Storm drainage – essential element landscaping of the territory. Used to collect and discharge excess water, the system requires cleaning the pipes of debris: leaves, branches, dirt and sediment of fine-grained insoluble particles. To ensure that the efficiency of the pipeline always remains ideal, you can do the cleaning yourself, or you can use the services of third-party organizations.

After putting storm drains into operation, you don’t have to worry about undermining the foundation or accumulation of excess moisture in the garden, but from time to time it won’t hurt to inspect pipes, trays, gutters and other elements. Cleaning events are carried out twice a year: in spring and autumn. In the spring after the melting of the main snow mass and the melting water, in the fall before preparing for cold weather and the upcoming (if necessary) conservation of the system.

Important! When conducting roofing works inspection of the drainage structure is necessary in order to promptly eliminate possible blockages of pipes with bitumen, construction waste and other slag.

Cleaning storm sewer professional methods may be different:

• Mechanical process represents knocking out plugs and removing dirt accumulations;
• Hydrodynamic– flushing pipes with water pressure;
• Thermal - use steam or boiling water for cleaning;
• Chemical means washing with chemical elements, inert to the materials from which the pipes are made.

Practice shows that mechanical cleaning of storm drains is most often used.

Cleaning storm drains: nuances and opportunities

Cleaning roof systems

In case of stagnant water, you should start by inspecting the roofs of buildings. This is where drainage gutters, funnels, and pipes are located. When inspecting, you need to make sure that all elements are free of debris, and if a plug is found, remove it mechanically, that is, by collecting branches, leaves and other debris.

Equipping water inlet funnels with caps will help avoid blockages, however, if water stagnates, it will be worthwhile to inspect all devices. Funnels are cleaned using the hydrodynamic method - by supplying water under high pressure.

Cleaning open structures

1. Remove the tray grids;
2. Clean debris from channels;
3. Rinse the trays using a hydrodynamic method;
4. Mount the lattice structures in place.

Cleaning closed storm drain systems

If an underground structure is clogged, clearing the route can take a lot of time and effort. It is best to also use the hydrodynamic option, which involves supplying a stream of water under good pressure. If the blockage is not severe, the water will wash out all deposits of dirt and large debris from the pipes. Pay attention to the diameter of the pipeline: when the cross-section is 200 mm, you can use a regular car wash, creating a pressure of 350 bar. But for larger diameter pipes it is better to use special equipment.

Important! To make cleaning as effective as possible, it is better to supply water first in the direction of the flow, and then against it.

Preventing blockages

To avoid resorting to the services of professionals and to reduce technical inspection and cleaning of storm drain pipes, preventive measures are used. It is better to equip rainwater inlet structures with filters that retain large branches, pine needles, and leaves. It is also a good idea to use elements such as:

• Sand traps - mounted at the entrance to the pipe. The working principle is that water enters central part, comes out on the sides through holes punched much higher than the bottom. Garbage, sand and other insoluble elements fall into the sump.

Important! Sand traps are made from different materials: plastic, polymembrane. And to make cleaning the sand trap chamber easier, a removable PVC basket is placed in the niche.

• Sorption blocks serve to absorb oils and further remove them along with debris.
• Filters for cleaning All fats are collected from petroleum products and, by binding individual elements into conglomerates, they help completely remove compounds from liquid streams;
• Disinfection settling tanks and separators– are not always required. If water is used only for technical needs, settling tanks, like separators, do not need to be installed.

When choosing the arrangement of treatment facilities for storm drains, you need to pay attention to local conditions: in a private house there are enough sand traps, and the remaining elements are already available in the sewer system diagrams.

Pipe cleaning prevention drainage sewer- an event that needs to be given due attention. Otherwise, you will have to break through plugs and clear blockages quite often. It is a good idea to equip the structure with a system of filters that remove debris from the flows before excess moisture enters the pipeline.

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

Cleaning storm drains is necessary to ensure that they do not leak into natural bodies of water along with atmospheric waters. harmful substances that can have a negative impact on the environment natural resources and make water unsuitable for living organisms. After all, the speed of storm water runoff from one hectare of a metropolis, with its gas stations, industrial facilities, and cars, reaches 150 liters per second.

A well-designed storm sewer (drainage system) installed in compliance with the correct technology allows you to qualitatively solve the problem in the territory of private houses, country villages, and within the city to prevent destruction asphalt pavement and eliminating puddles from sidewalks and road surfaces hampering movement.

This communication consists of:

• gutters, channels, trays designed for collecting water and its further transportation;
• storm water inlets for point collection of rainwater from the surface and installed under drainpipes of buildings, in the lowest places;
• sand traps installed to prevent clogging of pipes due to sand and debris getting into them;
• sewer pipes laid in the ground below the freezing level of the soil and connected to a system of channels, gutters and storm water inlets on the surface;
• inspection wells that ensure monitoring of the operation of storm sewers (drainage) and cleaning them if necessary;
• a collector that carries wastewater to the place where it is discharged into a reservoir.

Just like other types engineering systems, the drain needs flushing and sewer cleaning. 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’s operation decreases and eventually comes to zero. Then a thorough cleaning of storm drains is necessary and the price depends on how you will carry out the repairs, yourself or contact professionals.

Types of storm drains

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

Storm drainage happens:

• open, which is typical for small private households. It consists of shallow trays, is not connected to the sewer and drains 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, water passes part of the way through trays, after which it enters pipes located underground, and then into the sewer.

Storm sewer flushing

Cleaning storm drains is a process that takes time and additional costs, therefore, in order to carry out this work as rarely as possible, it is recommended to use special wastewater treatment plants. These include:

• filters for rainwater inlets that trap large debris - branches, leaves, pine needles;
• sand traps designed to separate from Wastewater heavy mineral impurities (sand);
• settling tanks and separators designed for mechanical cleaning water, separation of oils, petroleum products or solids;
• 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 production system All other elements will be required.

If a problem does arise, when choosing performers to solve it, you should be guided by the requirements of quality, efficiency and price loyalty - 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 maintenance of engineering systems.

Storm drain cleaning

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

If there were carried out on the roof of the building renovation work, an extraordinary inspection of the storm drainage networks is necessary, since it could have gotten into construction garbage and bitumen. These measures will help prevent many problems associated with sewerage disruptions and reduce the risk emergency situations, will save you from financial losses that result from repair work. In cases where blockages form in the water drainage channels, there is a need for hydrodynamic cleaning storm system which involves flushing channels and pipes.

Competent assistance in cleaning storm drains is offered by specialists from the site company, who have experience and knowledge of effective methods for professional cleaning of engineering systems. A timely contact with a specialized company will help you receive competent advice and a full range of services aimed at ensuring efficient work communications.

Depending on the nature of the problem, the professionals of the site company will determine the best way eliminating it:

• mechanical, which involves removing dirt and breaking through plugs;
• hydrodynamic, which involves cleaning the system with water supplied under powerful pressure;
• thermal, usage-based hot water or a couple;
• chemical, which consists of using various reagents, destroying blockages. It is used in the chemical and oil refining industries when it is necessary to neutralize particularly hazardous substances.

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

Cleaning Gutters: The Basics of Effectiveness

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

Water intake funnels are protected from blockages by special grilles or caps, so the likelihood of blockages occurring is low. However, if the operation of the drain is disrupted, then professionals will clean the funnels using the hydrodynamic method by supplying them with a stream of water from a hose under pressure.

Cleaning systems open type easier to implement; to carry it out, the professionals of the “site” company will take the following actions:

• carefully remove the gratings covering the trays;
• remove debris accumulated in the canal;
• thoroughly rinse the channels using a stream of water under pressure;
• will install the gratings in place.

Cleaning the sewer system closed type more difficult 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: strong pressure destroys plugs of debris and sand, washing away contaminants from communications. High-quality work of specialists will ensure full recovery the performance of storm sewers, especially if it is necessary to flush large cross-section pipes (over 200 mm), which require professional equipment.

A storm drain is designed to drain water resulting from precipitation. Almost all areas of factories, factories, business parks and all residential areas of the city are equipped with a wastewater disposal system. We can observe the result of the drainage system after heavy rains and thunderstorms, when water fills roads, courtyards and industrial areas.

The result of poor rainfall drainage is clogged storm drains. Sand, small debris, branches and leaves - all of this entering the sewer system collectors form a dense layer that prevents the passage of wastewater inside the storm sewer. If cleaning storm drains residential buildings and courtyard areas are the prerogative of housing and communal services, then entrepreneurs have to look for contractors to clean storm drains and pump out silt and sand.

Types of storm drains.

There are several ways to organize wastewater disposal. There are two main types of storm drains:

• Open sewerage - mainly private houses and small areas. To prevent the destruction of the foundation, trays (gutters) are installed around the roof through which water from precipitation is drained to lawns or filter wells. This system the simplest and requires virtually no maintenance, with the exception of cleaning leaves and dirt in spring and autumn.
• Closed drain system - used on large areas, in cities, in enterprises, factories, etc. In addition to the task of draining and recycling wastewater, a closed system eliminates the ingress of wastewater into the soil, as well as various discharges of water or other production waste. Thus, a closed sewer pipeline performs the function of draining wastewater and maintaining sanitary and epidemiological standards.

There is also a mixed system, but the basic principles are described above. Now it becomes clear that if you do not carry out maintenance closed system storm sewer, then you can also get ecological problems on your territory, therefore, by carrying out scheduled cleaning of storm drains, these problems can be avoided.

Features and price of drain maintenance.

The price depends on several factors:

• The diameter and length of storm sewer pipes are two main factors that determine how much dirt needs to be removed from the pipeline when cleaning storm drains. The larger the diameter of the pipe, the more sand and other debris may be contained in the pipe. Thus, the thicker and longer the pipeline, the more silt and dirt will have to be pumped out. But before you start pumping with a suction pump, it is necessary to wash out the silt and sand.
• The distance of the hydrant from the sewer flushing service facility - in order to wash away and wash away dirt from the pipes, a lot of water is needed, which is filled into the sewer flushing machine for further use. Thus, if two or three tanks are needed to provide high-quality services, a nearby hydrant for pumping water into the sewer cleaning machine will reduce the time and fuel spent on refueling the tank, which means it is possible to complete the work in one day.
• Disposal of pumped sludge and waste - any sludge pump has its own volume, which is filled not only with dirt pumped out from the sewer, but also with the very water used for flushing, so the waste must be taken to a landfill for disposal. Waste removal also takes time and resources. A complex and time-consuming service: cleaning storm drains, the price includes waste removal and disposal.
• The location of the wells through which cleaning and pumping out of dirt also plays a role. If the entrance to the wells is located on the ground, then before starting work it is necessary to make and install a flooring so that the suction pump and sewer washing machine do not get stuck.

Thus, the cost of flushing pipes is influenced by a large number of nuances and it is impossible to calculate the final cost without knowing all the parameters of the object. Storm drain cleaning - basic cost:

Name of works	Prices in rubles	Peculiarities
Planned work.
Washing of external sewer system with pipe diameter up to 250 mm	from 200	Minimum crew call from 11,000 rubles
Cleaning of yard sewerage with a pipeline diameter of 300 - 500 mm	300 per meter of pipe	Price minimum order from 14,000 rubles
Scheduled flushing external sewerage with pipe diameter from 600 mm	from 500 per meter	The minimum order cost is 26,000 rubles.
Grease traps with removal of reinforced waste	from 1500	The minimum wage is 12,000 rubles.
Emergency removal of blockages in pipes between wells with a diameter of 250-300 and 600 mm	from 12000 to 15000	An important role is played by the type of emergency vehicle used and its carrying capacity (gazelle 3 tons, vehicle over 3 tons.)

In addition, if the work lasts for several days, the cost will also increase. Based on all the nuances, we can conclude that the better the storm sewer cleaning is organized, the cheaper the cost and the shorter the time it takes to provide services. You can reduce costs in the following ways:

• If the hydrant for refueling is located next to the sewer washing machine and it is possible to organize refilling, that is, to avoid interrupting the operation of the equipment for refueling with water. Then all work can be completed in two to four hours, instead of two days.
• Avoid interruptions in the operation of equipment to clear passage. If you properly organize traffic around the location of the wells, you can also reduce the time frame.
• Organize a mini landfill for dumping silt and sand near or directly at the site, followed by waste removal. In this case, time is also saved on traveling equipment, which means cost.

The efficient operation of drainage systems depends on high-quality and periodic maintenance. Clogged communications lead to the accumulation of wastewater, difficulty moving around the territory, and destruction architectural elements, flooding basements and undermining the foundations of buildings.

– a communications system that serves to collect and drain melt and rainwater from the territory of individual buildings and cities as a whole. Like any other sewer system, the storm drain tends to get clogged.

Cases clogged storm drain, in which there is a need for emergency drainage cleaning:

• if the system is filled with leaves, branches, plant roots or sand that prevents rainwater from draining;
• when pollutants and viscous liquids enter the system;
• in case of ice formation on the walls of the collectors;
• when unpleasant odor from wells and drains.
