How to clean a drain hole from silt. What to do if a cesspool or septic tank fills up quickly? Reasons for fast filling

Among the most popular cleaning methods of the structure are:

manual cleaning with a bucket that is tied to a rope;
pumping with a fecal pump;
pumping out the pit with a cesspool machine;
biological treatment with biological preparations containing bacteria;
chemical cleaning.

How to remove sludge from a cesspool with a bucket? To do this, it is necessary 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 pit, scoop up the waste and all the liquid, and so gradually pull it out. This is a rather unpleasant procedure, as disgusting aromas come from the device. Moreover, it is only possible if your pit is without a bottom and has a shallow depth. After completing the procedure, be sure to fill the bottom with gravel in order to facilitate subsequent cleaning of the bottom. Cleaning sludge from cesspools by hand must be carried out in a special protective suit in order to avoid the ingress of toxic gases into the body.

How to clean a cesspool of silt using a fecal pump? This is an automated, easy way. You will need a fecal or water pump, as well as a special sealed container for waste disposal. If you have an automatic pump, then you need to place it inside the pit, it will filter out sewage and pump it out on its own as it fills up. If semi-automatic, then you will need to control the pumping process. Liquefy the liquid before pumping it out, pump it out and dispose of the waste. Flush the hole with water and pump it out again. The fecal pump crushes large human waste.

How to clean the cesspool from silt by turning to the sewers? This method does not involve intervention in cleaning on your part. You will need to find a sewer company and order a cesspool pumping service. On a pre-selected day, an silo pump will arrive, they will clean the bottom of your structure with a powerful vacuum pump (silo pump). They will dispose of all pumped waste and wash the devices. We recommend that you be sure to check the availability of documents that confirm the company's ability to provide services for pumping household waste from sewer systems in order to confirm that the company's representatives will dispose of sewage without fail.

If you have sludge in the cesspool, then you can also clean it with the help of special biobacteria. There are special biological preparations for cleaning cesspools. It can be powder, liquid or tablets, all this is 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 site, prevent the appearance of sludge, clean the sewage pipes and walls of the device from sludge. All this increases the service life of the plant. Moreover, these biological preparations are completely environmentally friendly and safe for adults, children and animals. As part of biological products there are special microorganisms (bacteria), it is they, getting into the drains, that begin to act and destroy the unpleasant odor and decompose sewage. For example, you can choose . These drugs are used in all seasons, except for winter, as they freeze and die. All features of the use of bacteria are indicated on the back of the packages with them. As a rule, you just need to throw them into the structure every 2-3 weeks and wash the device regularly with water.

How to get rid of sludge in a cesspool using chemicals? If your device is silted up in winter, then instead of biological products you need to use a chemical preparation. For example, nitrate oxidizers. They are similar in composition to nitrate fertilizer and are considered environmentally friendly. As a result, a waste product is formed from the action, which can be used for fertilizer. Formaldehyde and ammonium salts are generally strictly prohibited, since they are unsafe for humans due to toxicity.

Chemical reagents thin the sludge, eliminate unpleasant odors and reduce the volume of domestic wastewater. They work even in an aggressive environment, if there is household chemical waste.

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, the second, the third. And suddenly, the pit begins to fill up and demand to be pumped out.And it has to be pumped out. Less often at first, then more and more often. What to do? How to return 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 has done its job, you need to pour the product into the pit Doctor Robik 509.
It is designed to eliminate long-standing problems with sewage: it liquefies thick masses, dissolves fossils. Also eliminates odor. And even cleans the pores in the ground, allowing liquid waste to easily seep into it. Gradually, the normal operation of the sewer or drainage system will be restored. After that, you can pour the composition Doctor Robik 109, which will already maintain a cesspool or sewer in an acceptable condition. For a cesspool with a volume of about 3 cubic meters, you will need 1 bottle Dr. Robik 509. And then after about a week, 1-2 sachets of 109, which will work 30-40 days.

In any sewer or septic tank, waste containing detergents is inevitably drained. As a result, soap deposits and growths accumulate on the pipes. They can be removed with Doctor Robik 809. Usually, products based on live bacteria cannot cope with soap and powders, and on the contrary, 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 tanks of cesspools from soap deposits. All Doctor Robik products can be used together without restrictions. Therefore, to completely clean the pit from silt and soapiness, you can Doctor Robik 509 and 809 pour at the same time. Dr. Robik's products are economical, effective and safe for human, animal and plant health.

Even the simplest type of sewerage with a cesspool can significantly increase the level of comfort in a suburban area. However, this solution has a significant disadvantage - the capacity for the accumulation and primary processing of wastewater requires periodic removal of the contents. Agree, the cleaning of cesspools should be carried out according to the rules so that the environment is not damaged.

For owners of private houses and cottages that are 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 the best option for getting rid of waste accumulations and learn how to implement it.

A detailed description of the methods used in practice is based on the personal experience of household owners. The requirements of the standards of public utilities are taken into account. The information is confirmed by photo and video applications.

There are three main ways for modern summer residents and homeowners to do this:

removal of sewage by pumping;
the use of preparations for the 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 it is often necessary to carry out cleaning activities in the complex. For example, after the use of biological preparations, additional pumping of sewage may be necessary.

When should you start cleaning up? The work strategy should be considered at the stage of creating a sewer, for example, by providing access roads for a sewage truck.

No need to wait until the drains fill the last cubic centimeter of the tank. Excessive filling of the cesspool several times increases the likelihood of contamination of the site. If two-thirds of the capacity is occupied by runoff, it's time to reduce their level using available funds.

Method # 1 - emptying and pumping out the cesspool

If desired, the cesspool can even be cleaned manually, using an ordinary bucket on a rope. The owners of small summer cottages do just that. The work is extremely unpleasant, it requires preparation. First you need to put on a protective suit or other clothing that you don’t mind getting dirty. This is necessary in order to protect the skin, drains can be quite aggressive.

For mechanical cleaning of cesspools, special machines are used - sludge pumps, which pump out the contents of the tank and take it out for disposal.

Then you need to take care of the protection of the respiratory tract, and it's not just the characteristic stench. Vapors coming 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 should pass out from the poisonous fumes, a partner can help him. In addition to a protective suit and a respirator, you need to wear high rubber boots or shoe covers, as well as gloves.

You will also need an airtight container in which the contents of the cesspool will be disposed of. Later, these sewage must be taken to a place intended for their discharge.

The distance between the vacuum truck and the cesspool should be no more than four meters. This point should be considered when choosing a place for sewerage, as well as with further redevelopment of the site.

Manual cleaning is a long, dangerous and unpleasant business. If the budget allows, it is better to use not a bucket, but a special one for pumping sewage into a container.

Things will go much faster, there will be much less dangerous contacts with a mass of effluents. 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. Periodically, such a pump must be flushed, as it is clogged with solid waste.

It is much more convenient to clean the cesspool with the help of specialized equipment, for example, a sludge pump. This is a machine that drives up to the site and pumps out waste through a special wide hose.

The distance between the sludge pump and the object to be cleaned should be no more than four meters. Pits more than three meters deep are not served by such equipment, but such deep structures are usually not found.

For the sake of safety, when manually cleaning the cesspool, it is better to perform all procedures together: one works at the bottom, and the second insures it from above

Even during the construction of the pit, one should take into account such a nuance: the sewers charge not for the volume of pumped out effluents, but for each exit. In order to reduce costs, it is necessary to calculate the volume of the cesspool in such a way that the amount of wastewater that is a multiple of the capacity of the sludge pump is intended for pumping. At the same time, it must be remembered that pumping starts if the pit is two-thirds full, and not “to the eyeballs”.

Method #2 - Biological Decomposition of Effluent

The microorganism-assisted effluent treatment process is widely used in various industrial septic tanks and VOCs. But even for cesspools, today a line of biological products has been developed that can do what is not possible when emptying cesspools - to reduce or completely eliminate the unpleasant smell characteristic of sewers.

Depending on the form of release of preparations for biological treatment, their preliminary preparation may be necessary. Usually the granules or powder just needs to be dissolved in a small amount of water.

The sewage truck leaves, and a suffocating sewer spirit hovers over the site for several more hours, or even days. The use of biological preparations significantly improves the situation.

To do this, you need to choose the appropriate tool and use it in accordance with the instructions. They are produced in the form of gels, liquids, powders, granules, etc.

Microorganisms decompose the contents of the sewage system into water and environmentally neutral sludge. From the permeable pit, water escapes into the surrounding soil, and silt gradually accumulates. Naturally, the degree of such purification is lower than that of high-tech VOCs, water cannot be used for irrigation, and sediment can not be used as fertilizer. But the filling rate of the cesspool is reduced significantly.

Of course, the sediment from the sewer facility itself will not go anywhere, it also needs to be removed or pumped out using the method described above with the involvement of sewers. There is another important nuance - not all wastewater can be processed with the help of bacteria.

Special preparations are intended for biological cleaning of cesspools. Some of them are designed to recycle toilet paper dissolved in drains.

Inorganic waste that enters the sewer accumulates at the bottom and reduces the amount of free space in the storage tank. Harsh household chemicals, such as those containing chlorine, can create an environment that is harmful to microorganisms. Owners of washing machines and dishwashers should be careful in this regard.

Method # 3 - the use of chemicals

If biological cleanup is a holiday for the environment, then the use of chemicals can be a threat.

To remove waste from cesspools, the most commonly used:

formaldehyde preparations;
nitrate oxidizing agents;
ammonium salts.

Even those who are far from chemistry know that formaldehyde is a dangerous substance. Its only advantage is its relatively 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 oxidants in terms of safety have much better characteristics. Their composition is close to the components of fertilizers of this type, i.e. with the correct dosage and following the instructions, such a cleaner is quite safe. These drugs are characterized by a high price, which is fully justified by high efficiency.

Ammonium salts are an effective chemical for cleaning pit pits, but such chemicals must be used with caution in accordance with the instructions.

When added to the sewer, the drug effectively dilutes the waste, while neutralizing unpleasant odors. After the effect of the drug is over, the recycled contents of the cesspool can be quickly pumped out and disposed of.

Another useful property of nitrate cleaners is that their effectiveness is not reduced by contact with even the most aggressive household chemicals. Means of this type are suitable for cleaning not only the pit, but the entire sewer system.

About how safe preparations based on ammonium salts, accurate data is currently not available. Therefore, when using this tool, like any aggressive chemistry, you need to carefully study the instructions and follow them exactly.

The presence of chlorine-containing products in wastewater can weaken the effect of the use of this drug, but according to reviews, it copes with unpleasant odors perfectly.

Waiting until the cesspool is filled to the top is a bad strategy. Cleaning should begin when the amount of sewage is 60-70% of the capacity

When choosing a sewer cleaning method, the specific situation should be taken into account. 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 problem with silting

Silting 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 soil due to the dense silty layer that covers the inner 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 tank.

One of the signs that silt is forming inside the cesspool is the appearance of a characteristic unpleasant odor - hydrogen sulfide vapor. When figuring out how to clean a silted cesspool, you need to remember that in this case you need not just neutralize the waste or pump out the contents.

If the cesspool fills up too quickly or silts up frequently, you may want to consider upgrading it with an additional container and an overflow.

All plaque should be removed from the walls and bottom of the container. To do this, chemical agents or chemical cleaning methods are used, but a combination of these methods is often the most effective. During mechanical cleaning, the bulk of the sewage is first pumped out. After that, using a hose, water must be supplied to the container under strong pressure.

The inner surface of the cesspool is treated with a jet in such a way as to break up the silt sediment and dismember it into separate small particles. Processing is carried out until the container is filled by about 25%. After that, the contents or silososom, and then disposed of.

For chemical cleaning of a silted structure, chemical cleaners are used to dissolve solid inclusions - the nitrate oxidizers already described above. They usually cope with silty deposits as well. After some time, all or almost all of the contents will become liquid, it can be pumped out without problems.

It is worth noting that the use of chemicals will cost significantly more than emptying by pumping, but this operation is easier to perform and takes less time. In the process of physical removal of sludge, you will have to put up with a lot of dirt, which usually accompanies this procedure.

In cesspools without a bottom, you will also have to clean or renew the sand and gravel filter, which is located below. The safest bet is to remove the entire contents of the filter and re-lay the clean components: a layer of sand, crushed stone and / or gravel about 40 centimeters thick.

To prevent silting of the cesspool, it is recommended to divert water from it to the filtration field. It is best to do it at the stage of creating a structure, but if you wish, 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 up, it should be immediately pumped out and the walls cleaned using a scraper or chemicals, such as nitrate oxidizers.

For the device of the filtration field, it is necessary 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 “pillow”. The pipe must be perforated, you just need to make holes in it at an equal distance.

Another layer of rubble is poured on top of the pipe, and then again covered with agrofiber. It turns out that the pipe is surrounded on all sides by filter materials. This will ensure the rapid removal of liquid contents from the cesspool and its safe disposal in the ground.

If problems with the cesspool began to occur more often, it makes sense to improve the operation of the structure in accessible ways. Some suit, which functions like a septic tank. To do this, next to the existing capacity, they arrange another one, approximately the same.

The first container must be airtight, and the second must be permeable or without a bottom. It is also possible to make the second container airtight, but then it is necessary to provide for the withdrawal of juices to the filtration field or to the drainage well. The overflow between these two departments is installed with a slight slope in the upper third of the containers.

First, the effluents will flow into the first compartment, where they will settle, solid waste will sink to the bottom, and the liquid component of the sewage content will overflow when it reaches the desired level.

The second compartment will receive mainly liquid effluents, which will move faster to the filtration field for further disposal. As a result, the pit will have to be cleaned much less frequently, and the likelihood of silting 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 warmed up in order to restore the sewerage.

In winter, drains in the cesspool can freeze, which will lead to problems in the sewerage system. To correct the situation, the frozen mass must be thawed. Traditionally, or is used for this. In the absence of power supply, fires are made near the frozen pit, a blowtorch is used, etc.

For craftsmen who have at least a little experience with electrics, another way to defrost a cesspool is available - heating directly with an electric current. In the middle of a frozen cesspool, a metal pin is driven in approximately to the freezing depth.

Then you need to take an electrical cable of a suitable length. Its end is cleaned and attached to the pin, and 220V power is supplied to the opposite end.

It may take quite a long 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 kind of work, it is mandatory to comply with electrical safety requirements, for example, use protective rubber gloves, shoes, etc.

If it is not the pit that freezes, but the sewer pipe leading to it, this indicates flaws in the laying of communications, for example, the trench was not deep enough or there was no insulation. You can fix these problems in the summer, and during cold weather, you should take care of defrosting the pipes.

Electric current can also be used for this. At the end of the cable, you need to strip a segment equal to the circumference of the pipe. To calculate this value, you just need to multiply the pipe diameter by 3.14, i.e. to the number "pi".

Then the protected wire is 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.

Although a cesspool is a very simple option for an autonomous sewage system, it requires proper maintenance and timely cleaning. Modern means allow you to get rid of waste accumulated in the construction quickly and efficiently.

Still have questions about cleaning cesspools? Or maybe you know other equally effective methods and have already tried them in practice? Ask your questions, share your experience in the block located at the bottom of the article.

A cesspool is a convenient autonomous installation that is used to collect waste from residents. In order for the system to work as long as possible, it must be properly maintained. In the absence of proper care, the cesspool will fail, and all waste will float to the surface. There are several ways to clean a cesspool, and most of them you can do yourself.

Indications for cleaning the cesspool

If an unpleasant smell hovers in the air, and midges fly over the installation, this indicates that it is time to clean the cesspool. If this is not done, then sludge will accumulate at the bottom of the sewer system, and this will lead to an early clogging. To avoid problems, it is recommended to clean at least once a year.

You can do the pumping of cesspools yourself, and for this it is not necessary to call a sewage machine. First you need to purchase a special container, the volume of which should be equal to the volume of the pit and a fecal pump.

Self-cleaning can be done if a small number of people use the sewer. In this case, the pit fills more slowly, and there will be no pumping problems. After the procedure, the cesspool should be rinsed to slow down the formation of stony deposits.

Self cleaning methods

There are three main ways to clean a cesspool, these are:

pumping method;
cleaning with biological preparations;
chemical cleaning.

Pumping out content

The very first and traditional method is pumping. You can carry out the process both independently and with the help of special services. The call of specialists will be needed if the pit has a decent size, since this service is not cheap.

If the installation is small, for example, in a summer cottage, then the owner himself can cope with the task of eliminating sewage. This will also require caution. When cleaning cesspools, appropriate protection should be worn:

rubberized clothing;
respirator;
durable shoes;
latex gloves.

Cleaning with a pump is not worth it alone, as methane is formed inside the cesspool. This gas is very dangerous for humans, so there should be a person nearby who can quickly come to the rescue in case of poisoning.

The use of biological preparations

Biological preparations are an excellent solution for cleaning a cesspool. The principle of operation of biological products is that under their action, feces and waste are converted into liquid. It has no smell and is safe for humans. Advantages of using biopreparations:

products break down fats, feces, toilet paper, and disinfect cesspools;
when cleaning, they do not have a negative impact on building materials (metal, brick, plastic);
preparations begin active work after 2 hours, and after 4 hours they eliminate an unpleasant odor.

Despite the advantages, this method has a drawback - the products cannot work at low temperatures, and their use in the winter is excluded. This is where chemicals come in.

Chemical method

To clean the cesspool chemically, use the following tools:

nitrate oxidizing agents;
ammonium compounds;
bleaching powder.

Such funds are not afraid of cold weather, but are extremely toxic. They cope well with various types of household waste and are resistant to aggressive environments. Chemicals have one significant disadvantage - they are unsafe for the environment.

For mechanical cleaning, a vacuum cleaner and an silo pump are used. To use such equipment, it is only necessary to provide it with an unhindered access to the cesspool.

A vacuum cleaner is a special machine that has a vacuum pump. With its help, the contents of the installation are removed. This method is considered the most convenient, since the pumping of cesspools is carried out quickly and efficiently. If desired, you can ask to flush the installation for an additional fee.

Like the previous methods, the vacuum cleaner has a drawback - it sucks up waste only in liquid form. To remove solid impurities, it is wise to use an ilosus, because it is able to turn them into a liquid and pump out impurities without difficulty. But he also has a minus: after using such a device, the pit will stop absorbing moisture, and you will have to call specialists more often.

In order for the cesspool to function as long and efficiently as possible, you can use a few simple tips:

If it was noticed that there is an unpleasant smell in the air, it is necessary to place special agents (liquid formulations or powders) in the cesspool that accelerate the decomposition process.
The state of the system must be constantly monitored and subjected to mechanical cleaning. If the sewer is full and it rains, then all unwanted waste will float out, and this is fraught with an unpleasant persistent smell.
To drain the soil faster, it is worth making a hole in the bottom of the pit and inserting a plastic pipe into it.
If the finished installation cannot cope with the incoming waste, it is advisable to dig another hole and connect them with a pipe.

When it was noticed that pumping out the cesspool began to be required more and more often, it would not be superfluous to restore the operation of the installation using available methods. Usually, problems begin in the winter, when drains begin to freeze, and the situation can only be corrected by defrosting them.

Usually, a heat gun or its homemade version is used for the procedure. The method requires a power supply, but in its absence, the use of fires, blowtorches, etc. is allowed.

There is another method, but it is only suitable for those people who have at least minimal experience in working with electricity. The essence of the method is that a long metal pin is driven in in the middle of the cesspool, a stripped electrical cable is connected to it, and a current of 220 V is supplied. When working, it is required to observe safety precautions and wear rubberized protective equipment. The whole procedure can take 24 hours, it all depends on the size of the sewer.

The question of how to get rid of silt in a cesspool is far from being idle, since the silting of a cesspool is a predictable and inevitable phenomenon. The owner will know that this process has begun by the unpleasant smell emanating from the pit and gradually spreading throughout the site. Silty deposits form on its walls, the outflow of liquid is difficult, which leads to slow cleaning of the sink and toilet bowl in the house. There are several options for solving the problem, but you should not postpone this issue indefinitely. By itself, the pit will not be cleared, and its condition will only worsen.

Sewer well without a bottom. It is an open hole dug on the site without any additional processing. It is the simplest and most inexpensive way to equip a cesspool, but not very effective, since the well quickly silts up and exudes an unpleasant odor.
A sealed structure, the bottom of which is poured with concrete, and the walls are lined with bricks or concreted.
A septic tank is the most efficient purification system, which has a complex design, capable of accumulating and processing waste. It is quite expensive, so it is not used so often.

Silt deposits sooner or later appear on any structure. There are several ways to remove sludge from a cesspool. The choice of one method or another depends on the type of sewer system.

Methods for cleaning the cesspool from silt deposits

Cleaning the sewage pit from silt is not a pleasant job. If you are not ready to do it yourself, it is better to use the services of a sewage company. But it must be taken into account that the length of the hose of the sewage machine is only three meters; for deeper pits, special equipment is used - a suction pump with a hose 16 meters long. Sludge is pumped out very quickly and without the participation of the owner of the site, who also does not have to worry about waste disposal. However, the services of professional plumbers are not cheap. There are several manual cleaning methods that can be handled without the involvement of specialists.

Sewerage cleaning with a sewer machine

Mechanical methods of sludge removal

An open cesspool can be cleaned in the old-fashioned way - with a bucket, rope and a shovel. Simply put, scoop liquid waste out of it with a bucket, and then collect all the sludge from the bottom of the well with a shovel. After that, you need to let the pit dry and fill the bottom with gravel to facilitate subsequent processing. This method is quite laborious and is suitable only for cesspools of shallow depth. In some cases, it is easier and more efficient to bury a well filled with feces and equip a new drain hole.

Another mechanical method is to dissolve the silt in water. To do this, first pump out 2/3 of the waste from the pit using a fecal pump. Then fill 1/3 of the hole with water, which must be supplied under high pressure. The flow of water will wash away the silt from the bottom. After that, the waste can be pumped out with a fecal pump.

Scheme of installing a pump in a sewer well

Note! For primary pumping, only a fecal pump with a grinder is suitable. If a water pump is used for secondary cleaning, then you need to stock up on additional nozzles. In order not to damage the equipment, they will have to be changed very often.

How to remove sludge with biological products

Biological preparations for cesspools are available in liquid and dry form.

Any type of cesspool structures can be cleaned using biological preparations, which consist of living microorganisms and enzymes. Bacteria in the course of their life activity absorb waste, eliminate unpleasant odors and produce organic and mineral substances, which can later be used as compost.

Preparations are produced industrially in the form of powders, tablets, cassettes or liquids. In dry products, bacteria are in a dormant state and are activated only when they enter a favorable environment. There are no special rules for choosing a specific tool, the only prerequisite for their use is strict adherence to the attached instructions. If the purified mass will be used as a fertilizer, experts recommend using biological products in the form of tablets. Powder products are best used in pits that have been pre-cleaned. In this case, the resulting liquid can even water the garden.

Biopreparations must be used in liquid form. It is necessary to dilute funds in strict accordance with the instructions.

Note! One liter of concentrated liquid preparation is able to clean waste with a volume of 2 cubic meters.

The bacteria used for cleaning do not destroy the materials used for the manufacture of cesspools, they are absolutely harmless to the environment and humans.

Microorganisms are sensitive to chlorine, alkalis and acids, therefore it is not recommended during their use to drain waste containing household chemicals, from the action of which they can die. In addition, bacteria cannot work at temperatures below +4 °C.

How to clean a hole with chemicals

Unlike biological, chemical preparations work effectively all year round. They can be used to clean septic tanks, open and sealed cesspools. Chemicals do an excellent job with unpleasant odors, decompose organic compounds, and reduce bottom sediment. However, they must be used very carefully, since they aggressively affect beneficial microorganisms and contribute to the reproduction of pathogenic bacteria. Chemicals can cause corrosion of metal elements of the sewer system.

Chemical preparation for cleaning drain pits

Note! Waste that has undergone chemical treatment cannot be used to fertilize the soil.

Chemicals are divided into three types:

Formaldehyde. In recent years, they have been used extremely rarely, as they contain carcinogens and are very toxic.

Means based on ammonium compounds. With their help, you can quickly eliminate unpleasant odors and speed up the process of decomposition of organic waste. However, their effectiveness is markedly reduced by contact with household chemicals.

nitrate oxidants. They contain surfactants, which help to quickly liquefy waste. Nitrate-based products can work in any aggressive environment and are considered the most effective and safe among all chemicals.

Despite their effectiveness, chemical and biological agents are not a panacea for the formation of silt deposits. Their use can only delay for some time the pumping of waste using sewage equipment.

How to get rid of worms in a cesspool

Worms start up in cesspools quite often, since any places of accumulation of sewage and waste serve as an excellent breeding ground for them. The process of development of the larvae is quite fast, so do not delay cleaning. There are several ways to get rid of worms in a cesspool.

Chlorination. Poison gas is highly toxic. But it acts only on the surface and cannot penetrate deeper layers. To achieve the result, the procedure will have to be repeated several times.

Boiling treatment. From exposure to high temperatures, the worms instantly die. This method also requires periodic repetition.

Treatment with chemicals. Any means of insect control in the form of tablets, granules or powder can be used, which must be dissolved in water according to the instructions and poured into a cesspool.

Cleaning the cesspool from silt is a problem that periodically arises in any private household. You need to understand that it will not resolve itself. Regardless of which method of the above you will use to achieve the effect, the activities will have to be carried out regularly.
