell.

Pipeline laying technology

When arranging drainage, the topography of the site is of fundamental importance. The system must be built so that there are no problems with the outflow of liquid into the ditches. If there are no results of geodetic research, you should draw up a diagram yourself, marking on it the places where rainwater drains.

When creating a diagram, you need to be careful, because mistakes will result in ineffective drainage. Based on the finished drawing, they outline how to lay and tilt the drainage pipe and where to install the catch basins. After checking the data, they mark the area and begin work.

To lay the drainage pipe, we develop a trench. Its depth is 30-50 cm below the base of the base

After mechanical development of the trench, we modify the bottom taking into account the slope towards the drainage of the collected groundwater system: a collector or absorption well

Cover the bottom of the trench with a 10 cm layer of quarry sand and tamp it down until a dense base is obtained for the drainage pipe.

We wrap the drainage pipe with geotextile. Ideally, it is better to lay the non-woven fabric in a trench, cover it with gravel, lay the drain on it, and then wrap it with material

We lay the drainage pipe, maintaining a slope along the compacted bottom, to the installation site of the absorption well

From two concrete rings we assemble an absorption well - a discharge point without a sealed bottom, instead of which a soil filter is installed in it, allowing water to pass into the underlying soil layers

Note! A large volume of melt and storm water can provoke a rise in groundwater levels. The occurrence of such a situation is extremely undesirable, since as a result the destructive effect on the foundation part of the building, as well as all elements of landscape design located on the site, increases.

  • increased soil moisture;
  • mold formation;
  • permafrost formation;
  • asbestos-cement;
  • ceramic;

  1. Large weight, requiring significant costs for transportation and installation, because the installation of such large products cannot be done without the use of specialized construction equipment.
  2. The slow process of installing a drainage system, which can only be carried out by professionals.
  3. Low performance. Drainage pipes are usually sold without perforation, so the holes are made manually. Because of this, during operation the pipeline becomes clogged faster, so frequent cleaning is required, and in some cases, complete replacement of elements.
  4. The construction of systems based on them is much more expensive than in the case of using plastic elements.

Installation of a water drainage system on a land plot using corrugated plastic pipes with perforation

Note! The table shows the average price of 200 mm drainage pipes from various materials. There are other diameter options, however, in products made of ceramics, asbestos cement and plastic, the standard dimensional parameters do not coincide. Therefore, for comparison, we took the diameter of the drainage pipe 200 mm, which is present in the range of all these products.

Drainage pipes for drainage of groundwater: introduction to the topic

The drainage pipe acts as the main building element, on the basis of which a drainage system is formed, designed to drain areas. This element is responsible for collecting and discharging underground, melt and rainwater outside the territory with their preliminary filtration.

The drainage system helps get rid of excess water in the area

Installing large-diameter drainage pipes allows you to cope with problems such as:

  • increased soil moisture;
  • mold formation;
  • flooding of the site, the foundation of a residential building and utility buildings, as well as cellars;
  • permafrost formation;
  • the appearance of puddles on paved surfaces;
  • ice formation on footpaths;
  • rotting of the roots of garden flowers, vegetable crops and other vegetation due to excess moisture in garden and summer cottage areas.

Features of drainage pipes with partial, complete or absent perforation

If we talk about general classification products for drainage systems, the range is represented by the following types of pipes (by type of material):

  • asbestos-cement;
  • ceramic;
  • plastic drainage pipes with and without perforation, as well as with its partial presence.

Drainage pipes come in a wide variety of types and sizes on the building materials market.

However, most construction companies have already abandoned the use of pipes made of ceramics or asbestos cement due to numerous disadvantages inherent in them:

Characteristics and laying of drainage pipes for drainage of groundwater

The drainage system is an important component of the improvement of the site; its basis is drainage pipes for draining groundwater. They can be made from different materials and have different diameters. They should be selected based on the characteristics of the site. This is what this article will be devoted to.

Why do you need a drainage system?

A drainage device for draining groundwater is required:

  • in the area adjacent to a large body of water;
  • in an area with marshy soil;
  • if observed on the ground high level humidity;
  • when the area receives large amounts of rainfall.

Drainage is necessary to drain the yard by removing excess water coming from various sources:

  • it could be precipitation;
  • melt moisture;
  • subsoil and irrigation water.

Due to excess water:

  1. Plants may die. Soil saturated with water does not allow oxygen to pass through. Nutrients needed by plants are washed out of it.
  2. Due to softening of the soil, the foundations of buildings may sag. Your home may also be damaged.
  3. Deformation of garden beds and garden paths occurs.

To prevent such problems, installation is carried out drainage systems for drainage of ground and other waters.

Types of drainage elements

Based on the material of manufacture, the drainage pipeline can be:

Pipes made from the first three materials are now rarely used, as they have many disadvantages:

  1. They weigh a lot. Therefore, their transportation and installation are quite expensive. The system must be installed using special equipment.
  2. Installation of ceramic, concrete and asbestos-cement pipelines is just as difficult. It is produced only by specialists.
  3. Such network products have low performance characteristics. Its elements in most cases are not equipped with holes. The pipes have to be perforated manually. As a result, they become clogged faster and need to be cleaned regularly.

Plastic products

Polymer products for groundwater drainage are superior in quality to analogues made from other materials. Its advantages:

  • long service life;
  • sufficient level of strength;
  • resistance to aggressive chemical environments;
  • low weight, thanks to which pipes are easy to lay, this process is carried out quickly;
  • due to the smoothness of the inner walls, deposits do not accumulate on them, so the pipeline does not become clogged for a long time;
  • the use of geotextiles during installation prevents siltation of the structure;
  • you can bury the system on your own; this does not require special skills or special equipment;
  • Plastic drainage is inexpensive.

Products are made from three types of polymer:

  • polyvinyl chloride (PVC);
  • polyethylene low pressure(PND);
  • polypropylene (PP).

The most popular drains are made of PVC. Polymer products can be:

  • one- and two-layer;
  • flexible (supplied in coils up to 50 meters long);
  • rigid (their length can be 6-12 meters);
  • perforated (fully or partially);
  • wrapped in filter material.

Besides plastic products for water drainage, it is divided into classes according to strength (ring stiffness). They are designated by the letters SN and numbers: 2, 4, 6, 8 and 16.

Diameters of drainage parts

Drainage structures have different diameters- from 50 millimeters to 425. This makes it possible to equip drainage networks of different capacities. For draining large volumes of water a large cross-section network is required -30-40 cm.

For household networks, in most cases, products with a passage of up to 20 cm are sufficient. Drains with a cross-section of 11 cm are most in demand in areas.

To calculate the diameter of the network, it is necessary to take into account the features of the site:

  1. Moisture level and type of soil.
  2. Filtration coefficient.
  3. The depth of soil freezing.
  4. Water inflow dimensions, etc.

When it is necessary to drain a courtyard with an area of ​​up to 400 m², pipes with a cross-section of 11 cm are sufficient. Products of the same size are also installed to drain the foundation of a building. The radius of groundwater drainage with a pipe with a cross-section of 11 cm is 5 meters.

The drainage system can be wrapped in geotextile. It will filter garbage. The width of the trench should be 0.4 m larger than the cross-section of the network elements.

For large areas, large diameter drainage pipes for ditches (20 cm) are used. Their depth is approximately 8 m, taking into account the pressure load from the soil.

LDP (large diameter pipes) with a diameter of 31.5 and 42.5 cm are mine and are used in most cases to equip a drainage well. Such products can withstand maximum pressure loads.

Which drain to choose based on characteristics

Flexible single-layer products equipped with perforations, can be used at a depth of no more than 3 meters. The category of products based on ring stiffness can also indicate the desired depth of installation. For example, SN-2 products can be buried no more than 2 meters, and SN-4 - 3 meters.

Double layer drainage smooth inner walls. Its outer layer is corrugated. In most cases, the strength of such products is SN-6. When laying the drainage network, two-layer elements no more than 4 meters long are used. They can be wrapped in geotextile or coconut fibers as a filter layer.

Flexible single-layer perforated and corrugated products belong to strength class SN-8. They can be equipped with a textile filter or supplied without it. They can be laid to a depth of up to 10 meters. Double-layer drains of this type are buried no more than 8 meters. They do not come with a filter.

Elements for storm drainage

In a storm drainage system, liquid is drained by gravity, i.e. no external compression action is applied. Therefore, there are no special pressure requirements for such a sewer network. Only one strength parameter is important here - the storm drainage, when buried, must withstand the weight of the backfill.

There are also minimal requirements for the thermal resistance of products. Operation of the storm drain does not occur when high temperatures. The only condition is that the drains should not lose strength in winter, at negative temperatures. In a properly designed and installed storm drainage system, moisture will not stagnate. Therefore, there will be no risk of network freezing.

When the underground method of laying pipes is used, they are exposed to aggressive chemicals that are dissolved in water or located in the ground. Based on this, the most important condition for choosing drainage elements is their inertness to such compositions and resistance to corrosion.

The most important quality of a storm network is its capacity. The required drain cross-section is determined at the system planning stage. Most often, elements with a diameter of at least 11 cm are used for drainage.

Another condition for effective functioning storm sewer- the lowest possible level of hydraulic resistance inside the pipes. The walls of the products should be as smooth as possible. Then almost no dirt and debris will settle on them.

The length of storm drains can vary. However, it is best to choose elements with the maximum length. This way you will reduce the number of interfaces in the system - this will increase its efficiency and reduce the cost of installation.

Choice drainage products for groundwater drainage

The foundation of buildings can be washed away by subsoil moisture at depths of up to 2 meters. At the same time, substances that contribute to the destruction of building materials may be dissolved in groundwater.

Waterproofing in in this case can't help much. The best option is to bury the drainage pipeline. When designing it, it is necessary to take into account the type of soil and its level of moisture.

Increased liquid content in the soil leads to freezing, rotting, diseases of plant crops, and waterlogging of the farmstead. To prevent this from happening, for drainage it is necessary to choose corrugated products made from low-density polyethylene.

Optimal types of pipes for different types soils are presented in the table:

Drainage pipe manufacturers

Now more and more factories are opening that produce pipes, including for drainage systems. However, most often they use products that are produced by trusted and well-known manufacturers. Among Russian companies This:

Among foreign manufacturers The products of the companies are in demand:

In fact, the technology for making drains is the same everywhere. Therefore, all factory products have approximately the same quality. The only difference is the cost of the products.

Do-it-yourself drainage pipe installation

Before laying the drainage structure, it is necessary to calculate it and select the optimal type of pipes. The project will require a site plan. As well as geodetic data, they can be obtained from the regional land use department:

  1. Seasonal depth of subsoil water.
  2. Features and structure of the soil.
  3. The average annual volume of precipitation and flood moisture falling on the site.

Knowing these parameters, professionals will carry out the necessary calculations and determine at what depth to bury drainage pipes and their diameter.

The arrangement of a network for drainage of liquid is carried out as follows:


The structure is discharged into a ditch, a nearby reservoir or storm drain. At the end of the outlet pipe is put check valve . When it is impossible to arrange such an exit, a storage well is installed. When it is completely filled with water, it is pumped out using a pump.

When arranging drainage to drain liquid on a site, do not forget that the entrance to it must also be equipped with a pipe. There, it will be necessary to bury a product with maximum annular rigidity in the ditch.

When installing a drainage system, you should avoid making mistakes that could lead to disruption of its operation. The most common of them:

  1. Insufficient drainage depth. This may lead to a disruption in the water balance of the area.
  2. The use of liquid drainage products that are not suitable for the site conditions. This leads to a rapid shutdown of the network.
  3. Incorrectly selected network slope angle. This will lead to problems with groundwater drainage on the site.

Cleaning the drainage system

When maintaining a structure for draining groundwater, it is necessary to periodically check whether it is clogged or damaged. When problems arise, they are promptly resolved.

You should also regularly check the level of subsoil water in the courtyard of the site. This way you will be aware of how effectively the drainage copes with removing excess fluid. Thanks to timely preventive and repair measures, you will be able to not only extend the life of the drainage, but also prevent the risk of accidents.

The drainage structure should be washed regularly. This way you will stop it from clogging or get rid of it if it has already happened. For maximum washing efficiency, it is necessary to choose the method that will be most suitable in each individual case. There are three such methods in total.

The first one uses an ordinary watering hose. It is inserted into the drainage pipeline and supplies water jets under pressure. They wash away deposits and blockages from the inner walls of the network.

The garden hose is flexible and the water pressure from the household tap is not too strong. Therefore, this method is used to clear minor blockages in short sections of the drainage network.

The second washing method uses a compressor. It is more effective than a regular hose. It supplies mixed air and moisture inside the drainage structure. They effectively and quickly clean the network from the inside. When using a compressor, it is possible to regulate the pressure. Therefore, this method can be used in most cases of blockage.

The third method is hydrodynamic. It uses a compressor pump and a hose with special nozzles. With their help, water is supplied into the drains under strong pressure. Its jets cut deposits from the pipe walls. The system is then flushed under high pressure to remove any remaining dirt. This cleansing method is the most effective.

By choosing any of the three methods above, you will need to gain access to both sides of the drainage branch. Jets of water will flow from one end, and its removal will be ensured from the other.

Conclusion

Installing a drainage pipe in a ditch yourself is quite feasible. In this case, professionals should be entrusted with the necessary calculations and the creation of a drainage system design. Direct installation of the pipeline is not that difficult. The main thing is to strictly follow the installation rules, maintain the required slope of the network, reliably connect its elements and equip inspection wells.

Drainage pipes for drainage of groundwater - laying and installation of a drainage system in a ditch, at what depth to bury


Let's look at the characteristics and methods of laying drainage pipes for draining groundwater, find out how to choose a pipe for the system and what diameter, at what depth to bury

Drainage pipes for drainage of groundwater

The depth of groundwater is determined by the geological structure of the area and can vary depending on the amount of precipitation and spring snow melting. An increase in the groundwater level in a personal plot can lead to the following problems:

  • flooding of building foundations, basements and cellars;
  • formation of frozen layers and increase in soil heaving;
  • high humidity and waterlogging;
  • the appearance of non-drying puddles and ice on footpaths;
  • rotting of tree and plant roots.

A solution to the issue of draining excess water from the upper layers of the soil can be drainage pipes for draining groundwater, combined into a single system. Thanks to this, the level of groundwater can be reduced to normal limits by discharging it into a reservoir or lowland, providing preliminary filtration, which prevents soil erosion.

The operating principle of water drainage systems is very simple. Perforated pipes are laid along the building or around its perimeter at the required depth, into which moisture enters through the holes and is transported to intermediate, rotary and collection wells. After this, the water is discharged through pipelines to the nearest reservoir, lowland or any other reservoir.

Types and characteristics of pipes used

Based on the type of material, pipes for groundwater drainage are divided into:

In turn, polymer pipelines can be made of vinyl plastic, polypropylene, polyvinyl chloride or polyethylene. The inner surface of plastic pipes is smooth, and the outer casing is corrugated to increase the strength of the material.

Asbestos-cement and ceramic materials

Today, most construction companies and private developers have abandoned the use of ceramic and asbestos-cement pipes in drains. As the practice of construction and further operation has shown, these materials, in comparison with plastic, have a number of significant disadvantages, which include:

  • high cost and heavy weight, increasing transportation costs;
  • the need to use special equipment for laying heavy pipes;
  • complex installation of connections, requiring special skills to emboss joints;
  • lack of perforation, which has to be done manually yourself;
  • increased roughness of the inner surface, which contributes to accelerated siltation of pipelines.

These shortcomings contribute to a justifiable increase in demand for pipes made of polymer materials specifically designed for drainage systems.

Polymer materials

Plastic pipes for groundwater drainage can be made from various raw materials. The most popular category, which has the best price-quality ratio, includes products made from polyvinyl chloride. Polyethylene, polypropylene and vinyl plastic are more expensive, but the quality remains at the same level.

By design, polymer pipes can be:

  • single-layer or two-layer;
  • various strength classes, from SN2 to SN16;
  • with or without a surface filter layer of geotextile;
  • rolled into coils up to 50 m long or in straight sections up to 12 meters.

Wherein polymer materials They are characterized by a long service life, high strength and resistance to moisture. Light weight and availability rubber seals significantly simplify the installation of pipelines, which you can do yourself. The smooth internal surface and the presence of a filter coating prevent silting and clogging of the system.

Polypropylene pipes.

Pipes made of porous materials

Such drains are made of plastic concrete or expanded clay glass. These pipes do not have perforations, and water seeps into them through pores in the walls. This structure is convenient in that it does not require an additional filter layer or surface sprinkling with crushed stone. However, the reduced strength of porous drains and their high cost limit their widespread use.

Selection of pipes depending on soil type

When choosing the type of perforated pipes, it is necessary to take into account the geological structure of the soil on the site, since this factor significantly affects the saturation of the soil with moisture and the possibility of moisture passing into the lower layers. Depending on the geology of the soil, it is recommended to use:

  • on sandy soils - pipes with a filter layer of fabric and the presence of a surrounding crushed stone bedding;
  • on clay soils - drains with or without a filter, surface and surrounding crushed stone bedding;
  • on loams - pipe material with a filter without bedding;
  • on chernozems - pipes without a filter with crushed stone around the line;
  • in rocky soils - perforated pipes without a fabric filter and crushed stone.

That's why final decision the choice of the type of drainage pipelines can be made on the basis of geophysical survey data on the site with determination of the real groundwater level and geological structure soils in sections.

Depth of drains and distances between lines

Single-layer drainage pipes for draining groundwater can be laid to a depth of no more than two meters. Further determination of the maximum burial depth depends on the strength indicator. SN4 materials can be installed to a depth of up to 3 meters, and SN6 - up to 4 m.

The distance between drains depends on the depth and type of soil.

If the pipeline is laid under a roadway, a car parking lot or at great depth, the strength index must be at least SN10. Double-layer corrugated materials allow maximum depth of up to 10 meters. In this case, the presence of a filter coating is not necessary.

When choosing diameters, it should be taken into account that one drain with a diameter of 110 mm is capable of effectively draining groundwater from a strip 10-15 meters wide at a depth of 1.8-2.0 m and from a strip 5-7 m at a depth of 0.5 meters. That is, the greater the depth of the pipes, the larger the area they can serve.

In addition, the type of soil and the average water level should be taken into account. So on clay soils, the distance between adjacent drainage lines should not exceed 10 meters at any depth. In the case of loams, the maximum distance is 20 meters, and on sands - no more than 40 meters.

Experts determine the optimal depth for laying pipelines within 1.5-2.0 meters. This will increase the distance between drains and reduce the cost of installing the system.

Pipeline diameters and perforation methods

The enterprises produce plastic pipes for the installation of drains with a diameter of 63 to 1200 mm. To install drainage systems in private construction, pipes up to 300 mm are used. Perforated sizes 63-110 mm are laid in places where water is collected, and 110-300 mm without perforation are used to transport collected moisture outside the building site. Pipelines with a diameter of more than 300 mm are used in industrial and civil construction of large facilities and agricultural land reclamation.

The diameter of the drainage area determines the number of perforations, and therefore the amount of moisture collected from the soil. Therefore, in private building areas, in most cases it is recommended to use pipes with a diameter of 110 mm with a laying depth at the starting point of 1.0-1.5 meters.

The use of a 63 mm drain may be ineffective, and a 160 mm drain will lead to an overall increase in the cost of the system due to an increase in the cost of purchasing materials.

Pipe perforation can be performed by the manufacturer in the factory or independently, on products with a solid surface. Pipe manufacturers use 4 methods for locating holes:

  • partial, with two holes at an angle of 120˚ in the upper part, with the length of the holes being a quarter of the diameter;
  • with two holes at the bottom;
  • with four holes in the upper half with a 40˚ angle between them;
  • with six holes along the entire diameter of the pipe.

If there is no perforation, you can cut it yourself using a grinder or other tool. In corrugated products, holes are made along the lower edge of the corrugation. In this case, all edges and the inner surface must be thoroughly cleaned of burrs and fallen plastic particles.

To provide filtration and protection against the penetration of polluting particles, pipes sold may have an additional outer coating of geotextile. If there is no filter layer, then you can also wrap the pipe with such material yourself.

Connection methods

The connection options used depend on the type of pipes being laid and the material from which they are made. Ceramic and asbestos-cement pipelines are connected using socket and coupling elements with the joints sealed with heel or semi-dry cement, which are driven into the joint using caulking. This method requires special skills and is performed only at a professional level.

Plastic pipes and other system elements are connected through a sliding socket with a rubber ring seal or using end thermal welding technology. In the first case, the assembly is quite simple and can be done independently.

During installation, the rubber seal and the end of the pipe must be lubricated with a special mounting lubricant. This makes the job much easier.

End welding requires the presence of a special welding machine and the ability to operate this equipment. Therefore, this technology is used only by construction and installation companies.

Drainage pipe manufacturers

Materials for the construction of groundwater drainage systems are manufactured at many enterprises in Russia and other countries. Among the most famous and popular Russian companies producing polymer pipes, it should be noted:

The products of these manufacturers meet international standards and are quite affordable for most developers.

In addition, on the building materials market you can purchase products from such foreign companies as:

The manufacturing technology and product quality of all manufacturers are approximately the same. But you have to pay more for pipes from foreign companies, taking into account the costs of customs duties, transportation and a well-promoted brand. But the final decision on choosing a manufacturer must be made by the developer, based on his financial capabilities.

Installation of a drainage system on the site

Drainage installation on the site must be completed before or simultaneously with the construction of the foundation of the house. This will reduce the volume earthworks and position pipelines for maximum efficiency. To increase the flow of water to the drain around it, it is necessary to place an additional drainage layer of crushed stone, gravel or river pebbles.

The work should include the following stages:

Drawing up a diagram for laying pipelines on the site, selecting materials and marking the area. If you do not have experience in organizing and carrying out such work, contact a specialist for help in developing a diagram! It is quite possible that qualified assistance will allow you to avoid mistakes and unnecessary additional costs.

Excavation work, during which trenches and holes are dug for the installation of rotary and prefabricated wells. The bottom of the trenches should have a slope of 1-2% towards the drainage of collected water. The width of the trench is equal to the diameter of the pipe with the addition of 0.4-0.5 meters. The depth is determined by the level of groundwater.

Angle of inclination of the drainage system.

Attention! When installing slopes, you should not make them more than 5%, as this can lead to a significant deepening of the pipeline at the finishing point, as well as to too high a speed of water movement.

  1. After excavation, the bottom of the trenches should be compacted and the leveling material should be filled sand cushion 5-10 cm thick.
  2. Install drainage wells provided for in the scheme, which should be located in all places where lines turn, where flows converge and where wastewater is collected. In addition, on straight lines the distance between wells should not exceed 30 meters to maintain the possibility of cleaning them during operation.
  3. Lay geotextile fabric in the trench so that its edges extend onto the walls. After this, you should fill in a layer of crushed stone, gravel or pebbles 15-20 cm thick.
  4. Level the surface of the bulk material, compact and lay the pipes. The assembly of the pipeline begins with perforated drainage sections and is carried out in the direction of the place where water is collected or discharged into the reservoir.
  5. Carry out a control check that the pipes are laid correctly. To do this, flood the pipelines in all directions with water, pouring it into the wells.
  6. Completely fill the pipeline with crushed stone so that the surface of the stone exceeds the pipe by 20 cm. Tamping is not performed after this so as not to damage the integrity of the pipe.

Laying in a trench.

Important! Pipes that do not have perforations are not covered with crushed stone, since they are lines that only transport water. It is enough to fill it with sand 8-10 cm thick.

Wrap the edges of the geotextile onto the surface of the bulk material. This way you will have a completely fabric-wrapped stone shell around the drain.

Finally, backfill the trenches and level the area.

It should be understood that any drainage system requires periodic monitoring of its technical condition. This is ensured by inspecting wells for siltation and capacity. As soon as necessary, it is necessary to flush the pipelines from silt deposits.

Drainage pipes for drainage of groundwater: types, installation instructions


A solution to the issue of draining excess water from the upper layers of the soil can be drainage pipes for draining groundwater, combined into a single system.

Or houses. In any metropolis there must be invisible systems for drainage of fallen and groundwater; owners of a private estate have to decide on the issue of dealing with storm, melt and groundwater on their own. It will help with this modern look pipes for drainage - perforated drainage pipe.

A drainage system is a complex system of pipes (drains) and wells, sometimes pumps, to collect and remove high groundwater and sediment from houses and wetlands.

The question of the need for drainage on a site is not so simple. Drainage of excess water is necessary in the following cases:

  • if water regularly gets into the basement under the house or the ground floor used as a gym, library, cinema hall, boiler room;
  • if the walls of the house crack and sag;
  • if the water in the well is above the level of the foundation (and especially if it is close to the surface);
  • when the area becomes swamped, if after a rainfall the water does not absorb on the ground for a long time and there are puddles;
  • in clayey areas;
  • if the site is on a slope or in a lowland.

Drainage can be superficial or deep. Deep drainage is carried out around the house to drain groundwater and to protect the foundation of the building and the ground floor, by design it is always made closed. Water is removed from the site using surface drainage (by design it can be open or closed). Storm drainage – .

In our article we consider the most progressive type of material for closed drainage - perforated pipes.

Drainage pipe installation

Installing a closed deep drainage is not the most difficult job; it can be done on your own. The work itself is quite banal: dig a trench, fill it with crushed stone and sand, install pipes, fill the trench. The difficulty in installing drainage is the choice of diameter, slope and other design intricacies.

It is advisable to install water drainage from the foundation simultaneously with the construction of the house (and in the case of long-term construction, with laying the foundation).

Principle of operation

The principle of operation of drains is simple - water seeps in, flows in the direction of the slope, collects in water intakes or enters the city sewer.

Kinds

Modern perforated pipes are made of plastic - HDPE (low-density polyethylene) and PVC (polyvinyl chloride). There are rigid and well-bending (flexible) varieties. Rigid ones are sold in measured lengths - 6 and 12 m each. Flexible ones - in coils up to 50 m long.


Drains can be single-layer or double-layer. , corrugated outer layer and smooth inner layer.

To indicate the strength of perforated drains, the coefficient of ring stiffness of the product is used: SN2, SN4, SN6, SN8, SN16 (in order of increasing rigidity).

There is a division of products according to the number and location of holes: fully perforated ones have six rows of holes located along the entire circumference of the pipe; partially cut - only three rows.

As a rule, corrugated pipes are used to drain groundwater.

Ceramic and steel pipes with perforations are also used for drains, but due to their shortcomings they have practically ceased to be used. They stopped using them because of their limited service life (up to 30 years), weight, fragility, cost, and complexity of installation. Concrete structures have large diameters and are used only in municipal systems. Products without perforation are also no longer used.

The most modern products Available with a geotextile filter.

Advantages and disadvantages

Ceramics

Steel as a material has a fairly significant cost; such pipes are susceptible to corrosion and “overgrowing” with a coating of insoluble calcium and magnesium salts. But the strength of metal exceeds any other type of pipe and sometimes you simply cannot do without it. The service life of products with anti-corrosion coatings reaches 40 years. There are smooth and corrugated.

Ceramics are a fragile, heavy material, it is difficult to install; there are no fittings for them to connect to modern manholes, for connection, or rotation.

The most current and popular type of drainage pipes for private estates is polymer.


Advantages of plastic products:

  • low cost;
  • ease of installation;
  • no corrosion:
  • plastic;
  • Availability of a huge range of pipes and components (corrugated and smooth, double-layer and single-layer, with and without filter material).
  • double-layer drains have very smooth internal walls - this increases the speed of water flow and the volume of water discharged.

Disadvantages: in some cases - if there is a danger of landslides, earthquakes, severe ground subsidence - the strength of the plastic may not be sufficient and a metal drainage system will have to be installed.

Material

It is better to buy certified material in construction hypermarkets. approximate price materials are much less than the cost of work, and the quality largely depends on the material. For the same reason, you should not use used materials.


If it is necessary to deepen the drainage system by more than two meters, we recommend choosing two-layer pipes - they have greater rigidity; the smooth internal surface allows them to be laid with a smaller slope and not to deepen the trench “to the center of the Earth,” which is important when the distance to the collector well is large.

Diameter

When choosing the diameter of the drains, it is necessary to take into account all the factors affecting the amount of groundwater: the amount of precipitation, its distribution by season and month; height of groundwater relative to the bottom of the foundation, dimensions of the house; slope of the ground surface (slope, lowland, hill), seasonality of groundwater rise.

If groundwater rises above the level of the bottom of the foundation 1-2 times a year (mainly when snow melts), you can choose ring drainage around the house:

  • for a house area of ​​up to 70 m² - diameter 100 mm;
  • 100-120 m² - 150 mm;
  • 120-150 m² - a diameter of 150-200 mm is desirable.

If the house is located in a swamp or the groundwater level is higher than the base of the foundation, the house is located on a steep slope or in a ravine, the house has a built-up area of ​​200 m² or more - do not experiment with your own home, contact specialists and make a project - it will turn out more reliable and cheaper than remodel the sewer system that cannot cope with the volume of discharged water, repair the basement and seal cracks in the walls.

Soil type

Clay and loamy soils retain water. In chernozems and sandy loam soils, water usually drains quickly and without problems. All other things being equal, when installing drainage pipes in loam and clay, you should choose a larger pipe diameter.

Basic rules for laying perforated drainage pipes

The device for draining water from the foundation is not as simple as it seems at first glance. Here we will describe all the features of the drain installation process.


Wall deep drainage around the house is located below the depth of soil freezing, below the foundation and in any case, no higher than 1.2 m from the ground level. It is located at a distance from the walls of at least 1.5 m, from the blind area - 0. -1.2 m. Ditches are dug at least three pipe diameters wide. To the required calculated depth, it is necessary to add 0.3 m - the thickness of the bedding made of crushed stone and sand (crushed stone carries out primary filtration of groundwater).

The first step is to pour bedding onto the bottom of the ditch. First, wide and narrow geotextile tapes are laid to wrap crushed stone and sand.

Then a layer of sand 100-150 mm thick is poured, compacted, and wrapped in textiles. Fill the crushed stone with a filter layer equal to the diameter of the drain and level it with a piece of board nailed to a stick. Crushed stone fraction – 16-32 mm. Before backfilling, wash the crushed stone with high-pressure water from a hose for 10-15 minutes. It is convenient to do this by pouring crushed stone into small piles. Then it is either used or packaged in bags and stored for no more than a week.

You can't dry it!

Starting from the collector well, perforated pipes are laid. They fill it with washed crushed stone to the height of one pipe diameter and wrap it with a large piece of geotextile. Cover with fine unwashed crushed stone of fraction 8-40 mm in a layer of 100-200 mm. Covered with earth.


The slope of the drainage system is determined by SNIP 2.04.03 and varies within 2-10 mm per linear meter. The slope should increase slightly towards the collector well. With a uniform slope, the system silts up faster.

Wells must be installed at every second turn of the pipes and at their connections. Pipeline outlets must be at least 250 mm above the bottom of the well.

No matter how good the filters are, the drainage system is still clogged with organic residues (“silting”), so periodic cleaning of the system is required – once every 3-4 years.

How to clear a clogged drain pipe

There are two main ways to clean drains: mechanical and hydrodynamic. For mechanical method They use special pneumatic installations with a device for grinding deposits.

This is a communications system that is laid below the soil surface and helps drain groundwater into a special well or ditch outside the site. Thanks to this solution, it is possible to avoid flooding of basements and cellars, rotting of plant roots and the regular formation of puddles.

First of all, pipes for site drainage are divided into groups, the products in each of which differ in the type of material:

  • asbestos-cement;
  • ceramic drainage pipes with perforations along the entire length of the products;
  • polymer.

But for some time now the first two types have practically gone out of use, because The popularity of plastic analogues is growing rapidly. The disadvantages of asbestos-cement and ceramic products quite eloquently explain this state of affairs:

  1. Excessively heavy weight, which greatly complicates not only the transportation of the material, but also the process of installing the drainage pipe. To do this, you usually have to use special equipment.
  2. Difficult pipe laying technology with the need for perforation. As a result, it is extremely difficult to carry out installation yourself.
  3. Relatively short service life (on average 20-30 years).

Polymer communications are available in two versions: uncoated perforated pipes for drainage and wrapped in filter material. If a filter is enabled, more high degree efficiency of the system, since the special material retains large and small particles of contaminants and sand, which, in turn, significantly reduces the likelihood of rapid siltation of the pipeline from the inside.

Polymer communications are also classified based on differences in the source material. It could be polypropylene, polyethylene, polyvinyl chloride (PVC) products. Polyethylene versions are found in two variations: high and low pressure (LDPE and HDPE). In terms of popularity, polypropylene products are somewhat inferior, but only slightly.

Polymer pipes for site drainage are distinguished according to design features:

  • single-layer versions;
  • two-layer.

Each of these options is characterized by a certain level of hoop strength. There are varieties that differ in degree of rigidity:

  • flexible corrugated pipe for drainage (length varies between 40-50 m; for ease of transportation, products are produced in reels);
  • hard communications (produced in sections of 6 and 12 m).

Plastic versions of drainage pipes for drainage of groundwater have a number of advantages:

  1. High strength characteristics. This applies to a greater extent to the two-layer version. The increased degree of endurance is due to the presence of stiffeners, which contribute to the uniform distribution of the load exerted on the pipeline.
  2. Very long service life without signs of external deformation and loss of the product’s basic properties (50-60 years).
  3. A high degree of resistance to aggressive substances, which are often found in large quantities in the soil, as well as resistance to corrosion.
  4. Light weight, which allows you to independently cope with the task of installing the pipeline.
  5. The presence of protective filter material increases the efficiency of such communications.
  6. Low costs for arranging a drainage system. This is explained by the absence of the need to invite specialists to install pipes, and in addition, the relatively low cost of such products is noted. Especially if you compare the duration of operation with analogues. Thus, in the case of asbestos-cement or ceramic communications, the pipeline should be replaced three times more often than plastic products.

In addition to all that has been said, one more positive point can be added - a wide range of, which will allow you to select pipes for the site’s drainage system in accordance with the requirements and operating conditions.

Selection principle

There are basic criteria on the basis of which communications of this kind are selected:

  1. The type of drainage system (open and closed), which determines the preferred type of product in each specific case. In this case, the presence of holes plays a major role. Yes, for closed systems the best option is a perforated pipe. The purpose of drainage in this case is to remove groundwater from the site. Open systems are designed to collect and transport atmospheric precipitation and melt water to a water intake.
  2. The dimensions of the product are determined, first of all, by the amount of liquid that will be drained. For simple tasks, communications with a diameter ranging from 100 to 140 mm are usually purchased; for transporting large volumes of groundwater, pipes up to 300 mm in diameter are used. For country houses, drainage pipe 110 in a geotextile filter is often used.
  3. The level of load exerted on the product (determined by the depth of installation) necessitates the use of one- or two-layer designs. Recommended hardness class: from SN2 to SN16.
  4. Material. Corrugated pipes made of PVC for drainage of garden plots are the most popular today. Therefore, if the user wants to make the installation task easier, save money and end up with a long-life system with high strength characteristics of the pipeline, then this option will be the best solution.

In addition to all that has been said, operating conditions should also be taken into account. In the case of rocky soil, geotextiles are not used. In all other situations, there are no restrictions on the installation of filter material and a corrugated perforated drainage pipe can be used during installation.

Installation instructions

Before starting work, a pipeline layout diagram is drawn up. The herringbone option is usually used. The distance between communications is influenced by the type of soil: for sandstones, the distance of the “branches” of the drainage system from each other corresponds to a value within 45-50 m, in the case of preferably clay soil, the distance reaches 10 m, for loamy soil – 20 m.


When you plan to lay pipes for drainage and storm sewerage, you must adhere to the following instructions:

  1. A trench up to 1.5 m deep is dug along the walls of the house, which is mainly determined by the level of groundwater. The width of the ditch should exceed the size of communications by almost half a meter. During work, we must not forget about the slope of the drainage pipe for unimpeded outflow of water.
  2. A sand and crushed stone cushion 10-20 cm thick is laid at the bottom of the trench.
  3. Geotextiles are laid, on top of which crushed stone is again poured.
  4. Pipe laying is carried out taking into account the slope at the rate of 2-3 cm per meter.
  5. Inspection wells are located at joints and turns.
  6. The communications are covered with gravel, on top of which the edges of the geotextile previously laid on the bottom are laid.

At the final stage, the entire structure is covered with sand and soil. The result is a protected drainage system. And taking into account the use of polymer communications, the need for frequent replacement of pipes is reduced. Accordingly, the resulting structure can remain intact for a long period.

Thus, if as suitable option plastic pipes for drainage are being considered, the price of such products is not that high (on average from 60 to 200 rubles/m.p.), and the quality of the system will be excellent. This is determined by the high strength characteristics of communications, long service life, and resistance to aggressive environments. A wide range of polymer pipes also plays an important role, which will allow you to choose the option that is most suitable in terms of diameter, type and type of material.
