At the moment, human genius has invented many ways to clean sewers. The most popular and in demand are hydrodynamic, mechanical and chemical.
Hydrodynamic sewer cleaning rightfully holds the palm. It is often used when others are powerless. Its essence lies in treating the internal space of the pipe with a high-pressure water flow, which is selected depending on the diameter of the pipe.
Today, hydrodynamic sewerage cleaning is carried out according to the following rules:
A hydrodynamic sewer cleaning machine delivers a stream of water into the pipe through a special hose, which is equipped with several holes looking back at an angle of 15 - 45° relative to the axis of the hose.
After turning on the high pressure, the hose moves deep into the pipe, whipping and peeling off sediment and blockages. After covering a certain distance (usually one or two intervals between inspection wells), the drum mechanism turns on, which pulls the hose back along with the blockage. Hydrodynamic pipe cleaning is also effective because the entire process can be completely mechanized.
An important factor that you should pay attention to when cleaning is water consumption.
So for domestic sewers with a pipe diameter of 250-300 mm, 30 liters per minute is sufficient. It is worth noting that this figure applies to pipes located outside buildings. To effectively clean the internal sewerage system, 15-20 liters per minute is sufficient.
At industrial facilities these numbers will be much higher. A hydrodynamic cleaning machine must provide a water pressure of 200 atmospheres. This value is optimal for removing any blockages and restoring the functionality of the sewer system.
Hydrodynamic pipe cleaning is carried out by special machines, the standard equipment of which includes an electric motor, a high-pressure hose, a nozzle and a pump.
The operating principle of such machines has already been described above. When purchasing, be sure to pay attention to the nozzles, the nozzles of which must have the opposite direction. If they are located differently, hydrodynamic cleaning of pipes will become impossible.
The type of nozzles is selected depending on the nature and duration of the blockage. An injector with an additional front-firing nozzle is the most effective and in demand. The front fight clears space for the hose to move further.
Hydrodynamic pipe cleaning is most effective when dealing with grease, silt or sand.
We dare to assure you that flushing the pipes does not violate the integrity of the system and maintains the strength of the joints. Among other things, hydrodynamic sewer cleaning does an excellent job of removing construction debris, sprouted roots and other solid deposits, thanks to the presence of special nozzles in our arsenal. Our company provides only high-quality services for the use of hydrodynamic flushing when solving problems in the operation of sewer systems.
Over the previous years, a lot of specialized equipment was imported to Moscow, but none of them will work correctly if it is operated by an illiterate person. Our hydrodynamic cleaning machine is operated by professionals with 30 years of experience in flawless work in this sector of the national economy.

High-pressure washers are also used to clean drains, the characteristics of which can be found here
Workers providing landscaping services or repairing utility lines are regularly faced with the task of cleaning sewers.
To perform this operation, workers use special machines with manual or electric drive.
Since blockages do not happen every day, renting a sewer cleaning service is a more rational option than purchasing equipment as your own.
Working principle of the clog removal machine
To clear a clogged pipe, you need to insert a cable into the working gap and, by rotating it, exert mechanical force on the plug.
There are several types of attachments that are designed to remove specific types of clogs.
Having determined the nature and composition of deposits on the pipe walls, the operator selects the appropriate nozzle.
Electric drum-type sewer cleaning machines can handle any blockage.
A powerful motor imparts a high rotation speed to the cable, which allows mechanical destruction of grease or lime plugs and harder objects.
Even tree branches that have entered the storm drainage system can be removed using an electrically driven device.
Manual sewer cleaning machines are suitable for less complex work and are used for cleaning short-distance domestic drainage systems.

Our equipment is kept in excellent technical condition, and our staff is polite and competent.
Today, not a single city, town or large enterprise can do without sewer networks, gas pipelines, and water pipelines. Any pipeline must be durable and reliable.
But, like any system, the sewage system cannot function forever without interruptions: over time, the pipes become clogged, deposits and scale appear in them, and silt can also settle. The consequences of blockages in pipes are: reduced pipe capacity, premature wear and destruction, increased water consumption, all this leads to frequent unscheduled repairs. Accordingly, sewer users have to spend more money on heat and electricity, face problems with lowering the temperature in the building, and in critical situations there is an unpleasant odor coming from the sewer, as well as stagnant water in sinks, bathtubs and toilets.
To prevent emergencies from occurring, you need to regularly carry out preventive work to maintain pipes in working condition, periodically clean them using a plunger or special means, and also follow simple rules that will help prevent blockages from appearing: drains of bathtubs, sinks, and shower stalls should be a grill that does not allow hair and small debris to pass through. After washing very greasy dishes, it is recommended to leave the hot water running for a couple of minutes to rinse off any remaining grease. And, of course, you shouldn’t throw large garbage down the toilet.
But, if a blockage does occur, experts do not recommend cleaning the pipes yourself. Most often, such attempts do not solve the problem; on the contrary, unprofessional cleaning often leads to breakdown, which will require expensive repairs.
Only professional pipe cleaning can effectively eliminate any problem that arises. offers a wide range of high-quality services for servicing sewerage systems in residential buildings, public buildings, and industrial enterprises. Our specialists carry out scheduled and emergency cleaning of sewer pipes using modern techniques.
There are several ways to clear clogged internal drains:
- hydrodynamic; mechanical; thermochemical.
Each method has its own advantages and disadvantages. Before you settle on one of the methods for clearing your sewer clog, it is important to inspect it to determine the level of contamination and identify problem areas.
Only after carrying out diagnostic measures can you accurately determine which of the existing methods will be optimal in a particular situation and what equipment can be used to successfully clean sewer pipes.
The first thing is to understand what diameter of sewer pipes we will service
Capacity/diameter
- 24 l/min 200 bar will effectively clean pipes up to 150 mm
- 40 l/min 200 bar will effectively clean a pipe up to 200 mm
- 55 l/min 150 bar will effectively clean pipes up to 300 mm
- 75 l/min 150 bar will effectively clean pipes up to 400 mm
- 100 l/min 120 bar will effectively clean a pipe up to 500mm.
It is important to choose not the most powerful, but the most optimal pipe diameter. If the main diameter of the pipes that we will clean is from 100-300 mm, your choice will be a device with a capacity of 55 or 75 l/min. If for such diameters we choose a device of 100 l/min, this will entail, firstly, an increase in the cost of the equipment, and secondly, an increased consumption of water (our supply is limited by the capacity from which the device is powered and this is usually 1000 liters).
Hydrodynamic cleaning method.
This method allows you to safely and effectively clean a sewer pipe. The principle of this method is that for cleaning they use streams of water supplied under high pressure by special devices: a high-pressure pump (up to 300 atmospheres) and cleaning heads. Water enters the pipe through a special hose through nozzles of various shapes and sizes (Fig. 1). Under the influence of the jet, dirt and blockages are peeled off and removed. Hydrodynamic cleaning of sewer pipes involves the use of a portable unit or a special machine.
Device
The pipe washing unit is mounted on a three-axle KAMAZ-65115 vehicle chassis. It includes:
- Large capacity water tank.
- Pump and its drive, providing high pressure water supply.
- A high-pressure hose (HHP), equipped with a rotating winding drum for ease of transportation.
- Hydraulic system.
- There are several types of wash heads.
- Optional equipment.
During the modernization of the KO-512 model carried out in 2010, the previously used domestic pump 1.3PT-50D1U2 was replaced with an analogue of the Italian production HPP GL 212/150, which had better characteristics and smaller overall dimensions, which facilitated the layout of the pumping unit and the laying of hydraulic mains. The pump is driven from the chassis engine through the power take-off.
The all-metal body has a tank and two compartments closed with roller shutters. In the rear there is a drum with a supply hose, in the front there is a pump and the equipment necessary for its operation. The presence of two Webasto heaters (Germany) ensures a stable temperature in all compartments, allowing the machine to be used almost all year round. The efficiency of maintaining operating temperature is increased due to the installed thermal protection of the compartments.

Mechanical cleaning of the sewer system.
This method involves the use of a flexible shaft.
This is a steel cable, consisting of several layers of strong steel wire, with a shell in the form of a tightly wound spring-spiral. The length of the cable can reach 50-60 m. The cleaning process involves rotational and translational movements of the cable (Figure 2).
The flexible shaft rotates by an electric motor, and with the help of a gearbox it is fed into the pipeline. This method is suitable if it is necessary to remove deposits of crushed stone, silt, construction waste and other debris from pipes. Very often this method is used to clean storm drains.
Key parameters of sewer flushing devices
The correct choice of sewer cleaning equipment suitable for your needs directly affects the quality of the cleaning operations carried out with its help. In other words, it is extremely important to buy a sewer cleaning machine that is suitable for solving specific problems. We strongly recommend that when choosing, you rely on the following parameters:
- Pump power.
- Engine type and size.
- Mobility.
- Volume of the water storage tank.
- Availability of special attachments.
- Length of the hose used.
Before going to the store, you should study the features of each of these parameters.
Thermochemical cleaning method.
This method is characterized by the use of hot water and strong chemicals. Aggressive compounds destroy deposits in sewer pipes and remove formed plugs. For an enhanced effect, foam and surfactants are used, which are selected depending on the thickness of the deposits and the degree of wear of the pipes (Figure 3).
This allows you to quickly and effectively remove softened debris. The last step is flushing the sewer with a stream of clean water. But it is worth remembering that some of the chemicals used in such cleaning are toxic and can harm people’s health, so you should carefully select the substances used and, if possible, use an alternative method of drain cleaning.
Each of the methods is certainly effective and popular.
It is important to choose the ideal method for each unique situation. But the most universal, cost-effective and safe is the hydrodynamic method. Cleaning pipes using hydrodynamic machines is the most common method in professional maintenance of sewer systems.
Today, every water utility has at least one sewer cleaning machine. Its main advantages are that it cleans pipes carefully, which ensures their safety, does not require dismantling the pipes, there is no harmful chemical effect on the pipeline, people and the environment, and does not emit dirt and dust during operation of the installation. Moreover, this method allows cleaning at sub-zero temperatures, when the pipes are frozen and ice plugs have formed in them.
How to choose a drain cleaning company

Sewerage from scratch» Pipes
The days of unattractive-looking and horrific-smelling gutters are long gone.
The installation of sewer systems completely solves the issue of disposing of liquid household and industrial waste. But at the same time a problem arises: the pipes and channels are gradually covered from the inside with grease and dirt, in which solid particles are retained. Over time, serious blockages form.
There are different ways to cope with this problem. One solution is a drain cleaning machine. This technique, when executed well, has many advantages:
- high cleaning power, ease of use, durability.

Operating principle of cleaning units
Most of us are familiar with household drain clogs. They are usually eliminated mechanically (with plumbing cables, plungers) or chemically by pouring Crotyl or special compounds into the drains.
In relatively simple cases, such methods give excellent results. For more serious blockages, including in the housing and communal services system or in industry, other measures are required. In such situations, special equipment is used: a sewer cleaning machine.
The operation of such units is as follows: a special rotating cable with various types of nozzles at the end is inserted into the sewer pipe.
The working surfaces of the nozzles crush blockages, cut off or grind internal growths. As an option, pipes are cleaned using a thin stream of water, which is fed through a sewer cleaning hose under significant pressure. A sewer cleaning machine with this operating principle is called hydrodynamic. When working with equipment, various chemicals are often added to the water tank, which facilitate hydrodynamic cleaning of sewer pipes. When cleaning work is not carried out, a cable or hose is wound on a drum.
There is also a sectional version of the cable. The machine is powered by an engine, electric or gasoline. There is equipment that can operate on both fuel and electricity. Some models are supplied with batteries.
Distinctive features of high-quality cleaning units
How do you know how good a drain cleaner is?
To do this, you need to pay attention to several parameters:
Robust supporting frame. The drum with cable (hose), motor and water tank, depending on the model of the machine, can weigh quite a lot. Wheels. Drain cleaning equipment often needs to be moved, especially in commercial applications.
Models that are relatively light in weight are usually not equipped with wheels, but then they should have special handles for easy carrying. Additional stops. Running the motor and pulling the cable/hose puts a load on the power unit. Low stability and excessive vibrations will inevitably reduce the quality of work and service life of the equipment.
Some technical and other characteristics require special attention.
It is important to calculate in advance what diameter pipes you will have to work with. The length of the cable is another important parameter. A professional sewer pipe cleaning machine can be used in sewers with a pipeline diameter of up to six hundred millimeters, and a cable length of up to a hundred meters or more.
The number and type of cable attachments are determined by the model, as well as the potential problems that are supposed to be solved. The most careful approach to this issue is needed when you plan to work with pipes of various diameters.
After clearing the blockage, all foreign particles usually remain inside the pipes and are removed by subsequent flushing.
But there is an alternative here too. Some sewer pipe cleaning machines are additionally equipped with suction devices. In this case, the debris is removed from the cleaned section of the pipeline, rather than sent on a further “journey” with some risk of forming a new blockage later.
Work and result
- To clean a problem area of the sewer, the operator of the cleaning machine places the unit on a flat surface, selects and installs the nozzle on the cable or hose. Then the equipment is turned on (started) and the cleaning work begins. If necessary, the technician moves the cable/hose deeper into the pipe. With significant resistance, it becomes clear that the nozzles have “met” a blockage, and then the operator slightly pulls the cable (hose) outward. Gradually moving forward, the nozzles remove layers of dirt and grease, salt and other build-ups. At the end of the work, wash all contaminated elements and the sewerage (if necessary).
When used correctly and carefully, the sewer cleaning machine copes well with its tasks for a long time without failures or breakdowns.
