Usually in a private house there is no possibility of connecting to the central sewage system, so the problem of removing accumulated drains from the cesspool becomes very acute. Even in private houses built on the outskirts of the city, it is not always possible to connect to the central sewerage system due to their great remoteness, and outside the city in cottage, dacha villages it is generally not realistic. Therefore, to deal with the arrangement autonomous sewerage it is up to the owners to control the degree of filling the cesspool and to clean it in a timely manner.
Before you start cleaning the pit, you need to figure out how this can be done. Most the simplest option, but more expensive because this service will cost a certain amount, this is a call to a specialized company to order a sewage machine. When placing an order, do not hesitate to check the availability of a certificate, which will avoid trouble if the drains from your cesspool are discharged in the wrong place.
If the cesspool is small, since the volumes of the drains themselves are small and at the same time irregular, for example, a family of 3 people comes to the dacha exclusively on weekends, then pump out cesspool you can independently, by your own means. Advice! For pumping, it is better to separately purchase a specialized pump. If the volumes of the pit or septic tank are significant, then the decision to independently clean them of drains will not be correct, it is better to immediately call special sewage equipment.
Self-cleaning of the cesspool
In the case of self-cleaning of the pit, you need to prepare, because you will need:
Usually, this problem is typical for plastic cesspools with limited internal volume. The modern design of the pumps, due to the presence of float level sensors, allows them to operate in an automatic on / off mode. Having reached the upper float, the drains raise it, and the pump turns on, after pumping out the drains, when their level reaches the lower float, the pump turns off.
Pit cleaning without a pump
If the pit has a small volume, then you can try to clean it in the old-fashioned way - to scoop out the drains with a bucket. To do this, you need to prepare:
- special clothing, preferably tightly buttoned;
- good respirator;
- container for removal of sewage;
- transport.
But this method is associated with certain difficulties, for example, it is dangerous for the respiratory system, after going through which many people prefer to spend money and call a flusher.
Modern ways of pumping out cesspools
In order to ensure the unhindered pumping of wastewater by a sewage truck, it is necessary to provide for the possibility of an unobstructed entrance for it, and it is better to entrust all the work to specialists. In addition, it is necessary to provide for the presence of a water source, power supply nearby. A more modern method of cleaning is the use of biological products, which contain microorganisms (bacteria). They are able to practically completely process all waste, especially of biological origin, in the effluent.
As a result of processing, the splitting of bio-contaminants by microorganisms into soluble fractions, biogas is released. Through ventilation pipe it is discharged into the atmosphere, and the soluble fractions facilitate the process of pumping out the effluents, with practically no smell. The complexity of the use of bio-purification preparations lies in their correct selection, depending on the composition of the effluent. Therefore, the question - what to fall asleep in the cesspool is very relevant. First of all, these can be universal preparations intended for use in all types of effluents. In addition, there are preparations for greasy drains or the winter period of operation, and others. Having poured the preparation into the pit, you can be sure that the self-cleaning process will continue even after pumping out the effluents, since some of the microorganisms will certainly remain in the pit.
Elimination of breakage defects of the cesspool
During the pumping process, it may be found that the pit walls need repair.
- Repairs brick wall consists in eliminating the problem by concreting, for which outside, opposite the defective place, you will have to dig out the soil, or install a new concrete block.
- A lift is required to repair a plastic container.
- Cesspool from iron concrete rings it cannot be easily repaired, since the setting of concrete with concrete base rings are prevented by a layer of fatty deposits. You have to clean everything up well.
Council. If the bottom of an old pit without a bottom is so sealed, silted up that it cannot be cleaned and the water has ceased to be absorbed into the soil, then another hole can be dug nearby. By connecting them with an overflow, you get a two-chamber septic tank, which, if properly used, can serve over 20 years.

The sewage system of a private house in the overwhelming majority of cases cannot be connected to the central highway, therefore the owners are limited to arranging receiving (storage) tanks (septic tanks, cesspools, sewer wells) on their site. The peculiarity of their functioning lies in the fact that during operation it is necessary to monitor the level of filling.
To ensure the smooth operation of the sewer system, professionals advise you to clean wells, septic tanks and cesspools at a certain frequency, which is determined by the type of system. Note that even a septic tank without pumping (automatic cleaning station) also needs to be pumped out, just its frequency is much less (every 5-7 years).
The easiest and most inexpensive way to equip a sewage wastewater receiver is to install a septic tank, but it is installed on sites that are being built up relatively recently, the owners of older country houses or summer cottages have a cesspool on their site.
Note. Currently, the construction of cesspools is prohibited at the legislative level, as an environmentally unsafe facility.
Still working principle single chamber septic tank and a cesspool in many ways. Accordingly, the pumping of septic tanks and cesspools is performed according to the same scenario.
How to pump out a septic tank and a cesspool
All the ways and methods by which you can empty the storage tank for the sewage system (septic tank or cesspool) are divided into three types:
1. Automatic pumping of septic tanks and cesspools
To carry out the work, special equipment is involved - a sewage truck equipped with a spacious tank (allows you to take out all the waste at one time), a hose and a pump. Pumping methods will differ depending on the type of pump:
- sludge sucker... A cheap and effective procedure that allows not only to eliminate the accumulated runoff, but also to remove bottom silt together with a part of the soil (depth up to 1 m.). This will restore the absorbency of the soil at the bottom of the sump. Note that it is possible to pump out the cesspool, which is simply dug in the ground, without strengthening the walls (summer cottage), only with a sludge pump;
- hydrodynamic cleaning... The technological feature is the ability to additionally clean the walls of the septic tank from formations and pump out its contents completely;
- vacuum pumping... Using a vacuum pump allows you to pump out a septic tank in a matter of minutes, without any dirty work. Among the presented methods, this is the most expensive, but the only one, after which there is no smell and dirt.
The cost of services of a sewer truck is determined by many factors, the key of which can be considered the remoteness of the object and the volume of pumped out wastewater. The order of prices is shown in the table
Note. The undoubted advantage, which is noted by all users, is that the use of special equipment allows you not to worry about the disposal of the drained waste.
2. Chemical or biological pumping of septic tanks and cesspools
Chemical treatment consists in the fact that special chemical reagents are poured into the storage tank for the sewage system, which affect the wastewater with the course of oxidation and neutralization reactions. This method is used as a preliminary or final stage before biological purification.
Biological purification of a septic tank is the use of biogranules (tablets, powder) that reduce the density of waste.
Note that if these methods are applied, a cesspool without pumping out will be quite functional. But, only under the following conditions:
- a cesspool was dug in the country, which is used periodically;
- it is intended only for faeces or the volume of waste water is small;
- the pit has a fairly large volume and, importantly, a large bottom area, which will increase the area for water to flow into the soil.
If these conditions are not met, you will still have to do pumping, and the use of chemical and biological agents will only delay this procedure.
3. Mechanical pumping of septic tanks and cesspools
The group of mechanized pumping methods combines two methods:
- manual "old-fashioned"... Involves cleaning a cesspool with a bucket with a rope. This method is used extremely rarely, because this procedure is not very pleasant, contamination of the site at the cleaning site is not excluded, and the raised drains need to be put somewhere;
- using a pump... The pump for pumping out a septic tank becomes the optimal compromise between the unwillingness to do the work manually and pay for calling the sewer truck.
Pumps for pumping out cesspools and septic tanks
There are three types of sewer pumping pumps:
1. Surface (horizontal) pump
It is installed near the septic tank, and only the sleeve is inserted into the septic tank. Allows to pump out waste water high temperature, however, without the presence of solid components (no more than 5 mm).
Surface pumps are distinguished by:
- mobility (dismantled after pumping out and can be used to perform work on pumping out the next tank);
- light weight;
- ease of installation;
- the presence of a grinder;
- the possibility of air cooling, which allows to extend the life of the motor;
- the lowest cost of the pump among other varieties.
Users note that the number of disadvantages outweighs the advantages, so the pump has not gained popularity. Among the cons:
- low power;
- immersion depth restrictions (up to 8.5 lm);
- the unit is not protected from moisture;
- it is advisable to install a protective cover during operation in the cold season.
Nevertheless, when choosing a pump for pumping out a cesspool, more often everyone prefers a surface one.
2. Semi-submersible (vertical) pump
For pumping out, the pump is placed in the thickness of the drains so that the engine remains on the surface, and only the working part is placed in the reservoir.
Advantages:
- the pump is equipped with a float switch;
- no restrictions on hose length (pumping depth).
Disadvantages:
- no chopper. Therefore, it can only accept wastewater with a solid fraction not larger than 15-50 mm (determined by the pipe diameter).
3. Submersible pump
The most popular type of pump, despite its higher price.
Benefits:
- resistance to aggressive environment. Housing submersible pumps made of durable material that does not corrode: cast iron or steel;
- significant operating power - 40 kW (maximum);
- volume of wastewater pumped per hour - 400 cubic meters;
- height of rise of drains - 40 m.p .;
- equipped with a grinder;
- the presence of an automatic float starter, which allows you to automate the operation of the equipment.
One of the important conditions for the functioning of fecal pumps is periodic cleaning, which is performed every 3 months. under the condition of non-stop pumping (for example, part of the pressure line) and adding oil (every 2 thousand hours of operation).
Which pump to choose for pumping septic tanks and cesspools
The correct choice of a pump for pumping out sewage is based on the following factors:
- type of pump. Makes installation requirements;
- equipment size (important if the neck is narrow);
- maximum immersion depth;
- performance and other technical parameters;
- restrictions on temperature conditions, working environment;
- restrictions on the size of the accepted solid fractions;
- degree of automation: presence of a remote control, float sensor etc.;
- availability of guarantees for equipment and the possibility of service.
Among the well-known domestic brands are: Topas, Tver Dzhileks, Astra.
To understand the variety of brands of pumps, marking will help:
- numeric marking - pumps out only relatively clean waste water (up to 5 mm.);
- letter F - drains with a fraction of up to 30 mm;
- letter H - grinds waste of any fraction (within reasonable limits).
The cost of pumping equipment varies in a wide range (from 2 to 20 thousand rubles), depending on the type, manufacturer, country of origin and pump characteristics. The cost of foreign analogues is presented in the table
Installation of a pump for pumping out septic tanks and cesspools
Procedure:
- installation of guides on the walls of a septic tank (cesspool). Eliminates the possibility of a change in the pump tilt angle;
- installation of a branch pipe at the bottom of the pump (responsible for pumping out sewage) and a coupling, the task of which is to fix the pump on a gravel pad or the bottom of a septic tank;
- connecting the chain (cable) to the pump housing. With its help, the pump is submerged to the lowest possible point;
- connecting the pump to the power supply network.
During operation, the pump needs preventive checks and maintenance, which consists in flushing with clean water, checking the oil level, replacing the grinder.
