How a cesspool with overflow is arranged: schemes and construction technology

Hermetically sealed device

There are many options for making a cesspool. It is convenient to meet the various needs of summer cottage owners. Use factory products so that the sewer pit will serve you for many years. The scheme of the cesspool of concrete rings involves the use of circles and base plates. Installation is fast. A cesspool in a private house can fully satisfy the needs of residents: concrete rings on the market are sold in a large assortment. You can easily pick up circles with the desired diameter.

During installation, the following order must be observed:

1. Dig a hole. An excavator is usually hired to perform earthworks;
2. Lay the main circle. Install subsequent rings. This work will be handled by experts. This requires the involvement of special equipment. An excavator is needed to set up the bottom, the rings will be lowered down by a crane. It is preferable to use solid products in construction;
3. The last circle should rise above the ground by 20 or 30 cm.

The device of a cesspool from concrete rings requires the involvement of experienced professionals and special equipment.

A cesspool with overflow is an excellent replacement for a central sewer in areas where it does not exist. The building has the following advantages:

• rare pumping with the help of sewage equipment;
• the ability to use water a second time to water green spaces;
• no bad odors;
• the ability to use water in large volumes;
• the absence of gurgling and other unpleasant sounds from the sewer system if the pit overflows.

If desired, the master will build a cesspool overflow structure on his own. To do this, you need to understand its device. 2 settling pits are connected to each other with a special pipe in the form of the letter "T".

The first container is connected to the house by a pipeline at an angle of 1.5 or 2 degrees towards the drain. Large particles sink to the bottom of the sump. Wastewater flows through a T-pipe into another container. This sump does not have a bottom. It is filled with geotextiles mixed with layers of sand, as well as rubble with broken bricks. Waste water passes through all layers. After purification, it goes into the ground without harming the environment. Loose or sandy soil makes it possible to fill the second hole with one rubble. Lay geotextile with a layer of black earth on top. Plant plants with a short root system.

The addition of special preparations containing bacteria to the first septic tank helps to improve the breakdown of organic waste. If oxygen enters the container, the biological product works better. Therefore, it is recommended to leave a hole in the lid of the septic tank.

The first sump is built from concrete rings, and the second from red brick. You will need sewer pipes made of plastic and a T-shaped pipe. Instead of the latter, you can take a corner. This is necessary to prevent the entry of sewage from the first container into the second.

If you have to dig a ditch by hand, then use this method. Install the first concrete ring in the place where the settling pit will be. Climb inside the product and dig in a circle. The weight of the ring will cause it to drop. When the concrete product is level with the ground, a second one is installed on it. Keep digging. Unnecessary earth is poured into a bucket, which is lifted by your assistant standing on top. After completing the installation of the rings, bring the pipes to the containers. A chisel and hammer will help you make holes in the concrete rings.

A plastic cesspool is a structure that the master creates without outside help. When installing, avoid pipe drops and sharp turns. When it is impossible to lay a straight pipeline, then make the angle of rotation obtuse. This design avoids blockages. Make sure that it is convenient for the sewer truck to drive up when the drains accumulate and you need to pump out the cesspool. The drawn diagram will help create a competent project for local sewage.

Do-it-yourself sewer pit from used car tires is a budget way to create comfortable living conditions. If the volume of wastewater is small, then this design is ideal: it is affordable and practical. Installation is not difficult. However, it is difficult to disassemble the construction of tires with your own hands. Homemade will last no more than 15 years.

It is difficult to shape a circle on your own from gas silicate blocks. Therefore, it is made in the form of a square or rectangle. Sealing is carried out using a special adhesive or cement mortar.

Installation of finished blocks

The easiest system to install and process wastewater is considered to be a ready-made complex, presented for sale in a collapsible form. Separate elements of factory septic tanks for a drain pit in a private house are made exactly to size, which allows them to be assembled as quickly as possible. The only weak point of these systems is the fact that they have a fixed volume set by the manufacturer. As a rule, the parameters of containers are designed for average consumption. To select the optimal system option, it is recommended to make approximate calculations of the load on the septic tank in advance.

The equipment of cesspools of this type usually does not cause any difficulties:

1. Dig a pit. The work is carried out according to the scheme standard for all pits. The bottom is equipped with a pillow made of a mixture of concrete and gravel.
2. After pouring the solution, a pause is made in the work until the concrete has completely hardened. From time to time it is sprinkled with water.
3. In the meantime, in a specialized store, you can choose a block for the accumulation and treatment of wastewater that is suitable in terms of volume. As a rule, its kit includes septic tanks, covers and rings.
4. The assembly of individual elements must be carried out in strict accordance with the instructions. It contains an installation diagram and recommendations for the arrangement of individual nodes.So, to increase the tightness of the butt sections of the underwater pipe and the main tank, it is recommended to use an acid-resistant sealant.
5. Before filling the finished structure with earth, it is recommended to test it. To do this, process water is allowed inside the system. During the procedure, it is necessary to check the correct laying angle of the sewer pipe and the tightness of the connections. If no leaks are found, the complex can be filled up.

Do-it-yourself cesspool of concrete rings - construction technology

In this lesson we will learn how to make a cesspool out of concrete do-it-yourself rings and take a closer look at the options for creating a cesspool in your home. It is worth noting that a pit of concrete rings can be made in various ways, the first is to fill the bottom with concrete mortar and thereby create an airtight structure, and the second way is to create a bottom from bulk materials, thereby making a septic tank system.

Cesspool of concrete rings

Hermetic cesspool of concrete rings

A cesspool made of concrete rings with the function of a sealed cesspool is an absolute plus for the soil and for the plants that grow nearby. But making a sealed cesspool, you directly depend on the arrival of a sewage machine, which once a month pumps out liquid from your cesspool. Of course, if your family consists of only a few people and in winter or summer you do not use a summer house or a country house, then it is quite important to build an airtight cesspool, because the fee for cleaning the cesspool is minimized and calls to them are made very rarely .

And of course, one of the main advantages of a sealed cesspool is the clean water of the well, which is located on your site.Because it is a leaky cesspool that is the main source of infection, which is carried in groundwater from a cesspool and can get into your well. Of course, seasoned builders will say if you build a cesspool 15-20 meters from the well, then your water is not afraid of pollution, but practice shows that this information is not always reliable, besides, there are also neighbors who also have cesspools , and the deposits and circulation of groundwater are a very difficult task to analyze.

To summarize, if you have a small family and you don’t get out into nature so often, then an airtight pit made of concrete rings is the choice you need.

Rules for arranging a cesspool

1. The cesspool should be located 15-20 meters from the well.
2. About 10 meters from the country house.
3. 4 meters from the fence.
4. The depth of the cesspool should be no more than 5 meters.

So, after the pit of the depth we need is ready, the moment comes for the installation of concrete rings. If you are not familiar with how to dig a hole, we advise you to look at this article. After the concrete rings are lowered, there comes a moment when it is necessary to hermetically insulate the base of the well and directly the joints between the rings, the isolation process can be done using concrete or resin mixtures, which you can either prepare yourself for this, you need to melt the asbestos (at the stake) in a bucket and fill the seams between the rings with it, but it will be extremely inconvenient to fill it without a special pump, so we still recommend using cement.

Next, it is necessary to cover the bottom surface of the pit with reinforced concrete slabs to ensure the safe access of this very machine for pumping out waste.

Cesspool pit with drainage system

A cesspool with a drainage system used to be very popular, partly due to the fact that the sewer was not in every house and simply the water resources that the family used during the year managed to go into the ground and simply simply disposed of naturally mixed with groundwater. But the consumption of water resources is growing, and with it, human needs are growing, which is why a cesspool with a drainage system simply simply cannot cope with a large amount of plums accumulated throughout the year, or even several months.

But it is worth noting that a cesspool can also be made with a drainage system by filling bulk materials at its bottom, and not pouring concrete. Then part of the water will go into the ground, and provided that the pit is filled, it will be possible to call a sewage truck. As a result, it will be cheaper to collect and pump out water, because less water will have to be pumped out.

As for the construction of this structure, the work essentially remains the same, the only thing that really changes is the pillow that we will make, at the bottom it consists of:

• Sand layer.
• A layer of rubble.
• And thermal bonded geotextiles.

The process of installing concrete rings in a cesspool

Construction of a cesspool made of bricks

A cesspool can be built with your own hands. Of course, this will require serious labor costs and some financial injections.

The construction of a cesspool begins with digging a pit.The top, most fertile layer of soil, it is better not to throw it away, but to evenly distribute it over the site. Sand and clay are removed. To fill the space at the manhole cover, about two cubic meters of soil should be left.

Brick is laid on a light foundation. The wall thickness of the cesspool is approximately half a brick. For better filtration between the bricks, it is necessary to leave gaps of five centimeters in size.

Ventilation is being built in the upper part of the pit. It is quite enough ventilation from an inch pipe, the end of which is better to bring out of the land plot.

At the bottom of the pit, a thin cushion of sand is made, which is then poured with concrete. It should be remembered that concrete hardens no earlier than after ten days. From above, the structure must be covered with a reinforced concrete structure. To do this, a brick pit is dug in from all sides twenty centimeters deep, a formwork is constructed from wood or corrugated board. Then, at a distance of one hundred millimeters from each other, reinforcement is laid.

The next step is to fill the floor. Concrete is poured to the desired thickness, then left to harden for one month. When the concrete has completely hardened, the formwork can be removed, the walls of the resulting structure can be laid out with bricks, plastered and smeared with bitumen. Such an overlap will not allow rainwater to enter the cesspool.

The overlap must be covered with a waterproofing layer, and then covered with a thick layer of soil.

For this type of cesspool, a double manhole cover should be used: this will prevent the fecal matter from freezing in winter and will not allow unpleasant odors to spread.

Different approaches to organizing a cesspool

The above brick cesspool scheme is considered one of the best, but there are other options. For example, the methods described in the article on building a drain pit with your own hands are the same technology.

Pit made of reinforced concrete rings

Building a pit from rings is perhaps the easiest. A concrete bottom is placed on a concrete reinforced pillow, then rings and a cover with a hole for the hatch are installed. The more rings, the larger the volume of the cesspool. It should be remembered that the standard height of the ring is ninety centimeters, the diameter is from seventy to two hundred centimeters.

The use of three rings is considered optimal. In this case, it should be borne in mind that the upper level of the septic tank should rise above the ground. It is better to make the junction of the drain pipe with the concrete structure soft (for example, use a fabric seal).

Cesspools are sometimes made of cast concrete. First, the bottom is poured, then - using reinforced formwork - the walls are made. For better waterproofing, the entire structure is treated with bitumen.

The use of polymer tanks could be called an ideal method for constructing cesspools, if not for their high cost. The method is distinguished by ease of installation and absolute tightness. The disadvantage of a polymer tank is the risk of crushing the container when the soil freezes. Before installing such a structure, it is necessary to carefully examine the soil.

Which option is easier to implement in the country

It is for this reason that a plastic septic tank with overflow for a private house is considered the best option for arranging an autonomous sewage system. For example, from the series "Maple". This is one capacity, which, depending on the model, is divided into 2 or 3 chambers. Thanks to this, installation can be performed with the arrangement of one pit, which somewhat reduces the amount of necessary earthwork.

Besides, thanks to the low weight of the container, you can install it even without the involvement of lifting equipment. And this will not only save money, but also ensure the safety of the landscape.

We note several other advantages of choosing Klen septic tanks:

• There are models with a capacity of up to 750 liters of treated wastewater per day.
• You can choose a model for high and low groundwater levels.
• There are complete sets with elongated necks to protect the system from frost.
• The strong case from sheet polypropylene surely maintains pressure of soil even at frost heaving.

Considering the cost, which is 2 times less than the price of biological treatment plants, the Klen septic tank can be considered one of the most profitable options for giving. And not only profitable, but also easy to install, as well as effective solutions for the treatment of domestic wastewater.
