Plastic containers for sewerage. Sewage tank for a private house - which type to choose, advantages and installation Sewage tanks for a private house

Installation of a sewerage system is a mandatory stage in the construction of any private home. If your site is located within the administrative boundaries of the city, then the solution to this issue comes down to connecting the home sewer network to the city drainage collector.

For those residents whose houses are located outside of large settlements, the problem of collection and disposal Wastewater you have to decide for yourself. When designing and constructing autonomous treatment facilities, it is important to correctly select the volume and type of tank for the sewerage system, since these parameters will determine throughput, reliability and durability of the entire cleaning system.

Types of autonomous treatment facilities

Currently, several types of autonomous treatment facilities are used in private residential buildings for the disposal of liquid household waste.

When choosing a suitable option, I advise you to proceed from the size of the family budget for construction, the total average daily volume of clean drinking water, and requirements for the degree of wastewater treatment.

1. An ordinary cesspool is considered the simplest and most primitive device, since it is an ordinary large tank, intended exclusively for the accumulation and storage of sewage and liquid waste. The only advantage cesspool, is the low manufacturing price. At the same time, it must be borne in mind that in the future its operation will cost much more, since it will constantly require additional expenses for periodic pumping and removal of sewage;

1. Double chamber or three-chamber septic tank is a completely autonomous device that is capable of fully performing full cycle cleaning household waste in a continuous mode. All sewer tanks in a multi-chamber septic tank are connected to each other in series using plastic ones, and each individual flow-storage chamber serves as a sump. This method allows you to obtain clarified clean water, without unpleasant odor and mechanical impurities;

1. The deep biological treatment system also consists of several chambers connected in series, one of which is an aeration tank. At the bottom of the aeration tank there are nozzles through which air is constantly blown, thereby saturating the contaminated water with oxygen. In conditions of excess oxygen, aerobic biologically active bacteria develop in water, which quickly decompose fats, proteins and other organic matter, into the elementary constituent particles.
   As a result of the active activity of aerobic bacteria, the output of such a device is purified water, which can be used for technical purposes, and a small amount of bottom sludge, which can be added to the soil as an organic fertilizer;

A biological wastewater treatment plant cannot be called a completely autonomous treatment facility, since its operation requires a constant connection to electricity. Such devices are quite expensive, but thanks to the built-in pump, they can be used in forced sewer systems.

How to calculate tank volume

In order to correctly calculate the optimal volume of a septic tank or storage tank for sewage, you need to understand what is the maximum volume of clean water that will be consumed by all residents in the house in one day. For residential buildings permanent residence, the generally accepted average daily water consumption is determined at the rate of 150 liters per day per person.

For each of the presented types of autonomous treatment facilities there is its own separate calculation method, so below we will present brief instructions that describe in detail how to determine the required volume of tanks in each specific case.

1. With factory-made biological treatment plants, this issue is most easily resolved, since each model of such devices is initially designed for a certain number of residents. Thus, to choose the right model for yourself, you just need to indicate to the seller or official dealer, which maximum amount people can live in your house at the same time;

1. When choosing the volume of a storage tank, I advise you to proceed from such a calculation that pumping and removal of wastewater should be performed no more than once or twice a month. For example, if four people permanently live in a house, then with an average daily water consumption of 150 l/person, the volume storage tank must be no less than: 150 l/person. * 4 people * 15 days = 9000 liters, or in other words 9 m³;
2. In normal operation of a two-chamber or three-chamber septic tank, it will take at least three days to clarify and purify the entire volume of contaminated wastewater. Thus, the total volume of all settling chambers for a septic tank must simultaneously contain the amount of water that is consumed by all residents of the house for three days. For example, for a private house in which five people permanently live, the volume of the septic tank is calculated using the following formula: 150 l/person. * 5 people * 3 days = 2250 liters, or 2.25 m³.

It may happen that during the arrival of guests, or in the event of a simultaneous volley discharge of a large amount of wastewater, the calculated volume of storage tanks may not be enough. To avoid unforeseen situations, when designing and installing tanks for autonomous sewerage, I advise increasing the resulting calculated value by 30%.

Option 1: metal containers

In earlier times, all parts and assemblies for sewerage systems were made primarily of metal. This material has its advantages and disadvantages, however in this case, the disadvantages turned out to be more significant, therefore, in modern sewer systems, metal containers are practically never used anywhere.

In the same time, metal barrels of a suitable volume can be purchased inexpensively at scrap metal collection points or at dismantling old industrial enterprises, therefore, some craftsmen use used metal containers as sewer storage tanks or settling tanks.

1. The metal has sufficient rigidity and high strength, therefore, products made from it are not destroyed or deformed under the influence of significant pressure from a thick layer of soil;

1. Metaltanksabsolutely sealed, and in case of leakage, easy to repair using gas or electric arc welding;
2. Compared to brick and concrete, metal has relatively little specific gravity . On the one hand, this greatly facilitates the installation and connection of the sewerage system;
3. On the other hand, a light metal container, in conditions of flooded soils, will constantly strive to “float” to the surface of the earth under the influence of Archimedes’ forces, so it will have to be additionally anchored in the ground;

1. Despite all its advantages, all metal products have two significant shortcomings, thanks to which they were no longer used in the construction of sewer networks. The first disadvantage is high price metal, which is constantly increasing every year;
2. Second, and most main drawback is that unprotected ferrous metal is very susceptible to corrosion. Being underground, under conditions of exposure to aggressive wastewater, even the thickest-walled iron container can lose its tightness, and even completely collapse within a few years.

The only metal that can be used in underground systems sewerage is stainless steel, since it is absolutely not afraid of corrosion, and can withstand significant loads from a thick layer of soil. I want to say right away that it is very expensive, so it makes no sense to buy a stainless steel barrel at the market price specifically for these purposes.
It is advisable to use a stainless steel tank if you received it for free, or if you have the opportunity to purchase it for little money.

Option 2: brick storage tank

Brickwork is often used by owners of private houses to make the walls of septic tanks, storage tanks and cesspools. This method is considered the most inexpensive and simplest, since with its help you can easily build a cesspool of almost any shape and size. In addition, for its production it is allowed to use substandard, defective or broken brick left over after building a house.

Despite the fact that the cesspool has a simple and primitive design, its construction has some features that I want to talk about in this section:

1. To build the walls of cesspools, you can only use red burnt bricks because white sand-lime brick, will gradually deteriorate if left in water for a long time;

1. Before laying bricks, you need to arrange a level surface at the bottom of the pit. waterproof base . This can be a ready-made reinforced concrete slab of suitable size, or thick layer reinforced screed made of monolithic concrete;
2. For laying bricks, you should use ordinary masonry mortar from small river sand and cement grade M400, prepared in a ratio of 4:1;
3. When laying out the side walls of the filter well, starting from the third row, it is necessary to leave small gaps 20-30 mm wide between two adjacent bricks along the entire perimeter. They are needed so that clarified water filters freely through the walls into the surrounding soil layers;

1. To cover a cesspool, you can also use either a ready-made reinforced concrete slab, or a homemade poured slab made of reinforced monolithic concrete;
2. In the ceiling of each container for sewerage, you need to leave two holes, one larger, the other smaller. Larger hole will serve as an inspection pipe, and the smaller one will be used to install the ventilation pipe.

The brick has an open porous structure, so contaminated fecal water will gradually seep through the walls of the septic tank over time and poison the surrounding soil. To prevent this from happening, I advise that after constructing a cesspool, soak inner surface brick walls sodium liquid glass.

Option 3: tank made of monolithic reinforced concrete

A concrete container for sewerage can be called universal option, since it is well suited both for the manufacture of multi-chamber septic tanks and for arranging a simple cesspool. Reinforced concrete has high strength and good corrosion resistance to the effects of aggressive substances, so a concrete tank can properly serve underground for decades, without any maintenance or repair.

To manufacture concrete tanks in residential construction, you can use one of two methods, each of which has its own disadvantages and advantages.

1. In the first case, a concrete storage tank or septic tank is assembled from ready-made concrete rings for wells.
   They are produced different sizes, in addition, models of rings with a solid bottom, with locking end connections and with a closing top cover are available.

• This kit allows you to assemble in a short time concrete septic tank practically unlimited volume, with any number of individual round chambers;
• If one of the elements of a prefabricated septic tank is damaged, it can be dismantled without much difficulty and a new, serviceable element installed in its place;
• Concrete rings large diameter have significant weight, so during the construction process it will be necessary to use crane or excavator;
• To prevent the tank from leaking contaminated fecal water, joints between concrete rings must be additionally sealed;
• If the joints between the rings are not tight enough, then there is a possibility that the tank will fill from the outside with groundwater, flood water or melt water.

1. The second method involves the manufacture of a septic tank directly at the site of its installation, in the form monolithic design made of reinforced concrete. To do this, at the bottom of the pit you need to install wooden formwork, and place the reinforcement cage in it.
   Then pour in liquid concrete mortar and leave until completely hardened:

• This method allows you to make a septic tank irregular shape or complex configuration, with any number of storage or settling chambers;
• Buying ready-made concrete rings will cost much more than the cost of liquid concrete mortar, therefore, in my opinion, this option is considered more budget-friendly;

• To prepare and pour concrete mortar, the use of special construction equipment is not required, so all the work can be done with your own hands, by two or three people;
• Monolithic concrete structure, after the mortar hardens it becomes absolutely airtight, therefore does not allow water to pass through and does not require additional sealing;
• Despite all the obvious advantages, this method of building a septic tank is more complex and requires much more labor time.

All reinforced concrete products have a large specific gravity, and during the construction stage this point can cause certain inconvenience. At the same time, there is also positive sides, since a heavy sewer tank will not tend to “float” out of the ground during soil flooding or a seasonal rise in level groundwater.
For the same reason, reinforced concrete containers do not need to be additionally anchored in the ground.

Option 4: containers made of polymer materials

Currently, all kinds of plastic containers have become very popular among owners of private houses. They are sold in a wide model range, which makes it possible to choose a suitable tank of almost any size.

To understand how convenient and practical they are for use in autonomous sewage systems, below I will describe their advantages and disadvantages:

1. The most important positive quality of all products made of polymer materials is that they are absolutely not susceptible to corrosion and destruction under the influence of water, acids, alkalis or other aggressive liquids, therefore they can remain underground for an unlimited period of time;

1. Plastic containers are very convenient to use and are also very light in weight., therefore, the installation of such a sewer system does not present any difficulties at all, and can be done by one or two people;
2. Using two or three plastic tanks of suitable volume, you can quickly make a simple but effective two or three-chamber septic tank that can process liquid domestic waste from a full-fledged residential building;

1. Polymer materials themselves have insufficient rigidity, but if you look at a factory-made plastic sewage tank, it is easy to notice that its body initially has massive stiffening ribs. Thanks to these ribs, it does not swell under its own weight of water, and can withstand significant soil pressure underground.

As I already said, all plastic containers have light weight, therefore, to prevent them from floating on water-logged ground, they must be anchored during installation. To do this, you need to lay a flat concrete slab at the bottom of the pit, and before backfilling, attach a plastic tank to it through the top, at least in four points, using soft elastic belts.

Conclusion

In conclusion, I would like to remind you that the durability and reliability of any sewage tank largely depends on adherence to technology and correct installation. For example, if a sewer tank is located in the ground above the freezing level of the soil, then regardless of the material it is made of, every winter it will gradually deform and be destroyed by frost heaving forces.

To avoid such mistakes during installation, I advise you to watch the attached video in this article, and if you have any questions, I suggest discussing them in the comments.

To every home comfortable stay it is necessary to supply water and equip a sewerage system for its drainage. Most convenient option considered to be a household connection external sewerage to the central system, which is not always possible to do. In this case, sewage containers are used to collect and treat wastewater.

The sewage storage tank is a large tank equipped with two openings:

• entrance for connecting the sewer pipeline;
• hole for cleaning the container.

In most cases, such a unit is installed below ground level. This allows you to preserve the aesthetic appearance of the site and space for other purposes.

Types of containers

Storage tanks are used to equip water drainage in a modern external sewer system. Installing the device does not require specific skills, but the tank requires timely cleaning, which is carried out.

Depending on the material used for production, sewer tanks are divided into:

• metal;
• concrete.

Plastic containers

Tanks made from various types plastic are the most popular.

Plastic containers for sewerage have a number of advantages over units made from other materials:

• have a relatively light weight, which is important when installing equipment;
• most airtight. This factor is achieved due to the absence of welds;
• durable, since the material is resistant to corrosion and the negative effects of aggressive substances contained in wastewater;
• relatively low cost of the device.

Metal containers

The second place in use after plastic is occupied by metal containers for sewerage.

Such equipment is heavier than plastic. You will need to use a crane to install it. You will not be able to install a metal container yourself.

Before installation, in order to prevent wastewater from entering the ground, all connecting seams must be thoroughly treated with sealant.

In order to protect the equipment as much as possible from possible corrosion, the container is coated both inside and outside with a protective anti-corrosion material, which significantly extends the service life of the tank. Resistant paint, for example, XB-785 enamel, can be used as such a material.

Concrete containers

Currently, they are used quite rarely for sewage. This is primarily due to the properties of the material used.

Concrete quickly breaks down from strong and constant humidity. Accordingly, sewer containers made of concrete do not last long. But there are a lot of costs for installing such a unit. Due to its heavy weight, the tank cannot be installed without the use of special equipment.

Thus, for small private networks, it is advisable to use plastic sewage containers.

To install a sewer container yourself you need to:

• calculate the appropriate volume of equipment and decide on its material;
• choose the optimal location for installation;
• install and check the functionality of the system.

Calculating the volume of a sewer tank

Before installing the entire external sewer system, it is necessary to determine the volume of the sewer tank.

The amount of equipment required depends on:

• on the number of people living in the house (especially important if the capacity is calculated for country cottage, in which people constantly live);
• on the amount of wastewater (on average, one person consumes about 200 liters of liquid per day);
• from the expected period of cleaning work.

Developed by specialists universal formula to calculate the volume of the sewer tank:

V=n*x*Vday, Where

• n – period between cleaning work, measured in days;
• x is the number of people permanently residing in the house;
• Vday is the estimated volume of wastewater per person per day.

For example, 3 people permanently live in a house. It is assumed that the sewage tank will be cleaned every 30 days.

V=30 days*3 people*200 liters per day=18000 liters, that is, the tank must have a volume of at least 18 m³.

Calculating the volume of a sewer tank is quite simple. But neglecting this procedure will lead to negative consequences.

Choosing a location for installing a sewer tank

At the next stage of equipping the sewer system, it is necessary to determine the location where the tank for sewage will be located. When choosing a location, you should be guided by the following rules:

• so that the liquid can flow by gravity into the tank, the latter is located at the lowest point of the plot;
• for the convenience of cleaning the structure, roads are needed along which specialized equipment can drive;
• It is desirable that the pipeline supplying wastewater to the tank is straight. This will eliminate the need to install additional equipment, such as rotary wells;
• It is not recommended to install a sewage container near the house, as unpleasant odors may arise. Too large a distance between the house and the sewer tank will result in the need to lay a long pipeline.

The most optimal distance from the house to the unit is considered 6 meters.

Installation of sewage tank

To install a sewer tank yourself, you must:

• Dig a hole for the equipment. The dimensions of the pit should be approximately 50 cm on each side larger than the dimensions of the container.
• Place a layer of sand on the bottom to create a base for the container. If in the area where it is planned to install a sewage tank, there are predominantly clay soils And The groundwater are close to the surface, it is more advisable to make a solid concrete foundation under the tank. This will prevent the equipment from tilting, which could quickly cause the device to fail.

• Install the tank. Plastic containers for sewerage must be installed strictly horizontally. If you cannot install the unit yourself, you must resort to the help of lifting equipment.
• Connect the sewer pipeline.

• Check all joints for leaks. To do this, you need to put a large amount of water into the system under pressure.
• Fill the container with sand on all sides.
• Close the lid provided by the tank design.
• Bury, leaving a hole on the surface for cleaning the tank.

A properly selected and installed sewage container will last a long time.

The storage tank for sewerage is simple solution For household systems. Installing the tank yourself is not difficult and does not require special skills.

Suburban construction is carried out at an active pace, and not all areas under construction have central water supply and sewerage. However, given the fact that modern summer residents and property owners country houses They strive for comfort, it follows that they will install sewerage in their houses in any case and they also need irrigation water for their gardens. You should not rely only on gifts in the form of rain from nature.

Consequently, owners will be faced with the problem of storage tanks for water and sewerage. Storage tanks can perform many tasks:

• remove wastewater by concentrating it (from dachas, country houses, buildings for various purposes);
• storage tanks are also used in production in treatment facilities;
• in the chemical products industry, harmful wastewater is collected in storage tanks for later disposal;
• used for food storage.

Types of storage tanks

Tanks for collecting wastewater and other purposes are different types, types, sizes, from all kinds of materials and according to different prices. The market is flooded; any private owner or industrialist can find the following upon request:

• septic tank (with and without sensor);
• storage capacity (or reservoir) from 20 thousand to 2 thousand liters.

This technical device is designed to collect sewage waste for household needs, in order to subsequent cleaning and discharge into the soil or treatment by sewage disposal.

Most often septic tanks are used in residential buildings or industrial facilities where there is no connection to the city sewerage system.

Septic tanks have their positive sides:

• they are sealed;
• the structures are lightweight;
• long-term use;
• have good resistance to corrosion and chemical reaction.

A storage septic tank is a structure designed to collect sewage, a kind of cesspool, but improved, and also produced by industry for self-installation.

Septic tanks come with and without sensors. If the customer wishes, the septic tank is equipped with filling sensor at the specified level. When the container is filled to a certain level, the sensor gives a signal. Of course it's very convenient to use.

Septic tanks, like cesspools, periodically needs to be cleaned with the help of municipal services, so the drainage collector should be conveniently located for the access of a sewage truck, but not very close to the wells with drinking water, if any exist or are planned on the site.

When choosing the size of a septic tank for a private house or cottage, you must take into account that the average flow per person per day is 200 cu. mm, according to sanitary minimums 2.04.03−85.

Storage tanks with a volume of 2 thousand liters are produced with a diameter of 1100 mm, a length of 2100 mm, and tanks with a volume of 20 thousand liters are produced with a diameter of 3000 mm and a length of 11600 mm. That is, it is clearly visible that you can choose the most variety tank for collecting wastewater. Naturally, the larger the capacity, the more expensive it is.

Storage container - a sealed, cylindrical tank used for collection and storage Wastewater.

Use them correctly by including them in the diagram central system city ​​sewerage. In the event of an emergency, these treated wastewater can be used as reserve volume of water.

Such containers are made primarily of fiberglass and have several advantages before containers made of other materials:

• they are resistant to chemical compounds;
• do not require additional fastenings;
• withstand various seasonal changes temperatures;
• Available in different sizes;
• not very heavy in weight, which is convenient when installing them underground;
• long-term in operation (serve over 40 years);
• it is possible to order containers according to individual drawings, this does not affect their technical characteristics in further use;
• it is possible to connect several containers at once to increase the working volume;
• it is possible to manufacture a container of several sections for deeper water purification (similar to a septic tank);
• tanks can be transported using any type of transport;
• the inside of the container is smooth - this is good when drains pass through, as they will not form blockages;
• storage tanks when installed underground do not require permission from sanitary services, since they are absolutely sealed and made of very durable material;
• for containers, the type of soil has no restrictions, due to the high resistant material, from which they are made;
• storage tanks are also successfully used for watering the garden, since clean water can be stored, and being on the surface, the tank heats up in the sun, thereby warming the water;
• in conditions where there are problems with drinking water, drinking water is stored in these containers;
• containers can also be used for storing food;
• if necessary, various liquids can be transported in these containers.

Storage containers are advantageous in that they are completely isolate wastewater from getting into the soil. This is environmentally justified and therefore they are most suitable for use in sewage systems.

Requirements for the operation of storage tanks

Storage tanks are produced finished product and require fulfillment certain standards to keep them in working order:

Prices for storage tanks

An approximate list of prices for storage tanks is shown in the table:

The price is indicated for using the container underground; deepening up to 2.5 m., enter exit PVC pipes from 110 to 160 mm.

This article discusses in detail sewage containers: plastic wells, storage tanks and structures for other purposes, their features and main varieties, technical specifications, including dimensions. The text contains all the necessary information to familiarize yourself with a brief overview existing assortment on the market, prices for products and rules for their selection, as well as further maintenance after installation.

Construction of a house in a country village or on a summer cottage is accompanied by additional costs for arranging a water supply system and, since centralized systems are absent in such an area. The easiest way in this case is to buy a barrel for sewerage or another type of storage type structure where all wastewater will be discharged.

These containers are safe for environment and are completely sealed, but at the same time they require regular maintenance, which consists of cleaning the tank from sediment. Installation internal sewerage in a private house is no different from installing a similar system in an apartment multi-story building. The only thing the owner will have to think about is suburban area- This is the process of recycling wastewater.

Most often, the storage tank is a cylindrical tank. It is equipped with a pipe designed to collect liquid and which is used for wastewater treatment. The supply pipe leading out of the house at an angle is connected to the pipe. When the tank is filled, it is cleaned through the neck.

Helpful advice! To save money and do without earthworks, you can install the storage structure on the surface. But in this case it will be spoiled appearance plot, so for aesthetic reasons it is better to hide the septic tank underground.

Advantages and disadvantages of storage septic tanks, their application

Main functions of storage structures:

1. Collection of waste and drainage from the side of a residential building.
2. Storage of wastewater for a certain period.
3. Providing comfort for the residents of the house.
4. Keeping the surrounding area clean.

The use of storage tanks to collect wastewater has both advantages and disadvantages.

Why is it profitable to buy a sewerage tank with storage function:

• a simple installation system that allows the summer resident to carry out installation work with his own hands;
• environmental safety and no risk of environmental pollution due to the tightness of the structure;
• the price of a plastic storage tank for sewage is significantly lower than the cost of building a septic tank based on other materials or an autonomous station designed for biological wastewater treatment.

The only disadvantages of such structures include the need for regular cleaning using specialized equipment. The frequency of such maintenance depends on the capacity of the tank, as well as the amount of drainage.

Which is better to buy a storage tank for sewerage: types of structures, their features

The offered range of containers intended for collecting sewage includes products of various modifications and sizes. General classification Such designs are based on the material of manufacture. It is he who determines the cost of the product, its technical and performance characteristics, properties and installation features.

Concrete structures are used extremely rarely. This is primarily due to the limited service life of a product made from this material and installed in the ground. Concrete is vulnerable to moisture, which causes its rapid destruction. In addition, the installation of such a container is accompanied by many difficulties and requires the use of heavy construction equipment.

Metal structures are also not highly reliable, although they are used much more often than concrete products. This material is subject to corrosive destruction under the influence of aggressive environments and water.

Helpful advice! If you are going to buy a metal sewer container, it is better to give preference to products that have a protective coating, both internal and external. In addition, all seams and joints must be filled with sealant to prevent contaminated wastewater from entering the soil.

The most optimal option for a summer cottage would be to buy a plastic sewer tank. These designs have many advantages compared to previous options:

• the material is not at all afraid of corrosion and does not react to the negative effects of aggressive environments;
• the product is light in weight, which simplifies the transportation and installation system, and also eliminates the use of special equipment;
• The container is monolithic, due to the absence of seams, and sealed.

Using sealant, you will only need to treat those areas where the plastic septic tank for sewage is connected to the pipe.

Sewage containers: plastic wells, their variety

A sewer well is a sealed structure that allows wastewater to flow through the system with minimal resistance.

The structure of such system elements is the same:

• bottom, equipped with or without a tray;
• shaft or extension section;
• cover or .

Recommended installation locations for wells apply to areas with relief differences in the area, at the entrance or exit of the main line, as well as pipeline branches. Installation of these elements in other places is also allowed if this is consistent with the system diagram and does not contradict the calculations.

The following types of wells are distinguished by purpose:

• distribution;
• examination rooms;
• drainage or storage.

In addition, the use of plastic wells for cable ducts is widespread. In this case, a network of communication cables runs underground, which are protected by a system of tunnels from the influence of groundwater and other destructive factors.

Externally, sewer wells produced by different manufacturers, have virtually no differences. The variability lies only in the size, the system of elevations where the exits and entrances are located, the absence or presence of a flow speed damper, and some technical features. The shaft of the structure is made in the form of a corrugated pipe.

The shape of the tray can be different:

• angular;
• cross;
• straight bore;
• trigeminal.

Helpful advice! To ensure the tightness of the well, it is recommended to use rubber seals.

Features of inspection and distribution plastic wells for sewerage, price

Viewing elements are installed in the most vulnerable areas of the system and are used to monitor its condition.

Such places include:

• side line joints;
• depth changes;
• zones where the diameter of the pipeline, its slope or direction changes.

The tray part, located at the very bottom, most often has a diameter of 80 cm. Here is the outlet and input of pipes, the diameter of which is in the range of 110-160 mm. The shaft is formed on the basis of extension sections 50 cm long. O-rings, pre-treated with silicone.

The main function of a distribution well is to regulate the movement of fluid flows within the drainage system, stormwater or domestic sewage system. This procedure is carried out naturally due to design features products.

The distribution well consists of the following elements:

• a tray with a high safety margin, equipped with ring-type stiffeners;
• neck;
• screw cap ensuring tight closure of the well.

In general, the design is reliable and airtight, thanks to durable fasteners and O-rings.

Properties of plastic storage wells for sewerage

Cumulative or drainage well is considered the most difficult element to install, despite standard structure in the form of a tray, cover and main sections. Its installation is carried out at the lowest point of the site where water will flow.

The storage well is filled from various sources:

• treatment facilities;
• drainage system;
• storm drains;
• septic tanks

But in terms of operation, such designs are simple. They do not require frequent cleaning.

Helpful advice! To construct storage wells, it is better to use solid bases with adjustable volume due to extension sections. The water that accumulates in the structure over time can be used for economic purposes, for example, for filling a reservoir or watering plants. In this case, you cannot do without a pump.

Features of polymer sand wells for sewerage

A prefabricated polymer sand well for sewerage is made on the basis of polymer raw materials with a small addition of sand. The structure is formed using the tongue/groove method from polymer rings. Thanks to this, the elements of the well fit together as closely as possible, so there is no need for additional sealing. Seams can be treated with silicone.

The bottom is used as the basis. The structure itself is made up of rings, and the upper one should have the shape of a cone, where the closing hatch is installed. The cost of such wells is quite high, but there is an opportunity to save on installation work and further operation.

Advantages of polymer sand products:

• reliability and high safety margin;
• lightweight (maximum weight of any part does not exceed 60 kg);
• high resistance to static and mechanical loads;
• long service life (up to 100 years);
• convenient service system;
• simple transportation and installation system;
• high resistance to negative impact moisture and low temperatures.

Price of polymer rings for sewers, bottoms and cones Polex Plast:

Polymer sand well structures are universal and can be used for various purposes. They are able to withstand pressure up to 0.4 tons.

Buying the optimal plastic container for a septic tank for sewerage: price of products

On the market building materials You can buy plastic containers for sewage of various sizes and modifications. To create them, special production technologies allowing to obtain products with improved characteristics. Such material is capable of withstanding severe tensile or compressive loads, which makes it possible to use polymer septic tanks without fear that the soil may damage or deform the container during heaving and movement.

Why is it profitable to buy a plastic sewer container for a septic tank:

• the lightweight structure allows transportation using a regular car;
• a simple installation system does not require the participation of specialists; the installation of a septic tank can be handled by two people;
• low cost of the product;
• inertia towards negative influence aggressive environments, due to which the effective operational service life is measured in tens of years.

Helpful advice! In order to reliably and efficiently install a plastic waste container, be sure to anchor it to concrete slab. In addition, you will need to create a clay or concrete backfill around the container. Thanks to this, the septic tank will remain in its place, and will not float like a float in the soil.

Among the disadvantages of plastic waste containers, one can note their fragility under the influence of low temperatures. For this reason, experts recommend backfilling when installing a structure using insulating material.

Features and price of plastic containers for sewage: polypropylene products

Polypropylene is made from polymers. Despite the similar basis, this material is much stronger than plastic, due to the inclusion of softening substances in the composition that increase plasticity.

The unique composition provided polypropylene products many advantages:

• resistance to temperature changes;
• resistance to cracking due to temperature changes;
• long service life (about 100 years);
• tightness and waterproofness, thereby eliminating the possibility of contamination of water sources by wastewater;
• high resistance to the influence of steam during system sterilization and exposure to aggressive environments.

Products made of polypropylene have thick walls ranging from 5-20 mm. In addition, the design provides for the presence of stiffeners. These elements prevent the tank from floating and provide additional strength.

Polyethylene products are made from polymers with the addition of fiberglass threads. Thanks to this, the walls perfectly withstand such negative phenomena as soil movement and swelling. Containers respond well to stretching and smooth compression, but they are afraid of sharp impacts. Forceful impact can damage the tank and cause a crack to appear.

Advantages of polyethylene septic structures:

• light weight of the product;
• a wide choice of configurations, including spherical and square shapes;
• long service life (within 30-50 years);
• resistance to the negative influence of aggressive environments.

Like others plastic products, polyethylene containers are easily damaged under the influence of sudden mechanical loads.

Helpful advice! The storage volume should be selected taking into account the fact that one person needs approximately 1 m³. Thus, for a family of 4 or more people, you will need to buy a plastic sewer container of 5000 l or 5 m³.

Selection of additional equipment for sewage treatment plants

To clean household wastewater in a private home, septic tanks, autonomous sewers and other types of structures are used.

There are two types of waste:

1. Black - drains from the toilet.
2. Gray – waste liquid from the kitchen, bathroom, sink and household appliances, for example, a dishwasher or washing machine.

Sewage waste accounts for about 30% of the total volume of wastewater. Most often, waste liquid comes from the bathroom and sink. On average, one person consumes about 160-200 liters of water per day. In most cases, mechanical and biological method cleaning, since these technologies are considered the most practical, safe and affordable.

Cost and features of a sewer riser in a private house

The sewerage system consists not only of a pipeline and a storage tank. For the system to function effectively, additional communication equipment will be required in the form of fan boner. Such a pipe serves as a connecting element between the common highway and the atmosphere. The main task of the fan riser is to provide ventilation within the system.

Installation of a drain pipe is necessary in the following cases:

• sewer system autonomous type is located near a residential building;
• the house has two or more floors with sewerage and water supply;
• the diameter of the sewer risers is in the range of 50-110 mm;
• exploitation country house is accompanied by the simultaneous release of a large amount of wastewater, for example, if there is a swimming pool or other type of water equipment on the site.

Fan pipes can be rigid, sliding, angular or straight. Some of them are equipped with a clamp, extensions or transition parts.

Important! Fan pipe should rise above the roof by at least 50 cm. The optimal diameter of the elements is 110 mm, although the use of parts of other sizes is allowed. The pipe installation should be done on the leeward side. In this case, it is advisable to focus on the wind rose.

Why you need to buy a sewer pump: prices and equipment features

The sewer system organized at a summer cottage cannot function normally without regular cleaning of storage tanks or running wastewater towards the central collector. To effectively perform these tasks, experts advise purchasing fecal pumps for pumping out sewage. These devices represent a broad category of units, each of which is focused on specific operating conditions.

Based on the type of installation, the following types of pumps are distinguished:

• superficial;
• submersible type;
• semi-submersible devices;
• semi-submersible fecal units;
• pumping units for domestic use.

Having decided on a certain type of installation, you should first pay attention to operating voltage pump Most often, summer cottages are powered from a 220 V network, but there are also systems with three phases. For such cases, it is recommended to buy equipment rated for 380 V. The power level when choosing a pump is also important. In most cases, such equipment is operated under high load conditions, so it is rare to find a unit whose power is less than 400 W.

What is the name of the sewer pumping machine and features of its use?

Special equipment designed to empty the sewer system at a summer cottage and remove waste for disposal is called a sewer truck. This type of equipment is used to clean cesspools, septic structures, and overgrown bodies of water, such as ponds. The equipment installed on the vehicle is completely sealed. Due to this, wastewater disposal is carried out in a safe manner.

The complete set of the sewer truck consists of the following elements:

• powerful pump;
• storage tank;
• hose;
• signaling device;
• pipes.

There are several varieties of such machines, which differ in the principle of suction of wastewater. In one version, the drainage of the sewer is carried out using a suction manifold on the motor, in another version a pump is used vacuum type. Sludge disposal machines have appeared relatively recently, which, in addition to pumping out liquid, are capable of removing sludge deposits.

Note! The capacity of the sewage disposal machine is filled within 4-12 minutes. This depends on the capacity of the storage tank.

How do sewer pumping machines work in a summer cottage?

The operating principle of sewage disposal machines is quite simple. Pump equipment creates a vacuum in the container, as a result of which the waste liquid is sucked through the hose. This process is completely controlled by special sensors. When the storage tank on the vehicle is filled to the limit line, the equipment sends a corresponding signal.

To without unnecessary problems To pump out a sewer in a private house, you need to call a machine with the appropriate technical characteristics. This type of equipment may have different parameters volume, working capabilities, dimensions. There are no generally accepted standards, so it is better to call a technique designed to empty a septic tank of a certain volume. The capacity of sewer trucks varies between 3-15 m³.

Operating capabilities reflect the pump's power level, pump stroke length, and wastewater suction speed. In most cases, you can limit yourself to calling a small car, for example, GAZ. If the sewer system at the dacha is large enough, as is the capacity of the septic tanks, in such cases it is recommended to call a KAMAZ vehicle.

The design of the machine may contain additional elements, due to which opportunities are expanded. Some modifications of sewage disposal machines are equipped with two barrels or have a water tank.

How to pump out a sewer in a private house: price for services

If you clean your sewer system in a timely manner, you can save money on repairs in the future. The smaller the capacity of the car, the cheaper the pumping services will cost. The smallest tank is equipped with GAS, its capacity is 2 m³. This type of sewer truck is capable of pumping out one. In most cases, summer residents use the services of GAZ with a tank capacity of 4 m³.

Important! A vehicle with a capacity of 4 m³ or more should be able to drive as close as possible to the pumping site. Maximum permissible distance is 16 m from the hatch.

The cost of sewer pumping services depends on the following factors:

• volume of wastewater that needs to be pumped out;
• remoteness of the summer cottage;
• depth of the storage tank;
• features of the approach to the pumping hatch, its remoteness;
• working hours;
• additional procedures that the customer wants to carry out.

The average cost of pumping out 1 m³ of wastewater and then transporting it for disposal is about 300 rubles. The minimum volume of work for one call is 4 m³. The price of 1 hour of operation of sewage disposal equipment is about 1800 rubles.

In what cases is it necessary to call special equipment:

• the tank is full and there is an unpleasant odor in the area;
• the pressure in the taps has dropped;
• liquid in plumbing system rusty;
• cloudiness of the water in the well is observed;
• The storm drain system is clogged or does not perform its function well.

The comfort and service life of the sewer system is influenced by many factors. For this reason, it is very important to correctly calculate the system parameters and select the appropriate elements. Moreover, not only the quality of installation matters, but also timely care sewerage, cleaning and maintenance. Only in this case can the system last the entire period declared by the manufacturer.

In places where there is no centralized sewer system, special sealed containers are used to solve the problem of collecting and storing household wastewater. They are also used in production as storage tanks for industrial and chemical waste.

This article will tell you about the features of the structure, installation and operation of sealed sewer tanks.

Most often, containers are used for sewerage in order to save space on local area, as well as for reasons of aesthetics, are installed underground. Their size is directly dependent on the expected volume of wastewater and the planned frequency of emptying the tanks.

Usually, all modern country or country houses have centralized water supply, therefore, the issue of disposal of used water and other sewage waste is very relevant. It is best to begin sewer construction at the stage of building a house.

If the sewerage installation was not started in a timely manner, this will subsequently create some difficulties.

In terms of its structure, the sewer system in a country house is not much different from the one that operates in city apartments. The only and main difference is that wastewater is not disposed of centrally, but on its own, privately.

Sewage system options

In a private home, the most common sewerage solutions are:

• Storage tank;
• Cesspool;
• Septic tank;
• Local wastewater treatment plants(LOK).

Each of these methods of sewerage arrangement has its own characteristics. And, when choosing the most suitable one, you should take into account such nuances as the geological features of the area, the parameters of the land plot, the amount of drains, as well as the number of residents of the house. Septic tank

Helpful information! Of the above methods, the most accessible and has been very popular among the population for a long time is the cesspool. However, from an environmental point of view this is not the best option, since wastewater from the cesspool can partially leak into the environment.

Installation of an autonomous sewerage system (another name is a septic tank), in view of its high price, today not everyone can afford it. Moreover, often one such container is not enough for a complete sewage system. In addition, water purified in a septic tank then needs to be further purified in a drainage field.

LOCs are miniature analogues of urban wastewater treatment plants. The water purified with their help is suitable for technical and irrigation work on the site. But this cleaning method has its drawbacks - high cost and dependence of the LOC on electricity.

If the house is located within an urban area or the groundwater level in the area is high, then in this case it is impossible to install sewage treatment plants. The solution in this situation is to use sealed containers for sewerage. When installing such a container, it is important to choose a place for its location that will be convenient for a sewer truck to drive up to remove waste.

Arrangement of an individual sewer system in a private house

Installation of a sealed storage tank - perfect solution for the arrangement of an autonomous sewer system for a private house. It allows you to reliably isolate waste and wastewater, thereby preventing their release into the environment.

The inconvenience of such a sewer system is the need to empty it through drain holes. The frequency with which this procedure must be repeated depends both on the volume of the tank itself and on the wastewater entering it.

Advice! If 4-6 residents live in a house, then the optimal volume of sewer tank for the needs of such a family will be 10-12 m?.

In addition to this advice, it is also worth taking into account the individual needs of those living in the house (how much water is used per day for bathing and other needs).

Cottages and other large houses, as a rule, require storage tanks from 5 to 15 thousand liters.

For ease of use, there are models of sewer tanks equipped with a sensor that controls filling. When the container is filled to a state close to full load, the sensor signals this.

Often the sewer system is one with the storage tank. A properly installed container can serve your family as a sewer for many years. The tank has two pipes, one for filling with wastewater, the other for draining it.

Moving through the receiving pipe, wastewater enters the storage tank, where it is subsequently stored. There is usually a maintenance hole on the top of the container through which waste is pumped out as needed.

Sometimes there may be a maintenance well instead of a hole. Sewage water is pumped out of the tank using sewer trucks, special pumps or other auxiliary equipment.

Maintenance of sewage storage tanks

As a rule, the only type of maintenance that storage containers require is their timely emptying.

The kit for installing an individual sewerage system includes:

1. Storage container (made of plastic or metal);
2. Service openings;
3. Covers for maintenance holes;
4. Pipes for supply and drainage of wastewater;
5. Technological supports required for tank installation;
6. Fill level sensor (installed at customer's request).

Choosing a location for a storage tank, basic recommendations:

1. You should take into account the slope of the terrain and install the container below the level of the house.
2. Make sure there is a convenient access road (4-5 meters wide) to the sewer tank for supplying sewage equipment.
3. It is preferable to place the tank near the house (distance up to 5 m). If this is not possible, then it is necessary to equip the sewerage system with additional wells to allow engineering works, for example, removing blockages.
4. If you have installed a fullness control sensor on a container, a signaling device from it must be placed in the house so that you can monitor its readings and not miss right moment for pumping out sewage water.
