Cities are developing rapidly, industrial enterprises are equipped with new equipment, but problems continue to remain. Therefore, it is necessary to design sewage pumping stations and install them. The demands placed on them are high, because a breakdown will provoke flooding of nearby areas. It is necessary to accurately calculate the water supply level, the type of pumps, as well as their number.
Connecting the pump to the pipes is not that difficultThe KNS level sensor controls. The supply should be determined based on the water inflow to the station.
b) Sewage pumping station 250 sanivort. Removes wastewater discharged from sinks located below the level of the sewer system collector. It is convenient to install it where there is no possibility of gravity drainage.
Complied with. The body material is safe, because it is plastic and is easy to clean. Pumping is controlled by a sensor. The station is equipped with ventilation.
c) Sewage pumping station sanivort 600 - pumps wastewater containing feces. Thanks to it, it is possible to organize water pumping in remote places. Nothing but feces and toilet paper must not be. Liquid temperature up to +40C. Pumping of sewer stations is carried out quickly, because the system’s power is high - 600W. Up to 80 liters are pumped per minute.
On modern market huge selection of electric pumpsThe station is suitable for toilets with a horizontal outlet and a flush barrel volume of at least 6 liters.
d) Sewage pumping stations grundfos station easy to operate and do not require additional maintenance. Station pumps are well suited for high-pressure sewers. Additional systems management will provide reliability and efficiency.
d.) Modular pumping station is a fully factory-ready product. It includes a fully assembled and finished equipment. Installation of a sewage pumping station depends on its purpose. The number of pumps is set based on the same. A block box is being constructed for the station in which it will be located. Pumping stations are designed at the factory. They contain automatic system control. In case of an accident or lack of electricity, it will work in automatic mode for a long time.
Not suitable for household Wastewater, its main purpose is to work with drinking water supply.
E) Fecal pumping stations— equipment that allows pumping domestic wastewater, both in private homes and in neighborhoods. When ordering it is important to consider specifications. Stores often offer to choose the necessary equipment yourself. You can get advice on it from the manager. This is a big plus for those who do not understand this.
The main factors influencing cost and characteristics:
The fecal station differs from the others in that the waste liquid entering the system is not uniform in volume and time. Therefore, such reservoirs act as “settlers”. Sediment accumulates in them and releases bad smell. But the danger is that harmful gases accumulate. The main task of each tank is to create an environment for the normal operation of pumps.
Pumping stations modern type can be installed on new and old sewer systems.
Superficial sewerage installation has more power. After all, it is not limited in size and can pump liquid in large volumes. There are two types of such pumps - diesel and electric.
Many people are concerned about the question of whether it is possible preventative work carry out independently. The answer is a clear no. Servicing of the pump is performed exclusively by specialists. Working mode. Service maintenance includes a number of planned mandatory activities. For example, waste collection baskets are installed for use. They need to be cleaned periodically. Only experienced people can do this.
Modern diversion stations are now being produced. They are produced in a modular version and are made of plastic. The factory is engaged in their production.

Due to the plastic body, the station is light in weight. Thanks to this, installation work is easier, and the service life of the products does not change. In complex stations, the equipment is located inside. The construction of ground structures is no longer necessary.
Thanks to penetration modern technologies in various areas, today it is possible to solve many problems at lower costs. And the implementation of some tasks has become easier. The installation of a sewage pumping station is an opportunity to ensure the transportation of wastewater from a private home or office. Thanks to this equipment, a solution to the main problem is provided - the absence of a slope for effective wastewater drainage.
It is not always possible to transport used water and sewage from buildings by gravity due to the lack of slope. If it is absent or very small, then the use of natural drainage when discharging sewage can lead to clogging of the system. The same result can be counted on when the system contains small cross-section pipes. Clogging of the sewer occurs when inclusions such as:
Their presence leads to a decrease in the efficiency of washing off fats and other deposits from the pipe walls. Therefore, to ensure effective wastewater disposal, the most The best decision– installation of a sewage pumping station. Its use in private homes and offices for drainage has several advantages:
If the owner decides to install a water pumping station for effective wastewater disposal, then when choosing it it is necessary focus on the following parameters:
Modern CNS are of two types:
If we talk about compact-sized SPS equipped with a level sensor, then, in fact, they are small-sized devices that produce a minimum noise level during operation. They can be installed directly behind the toilet or washing machine. Depending on the required power, the sewer station may have several receiving pipes and one outlet valve.
Currently popular models of QNS are those with large toilet entrance and several washbasins. Their installation can be carried out in any premises where difficulties arise with the transportation of wastewater. For example, if drainage points are located below the level of the sewer main, then in such cases the only possible and the right decision is the installation of a pumping station. The use of such equipment provides the opportunity to minimal costs arrange the bathroom and kitchen.
Included in the pumping station includes three components:
IN modern models KNS main details made from polymer materials. This makes it possible to eliminate the occurrence of corrosion processes on their surface. When constructing such a system, it is installed in the ground at a certain depth or in a shaft equipped in a special way.
Depending on the requirements of the owner, as well as the characteristics of the object, the equipment of the pumping station may include two pumping units. This option is chosen when a pumping station is installed in a private house. If it is located in office space or in an industrial plant, it can include up to 5 pumps.
For domestic purposes, several are most often used different types pumps and various mechanisms. Experts recommend using pumps to create a sewerage station, having a cutting edge, thanks to which the clogging of the system by large pollutants stops. The use of such solutions in industrial enterprises can lead to the pumping station failing when solid inclusions from plastic and concrete enter it.
When performing work on the installation of such pumping stations, they are guided by requirements of SNiP 2.04.01-85. This document records:
The sewage pumping station should be located at general level. In this case, the most effective technique drains. When a sufficient quantity of wastewater has accumulated in the station’s tank and the sensor is triggered, wastewater is released to the disposal site. The peculiarity of this process involves installing the reverse sewer valve. It is necessary to prevent the water column from returning to the receiver.
Alarm systems High-performance sewage pumping stations can be equipped. It will operate in cases where the incoming volume of wastewater cannot be handled by the equipment used in the systems. pump equipment. Also, the alarm will be triggered in the event that the installations fail. Some stations may include temperature level sensors, and in addition, meters of the pumped volume of wastewater.
To provide uninterrupted operation drainage systems and pumping stations can be equipped with a backup power source. Due to the fact that the power of the pumping station is quite high, and the starting currents for pumping equipment are required to be quite high, it is necessary to install a powerful battery. Therefore, when choosing a power source for the KNS, use gasoline generators or units operating on diesel fuel. In this case, even in the event of an emergency power outage, the station will operate as usual.
As part of a high-performance pumping station there is a filtration system, which is represented by a pre-cleaning capacity. Heavy fractions, as well as large objects, accumulate in it. They are there before they enter the pumping chamber. Such designs usually provide a hatch through which people, using a shovel, ensure effective cleaning of the receiver. For the reason that not only household waste, but also wastewater, for efficient work equipment, it is necessary to clean the receiver once a month.
Although sewerage stations in private homes and offices began to be used not so long ago, nevertheless, there is already a big choice alternative options, which are effective and at the same time affordable. One of them - submersible drainage sewage pumps. The main purpose of this equipment is to pump water from basements from the ground floor. These pumps can also be used to pump out wastewater from cesspools.
If you purchased such equipment, then with a little modification you can make a sewer station on your own. To do this, you only need to purchase a container from polymer material and some plumbing equipment:
Models of sewage stations based on fecal drainage pumps are currently available on the market. They are offered in a wide range. Among the models offered you can find installations equipped with cast iron knives. Some models have cutting edges made of stainless steel and steel. The performance of these systems varies greatly, so you can choose suitable option to your home or office.
Not in all cases, when creating a sewer system, it is possible to install a well or bury a container to drain wastewater into the ground. In such cases, the solution to the problem is to install a water pumping station. With their help, even from a building that has a sewer system with a slight slope of pipes, it is possible to ensure effective removal of used water and wastewater. Offered on the market large selection of models pumping stations. They vary in cost, performance and size. Therefore, every owner of a private home or office can choose the appropriate equipment.
Often, owners solve the problem of draining wastewater from a building by means of a device ground floor containers for temporary storage of wastewater. Here the best option would be to use a sewer console type stations. In such cases, the container is installed in cabinet furniture in the basement. The dry installation method is used, which eliminates damage to walls or floors during the work. After this, you can connect plumbing fixtures, washing machine and use them without experiencing any problems with the disposal of used water and wastewater. All wastewater will be efficiently drained from the building and then pumped to the recycling site.
A sewage pumping station (SPS) is a complex of equipment and tanks for pumping wastewater. The need to install such a station arises in cases where transporting wastewater by gravity is impossible for some reason. This is where she becomes an indispensable assistant. In this article we will look at the main design features CNS, their types, as well as features installation work and rules of service.
When choosing a pumping station, the expected volumes of wastewater, the size of the device, the degree of pollution of the wastewater and the type of pollution are taken into account. The choice is also influenced by terrain features land plot, at which the station is installed, and the depth to which the conductive pipeline is laid.
KNS device for various purposes may vary markedly, but the main parts of the design - sealed containers and pumps - are present in all models. Typically, water is drained into a reservoir by gravity, after which it is pumped out and transported to a disposal site or treatment plant. There are mini-sump pumps that connect directly to toilets. These are aesthetically designed sealed tanks of small volume, equipped with pumps with a cutting mechanism. Such KNS models are usually installed in the bathroom.
As a rule, the KNS tank is a polymer tank buried in the ground. The neck of the container is brought to the surface to facilitate routine inspection, repair and maintenance of the station. It is closed with a polymer or steel lid. Inside the tank there is a pipeline connected through pipes in the walls. The uniformity of water flow is ensured by the bumper, and the absence of flow turbulence is ensured by the water wall.
Sewage stations used for domestic purposes are equipped with 1-2 pumps. If the equipment is intended to drain wastewater from utility companies, there must be at least two pumps. Pumps are installed on pumping station for various purposes various types. For domestic stations it is better to use pumps with a cutting mechanism; for municipal ones it is not recommended, since solid waste entering the sewer can cause damage to the cutting mechanism.
The main design elements of the pump station are a sealed tank and pumps
Requirements for pumping stations, features of installation and arrangement of the sanitary zone, the required number of pipelines are regulated by SNiP 2.04.01-85 " Internal water supply and building drainage."
Regardless of the type of pump station, the operating principle of all systems is the same. Sewage is drained into the receiving part, which, thanks to the dense laying of water, does not seep into the ground, and is forced under pressure by pumps into the pressure pipeline. Next, the wastewater enters the distribution chamber and is transported through pipes to the treatment plant. To prevent waste from returning back into the pump pipeline, it is provided check valve. If the volume of wastewater increases significantly, it turns on additional pump. If the pumps cannot cope with the volume of wastewater, an alarm is activated.
The operation of the CNS is controlled automatically. The level of incoming waste is controlled using float sensors located at different levels, due to which the station operates in the following mode:
When waste pumping is completed, the wastewater level drops below the first sensor, the system turns off. The next time you turn it on, another pump is activated, which previously performed the function of an additional one. This operating system helps prevent premature wear of the mechanisms of one pump.
Additional equipment that can be equipped with a sewage pumping station:
The operation of the station is fully automated, but if necessary, it can be switched to manual control mode. This need usually arises during repairs, the need to clean a tank, or putting a new pumping station into operation.
Wastewater is pumped into the pressure pipeline, after which it enters the distribution chamber and is sent to treatment facilities
Pumping equipment is the main part of the pumping station. It pumps domestic wastewater, industrial waste, sludge, and storm water. There are the following types of sewage pumps:
A submersible sewage pump is a pressure device that is constantly submerged. Materials for the manufacture of such a pump are selected that are resistant to aggressive environments.
Most often, submersible sewage pumps are used in sewage pumping stations. They are effective and easy to use
The device is convenient and takes up relatively little space, since it is constantly submerged; there is no need to prepare a separate site for it and additional piping. Advantages of this type of pumps:
A cantilever dry installation sewage pump is a device most often used in large industrial-level pumping stations. Such pumps are not installed in modular stations. When installing them, it is necessary to prepare a separate foundation and install the pipes correctly.
Dry installation cantilever sewage pumps require separate foundation, used in large industrial-level pumping stations
It is better to entrust the commissioning of such a pump to specialists. Cantilever pumps stand open and are easily accessible, which greatly simplifies renovation work. Advantages of console pumping devices:
A self-priming dry-installation fecal pump is a unit used in municipal and industrial pumping stations for pumping heavily polluted wastewater.
Self-priming pumps are not subject to clogging and are effective in negative temperatures. The only negative is the high price
These devices are easy to maintain due to the design of the electric motor with flange mounting, and do not become clogged due to the spacious passage in the nozzle and impeller. Advantages of the device:
It should also be noted that, if necessary, such a pump can be easily dismantled.
To install the SPS, a pit is dug, the depth of which is calculated so that the tank lid protrudes 1 m above the ground surface. A 1.5 m sand cushion is installed under the bottom of the sealed container. Next, a tank is installed in the pit, pipelines are connected, after which the pit is filled with sand and compacted layer by layer . The soil density should correspond to 90% of natural density.
Then install the pumps in the tank and regulate the movement of the floats. The first level floats should be 0.15-0.3 m above the bottom of the tank. The next floats are installed 1.5 m higher than the previous ones. Next, the electrical cables are installed, the power supply is connected, and grounding is arranged. When checking the operation of the system and the performance of the pump, use clean water from the water supply or tank.
Installation and connection of power supply, grounding are carried out in accordance with SP 31-110-2003 “Design and installation of electrical installations of residential and public buildings.”
To ensure the safe operation of the sewage pumping station, pavilions can be equipped - metal, concrete, brick
Servicing of the pump station is carried out in the following order:
When repairing a pumping station, maintenance personnel must adhere to safety regulations and use protective measures. Pumps should be dismantled only after the unit has completely cooled down; it is necessary to disconnect it from the system and relieve pressure.
The construction of housing complexes is increasing at a very high speed. During the construction process, a water supply and sewerage structure is created.
Sewage and flushing pumping stations made of metal, plastic and concrete become part of this structure.
A sewer-flushing station is a device that is an automated structure. In order to ensure its correct and long-term operation, it is necessary to take into account many significant conditions.
To create a sewerage drainage system, all components must be taken into account. Including a method of temporary storage and transportation of waste waste to the point of processing or discharge. Sewage pumping stations are installed to transport sewage waste.
Sewage pumping station (SPS) is a specialized structure that is installed for the purpose of temporary storage and transportation of sewage water using external sewer pipes.
To perform this function, the CNS is provided with special equipment.
CNNs are divided according to certain characteristics, but performance parameters are mainly taken into account. In addition, you should notice differences in the design itself.
This aspect directly affects the installation method of the structure:
However, there is one significant drawback in the construction of these structures - the difficulty in installing such stations.
For home use, as a rule, modular sewage pumping stations and installations of “author’s” design are used. When producing such systems, one should take into account safety precautions and rules for installing water pumping stations for a private home.
Key advantages of modular pumping stations:
KNS device. (Click to enlarge) From the residential complex, wastewater enters the system. Air is constantly pumped into the aeration tank, which makes it possible to increase the absolute number of aerobic bacteria that are in the effluent.
Biological sludge builds up from inside the structure on a plastic load and ensures the breakdown of waste.
From the aeration tank, water flows into the settling tank, where non-degradable contaminants fall into the sediment. Pure water flows into the soil.
Note: thanks to the presence of a valve and a pump at the station, the sewage pumping station for a private house is not afraid of high standing groundwater, but continues to filter under pressure.
What is the level of importance of household treatment facilities in the KNS system? This is the main component for organizing quality cleaning. And the volume of all work depends on the productivity of the pumping station node.
The device is assembled from both polymer and metal components.
The design of the structure is determined depending on the diameter of the collector, as well as the parameters of the pipes and tank.
Installation
The system is installed on a reinforced concrete foundation. The height of the foundation must be at least 30 cm. In order to fix the body, the KNS set contains collet anchors.
Then holes are made in the foundation in accordance with the grooves on the SPS shell. After this, an anchor is driven into the hole through the groove, which is fixed inside the foundation.
In the presence of groundwater, the SPS should be loaded with concrete. The amount of concrete required for loading is calculated depending on the size of the pump station. Specialist's note: if there is a finished pit and foundation slab
Installation and use of water pumping stations in urban areas has a huge number of advantages:
Thus, by installing a sewage pumping station, it is possible to ensure the outflow of wastewater without much difficulty and harm to the environment.
Watch the video, which explains in detail the features of the design and operation of the sewage pumping station:
A sewage pumping station is used in cases where it is necessary to lift sewage from the depths and send it to the main sewer system. In this situation, the task was to forcefully pump the wastewater coming from the bathhouse into the central sewer system with the help of a pumping station. Initially, the customer wanted to supply it, but he had to be dissuaded, since TOPAS will not work if it does not contain sufficient food for bacteria. Real Sewage Pumping Stations cost from 100 thousand rubles, we offered the customer an option similar to the standard sewage pumping station and made a non-standard one. In a standard sewage pumping station, 3 or more sewage drainage pumps with cutting mechanisms are installed. We installed one drainage pump with a knife inside the tube. Collector well Alta Plast Tuba a good option for organizing a CNS with your own hands. This tube is a model Alta Plast Tuba - 2.400
How to choose the right sewage pumping station
When choosing a station for your home, remember that there is absolutely no point in buying overly powerful and, therefore, much more expensive equipment, the capabilities of which will be used by a third or even a quarter. The selected unit should be optimal and fully meet the needs of your home. For this purpose, the following parameters must be taken into account:
There are no universal formulas used when calculating equipment performance. For this reason, you should use the calculation algorithm, which, as a rule, is set out in the instructions attached to a specific CNS.
The required station capacity is calculated in the following sequence:
By correctly determining the parameters listed above, you can accurately select the optimal equipment that will fully satisfy the needs of your home.
We have already talked about the prices for sewage pumping stations a little higher. Now we want to clarify that the price is a fairly eloquent indicator:
Preference should not be given to cheap units if their operation will be daily and if there is no additional pumping equipment for evacuation and wastewater and no reserve tanks are provided.
To begin with, we deliver the materials and tools necessary for installation to the installation site. We begin to dig a foundation pit for the pumping station and...
At the same time, we install a socket inside the tube to supply power to the fecal pump. Using a percussion tool, a hole is drilled and the cable is threaded through the corrugation. The cable is mounted to the socket, and the socket is screwed onto the walls of the tube with self-tapping screws.
The outlet pipe was already in the trench and led into the central sewer system; all that remained was to connect it to the station. We are digging a pit to install a sewage pumping station.
When the pit is dug to the required depth, in our case it is 225 cm, we make a sand cushion and level the bottom of the pit. We lay guides for lowering the reinforced concrete slab.
By this time they give us a ride reinforced concrete slab, with which we will anchor our unit. Since the crane board was physically unable to enter the yard, we transported the slab manually for about 30 meters.
The reinforced concrete slab is in place, you can begin to lower the tube into the pit.
Another good thing about the tube is that it is lightweight since it consists only of plastic; we easily lowered it and installed it in place. Next, using a cable, the tube was securely fastened to the reinforced concrete slab. Now you can install the outlet pipe (PND 32) and start burying.
The tube is, of course, buried with sand so that the backfill is dense. Stacked electrical cable in the trench.
For inserting the supply sewer pipe into the station body was needed to drill a hole for the jigsaw blade and itself. A circle was cut out and wound up with a rubber seal.
All that remains is to bury...
pumped out the incoming waste.
KNS closed with a lid.
The HDPE 32 outlet pipe in the house is connected to the 50 gray sewer pipe through a transition rubber band, ensuring reliable fastening and tightness.
Overall, the customer was pleased with the work done and promised to recommend us to his friends.
