Cleaning of internal sewerage

The entire indoor sewer system is cleaned, starting from sinks, sinks and toilets, including internal risers and ending with exits to inspection wells. We clean internal sewage systems in residential buildings, business centers (offices), commercial and industrial facilities or industrial premises (workshops, factories).

Any blockage in the sewer will be removed, and the pipes will be cleared of years of contamination. Call 24 hours a day, 7 days a week!

Preventing sewer blockages

Even with proper operation of the system, various types of deposits accumulate inside the drainage pipelines.
Their nature depends on many factors: fat, protein, textile deposits, sand, soil, clay, oil products, silt, etc. However, in practice there are also stones, bricks, crushed stone, glass and plastic, sprouted roots, concrete. Over time, the amount of pollution increases, the capacity of the sewer network decreases and there is a risk of an emergency and sewer blockages.

Often, system owners and users are not even aware of the presence of serious deposits in sewerage pipelines. Unfortunately, in the future this inevitably leads to blockage and, as a consequence, to:

overflowing wells;
disruption of production operations, up to a complete stop (accordingly, this leads to financial unforeseen losses and damages);
violation of the tightness of sewer pipeline networks, their damage and destruction;
release and ingress of environmentally polluting wastewater into the ground;
violation of environmental safety, imposition of penalties by inspection authorities;
the appearance of unpleasant odors and flooding of premises with sewage.

All these unpleasant consequences can be prevented by performing regular work on comprehensive sewer flushing and timely diagnostics of the condition of pipelines. It is worth noting that the cost of work when removing serious deposits is sometimes several times higher than the cost of regular maintenance of sewer systems and preventive flushing of sewer pipes.

There is a special diagnostics division. It is a mobile laboratory with modern equipment designed to perform tasks to determine the condition of the internal and external sewer network.
Our specialists carry out a free visit and assess the need for preventive maintenance. Based on the results of the network survey, a service proposal is issued indicating a detailed description of the scope of work and recommendations on the regularity of their implementation, taking into account the specifics of operation.

During preventive work on sewerage flushing, the cavity of the pipelines of drainage networks is cleaned, the washed sediments are disposed of at special landfills, a video inspection is carried out and the condition of sections of the system is assessed. If a violation of the integrity of sewerage network pipelines is detected, an appropriate conclusion will be issued with recommendations for eliminating the identified defects.

Methods for cleaning drains

There are three main ways to get rid of blockages in sewer pipes:

Hydrodynamic method

This method is characterized by high productivity and is applicable to all sewer systems: stormwater, domestic, industrial and drainage. This method uses specialized equipment to clear drains and blockages in pipes. Each includes: a high-pressure pump, its own engine or a drive from a car engine, a hose on a drum, a control panel, a pressure regulator, pressure gauges and sensors, a water purification filter, and a set of washing nozzles.

Thermo-chemical method

It is carried out by specialized hydrodynamic installations using special chemical reagents and exposure to jets of hot water with high pressure (steaming). Chemical reagents for grease removal ensure its effective dissolution and removal from the surface of sewer pipelines. The chemical method of sewer cleaning is effective for sewer pipes with a diameter of 50 mm or more. This method has minimal impact on the pipelines of sewer systems and networks, ensuring the integrity and tightness of the system is maintained.

Mechanical method

The mechanical method of cleaning sewer pipes is used to eliminate complex emergency blockages in sewer networks. The method of mechanical sewerage cleaning is one of the most common; the work involves the use of special rotary units. The main component of the installation is a long plumbing cable that is directed into the pipeline. A special nozzle is installed at the end of the cable; as it moves through the pipeline, its rotation is ensured by an electric or gasoline engine.

Technologies for cleaning external sewerage

Cleaning (flushing) of external sewerage is carried out using a hydrodynamic method. The technology allows you to clean pipes from deposits and restore the original diameter of the system.

To carry out the work, we use a sewer washing machine, or a set of equipment consisting of a sewer washing machine and a sludge sucker. The need to use a suction pump depends on the volume of sediment in pipes and wells. The amount of sediment in pipelines of different diameters with the same length can differ many times.

Method #2 - thermochemical and thermal cleaning

An option for hydraulic cleaning can be considered thermal sewer cleaning. In this case, water is supplied to the pipeline under pressure, heated to a temperature of 95-120C. Hot liquid dissolves hard fat deposits more effectively and quickly. Thermal cleaning is also very popular in early spring or winter, when it is necessary to clear storm water or any other sewer system from freezing. The only drawback of the method is the inability to use it to work with pipes made of polypropylene and polyvinyl chloride.

Chemical cleaning is another common method used for sewer systems. Its essence lies in converting compacted sediment and sludge into a solution state and subsequent removal of contamination. For these purposes, certified industrial cleaning products are used. For the best effect, they are foamed using special equipment.

For professional sewer cleaning, special preparations are used, the cost of which is quite high.

Along with organic and inorganic acids, the cleaning composition also includes surfactants and surfactants. They make it possible to concentrate the effects of drugs and make it possible to obtain an additional positive effect of mechanical action during the collapse of foam segments. During the chemical cleaning process, substances that disinfect the pipeline are also used. In some cases, thermochemical cleaning, which combines chemical and thermal methods, is especially effective. It should be noted that the cost of chemical cleaning products is quite high, so this method is not always used.

Equipment

There are special hydrodynamic machines for flushing sewer networks; there are two types:

installed on trucks and used exclusively for flushing external communications;
portable small-sized units transported in cars;

Moscow and Moscow Region We provide services in Moscow and the region

Employees More than 200 employees with experience

Specialist. machinery 70 units of transport and equipment

Types of equipment and attachments

Household appliances are portable, electric, single-phase, designed to operate from a 220 V network. More powerful industrial equipment is connected to a three-phase network or installed on a car chassis and powered by its engine.

There are also models that run on propane gas. Electrical equipment is used to flush internal sewerage. Gasoline and propane machines are suitable for washing external communications where there is no possibility of connecting to the electrical network.

Nozzles are divided into the following types:

Punchy type. For breaking through tight traffic jams.
Bottom. They are used when it is necessary to remove significant deposits of silt, sand and mud.
Chain carousels. Remove debris, plant roots and other objects.
Rotary type. Used to remove fat deposits.
Universal nozzles. For regular flushing of the sewer system from other types of blockages.

Tips for choosing

A hydraulic cleaning machine must be selected according to the following indicators:

Water pump performance. For hydroflushing small-diameter pipes (up to 110 mm) of sewerage in private houses, storm canals, and sewer lines in an apartment, a device with a water flow rate of 10–12 liters per minute is suitable.
Maximum operating pressure injected into the pipe.
Engine's type. The choice of motor depends on the availability of the energy source. If it is possible to connect to the electrical network, then it is better to buy a device with an electric motor, otherwise - with a gasoline or propane motor.
Hose length. To wash long routes, you need professional installations with a hose length of 30 m or more. For household mini-washes, the hose length is 15 meters.
Engine power. The larger it is, the more powerful the pump on the installation will be. Such equipment can flush larger diameter pipes.

We work with objects in Moscow and the Moscow region

During our work, our company has accumulated vast experience in cleaning sewers in organizations in Moscow and the Moscow region. We are ready to work in the most difficult conditions, carrying out a whole range of activities on sewerage networks in various sectors of the economy. Letters of gratitude from clients are the best confirmation of our conscientious approach to solving assigned tasks.

Hotels, boarding houses, sanatoriums, holiday homes

In hotels and canteens, restaurants and cafes located in them, compliance with sanitary standards and rules is a necessary condition for normal operation. Maintaining sewerage networks in a condition that meets the requirements of the SES is an important task. For example, the Engineering Service group of companies uses a combination of hydrodynamic, hydrochemical and thermal cleaning technologies to remove grease and other deposits in sewer networks in Marriott hotels . This not only removes all deposits, but also disinfects the sewer system and eliminates unpleasant odors.

Athletic facilities

When holding various public events, due to the large number of people, it is necessary to maintain sewerage networks at sports facilities and stadiums in appropriate condition. For example, at the Lokomotiv stadium, in addition to comprehensive cleaning of the household sewerage network, the Engineering Service Group of Companies carries out cleaning of the sewer pressure station (SPS). Hydrodynamic, hydrochemical and thermal technologies for cleaning sewer networks, used by the Engineering Service Group of Companies, ensure reliable and safe operation of these networks.

Transport companies

Due to emissions of fuels and lubricants at motor transport enterprises, as well as mud and sand deposits in sewer networks, it is advisable to use a comprehensive technology for cleaning sewer networks. All waste (oil sludge, sludge) must be removed and disposed of in a timely manner, avoiding overflow of treatment facilities. Thus, working with ADMB-Yug LLC, we transport generated waste to the landfill several times a year, ensuring uninterrupted operation of the enterprise.

Embassies and representative offices

Embassies and missions, among other things, have kitchens and compliance with sanitary standards and rules is a necessary condition for normal operation. Maintaining sewerage networks in a condition that meets the requirements of the SES is an important task. For example, to remove grease and other deposits in the sewer networks in the building of the Chinese Embassy in Moscow, we used the following cleaning technologies in combination: hydrodynamic, hydrochemical and thermal.

Medical institutions

Using the technology developed by the Engineering Service Group of Companies, aqueous solutions of chemical reagents are used, certified and approved for use by the Ministry of Health of the Russian Federation. At the Russian Children's Clinical Hospital (RDCH), with the help of equipment and specialists from the Engineering Service Group of Companies, complex cleaning of storm and drainage sewer systems is carried out. All debris is mechanically removed, and pipelines, as well as the walls and trays of wells, are washed using the hydrodynamic method. Such cleaning ensures uninterrupted operation of sewer networks for a long period.

Waste incineration plants

The experience of the Engineering Service Group of Companies shows that the domestic sewage network at waste incineration enterprises is contaminated with fat and mud deposits and waste. In this case, it is necessary to clean this network at least once a quarter (four times a year) or even more often. This is due to a fairly large production waste output. This frequency of cleaning fully ensures compliance with sanitary standards and regulations, as well as the efficiency of sewerage networks. For example, the Engineering Service Group of Companies used the following cleaning technologies in a complex of the State Unitary Enterprise Ecotekhprom At the same time, not only all deposits were eliminated, but also the sewage system was disinfected and unpleasant odors were destroyed.

And in other areas of the economy:

Industrial enterprises
Shopping and entertainment complexes
Cinemas, theaters, museums and concert halls
Catering
Business centers
Department of Housing and Utilities

The principle of hydrodynamic cleaning

It should be noted that the hydrodynamic cleaning method is one of the most effective and safe. It is successfully used for cleaning not only sewers, but also pipelines for other purposes - water supply, heating systems, etc.

The essence of the method is the impact on deposits located on the walls of pipes with a stream of water supplied under pressure. Water is supplied through special nozzles for cleaning drains. Such nozzles can have a variety of shapes, and each of the modifications used is used to solve specific problems.

The nozzles are put on a flexible hose for cleaning the sewer, and the forward movement of this structure is ensured by jet thrust, which is created by high pressure of water coming out with high pressure from the holes located on the back of the nozzle. These jets effectively remove various sediments and contaminants located on the pipe walls.

Advice! The hydrodynamic cleaning method is suitable for pipes made from a wide variety of materials. Moreover, a pipeline cleaned using this method is less susceptible to re-contamination, since the pipeline acquires the ability to self-clean, which is characteristic of new pipes.
