Why is the water not draining in the cesspool

Export of machinery

If the bottom is silted up and the pit fills up quickly, then there are services for pumping out silt masses in the private sector. It is believed that this is the most effective cleaning method. According to GOSTs, such cleaning should be carried out once every six months.Otherwise, the liquid will overflow the tank. The advantage of the method is the professional approach of the performer of the procedure.

The process takes 20-60 minutes. It all depends on the volume of the cavity and the degree of its contamination. Sometimes, the accumulation of silt masses can reach critical volumes. In this case, before the equipment starts pumping out, preliminary preparation is carried out. Various chemicals are used that corrode part of the accumulations.

Troubleshooting Methods

When choosing a method for eliminating problems with a cesspool, it is necessary to take into account the factor that provoked stagnation.

Silting with faecal matter

To remove silt, you will need a sewer-silo pump. With it, you first need to remove all the impurities, after which the bottom is cleaned under high pressure with the help of water. Additionally, with a lot of pollution, the crust is removed from the walls with the help of brushes. After cleaning all surfaces, you will need to re-wash the receiver using high pressure water.

If the crust is thick, in order to clean faster, you will need to add special bacteria to the water.

But it is important to remember that they are active only in a humid environment at a positive air temperature.

Removal of greasy film

Plaque can also be removed by flushing the system and using chemicals. The resulting fat is well corroded by bacteria, which turn it into compost and water. But since the drains often contain impurities of powders and other cleaning products, bacterial preparations cease to function. If no detergent components enter the drain, it is recommended to add bacteria such as “Vodogray” and “Microbec” to the receiver.Additionally, they turn toilet paper into compost, accelerate the decomposition of food products.

If bacteria are powerless, nitrate oxidizing agents, formaldehydes and ammonium compounds should be used. After contact with faecal sludge and fat, it quickly reacts and dissolves the crusts. Nitrate oxidizing agents are considered the safest for humans and nature. The mass formed after their use is allowed to be used as plant compost. If the choice is made in the direction of ammonium, they should be used only in the warm season, otherwise there will be no result. Formaldehydes are allowed to be used only in emergency cases, as they practically destroy all plants within a radius of 10 meters.

ground freezing

The elimination of this problem begins with the insulation of the pipeline. If it is not there, you should immediately warm up the pit itself. To do this, pour a few liters of boiling water into it. After that, with the help of a metal rod, it should be much higher in height than the tank itself, a small hole is made inside the drain right through all the merged masses. An electric wire is thrown onto the rod and connected to the network. It is better to put a metal pin closer to the soil, and not in the center of the drain. It may take 1-2 days for the receiver to warm up, taking into account its volume.

Insufficient receiver capacity

If for some reason the existing size of the tank is no longer enough, it will need to be increased. This is done quite simply. It is enough to dig another receiver nearby, which will be connected to the first one using a drain pipe. As soon as the level of the first cesspool is critical, all waste will go into the second compartment.

How to prevent the accumulation of water in the pit

To prevent dirt and grease from accumulating on the walls and bottom of the cesspool, some rules for operating the sewer system should be followed. Of course, it is impossible to completely prevent the accumulation of impurities that cause clogging and flooding of the pit, and after some time it will still have to be cleaned. However, to do this as little as possible, you need to:

• install a special mesh on the kitchen sink, which will prevent the penetration of solid waste into the sewer system;
• throw used toilet paper not into the toilet, but into a bucket;
• install an additional collector next to the cesspool.

Features of gas connections

When connecting gas stoves, columns and other types of equipment, flexible connections are also used. Unlike models for water, they are yellow and are not tested for environmental safety. For fixing, end steel or aluminum fittings are used. There are the following types of devices for connecting gas appliances:

• PVC hoses reinforced with polyester thread;
• synthetic rubber with stainless steel braid;
• bellows, made in the form of a corrugated stainless steel tube.

Causes of the disaster

Regardless of the type of sewerage facilities, rare cleaning and insufficient maintenance lead to the fact that the cesspool quickly fills up. What to do in such a situation is to establish the cause, and then the options for resolving the problem. The most common causes of clogging are:

The drain pit can overflow due to the large amount of drains

1. the pit can overflow due to the large volume of waste for which it is not designed, so the person making the cesspool must carefully analyze all the technical details before work;
2. rapid filling can occur through clogging with solid waste or natural "garbage": leaves, branches, earth;
3. this mostly applies to simple cesspools, in which effluents directly “contact” with the surrounding nature;
4. the lack of regular cleaning of solid debris is the reason why water does not leave the cesspool;
   the cesspool silted up due to the abundance of greasy waste.

It is the greasy particles of debris that create a dense layer of dirt. on the bottom and walls of sewage pitspreventing the outflow of water. A silted drain (bottom) causes why water does not leave the cesspool.

The listed situations can happen with every private sewage system, but not everyone knows how to make the water leave the cesspool.

How and what bacteria purify water

The use of chemicals to clean the local sewerage was actively used in ancient times.Such drugs can be used at any temperature (the main thing is that the contents of the septic tank do not freeze).

Cesspool bacteria are relatively inexpensive

They are not afraid:

• hard water;
• Impurities of chlorine;
• Other antiseptic substances.

But chemicals adversely affect both the sewer itself (especially those made of metal) and the atmosphere. Today, products based on active microscopic organisms are used for wastewater treatment.

The first group is anaerobic microorganisms, which are part of biological preparations for wastewater treatment. Their common feature is the ability to survive without oxygen. They are used as a tool for servicing sewers, septic tanks.

For microbacteria to work well, they need:

• Carbon;
• sulfates;
• Nitrates.

The second group is aerobic protozoa that require oxygen to live. Drains themselves do not contain air, so in order for bacteria to clean the water, an oxygen supply from a compressor is needed.

Preventive measures for clogging the cesspool

In order to prevent disruption of the cesspool and stagnation of water in it, it is enough to follow the recommendations to protect the drain from grease and silting.

It is required to pump out all sewage from the tank in a timely manner, while preventing it from

It is especially important to clean the drain before the onset of cold weather if you do not plan to use it in the winter.
Periodically flush the walls and bottom of the cesspool under high pressure.It is recommended to carry out such work at least once a year, but for the smooth functioning of the tank, it is better to do this every six months.
In the summer, special chemicals and bacteria should be poured directly into the drain, killing the unpleasant odor and removing the fatty film from the surface of the drain pit.
Before starting the construction of the receiver, it is required to correctly calculate its volume and depth.
It is impossible not to take into account the freezing point of the soil in a particular region.
If the winters are cold, consider insulating the drain.

If you follow all preventive measures and properly care for the cesspool, it will not cause any problems and will last as long as the owners need.

Other methods for solving the problem of an overflowing sump

The main task of the owner is to prevent spillage of wastewater over a large area of ​​​​the site. In addition to an unpleasant smell, waste products poison the soil, which can cause trouble not only in this area, but also among neighbors. And here we can't do without scandals.

mechanical cleaning

The method consists in the elimination of silty, fatty deposits on the internal surfaces of the sump. First, the pit is cleaned of drains, then they are lowered into a container, the layers are scraped off with a shovel, raised to the surface and disposed of.

Calling a vacuum truck

Pumping will remove not only water, but also waste. In the pumping process, wide pipes are used to create good pressure - they remove silt and fat layers. If the mass is compacted at the bottom, it is agitated with a steel hose tip or an ordinary bayonet shovel, stick. Then the waste is lifted with water and pumped out through the pump into the tank of the sewer.

The use of chemicals

Manufacturers offer a wide range cesspool cleaners yam:

Formalin (liquid formaldehyde). Inexpensive formulations of high toxicity. It is used as an antiseptic, accelerating the decomposition of waste.
Lime. Chlorine composition contains carcinogens and toxins

Apply with caution, cover the pit in the process of gas evolution, otherwise lime quickly loses active chlorine, which ensures the decomposition of organic matter.
nitrate oxidants. Safe compounds eliminate bad odors, make the contents of the pit homogeneous, but have a bad effect on iron.

Salt ammonium mixtures. By choosing formulations with 4-valent active nitrogen, the host receives a rapid dissolution of organic matter.

The compounds will remove odors, but use them carefully - ammonium is harmful to humans. Emptying is carried out only in a closed way.

Biologicals

The bacterial-enzymatic method of eliminating the problem of an overflowing sump is considered the simplest and most effective. Aerobic or anaerobic bacteria are used. The former work in the presence of oxygen, the latter cope with waste without access to fresh air. Microorganisms are safe for people, remove unpleasant odors, are neutral to any materials, and after processing the mass from the pit, they are used as fertilizer.

They produce biological preparations in powders, granules, liquids or tablets. Apply the compositions according to the instructions, monitor the temperature - bacteria require certain conditions for reproduction and interaction. It is impossible to pour chemicals, soapy water into a pit with living organisms, bacteria die from this.

Chemical cleaning

It is a universal way to get rid of sludge.Unlike mechanical, it is carried out exclusively independently, moreover, it completely eliminates the problem of stench. To get rid of sludge in this way, compounds of nitrates, ammonium, acids or formaldehyde are used (rarely, because it is highly toxic).

Ammonium for cesspool

Step by step instructions how to use chemicals clean out the pit:

1. The desired type of chemical compounds is selected. Experts recommend the use of nitrate cleaners - they are the safest for the environment and applicable to open structures;
2. The required amount is measured. The permissible concentration must not be exceeded - this can poison the soil or harm workers during subsequent waste treatment;
3. The connection 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 residues, grease) will take place there. On average, it takes from 3 to 6 hours to completely dissolve the waste (with a volume of up to 2 cubic meters);
4. Liquid effluents are pumped out using a drainage or fecal pump into a separate container or pit. If in the future it is planned to use another cleaning option, then the pit is washed with clean water.

This method is good for those who do not want to use the servants of the sewers. It is quite economical and easy to implement.

Advantages of dry cleaning of the pit from silt:

1. Chemicals can be used even in winter. Even though the top of the drain will be frozen, acids can still dissolve it. For example, biological preparations do not work in such conditions;
2. The unpleasant odor is immediately eliminated. In addition, it is neutralized for a long time even in the absence of chemical compounds;
3. This is a very cheap way to get rid of sludge. For example, Brilliance reagent 1 liter costs up to $ 7, 300 ml is required to clean 1 cube of feces of this liquid.

Flaws:

1. Cannot be used in plastic barrels and open septic tanks;
2. Has cumulative effects. The more cleanings - the longer the problem of silting is absent;
3. After chemical reagents, it is not advisable to use bioactivators for a long time. Chemistry neutralizes bacteria, so if you decide to switch to bacterial cleaning, you will need to rinse the pit well.

Cesspool: principle of operation, types

The cesspool is used as a storage tank for domestic waste. In the absence of a centralized communication system, this method of waste disposal is the only possible one for people living in private homes or in areas remote from the city.

Cesspool storage tanks are divided into 2 types:

1. Closed. Waste storage tank of a closed system, according to the type of shambo. Such a sewer sump is made completely sealed: a plastic or metal container is placed in the recess, reinforced concrete rings or the walls and bottom of the storage tank are tightly concreted. The deaf sump is environmentally safe, as it prevents soil penetration of wastewater.
2. Open. It means that the bottom and side surfaces of the sewage tank are not airtight and sewage seeps into the soil. Such tanks are contrary to sanitary standards, as they lead to environmental pollution. It is also forbidden to install them near hydraulic structures (wells, wells), as this is fraught with damage to the health of a person using water from these sources.

Despite the legislative ban, open-type cesspools are being equipped by many residents of rural areas (especially areas remote from the city).

Sludge and grease removal

One of the most common reasons for the frequent filling of the drain pit is the silting of its bottom. The drainage of the sewer is disturbed, as the silt deposits that have settled on the bottom interfere with the natural cleaning of the tank.

This happens if a lot of fat, detergents, toilet paper, and hard-to-decompose items get into the wastewater.

What to do if the pit silted up:

• Pump out the sewer from the liquid yourself, using a fecal pump or by calling a sewer;
• Fill the structure with ordinary water to soften the accumulation of silt at the bottom;
• A day after soaking, you need to add special preparations to the sewer for the decomposition of silt deposits (it is recommended to choose substances marked "Intensive", preparations such as "Mikrobek" and "Vodogray" are in good standing);
• After 2-3 days, thoroughly clean the tank again.

If a winter is on the street, then it will not be possible to remove the silty sediment with the help of biological products, since for their functioning in pit should be temperature over 10 degrees. In this case, it is recommended to use chemicals.

To clean the cesspools, special equipment or septic tanks are used.

It also happens that the sewer fills up quickly due to the high fat content in its drains. Such deposits settle on the bottom and walls of the sewer pipe, creating a dense sediment that prevents the liquid from leaving.

To clean the system of fat, you can also use biological products that are marked "Anti-grease", or use a special technique that will blow the sewer with hot water or steam under pressure.

The use of biological products

In addition to mechanical methods, bioactive preparations can be used to clean cesspools, which allow you to convert human waste into high-quality fertilizer. In addition, the use of biological products will lead to the minimization of unpleasant odors.

anaerobic bacteria

Anaerobic bacterial microorganisms can be used for post-treatment of sewage pits in the absence of a constant supply of oxygen. Anaerobic organisms obtain energy and carry out their functions by substrate phosphorylation. It is reasonable to use such bacteria in closed septic tanks or isolated sewer burials.

Aerobic bacteria

These microorganisms are able to most effectively purify wastewater and divide it into 2 layers. But aerobes continue their life cycle only with a constant supply of oxygen masses. Aerobic bacteria are useful for open pit latrines or for septic tanks with built-in oxygen supply.

Let's take a look at when is the best time to apply aerobic and anaerobic microorganisms to wastewater treatment. Experts say that it is advisable to use bacterial-based preparations in the summer, since living organisms cease to fulfill their life cycle at low temperatures. In addition, biological products are perfect for those people whose cesspool is located in a place inaccessible to sewage equipment.Another important nuance: bacteria process feces into good fertilizer, which will become an effective assistant to any summer resident and gardener.

Important! It is forbidden to throw construction debris, pieces of synthetic film and plastic into the sewer. Such substances do not decompose, and during mechanical cleaning they can clog the hose of the sewage equipment

Forms of release of biological products

There are 3 main types of biological products for wastewater treatment: tablet, powder and liquid. In each of the forms of such biological products there is a multimillion-strong army of bacteria and special enzymes that are designed to process human waste products.

Powdered biological products are found on store shelves in special bags, where bacterial microorganisms are in a state of hibernation. They can be brought into activity only when the powder is diluted with water (dilute according to the instructions specified by the manufacturer). Bacteria for such preparations are grown in the natural environment and are safe for humans (the latter fact has not been scientifically confirmed, therefore, one should be careful with such preparations and observe all safety and personal hygiene measures).

Gardeners and gardeners prefer to fertilize their plots with organic fertilizers - manure: horse, pig, sheep, rabbit, cow, as well as feces

Biological products in liquid form contain bacteria immediately in an active state. After the introduction of such an agent into the sewer, microorganisms begin to actively process feces into carbon and water. It should be noted that even a liter capacity of a biological product is enough to process 2 tons of sewage.

Preparations in tablet form are the most convenient to use. You just need to keep the proportions and throw the right amount of tablets into the drain, and the bacteria will do the rest. In addition to tablets, you can also find biologics in the form of cassettes or in soluble sachets on store shelves. But in no matter what kind you purchased a biological product, its composition and mechanism of action will be standard.

Did you know? The first sewers in history were built in the 6th century BC. e. in Ancient Rome.

It should be noted that cleaning cesspools with aerobic and anaerobic bacteria has its advantages and disadvantages. The advantages of this method:

1. Environmentally friendly method. Allows you to recycle waste into fertilizers that benefit the environment.
2. Preparations are sold in any plumbing store, so there will be no problems with the purchase.
3. Bacteria are able to remove unpleasant odors. In addition, they process waste silently, unlike a sewer machine.
4. The preparations are suitable for cesspools of all shapes, designs and sizes. It is only necessary to take into account the proportions when using.

Among the shortcomings should be noted:

1. In regions where temperatures are negative in winter, biological products are not used.
2. Not all drugs are equally effective for drains. Sometimes you need to try different types of biologics to achieve the desired effect.
3. The cost of a sachet of bacteria is relatively high.

How to restore the work of the drain pit?

Cleaning the pit in a technical way

Note! Plastic, films and other artificial materials cannot be decomposed.

anaerobic microbes facultative saprophytic bacteria
Important! When choosing microorganisms, consider the purpose for which they will be intended. There are funds for dry closets, cesspools, sewer systems.

In order for microorganisms to work as efficiently as possible, create the following conditions for them:

• In the waste pit, the liquid should cover the solid sediment by several centimeters. If necessary, pour several buckets of water into the container.
• Bacteria are active at a temperature of +4 + 30 degrees, so create the appropriate temperature conditions.
• Protect the pit from cleaning agents based on chlorine, manganese, and other antibacterial agents that kill bacteria.
• Use the drug in accordance with the instructions developed by the manufacturer. For example, some substances cannot be sprayed, they only need to be poured into one place.

Remember! If microbes are constantly living in the sewer, leave 30% sediment during cleaning so that they quickly restore their numbers.

Cleaning the waste pit with chemicals

Means	Advantages	Flaws
Formaldehydes	Can be used all year round	Very toxic, destroy the vegetation around the pit, the water after them must be taken out of the site
Nitrate oxidizers	The safety of the drug for the site	Quite expensive
Ammonium compounds	Dissolves all fatty deposits on the walls and recycles sludge	Work only during warm seasons

Note! Water purified by nitrate oxidizers can be used for irrigation.

Cleaning the sewage pit by defrosting sewage

For groundwater drainage from drain pits create a drainage system. Dig a trench with the bottom below the bottom of the tank. The width of the ditch is 15 cm. Pour crushed stone on the bottom, put a perforated pipe wrapped in geotextile on it. It should be tilted away from the pit and divert water into a ravine or temporary collection point. From above, pour large rubble again and cover it with earth. Drainage can be arranged without corrugated pipes. To do this, dig an inclined trench and fill it with sand, brushwood, and a large stone. To remove precipitation from above the structure, around the perimeter, also build a drainage ditch.

The cesspool is

As a rule, a cesspool is called exactly the tank that is simply dug in the ground, but neither walls nor a sealed bottom are built, and even more so, they do not install a septic tank in front of it. The scheme of operation of such a pit consists in the settling of heavy particles of garbage (feces, toilet paper, etc.) to the bottom, and the drainage of clarified water through the walls and bottom of the pit. It is noteworthy that at first drain hole for sewer drains are working properly. That is, water partially leaves it in the soil. The rest of the sludge must be pumped out or cleaned. As a rule, the frequency of pumping wastewater from the pit, depending on the intensity of use sewer system is once every two to three months. Sometimes more. But the problem arises when the water does not leave the drive and threatens to overflow into the sewer back. Why? It's not always clear.

What to do, if the cesspool fills up quickly and what are the reasons for the poor outflow of water, you can find out from the material below.

Reasons for the malfunction of the pit

If you notice that the drains have stopped leaving the drain pit through the bottom or its walls, and at the same time the tank fills up quickly, then the most common reason for this is that the cesspool has silted up. Faeces and any insoluble fat go into the drains and settle to the bottom of the tank. If there are a lot of such impurities, then over time, organic sludge turns into a thick crust that does not let water through. In addition, insoluble fat clogs the porous structure of the soil and prevents the outflow of water.

You can solve the problem by thoroughly cleaning the day and walls of the pit. Do it like this:

• Call a sewer machine and pump out all the water.
• The remaining sludge is washed away with a large pressure of warm water, while working with brushes along the bottom and walls of the pit. As a sludge softener, bacteria can be used, which not only neutralize the crust on the walls and bottom of the pit, but also reduce the volume of sludge.
• The softened organic matter is again pumped out by the equipment, re-washing the drain pit.

Why can't water go away

A cesspool is a reservoir that is dug directly into the ground. Usually a layer of rubble, sand or broken bricks is laid on the bottom, sometimes the bottom and walls are left unpaved. The principle of operation is the gradual seepage of effluents into the ground through the walls and bottom of the structure. Violation of the absorbent properties of the soil can occur for the following reasons:

1. Silting of the bottom - the appearance of a layer of fecal silt on the bottom, which prevents the passage of water into the soil.
2. Grease film on walls and bottom.
3. Soil freezing.
4. Insufficient receiver volume.Perhaps more people began to use the sewage system, additional devices appeared.
5. Low activity of bacteria that can not cope with the processing of organic matter. This happens for the following reasons: lack of organic substances in the system, too many household chemicals that kill the microflora.

General information about the cesspool

A cesspool is the best way to organize a sewerage system and wastewater outflow in a private house or in a country cottage. There are several options for organizing cesspools, for example, cesspool with overflow in a private house. The design of these devices is quite strong, they accumulate sewage, fecal matter and organic elements to a certain level, and then they are pumped out using special equipment - a sewer. But what to do if there is a high level of groundwater on the site, and in connection with this it is impossible to build a cesspool? How to remove groundwater from a cesspool if you have already encountered this problem?

Why is water so dangerous to sewer systems? Because groundwater, firstly, interferes with the installation of the pit itself, and also interferes with its effective functioning, as they enter the system

Therefore, it is extremely important to ensure maximum tightness already at the installation stage of the cesspool in order to avoid groundwater ingress. For this, sealed storage containers are used, complete tightness of the joints is ensured thanks to silicone and rubber seals.

Therefore, it is best to choose a sealed storage container where water will not enter. Suitable for you:

Where does the sewer flow Interesting facts

Inquisitive minds often ask questions that not every layman will come up with. For example, where does the sewer flow? And it's really, really interesting.

There are various rumors about this. Someone says that all city sewage flows directly into the river, so swimming on city beaches is not recommended.

Others argue that liquid waste goes underground through special drains, and there it is absorbed into the bowels of the soil.

note

However, if you only imagine how many millions of cubic meters the inhabitants of Moscow emit every day, then there will not be enough soil to “suck” it into yourself.

We have prepared for you interesting facts and photos about what happens to the sewer after it leaves our house.

Where does the sewer go?

It is unlikely that anyone wonders where the waste that we flush into sewer pipes goes. And they have a long journey ahead of them.

First of all, it must be said that enterprises use their own, individual cleaning system. That is, the waste of large factories is not connected with the city sewerage.

Everything is clear here. What about the city sewer? As an example of interesting facts about cities, we decided to take Moscow.

Often in our time, one can hear indignation about the fact that the Moscow River will soon turn into a swamp due to the fact that millions of tons of sewage household waste from the city and even enterprises flow into it almost directly.

In fact, everything is not so simple. If this were true, then the Moskva River would long ago become a real sump, and everyone who swims there would become infected with various sores.

It must be emphasized right away that the waste of human life in liquid form flows into special treatment facilities that are available in every city. This is the key point.

What happens to the sewer in the end

In a nutshell, it can be described as follows. When liquid waste from the city sewers flow into wastewater treatment plants, they go through the primary stage of purification, as a result of which sludge precipitates.

You will be surprised, but this is a really interesting fact: from this sludge they then make ... gas.

Schematically, the sewage treatment process is as follows:

So, at the very beginning, sewage enters the cleaning system through giant pipes. Traffic is approximately 2.5 million cubic meters per day:

Important

Next, the first stage of purification is filtration with special waste grates, which are larger than 10 mm:

Now the water enters the first settling tank, where it stays for exactly two hours. During this time, the settled organic matter is sent to the production of biogas, and the rest - further along the system:

This is the second sump:

In general, there is a constant analysis of water coming from city ​​effluents, piped and treated:

And only after such a thorough purification, the water enters the Moscow River directly from this reservoir:

Now you know where all the Moscow sewerage flows and what happens to sewage and other sewage. Approximately the same principle of cleaning work all the cities of the world.

Otherwise, the very existence of megacities would be impossible.
