The device of storm sewerage in the country. Reliable storm sewer - guaranteed protection of the site from the flood. Accurate Slope Rates

Arrangement country cottage requires the solution of many engineering and construction issues. In addition to creating convenient and comfortable conditions for living inside the house - you also have to equip the garden plot. One of the important buildings on suburban area is a storm sewer in the country.

Protecting yourself from the weather

In our country, there are practically no areas where there is no precipitation. AT middle lane In Russia, the volume of rainfall and water from melting snow can be measured during the year in cubic meters. In addition, not a single cottage is immune from heavy rain, which in a limited time can oversaturate the soil in your area with moisture and turn it into a natural swamp.

After your dacha is covered pouring rain- Fallen water will run off roofs and hard, non-absorbent areas into the ground, excessively saturating it with moisture. Not only can this moisture create problems for your crops, but it can also cause your home's foundation to collapse. If there is a cellar ground floor or a basement in your summer cottages - water can penetrate into these rooms and partially flood them. The same situation with an excessive amount of moisture on the site can also develop during the intensive spring melting of the snow cover.

To protect against the adverse effects of moisture, household plots suit storm sewer, which removes excess moisture outside your dacha, where it cannot damage anything.

The main characteristics of storm sewers

The storm sewer system is a rather specific structure. Unlike conventional plumbing, rain and melt water contains a large number of both large debris and small suspended particles. Such a composition of the flow implies primary treatment and the creation of a channel for the uninterrupted movement of littered water.

The composition of the storm sewer system in the country

The composition of the storm sewer system is not limited solely to drains that collect rainwater from the floors of structures. Rain pipes are just one of the constituent parts storm drains.

In the storm country sewerage the following main components can be distinguished:

Elements that divert rainwater and moisture from melting from various sites overlays or terrain.
Elements that collect diverted melt water away from beds or houses.
Elements that allow you to accumulate or reuse the accumulated moisture.

It is also worth noting that storm drainage can be created using two constructive methods: linear and point, or a combination of both.

Spot storm sewer in the country

When using this method of collecting rain or melt water, runoff is collected from hard, non-absorbent surfaces, for example roofing or paved areas. The effluent is then directed to the receiving funnels. After collection, wastewater is transported to the drainage system.

Linear storm sewer in the country

When using a linear diversion system, all drains from non-absorbent surfaces are drained into gutters located along such areas. After collection, rain and melt runoff is sent to the drainage system. If there is a border with a ravine or a reservoir on your site, it is advisable to direct the drains towards the natural flow. As an option, rain and melt runoff can enter the purification plant, where it undergoes primary treatment.

The recycling of rain and melt water is a very profitable undertaking. With it, you can achieve substantial savings on water bills for irrigation or cleaning. Rain and melt runoff carry relatively few pollutants and their treatment in a standard septic tank should not be a particular problem.

We independently mount storm sewers in the country

Despite the fact that storm sewerage is quite complex engineering system- you can easily install it yourself. The situation is facilitated by the fact that there are no pressure pumps in the storm sewer system, and the water in it moves by gravity. Therefore, the installation of stormwater in the country or in country house is only a more technically advanced baby needle with spring streams. In order to competently design and install the drainage of rain or melt water in the country, you need to have only minimal technological skills.

Storm sewer installation technology

On the initial stage calculation of the storm sewer system. Minimum necessary elements is a system for draining water from buildings, since rainwater when it is overabundant, it can seriously complicate your life. Further, if necessary, drainage from paved paths and areas, for example, from an asphalt parking lot, is calculated.
Having determined the areas from which water should be drained, it should be done so that rain moisture does not linger on such surfaces. Everything is clear with the roof - water is collected from it by standard drainage system. But in order for your paths or parking in the country house not to be covered with water after every rain, during their construction it is necessary to provide for a slope along which water under the action of gravitational forces will roll into water intake funnels or gutters. Similar funnel devices or gutters are installed under the endings downpipes collecting moisture from the roof.
After the calculation and construction of all funnels or gutters - the collected water must be discharged away from the site, or into the wastewater treatment system.
Water can be drained from water intakes by closed or open way. When using the open method, water enters the gutters, closed at the top with gratings. When applied closed system water enters the collection and discharge point through an underground pipe system.
Both when laying gutters and when placing pipes, building drainage structures should be placed with a slope towards the catchment. The angle of inclination of the catchment pipes and gutters is calculated in the same way as when laying an outdoor sewer system.
When laying pipes and gutters, after digging in the selected place of the trenches, a sand cushion with a thickness of at least 10 centimeters is laid on their bottom.
The pipes of the drainage system in the ground can not be buried by a significant amount. Storm sewage works exclusively in the warm season and the problem of freezing does not threaten it.
In order to prevent the system from becoming clogged, it is necessary to provide for the installation of gratings-filters for collecting large debris and sand traps for collecting suspended solids. small particles such as sand. At the locations of filters and sand traps in underground closed laying pipes, it is necessary to provide for the presence of inspection wells and hatches for routine maintenance and unscheduled wastewater treatment.

Features of the installation of storm sewers

For laying storm sewer gutters in an open way, you can use ready-made solutions - concrete and plastic gutters for storm sewers.

Also, storm sewers can be combined with a drainage system. In soils with large quantity moisture requires constant removal from excess water. To do this, pipes with holes are laid in the ground, which collect moisture and soil and divert it away from the site. The same pipes can also be used to move outside the area of rain or melt water. However, as a rule drainage pipes are laid at a depth greater than the storm sewer system.

Carefully calculate the slope of the drainage pipes. Use building level or a special theodolite.

Please note that water is a rather aggressive environment, so make a sewer storm system exclusively from materials that do not subject to corrosion such as plastic or reinforced concrete. Do not use pipes with a corrugated surface, as they are extremely susceptible to clogging.

Water can find a way out anywhere, so when connecting storm sewer pipes, use sealed technologies similar to conventional outdoor sewers.

In order to prevent the water in the storm water from freezing in winter time- at the beginning of frost, the system must be completely cleaned and freed from water.

All entrances to water collectors and storm gutters must be covered with gratings. It is easier to rake the leaves from such gratings than to get them out of the bowels of the sewer system later.

At each turn of the drainage pipe there must be an inspection hatch or well.

In order to learn more about the technology of building storm sewers in the country, check out the video tutorial.

Storm sewerage in the country: video

Storm sewage is a system of devices and channels used to collect rain and melt water, as well as filter it and discharge it into special reservoirs, wells or drainage fields.

Storm sewerage in the country

Such a complex is necessary to organize the protection of the foundation and walls of the building from the ingress of an excessive amount of water on them, which has a detrimental effect on the technical condition of the entire structure.

Also, storm sewers can prevent the appearance of puddles on the site and the site near the house, which are formed due to poor bandwidth soil or a sharp increase in the level of groundwater due to precipitation and snowmelt.

Storm drain prevents puddles

What is a storm sewer device

If you want to make a storm sewer device with your own hands, you should consider the main elements of the system.

They are listed as follows:

gutters and trays - are special channels located on the land, used to transport rain or melt water to drainage wells;
pallets - they are placed at the porch of the house in order to collect water flowing from the roof and further transport it to the channels. Pallets can be made of plastic or concrete;
rain pan
sand traps - they are installed between the channels and the drainage well in order to filter drains and prevent various debris from entering the well;
sand trap
storm pipes - made of durable polypropylene, have perforation. Their inner surface is smooth, and their outer surface is corrugated. Such pipes serve to divert excess water from the soil into a receiving well;
Storm pipes for storm sewers
sewers are the end point of storm sewers. It is here that water enters from pipes and gutters. Such structures can be made of plastic or concrete, if we are talking about the installation of storm sewers with our own hands;
Storm collector
storm wells - they are needed to provide access to the collector for the purpose of maintenance. But, it is worth noting that in the areas they are very often installed as complete replacement collector.
This is what rain wells look like

After all the components of the storm sewer have been considered, you should learn about the methods for calculating the system. The calculation must necessarily precede installation.

Storm sewer design and preliminary calculations

To understand how to make a storm sewer with your own hands, how much material you need to prepare for the work, you need to draw up a system project.

It will allow you to accurately determine the number and parameters of gutters and drainage pipes, as well as make it possible to mark the most good places for the arrangement of water intake trays.

In addition, with the project you will make a storm sewer that the best way is suitable for your site, because if it is of a smaller volume, it will not be able to cope with all atmospheric precipitation, with a larger volume you will simply spend extra money.

To draw up a project, you will need the following data:

the amount of precipitation falling in the area where your house is located;
information about the thickness of the snow cover, the frequency of rains;
the area of the roof in the projection on the plane, the area of the land plot on which the drainage will be equipped;
characteristics of the soil on your site, the level of groundwater;
the location of all underground communications.

Drafting a storm drain

In order to find out which pipes for drainage and storm sewers you need, you need to determine the volume of water that ready system will have to withdraw.

There is a special formula for this: Q=q20*F*Ψ. In this formula, the unknowns are deciphered as follows:

Q is the total volume of water that will need to be diverted to the storm sewer system;
q20 is the intensity of precipitation;
F- total area surfaces from which water will be discharged;
Ψ is a correction factor. It depends on the coating material of the area from which water will be drained.

Stormwater and drainage pipes

The correction factor will be as follows:

0.4 - for crushed stone coating;
0.85 - for a concreted area;
0.95 - for an asphalted area;
1 - for the roof.

Further, the result obtained after the calculations must be used to determine the diameter of the pipes. This can be done in a special SNiP table.

Table of SNiP pipe diameters

To start creating a project, do the following:

mark the location of the water collectors depending on the type of sewerage: point or linear;
calculate the amount of materials used for stormwater and drainage;
indicate the diameter of the section of drainage pipes and the depth of their occurrence;
note the indicator and direction of the slope of pipes and gutters. Usually it is 1 cm for every meter;
prescribe the dimensions of trenches and ditches that need to be equipped;
select the location of the revision wells;
indicate where the drainage well for storm sewers will be located;
mark the connection point drainage system to the water well.

Scheme of storm sewer at home

Before starting work on arranging the system, you will need to study SNiP.

SNiP

For the arrangement of storm sewers, it is necessary to carefully study the norms of SNiP 2.04.03-85.

This will allow you to more accurately and correctly determine the characteristics of the future system.

slope for pipes: it depends on the diameter. With a pipe diameter of 110 mm, the slope should be 20 mm per meter of the product. With a diameter of 150 mm - a slope of 8-10 mm and with a diameter of 200 mm - 7 mm per meter;
sewerage depth: for pipes with a diameter of less than 500 mm, the depth should be approximately 300 mm; for products of a larger diameter, the laying depth increases to 500 mm. At the same time, there should be a distance of 700 mm between the upper edge of the pipe and the ground level;
the frequency of the location of the manholes depends on the diameter of the pipes. For products with a diameter of 150 mm, wells should be installed every 35 meters, for pipes with a diameter of up to 450 mm - every 50 m, if pipes with a diameter of 600 mm, then wells should be located at a distance of 75 m;
for private plots, it is determined that the diameter of the well should be 1 meter.

Storm drainage layout

Now that we know what parameters it should match storm drainage, you can begin to arrange it.

How to make a storm sewer

You have to perform the following sequence of work:

Storm sewer installation

dig trenches in the quantity and size specified by the project;
install rainwater funnels in places where rainwater is drained;
align trenches, equip at the bottom sand cushion height 10 cm;
connect funnels with pipes, lay the latter on a sand cushion. Can be pre-wrapped with geotextile. This will help protect the system from silting and freezing;
check the compliance of the slope of the pipes to the side drainage well generally accepted standards;
connect the pipes to each other using special couplings made of the same material;
connect the drainage pipes to the well, before installing a sand trap that filters water from mechanical impurities;
fill the pipes with a layer of crushed stone with a fraction of 16 mm and a layer of soil.

Do-it-yourself storm sewer - a worthy project to protect your home

So do-it-yourself storm sewer will be equipped very quickly and simply.

When buying a plot and a house outside the city, you need to take care of many things. Security systems, fire control, territory protection, landscaping. In the turmoil of affairs, such things as the removal of wastewater from the territory are forgotten. The accumulation of melt water negatively affects the soil of the house and land plot. Storm sewers do an excellent job with this task. What it is and how it affects life in your home - later in the article.

The storm sewerage system is the main help in draining wastewater from rain and melt water from the site during the operation of a residential building on it. The accumulation of a large amount of water after rain or the remnants of melted snow has a direct impact on the yield, condition and destruction of building elements. To avoid the destruction of the foundation, cracks and chips in the elements of a private house, a storm sewer is installed, which is popularly called "stormwater". The storm sewer consists of various pipes, siphons, plugs, etc. These elements are included in its scheme, and during installation they are taken into account in a strict order. For this type of excess water flow from the site, there is one goal - to get rid of excess moisture sending it down the drain.

In a private house, this must be taken into account even when modeling the site. By creating a model, you can position the storm drain so that it will not create inconvenience.

The entire storm sewer system consists of elements, the installation of which is best entrusted to professionals. There are 3 types of storm sewers: open, closed and mixed. When installing with your own hands, you must strictly follow all the rules for combining elements and fastening.

Features of stormwater types:

open type. Often used in private areas. With help special solution, a certain system of channels into the soil is created. Sheltered with special gratings. They are removable. Forging lattices can be perfectly combined with the landscape on the site.
closed type. Used in areas with large area. All elements are installed in the ground. Water passes through the sewer and is pumped out of it with the help of a pump. This type of sewerage is installed not just in the country, but throughout the entire suburban village.
Mixed type. The collection of water occurs on the surface of the earth, and its distillation underground. Storm drains are installed in such a way that water passes through them on its own.

Installation and installation of this type of drain is point and linear. Spot installation helps to collect all the water on the roof. The drain and pipes are a kind of conductor of water in this system. Rain and melted snow fall into the storm water inlet and go into the well at a certain slope. Water leaves the territory of the site through pipes located around or is absorbed by the soil. The well needs some kind of water level control in case of a large accumulation of water. This type of sewage can also be on the ground, with a grate installed on it to prevent contamination from entering it.

With linear installation, sewerage is used as a continuation spot mounting, or as a stand-alone drainage system. They like to install such sewers using road directions.

Stormwater is a sewage disposal: the importance of the scheme

Before you make storm drains, you need to decide on the scheme of its laying. The location is chosen based on places with a large accumulation of water. Most often, these are places with vertical drains. Under them it is necessary to install a device for collecting water of a cone type. Therefore, the zero point in the coordinates of the water drainage installation will be the point of its accumulation.

Before installing this entire system, a diagram is drawn, all the main dimensions are entered.

All water collectors are combined. Later they are connected with a gutter to a well. This is how all the water leaves the roof. Wells are selected based on the material that goes in the manufacture of such a design. Most economical option brick, and more expensive - polymer.

What is taken into account in the scheme:

Pipe parameters: length, width, material;
How many fittings are needed for installation;
Number of water collectors;
Number of drainage wells.

At the moment polymer materials are leaders in application. It is recommended to install solid containers. But a metal well will have to be assembled, and this procedure must be done repeatedly.

Necessary elements and installation of storm sewers in a private house

Outdoor storm sewer in the house is the protector of the soil, crop and building. With soft and wet ground, the building itself becomes unstable and dangerous. It may sink or tilt, which will lead to large loads on the walls and may be dangerous for people living in it.

What completes the storm sewer:

Chute or tray. They are located on the ground or under it. Mounted at an angle to the drain. With the help of trays, water is directed to the drain and outside the site.
Rain inlet. It collects water from surfaces located above the ground - roofs and canopies. It is installed under the water drain pipes. They, like baskets, collect all the water in themselves and transport it to the right place.
Wells for inspection. Such a device is designed to determine the degree of contamination of the drain.
Trash catcher. Installed on top of drains to remove particles that clog the drain.

When installing a storm drain, you need to confirm the presence of downpipes and water drainage systems. A trench is dug at a certain angle. Its bottom is rammed and the pillow is filled up. In this case, the use of drainage is not excluded. A pit is dug to install a water collector, and a container or tank made of concrete is placed. Pipes are placed on the pillow, connected and sealed. The system is ready to go.

The garbage catcher is installed at the joints. And on the bends they install a viewing hatch.

The work is checked, and installation errors are detected experimentally. Everything is covered with soil and closed with bars. It is in this order that the water flow system in a private house is installed. Roofs must be connected by a single system of drains - this option is called a herringbone. If the sewer is installed correctly, then its use will be completely invisible to the owner, and slush and puddles will disappear from the site to the delight of loved ones.

Storm sewer device and technology

It is better to entrust the installation of stormwater to people with extensive experience in such work. But if you really have to install it yourself, you need to remember about the technology of the process. For example, when installing a drain, it is necessary to take into account the side on which the slope is made. It must be done in the direction of the water flow.

Things to consider:

In addition to the material, its location is also taken into account. For example, it is better to give up a lot of turns and corner placement.
The hermetic connection allows the entire system to be reliable protection from excess moisture. In the absence of tightness, water will seep into the ground or accumulate in the wrong places, which leads to the complete meaninglessness of the drain.
When sloping, the main rule is not to retain water. Keep in mind that water freezes quickly in winter. big swings temperatures provide it in large quantities, and frost freezes it. This further leads to clogging of the drain.
Before installation, the number of all elements is taken into account. Even debris protection elements are included.

Since the work takes place under the constant influence of moisture, then the material must be chosen resistant to this element - even and durable. It is better not to use corrugated pipes - they will become clogged more often than usual. If the water supply is long, then more wells should be installed to check for leaks or blockages. This is necessary for timely repair and cleaning.

Storm sewer system: care

There is no need to constantly call a specialist for cleaning and maintenance of stormwater. This can be done on your own. After heavy rains, it is necessary to clean the trays and gutters from sand and dirt. It is necessary to constantly clean the receivers of moisture and rain and follow the rules of operation. If water begins to accumulate and it seems that the system is not doing its job, then it is repaired.

Repair and replacement of fault:

The storm drain is opened and inspected;
Damaged items are replaced with new ones;
Testing the system;
Fall asleep with soil;

The work is carried out very quickly to avoid flooding the area with water, especially if the function of the sewer is to purify the water. An excellent help during the repair will be a water seal that helps to reset the water level. It is necessary to take into account the durability of the elements when working with water. Any material under its influence will deteriorate and rust.

Instead of rusty parts, new, plastic ones are installed.

Storm sewer device (video)

Considering beneficial features such a method of collecting excess water from the site, you do not notice its disadvantages at all. At correct operation and timely care, and repair, they will not interfere with life. Water will disappear from the site, as if it did not appear, and the reliability of the walls and foundation of the house will be under control. Moreover, when cleaning such a sewer, you don’t have to worry about the plants on the site - there will be no busting with moisture and decay, its location can be taken into account at the project stage, which will save the design and landscape. Using this system in a private home will forever relieve headaches in the spring and after the autumn rains. The house will stand securely, and the harvest will delight.

Stormwater examples (photo)

Water that accumulates during rain or from melting snow near the house can lead to flooding and destruction of the foundation. To prevent this from happening, storm sewers are required in a private house.

In addition, it is required for the accumulation of water resources in regions with an arid climate. And also to remove excess moisture from vegetation on adjoining territory. It can be easily installed by yourself.

Storm sewerage in a private house: device

Drainage is a system by which the collection and filtering of melt and rainwater accumulated in a special reservoir. Then they are used as process water.

Trays or storm water inlets are divided into:

closed type;
open;
combined type.

Open and closed storm sewers in a private house are considered part of the path. In the first case (simple point sewerage), water enters the tray from the roof through the drainpipe. In the second (closed) version, water enters the buried pipe, then into the collector to collect water. Closed trays are directly mounted in them, leaving only gratings on the surface. Through them, moisture goes into the underground pipeline. This type is used for large building perimeters.

For open storm sewers in a private house, external water inlets are used. They are open and mounted on the surface.

By design, they do not differ from closed ones, but they are flooded more often, so more care is needed. Apply such or a small cottage. There is also a third type storm system water disposal - mixed or combined. It combines the features of internal and external drainage. In it, one part of the storm drain is carried out by closed drains, the other by open drains.

Water disposal elements

Drainage and drainage pipes come from:

plastic;
concrete;
cast iron;
alloy steel;
aluminum.

For arranging storm sewers in a private house, do-it-yourself plastic and steel materials because they are reliable and easy to install.

The storm sewer system consists of:

gutters and storm water inlets;
collectors for collecting water.

Gutters and storm water inlets

This is the initial link in the system, through which wastewater enters the drain and pipeline. When choosing a material, preference should be given to concrete or plastic, since metal ones are very noisy under the blows of rain and gusts of wind, if not buried in the ground. In addition, they are prone to corrosion. Concrete is more reliable and has a long service life. However, such gutters have strictly regulated dimensions and it is not always possible to install them on the site. Plastic, on the other hand, is easily cut and combined, and the storm water inlet can have a different depth of the well. With an existing blind area, they can be easily mounted without dismantling it.

Filters

Designed to hold stones, leaves, sand, branches and other debris that can clog pipes. Lattices allow you to clean storm sewers less often, eliminate the risk of stumbling. Cast iron as a grating material is reliable, but requires painting every 2 years. Steel rusts quickly. aluminum can be considered the best option, since it has a long service life and looks stylish. However, it is somewhat more expensive.

The dimensions of the holes should not be very small, as they must pass a lot of water at once, but not large, otherwise debris will enter the system and lead to clogging.

Pipe networks

The pipes carry the flow to the water collection point. If they are made of PVC, then this perfect solution for storm sewers. Them smooth surface eliminates the risk of silting. Their diameter is 100-150 mm.

Collector for collecting water

The collector enters the closed and mixed system stormwater and is a reservoir for receiving the main flow of water. A similar well can be equipped with a sand and gravel cushion and concrete rings or a concrete ring with a bottom to use the liquid in the future. plastic well assembled from PVC molds. It is perfect for those areas where groundwater occurs superficially. Drainage occurs using a piping system, and moisture can also be used for economic purposes on the site.

Instead of a collector, it is permissible to make drainage from a special perforated plastic container with the discharge of water into the ground, placing it horizontally and deepening it into the sand. Through the holes, moisture will gradually seep into the sand and go into the depths.

In addition, the stormwater device can be supplemented with an under-door tray installed near the porch when front door, pipes for soil drainage, a hatch for access to the system.

Operating principle

The main principle of the sewerage system is the observance of gravity, for which it is necessary to take into account the following factors:

The location of the building to determine the length of the storm pipes around the house.
Relief features of the area.
Climate and rainfall to determine the volume and number of wells and pipes.

With an average annual rainfall of 60-90 cubic meters. m pipe diameter should be 11-12 cm.

The scheme of installation of storm trays in the courtyard of the house depends on the type of rainfall collection. It can be linear or dotted.

The layout of the system should be considered when designing a house so that drains are discharged in a straight line and there is less problems with cleaning.

The diagram indicates the location of communications, storage, equipment and drain circuits. When combining drainage and storm water into the sewer, a more serious approach will be required and a geodetic study of the territory will be required in order to identify the level ground water. This will make it possible to determine the most comfortable spot for storage and drainage.

Mounting

Before installation, the territory is marked out in order to determine the location of the trenches. If turns are necessary, then they must be made at a right angle and inspection hatches should be made in these places.

The device of ground channels, trays and gutters should be carried out in open areas of the site. When installing the tray, the soil around it should be tamped to prevent subsidence of the soil.

Pipes are laid with a slope of 1 cm per 1 m of length.

They are best used from PVC, since the material is not subject to corrosion. Pipes are laid in a trench, into which crushed stone and sand are first poured, geotextiles are spread.

Then the pipe is completely wrapped with geomaterial and the trench is covered with excavated soil.

Connections are made with couplings of suitable size and type.

Finally install the receiver.

Installation is carried out with a slope towards the drive.

If the elements of the system pass under functional areas(entrance, parking lot), then additional reinforcement in the form of an overlap with further backfilling will be required.

cleaning function

A storm water drainage system, unlike a septic tank, does not need deep cleaning. Water in this case can be drained into the ground, the nearest stream, ravine or used for irrigation.

At the same time, without violating sanitary and hygienic standards and soil ecology. But basic filtration is necessary, for which sand traps are used that trap various debris, stones, leaves, and so on. Also, the pipes are periodically washed with the pressure of the jet using a pump. The flow can eliminate pollution in hard-to-reach places. The drive is cleaned separately using disinfectants.

The construction market offers all sorts of options storm sewers, so you can use any configuration. The most reliable is considered a trench system using trays, wells, a collector, and filter membranes. But it is intended for a large area, for small area an open storm drain around the perimeter of the house is suitable. The drain can be connected to sewer septic tank with multistage biological treatment Wastewater.

Only rain and melt water no need for fine filtration. For them, it is enough to equip the system with gratings and filters, but they must be cleaned mechanically, otherwise the channels may become clogged, causing flooding of the territory.

Unusual do-it-yourself storm sewer - video

There is not a single private house that would not be exposed to atmospheric precipitation. After good rain a lot of moisture remains on the surface. It is especially difficult for those whose soil contains clay. The soil is constantly sour, there are a lot of puddles and dirt in the yard. This does not make the site attractive. To get rid of this problem, you will have to arrange storm sewers. It can be done with your own hands at the construction stage. country house.

But if your house is already standing, it doesn’t matter, a storm sewer system can be mounted around the house without any problems. We will talk about this in more detail in the article.

Protection from atmospheric precipitation due to storm sewers

We live in an area where there are no areas with no rainfall. We face them all year round, in the form of rain or snow. Such high humidity harms not only the building, but also your growing crops. Still water won't give them useful substances. And if there is also a cellar or basement in the country house, then the liquid can flood them without problems during a heavy downpour. How to get out of the situation?

Around the house you need to make a storm sewer. It serves to divert excess water to the right place or outside the building. In addition, if the structure is correctly mounted, it will not only collect liquid, but also clean it of sand and other impurities. At the outlet, the water is clean and does not harm the environment.

Components of the construction of storm sewers

Before proceeding with the installation of the system, it is important to find out the storm sewer device in a private house. Only then can everything be done correctly so that the sewerage system lasts a long time. All components of the storm sewer form single system. Let's take a look at these elements.

Well

This is a special tank in which all waste water. It is important that it be large - the bigger the better. However, consider the amount of rainfall in your area. If it is small, then an average well is enough. The size of the roof slope and the size of the plot also affect the choice. The well can be made of concrete rings or plastic. The tank must have a bottom. This is the heart of the storm sewer.

Hatch over the well

You can choose a ring and a separate plastic, metal or rubber hatch. Then the well is dug in so that the cover is placed 15-20 cm lower than the ground level. To install the hatch, you will need to fill in or lay out the neck from the brick. But the result will please, because you will not see any differences on the lawn. When using a finished cover with a hatch, the soil is poured 4-5 cm. Then the lawn will be slightly different.

Drainage channels (storm water inlets)

This is one of the types of drainage channel. They look like gutters protected by bars. They are made of plastic, metal, composite or reinforced concrete. They are installed in places where the amount of precipitation is greatest, namely: along the paths for pedestrians and along the roof slopes. They are installed in the case when, when making a blind area, they did not lay pipes for draining. So you wash not to destroy the blind area.

Point storm water inlets

This is the second type of drainage channel. These are smaller containers that are installed in places where liquid accumulates: under drainpipes and in places with a low point. The body can be made of concrete or plastic. Usage concrete structures rational in the construction of deep storm sewers. Rain inlets are stacked on top of each other to the desired height.

Note! already exist plastic products which can be adjusted to the desired height.

Sand catchers

it special devices designed to filter sand, it settles in them. Most often they use a plastic case, cheap and cheerful. They are mounted at a distance on long pipeline sections. All heavy inclusions remain in them without passing further through the system. They need to be cleaned from time to time.

Protective grilles

They prevent leaves, branches and other debris from entering the drain. To prevent water from lingering, it is better to take medium holes. Lattices can be cast iron, steel and aluminum alloys. Last option the most profitable, since steel products quickly rust, and cast iron is brittle with temperature changes.

Pipes

These are the "veins" of storm sewers. It is through them that water moves. The ideal option considered pipes made of polyethylene for external use. They are red in color. Due to the smooth walls, precipitation will not accumulate in them. In addition, their conductive capacity is significantly higher than that of other pipes of the same diameter. Sometimes used cast iron pipes and asbestos. The diameter of the pipes depends on the amount of precipitation. Minimum- 150 mm. The bigger, the better. Pipes are placed with a slope to the storm water inlet of 30 mm per 1 m (3%), and then towards the tank.

An important part that allows you to clean and maintain the pipeline. Is it a plastic or concrete well small size, which is installed in some sections of the pipeline where the system branches.

Here are all the components of a storm sewer for a country house. Thanks to her, your site will be dry and attractive.

What is storm sewer

Depending on the elements, storm sewers can be divided into several types:

Linear storm sewer.
Point storm sewer.
Mixed storm sewer.

As you already understood, we are talking about storm water inlets. The type of system depends on their choice. It differs both in device and purpose.

Linear storm sewer system

It is also called the system open type. It is quite simple to make, and there is no doubt about its effectiveness. Such a system consists of a network of gutters, materials known to us. It is recommended to use either composite or plastic gutters. The price-quality ratio justifies itself. Water enters the canals from downpipes or paths, after which it is directed to a well or a common sewer system. From above everything is covered with a grate to protect against debris. In addition, the lattice serves as a decorative element.

Docking of individual gutters with each other is carried out using a sealant so that water does not penetrate into the connecting joints. If you want to make your site drier and more beautiful, then this a good option. The system has a large coverage, as it can collect water from the sidewalk, walkway, other areas and roof drains. In the photo you can see an example of a linear type storm.

Note! When installing the system, it is necessary to make a slope of each gutter so that water does not accumulate in it.

Point storm sewer system

It is also called a closed system. It got its name because the entire pipeline system is underground. The process of work is as follows: water, flowing down from roofs and other surfaces, enters point storm water inlets with gratings, and then moves through the pipe system into a sewer or a well. What the system looks like, you can see in this photo.

Note! The installation of underground communications is a complicated matter, therefore, it is necessary to equip the system only at the stage of developing a building project. Then it will be almost impossible to make it.

Mixed storm sewer system

This type of system is used to save personal money and effort. It is clear that the device open system it will take less time, effort and money than a closed storm drain. A mixed sewer is something in between. It includes elements of both types.
