Storm drain in a private house. Do-it-yourself storm drainage Storm drainage location

Your favorite shoes are probably well familiar with the delights of a poorly functioning city storm drain. Often, after a “dense” meeting with deep puddles accumulated on the asphalt, beloved shoes and boots leave only pleasant memories and photographs. For a city dweller, the loss of shoes is the maximum damage, to the owner country house the damage is more widespread. To ensure that atmospheric water does not slowly but persistently destroy the foundation, does not flood basements, and does not contribute to the rotting of the root system of plants on the site, water drainage is required. A not-too-complicated do-it-yourself storm drain can easily be organized by a contractor who has nothing to do with construction specialties.

Purpose and specifics of the storm drainage device

Storm sewerage is a complex of devices and channels that collect, filter and drain atmospheric moisture into filtration fields, special reservoirs, and reservoirs. Its task is to eliminate excess moisture, which creates discomfort, destroys structures and reduces life cycle plants.

The storm drain is a linear network that includes such standard elements as:

storm water inlets, represented by funnels, pallets, linear trays that collect water;
gutters, pipes, trays transporting water to sand traps - filtration devices, and further to collectors, ditches, reservoirs, and unloading fields;
inspection wells required for monitoring storm system;

filters, sand traps that retain soil particles, plant fibers and debris, protecting the network from contamination.

Storm drainage is a complex of channels and devices that collect excess atmospheric moisture, filter it and discharge it first into a collector well, then to unloading points

Options for rainwater inlets for storm drainage: on the left there is a door pan, in the middle there is a funnel receiving water from the drain, on the right there is a gutter with a sand catcher

All elements are combined into an integral system operating using linear or point technology. If channels storm sewer laid in the ground, pipes are used for their construction. In surface ditches, gutters and trays made of plastic, asbestos or concrete are installed.

Important. To ensure the natural movement of rain and melt water to the places of filtration and unloading, pipes, trays, gutters are laid with a slope towards the drainage devices and unloading places.

Classification according to wastewater collection method

Depending on the collection principle according to which the storm drainage system is installed, all existing storm drains are divided into two types.

technical specifications

Point type of storm drain: a storm inlet is installed under a drain; the funnel receiving water is equipped with a mesh for filtration and an internal basket for collecting debris

open method

A linear storm drainage diagram can cover large territory, drain drains not only from the roof, but also from landscaped areas, from sidewalks, and from those sides of the house where, due to the specifics of the pitched structure, there are no drains

Based on design differences and extent of territory coverage, the type of system is selected. However, these are not fundamental selection criteria. Basically, storm sewerage in a dacha is arranged according to the experience available in a particular area in the organization and operation of storm sewer systems. Based on it, the type of channel laying and their depth are determined.

Preliminary calculations and design

Implementation of plans without calculations is money down the drain. If the system does not cope with the function assigned to it by the owner, there is no point in undertaking its construction at all, and a storm sewer system that is too powerful for a private house will “eat up” a lot of financial resources.

Video: design and installation rules

Information required for calculations

Data on the average amount of precipitation recorded by meteorologists in a specific area. You can find them in SNiP 2.04.03-85.
The frequency of rains, the thickness of the snow cover, necessary for those who plan to use the system and for draining melt water.
Drain area. For the point variety, this is the roof area. Moreover, not the full value, but the value of its projection in the plane. For linear system The drainage area will be the sum of the areas of all processed objects.
Physical and mechanical characteristics of soils available on the site.
The presence and location of existing underground communications already on the site.

Calculation of the volume of discharged wastewater

The above exact values of the amount and intensity of precipitation are the result of many years of research into physical phenomena in the atmosphere of a given area. They can be found in SNiP or obtained from the local weather service. Further calculations are made using the formula.

Formula for calculating atmospheric water flow, as well as constants and variables used in calculations

The correction factor used in this formula is:

0.4 for areas covered with crushed stone;
0.85 for concreted areas;
0.95 for asphalt areas and paths;
1.0 for roofs.

We obtained the volume value, then the required pipeline diameter is determined using the tables of the current SNiP.

Channel laying depth

Trays or channels made of pipes must be laid at the depth at which they are usually laid in a given region. The exact value can be found in construction organization or ask your neighbors who have already equipped their area with a storm drain. IN middle lane The rainwater drainage system is usually installed at a depth of 0.3 meters, if the diameter of the pipeline or open trays is not more than 50 cm. Trays and pipes with larger dimensions are buried by 0.7 m.

Important point. If the site has a drainage system, storm drainage is laid above the drainage.

If a drainage system is already installed on the territory, the storm drain is located higher

Expensive earthworks usually does not stimulate the desire of customers of professional installation to go very deep into the ground. Even if you decide to install a storm drain yourself, there is no point in burying it too deeply. There is no reason to install collectors and inspection wells below the seasonal freezing level, as GOSTs dictate. They can be placed higher, insulated thermal insulation material- geotextile and a layer of crushed stone that protects the network from freezing. Due to the slight depth, the labor intensity of the work is significantly reduced.

Insulation of storm sewers in case of slight deepening is carried out from a layer of geotextile and a layer of crushed stone; thanks to the protection of the channels from freezing, you can significantly save on excavation work

However, we must not forget that the channels to the collection and cleaning devices must be directed at an angle. This means that the level of the entry point into the collector well must be lower than the level of the tray or pipe extending from the storm inlet. To accurately calculate the depth of their installation, you need to draw a site plan and, taking into account the slope of the channels, calculate everything.

Scheme of a storm drain, the channels of which are laid below the freezing depth; insulating geotextiles protect in this case from aggression groundwater

Standards and norms of slopes

regulated by GOST minimum slope for pipes with a 150 mm diameter 0.008 (slope value in mm/m). Pipes with a cross-section of 200 mm are laid at an angle of 0.007. Depending on site conditions, pipe slopes may vary slightly. The largest slope is 0.02 in the area where the canal joins the storm water inlet, since in this place it is necessary to increase the speed of water gravity. In front of the sand traps, the flow velocity must slow down so that suspended particles can “settle”; the angle of inclination is the smallest there.

Devices for collecting water in envelope-type systems with rainwater inlets-funnels are installed at the intersection points of slopes.

The process and specifics of storm drain installation

Rules installation work the design of storm drains is identical to the principles of laying conventional external sewer pipelines. However, if the house is not equipped with gutters, you need to start by installing them.

The rules for installing a storm drainage system are similar to the rules for installing conventional sewerage

Construction of the roofing component

You need to make holes in the floors of the house for rainwater inlets. After installing the devices and securing them to bitumen mastic The junction points must be sealed.
Sewage pipes and risers are installed.
All elements must be attached to the house structures using clamps.

Scheme of the roofing part of the storm drain: 1. gutter; 2. external corner of the gutter; 3. inner corner of the gutter; 4. gutter plug; 5. gutter connector; 6. hook; 7. hook; 8. funnel; 9. drainage funnel; 10. pipe elbow; 11. drain pipe; 12. connecting pipe; 13. pipe bracket (on brick); 14. pipe bracket (on wood); 15. drain elbow; 16. pipe tee

Construction of the underground part

According to the planned plan, drawn up taking into account the slopes and the depth of canals accepted in the given region, it is necessary to dig a trench. If you plan to insulate the pipeline by forming a shell of geotextile and crushed stone around it, or installing a cushion of sand, their power should also be taken into account. Here's how we proceed:

The bottom of the trench is thoroughly compacted before installation. Large stones encountered during digging are removed, and the holes formed after their removal are filled with soil.
A sand cushion is poured onto the bottom, standard thickness its 20 cm.
A pit is being formed to install a collector tank. The easiest way to use a collector is to use a ready-made plastic container, but if you wish, you can make a collector well yourself by pouring concrete into pre-arranged formwork.

Pipes are laid in compacted ditches equipped with sand cushions, and fittings are used to connect them into a single system.

Connections of underground drainage channels are made using fittings

It is recommended to include inspection wells in straight storm drain branches longer than 10 m.
Sand traps must be installed at the junction points between the collectors receiving atmospheric water and the pipeline.
All devices and fixtures are connected into one circuit, the connection points of the components are sealed.

Before filling the trench, it is necessary to carry out tests by pouring water into the water intakes. As a result of testing, no weaknesses were found? We fill the system laid in the trench with soil, and equip the gutters, trays, and pallets with gratings.

Before backfilling the trench, the constructed system must be checked, all defects and leaks should be identified and eliminated if they occur.

Advice. Pitched roof structures are not equipped with gutters on all sides. Where they are not available, it is recommended to install gutters with gratings and connect them to the general network.

The city collector well is prohibited from being discharged into the general sewer network due to the presence of chemicals and petroleum products in the wastewater. The owner of a country house can freely connect a storm drain to his own sewer system, because it contains no dangerous components that require fine cleaning.

After cleaning in the sand trap, the water enters the sewer, from where it can be distributed directly into the ground, discharged into reservoirs or into the regular sewer network of a private home.

Improving the house and surrounding area with a surface drainage system will help extend the life of structures, relieve the owners from puddles and slush, and prevent rotting of plant roots. A simple do-it-yourself storm drainage system can be installed by the owner himself, but even if you turn to builders, information about the specifics of its organization will not hurt. The owner himself will be able to monitor violations, repair and clean them.

Rainwater sometimes it turns out to be very valuable natural resource to scatter it left and right. Therefore, modern storm sewers are becoming more and more complex, and are often equipped with special elements designed not only to minimize negative consequences rainfall, but also for efficient water collection.

Classic storm drainage device

The basis of storm sewerage is the system of direction and distribution of water. In a simplified version, storm drainage includes the following elements:

Pipe. Most often it is laid in the ground and covered with a layer of turf, concrete or a hard surface of asphalt and paving slabs;
Drainage channels or trays. Most important element storm sewer, from correct location water collector depends effective removal water from the surface of the walkway or area near the front door;
Filtering and distribution elements. Their participation in the operation of storm drains is invisible, and most people are not even aware of their existence, but they are extremely important for normal operation the entire system.

Important! Storm drainage not only and not so much helps to effectively drain water, but above all, it protects the soil and foundation from oversaturation with water.

Basic elements of storm drainage

All elements of storm drainage are equally important for the effective removal of water from the surface of the site. Failure or abnormal operation of any of the above elements may reduce throughput sewer system to a minimum.

Device for receiving storm water flows

Stormwater inlets or, more correctly, water inlets and trays for storm drainage, gutters that serve to collect water flows on the surface of the earth, are the most vulnerable to mechanical impact from feet, wheels, Vehicle, even icicles and freezing ice. Water receivers are most often made in the form of a rectangular or cylindrical box made of plastic or fiberglass reinforcement.

They are installed directly below the drainage hole of the downspout and serve to receive the flow of rainwater collected by the gutter system. The inlet opening is always covered with a metal or fiberglass grill. There is a hole in the side wall where the drain pipeline is connected. Some water intake designs provide additional element for filtering large pieces of debris, tree branches, wood chips, small pebbles. This element does not retain sand and small particles of dirt well. Often even experts are confused and believe that this is a sand trap for storm drainage.

Storm water inlets for storm sewers must ensure shock-free intake of water flows without splashing, even if part of the receiving device is covered with leaves or pieces of ice. The condition of part of the foundation and wall of the house depends on the efficiency of this element of the storm drainage system.

In addition to water intakes, rainwater drainage trays, or gutters, collect water. Most often they are installed along paved walkways. Paved areas and paths are especially sensitive to excess water. paving slabs. Incorrect or ineffective work leads to swelling of the masonry due to frozen water in the sand cushion.

Storm drainage trays are long plastic gutters laid directly on a sand bed in the ground and covered on top with a protective cover with holes. Required condition When laying trays, it is necessary to maintain a drain slope in the direction of the receiving pipe. In some cases, storm drainage gutters stop working effectively if people step on the installed gutters or vehicles run over them. To avoid this, a stone or tile border is laid on the sides of the tray.

The cover can be plastic or lattice, but the latter option is used less frequently due to its poor ability to trap large debris and dirt entering the sewer system.

In addition to tray systems, point-type inlets are also used in rainwater collection systems. These elements are designed to collect rainwater in a certain area where it is impossible to install gutters or trays. Most often, this is a concreted area, on the surface of which there are slopes and a grid of profiled grooves for water drainage.

A separate element in rainwater collection systems is a receiving box or tray installed directly in front of the front door to the house. Such a device is used to catch rain and storm water that enters the entrance area of the porch. The design of the pan corresponds to the structure of the rain inlet, but differs in size.

Prefabricated, distribution and filter elements

All drainage elements of rainwater collection systems direct flows through pipes to places where it is collected, settled, filtered and, if necessary, discharged into the central storm drain. The use of polyvinyl chloride or polypropylene is considered standard today. corrugated pipe. The diameter of the pipeline, depending on the load, can range from 100 to 200 mm. This version of the pipe is highly flexible, resistant to frost, clogging, and can easily withstand any subsidence or soil movement without destruction.

In addition to polymer pipes, asbestos-cement pipes are used. They are highly resistant, but their use is currently limited due to the presence of asbestos fibers in their material. Cast iron, steel, and ceramic pipes are practically not used due to their high price.

Required element modern systems Rainwater collection is considered to be a sand trap, which frees water from the smallest particles of sand, dust and dirt. Essentially, this design is a large container in which rainwater settles and is separated into sediment and clean water. The design provides the ability to remove sediment and contaminants. Less commonly used are vortex sand traps, in which grains of sand and tiny gravel are separated from the storm flow as they pass through an annular chamber.

In some cases, in addition to the sand trap, a filter can be installed to separate petroleum products, oils, and heavy organic substances that are insoluble in water. Typically, such elements are a mandatory attribute of storm drains at gas stations, parking lots, auto repair shops, and are used quite rarely for domestic purposes.

The most expensive and largest element of rainwater collection systems is the distribution well. This device is a barrel-shaped container to which pipelines from water collection devices in a certain area are connected. Depending on the size of the plot, 2-3 distribution wells can be installed in one household. This element is buried in the ground so that the water column in the container is at a level lower than the pipelines connected to it. In this case, the collected water will not flow from the well back into the storm drain.

One of the essential communications in a private house is storm drainage. It is needed to drain rainwater away from the foundation, paths and plantings that are sensitive to waterlogging. This not only protects property, but also adds comfort to the homeowner.

The problem of spring snow melting is almost completely solved by snow removal, however, even in this case, storm water will be useful, because no one knows how punctual your neighbor is in this regard.

Design features

Depending on the size and characteristics of the site, the complexity of the design can vary from elementary to very complex engineering structure, but any stormwater system consists of three main elements:

Water inlets on the roof and ground into which water flows from nearby surfaces.
Pipes and channels through which water flows to specially designated places.
Collectors or reservoirs where water is collected with the possibility of recycling or disposal to third-party drainage systems.

At the design stage, a number of factors should be taken into account that will determine the type, method of laying drainage systems, material of manufacture and other parameters of the storm drainage system.

In particular, the area of hard surfaces, soil structure, relief and other indicators are important.

Dot diagram

With this approach, water is collected at specific points and involves removal through underground pipes. Suitable for areas with big amount surfaces with low water permeability - concrete, asphalt, hard soil.

Also called rain or storm drain. It is installed on the site to collect and drain water from the roofs of houses, road surfaces and land plots. Storm drainage should not be confused with ground drainage, which is laid to a certain depth and is designed to reduce the groundwater level. It is relevant for areas in lowlands, for areas where significant amounts of precipitation fall.

Storm drainage is also used in flood areas. If there is a lot of water in the area, it can cause flooding. Over time, the foundation erodes, the soil becomes waterlogged, and the basement floods. protects the site and the house from such troubles.

What is a storm drain

The rainwater drainage system consists of pipes, trays, plugs, sand traps, storm water inlets, siphons and other elements. The system can also be supplemented with a storm well. The final scheme will depend on the type of stormwater. The main purpose is to collect surface water and directing it to the sewer.

The moisture collects in a single stream. Water drainage from the system cannot be done into the soil drainage system. They are installed parallel at the same angle, but are different designs. Storm drainage is done above the ground drainage.

Stormwater scheme

Storm sewer treatment systems are installed under drainage systems vertical pipes. There should be several water reservoirs on the territory. All of them are tied with polymer. This allows you to connect the elements into a single system.

The scheme also provides for a prefabricated well, which is usually located in the lowest place on the site. Therefore, the stormwater system uses the principle of gravity flow. The drainage scheme may involve the use of pipes that are installed in a herringbone pattern or in a circle.

In the first case, a straight line is drawn from the water collectors near the house to the well. Contours from parts of the site are connected to it and outbuildings. In a circular diagram there is a main circuit, but additional ones are connected in a circle. A system of sewer pipes is laid around the main house, which are complemented by contours. If the area is large enough, then there may be several circular contours.

How does a storm drain work depending on the method of drainage of precipitation?

A storm sewer system can be classified by the method of drainage. It can be open and is also called superficial. Rainwater is drained by this system using open gutters in the form of trays and channels. Moisture leaves the area. Trays can be recessed, installed in paths, as well as blind areas. They are sometimes fixed cement mortar. Sewer grates are installed on top of the gutters, which are removable.

The open system is most common in private homes, as well as small settlements with low population density. The storm sewer system can also be closed, it is called deep. Water in in this case collected in built-in trays and sand traps. Moisture enters storm water inlets, which are wells. Along an inclined line, precipitation is directed into the sewer network. Pumping equipment can also be used to transport water.

Rain and melt water pass through the sewer, thalwegs and end up in wastewater treatment plants and artificial reservoirs. Closed system used in large populated areas and cities, sometimes on private territories.

Mixed storm drainage device

Mixed storm sewer is a drainage system that consists of street gutters and underground pipes. In the design, wastewater is drained by gravity. The only exceptions are unfavourable conditions relief.

The route of the storm network is located along the shortest path to the point of discharge into the reservoir or sewer. The construction uses reinforced concrete. Mixed storm drainage is suitable for reducing construction costs.

Classification of drainage by type of drainage

Point storm drainage is provided using local drainage systems in the form of stormwater inlets. They are installed to collect water from a point area, for example, from a roof. The drainage and storm sewer system of the workers' village has gratings and filter baskets, the latter of which are necessary for retaining waste.

The system is connected to underground sewer pipes, which transport water to a collection well. Storm drainage can also be linear. It is installed to collect atmospheric precipitation from an impressive area.

Linear drainage is designed to solve drainage problems in a comprehensive manner. This system is based on:

channels;
trays;
gutters;
sand traps.

The latter are containers for retaining small debris and sand. There is a basket inside where garbage accumulates. Cleaning of such sewers is carried out by emptying baskets.

Storm water system with drainage

If the stormwater system is supplemented by drainage, then the latter can be equipped using closed technology. The pipes are located underground, and only the well covers are visible on the surface. Underground drainage can be installed in areas with clay soil and with soils where loams predominate. Drainage is also relevant in areas where the aquifer lies high. Drainage is required if there is water in the basement in the spring, or if the foundation had to be deeply deepened.

When considering the installation of a storm sewer with a drainage system, you should note that the latter provides for the presence of:

inspection wells;
drainage mains;
sand traps;
drain;
storage and transfer wells.

Collected from the soil excess moisture, and sand traps clean it of silt. Excess water flows into the reservoirs thanks to the main pipeline. This process is controlled by wells, the design of which can be different. They also help clean the system.

Drains can be made of the following materials:

ceramics;
asbestos cement;
plastic.

Asbestos-cement pipes are quite cheap, but are inferior to others in durability. Ceramic ones are ready to last for decades, but are more expensive. More popular are plastic pipelines, which can be based on polyethylene, polypropylene or PVC. Polyethylene products are the most frost-resistant; they do not crack during sudden temperature changes.

The roof storm drainage system is an integral part of the scheme. Its elements are installed along the walls on the roof. Using trays, water is collected from the roof and transported to the ground storm drain. The drainage system includes:

funnels;
connectors;
drainage gutters;
stubs;
tees;
swivel knees.

Modern drainage system is a construction set whose parts are assembled in a certain sequence. Elements can be made from the following materials:

plastic;
ceramics;
galvanizing;
copper.

The choice will depend on the architecture of the house and the type roofing material. Gutters are sometimes supplemented with protective nets, drips and anti-icing cables. These devices are not mandatory, but they can improve the functionality of the storm drain.

Storm drainage systems for a private house provide for inspection and drainage wells, which can be made of:

plastic;
stone;
bricks;
reinforced concrete rings;
car tires;
fiberglass.

The materials may be different, but the design is the same. It assumes the presence of a lid, a shaft, a working chamber and a bottom. Ready-made well structures are easier to install than others. This is especially true in the case of plastic. The most budget-friendly option is made from reinforced concrete rings or car tires.

Gutter "Geberit"

When it comes time to add a gutter system to your home's roof, you may want to consider several options. Among others is the Geberit storm drain, which has increased throughput and a reduced pipe diameter. The siphon storm drainage system has been setting the standard for indoor drainage for several decades.

The funnel design ensures that in the event of rain, risers and pipes will fill without air pockets. The Geberit storm drainage system has pipes into which water flows, forming a closed column. It creates low pressure and sucks in wastewater. This increases flow rate and capacity despite the reduced pipe diameter.

Freedom of design and reduced labor costs with the Geberit rain shower

Geberit provides consumers with maximum design freedom, as designers require fewer rainwater outlets, sewer pipes and risers. When laying supply pipelines, it will be possible to ensure reduced pressure, so slopes will no longer be required, which simplifies installation and saves space.

The Geberit storm drainage system reduces material costs and reduces labor costs. To plan the system, you can use a program with the Pluvia module. As a service, the company offers consumers to perform calculations for internal drainage systems.

Stormwater sampling

The sampling technique for the storm sewer system provides that it is located before the discharge of treated water. The unit is equipped with a butterfly valve and is designed for sampling the treated wastewater. The well can be made of reinforced fiberglass and must have high chemical and corrosion resistance. An excellent example is the UNILOS-KK well, which has durability, low operating costs and low thermal conductivity.

Wells are located along the route of wastewater after it passes through filtration systems. Sampling locations, also called control points, are selected in accordance with the objectives of the work. Samples must be taken from mixed flows. Collection sites should be close to the discharge point.

Sample classification

For lowering, transporting and lifting the sample, if necessary, means of mechanization should be provided, for example, carts and winches. There are simple and mixed samples. The first characterize the composition of water and are obtained by a single selection. A mixed sample characterizes the composition of a liquid over a certain period of time.

Storm drains are regularly inspected and cleaned. Inspections are carried out in the spring and late autumn in preparation for winter. The entire system is inspected after every heavy rainfall. Even if the design includes nets on water inlets and sand traps, suspended silt and small debris can get inside the sewer.

The list of works for the maintenance of the storm sewer system includes the removal of foreign elements from gutters, pipes and wells. This must be done during regular checks, otherwise the drainage elements will become silted, which will lead to the cessation of operation of the storm drain.

Carrying out cleaning

Pipe cleaning is carried out with a pump and a large volume of water. Using a hose with a nozzle, you can wash away all deposits from the walls of the pipelines. Limescale and the sludge will end up in a well, from which the garbage is pumped out by a drainage pump or a vacuum suction pump. Usually flushing is enough, but sometimes you have to resort to mechanical cleaning using scrapers or a plumbing cable with a hook.

Finally

Every home must have a storm drain. It consists of plastic sewer pipes, fittings and a prefabricated well. The scheme also provides for the presence of collections in the form of cones. We should not forget about decorative grilles, with the help of which the water collectors are decorated and the system is protected from penetration and debris.

Strives to the best of nature embedded in everyone. We want to walk on clean sidewalks, walk in parks and alleys without puddles, and, of course, have a beautiful and well-groomed area near our house. All this requires a new, European approach to the development of the territory. The leading role in this issue is played by high-quality and modern drainage systems and rainwater drainage.

Storm drain(also known as storm drain or storm drain) - it's complicated engineering system, designed to organize the drainage of rain and melt water outside urban areas or areas. Simply put, rain and melt water are discharged through storm sewer networks with discharges into collectors, reservoirs or roadside ditches. Drainage sewers are developed to collect and drain groundwater. Typically, drainage and storm sewers are laid parallel and at the same angle.

Modern system storm sewer consists of a number of interrelated and complementary elements and includes:

storm gutters (channels, gutters);
sand traps;
storm water inlets (storm water wells);
sewer pipes;
collector;
inspection wells.

Storm drainage must be designed as an integrated system utility networks and the organization of complete and rapid drainage directly depends on the quality of its design surface runoff. The most polluted storm drains (generated at gas stations, industrial enterprises etc.) must be cleaned.

When developing stormwater system projects, many factors are taken into account:

analysis of the balance of water consumption and disposal Wastewater;
rainwater flow rates (intensity and amount of precipitation);
drainage area;
the estimated duration of rainwater flow over the surface and pipes to the design cross-section;
terrain and many other circumstances.

The optimal option should be determined by the lowest value of the reduced costs, taking into account the reduction of labor costs, consumption of material resources, electricity and fuel, as well as based on sanitary, hygienic and economic requirements.

To reduce the length of rainwater drainage pipelines, maximum use is made of the possibility of draining water through drainage trays. The surface drainage system is really effective, and most importantly, economical.

At surface system Drainage trays for storm drainage are installed along the outermost strip of the roadway of the street or sidewalk, building entrances, and on the upland side of green areas.

In low places, at intersections, near buildings under drainpipes, point drainage basins are located - storm water inlets. Through pipes, storm water inlets are connected to storm sewers. It is also possible to connect drainage pipelines to the storm water inlet.

To prevent siltation of the trays, sand traps (at least 2) are built into the storm sewer system.

In places where channels are connected to a closed network, rainwater wells with a settling part are built in.

With modern, structurally thought-out materials from Standardpark, the construction and maintenance of storm drains is greatly simplified. External structures are incomparably easier to clean or replace.

The Standardpark company offers trays (channels), storm water inlets and protective gratings made from materials that are resistant to changing temperatures, exposure to air, microorganisms, moisture, weak acids and alkalis, and have sufficient mechanical strength.

Also in our assortment you will find a special rainwater curb. It is used on the highway, highways and sidewalks as a replacement for DB type drainage wells. A special feature of the rainwater curb is that it combines the functions of 3 elements road construction: hatch, curb and rain grate.

The products of the Standardpark company meet all the engineering and technical conditions of a high-quality drainage sewer system, without sediment accumulation, erosion of the channel cross-section, and are also simple and easy to use when cleaning and repairing channels.

The use of surface drainage systems from the Standardpark company contributes to:

reducing costs for storm sewerage;
release of excess water, resulting in no deterioration road surface and its service life is extended;
prevents foundations, blind areas from getting wet, and soil erosion;
prevents the accumulation of rain and melt water in puddles, which improves the aesthetic appearance of the areas.
