Flushing of sewerage using hydrodynamic method in Moscow

send an application

The efficiency of a sewerage pipe system depends on many factors, the main one of which is the thickness of deposits on the inner surface of the pipes, which significantly reduce the useful cross-section of the pipeline, reducing its throughput. Because of this, there is a decrease in the productivity of the sewerage system and an increase in energy consumption at pumping stations. To prevent the formation of deposits, it is necessary to regularly flush the sewage system.

COST OF SEWER FLUSHING

You can find out the final cost by calling our specialists by phone.

The final cost of work is influenced by: length of the route; pipe diameter; burial depth; the presence of tie-ins and branches; accessibility of access to pipes.

Types of sewer blockages

Blockages form for various reasons. This may be the negligence of the owner, who regularly pours greasy waste and large particles of household garbage into the sewer, or the inevitable natural growth of deposits during operation.

It is customary to distinguish the following types of blockages:

• Mechanical. There was construction debris and other foreign objects in the sewer.
• Operational. Particles of food waste, grease, hair or other small particles gradually accumulate on the inner surface of the pipeline walls.
• Mineral. Rust and lime deposits. Rust can form a blockage exclusively in a metal pipeline, while limescale deposits can be deposited on any materials. The rate of growth of lime deposits directly depends on the quality of the water.

It is important! Cast iron drains are considered to be the most prone to blockages. The material of such a pipeline is porous, and particles of grease and dirt easily settle on it. Plastic pipelines are less susceptible to this unpleasant phenomenon.

ADVANTAGES OF HYDRODYNAMIC SEWER CLEANING

The main advantage of this method is complete cleaning of the pipeline. Thanks to the jets of water, even the most inaccessible areas are cleaned, and all dirt is completely washed out of the pipes. In this case, there are no threats to the integrity of the pipeline walls.

With the mechanical method, the blockage is only temporarily broken through, all the dirt remains in the pipe, forming another blockage after a short time. There is also the possibility of damage to the pipeline walls. Therefore, we consider this method as a separate one to be completely outdated and do not recommend using it as the main one.

This technology allows you to completely eliminate all deposits and blockages in pipes by exposing them to water under high pressure. For such sewer flushing, special equipment is used: sewer flushing machine VHT 150/100. A long hose with nozzles is lowered into the sewer pipe, after which water is supplied into it under high pressure - up to 350 atm. Due to the jet movement of water flows, the nozzles rotate in a circle and effectively clean the inner surface of the pipe with water jets.

The installation for hydrodynamic washing of sewer pipes is completely autonomous and does not require connection to the power supply network. The working fluid enters the nozzle through a special high-pressure hose. Due to its significant speed, water acts on deposits with high kinematic energy, quite sufficient for the reactive rotation of the nozzle and cutting off all deposits inside the pipe.

The efficiency of sewer flushing using this method is up to 99%. This method is optimally suited for working in Moscow with pipes of any diameter with the following deposits:

• lime;
• fat;
• silt;
• corrosion, etc.

To increase cleaning efficiency, various types of nozzles are used:

• universal type of nozzles for deposits of any type;
• punching nozzles to remove blockages;
• chain nozzles for deposits with high mechanical strength;
• bottom nozzles are optimal for removing sludge deposits;
• specialized nozzles for solving other specific problems.

Causes of blockages

There are two groups of causes of blockages:

• operational;
• technological.

The first group is a consequence of improper use of the system, the habit of throwing small debris, sand and crumbs of building materials into the toilet during repairs. The second group is the result of errors in the design or creation of sewers.

Operational reasons include:

• violations of technology when laying pipes, lack of a specified slope;
• foreign objects that are too large enter the system.

Technological violations leading to clogging:

• violation of the hydraulic operating mode of the system;
• long service life without cleaning.

Sewage pipelines are a non-pressure system designed to move wastewater by gravity. The lack of pressure reduces the speed of movement and increases the possibility of fatty organic components sticking to the pipe walls. Uninsulated cast iron pipes in old systems pose a particular danger in this regard. Their walls are rough, organic particles easily cling to irregularities and form clusters over areas of considerable length. As soon as a thin layer of organic matter forms, the rate of sludge adhesion begins to increase and in the final stage completely covers the cross-section of the pipe. If there are any protrusions, elevation changes or other obstacles, it is only a matter of time before a blockage occurs.

Sewer flushing

This process is the basis of all possible scenarios for the spread of layers; any initial cause provokes it to one degree or another. Only hydrodynamic cleaning of sewer pipes can reduce its intensity to the maximum extent and increase the operating time of the system until the next flushing.

WHERE IS SEWER WASHING CARRIED OUT?

We carry out hydrodynamic sewer cleaning in many establishments in Moscow.

Hotels and cafes

In such establishments, special attention is paid to compliance with all sanitary requirements. It is important to do regular cleaning, remove all blockages, including odors, and it is important not to damage the pipes so that there are no leaks, so this option for removing blockages is simply ideal. After which disinfection work is carried out.

Stadiums

Very large numbers of people gather here, so maintaining sewerage systems in proper condition is a very important task. We specialize in such complex objects. Ensuring their continuous operation, without incidents or accidents, is our task.

Transport organizations (STO)

Here, the main blockages are lubricant, gasoline-diesel, and mud deposits. To eliminate them, it is necessary to use an integrated approach to the problem. We specialize in such tasks, eliminating blockages of any complexity.

Enterprises

At large enterprises, deposits can be of any type, depending on the focus of production. To cope with them, you need an individual, comprehensive option that is ideal for a specific object. Our professional workers will easily find this option and provide the best sewer cleaning for factories, companies, etc.

This is not a complete list of institutions with whom we work; the entire list includes many more organizations. To clarify all questions and nuances of working with your object, please call. Our manager will answer all your questions and help you resolve any flushing issue.

Equipment and attachments - features of choice

There are several types of nozzles (nozzles) for hydrodynamic sewer flushing:

• rotating nozzles are designed to destroy heavily hardened sediment;
• punching – remove old blockages and air pockets;
• bottom - eliminate sand, silt, sludge. Suitable for cleaning wells and storm drains;
• chain (cutting) – for removing foreign objects and root blockages that have gotten into the pipes. Due to the ability to grind various substances, this option is optimal for the most neglected, compacted plugs;
• rotary – for cleaning the internal cavity of pipes from fatty deposits. They can also be used to clean storm drains;
• corner – for processing bending parts of the pipeline;
• universal ones can perform several functions.

Tip: You must have a universal nozzle in the kit, since in some cases it can be used instead of another one that is missing.

The design of the nozzles is generally the same, but the shape is different. The number of jets is also different - one central or several.

Types of nozzles for hydrodynamic cleaning

What to look for when choosing a device:

• cross-section of the pipeline for which the machine is designed. Household appliances clean pipes from 5 to 35 centimeters. Above 35 centimeters, an industrial gasoline installation on a wheelbase will be required;
• length of the route. The hose length starts from 15 meters. Professional devices have hoses of 30 meters or more;
• a household/semi-professional device can be portable or on wheels for ease of transportation. The choice depends on the conditions in which you will work.

Important: You must immediately select a hose of the required length. You can’t build it up; under pressure it will burst or the connection will come apart.

If you are going to buy equipment for permanent work, the choice depends on the future clientele:

• A portable mobile model is suitable for servicing apartments;
• for storm sewer systems in holiday villages or for cleaning main pipelines, a powerful installation on a vehicle chassis will be required.

The advantage of the former (usually electric) is compactness, noiselessness (equipped with a sound-insulating casing), ease of transportation (can be carried in the trunk of a car).

The advantages of the latter are high power and independence from electricity. Most often these are gasoline models that are powered by a car engine. Autonomy allows the equipment to be used in areas where electricity is absent or supplied intermittently.

Several popular semi-professional devices:

• HD 13/100 is an electric model with 2.3 kilowatts. Operates under a pressure of 100 atmospheres, water consumption - 13 liters, hose length - 30 meters, possible pipeline cross-section - 4-15 centimeters;
• HD 17/190 – electric, 5 kilowatts, 190 atmospheres, 17 liters, 40 meters, 4-20 centimeters;
• HD 19/180 – petrol, 6.5 l/s, 180 atmospheres, 19 liters, 40 meters, 4-20 centimeters;
• Ridgid KJ-1590 – electric, 2.2 kilowatts, 92 atmospheres, 15 liters, 20 meters, 5-15 centimeters;
• Ridgid KJ-2200 – petrol, 5.5 l/s, 150 atmospheres, 9 liters, 30 meters, 5-15 centimeters;
• Ridgid KJ-3000 – petrol, 13 l/s, 208 atmospheres, 15 liters, 60 meters, 5-20 centimeters;
• ECO 2221 – pipes up to 25 cm, hose length – 25 meters;
• PREUS B1515 – pipes up to 15 cm, hose – 15 meters;
• Poseidon VNA-B-210-10 – up to 15 cm, 15 meters.

Example of a sewer cleaning machine
For country needs, you can purchase a mini-car wash “KARCHER” or similar, with a pipe cleaning function. The sink can be used, among other things, for washing facades and other household purposes, so the purchase is justified. The device allows you to flush a pipeline 15 meters long.

The prices for mini-washes are not comparable with the cost of the above-mentioned devices:

• KARCHERK 5 Basic – from 16 thousand rubles;
• BOSCH Aquatak AQT 37-13 Plus – from 12;
• GREENWORKS GPWG2 – from 8 thousand;
• Sterwins 160 bar – from 13.

Compare:

• ECO – from 105 thousand;
• Preus – from 72;
• Poseidon – from 62.

A hose and a set of nozzles for a mini-wash will most likely have to be purchased separately; they are not included in the basic package. A kit for KARCHER pipes with a 15-meter hose will cost 5-6 thousand.

STAGES OF WORK

Cleaning procedure

How to flush sewer pipes using a hydrodynamic method (using the KARCHER installation as an example):

1. Select a nozzle and install it on the hose.
2. Insert the hose into the pipe about a meter. This can be done through the toilet, inspection hatch, or another opening.
3. Turn on the device. Hold the hose while working. It will move inside the pipeline.
4. After destroying the main blockage (this will be visible, the water will immediately begin to drain), make several back-and-forth movements with the hose to better flush the line.
5. Turn off the device, remove the hose.
6. Flush the pipeline with plenty of water to wash away any residual contamination.

Advantages of the hydrodynamic method of flushing sewer pipes

This method has many advantages, the main ones:

1. Guarantees the integrity of the pipe and the absence of mechanical defects.
2. High efficiency in cleaning pipes from blockages, sludge, old deposits and foreign bodies.
3. Low cost of cleaning.
4. Ensuring complete environmental safety due to the absence of chemicals harmful to the environment and people.
5. Can be carried out when laying pipes of any complexity.
6. Ability to carry out work even at sub-zero temperatures.

How to take care of your sewer

Cleaning of sewer pipes may be necessary if waste is disposed of in the sewer system: scraps, scraps, construction waste and glue, feminine hygiene items, fabric, thick paper, animal hair.
Due to improper operation of the sewer system, severe impassable blockages may occur. Trust the removal of blockages in your drains to specialists. In difficult cases, it may be necessary to dismantle the sewer pipes or even completely replace them. Therefore, for prevention, it is necessary to carry out cleanings every year to prevent the appearance of difficult-to-remove blockages.

What other methods are there for flushing sewer pipes?

Let's consider how else you can flush the system, besides the hydrodynamic method.

Temperature-chemical

It is carried out using a hydrodynamic cleaning installation, but at the same time it is combined with the use of active chemical mixtures and high temperatures of high-pressure water jets, the so-called steaming occurs. These additional chemicals The substances are good at destroying all deposits, for example fatty ones, completely dissolving them, then they are washed off with a stream of water and the pipeline is completely cleaned. This method is well suited for pipes larger than fifty mm in diameter. At the same time, the chem. the reagents do not interact with the wall material, therefore they remain completely intact, without any damage, their functionality is restored and their maximum efficiency is ensured.

Mechanical

This method is already outdated and is rarely used by us. This is due to the fact that its effectiveness is much less, the result is short-term. The method is to use a plumbing cable with a nozzle. The cable rotates electrically and the pipe is cleaned as it passes through the nozzle. The disadvantages include the fact that in this way it is not possible to clean hard-to-reach places; partial deposits will still remain in the pipe, the pipe will not be completely cleaned, therefore it will still be necessary to use hydrodynamics. We use this method only as a measure against complex blockages that need to be moved, then flushing is carried out using a hydrodynamic method.

How to determine the appearance of a blockage

The appearance of a blockage can be easily determined by a decrease in the rate of water flow. If you detect the threat of this blockage at the very beginning, you can delay its occurrence for some time. This is achieved in different ways.

Cleaning the sewer is possible using baking soda, boiling water, vinegar or household chemicals (although their action is based on the properties of the same soda). It is important to remember that household chemicals can damage the material of the sewer pipes themselves, which can lead to leaks.

OUR ADVANTAGES

Economic effect

Preventive measures are always aimed not only at maintaining the functionality in working order, but also reducing the financial costs of complete repairs.

Note! Regular sewer cleaning using hydrodynamics increases the service life of communications and equipment without major repairs by 15–20 years (especially with regular cleaning) and sharply reduces the number of unscheduled repairs.

Preventive flushing of communications is necessary for the following reasons:

• ensure the normal functioning of the drainage network, shut-off valves and pumping units;
• after timely hydrodynamic flushing, reduce the likelihood of emergency failures;
• Thanks to timely cleaning, reduce the cost of operating and repairing collectors;
• increase the permeability of communications;
• reduce hydraulic losses;
• restore the ability of sewer lines to self-clean.

Technological sequence of operations:

• determination of the amount and composition of sediment;
• preparing the object to be cleaned;
• deployment of the aggregate part;
• installation of pumping equipment and plugs;
• direct cleaning;
• collection and disposal of sediments using a suction pump;
• identification of hidden damage (pipeline leaks, damage to metal structures, depressurization of containers, etc.) and their elimination;
• commissioning of the facility to the customer.

REGION OF WORK ALSO INCLUDES:

Etc. We carry out work throughout the Moscow region.

Reminder on the correct use of sewerage

Despite the fact that every adult knows the purpose of the sewer system, often the result of its malfunction is the human factor. The confidence that everything will “slip” into the sewer gives the short-sighted resident a reason to dump anything into the system.

The main prevention against blockages for this reason is a reminder that under no circumstances should you throw into the sewer:

• large food debris and fats;
• construction garbage;
• paper, if it is not dissolvable toilet paper;
• thick paper towels;
• diapers, wet wipes and cotton swabs;
• pads and condoms;
• pet litter;
• adhesive plasters and dental floss.

It is necessary to firmly understand that a sewer is not a garbage chute.

Therefore, the temptation to quickly throw something that is no longer needed into the toilet, rather than into the trash can, and forget about it, must be countered by an understanding of the consequences that such actions will lead to, and which will soon remind of themselves.

Irresponsibility and negligence in the use of sewerage threatens problems not only for the culprits who committed negligence, but also for neighbors in the house

Living in a private house, you often encounter various domestic problems, in particular with sewerage. Either it gets clogged, or it becomes worse to leak, or the flush in the bathroom or kitchen is weak. It doesn’t work in the usual way like in an apartment, because... The sewage system in the house is autonomous and can clog in any area. Therefore, from time to time we have to order cleaning of pipes and their complete flushing, in order not to lead to an emergency situation, we carry out preventive maintenance once a year with the help of specialists from this company, it is relatively inexpensive, and we are satisfied with the quality of the work, thank you.

Pumping and disposal of fat from grease traps

A grease trap, just like a sewer, requires regular maintenance.
Catering enterprises, as well as food production enterprises such as meat processing plants, dairy plants, fat-and-oil plants and the like have a high concentration of fats in their wastewater. Insufficient wastewater treatment leads to the formation of fatty deposits on sewer pipes. To avoid emergency situations, such enterprises are required to be equipped with grease traps. This design helps filter out the grease, after which it enters a chamber where it is stored until it is removed.

A grease trap, just like a sewer, requires regular maintenance, in the absence of which there is an increased risk that the water will simply stop going down the drain, which will make the facility impossible to operate. Sanitary control services may impose penalties for this.

Pumping out and disposal of fat is impossible without the necessary license and documentation. Ecolife Group of Companies offers a wide range of services, including cleaning grease traps and disposal of fat deposits.
