Storm drainage or storm drainage is a mandatory element for removing excess moisture from the site. Even if the soil is rich in sand, but water is retained, it is possible that the ground aquifer is close to the surface, which means that drainage work will have to be done. The system consists of a pipeline, the required number of drainage wells, which can carry different functional loads. It is important to understand the design of a drainage well in order to buy and install it yourself.

If we consider the structure of a drainage well from top to bottom, it consists of the following elements:

• lid;
• neck;
• mine;
• bottom part for collecting sediments.

Often, wells of this type are additionally equipped with pumps to pump out excess moisture. Storm sewer wells differ in their purpose by type:

1. Water intake or storage wells designed to collect and accumulate water coming from the drainage pipeline. Then the liquid is poured into the nearest body of water or used for irrigation purposes, but in this case no debris or dirt should get into the storage well. It is important that the water intake structures are completely sealed - there is no bottom grid, in fact, these are ordinary large containers for storing liquid.
2. Absorbing ones have the function of draining a piece of land. An absorption well is installed in a point pattern along the perimeter of the site, draining accumulations of liquid naturally into the soil.
3. Rotary ones are indicated for installation when there is a natural or forced change in the direction of storm water flow. Such structures can be equipped with any number of pipes that drain liquid.

The collector storage tank does not have a separate type; it is intended both for collecting storm water and for clarified water coming from the water supply system used for household needs, but, in fact, water receiving storage structures can already be called collector structures. The design is often equipped with additional pipes through which the total volume of water is directed to various purposes, for example: part for discharge, and part for irrigation.

Siltation of the drainage well: causes, solutions

If the internal volume is filled with debris, sand and water stops flowing, this means that the well has begun to silt. The reasons for this phenomenon are different, however, it is quite simple to guess that the drainage system for the storm sewer is clogged: an unpleasant odor appears, and water quickly fills the container after pumping out. It is quite difficult to determine the degree of siltation, as is cleaning a drainage well with your own hands. But it's worth trying. There are several options to solve the problem:

1. Reduce water volume as much as possible. If it is a collector type, it is enough to simply pump out the liquid with a pump; the absorption well must also be emptied of water, without touching the bottom with the suction part of the pump, so as not to clog the device;
2. Carefully collect dirt from the walls and bottom with a scraper, making sure to go through all the seams; this is where a large amount of silt collects;
3. As soon as there is no water left at the bottom or the level is reduced to a minimum, the bottom is cleaned. The collector type of design has a solid bottom, so cleaning will not take much time.
4. Rinse and clean the bottom filter if you have an absorption type of structure;
5. Seal seams and cracks (if any) with cement.

If the siltation is weak, you can use a pump that supplies a stream of water. Direct the flow to wash away all particles and remove liquid. If the degree of contamination is low, it is not difficult to clean the drainage well with your own hands, but if the siltation is serious, it is better to contact a specialist.

Making a drainage well

Regardless of the type of storm sewer drainage well, you can always make it yourself. The simplest and most accessible designs are those given below:

• A concrete drainage well for storm sewers is usually a collector type and has a solid bottom. Therefore, to make a drainage well with your own hands, you need rings equipped with a solid bottom. The initial stage is digging a pit of the required depth, and only then installation is carried out, which will require special equipment. Rings are lowered into the hole, drains or pipes are connected, and you get a drainage tank for storm water, the volume of which is quite sufficient to use liquid for various needs. The method is simple, but installing a drainage well from concrete rings is expensive.
• If you have old car tires, you can make a reservoir for storm drainage from them. This design is better suited for an absorption well.

All work is divided into stages:

1. dig a hole at least 200 cm deep;
2. fill in a crushed stone cushion (it is better to use medium-fraction crushed stone) with a thickness of at least 200 mm;
3. lay several tires on the bottom;
4. fill the voids with crushed stone;
5. fill the space between the tire and the walls with medium-fraction gravel;
6. cover the resulting structure with a layer of soil or geotextile.

Installing a storm drain well of this type has many advantages, but is not entirely suitable for collector wells.

• A plastic drainage well is an ideal option for arranging the structure. Today, manufacturers offer a wide range of products with increased strength and different diameters. Thanks to the stiffening ribs, the polymer system fits perfectly into the ground and also has ready-made bends for connecting to the pipeline. Light weight, convenience, practicality, presence or absence of a bottom - these are the advantages of the models. In addition, installation will not take much time and there is no need to rack your brains on how to make a drainage well with your own hands.

Important! Plastic structures have a significant service life - up to 50 years, with less silting, are quite durable and frost-resistant.

Well installation

For work you will need the following materials:

• Corrugated pipe - the body of the well;
• Plastic bottom;
• Sealing rubber connecting the tank to the drains.

Advice! The parameters for the structures are as follows: rotary - at least 350 mm, viewing - at least 850 mm, storage - at least 600 mm.

Now you can proceed directly to the installation:

1. Prepare the corrugated pipe: cut off the required piece, drill holes for connecting drains. The pipe is inserted into sealing cuffs;
2. Dig a well of the required depth;
3. Make a cushion of crushed stone, fill it with concrete (not for absorption wells);
4. Install the bottom (if there is an absorption structure, then the bottom is not needed);
5. Install the well itself into the well: lower the pipe into the hole and attach it to the bottom, not forgetting to treat the joint with bitumen mastic;
6. Bring the drainage pipeline to the structure, connect, seal the joints;
7. Sprinkle the finished well with fine crushed stone.

When the well is completely filled in, all that remains is to cover the well and it can be used.

Finally

The volume of the stormwater well can be any - it all depends on the intensity of the liquid flow. You can always place different types of wells on your site to retain water at the top, preventing it from rolling down, which is especially good for mountainous terrain. And you already know how to make different types of drainage wells.

A storm well is located in the local area to drain the excess volume of water that forms when snow melts and as a result of rain. One of the components of a storm drainage system is a rain well, which includes:

• neck;
• mine;
• cover.

A storm well has a neck through which water enters the shaft. After precipitation it can be used. The well is protected by a lid to prevent the possibility of foreign objects getting inside.

Varieties

A storm well can be made of plastic or concrete. Most often in the latter case, reinforced concrete is used. Depending on the purpose, wells can be divided into:

• absorption;
• reception rooms;
• differential.

Description of wells

The first type of well is also called filtering. Such structures do not have a bottom, because they are located in an area below the groundwater table. The liquid that enters the absorption well goes into the ground. The storm sewer intake well is designed for areas where groundwater is located quite high.

The liquid entering such a structure can be used at the next stage to irrigate the area. In order to extract water from such a well, pumps are used. A differential storm well is installed where there are significant differences in the ground. Such designs eliminate the flow of water, which could damage the system.

Construction of a storm well

Due to the fact that such a well can be made of plastic or reinforced concrete, the installation technology for these structures is different. In the case of a plastic product, a corrugated pipe or well of the required diameter is prepared at the first stage. To carry out the work, you should ensure that you have:

• rubber seal;
• mastics;
• sealant;
• concrete mortar;
• gravel or sand.

If required, you need to prepare a plastic bottom. Seals will be needed to ensure the reliability of the connection of the elements. And for additional protection of these places, sealant should be used. You can strengthen the connections between the shaft and the bottom using mastic.

The well can be represented by a corrugated pipe. For installation, a pit and trenches for laying pipes are prepared. The soil below is strengthened with fine gravel or sand. Holes are made in the corrugated pipe that will be necessary to connect the pipes.

Using the pipelines should be connected. The joints are treated with sealant. If the well has a bottom, then it is fixed to a concrete base. At the next stage, you can begin installing the corrugated pipe.

The bottom and pipe at the junction are treated with mastic; it is advisable to use one that is made on the basis of bitumen. Along the entire perimeter, the walls of the well are covered with gravel, and then with earth. At the final stage, a protective cover is installed on top of the shaft. You can make a well yourself from plastic rings or corrugated pipes; this approach will save money.

Construction of a reinforced concrete well

If the well is made of reinforced concrete, then installing it will be much more difficult than a plastic one. To carry out the work you will need:

• concrete rings;
• cement mortar;
• concrete slab;
• lifting equipment.

The bottom of the well will be a slab. To seal joints, in addition to cement mortar, plaster and bitumen should be prepared. At the first stage, it is necessary to dig a hole and trenches for pipelines. A concrete slab is installed at the bottom. An alternative solution is to pour the base from a concrete mixture. The foundation and rings are treated with bitumen, which significantly extends the service life of the products.

As soon as the slab is dry, you can begin installing the rings, but you cannot do without lifting equipment. It is important to avoid distortions. The joints between the rings are treated with cement mortar and bitumen. After these materials have dried, you should start finishing the walls with plaster.

Sand should be poured into the bottom of the well. Soil is used for backfilling. All layers are compacted using special equipment or a shovel. At the final stage, the well is closed with a lid, and a blind area is made around it. Its width should be 150 cm or more. This will strengthen the structure.

Distribution well device

A storm sewer distribution well is usually a container made of durable fiberglass, which quite often has reinforced walls. This design is equipped with inlet and outlet channels. The container is closed with a lid. There is usually one input channel, while there should be two output channels, they are organized at different levels.

The distribution well is equipped with a ventilation pipe. The design is intended for distributing water and supplying liquid to treatment facilities. A ladder is provided inside the housing for ease of maintenance. The well neck has a diameter that is usually 60 cm. This allows you to install a cast iron sewer hatch on top. Structurally, it is possible to install a plastic hatch. This is true when the well is located in a green area.

Drainage well

A drainage well for storm sewerage is located in places where moisture accumulates most often, this includes depressions in the ground, as well as the area under the drainpipe. Such a reservoir has the form of a vertical drainage pipe into which ground and surface water flows. The throughput of the structure is quite high.

If we are talking about linear storm drainage, then in this case the walls of the drainage well are additionally reinforced with concrete rings. However, when considering the issue from the point of view of economy, it should be emphasized that the most profitable option for a mine is a plastic well in the form of a structure with connected drainage pipes. The walls are strengthened with casing pipes, the diameter of which varies from 300 to 400 mm.

Carrying out cleaning

You already know the structure of a storm well; this was discussed above. However, for proper operation it is important to know not only this. Experts recommend familiarizing yourself with the cleaning features. The described system requires maintenance. After all, it can be clogged with sediment and accumulated debris. Manipulations can be carried out in the following ways:

• thermal;
• chemical;
• hydrodynamic;
• mechanical.

The mechanical method is most often used to clean individual systems. It involves manually removing dirt from gutters, storm drains, and liquid treatment systems. To do this, you can use brooms, mops and special devices with tips.

The hydrodynamic method is also quite common. It involves the use of high pressure technology. The destruction of blockages is carried out under the influence of a stream of water. Cleaning storm wells using this method involves the use of household pumps that supply water from a source, which can be specialized equipment.

The thermal method differs from the above in that water enters the sewer under high pressure and at a high temperature ranging from 120 to 140 °C. An advantage of this approach is the ability to clean the system from dirt and debris, as well as fatty deposits.

Conclusion

The reservoir described above acts as the final point that should be set when arranging a surface drainage system. Considering the varieties of such structures, it is necessary to highlight stormwater intake wells. They are installed where groundwater is high. This well receives water, which can then be used to water plants. The principle of operation of such a system is the accumulation of liquid and its subsequent use.

About plastic wells

Plastic inspection and drainage wells designed to control the operation of drainage and sewer systems. Previously, such wells were made of concrete rings. Their advantage is the ability of a person to go down into the well, the disadvantage is the inconvenience of delivery and installation.

Currently widely used plastic wells, made from plastic corrugated pipes of various diameters (from 300 mm and more) and colors (black, orange). Such wells are easy to deliver and install; a variety of multifunctional components are produced for them. All types of wells are made from corrugated plastic pipes: inspection wells, catchment wells, drainage wells, storm wells, sewer wells.

For device inspection drainage wells a shaft with a diameter of 300 mm or 400 mm is sufficient. The height of the well is determined by the lowest point of the outlet pipe. 20 - 40 cm are added to this mark to form an inspection chamber at the bottom of the inspection well. Thus, the height of the inspection drainage well should be equal to the depth of the drainage pipe plus 20 - 40 cm.

If you plan to install drainage well equipped with a pump, the recommended shaft diameter should be at least 500 mm. The height of the well is selected taking into account the organization of the lower chamber for installing the pump, which requires an additional 50 - 100 cm. That is, the height of the drainage well "under the pump" should be equal to the depth of the incoming pipe plus 50 - 100 cm.

For equipment plastic well for sewerage apply walk-through inspection bases, which form the lower part of a plastic well and are made in the form of a tray with a given slope and with sockets for connecting a sewer pipe D 110 mm, 160 mm, 200 mm. Such bases can be straight through or have additional tributaries on the right and left sides at an angle of 45 degrees. That is, there can be several entrances to the viewing base, but there is always one exit.

Thus, a plastic inspection well for drainage differs from a plastic well for sewerage. In the first case, there must be an inspection chamber with an additional height of 20 to 100 cm; in the second case, the bottom of the well is an inspection passage base.

Accessories for plastic wells

	Well shaft - corrugated plastic well pipe, diameter 300 mm, 315 mm, 400 mm, 425 mm, 500 mm, 600 mm, 800 mm and more
	Bottom of a plastic sewer well- walk-through inspection base with a formed slope of 1, 2, 3 entrances at 45 degrees
	Bottom/cover of plastic well - plastic plug with handles, with an O-ring, used as a bottom or cover for filling
	Plastic well cover/hatch - plastic hatch with bolts, load 1.5 t
	Coupling for inserting a pipe into a plastic well in situ, diameter 110 mm, 160 mm, 200 mm
	Check valve for installation in a plastic well for pipe 110 mm

Assembly of plastic wells

	1. A corrugated pipe of the required height is completed with a bottom and installed in place for preliminary joining with incoming and outgoing pipes. 2. The pipe is inserted into the well using "in situ" couplings. A hole is cut in the wall of the well using an end mill to the diameter of the coupling. 3. The pipe entrance to the inspection well must be located at a distance of at least 20 - 50 cm from the bottom of the well. Thanks to this, you can monitor the water level in the system, and the lower part of the well also acts as a garbage container.
	4. For sewer wells, walk-through bases of various configurations are used according to the number of incoming pipes and the entrance angle. 5. If necessary, install a check valve at the end of the pipe entering the well.

Installation of plastic wells

Plastic wells are installed directly into the drainage trench and, after assembly, are covered with sand. Thus, thanks to the corrugated wall and sand coating, long and reliable operation of the well is achieved and it is not allowed to be “squeezed” out of the ground even in the coldest winters.

In what cases is a closed storm sewer constructed? What types of storm wells are there? What materials are they made from? Let's figure it out.

Open and closed storm drains

The difference between them is intuitive; however, let's take the time to describe both systems in more detail.

An open storm drain consists of gutters (most often concrete) laid along the surface of the ground. They are laid, of course, with a constant slope along the water flow.

The price of gutters and auxiliary materials (sand, cement, etc.) is low; however, such a scheme has a number of limitations.

1. The slope of the gutter is forced to follow the terrain with slight deviations in one direction or another. This is not always how water will be transported in the direction you want.
2. Debris, sand, branches and leaves often create an insurmountable barrier for drains. Of course, cleaning it doesn’t present any particular problems, but... do you really want to do this in a rainstorm?

A closed storm drain completely solves the problems described.

1. The slope can be created in any direction. Of course, sometimes this means a significant amount of excavation work.
2. Sand traps or grates, which are equipped with wells for storm drains, prevent large debris from clogging the storm drain.

However: the gratings, of course, will not protect you from seasonal problems with ice jams. This primarily applies to cold regions with a significant depth of soil freezing.

In what cases is each of the described schemes preferable?

The instructions are simple and obvious.

• Open gutters are a great solution for a small area with a constant slope.
• Difficult terrain and large areas will force the use of underground storm drainage.

Elements

What does an underground storm drain consist of?

Pipes

It is clear that the main element is a pipe dug into the ground, which, in fact, transports water. It is laid in the ground with a constant slope of about a centimeter per linear meter. Currently, ordinary sewer pipes made of polyvinyl chloride with a diameter of 110 - 200 millimeters are used for household plots; In urban storm drains, large-diameter reinforced concrete pipes are used.

Reception well

What constitutes a receiving storm sewer well is also quite clear. Moreover: each of us stepped on or ran into their bars many times.

Actually, before us is an ordinary vertical shaft with a diameter of 60 centimeters, protected from debris from above. It is usually located at the lowest point of the relief area; This ensures natural water flow. The depth of the well (as well as the depth of the pipe) should prevent it from freezing during transition seasons, when a warm day may give way to night frosts.

Inspection well

An inspection storm well is usually installed where the sewer pipe turns or changes slope. The purpose of its construction is to provide access to network segments for cleaning, thawing and repair.

What does a manhole look like? In its simplest form, this is the already familiar vertical shaft with an open tray laid along the bottom, into which pipes open on both sides at the same level.

Curious: a manhole can combine several pipes coming from the receiving wells. In particular, its construction is highly desirable at the point where branches from several sections are connected to the collector.

Drop well

Drop-in storm sewer wells are installed in the following cases:

1. The need to miss the underground highway. For example, when a storm sewer intersects with a water pipeline laid at the same depth, a pair of differential wells allows you to bypass it higher or lower.
2. The desire to force, regardless of the terrain, to create an acceptable slope for the gravity movement of rainwater.

The basic design is ridiculously simple: two pipes lead into a well shaft at different levels.

However, when designing a drop well, two problems have to be solved:

• Water falling from a great height will create a fair amount of noise.
• In heavy rain and with a significant drop, a strong stream is quite capable of gradually destroying the walls of the well.

What could be the solutions?

1. The water tray is made sloping, thereby eliminating the fall of water on the surface perpendicular to the stream.
2. The supply pipe is equipped with an elongated tee, almost reaching the bottom level.
3. A reflective screen is placed in front of the supply pipe.
4. The walls of the well are equipped with several shelves for water with a slight difference between them.
5. Instead of one chamber, two wells are installed, connected by a pipe with a large slope.

Materials used

Is it possible to build a storm sewer well with your own hands? Can the current market offer any ready-made solutions?

Concrete rings

They are very popular when installing storm drains in cities.

Construction is quite technological and takes a moderate amount of time; however, for a private home this is not the best solution:

1. Reinforced concrete rings are not cheap.
2. To install them, you need a crane, which is also not free, and it won’t go everywhere.

Brick

Unlike rings, brick walls are easy to lay without the use of machinery. This job requires minimal construction experience.

You just need to follow a few simple rules:

• A concrete pad is formed under the wall by adding crushed stone.
• The wall is laid with at least half a brick, with horizontal rows interlaced.
• Only and exclusively red solid bricks are used. Silicate quickly collapses in dampness, while hollow in the cold will suffer from crystallization of water in its pores.

The top of the brick well is covered with ready-made concrete tiles with a hatch.

Plastic

Thanks to the combination of relative cheapness and durability, polyethylene and polypropylene wells are rapidly gaining popularity. Their manufacture from corrugated thick-walled pipe allows us to solve the main problem of plastics - low ring rigidity.

In addition, when installing plastic wells, you should adhere to a couple of simple rules.

1. At high groundwater levels, products with loading chambers are preferable. During installation, they are filled with concrete and prevent the well from floating in wet soil.
2. To increase the rigidity of the structure, smooth-walled wells are backfilled with a cement-sand mixture in a ratio of 1:5. When laying, the mixture is compacted every 20 centimeters.

Drainage well: plastic, concrete, storm sewer wells. This article will examine in detail a concrete and plastic drainage well for storm sewers as one of the options for a system designed for suburban areas. You will be able to familiarize yourself with the main classification, find out the characteristics of structures, their features, advantages and disadvantages. This material will help you understand the technology for arranging such a system on the territory of your summer cottage.

Storm drainage on site

Concrete and plastic drainage well for storm sewerage: classification

After spring melting of snow or heavy rainfall, water may accumulate on the site. If liquid lingers near a house for a long time, the moisture can erode the soil underneath and destroy the foundation. Exposure to high humidity leads to the formation of cracks in the foundation of the building and on its walls, which can ultimately lead to collapse.

Visualization of the drainage system in the local area

Note! Organizationexternal storm drainageon the site completely solves this problem and eliminates all the consequences associated with it. All excess moisture will flow into the well, from where it will be removed naturally.

Features of storm drainage around the house: general provisions

If you correctly design and implement storm drainage in a private house, this system will ensure the collection of rain and melt water from the surface of the ground and roofs of houses, and also organize the effective removal of excess moisture from the site.

The place for draining liquid from the stormwater system can be:

• soil (septic tank type design);
• the nearest body of water (river, lake);
• ravine;
• home sewer system.

There are two technologies in a private home. One type of system belongs to the linear type of structure, the other to the point type.

Storm drainage can effectively prevent the negative impact of excess precipitation

The design, operating on a linear principle, ensures the collection and transportation of excess moisture not only from roofs, but also from other surfaces on the site:

• parking areas;
• blind areas;
• paved paths, etc.

Unlike point-type sewerage, in this case, not rainwater funnels, but gutters are used to collect water. These system elements are mounted flush with the sidewalk in accordance with the general slope. The structure is equipped with filters and covered with special grilles.

The operation of point sewerage is based on several rainwater receivers. They collect liquid flowing down gutters from the roof of the building. The secret of installation is to correctly connect all the elements of the system into one large highway. Through it, water will move to drainage wells for storm sewers.

Storm drainage is an integral attribute of landscaping of a residential area

Then the liquid is pre-cleaned and discharged to a place specially designated for this purpose.

Helpful advice! When installing rain gutters, be sure to install gratings on them, as well as filters.sand traps for storm drainage. These elements will trap large debris and sand. The price of sand traps ranges from 800-2500 rubles/piece.

Types of storm sewer wells for a private house

First of all, the classification of storm wells into groups is carried out on the basis of the material from which they are made. The material of manufacture directly affects the properties of the well and determines its characteristics, both technical and operational. The most common and most used systems are plastic and concrete products.

The classification of drainage wells for drainage of groundwater by type of construction is as follows:

• absorption;
• examination rooms;
• receptions.

Plastic varieties of systems have an expanded range of designs, due to the practicality and versatility of the material from which they are made.

The main function of drainage wells is to control operation and timely clean drainage pipes from clogging

In addition, the design of storm sewer treatment facilities can be:

• monolithic (concrete);
• collapsible (plastic).

In each case you are dealing with certain advantages and disadvantages.

Plastic drainage wells and their features

Wells with a collapsible design, made from plastic, consist of several elements:

• bottoms;
• mines;
• sewer hatch.

The shaft is the most important part of the product. It is a smooth, and in some cases corrugated, storm sewer pipe with thick walls and a large diameter.

Helpful advice! Use pipes with a corrugated surface in your work, as they reduce the loads that affect the bottom of the well during its operation.

The inspection well is designed for inspecting and cleaning the drainage system

To make the bottom and sewer hatch in such structures, manufacturers use an artificial material with an increased safety margin - polypropylene. Depending on the location of the drainage well, a hatch of a certain strength level is selected. Some of them are equipped with stairs for convenience.

On sale you can find hatches designed for:

• park areas;
• sidewalks and pedestrian paths;
• highways;
• highways located within the city limits.

Three types of raw materials are used as material for the manufacture of plastic wells:

• polyethylene;
• polyvinyl chloride;
• polypropylene.

Installation of a drainage system

The choice of material is also dictated by the location of the system and its purpose. If desired, during installation of the product, a drainage pump for the well can be installed.

Types of drainage pumps for pumping water from a well

Depending on the type of installation, submersible and surface pumps can be used to service drainage systems. During installation, submersible models are placed directly into the water column using a cable. Having reached the required mark, the device is secured. This type of pump is located at the depth of the drainage well with a distance from the bottom of approximately 50-100 cm.

Advantages of submersible models:

• compact size and light weight;
• long periods of effective service without maintenance;
• wide range of capabilities (ability to work with liquids of varying degrees of contamination);
• high efficiency (40 m³/h);
• float protection simplifies the system to use;
• the device can be automated by connecting to other systems.

Submersible pumps are designed for pumping both clean and contaminated liquids and wastewater

The disadvantages of the devices include low pressure, especially if the pump is installed at a considerable depth. When liquid is pumped, the water filtration process is not possible, and this complicates the operation of the system.

Note! Submersible models can have a vibration or centrifugal operating principle. In the first case you get accessibility, in the second you get high efficiency.

In drainage systems for drainage of groundwater, surface pumps can also be used, which are characterized by:

• high pressure;
• long service life;
• affordable cost;
• economical in terms of electrical energy consumption.

Surface pumps allow you to pump out water even from shallow depths

Surface pumps also have disadvantages: high noise levels during operation and restrictions on suction depth. Such devices cannot work effectively if the well depth exceeds 8 m.

Specificity of absorption drainage wells and other plastic systems

Inspection drainage wells are used to visually monitor the condition of the system. Thanks to this you can:

• monitor the operation of the system and its uninterrupted operation;
• perform maintenance work;
• clean the pipes in a timely manner and monitor the condition in which they are.

This well has a standard structure. The exception is the bottom, which in this case has a tray part where the grooves are located.

Absorption wells are used when the site does not have conditions for water drainage. Such models do not have a bottom. At the bottom of the structure there is a sand and crushed stone cushion, which act as filters, passing purified water into the ground.

Operating principle of an absorption drainage well

Under such conditions, a ground collapse may occur. To prevent this, experts recommend using round plastic wells. If you plan to build a rectangular or square absorption well, you should pay attention to other materials, for example, brick or concrete.

Storm sewer receiving wells operate on the principle of accumulating liquid and then discharging it. For these purposes, not only the drainage system can be used, but also natural reservoirs, as well as ditches.

Note! Such structures necessarily have a solid bottom and a lid without holes, since, accumulating in the system, water can completely fill it.

Installation of a storm well

When constructing such a plastic drainage well, the pipes are inserted at a certain level. You should retreat at least 40 cm from the bottom to provide enough space for sand and other impurities that may be contained in the water to settle.

Advantages and disadvantages of plastic drainage wells, price of structures

Owners of country houses prefer to buy a plastic drainage well rather than deal with the complex installation of a concrete structure. And there are several explanations for this, since plastic structures:

• They are light in weight, and, therefore, their installation does not require the use of special equipment and significant effort;
• completely impenetrable;
• are characterized by increased endurance (service life reaches 40 years);
• are not afraid of exposure to weather conditions;
• easy to use.

Welded plastic wells for water supply and sewerage

Despite the extensive list of advantages over concrete wells, plastic systems have some disadvantages:

• high price compared to concrete products;
• when installing storm sewers, plastic wells can be installed to a depth of no more than 15 m. With regard to concrete structures, there are no significant restrictions on depth;
• All installation work must be carried out carefully and carefully, since there is a possibility of deforming the plastic.

Features of drainage wells made of concrete rings

As is the case with plastic systems, wells made on the basis of concrete rings perform the function of water drainage. The modern range of designs includes similar types of inspection, storage and absorption wells, operating on the same principle as the previously described plastic products.

Note! There is another type of concrete well - rotary. When organizingdo-it-yourself storm drainage system in a private house, such structures are installed in areas where system pipes are connected at an angle.

Advantages of concrete products:

• installation is carried out in one day;
• the structures are completely sealed;
• do not require constant care;
• have a low cost;
• do not put forward special requirements for the type of soil (can be installed even in areas with heaving or moving soil).

Construction of a concrete sewer well

The only disadvantage is the heavy weight, which is why work on constructing a drainage well from concrete rings cannot be done without the involvement of specialists and the use of heavy equipment.

Prices for the construction of a concrete well:

The price of concrete drainage wells indicated in the table includes the cost of materials and payment for the work of specialists.

Recommendations for constructing a drainage well with your own hands

It should be remembered that storm drainage is a system of pipes and other elements aimed at removing excess liquid from the site. Its main components:

• gutters and trays used to drain liquid;
• pipes through which water is transported to the right place;
• storm water inlets equipped with gratings;
• inspection well structures for monitoring the system;
• storage structures that collect wastewater from the entire system;
• filter elements (sand catchers).

Note! Before starting work, be sure to readSNiPs: slope of storm sewer by 1 meter, as well as the area where the well is located, as well as other parameters of the system must comply with regulatory requirements.

The safety and integrity of the foundation and blind area of ​​a country house is ensured by the installation of plastic rainwater inlets

Most systems are equipped with additional components that provide ease of use. Such components include alarm systems that notify of a well overflow or the presence of blockages in a storm drain.

Installation of these parts is carried out in storage and inspection type wells. Such warning systems greatly simplify sewer maintenance.

Storm sewer calculation: SNiPs and preparation

Before you start building a drainage well with your own hands, you should perform a number of preparatory steps:

• determine the type of construction;
• perform calculation;
• purchase the right materials;
• prepare the site for construction.

Modern system for collecting and draining surface water runoff

The development of the project is carried out in accordance with the conditions dictated by your site, namely:

• the nature of the placement of underground communication systems;
• annual as well as seasonal precipitation;
• the intensity with which precipitation falls in your region;
• drainage area;
• the type of coating present in the area to be drained;
• volumes of wastewater, including storm water and liquid coming from the roof.

Based on all of the above conditions, as well as the throughput of roof drains, the diameter of the pipes for the system is calculated. When developing a pipeline laying plan, be sure to take into account the specificity of the terrain located in the sewerage construction area.

Most often, for construction in private areas, pipes with a diameter of 10-15 cm are used. Moreover, in accordance with the requirements of SNiPs, the slope of a drainage pipe per 1 meter must be at least 8 mm.

Installation of a storm drainage system

The same regulatory documents also regulate the depth of pipe installation. If you purchased elements with a diameter of no more than 20 cm, they need to be laid in the soil to a depth of 30 cm or more. The laying of the sewer system in the northern regions should be carried out below the soil freezing level.

Helpful advice! To reduce the required pipe depth according to standards, use insulating material.

Installation of a drainage well: how to install a storm drain

Many people try to install a drainage well on their site with their own hands; this step-by-step diagram describes how to do this procedure correctly:

• an external drainage system is being installed, namely roof drains, as well as linear sewer gutters;
• guided by previously drawn up calculations and a plan, it is necessary to form trenches in the soil for laying the pipeline at the appropriate depth;
• a sand cushion is placed at the bottom of the trenches to maintain the required slope;
• installation of trays or pipes is carried out, after which all these elements are interconnected into a single system;
• Stormwater inlets are installed under drains located on the outside. These elements must be properly sealed, not forgetting to install garbage collectors and grilles;

Installation of rainwater inlets under gutters

• To install a drainage well, you need to dig a pit. Inspection-type structures are installed in places where the pipeline branches, as well as long sections of single pipes. Areas where several branches combine are suitable for placing collector wells. If you correctly distribute the elements of the system, it will be effective and last longer.

All elements of the system must be connected to each other, checked for integrity, and tested. After this, the trenches are filled with earth and compacted.

Helpful advice! If you do not want to carry out a complex installation of a concrete well or purchase an expensive plastic product, you can limit yourself to manufacturingtire drainage well.

Scheme for making a well from tires:

1. Organize a hole 2 m deep (calculated for 5-7 car tires). The diameter of the hole should be 50-80 mm larger than the diameter of the tire.
2. Make a drainage well at least 5 m deep.
3. Install the drainage pipe yourself.
4. Form a layer of crushed stone at the bottom (10 cm).
5. Stack the tires one on top of the other.
6. Fill the free space of the well between the tires with soil (from the outside of the well).
7. Organize the cover based on reinforced concrete or plastic.

When installing the system, do not forget about the pump. Depending on its design, installation is carried out at a certain stage.
