Vacuum trucks: photos, characteristics

Everything you need to consider when choosing a sewer machine

In order to keep the city clean, today there are many types of municipal equipment.
One of these types of equipment is a sewer truck - a type of special equipment that is used where there is no centralized drainage system, for example, in private sectors. Having a sewer truck can be the start of your own business, since cleaning services for liquid household waste are popular. The purchase of such equipment will pay off in the first couple of years of use.

Sewage services: business plan

Have you decided to start this business? Where to begin? Now we'll tell you.

If you are not going to attract loans, you can do without a business plan. But it's better to make a sketch for yourself. It is necessary to take into account the costs:

• for the purchase of equipment;
• for its maintenance;
• for fuel, taking into account the distances to the nearest treatment facilities;
• payment for receiving wastewater;
• taxes.

Then you can find out how long it will take for everything to pay off and start generating income.

Is the sewage cleaning business profitable?

Of course it's beneficial.

• The main costs are fuel; payments to the recycling company for the waste are scanty.
• In rural areas there are practically no competitors.
• Prices for these services are not regulated; you can pledge up to 50% of your income. Moreover, no one thinks that they charge dearly for “dirty work.” If you do everything efficiently and are not rude, you don’t have to worry about reviews.

Legal issue and documents for sewage disposal business

It's easy to complete all the paperwork to get started. There are four steps to follow:

1. Contact the tax office and register yourself as a private entrepreneur. You can register a business, but this will require more time and money, and will then increase and complicate documentation.
2. Find the organization that is closest to you and disposes of household liquid waste. These will most likely be utility-owned wastewater treatment plants. If there are several options, then you need to focus on distances and prices. Transportation ten kilometers further usually eliminates the small difference in price.
3. Enter into an agreement with this organization to accept wastewater.
4. With these documents, contact the environmental authority, which will issue you a transportation permit. The stage should not cause complications; no additional requirements are imposed on carriers.

What it is?

A sewer truck (vacuum sewer truck) is a special vehicle that is designed for pumping and transporting sewage from sewers, settling tanks and cesspools. The pumping process itself occurs with the help of special intake hoses, as well as creating a vacuum in the tank of the machine itself.

The vacuum is created using a special vacuum pump (for example, “KO 503” or “KO 503v”). Actually, the name of the pumps determines the model of the sewer truck itself.

Equipment such as the GAZ sewer truck is found in almost every public utility. It is this brand of car that is so popular throughout Russia. And for large sewers, KAMAZ, MAZ and ZIL vehicles are used. Foreign analogues are also possible.

Business development strategies and service advertising

A business development strategy can go in two ways: increasing the quality of services provided and their quantity. Over time, it is worth considering the possibility of:

• renting a second car;
• expanding the customer base;
• organization of work seven days a week and at any time of the day.

Standing orders will be provided by contracts with a planned schedule of departures. Customer loyalty will increase as regular customers provide discounts, as well as willingness to come to the site to work upon immediate request.

They are not very willing to advertise sewer cleaning activities on television, but information can be conveyed to the target audience with the help of local newspapers, posting advertisements in private sectors and dacha communities. The inscriptions on your own sewer trucks are also effective and at the same time free advertising.

Types of vacuum cleaners

It is important that the tank capacity of the machine matches the volume that needs to be pumped out. The smaller the car, the cheaper it is to pump out. The minimum volume of a GAS tank is 2 m³. The compact machine will fit into narrow passages and gates. Its light weight allows it to be driven onto paving slabs. Can pump out the volume of approximately 1 concrete ring with a radius of 1.5 m.

The most common car is GAZ with a tank volume of 4 m³. The septic tank hatch should be located at a maximum distance of 16 m from the tank.

Almost all brands of sewage disposal machines are equipped with hoses 10-15 m long. But often this is not enough. Therefore, owners equip their equipment with additional hoses; the average hose length is 20-25 m. The longer the hose, the greater the power loss. If the distance from the pumped-out container to the intended location of the machine is more than 25 m, a vehicle with a high-performance vacuum pump is required.

An important characteristic of a sewer pumping machine is fuel consumption. Japanese diesel models are practical because they do not consume fuel during pumping. They are equipped with convenient, automatically collapsing hoses. The tank of such a machine is durable because it is galvanized on the inside.

The operating principle of sewage disposal equipment

Vacuum trucks are used for pumping waste products from cesspools, sewers and waste pipes, for pumping water during the repair of water pipelines, flushing pipes, wells, wells from sludge contamination, and transporting all types of non-flammable liquids. Vacuum machines are typically operated by utilities and industrial companies.

For example, for cleaning channels with a large amount of mud sediments, the accumulation of which leads to emergency situations. In large cities where there is a centralized sewerage system, vacuum machines are not so in demand. In summer cottages and in private sectors it is difficult to do without them.

With the formation of large cities with central sewerage, drainage on roads and many enterprises, a need arose for specialized equipment that could fulfill a number of requirements:

• pumping and removal of waste from enterprises;
• elimination of consequences after sewerage accidents;
• elimination of flooding on roads after precipitation, when drainage networks cannot cope;
• pumping out various grease and starch traps (relevant for catering);
• pumping wastewater, waste pits and septic tanks;

Sanitation

When planning to start a sewage disposal business, you also need to take into account the sanitary issue. Sewage is a dangerous liquid.

1. It contains a lot of nutrients; bacteria, including pathogenic ones, multiply quickly in them.
2. Pathogens and parasites of sick people and animals enter the sewer system.
3. There may also be technical ingredients that are toxic.

Therefore, when planning and running a septic tank pumping business, you need to take the sanitary issue especially seriously.

• Get a medical examination. If you have hired employees working for them, this is mandatory (the requirement is enshrined in law). Subsequently, do this annually, or better yet, more often.
• Be careful about personal hygiene rules.
• In addition to taking care of yourself, also take care of your technology. The machine and tank must be kept clean and periodically disinfected.

Sanitary inspection authorities, as a rule, have no questions about sewage disposal machines. The main thing is to fulfill the following requirements.

1. Have all the documents we talked about above.
2. Do not dump sewage in inappropriate places.
3. Avoid leaks while driving.
4. Do not pump out liquid when repairing the water supply system.

That's all we wanted to tell you about business using sewage disposal equipment. Work, benefit yourself and people.

Device

Special equipment for pumping waste is equipped with appropriate technological equipment. The design of the sewage disposal machine is as follows:

• storage tank or container for temporary storage and transportation of fecal fluid;
• driven vacuum pump;
• suction hose;
• piping system;
• technological control valve;
• receiving hatch;
• a signaling device indicating the operation of the fuse;
• electrical equipment.

Barrel capacity

The technological volume of the barrel of a sewer truck is determined by the parameters of the vehicle. In domestic models, the tank-reservoir can hold up to 12 m 3 of liquid, in imported ones - up to 16 m 3. Special equipment is selected depending on the tasks assigned.

There are the following sizes of sewer truck:

1. Small-sized models designed for private sewer septic tanks. The volume of the barrel in this case does not exceed 4 m3.
2. Capacious industrial vehicles with a tank volume of 10–12 m3 are used to clean wells from liquid fractions. They are more productive compared to their counterparts.
3. Sludge pumps are equipped with powerful equipment that allows you to pump out dense waste: liquid with dirt, silt, oil sludge or clay.

The latter, unlike standard sewage disposal machines, may have a water plunger pump, as well as a barrel of smaller capacity for flushing water.

Modifications of vacuum trucks

There is a variety of special equipment for pumping out waste. Vacuum tanks with liquid waste can be placed on the chassis of GAZ, KAMAZ, MAZ, ZIL, URAL, GAZELLE. Each brand differs in dimensions, characteristics, and load capacity.

GAZ cars are used wherever there is a need to dispose of liquids with a large amount of organic and inorganic impurities. The special equipment is easy to operate. It is equipped with a container with strong walls, which has an additional chemical coating that protects against corrosion.

1. GAZ 3307 allows you to install containers of different sizes on the chassis. The sewer truck is equipped with a special safety mechanism. When the tank is full, the motor turns off automatically. The presence of a four-way process valve and a built-in vacuum pump on the neck simplifies the task of waste disposal.

2. GAZ 3309 has similar characteristics to the GAZ 3307 series. The car is equipped with additional electrical equipment, including an automatic float valve and a safety alarm device that is activated when the tank is full.

3. GAZ 53 differs from previous models in a more capacious tank, which contains an additional compartment for clean water.

4. KAMAZ 65115 differs from other special-purpose vehicles by the presence of an all-wheel drive chassis and special hoses of different diameters.

The technical equipment, as well as the volume of the sewer truck, allow it to be used in hard-to-reach places.

According to traffic rules, the equipment is equipped with flashing lights.

Technical question

In order to start a business, you first need equipment. For beginners, at first glance, it seems that you need to buy a sewage disposal machine. But this is not always profitable, a new car is expensive, and there are almost no used equipment of this type on the secondary market. Several more options are possible.

We will equip the special vehicle ourselves

This is not very difficult, you will need a tank and the components listed below. Moreover, in the future, when repairing a machine, you will periodically have to replace one or another unit, right down to the tank.

In addition to the tank, you need:

1. Vacuum pump.
2. Cardans for connecting it to the transfer case;
3. safety valve;
4. desiccant;
5. muffler;
6. level indicator;
7. a set of taps for switching the pump from suction to pressure (for quick emptying and cleaning);
8. a shutter for blocking the suction hose;
9. Sleeves for pumping out sewage and connecting the pump to the barrel.
10. Fitting.

Alternatively, if the vehicle being converted was a dump truck and has a hydraulic pump, then the vacuum pump can be driven from a hydraulic motor.

How septic tanks are pumped over long distances

Using a container trailer instead of a car

In this case, the investment is less than when buying a sewer truck. But a tractor is needed to tow and drive the vacuum pump.

With a small number of customers, this approach is more profitable than working with a tanker truck. There is no pumping work, we provide other services, for example, transport or processing of personal plots.

There are also several options for purchasing capacity.

1. Buy ready-made. There are no special tanks produced for pumping out sewage, but there are agricultural machines of the MZhT type, they are designed for pumping out liquid farm runoff and applying it to the soil.

1. As in the case of a car, find a suitable container and mount the vacuum equipment on it yourself. The drive can be made either from the power take-off shaft (PTO) or from the hydraulic system through a hydraulic motor.

There are many options, so it’s easy to choose the one most suitable for you based on technical and financial capabilities.

A sewer truck based on the chassis of the legendary GAZ-53 car

Habitually using public amenities, we least of all think about the highways somewhere deep below us, along which everything washed away and drained moves, and about the wells where it accumulates. In fact, there is no miracle in the disappearance of waste products and all engineering communications, which are not usually discussed in polite society and at the table, are an ordinary technical system that requires repair and maintenance. Almost the main tool in this process is sewage disposal vehicles, created mainly on the basis of the chassis of GAZ cars of various modifications.

Vacuum truck as a business

The specificity of this lies in the need to purchase a car, without which it will be impossible to provide sewerage services. Therefore, the first thing you need to do after registering an individual entrepreneur is to select a suitable car and equip it taking into account the services provided.

You can rent a car, but it would be more profitable to purchase your own vehicle. When choosing a car, pay attention to fuel consumption. For example, GAZ cars that run on diesel fuel can consume up to 25 liters per 100 kilometers, taking into account the operation of the pump and the quality of the roads. The same cars, but running on gasoline, consume, under similar conditions, up to 35 liters. If you calculate the cost of gasoline and diesel fuel, you can come to the conclusion that purchasing a diesel car is more profitable from an economic point of view.

You will also need sewer pumps. They look something like this:

Advantages and disadvantages of the sewage disposal business

Let us highlight the main advantages of the sewage disposal business:

• Lack of competitors;
• High profit;
• Small labor costs.

But this business also has disadvantages that should also be taken into account:

• Considerable investments at the initial stage - for the purchase and re-equipment of cars;
• Psychological factor.

Most people, even having the financial opportunity to start a sewage disposal business, refuse this idea due to a preconceived opinion. Some consider such an activity shameful and undignified. Others think they will smell bad. It turns out that people, due to disgust and misconceptions, abandon profitable businesses.

But those people who, not afraid of public opinion, started a sewage disposal business note that in a day of work you can earn from 5 to 10 thousand rubles. In addition, thanks to modern technologies and good equipment, there is no contact with the pumped contents, and there is no unpleasant odor left after a working day.

In addition, if opportunities allow, you can do the work not yourself, but hire workers.

Additional Information

Before you start providing sewage disposal services, you need to familiarize yourself with all the rules governing this type of activity. For example, you must know exactly where you can drain the contents of tanks and where you cannot. If you dump contents in unauthorized areas, you may be fined a large amount.

Good luck to you!

Sewage truck based on GAZ chassis

Sewage disposal machines are used wherever there is a need to pump out liquids containing large amounts of organic and inorganic impurities - sand, silt, fecal matter. Actually, this determines the scope of their application:

• pumping out septic tanks of local sewage systems;
• cleaning drain systems of car washes, storm sewers;
• drainage of drainage and inspection wells, underground pipelines;
• drainage of drill holes and small reservoirs.

Design and principle of operation

The basis of the sewage disposal machine is a metal container that can be hermetically sealed. Since this special machine is faced with the task of pumping out not quite a liquid, but rather a suspension saturated with impurities, a vacuum pump is connected to this barrel. It creates a vacuum in the tank so great that through a wide corrugated receiving hose you can suck in, for example, all the water from the pond along with mud and crucian carp.

When a certain level of liquid in the tank is reached, a sensor is triggered and the engine is turned off. After this, the pump drive transfer case is turned off, and the sewage disposal truck can move to a place (special site) where the barrel is emptied and its contents are disposed of.

Photo of the GAZ-53 sewer truck

GAZ sewage disposal vehicles are based on the chassis of the GAZ 53, 3307 and 3309 models. The basis of their design is an all-welded metal tank with a hermetically sealed neck at the top, to which the vacuum pump line is connected, and an inlet pipe with a large-diameter four-way valve at the bottom. It can withstand high pressure; on the inside, a chemical-resistant coating is applied to its surface, which protects the metal from corrosion and makes it easier to maintain the tank. The outside is usually painted bright red or orange.

Basic equipment of sewer trucks

Tanks for vehicles based on the GAZ, ZIL, KAMAZ vehicles are made of rolled steel sheets 4 mm thick, with a volume from 3 to 12 m3. Imported sewage disposal machines can have capacities of up to 16 m3. An anti-corrosion coating is applied from the inside, and ribs are installed to prevent possible compression. The outside of the car is primed and painted red or orange.

Sludge sucker - device

The intake hose for a vacuum cleaner can be made of rubber with a fabric backing or soft PVC. It is made in the form of a rigid corrugated sleeve with soft ends for connection to metal pipes. The length and diameter of the intake hose depend on the power and performance of the pumping equipment. The manufacturer recommends a length of 4 to 15 m. A prerequisite is the presence of a metal cord made of wire.

If necessary, longer hoses are available for pumping septic tanks; additional hoses are attached to them. Their total maximum size cannot exceed 100 m. To clean cesspools, hoses with a diameter of 75–200 mm are used.

The operating principle of sewage disposal equipment

The technique works on this principle:

• The working hose is lowered into the waste pumping area.
• To move liquid inside the tank, a vacuum pump is turned on, which is powered by a machine engine. The operating time of the suction system depends on the size of the tank and averages from 4 to 12 minutes.
• When the tank is completely filled, the engine stops or a safety device is triggered - a special liquid level sensor built into the tank.
• After the fuse signal is given, the pump is automatically switched off.
• The removal of sewage is part of a set of measures for the improvement of populated areas, therefore, upon completion of the work, the car is sent to a recycling point, where emptying is carried out.

How profitable is it to run a sewage cleaning business?

The cost of draining and subsequent disposal of reinforced waste in municipal utilities (city Vodokanal) averages about 200 rubles. for 10 cubic meters m.

The price of vacuum cleaner services ranges from 600 to 1,200 rubles. for 1 cubic m. In addition to payment for drainage, the cost of these services includes costs for fuels and lubricants and equipment maintenance, driver’s wages, etc.

In general, sewage disposal activities can be characterized as a fairly profitable business. Carrying out 3 to 5 trips per day, a vacuum cleaner can bring in about 150,000 rubles per month. net profit. Moreover, a clear advantage of the business is that there will never be a shortage of clients, since waste is an inevitable consequence of human life.

What is a vacuum cleaner machine

Such transport is special equipment in the form of a chassis with attachments. A sewage disposal machine is used to drain swamps in which the process of rotting has begun, remove liquid from small reservoirs, waste from septic tanks, cesspools, and also to clean swamps. For these purposes, modern equipment is used, which creates a vacuum inside the transport tank. And the presence of a special window in it allows you to control the process of filling the container. Such equipment is installed on chassis from various manufacturers. In Russia, the use of KAMAZ, ZIL, and GAZ models is widespread, due to economic feasibility.

Machine structure

To ensure the performance of its functions, special equipment is installed on such a unit. As a result, special equipment consists of the following elements:

1. A transport container made in the form of a tank.
2. Technological crane used for control.
3. A vacuum pump, the operation of which is provided by the transfer case from the power plant.
4. Reception hatch.
5. Special self-expanding hose.
6. Electrical equipment.
7. A device that automatically turns off the pump or notifies the operator when the tank is full.

Operating principle of special equipment

The operation of such a unit is due to pumping liquid inside the tank using a vacuum pump. This technique works as follows:

1. First, the required vacuum cleaner is selected based on its dimensions and tank volume.
2. Upon arrival at the waste pumping site, a hose is installed and the system is connected.
3. Then the vacuum pump turns on and the tank is filled with pumped out liquid waste. After reaching the limit level, the distributor automatically turns off the pump or a special sound signal is given to the operator.
4. The vehicle transports the liquid in containers to the disposal site, where it is unloaded. When pumping out certain chemicals, additional precautions must be observed.

The volume of the tank used in the car depends on its technical parameters. Thus, in domestic models the capacity is limited to 12 m3 of liquid, while in imported versions it can be up to 16 m3. The choice of a suitable model of special equipment is determined by the assigned tasks. The following types of units are used:

1. Small-sized models, for example, based on a gazelle. They are used for pumping waste from septic tanks in private homes. Here the tank volume is no more than 4 m3.
2. Spacious options. Such models are industrial types, and the volume of the tank used is up to 12 m3. They are used to clean wells from various types of liquid fractions and have significantly higher productivity than the first models.
3. Silt suckers. Such units are equipped with the most powerful equipment, which makes it possible to pump out, among other things, dense waste in the form of dirt, oil slag, and sludge. For this purpose, special types of water pumps (plunger) are installed on such models and additionally use a small barrel with clean water used for flushing.
