Let's take the most typical situation as an example. The cesspool is new, everything goes into the ground, and there is no need to pump it out at all. But a year passes, a second, a third. And suddenly, the pit begins to fill and demands to be pumped out.And you have to pump it out. At first less often, then more and more often. What to do? How can we return to the state of the pit, when everything went into the soil and there was no need to pump it out?
There is a simple solution. After the machine does its job, you need to pour the product into the hole Doctor Robik 509.
It is designed to eliminate long-standing problems with sewerage: it liquefies thick masses and dissolves fossils. At the same time it eliminates the smell. It even cleans out the pores in the soil, allowing liquid waste to easily seep into it. Gradually normal operation of the sewer or drainage system will be restored. After this you can pour the composition Doctor Robik 109, which will already maintain the cesspool or sewer in an acceptable condition. For a cesspool with a volume of about 3 cubic meters, you will need 1 bottle Doctors Robic 509. And then, after about a week, 1-2 bags of 109, which will work for 30-40 days.
Waste containing detergents. As a result, soap deposits and build-up accumulate on the pipes. They can be removed with the drug Doctor Robik 809. Usually, products based on living bacteria cannot cope with soap and powders, and even vice versa – they are “afraid” of them. But the enzymes included in composition 809 are not afraid of soap and foam. They easily clean the walls of pipes and cesspool tanks from soap deposits. All Dr. Robik products can be used together without restrictions. Therefore, to completely clean the pit from siltation and soapiness, you can Dr. Robik 509 and 809 pour at the same time. Doctor Robik's products are economical, effective and safe for the health of people, animals and plants. 
One of the most common problems among owners of sewerage tanks is their siltation. If you know what to do if it silts up cesspool, then eliminating this problem will not be difficult. Biological, chemical and mechanical means can be used as methods to combat this nuisance.
The most striking sign of siltation at the bottom of the cesspool is a decrease in the volume of the tank. Subsequently, the rate of filling of the waste tank increases, and the need for frequent pumping arises. The second “symptom” is the accumulation of fatty deposits on the walls. They also reduce the volume of runoff and interfere with the normal settling of waste.
Other signs of siltation:
Mechanical cleaning
It is also called the goldsmith method. To carry out this type of sludge removal, you need to prepare a fecal or drainage pump, a brush for cleaning the pit, a reservoir for pumping out liquid (you can dig an additional pit) and a hose of the required length (for immersing the pump).
Step by step instructions What to do if a sealed cesspool or septic tank has silted up:
If you don’t want to clean the sludge in the pit yourself, use the services of a vacuum cleaner. Most professional machines are equipped with suction pumps. This is a device designed to remove silt deposits.
You can watch the video below to see how the pit is pumped out using a sludge sucker:
Advantages of mechanical cleaning:
- You can do it yourself;
- Suitable for cleaning concrete, metal and stone structures;
- Affordable and highly effective.
Disadvantages of this method:
- Won't help get rid of unpleasant odor;
- Manual cleaning is not acceptable for plastic and open cesspools;
- There is no long-term effect.
Chemical cleaning
It is a universal way to get rid of sludge. Unlike mechanical, it is carried out exclusively independently, and, moreover, completely eliminates the problem of stench. To get rid of sludge using this method, compounds of nitrates, ammonium, acids or formaldehyde are used (rarely, because it is highly toxic).
Step-by-step instructions on how to clean a cesspool with chemicals:
- Selected the right type chemical compounds. Experts recommend using nitrate cleaners - they are the safest for environment and are applicable in open structures;
- The required amount of product is measured. Do not exceed the permissible concentration - this can poison the soil or harm workers during subsequent wastewater treatment;
- The compound is poured into the container, after which the pit is closed. For some time, active processes of liquefaction of sludge and solid particles (paper, soap residue, grease) will take place there. On average, it takes from 3 to 6 hours to completely dissolve waste (for a volume of up to 2 cubic meters);
- Liquid waste is pumped out using a drainage or sewage pump into a separate container or pit. If in the future you plan to use another cleaning option, then the pit is washed clean water.
This method is good for those who do not want to use vacuum cleaners. It is quite economical and easy to implement.
Advantages of chemical pit cleaning from sludge:
- Chemicals can be used even in winter. Even though the top of the drain will be frozen, the acids will still be able to dissolve it. For example, biological drugs do not work in such conditions;
- Eliminated immediately bad smell. In addition, it is neutralized for a long time even in the absence of chemical compounds;
- This is very cheap way get rid of sludge. For example, 1 liter of Brilliance reagent costs up to $7; 300 ml of this liquid is required to clean 1 cubic meter of feces.
Flaws:
- Cannot be used in plastic barrels and septic tanks of open design;
- Has cumulative effects. The more cleanings, the longer the problem of silting is absent;
- It is not advisable to use bioactivators for a long time after chemical reagents. Chemistry neutralizes bacteria, so if you decide to switch to bacterial cleaning, you will need to rinse the pit thoroughly.
Biological treatment
The most effective and in a safe way To get rid of sludge in a cesspool is to clean the drain with bacterial preparations. Their operating principle is very similar to chemical reagents, but they do not harm the environment and the waste material.
As bacteria, you can use anaerobic microorganisms (they live without oxygen) and aerobic microorganisms (they need fresh air). During their life cycle, they process sludge, solid fecal deposits and fats.
Step-by-step instructions for biological cleaning of a pit from sludge:
- The necessary bacteria are selected. It is recommended to use anaerobic for septic tanks and sealed containers, and aerobic for open drains. In addition, there are different forms of bacterial agents. Concentrated powders, granules, tablets and solutions. The easiest to use are powdered products;
- The required amount of bioactivator is poured into the pit. The cleaning process lasts from 3 to 10 days;
- After the period of bacteria action ends, liquid waste is pumped out of the pit. It is noteworthy that these wastewater do not require special disposal. They can be used as fertilizers or water for watering fields, vegetable gardens or orchards;
- The container is washed with clean water. If further permanent use of bacteria is planned, then a new portion of microorganisms can be immediately placed in the reservoir.
Doctor Robic (ROEBIC) and SANEX have gained great popularity among homeowners. They are safe for the environment and differ from their analogues in their affordable price.
Advantages biological method sludge cleaning:
- Safety;
- Can be used to eliminate the problem of siltation in open pits;
- Eliminates not only deposits, but also unpleasant odors;
- Liquid wastewater after bacterial exposure does not need to be disposed of in special ways.
Flaws:
- Cannot be used in the cold season;
- Very long cleaning period;
- Bacteria are much more expensive than chemical reagents.
Even simplest form sewer with cesspool can significantly increase the level of comfort suburban area. However, this solution has a significant disadvantage - the container for the accumulation and primary processing of wastewater requires periodic removal of the contents. Agree, cleaning of cesspools must be carried out according to the rules so that no damage is caused to the environment.
Owners of private houses and dachas not connected to centralized sewer networks, we offer scrupulously verified, systematized information about the methods and specifics of cleaning. With our help you can choose best option disposal of sewage accumulations and learn how to implement it.
A detailed description of the methods used in practice is based on personal experience household owners. The requirements of utility standards are taken into account. The information is confirmed by photo and video applications.
Modern summer residents and homeowners have three main ways to do this:
- removal of sewage by pumping;
- use of preparations for biological decomposition of waste;
- chemical cleaning.
When figuring out how to effectively clean a cesspool, you should consider the specifics of using each of these methods. Depending on the situation, only one of them may be needed, but often it is necessary to carry out cleaning activities in combination. For example, after using biological drugs, additional pumping of sewage may be necessary.
When should cleanup activities begin? The work strategy should be thought through at the stage of creating a sewerage system, for example, by providing access roads for a sewer truck.
There is no need to wait until the drains fill the last cubic centimeter of the container. Excessive filling of the cesspool increases the likelihood of contamination of the area several times. If two-thirds of the tank is occupied by wastewater, it is time to reduce its level using available means.
Method #1 - emptying and pumping out the cesspool
If desired, the cesspool can even be cleaned manually, using an ordinary bucket on a rope. Owners of small summer cottages do just that. This work is extremely unpleasant and requires preparation. First, you should wear a protective suit or other clothing that you don’t mind getting dirty. This is necessary in order to protect the skin, the drains can be quite aggressive.
For mechanical cleaning of cesspools, special machines are used - suction pumps, which pump out the contents of the container and take it away for disposal.
Then you need to take care of protecting the respiratory tract, and it’s not just the characteristic stench. The fumes emanating from the sewer contain methane, the inhalation of which is extremely dangerous for humans. For the same reason, it is not recommended to carry out cleaning work alone, especially if work is planned inside the cesspool.
If the one below becomes unconscious from the toxic fumes, a partner can help him. In addition to a protective suit and respirator, you need to wear high rubber boots or shoe covers, as well as gloves.
You will also need a sealed container into which the contents of the cesspool will be disposed of. Later, this sewage must be taken to the place designated for its disposal.
The distance between the sewer truck and the cesspool should be no more than four meters. This point should be considered when choosing a location for the sewer system, as well as during further redevelopment of the site
Manual cleaning is a long, dangerous and unpleasant task. If your budget allows, it is better to use a special one rather than a bucket to pump sewage into a container.
Things will go much faster, there will be significantly fewer dangerous contacts with a lot of wastewater. But in this case we must not forget about security measures.
To clean the cesspool with your own hands, you can use a fecal pump. This pump needs to be flushed periodically as it becomes clogged with solid waste.
It is much more convenient to clean the cesspool using specialized equipment, for example, a sludge sucker. This is a machine that drives up to the site and pumps out wastewater through a special wide hose.
The distance between the suction pump and the cleaning object should be no more than four meters. This technique does not service pits more than three meters deep, but such deep structures are usually not found.
For the sake of safety, when manually cleaning a cesspool, it is better to perform all procedures together: one works below, and the second insures it from above
Even when constructing a pit, you should take into account this nuance: vacuum cleaners charge not for the volume of pumped out waste, but for each visit. In order to reduce costs, it is necessary to calculate the volume of the cesspool so that a quantity of wastewater that is a multiple of the capacity of the suction pump is intended for pumping. At the same time, you need to remember that pumping begins if the pit is two-thirds full, and not “to capacity.”
Method #2 - biological decomposition of wastewater
The process of recycling wastewater using microorganisms is widely used in various septic tanks and VOCs industrial production. But today, even for cesspools, a line of biological products has been developed that can do what is not possible when emptying cesspools - reduce or completely eliminate the unpleasant odor characteristic of sewers.
Depending on the form of release of preparations for biological treatment, they may need to be preliminary preparation. Usually the granules or powder just need to be dissolved in a small amount of water
The sewage disposal truck leaves, and a suffocating sewer spirit hovers over the site for several more hours, or even days. The use of biological drugs significantly improves the situation.
To do this you need to select suitable remedy and use it according to the instructions. Available in the form of gels, liquids, powders, granules, etc.
Microorganisms decompose the contents of the sewer into water and environmentally neutral sludge. From the permeable pit, water flows into the surrounding soil, and silt gradually accumulates. Naturally, the degree of such purification is lower than that of high-tech VOCs; the water cannot be used for irrigation, and the sediment cannot be used as fertilizer. But the speed of filling the cesspool is reduced significantly.
Of course, the sediment from the sewerage structure itself will not go anywhere; it also needs to be removed or pumped out using the method described above using sewer trucks. There is one more important nuance– not all wastewater can be processed using bacteria.
Special preparations are intended for biological cleaning of cesspools. Some of them are designed to recycle toilet paper dissolved in drains
Inorganic waste entering the sewer accumulates at the bottom and reduces the volume free space V storage capacity. Aggressive household chemicals, such as those containing chlorine, can create an environment that is harmful to microorganisms. Owners of washing machines and dishwashers one should be careful in this regard.

Method #3 – use of chemicals
If biological treatment If it's just a holiday for the environment, then the use of chemicals can pose a threat.
To remove waste from cesspools, the following are most often used:
- formaldehyde preparations;
- nitrate oxidizers;
- ammonium salts.
Even those who are far from chemistry know that formaldehyde is a dangerous substance. Its only advantage is its relative low price. This drug is toxic and can cause cancer. For these reasons, formaldehyde is practically not used to clean cesspools.
Cleaners based on nitrate oxidizers are much safer in terms of safety. best characteristics. Their composition is close to the components of fertilizers of this type, i.e. at correct dosage If you follow the instructions, this cleaner is completely safe. These drugs are different at a high price, which is fully justified by its high efficiency.
Ammonium salts are an effective chemical for cleaning cesspools, but such chemicals must be used with caution in accordance with the instructions
When added to the sewer system, the drug effectively dilutes waste, while simultaneously neutralizing unpleasant odors. After the effect of the drug ends, the processed contents of the cesspool can be quickly pumped out and disposed of.
One more thing useful property nitrate cleaners is that their effectiveness does not decrease upon contact with even the most aggressive household chemicals. Products of this type are suitable for cleaning not only the pit, but also the entire sewer system.
There is currently no accurate data on how safe drugs based on ammonium salts are. Therefore, when using this product, like any aggressive chemical, you need to carefully study the instructions and follow them exactly.
The presence of chlorine-containing agents in wastewater may weaken the effect of using this drug, but according to reviews, it copes well with unpleasant odors.
Waiting until the septic tank is filled to the top is a bad strategy. Cleaning should begin when the amount of sewage is 60-70% of the container volume
When choosing a sewer cleaning method, you should take into account your specific situation. For example, if you need to clean a cesspool under a separate toilet, you should pay attention to products that can dissolve not only drains, but also toilet paper.

Solving the siltation problem
Siltation is a serious problem for both permeable and sealed cesspools. In the first case, the liquid part of the sediment will not be able to enter the ground due to the dense silt layer that covers the internal walls of the structure. In the second case, sewage will have to be pumped out more often, since deposits will reduce the volume of the container.
One of the signs that sludge is forming inside a cesspool is the appearance of a characteristic unpleasant odor - hydrogen sulfide vapor. When figuring out how to clean a silted cesspool, you must remember that in this case you need to do more than just neutralize the waste or pump out the contents.
If your cesspool fills up too quickly or often silts up, you may want to consider upgrading it with an additional container and overflow
All plaque should be removed from the walls and bottom of the container. To do this, use chemicals or methods chemical cleaning, but the most effective is often a combination of these methods. At mechanical cleaning First, the bulk of the sewage is pumped out. After this, you need to supply water under strong pressure using a hose into the container.
The inner surface of the cesspool is treated with a jet in such a way as to break up the silty sediment and dismember it into individual small particles. Processing is carried out until the container is filled by approximately 25%. After this, the contents are either sucked off and then disposed of.
To chemically clean a silted structure, chemical cleaners are used that are designed to dissolve solid inclusions - the nitrate oxidizers already described above. They usually also cope with silty deposits. After some time, all or almost all of the contents will become liquid and can be pumped out without problems.
It is worth noting that the use of chemicals will be much more expensive than emptying by pumping, but this operation is easier to perform and will take less time. In the process of physically removing sludge, you will have to put up with a large amount of dirt, which usually accompanies this procedure.
In cesspools without a bottom, you will also have to clean or update the sand and gravel filter located below. The safest thing to do would be to remove the entire contents of the filter and re-install the clean components: a layer of sand, crushed stone and/or gravel about 40 centimeters thick.
To prevent siltation of the cesspool, it is recommended to drain water from it to a filtration field. It is best to do this at the stage of creating the structure, but if desired, you can perform this operation later. To do this, you need to install a horizontal one at about half the height of the cesspool to drain liquid waste.
If the cesspool is silted, it should be immediately pumped out and the walls cleaned using a scraper or chemicals, for example, nitrate oxidizing agents
To install a filtration field, you need to excavate the soil to the level of laying the outlet pipe. A layer of agrofibre is laid down, and crushed stone is poured on top. A pipe coming out of the cesspool is laid on this “cushion”. The pipe must be perforated; you just need to make holes in it at equal distances.
Another layer of crushed stone is poured on top of the pipe, and then covered again with agrofibre. It turns out that the pipe is surrounded on all sides by filter materials. This will ensure rapid removal of liquid contents from the cesspool and its safe disposal in the soil.
If problems with the cesspool begin to occur more often, it makes sense to improve the operation of the structure accessible ways. Some arrange it, which functions like a septic tank. To do this, next to the existing container, they arrange another one, approximately the same.
The first container should be sealed, and the second should be permeable or without a bottom. It is possible to make the second container sealed, but then it is necessary to provide for the discharge of juices to the filtration field or to drainage well. The overflow between these two sections is installed with a slight slope in the upper third of the containers.
First, the wastewater will flow into the first compartment, where it will settle, solid waste will sink to the bottom, and the liquid component of the sewer content will overflow when it reaches the desired level.
The second compartment will receive mainly liquid waste, which will quickly move to the filtration field for further disposal. As a result, the pit will have to be cleaned much less frequently, and the likelihood of siltation of the structure will noticeably decrease.
Freezing of sewer pipes occurs most often due to flaws during installation. If this happens, the pipe needs to be heated to restore the sewer system.
IN winter period The drains in the cesspool may freeze, which will lead to problems in the operation of the sewer system. To correct the situation, the frozen mass must be thawed. Traditionally, or is used for this. If there is no power supply, make fires next to the frozen pit, use blowtorch etc.
For craftsmen who have at least a little experience working with electricians, another method of defrosting a cesspool is available - heating directly using electric current. A metal pin is driven into the middle of the frozen cesspool to approximately the freezing depth.
Then you need to take an electrical cable of a suitable length. Its end is stripped and connected to the pin, and 220V power is supplied to the opposite end.
It may take quite a lot of time to completely defrost the structure, sometimes you need to wait about a day, it all depends on the size of the pit. When performing this type of work, it is imperative to comply with electrical safety requirements, for example, use protective rubber gloves, shoes, etc.
If it is not the pit that freezes, but the one leading to it sewer pipe, this indicates flaws in the laying of communications, for example, the trench was not deep enough or there is no insulation. These problems can be corrected in the summer, but during cold weather, care should be taken to defrost the pipes.
For this you can also use electric current. At the end of the cable you need to strip a section equal to the circumference of the pipe. To calculate this value, you simply need to multiply the pipe diameter by 3.14, i.e. to the number “pi”.
The protected wire is then wound around the frozen pipe. Power is supplied to the cable; after a couple of hours of such heating, the contents of the pipe will melt and the operation of the sewer system will resume.
Conclusions and useful video on the topic
A practical option for cleaning a silted cesspool is presented in this video:
Here we demonstrate the procedure for pumping waste out of a cesspool using a fecal pump, which should be washed periodically:
The process and result of using a bioactivator to clean a cesspool can be seen in this video:
Although the cesspool is very simple option devices autonomous sewerage, it requires proper maintenance and timely cleaning. Modern means allow you to get rid of waste accumulated in a building quickly and efficiently.
Still have questions about cleaning cesspools? Or maybe you know others no less effective ways and have you already tried them in practice? Ask your questions and share your experience in the block located at the bottom of the article.
Silt is the sediment at the bottom of the pit. Its appearance is normal.
Sooner or later it must form. Another thing is that during the construction of the pit, you (or someone) could contribute to its early appearance by making mistakes in the design.
All walls and the bottom of the septic tank had to be sealed.
If the bottom was left “as is,” then this is already a well. In this case, to wastewater quicksand, soaked clay, etc. are added.
Now it's too late to blame anyone. Let's better figure it out together: what to do if the cesspool has silted up?
How do you know that this trouble has happened to the pit?
Here are a number of signs:
- The pit began to fill faster than before. More often it is necessary to pump out;
- A stench emanates from the pit;
- Fatty deposits are visible on the walls;
- At the bottom there is a layer of silt.
Cleaning methods
Let us conditionally divide the methods of dealing with sludge into independent ones and those involving the use of technology. Let’s immediately say that hiring equipment, although it costs money, is much simpler and more efficient. However, there are places where it is not so easy to call a sewer truck, so there are always “old-fashioned” methods.
Goldsmith method
For pumping, you can use a water pump (although it is not intended for this). Then install a mesh with 1-2 mm cells on the receiving funnel.
Water pump
The liquid is discharged into a hole previously dug nearby (there the liquid will be absorbed quite quickly and can be buried immediately). Or in a container that can be taken away.
After the liquid has been removed, what is not pumped out is removed from the bottom by a brave worker by hand using a bucket and rope.Semi-automatic for a small pit
If a car is accessible to you, and the pit is small (for example, made of tires), then you can make a pole with a cap and try to thoroughly mix the dense compacted silt with the liquid.Making the hat is at your discretion; it can resemble an oar or a disk attached perpendicularly, the main thing is that it holds well.
After everything has been mixed, we call a sewer truck. She will be able to suck out the liquefied sludge.
In the absence of a centralized sewerage system, the only way out is the construction cesspool. - the simplest and reliable choice. Step-by-step instructions for creating drain hole- read on our website.

And here you will learn about how to choose a dry closet for your dacha. Review of models, design and principle of operation, as well as reviews of dry closets.
Vacuum truck – water – vacuum truck
If the hole is too deep, or you don’t want to bother with a pole, you can get rid of the sludge by calling a specialist. technique twice. The first time she pumps out the liquid. Then we find a way to fill the hole with clean water (with the same sewer truck, fire truck, or our own powerful pump).
Pumping sludge from a drain using a sewer truck
Under the pressure of water, the sludge from the bottom is stirred, becomes loose, and now when cleaned again with a vacuum cleaner, it will be completely removed.
It is clear that calling the machine again is only necessary if the silt at the bottom is dense and compacted. But often the vacuum cleaners are powerful enough to cope with the task the first time.Bacteria
Nowadays they produce special biological products for cleaning cesspools. Microorganisms clean the walls of septic tanks and pipes, soften sludge, and “digest” waste, leaving behind water, mineral sediment and carbon dioxide.
Cleaning a septic tank with the biological product "Microzim"
The advantages of the method are that:
- Easy to implement;
- Does not harm the environment;
- Eliminates unpleasant odors.
On the package you will find instructions on what and how to do.
If the hatch on your pit closes tightly, be careful when purchasing: if it says that the bacteria are aerobic, it means they need fresh air. In a sealed septic tank they will quickly die.Bacteria also have disadvantages. Like any living creature, they are whimsical:
- They don't like bleach, powders or detergents;
- If t is below 0 o C, or above +40 o C, the organisms die;
- They also die from “old age” - the colony needs to be periodically replenished.
Chemicals
In winter you can use chemicals. The safest among them are nitrate oxidizers.
If you use nitrate fertilizers in your garden, then this reagent will not cause you any concern.
The product will liquefy the sludge, just keep in mind that it should not be frozen.
Household chemical waste is not dangerous for the reagent, but its cost can be significant for some.
Previously, chemicals such as ammonium salts and formaldehyde were used. But they are toxic and have a bad effect on the environment.This unit will solve all your pit problems. It has more power than a conventional sewer truck, the depth with which it can handle is 16 m (as opposed to the 6 m of a sewer truck).
Heavy duty suction machine
Some suction pumps have nozzles that allow you to supply water under high pressure to cope with dense sludge.
Next steps
Now that the sludge has been pumped out, it all depends on how your pit is constructed. If it is sealed (the bottom is concrete, for example), then the work is over - you can continue to safely use the toilet.
If you left the bottom earthen or covered it with crushed stone, you need to make sure that in the near future the hole is not covered with clay again.
Sandy soils absorb moisture well. After cleaning, you can renew the gravel layer and use it. But to be honest, it's not very good good decision.The gravel will quickly become covered with silt again, and all procedures will have to be repeated.
Still, it would be better not to spare effort and money and pour concrete base(this is especially true for cesspools in loamy soils). This will help significantly delay the time for your next serious drain cleaning!

Among the most popular methods of cleaning structures are:
- manual cleaning using a bucket tied to a rope;
- pumping using a fecal pump;
- pumping out the pit using a sewer truck;
- biological treatment with biological products containing bacteria;
- chemical cleaning.
How to remove sludge from a cesspool using a bucket? To do this, you need to dilute the silt itself with water, take a bucket and a rope. You tie the bucket to a rope and lower it yourself to the bottom of the hole, scoop up the waste and all the liquid, and gradually pull it out. This is a rather unpleasant procedure, as disgusting aromas emanate from the device. Moreover, it is only possible if your hole has no bottom and is of shallow depth. After completing the procedure, be sure to fill the bottom with gravel to make subsequent cleaning of the bottom easier. Cleaning sludge from cesspools manually must be carried out in a special protective suit in order to avoid toxic gases entering the body.
How to clear sludge from a cesspool using a fecal pump? It's automated easy way. You will need a fecal or water pump, as well as a special sealed container for dumping waste. If you have an automatic pump, then you need to place it inside the pit, it will filter out the sewage and pump it out on its own as it fills. If it is semi-automatic, then you will need to control the pumping process. Liquen the liquid before pumping it out, pump it out and dispose of the waste. Rinse the hole with water and pump it out again. Fecal pump crushes large human waste.
How to clean a cesspool of sludge by turning to a sewer? This method does not involve intervention in cleaning on your part. You will need to find a cesspool company and order a cesspool pumping service. On a pre-selected day, a sludge removal machine will arrive, and with the help of a powerful vacuum pump(silt sucker) will clean the bottom of your structure. They will dispose of all pumped waste and flush the devices. We recommend that you definitely check the availability of documents that confirm the company’s ability to provide services for pumping out household waste from sewer systems, in order to confirm that company representatives must dispose of waste.
If you have sludge in a cesspool, then you can also clean it with the help of special biobacteria. There are special biological products for cleaning cesspools. It can be powder, liquid or tablets, all of which are added inside the structure. They reduce the mass of liquid and solid household waste by 80%; moreover, they interrupt and completely remove unpleasant odors from the area, prevent the appearance of sludge, and clean sewage pipes and the walls of the device from sludge. All this increases the service life of the installation. Moreover, these biological products are completely environmentally friendly and safe for adults, children and animals. Biological products contain special microorganisms (bacteria), which, when they enter the drains, begin to act and destroy the unpleasant odor and decompose sewage. For example, you can choose . These drugs are used in all seasons except winter, as they freeze and die. All features of the use of bacteria are indicated on back side packages with them. As a rule, you just need to throw them into the structure every 2-3 weeks and regularly wash the device with water.
How to get rid of sludge in a cesspool using chemicals? If your device silts up in winter, then instead of biological products you need to use chemical drug. For example, nitrate oxidizing agents. They are similar in composition to nitrate fertilizer and are considered environmentally friendly. As a result, the action produces a waste processing product that can be used as fertilizer. The use of formaldehyde and ammonium salts is strictly prohibited, as they are unsafe for humans due to toxicity.
Chemical reagents dilute sludge, eliminate unpleasant odors and reduce the volume of household waste. They work even in an aggressive environment if there is household chemical waste.
