The drain pit fills up quickly: what to do and how to solve the problem? Why water does not leave in the cesspool The drain pit is filled with groundwater, what to do.

If in a private house the sewer system is equipped with a cesspool, then it should be remembered that such a pit needs to be serviced periodically by calling a sewer machine.

Usually, with the correct calculation of the volume of the pit, it is enough to use such services once a year.

But many owners country houses notice that after several years of operation it fills up too quickly cesspool and need to be cleaned more often.

There are several signs that make it clear that the pit is filling up too quickly:

And if it is clear that the cesspool is filling up too quickly, what to do with this problem can be determined by identifying the cause of the accelerated filling.

There are several main reasons:

This is what a frozen stock looks like

Depending on the cause, you may be able to figure out what to do to keep the cesspool from filling up so quickly.

What to do when silting the bottom of the pit

First and most main reason why the cesspool quickly fills up is the silting of the bottom, especially if there is drainage below, through which part of the effluent in the form of water enters the ground.

Silting occurs in any case, but accelerates if fats enter the drain, detergents, large fractions of waste, toilet paper.

And if the cesspool is silted up, what to do is easy to understand.

Your actions should look like this:

So the principle of solving the problem is clear, if a cesspool has silted up, what to do with this problem is also clear.

After the cleaning procedure, the sewer will work properly for several years.

In the future, when you notice again that the drain pit has silted up, what to do, you will already know for sure.

It should be noted that if the silting of the bottom happened in winter, biological preparations in this case will be absolutely useless.

To solve the problem, use chemicals, which are nitrate oxidizing agents.

They quickly dilute the silty environment, reduce the volume of residual mass, eliminate bad smell from the cesspool.

But, chemicals will be ineffective if the drains in the pit are frozen.

Cesspool chemical preparation

If you continue to notice that the drain pit is quickly filling up, what to do in this case, we will consider further.

It is necessary to equip a new cesspool. At the same time, the old one does not need to be buried.

They should be connected with a pipe. Then you have a septic tank.

In the first pit, the effluents will be processed using natural processes and settled, decomposing into water and fractions.

Purified water will be able to flow into the next container, from which, after additional purification, it will seep into the soil through the drainage.

So the number of drains in the first pit will be significantly less, the sewer system will work more efficiently.

It looks like two cesspools connected by a pipe

Many in such cases decide to simply deepen the first drain hole. But still, the previously described method of solving the problem will be an order of magnitude more effective.

Moreover, it is quite simple to implement it.

What to do when the cesspool freezes

There may be problems with sewerage and in winter time. The main reason for their occurrence is the freezing of drains.

That is why in the cold season the water in the cesspool does not go away. How to proceed in such a case?

The problem is solved quite simply. Have to take copper wire, which is designed for 2 kW, prepare a metal pin, about 20 cm long, as well as a small hook.

So the cesspool is defrosted in winter. But this method should only be used if you are experienced with electricity.

At the same time, it is necessary to work in rubber boots. If there are no skills, such actions can be dangerous, then they should be entrusted to a specialist.

Protective special clothing (gloves and rubber boots)

If it's just frozen drain pipe, it should be wrapped once with bare copper wire. Determining the length of the conductor is quite simple.

You need to multiply the diameter of the pipe by 3.14. Subsequently, the wire is connected to the mains, leaving it like that for a couple of hours.

After this time, the network is de-energized, the wire is removed from the pipe. When carrying out such work, it is necessary to exclude the presence of children and animals in the immediate vicinity.

Cesspool Care Like Any Other technical system, is a necessary and unavoidable measure. The usual type of such maintenance is regular sewage, about once every twelve months, most often in the fall. However, this is true provided that the pit works with the same quality. Unfortunately, it suffers from the disadvantage that as it is used, the intensity of its action decreases, and it becomes necessary to service it more often. The deterioration of work occurs gradually, and at first it is even imperceptible, but sooner or later the need Maintenance becomes obvious. How to solve this problem, as well as eliminate other common problems, is described in the article.

The fight against dysfunction of the cesspool

Signs of bad performance

The main signs of a decrease in the efficiency of a septic tank are:

bottom silting;
contamination of the walls of the pit with hard-to-wash fractions (fat deposits), which is especially important for;
the appearance of an extremely unpleasant odor;
the pit fills up quickly.

Bottom silting

If the cesspool is silted up, then urgent measures must be taken:

Call a sewer truck.
Fill sewage with water in order to liquefy the silt deposits as much as possible.
Use biopreparations with a high concentration of bacteria.

Dirty walls and odor

One of the means by which cesspools are effectively maintained is biological preparations. They include microorganisms, for which the substances that clog the cesspool are food. It may sound a bit unappetizing, but you can't deny their usefulness.

The main result of the vital activity of these microbes is the cleaning of all elements of the sewer system. At the same time, an unpleasant odor is eliminated, the patency of pipes improves, and all organic components of waste products become chemically passive, and therefore harmless to the health of people and animals.

The result of the action of biological products is:

Lowering the level of sewage in the cesspool;
A kind of "cleaning cesspools", eliminating odors;
Liquefaction of solid waste;
cleaning internal surfaces pipes and septic tanks from fats;
Restoring the performance of drainage systems;
Prevention of siltation of the bottom of cesspools.

Despite the similarity of the mechanism of action, biologics differ in the direction of their application.

Here are some examples of their specialization:

The drug "Microbec" - is intended for biological neutralization of the contents of sewage collectors. It cleans underground utilities, eliminates odor and reduces the frequency of necessary sewage.
The drug "Vodogray" - decomposes large inclusions of sewage. With its regular use, such components that are dangerous for the good functioning of the sewage system, such as cleanings and peels, paper, and fats, rot much faster. It is irreplaceable for use in street dry closets. The unpleasant smell disappears in two weeks, and in three months any sewage turns into a harmless compost suitable for use as fertilizer. It happens that the drain pit overflows - water does not go away. When using "Vodograya", work is restored drainage system if it was clogged, and the bottom and walls are completely cleaned.

Rapid filling of the drain hole

If the cesspool is filled too quickly, some owners of dachas and country houses express their intention to fill it up and dig a new one. Such a measure will not give the desired effect, it is much better to dig another one and connect it to the first overflow pipe. The capacity will double and the degree of purification will increase. It should only be remembered about sanitary measures to prevent contamination of wells with drinking water, to them from any of the pits should not be less than thirty meters according to.

Actions in case of freezing of the sewer system

The main reason that the cesspool and sewer pipes are frozen is, as a rule, its insufficient thermal insulation and other mistakes made during construction. However, in our latitudes there are such frosts that even an impeccably executed septic tank freezes through. This is especially true in relation to, because it is rarely used.

There is a way to defrost a cesspool, it is based on the principle of resistive heating of a conductor. For those who have never had experience with electrical diagrams and unfamiliar with at least the basics of electrical engineering, it is better not to use it.

Necessary materials:

copper wire "2 squares" (2 kW.);
a metal pin about 15-20 centimeters long;
small hook.

A voltage tester would also be useful in order to use a regular household outlet and an extension cord if it is not possible to connect to the input power terminals.

Pro tip:

Particular attention should be paid to electrical safety issues. You need to work only in rubber shoes and special gloves for electricians. Children should not be around.

There are two heating options:

If the cesspool did not freeze in winter, and it's just a pipe, everything is solved simply. Frozen ground is a conductor, but its resistance is high enough, so the ground is a natural current limiter. In this case, it is necessary to strip the wire to a length slightly exceeding the value calculated by the formula L = 3.14 x D. For example, if a sewer pipe with a diameter of 110 mm is used, then the length of the stripped section of the copper wire will be 35 cm. Then this section wraps around the pipe, and the other end is inserted into the phase connector of the socket. In a couple of hours of current passing, the pipe will warm up, and the movement in it will be restored.
If the pit is frozen through, then an iron pin should be driven into its middle. The stripped end of the wire is attached to the pin, and a voltage of 220 V is applied to its other end. To do this, you can use a hook attached to the wire, it can be carefully thrown onto the current-carrying element. You can also simply insert the wire into the phase connector of the socket, without a hook, if it reaches. It will take a lot of time, from half a day to a full 24 hours, but the result will be.

Pro tip:

It is even harder to drive a pin into a frozen pit than to drive it into ice, so it is still better to heat the surface of frozen sewage with a blowtorch.

In both cases, at the end of the defrosting, the current is first turned off, and only then the wires are removed.

More simple ways, associated with the heating of frozen volumes with fan heaters - "dukes", blowtorches or bonfires set up near fires, do not require special training and explanations.

At the very beginning, when you just built new house, drained, no problems arise. But the house can be called a living organism - it requires constant attention. After a couple of years, you may notice that septic tank fills up fast. If you pumped out its contents once a year, now you have to call a sewage truck almost every month. What is the reason and how to fix this situation?

Reasons for the rapid filling of the septic tank

Right from the start, once you've done the sewer, she needs permanent care. Only in this case it will function normally for a long time. This does not mean that you need to check its condition every day - just pump out wastewater in a timely manner. New the septic tank is filling up in about a year with an average intensity of sewer use. Gradually, the intervals between pumpings will become smaller and smaller, which means that it is time to tackle this problem. What most often leads to the fact that water stops leaving the pit?

On the walls sewer pipes fat is gradually deposited, and the soil is impregnated with it. As a result, the soil stops absorbing water.
Over time, silt may form at the bottom of the pit, which also prevents the water from leaving.
Or you just use the sewer very heavily.

All this leads to cesspit fills up quickly and even a tightly closed manhole cover does not save from an unpleasant smell. In some situations, the pumping frequency can be up to twice a month.

How to solve this problem?

There are two main solutions - the use of biological products and the arrangement of a second pit. Let's look at both methods in more detail.

The use of preparations for dry closets

The most common cause rapid overflow of the pit - accumulation of silt at its bottom. They do not allow the liquid to normally go into the soil. Try to do the following.

During cleaning, try not to use the pit - let the bacteria work - with large quantity they may not be able to handle the content. You may need to repeat this process a few more times. What effect can you notice after using biological preparations?

The volume of the contents of the pit will noticeably decrease.
Solid deposits liquefy.
The walls of the pit, sewer pipes will be cleaned of a layer of greasy plaque.
The unpleasant smell will first decrease, and then disappear completely.
The pit will stop filling up so quickly.

Microorganisms that are part of these drugs are completely safe for humans. There are many similar drugs, they are all slightly different, so be sure to read the instructions before use - how much to use, how long it is not recommended to use the pit. As you can see, the problem of a silty bottom and greasy sewer pipes is solved very simply.

Second collector device

If a septic tank fills up fast then try making a second hole. This does not mean that the old one needs to be buried and no longer used. A second hole is dug next to the first hole. Between themselves, they are connected by a pipe installed at a slight slope. Water will flow through it. What will it give you?

Well, the most important thing is that the work of the sewerage system will not only get better, but will be even more efficient. Waste water will be better cleaned, faster to leave. The principle of operation is - solid waste settle in the old pit, and water enters the first pit through a pipe.

If you think that now you will have to pump out both pits, then don’t worry - you only need to pump out the old one, and the water will leave itself from the new one. For greater efficiency, pour biological preparations into the first pit from time to time to clean it. It is better to do this prophylactically, so as not to encounter the problem of rapid filling again in the future.

Why does the cesspool overflow in winter?

Quite often it happens that in summer there are no problems with the pit, and in winter it suddenly turns out that the septic tank is not just overcrowded, but to such an extent that all sewage begins to overflow. How is this possible and why?

The thing is, most likely, that the contents of the pit began to freeze. This usually happens if the work on the septic tank was carried out incorrectly, but there are exceptions. What to do in such cases? If you have an idea about electrical engineering, know the safety rules when working with it, then try using the following method.

If the pit is partially frozen, take a 2 kW copper wire, a small hook and a metal pin about 20 cm long.

Strip the end of the wire and connect to the pin.
Place the pin in the center of the frozen drains.

A hook is fixed on the second end of the wire, which is thrown over the element connected to the current. The second option - you can use a wire with a plug to connect to an outlet.

In order for the pit to completely defrost, you will have to wait at least a day. After that, the wire must be de-energized and only then pull out the pin. If you have never dealt with such things, then it is better to turn to people who have more extensive practical experience in the field of electrical appliances.

As you can see, any problems are solved and quite easily. If the water has stopped leaving the septic tank, try to start using biological preparations, and at the same time think about the possibility of digging a second collector for the future.

For a comfortable stay in a private house, whether in the city or in the country, it is necessary that the sewerage system works constantly and with the required performance. Business interruptions will negatively affect your stay, but unfortunately they do happen. There are many reasons why this happens. And if the cesspool fills up quickly in your area, what to do in this case? Consider the main causes and methods of solving this? question.

For the proper functioning of your sewer system, it is necessary to ensure that it is properly maintained. The main one is the timely pumping out of wastewater that has accumulated in a septic tank or pit, as a rule, this is an accumulation of heavy suspensions or sludge left after waste processing.

Depending on the volume of the septic tank and the average daily output of wastewater, cleaning is done once a year, but this can happen more often if the pit begins to fill up quickly. If this happens, then it is likely that additional measures need to be taken to improve the performance of the cesspool or septic tank.

The main reasons due to which a deterioration in the performance of a septic tank may occur can be:

Too high sump filling rate.
The bottom has silted up.
Due to the layers of fat on the walls of sewer pipes and the walls of the septic tank, as a result of which the coefficient of absorption of liquids has decreased in the soil.

As a result of these reasons, the sewer pit may collect too much wastewater, and as a result, the sewer truck will have to be called more often, and an unpleasant odor may appear, even with the hatch closed.

In order to prevent flooding of the house when the septic tank is overflowing, as well as in the case on the site, it is recommended to install .’

Another indicator of the incorrect operation of the septic tank is, when it appears, you should pay attention to the operation of your local sewage system.

Bottom silting

Cleaning a silted septic tank

Very often, the cesspool fills up quickly due to the silted bottom, what to do in this case and how to get rid of the problem? First you need to pump out all the accumulated waste in the pit using a sewage machine.

The remains of wastewater not pumped out by the machine (there should not be many of them) are filled with water so that they soften as much as possible and turn into liquid state.

After some time, special biological bacteria for the septic tank must be added to the pit, which will help get rid of the remaining sludge.

When organizing a cesspool or septic tank, it is worth remembering the requirements sanitary norms- it is necessary to place the septic tank no closer than 30 meters to the water source (well) in order to prevent its contamination.

Freezing drains

If in winter the cesspool fills up quickly, then, as a rule, this is a consequence of its freezing. What to do in this case?

Usually icing of a septic tank occurs if local treatment plant was incorrectly insulated or poor quality was produced installation work.

But even if all the installation work and thermal insulation were done correctly, the pit can still freeze or freeze. As a result, septic processes will slow down, bacteria may die, and the performance of the treatment plant may drop significantly.

Such a problem may arise, including due to the intermittent use of plumbing fixtures in the winter.

To defrost the contents of the pit, you can use a very effective way– resistive heating of conductors. To do this, take a copper wire that can pass 2 kW, a small hook and a metal pin about 20 cm long.

Please note that in order to carry out this method of defrosting, you need to understand a little bit in electrics and strictly follow the rules and safety measures when handling electric shock.

When the entire pit freezes, the following defrosting method is applied:

A metal pin is driven into the center of the frozen sewage.
One end of the copper wire is stripped and connected to the pin.
The other end of the wire must be connected to the element connected to electrical network using a hook. You can also use a wire that is powered from the socket phase.
It will take about one or even two days to completely thaw frozen drains.
After defrosting occurs, you must first de-energize the wire, and only then pull it out of the pit, but not in the reverse order, as this can harm your health as a result of an electric shock.

Draw your attention to! When staying near the pit during the defrosting process described above, it is imperative to wear protective gloves and rubberized shoes, in accordance with safety requirements. Take care of your health, do not neglect the prescribed laws.

How to unfreeze a pipe hot water

Freezing only metal pipe, the sewerage system should be heated in a different way:

The copper wire is stripped in such a way that the stripped part can wrap the icy pipe once.
The other end of the wire, as in the first case, is connected to the power supply.
The duration of the defrosting procedure will be much faster, approximately several hours.

One more, more safe way thaw a frozen pipe - serve inside hot water using a special device, as shown in the figure.

To unfreeze plastic pipe it is necessary to use special equipment - devices that are capable of supplying a large current to the pipe, about 400 A, under its influence the ice melts quickly enough.

As a rule, specialists who service septic tanks have such equipment. For home use can apply welding machine, whose contacts should be in water (in ice) and located on opposite sides of the frozen pipe.

Local sewer networks for private houses include either cesspools or septic tanks. The most simple design- This is a cesspool in which sewage is simply collected. Partially, water penetrates into the layers of soil, but the bulk and sewage must be pumped out. The frequency of pumping depends on the volume of the well and on the ability of water to pass through the soil. But, as often happens, even such a simple tank starts to work poorly. Therefore, you can often hear the question, the cesspool is quickly filling up - what to do?

Reasons for the rapid filling of the cesspool

There are many reasons why the water in the cesspool does not go away. One of the main ones is the volume of the reservoir, which does not correspond to the amount of sewage. That is, at the very beginning, the developer planned that drains from the bathroom and toilet would merge into the cesspool. But over time, they were joined by a bath, summer kitchen, washing machines and dishwashers. To solve this problem, you just need to increase the number of pumpdowns.

The second reason is the level of groundwater. Unfortunately, this indicator is neglected by many developers. Many do not consider it necessary to find out at what depth these waters lie. But it is they, as practice shows, that are the cause of the overflow. sewer wells. Especially during rainy and snowmelt periods. After all, sewage is often built in the summer, and at this time the level of groundwater is the lowest. Therefore, when digging a hole, the foreman does not encounter a water layer.

If the pit often overflows, it is necessary to increase the number of pumping

It started to rain in autumn, and the pit began to fill up more intensively. Water pours through the lid and hatch, sewage spreads over the territory of the site, an unpleasant smell appears. This problem can be solved in the same way as in the first case - to increase the frequency of pumping out wastewater.

Types of cesspools

This is another reason why the water in the cesspool does not go away. It is identical to the first reason, but there are differences. There are two types of sewer wells: hermetic and non-hermetic. In the first case, this is a reservoir, the volume of which must be accurately determined. There is a formula by which the volume is determined. It is based on:

the number of people using the sewer system;
the amount of water consumed by one person;
the frequency of pumping out the cesspool.

For example, three people live in a house, it is planned to pump out once a month, that is, every 30 days. A person consumes 200 liters of water (0.2 m³) per day. The volume of the pit will be equal to: 3 × 30x0.2 = 18 m³. If you increase the number of pumpings, you can reduce the volume of the tank. True, the services of a sewage truck are not cheap. You can also pump out sewage with your own hands, using a fecal pump, on extreme case rope bucket.

Self-pumping the contents of the pit

Attention! Pumped waste must be disposed of in certain places specially allocated for this.

As for leaky cesspools, the number of pumpings in it is less due to the fact that part of the water seeps into the ground. But even such constructions are subject to overflow. The main reason for this is oil and fat deposits, small polymer materials and films, hair, wool from animals. All this does not rot and settles to the bottom and walls of cesspools, making them airtight.

Solution of the siltation process

So, if a cesspool silted up - what to do? There are several options for solving this problem.

Pit filled with water

First of all, you need to pump out sewage. Empty the pit to the end, while trying to pump out the silt that has settled to the bottom. Often it becomes very dense, and even a sewage truck cannot pump it out. Therefore, before pumping it is necessary to gut the silt with any long object. It can be a pipe, a board, a rail, and so on. The sludge becomes soft, part of it rises into the water, so some volume will be pumped by the pump.

There is another way to approach this problem. Pump out first dirty water from the pit, and then pump a clean one under pressure, washing away fat and oil deposits from the walls. A very effective measure. After that, pumping is performed, and again filled pure water, with the help of which the silt deposits located at the bottom of the pit are liquefied. After a couple of hours, the hole must be emptied again.

There is another option, in which it is not necessary to pump out sewage. To do this, you can use chemicals for cesspools. But before cleaning a cesspool without pumping out, it is necessary to choose the right chemical cleaner.

Doctor Robik 609

There are three types.

liquid formaldehyde solution. A highly toxic drug that is now banned for use. Although it is very effective and inexpensive.
Nitrate type oxidizers. With their help, any waste is liquefied, in addition, this drug is environmentally friendly, but it has the highest price of all the chemicals offered for cesspools. By the way, oxidizing agents do not react to aggressive environments, they are in any sewage destroy all organic and inorganic impurities.
ammonium compounds. Same effective drug, but practically loses its qualities in aggressive environments (with a large amount of chlorine, detergents).

If the water in the cesspool does not go away, then you just need to pour the selected and purchased chemical preparation inside. It will begin to liquefy the silt deposits, turning them into fine suspensions. That is, it will happen chemical reaction, one of the residual components of which will be carbon dioxide. Therefore, pouring the chemical into the well, care must be taken that the gas can freely leave it. For example, you just need to leave the hatch open.

Through certain time the contents of the cesspool must be pumped out together with the liquefied sludge. After that, the walls of the tank are washed clean water under pressure. And the pit is again ready to receive drains from the sewerage system and not overflow.

Answering the question of how to clean a cesspool without pumping out, one more option can be offered. To do this, you will have to use biopreparations. They simply fall asleep inside the well, where putrefactive bacteria come to life and begin to process organic matter. If a sealed tank was installed for a private house, then anaerobic bacteria should be poured into it, which feel good without oxygen. If the capacity for the cesspool is leaky, then aerobic bacteria are filled up, which die without oxygen.

Biological product for a cesspool or septic tank

Attention! When arranging a cesspool for a private house, it is necessary to immediately launch putrefactive bacteria at the beginning of its operation. Thus, all the problems associated with its silting will be solved immediately.

Frozen cesspool

If the water in the cesspool does not go away in winter, and it overflows, then this is a guarantee that everything inside is frozen. What to do in this case? Of course, the first step is to melt the ice. If it is not very thick, then you just need to pour hot water into the pit.

Frozen cesspool

But if it is thick, then hot water will not solve this problem. Therefore, you have to think various ways defrost. For example, use a blowtorch or gas burner. You can install a heat fan on the manhole cover so that it directs the flow of warm air into the well. In a few hours of work, the drains will thaw - that's for sure. The time will depend on the thickness of the ice. Someone offers different homemade appliances operating on electricity. Dangerous things, and if you are not an electrical specialist, then it is better not to use them. And the effectiveness of their work is highly questionable.

The best solution so that the cesspool does not freeze is to insulate it. Fortunately, today manufacturers offer a large number of various heat-insulating inexpensive materials and technologies.

Cleaning cesspools and toilets is a basic requirement for their smooth and trouble-free operation. If you approach this issue competently, then the sewerage of a private house will work efficiently without creating problems.
