Sewerage tanks: plastic wells and storage tanks

This article discusses in detail the tanks for sewage: plastic wells, storage tanks and structures for other purposes, their features and main varieties, technical parameters, including dimensions. The text contains all the information you need to get acquainted with a brief overview of the assortment available on the market, prices for products and rules for their selection, as well as further service after installation.

General information about storage tanks for sewage

The construction of a house in a suburban village or in a summer cottage is accompanied by additional costs for the arrangement of water supply and sewerage systems, since there are no centralized systems in such an area. The easiest way in this case is to buy a sewerage barrel or another type of storage-type construction, where all wastewater will be discharged.

Such tanks are safe for the environment and completely sealed, but at the same time they need regular maintenance, which consists in cleaning the tank from sediment. Installing an internal sewerage system in a private house is no different from installing a similar system in an apartment in a multi-storey building. The only thing the owner of a suburban area will have to think about is the process of waste disposal.

Most often, the storage tank is a cylindrical tank. It is equipped with a branch pipe for collecting liquid and wellwhich is used for wastewater treatment. The supply pipe leading from the house at an angle is connected to the branch pipe. When the tank is full, it is cleaned through the neck wells.

Helpful advice! To save money and do without earthwork, you can mount the storage structure on the surface. But in this case, the appearance of the site will be spoiled, therefore, for aesthetic reasons, it is better to hide the septic tank under the ground.

Advantages and disadvantages of storage septic tanks, their use

The main functions of storage structures:

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

The use of storage tanks for waste collection has both advantages and disadvantages.

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

• a simple installation system that allows the summer resident to do the installation work with his own hands;
• environmental safety and no risk of environmental pollution by waste, 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 disadvantages of such structures can be attributed only to the need for regular cleaning using specialized equipment. The frequency of this service depends on the capacity of the tank as well as the amount of effluent.

What is better to buy a storage tank for sewage: types of structures, their features

The offered assortment of containers for collecting sewage includes products of various modifications and sizes. The general classification of such structures is based on the material of manufacture. It is he who determines the cost of the product, its technical and operational characteristics, properties and installation features.

Concrete structures are rarely used. 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 provokes 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 undergoes corrosive destruction under the influence of aggressive media and water.

Helpful advice! If you have to buy a container made of metal for a sewer, 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 a sealant that prevents contaminated runoff from entering the soil.

The most optimal for a summer cottage will be the purchase of a plastic tank for sewage. These designs have many advantages in comparison with the previous options:

• the material is absolutely not afraid of corrosion and does not react to the negative effects of aggressive media;
• the product is lightweight, which simplifies transportation and installation system, and also excludes the use of special equipment;
• the container is monolithic, due to the absence of seams, and is sealed.

With the help of a sealant, it will be necessary to treat only those areas where the plastic septic tank for sewage is connected to the pipe.

Sewerage tanks: plastic wells, their species diversity

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, complete with or without a tray;
• shaft or extension section;
• cover or Luke.

Recommended installation locations of wells apply to places of relief differences in the site, at the entrance or exit of the main, as well as branching of the pipeline. Installation of these elements is also allowed in other places, if it is agreed with the system diagram and does not contradict the calculations.

Wells of the following types are distinguished by purpose:

• distribution;
• viewing;
• 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, sewage wells produced by different manufacturers have practically no differences. The variability lies only in the size, the system of elevation marks where the exits and entrances are located, in the absence or presence of a flow velocity damper and in 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 through;
• threesome.

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

Features of inspection and distribution plastic wells for sewage, price

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

These places include:

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

The trough part, located at the very bottom, most often has a diameter of 80 cm. Here there is an outlet and an inlet of pipes, the diameter of which is in the range of 110-160 mm. The shaft is formed on the basis of 50 cm long extension sections. Sealing rings pretreated with silicone are used as a fixing element for connecting the sections.

The main function of the distribution well is to regulate the movement of fluid flows within the drainage system, stormwater or sewage system for household purposes. This procedure is carried out in a natural way due to the design features of the product.

The distribution well consists of the following elements:

• a tray with a high margin of safety, equipped with ring-type stiffeners;
• necks;
• screw cover to ensure tight closure of the well.

In general, the design is reliable and sealed, thanks to strong fasteners and O-rings.

Properties of storage plastic wells for sewage

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

The storage well is filled from different sources:

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

But in terms of operation, such structures are simple. They don't need frequent cleaning.

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

Features of polymer sand wells for sewage

Prefabricated polymer sand well for sewage is made on the basis of polymer raw materials with a small addition of sand. The structure is formed by the tenon / groove method from polymer rings. Thanks to this, the elements of the well adhere to each other as tightly as possible, so there is no need for additional sealing. Treatment of seams with silicone is allowed.

The bottom is used as a 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 it becomes possible to save money on installation work and further operation.

Advantages of polymer sand products:

• reliability and high safety margin;
• light weight (the 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 the negative effects of moisture and low temperatures.

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

On the building materials market, you can buy plastic containers for sewerage of various volumes and modifications. To create them, special production technologies are used to obtain products with improved characteristics. Such material is able to withstand severe tensile or compression loads, which makes it possible to use polymer septic tanks without fears that the soil during heaving and movement can damage or deform the container.

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

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

Helpful advice! In order to safely and efficiently carry out the installation of a plastic container for drains, it is imperative to anchor it to a 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 place, and not float like a float in the soil.

Among the disadvantages of plastic containers for wastewater can be noted their fragility under the influence of low temperatures. For this reason, experts recommend backfilling when installing a structure using insulation material.

Features and price of plastic containers for sewage: polypropylene products

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

The unique composition provided polypropylene products with many advantages:

• resistance to temperature extremes;
• resistance to cracking due to temperature changes;
• long service life (about 100 years);
• tightness and waterproofness, thereby eliminating the likelihood of contamination of water sources by drains;
• high resistance to steam during system sterilization and aggressive media.

Polypropylene products are endowed with thick walls in the range of 5-20 mm. In addition, the design provides for the presence of stiffeners. These elements prevent the tank from floating and provide additional strength.

Features and price of plastic septic tanks for sewage: polyethylene products

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 sudden impacts. Force can damage the reservoir and cause a crack.

Advantages of polyethylene septic structures:

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

Like other plastic products, plastic containers are easily damaged under the influence of sharp mechanical stress.

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

Selection of additional equipment for sewage treatment plants

To purify household wastewater in a private house, septic tanks, autonomous sewerage systems and other types of structures are used.

There are two types of effluents:

1. Black - toilet drains.
2. Gray - Waste liquid from the kitchen, bathroom, sink and household appliances such as a dishwasher or washing machine.

Sewage waste accounts for about 30% of the total wastewater volume. Most often, the waste fluid 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 cleaning methods are used to clean the system, since these technologies are considered the most practical, safe and affordable.

The cost and features of a fan sewer riser in a private house

Sewerage consists not only of a pipeline and a storage tank. For the effective functioning of the system, additional communication equipment will be required in the form of a fan riser. Such a pipe serves as a connecting element between the common line and the atmosphere. The main task of the funnel is to provide ventilation inside the system.

Varieties of products, their features and sizes, prices. Recommendations for choosing pipes and organizing a drain based on them with your own hands.

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

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

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

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

Why do you need to buy a pump for pumping out sewage: prices and equipment features

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

By the type of installation, the following types of pumps are distinguished:

• superficial;
• submersible type;
• semi-submersible devices;
• semi-submersible fecal aggregates;
• household pumping units.

Having settled on a certain type of installation, first of all, you should pay attention to the operating voltage of the 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 designed for 380 V. The power level when choosing a pump is also important. In most cases, such equipment is operated under high loads, so it is rare to find a unit with a power less than 400 watts.

Average price of fecal pumps for pumping out the Jileks sewage system:

Modification	Height of water rise, m	Depth, m	Power, W	price, rub.
Tugunka 140/6 5400	6	8	250	3300

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

A special technique designed to empty the sewer system at a summer cottage and take waste for disposal is called a sewer machine. This type of equipment is used for cleaning cesspools, septic structures, as well as overgrown water bodies, such as ponds. The equipment installed on the vehicle is completely sealed. Due to this, waste disposal is carried out in a safe mode.

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

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

There are several types of such machines, which differ in the principle of suction of waste water. In one embodiment, the draining of the sewer is carried out using a suction manifold on the motor, in another version, a vacuum pump is used. Relatively recently, sludge suction machines have appeared, which, in addition to pumping out liquid, are able to eliminate sludge layers.

Note! The capacity of the sewer truck is filled within 4-12 minutes. It depends on the capacity of the storage tank.

How do sewer pumping machines work at their summer cottage

The principle of operation of sewage trucks is quite simple.The pumping equipment forms a vacuum in the tank, as a result of which the waste liquid is sucked in through a hose. This process is completely controlled by special sensors. When the storage tank on the vehicle fills up to the limit line, the equipment sends a corresponding signal.

In order to pump out the sewage system in a private house without unnecessary problems, you need to call a car with the appropriate technical characteristics. This type of equipment can have different parameters of volume, operating capabilities, and overall 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 sewage trucks varies between 3-15 m³.

Operational capabilities display pump power level, pump delivery length and wastewater suction rate. In most cases, you can limit yourself to calling a small car, for example, GAZ. If the sewage system at the summer cottage is large enough, like the capacity of septic tanks, in such cases it is recommended to call a KAMAZ car.

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

How to pump out the sewage system in a private house: the price of services

If you clean the sewer system in a timely manner, you can save on repairs in the future. The smaller the car's capacity, the cheaper the deflation service will be. The smallest tank car is equipped with GAZ, its capacity is 2 m³. This type of sewage machine is capable of handling the pumping of one concrete ring... In most cases, summer residents use the services of GAZ with a tank capacity of 4 m³.

Important! A machine with a capacity of 4 m³ or more must be able to drive as close as possible to the pumping point. The maximum distance allowed is 16 m from the hatch.

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

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

The average cost of pumping 1 m³ of wastewater with subsequent removal for disposal is about 300 rubles. The minimum amount of work for one call is 4 m³. The price of 1 hour of work of the sewage equipment is about 1800 rubles.

In what cases a call for special equipment is required:

• the tank is full and an unpleasant odor appears on the site;
• pressure dropped in the taps;
• the liquid in the plumbing system is rusty;
• there is a cloudy water in the well;
• the stormwater drainage system is clogged or poorly performing its function.

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