When designing a storm sewer according to SNiP requirements, its ability to self-clean is assumed. However, it is impossible to take into account all possible factors (different precipitation rates, pollution due to construction and other work carried out near the site, etc.) that contribute to the formation of blockages. Any system sooner or later needs cleaning.

Methods for cleaning storm drains and equipment used by Kanalservice
Storm sewer cleaning and maintenance is carried out by our company’s specialists using the following equipment:
- Mobile devices high pressure Kranzle 2160 TS and other models. With their help, contaminants are washed away from grates, gutters, open trays and channels, drainpipes. This equipment is also used for hydrodynamic cleaning of deep drainage systems with a diameter of up to 100 mm.
- Electromechanical devices Rothenberger R650, R80 and Ridgit K-45. With their help, we remove solid contaminants of organic and inorganic origin from the system (rags, hygiene products, tree branches and roots, construction garbage etc.).
- Hydrodynamic installations and sewer cleaning machines on automobile chassis. With the help of hydrodynamic cleaning of storm drains, even the most complex blockages are eliminated due to the influence of a powerful flow of water under pressure (in some cases heated to a certain temperature).
- Sludge pumps KO-507AM1, AKNS-10 and TKM-620 for pumping out contaminants from storm wells, storm water inlets, sand traps and other system components.
In some cases, to clean storm drains, it may be necessary to use specialized chemical compositions. Our specialists will select the appropriate products based on the materials from which the storm drain elements are made and ensure high-quality removal of contaminants.

Let's consider the real situation of storm sewer contamination with compacted sand.
For example, let’s take a section of an external storm drain sewer network with a pipe diameter of 300 mm, a length of 100 meters, with five sewer wells two meters deep, the interval between wells is 25 meters, the diameter of the wells is 1 meter. The degree of contamination of pipes is 90%. The subject of the contract is the cleaning of storm sewer pipes using the flushing method and removal of washed sediments.
Sewer flushing is carried out by a complex of two special machines: a sewer flushing machine and a sludge extractor.
The internal volume of the pipe section of the storm sewer to be cleaned is 7.1 cubic meters. Considering the percentage of contamination, there is 6.4 cubic meters of sediment in the pipes. Five wells contain another 1.3 cubic meters of sediment. A total of 7.7 cubic meters of sediment needs to be extracted.
But the sand in the pipe is in a compacted state and when washed out, the volume of extracted sediment, taking into account the technology of draining water from the suction pump, will be 15 cubic meters.
When pumping out the sludge of liquid consistency washed out of the pipe, partial separation and reverse discharge are carried out in the suction pump. rinsing water, due to which the viscosity of the sediment increases significantly.
The KO-507A sludge pump holds 7 cubic meters of sludge. This means that it is necessary to remove either two suction pumps if the sludge volume is 14 cubic meters, or three suction pumps if the volume is more than 14 cubic meters.
REMOVING SLUDGE TO A LANDFILL FOR DISPOSAL - the process is not fast, especially if your property is in the city center. You can bring three suction pumps to the site. But this will lead to higher costs for pipe cleaning. The optimal solution is the construction of a sludge platform on site followed by removal of dried sediment using garbage containers.
To wash out the sediment, water is required, which is filled into a sewer washing machine.
Water consumption of the KO-512 sewer cleaning vehicle when washing pipes external sewerage is 200 liters per minute. Therefore, 9 cubic meters. of water from its tank, it will pour out, taking into account the remaining balance, in 40 minutes.
To wash out the caked sediment in the pipes and wash it into the storm sewer wells to fill one suction pump (7 cubic meters), it is necessary to drain three tanks of water (27 cubic meters) - this will take two hours of pure working time. But taking into account the arrival and departure of the sewer flushing vehicle to refill with water, this time will stretch to three hours, plus the time for refilling 27 cubic meters. water. The refueling time and, ultimately, the time of work depends on how high the pressure in the hydrant is. It is also important where the hydrant is located and at what distance from the place where the sewer is flushed.
It is optimal when both the drain point of the suction pump and the hydrant for refueling the sewer washing machine are located within no more than one kilometer from the section of the sewer pipeline being washed.
There is a method of working on recharge. This is when the sewer flushing machine is constantly connected to the hydrant and does not need to drive to a gas station, but such successful situations are extremely rare.
What can increase the operating time and, therefore, the cost of cleaning storm drains
- difficult access to sewer wells;
- sewer washing machine and sludge extractor - the vehicles are large and block a significant part of the roadway, and if they are constantly asked to move from place to place to clear the passage, this will significantly increase the work time;
- If sewer wells are on the ground, it is necessary to arrange flooring, since two cars together weigh 40 tons and can get stuck on the ground;
- difficult access to the hydrant or the hydrant is located far from the sewer flushing site;
- difficult access to the place where the suction pump is drained or unloaded;
- disposal of sewerage flushing products at the regional landfill;
FROM THIS LIST IT IS SEEN THAT THE COST OF CLEANING AN EXTERNAL SEWER BY HYDRODYNAMIC WASHING METHOD DEPENDS ON THE QUALITY OF ORGANIZATION OF THE PROCESS. AND ORGANIZING THIS PROCESS IS THE TASK OF THE CUSTOMER REPRESENTATIVE.
Returning to the topic of the article, there is reason to believe that, in a good situation, the example work of flushing a section of an external storm sewer can be completed in a 12-hour shift. If necessary, the work shift can be extended by another hour or two, if it is clear that we will finish in one day. If there are difficulties, the work has to be rescheduled for another day, which entails an increase in the cost of the work.
Dacha owners and country houses They know firsthand how important it is to equip storm drains so that melted and rainwater They did not spoil the finish and did not flood the foundation. But it is not enough to organize a proper wastewater disposal system - without regular care it will quickly fail and “report” this with streaks on the walls and puddles near the house during a heavy downpour or spring drop.
To prevent this from happening, it is necessary to carry out timely prevention and be able to quickly remove blockages. Therefore, we will consider in detail what methods the technology for cleaning storm drains has, depending on the type of its design. Also in this article we focus on the causes of clogged drainage systems and preventive measures.
The purpose of storm drains is to collect water from fallen precipitation and discharge it into a special reservoir or simply outside the site through a pipeline network or drainage gutters. Any drainage design can cope with this task.
But to choose the most effective method cleaning and preventing sewer blockages, first you need to find out which system protects your home from rain and melted snow.
Open (superficial) – the most cost-effective and simple design, which is equipped country houses. It is a complex of trays, pipes, gutters that run along the roof and walls of the building -. Through them, water flows to water intake points - surface drainage ditches equipped along the perimeter of the entire site or only local area, and is discharged into the ground.
Unconditional advantages open system: affordable price of components, simple installation and easy cleaning. But with significant precipitation, it may not cope with water flows
Closed – top part storm drains are the same system of pipes and gutters, only collected waters are collected in underground sewer pipes, where other wastewater from the house also flows, then into the collector, and only then is it discharged into drainage system. In some cases, a pump is additionally installed that regulates the speed of movement of the wastewater.
This system does an excellent job of removing excess moisture from the site without flooding the soil, the formation of puddles and other flaws in the operation of open storm drains. The disadvantages include expensive installation.
In addition, it may be an overwhelming task for a non-professional to make the correct calculation required quantity components, length and diameter of pipes, determine the depth of their installation, the required slope and other nuances. Detailed analysis We have given the features of the design and calculation of storm sewers.
Storm drainage can be called the most important element, which is used in the improvement of not only the capital, but also any other settlement. It is needed so that when the snow melts and when it rains, it can be immediately removed from the site. excess water. But annual storm drain cleaning, as it may become clogged over time.
Causes of blockages in storm drains
It is known that storm sewers consist of pipes, trays and wells. On the streets of Moscow there are trees from which leaves are falling. When there is heavy rain, they fall through the grates into the sewer system. 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 service such as storm drain cleaning 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 clog on your own. It is quite possible that you will first have to use video diagnostics of the sewer system. After all, if branches get there, you will need very serious equipment to remove them. In this case, cleaning the storm drain will cost the customer more.
Basic methods for cleaning storm drains
Experts recommend cleaning such sewers twice a year. In any case, this should be done in the spring, when the snow melts. A lot of debris will fall into the sewer with melt water. It is necessary to get rid of it as quickly as possible. Otherwise, at the first heavy rain, a blockage will form.
There are different methods for cleaning rulers. The most expensive is hydrodynamic cleaning of storm drains; prices for it can be found in the ZasoroLiquidator company. But the following professional methods are also used:
- - mechanical, when the blockage is simply broken through;
- thermal, where highly heated water or steam is used;
- chemical, using certain reagents.

Often hydrodynamic method for cleaning storm drains used together with mechanical. After all, you must first break through the blockage, and then wash off all the accumulated debris. A nozzle on the edge of a flexible hose will not always cope with a serious blockage if there are branches and pebbles in addition to leaves. It must be taken into account that storm drainage can be either open or closed type. If she open type, the blockage can be removed mechanically. For a closed sewer system, only hydrodynamic flushing is needed. So there is no way to do without the services of the company "ZasoroLiquidator".
