Storm drain cleaning. Storm sewer cleaning: what and how to do Storm sewer flushing technology

Storm sewers can be called the most important element that is used in the improvement of not only the capital, but also any other settlement. It is needed in order to immediately remove excess water from the site when the snow melts and when it rains. But an annual cleaning storm sewer because it can get clogged over time.

Causes of blockages in storm drains

It is known that storm sewers consist of pipes, trays and wells. Trees grow on the streets of Moscow, from which leaves fall. In heavy rain, they enter the sewer through the grates. And this applies not only to leaves, but also to other debris: sand, pebbles and even branches. In the sewer system, all this will definitely get stuck somewhere and a blockage will form.

When a storm sewer cleaning service is needed, the price of the work depends on how dirty it is, as well as what kind of pipeline is used there. It will be very difficult to get rid of the blockage that has appeared on your own. It is quite possible that at first you will have to use video diagnostics of the sewer system. After all, if branches got there, very serious equipment will be needed to remove them. In this case, cleaning the storm sewer will cost the customer more.

The main methods of cleaning storm sewers

Experts recommend cleaning such sewers twice a year. In any case, this should be done in the spring, when the snow melts. With melt water, a lot of garbage will fall into the sewer. You need to get rid of it as soon as possible. Otherwise, with the first heavy rain, a blockage will form.

Line cleaning methods are different. The most expensive is the hydrodynamic cleaning of storm sewers, prices for it can be found in the ZasoroLiquidator company. But such professional methods are also used:

- mechanical, when the blockage is simply punched;
thermal, where highly heated water or steam is used;
chemical, using certain reagents.

Often hydrodynamic method of cleaning storm sewers used in conjunction with mechanical After all, the blockage must first be broken through, and then wash off all the accumulated debris. The nozzle on the edge of the flexible hose will not always cope with a serious blockage if there are branches and pebbles in addition to leaves. It should be borne in mind that storm sewers can be both open and closed. If she open type blockage can be removed mechanically. For sewerage of a closed type, you only need hydrodynamic washing. So, you can’t do without the services of the ZasoroLiquidator company.

Storm sewer takes part in the improvement of the site. It is used to collect water after rain and snow melt and bring it outside the boundaries of the site.

However, over time, any debris can collect in the pipes of this communication - leaves that have got there that have begun to rot, small twigs, as well as sand or stones - due to them, various degrees of blockage can form. As a result, the capacity of the sewer pipe drops, and water does not flow through it, but instead collects in the yard. As a result, there is an urgent need to clean the system.

One option for cleaning storm drains is to contact a company that provides similar services. However, this option may not be affordable for everyone, especially if the pipe becomes clogged with debris several times a year.

Signs of clogging

In addition to debris clogging, clogging can occur from oil products and any suspended solids getting into the storm drain. Sometimes it can get to the point that the entire system is completely flooded with silt and dirt, then it will have to be dug out with a shovel. This is due to an oversight by the owners (or personnel who maintain the surrounding area) or extremely heavy rains that bring dirt from the higher ground.

Note! To avoid landslides, it is necessary to build a solid threshold under the fence or in front of it, and next to it, think over another drain communication so that the yard and local storm water do not clog with dirt.

The complexity of cleaning directly depends on the diameter of the laid pipes that make up the storm sewer. Depending on this, it is also determined what equipment can be used to clean it. In the case when the diameter of the pipeline is 200 mm, a high-pressure mini washer is used. Its performance, which reaches 1250 liters. per hour at a pressure of 350 bar, makes it easy to remove blockages of medium severity. The advantage of this sink is that it has small size and is quite mobile, so it is successfully used even in places where it is not so easy to get.

The storm sewer system can deteriorate if it is connected to the public sewer leaving the house. In the event that a blockage has formed in that communication, then the drainage on the street in the yard may also stop functioning. In addition, the foundation of the house may deteriorate if it begins to be flooded as a result of the fact that melt water has stopped leaving the yard.

Note! It is not so difficult to create a storm drain, besides, if you do it in a timely manner, then maintenance will also not take much time and effort. In addition, parts of the building and adjacent structures will last longer, which will not dampen or rust from a lot of water standing in the yard.

In fact, the creation of a structure for collecting and discharging melt water and rainfall cannot be called a forced additional measure. This is a necessary project, which cannot be avoided during the construction and subsequent operation of the house, no matter if it is located in the city itself, on the outskirts or outside the city. In addition, if we talk about storm sewers located along the road, then this drainage system also quite well preserves the integrity of the road and other objects. Saving on storm water when designing the surrounding area around a certain building can later play a fatal joke - repairing the house and objects next to it will cost many times more.

Storm sewer maintenance refers to the installation of a special cleaning system that requires that all residue collected in the tank be removed from it. Therefore, a pump is required for this purpose. The oil products released during washing and accumulated in the block drain into a special container and are sent for disposal.

Cleaning methods

When the water drainage system on the site of the house or cottage is built and started to work, the foundation of the house will no longer become damp, the soil under it will not be washed out with water, and on the site of the owners it will not be necessary to bypass the puddles formed after the rain. However, such a system will require constant maintenance. This means that the pipes will require cleaning and flushing.

Typically, inspection and maintenance of the sewer system to drain storm water from the site is carried out several times a year, sometimes once. Without fail, such a check is carried out immediately after the departure of winter and the melting of snow, as well as in the fall, after the rainy season, which carry stones, sand and leaves with them into the pipes.

Note! Of course, cleaning should be carried out if a thorough roof repair was carried out not so long ago. Such prevention is also done if the house was plastered or insulated. The fact is that after carrying out such work, particles of mortar, bitumen, polystyrene foam, etc. could get into the storm sewer.

How do the professionals do it? There are several types of cleaning. Here are some of them:

mechanical;
hydrodynamic;
thermal;
chemical.

Now briefly about all cleaning methods. The first method, mechanical, involves the removal of traffic jams by removing them with a cable or other devices. When pipes are cleaned by the hydrodynamic method, this means that water will be supplied to them under strong pressure, which should break all blockages. The thermal method is essentially similar to the hydrodynamic method. But the water that is supplied to the pipes is heated to the boiling point, as a result of which the plugs soften and are easier to remove.

The last option, chemical, is more voluminous. You can use baking soda to clean various formulations from shops. However, it has a minus - an unpleasant odor and the likelihood of spoiling the skin of the hands or body when chemicals come into contact with them. Therefore, if it is decided to pierce the pipes with chemicals, you need to protect yourself from it by wearing a respirator and gloves, as well as long-sleeved clothing and pants.

Causes of blockages and how to eliminate them

One of the problems can be drains clogged with debris. The water that flows down them from the roof takes him out into the yard, and from there into the sewer, clogging it. Therefore, the gutters on the roof and the gutters leading down from them should be thoroughly cleaned, and the debris that has fallen into the yard should be collected and taken away.

Note! When cleaning drains, it would be a good idea to check if they are properly attached. It is also better to check their slope, because if it is absent, then the water will not drain well, and garbage will begin to collect in the gutters.

How exactly do you clean the gutters? As a rule, a mechanical method is used for this, that is, the use of a cable, and branches, fallen leaves and everything else are manually removed.

In cases where funnels for receiving water are protected by caps or grates are attached to them, blockages in them occur less frequently, since large debris does not penetrate into the pipes. However, if a blockage still appears, then in order not to remove the grilles, cleaning is carried out by supplying water through a hose under strong pressure.

Cleaning systems with open trays

When a storm drain with open drains is made on the territory of the site, it will not take much effort to clean it out. To do this, you need to go through several steps;

first of all, remove and put aside the grate that covered the hole;
remove all debris accumulated over time from the channel;
after that, rinse the channels with water pressure and you can put the gratings in place.

Such systems, where only one outlet is made under the drain, and the entire system is assembled from pipes hidden underground, are much more difficult to clean. Therefore, it is necessary to flush the pipes. As a result, with a strong pressure of water, you can break the formed sand plugs, heaps of garbage and wash it all away.

Use of special equipment

This method is suitable for storm sewers that have a small capacity. Typically, they have a diameter of pipes laid underground, no more than 200 mm.

When it is necessary to carry out emergency or scheduled maintenance work on sewers of large dimensions, it may not be possible without the intervention of specialists along with the use of special equipment. This is due to the fact that in wells arranged in sewers and in pipe cavities, a huge amount of sand and silt deposits can accumulate during operation. They clog, and their removal by hand becomes almost impossible.

For this purpose, many major cities today there are enterprises whose purpose is to service underground utilities.

What is required in order to properly clean the storm drain overgrown with dirt? First of all, you will need:

Canal washing machine.
Vacuum unit capable of pulling out sludge.

As a rule, all this technology is arranged on the bodies of sufficiently powerful cars. Some of these installations even have several of these functions, that is, they can break through the sewers with the pressure of water from a hydrant, and pump out stagnant sludge.

It should be noted that this technique is designed for the fact that the entrances to the storm drain will be made wide and strong enough, so the road must either be designed in advance or be operated already during operation. It should also be taken into account that a short hose that supplies water is more effective for sucking out clogged soil.

How to make a well

Such a well, also called a collector, is built according to the same principle. It lies in the fact that all the water entering this well through the pipeline (that is, after rain and drainage) then enters the general sewage system created on the territory. To prevent water from this well from falling back into the drainage system again, a check valve is provided in the collector well.

What should be the cover of the collector well? Firstly, water should pass freely through it, and debris should not get inside. Secondly, the cover cannot be located on the roadway. In those places where the movement of cars is intense, the well should have a telescopic neck, and its cover is designed so that it can redistribute the load on the ground located nearby.

Video: flushing storm sewers

Storm sewer (or stormwater) is one of the essential elements home improvement. The purpose of the storm drain is to collect rain or melt water and bring it out of the territory. Over time, the trays and pipes of storm sewers are filled with debris - branches, pebbles, leaves. As a result, a blockage is obtained, which reduces the efficiency of the system to almost zero. If this situation arises, it is imperative to clean the storm sewer. You can do this work yourself, or you can contact a specialized organization.

Cleaning methods

Like all communications, storm sewers need periodic maintenance. If a blockage has formed in the drainage channel, it is necessary to remove debris, flush channels and pipes. As a rule, cleaning is carried out 1-2 times a year:

In the spring, it is necessary to carefully inspect the sewers, when the bulk of the snow has melted.
It is advisable to revise the system in the autumn.

Important! It is necessary to audit the storm sewers if you performed roof repairs. The reason is that construction debris and pieces of bitumen get into the drainage system, which causes clogging.

How to clean the roof system?

When rainwater stagnates on the roof, you should start inspecting the stormwater drain from downpipes, funnels and gutters. Make sure these structures are not littered. If there are blockages, they must be removed. For this, mechanical collection of branches, leaves and other debris is quite enough.

Inlet funnels protected by caps and grates are less likely to become clogged.

Important! It is best to remove blockages in the funnels with water, which is supplied from a hose under pressure.

Open System Cleanup

When used on an open-type stormwater site, cleaning it is not particularly difficult. Cleaning the storm sewer is carried out in the following order:

Remove the grids that cover the trays.
Remove any debris that has accumulated in the canal.
Rinse the channels by directing water under pressure into them.
Install the grids in their original place.

Cleaning a closed system

It is more difficult to clean a closed-type storm drain from blockages. It is necessary to clean pipes placed underground in a hydrodynamic way - with water that is supplied under pressure. A strong jet of water destroys plugs of sand, dirt and debris, and the sewer system becomes operational again.

The effectiveness of the method depends on the power of the water pressure and the diameter of the pipes used. Eg:

If pipes with a diameter of 200 mm were used on the site (most often, this is exactly what happens), then an ordinary car wash that supplies water under pressure up to 350 bar is quite enough to eliminate blockages.
If you use pipes of a larger cross section, you cannot do without the help of a specialized company.

Important! To better clean the sewer better, water is supplied in two directions. First - from the water intake to the collector (in the direction of the natural flow of water), then - in the opposite direction.

Blockage Prevention

To less often have to resort to flushing storm sewers, you need to use special treatment facilities. For example, storm water inlets are equipped with special filters that trap debris and prevent blockages.

Filter types

Here is a list of cleaning devices that prevent storm drains from clogging quickly.

Sorption block.
Sand trap.
A filter that purifies water from oil products.
Separator, sump.
Station of UF-disinfection of water.

Important! When purchasing a particular treatment device, it is necessary to take into account the operating conditions of the stormwater. For example, for a plot of a country or private house, it is quite enough to buy a sand trap. Other elements are used in the installation of industrial sewers.

Design rules

In order to resort to large-scale clean-up works as little as possible, and even better - to avoid them, you must adhere to the following rules when arranging storm drains:

Storm sewer design in accordance with the requirements of SNiP.
Arrangement of sewers without too long or curved sections.
In places where there are turns, tie-ins, branches, inspection wells must be equipped.
It is desirable to use pipes with a smooth inner surface.
If sewerage cleaning needs to be done 1-2 times a year, then regular inspection and cleaning of sewage treatment plants should be regular, especially after heavy rains and leaf fall.

Important! In no case should you store bulk building materials near the storm sewer or equip a temporary dump. Timely cleaning of the territory from garbage is one of the critical factors uncontaminated storm sewer. If you neglect this rule, after the first rain, you may need to clean the storm sewers.

Sand traps: design features

Install a sand trap at the inlet to the pipe. Its device is extremely simple: water enters the device through the upper part, and pours out through the side holes located above the bottom level. Due to the difference in levels, a sump is formed. Sand and heavy debris settle to the bottom.

Important! Sand traps are made of polymer concrete or plastic. The most common option is a removable PVC basket. It has a small mass, and it is easy to clean it from accumulated debris.

Professional cleaning methods

Professional companies that provide such services use the following methods:

Mechanical - punching plugs and removing dirt mechanically.
Hydrodynamic - flushing storm sewers with a water jet, which is supplied under pressure.
Thermal - removal of contaminants with steam and hot water.
Chemical - the use of chemical reagents that destroy blockages, but are safe for pipes.

Important! The most common way to clean storm drains is mechanical.

Flushing of storm sewers using special equipment

Preventive or emergency work on large sewers requires the services of professional specialists and specialized equipment. The amount of sandy-silty deposits in wells and pipes can be measured in dozens cubic meters, and deleting them manually is simply unrealistic.

For professional cleaning of storm drains, sewer washing machines and vacuum suction units are used. The equipment is installed on the wheelbase of machines with a large load capacity.

Important! Some models of modern equipment perform both functions: pumping out sludge and flushing work using powerful hydrants.

Description of flushing technology:

A team arrives at the facility with a pre-filled washing machine.
A high-pressure hose is introduced into the well (to a depth of 1-2 m).
The flushing process is carried out with a water pressure of 180-200 bar.
Water washes away silt deposits, and they flow down to the well.
After washing the entire area, the hose is folded, while continuing to supply water. The quality of pipe washing will be better.
Silt deposits are cleaned from the well manually. With a large amount of deposits, sludge is removed by a sludge pump. In the sludge hopper, the dirt is separated from the water and can be reused.

Important! Emptying the sludge pump is carried out at a specially prepared site or at a waste landfill.

Pneumatic drain cleaning

This method is used when the deposits are petrified and are not amenable to hydraulic cleaning. The essence of the method is as follows:

Special pneumatic cartridges are introduced into the cleaning area, with the help of which local water hammers are created.
This leads to a short-term change in the geometry of the sewer pipe.

Important! This does not affect the integrity of the storm drain, but the cleaning is quite effective. The method is quite expensive, but in some cases the only possible one.

Proper planning and arrangement of stormwater drainage, its timely revision and cleaning, compliance with operating rules and simple preventive measures can avoid the use of expensive cleaning services.

Melt waters, heavy rains over time negatively affect the condition of the soil. He, in turn, renders the buildings unusable, the plots float in the water. Downpipes protruding from the roof cannot solve this global problem. The arrangement of storm sewers helps to get rid of such troubles. You can independently build this design, knowing the types of storm sewers and methods for their construction. For small-scale residential buildings, a simpler design and maintenance is used - an open storm sewer. The deep system is used more often in industrial buildings, rarely in private homes.

Mechanical. The method is simple and consists in the usual removal of plugs and cleaning the sewer from dirt. This is where sand traps are used. Baskets collect natural garbage of a large fraction in an undissolved state.
Physico-mechanical. Centrifuges and grease filters are installed to separate petrochemical products. Since without them, the oil turns into a solid consistency and the congestion is ensured.
Hydrodynamic. It is considered the most effective method. Water is pumped into pipes under pressure. It is difficult to do the work on your own. It is worth contacting professionals. Since this requires special equipment. Strong clogging leads to negative consequences: it erodes the foundation, forms puddles near the house. Therefore, in a critical situation, sometimes there is no other way out.
Thermal. This option uses steam or hot water.
Chemical. Are selected chemical substances harmless to pipes, but effectively removing blockages. When a chemical reagent enters the pipe, foam appears. For reliable protection against damage to the pipes, it is still necessary to rinse the pipes well after the procedures. method harmful to environment so it should only be used as a last resort. Work in protective equipment: respirators, masks, gloves.
In some cases, the hydrodynamic cleaning method is combined with the mechanical one, which is more common in practice.

Most effective method called complex cleaning. The system in this case is not only cleared of blockages various methods but also disinfected. Areas affected high risk, for example, according to the legislation of the Russian Federation, are equipped with treatment facilities.

Shallow trenches are buried in upper layer ground and covered with cells or nets. This makes it possible for people to move freely along the paths, while not feeling them at all.

Water gets into simple devices from various areas: blind areas near the house, open areas, driveways. It looks like an open storm sewer. It is not connected to the sewer in most cases. Water drainage rushes, for example, to flower beds, lawns. You can build it yourself from improvised means:

a barrel is being prepared, up to 0.7 meters long;
a hole is drilled in the ground with a drill, preferably to the sand;
a perforated pipe up to 1.5 meters long is inserted;
a barrel is installed on top of the pipe with through holes and covered with sand;
Concrete the distance between the top soil and the barrel. This will keep the soil from crumbling. Make the neck at a slight angle to make a hole in the form of a funnel;
a grate from the furnace is installed on top and fixed with concrete mortar.

The material for the trays can be plastic, polymer concrete, reinforced concrete. In order for the gutters to sit firmly in the ground, they prepare cement mortar and make them fastening structures.

An open system, due to its simplicity, is more often used in private homes.

Cleaning algorithm:

go up to the roof and start cleaning each gutter;
the second stage is baskets. They connect drainpipes;
remove the bars;
larger debris is collected in the funnels if the system is equipped with sand traps;
in the work they use a chopper, a scoop, a shovel. That is, everything that is at hand;
sometimes debris enters the drain pipe, in which case the hydrodynamic method is used;
connect the hose and direct water into the pipe under high pressure. The cork will be removed and work can be continued mechanically.

Cleaning a closed sewer

A closed stormwater system is more complex than an open one and includes the collection, drainage, and disposal of stormwater.

In order to build a structure, you can use point or linear drainage. Sometimes a combination of the two methods is used.

Closed sewerage allows not only to divert water from the roof of the house, but also from the entire site.

Behind the site of the house, a drainage system is being prepared, where water will flow from the entire site and the roof. To do this, trenches are dug, and pipes are laid out at a slight slope. The depth of their occurrence should not be less than the thickness of the soil freezing. A pillow of sand is laid under the pipes and compacted. Grooves are dug for trays. Gutters are planted on the cement mortar and covered with gratings. Pipes are laid from the well to connect it to the central collector by force or gravity. If the first option is selected, then the well is equipped with a pump.

For household needs, you can remove a separate drive.

To prevent clogging of the pipe, sand traps are installed. The cleaning process begins with them. The grate opens, and the baskets are freed from rubble, sand, gravel. Sometimes the pipes get clogged. In this case, simple measures are taken. They take a steel cable and move it forward with rotational movements until it finds a stop. This is a signal that a blockage has been found. Continue rotating movements until there is no free play. So the blockage has been destroyed. The last step is to flush the pipes from the hoses with water.

How often should storm drains be cleaned?

Serious blockages can be avoided if storm sewers are cleaned in a timely manner.

The first operation is carried out in the spring. When the snow still lies unmelted. The capacity of the storm drain is being tested. So that she can cope with the upcoming flood.

The second check in preventive purposes held in autumn. Storm drains collect garbage throughout the season and the release of it is mandatory.

If near the house were held construction works, then an unscheduled operation is also desirable.

Capital work on cleaning the drainage is carried out much less frequently, once every few years. During this period, deposits that accumulate on the pipes are removed and they are repaired, if necessary. Cleaning methods may vary.

When deepening the drainage into the soil, several activities associated with earthworks. You may need a pneumatic device with a shaft, and special nozzles for crushing large debris. Such cleaning activities should be done once every 4 years.

With the help of a pump and a hose, drains are flushed. The procedure is performed section by section, at the age of 15 once.

The work algorithm is as follows:

every detail must be accessible from all sides;
the pump is turned on alternately on each side of the pipe;
water is supplied under pressure;
through extensions, flushing and removal of dirt from each section of the system is carried out.
the method is considered the most effective, since all parts of the system are available for flushing, and dirt is crushed and removed under pressure.

Removing silting from drainage systems carried out in emergencies. Although the method is effective, the negative impact on soil quality, if household plot, renders saltpeter.

Cleaning principle:

deep drainage is freed from sod;
as soon as a layer of rubble remains, saltpeter is poured;
everything is abundantly filled with water;
the sod is put in place.

Drainage systems can serve for a long time if certain requirements are met:

keep the top layer loose. This will help absorb moisture well. exclude for such purposes the movement of heavy equipment;
install inspection wells to simplify maintenance;
clean the collectors at least once every three years.

Emergency drain cleaning

In addition to the planned cleaning of storm drains, unscheduled and emergency events are carried out.

One of the reasons may be blockages with large objects.

The second is natural anomalies, when a landslide falls, floods.

Prevention of blockages in storm sewers

Preventive measures help to deal with blockages in storm sewers. There are a number of cleaning elements that are used in various systems plum:

absorption blocks. The water supply throughout the entire length is equipped with small wells. Debris settles in them, leaving the pipes free of debris.
Settling tanks. Solid materials remain in the tanks, and the liquid flows out of them without impurities
Grease filters. They allow not to accumulate oil and oil residues on the walls of pipes.
Lattices, grids with small cells. The device does not protect against sand, dirt, but holds large objects.
Stations of ultra-violet disinfection. The service package includes diagnostics, signaling the contamination of pipes.
Separators.
Sand catchers. The device retains sand, prevents the penetration of gravel, soil particles.

The listed protective elements are installed depending on local conditions. It is prudent to put grease filters in areas where car repairs are carried out. Residues from oil products will not accumulate on the walls of pipes. It is convenient to install sand traps in a residential building. On an industrial scale, other protections are suitable.

The principle of operation of the sand trap, after installing it at the inlet of the sewer pipe, is as follows:

water enters the upper part of the structure;
its output occurs through the side holes;
the bottom is much lower, where particles of gravel and sand collect. As a result, water over the edge rushes into the pipes without impurities.

The material for the sand trap is taken from polymer concrete or plastic. The compartment where garbage is collected is removable for convenience. This is usually a basket made of polyvinyl chloride (PVC). The structure of the material retains durability, allows you to withstand sunny days and moisture.

Storm sewerage is a communication that collects and drains water that accumulates as a result of rain, melting snow and ice. Atmospheric precipitation that flows from the roofs of buildings Negative influence on the foundation, lead to the formation of puddles on the territory of the building, erode the soil.

Storm sewer cleaning is needed in order to atmospheric waters did not seep into natural water bodies harmful substances that can adversely affect the ecological state of natural resources and make water unsuitable for living organisms. After all, the speed of storm runoff from one hectare of the territory of the metropolis, with its gas stations, industrial facilities, cars, reaches 150 liters per second.

Properly designed, installed in compliance with the correct technology, storm sewer (drainage) allows you to qualitatively solve the problem on the territory of private houses, suburban villages, within the city to prevent destruction asphalt pavement and removing puddles from sidewalks and pavement hindering movement.

This communication consists of:

gutters, channels, trays designed to collect water and its further transportation;
storm water inlets for point collection of rainwater from the surface and installed under the downspouts of buildings, in the lowest places;
sand traps installed to prevent clogging of pipes due to sand and debris entering them;
sewer pipes laid in the ground below the level of soil freezing and connected to a system of channels, gutters and storm water inlets on the surface;
manholes that provide control over the operation of storm sewers (drainage) and its cleaning if necessary;
collector, which diverts wastewater to the place of their discharge into the reservoir.

As well as other types of engineering systems, the drain needs to be flushed and cleaned. Over time, various debris accumulates in pipes and trays: sand, leaves, stones, branches. As a result, blockages appear, from which the quality of the system is reduced and eventually reduced to zero. Then a thorough cleaning of storm drains is necessary and the price depends on how you will make repairs, on your own or contact professionals.

Types of storm sewers

The specifics of cleaning systems for the removal of melt and rainwater, their complexity and the need for professional equipment depend on the type of system.

Storm sewers are:

open, which is typical for small private households. It consists of shallow trays, is not connected to the sewer and diverts water to lawns and flower beds.
closed, which is more complex in design and maintenance. This design has underground pipelines through which water from the storm inlet enters the central sewer system through an internal well. This system is designed for large areas in cities with high building density.
mixed, which consists of elements of open and closed systems. In it, part of the way, water passes through the trays, after which it enters pipes located underground, and then into the sewer.

Storm sewer flushing

Cleaning storm sewers is a process that requires time and additional costs, therefore, in order to carry out this work as infrequently as possible, it is recommended to use special treatment facilities. These include:

filters for storm water inlets that trap large debris - branches, leaves, needles;
sand traps designed to extract from Wastewater heavy mineral impurities (sand);
settling tanks and separators designed for mechanical water purification, separation of oils, oil products or solid inclusions;
sorption blocks for post-treatment;
filters for high-quality water purification from oil products.

When choosing storm sewer treatment measures, it is necessary to take into account local conditions: for private houses it is enough to install sand traps, and for the production system all other elements will be required.

If a problem nevertheless arises, when choosing contractors to solve it, one should be guided by the requirements of quality, efficiency and price loyalty - the rules that form an impeccable reputation in the service market. It is these principles that the site company uses in its work, which offers qualified assistance in maintaining engineering systems.

Among the competitive advantages:

years of experience;
extensive client base;
modern equipment;
acceptable prices;
responsible approach;
efficiency;
round-the-clock operation;
guarantee for all types of work.

Storm sewer cleaning

For trouble-free operation of the system, experts recommend checking once or twice a year. A preventive inspection of the storm drain is mandatory in the spring, when the bulk of the snow melts. It is also recommended to conduct a planned audit of the state of communication in the fall.

If on the roof of the building were carried out repair work, an extraordinary inspection of storm drain networks is necessary, since construction debris and bitumen could get into it. These measures will help prevent many problems associated with disruption of the sewer, reduce the risk emergencies, save you from the financial losses that lead to repair work. In cases where blockages form in the water drainage channels, there is a need for hydrodynamic cleaning storm system, which consists in flushing channels and pipes.

Competent assistance in cleaning storm sewers is offered by the specialists of the site company, who have experience and knowledge of effective methods for professional cleaning of engineering systems. Timely contacting a specialized company will help you get competent advice and a full range of services aimed at ensuring effective work communications.

Depending on the nature of the problem, the site's professionals will determine the best way to fix it:

mechanical, which involves removing dirt and breaking through traffic jams;
hydrodynamic, which is the cleaning of the system with water supplied under powerful pressure;
thermal, usage-based hot water or couple;
chemical, which consists in the use of various reagents that destroy blockages. It is used in the chemical and oil refining industries, when it is necessary to neutralize especially dangerous substances.

The best results are obtained by using all cleaning methods in combination. Most often, the mechanical and hydrodynamic methods are used, but the advantage of turning to professionals is that experienced specialists will conduct high-quality diagnostics and help determine the most effective method elimination of blockages in the storm sewer (drainage). This will provide not only a prompt solution to the problem, but also cost optimization, because planned work is much cheaper than emergency work.

Gutter Cleaning: Performance Basics

In cases where water has begun to stagnate after rain, the system should be inspected from the roof of the building, on which drainpipes, gutters and funnels are located. Thus, you can make sure that these elements of the system are not filled with debris, and if a blockage is detected, remove it mechanically by collecting accumulated leaves, branches and other debris.

Protection of water intake funnels from blockages is provided by special gratings or caps, so the likelihood of blockages is small. However, if the work of the drain is broken, then professionals will clean the funnels using the hydrodynamic method by supplying a jet of water from a hose under pressure into them.

Cleaning open-type systems is easier to perform; for its implementation, the professionals of the site company will take the following actions:

carefully remove the grilles covering the trays;
remove the debris accumulated in the canal;
thoroughly flush the channels with a stream of water under pressure;
put the grates in place.

Cleaning a closed sewer system is a more complicated process, since it involves flushing pipes that are laid underground. In this case, a jet of water under pressure will be supplied to the system: a strong pressure destroys plugs from debris and sand, washing out contaminants from communications. High-quality work of specialists will ensure the complete restoration of storm sewer performance, especially if it is necessary to flush large-section pipes (over 200 mm), which require professional equipment.
