In buildings where it is not possible to connect to a centralized sewage system for waste water drainage, it is necessary to look for alternative ways to organize it. This problem is most relevant for owners of private buildings. For the disposal of wastewater and their subsequent processing, special systems are used for the forced pumping of household waste and their removal from the building - sewage pumping units.
Purpose and varieties
This equipment is designed to remove sanitary-hygienic and technical wastewater. Depending on their location, they should be divided into internal and external sewage pumping units.
Domestic
Indoor or submersible equipment is mounted directly at the liquid waste collection site: assembly tank, gutter, sump, etc. The effluent gets into them independently, due to the slope of the pipelines of the sewage system. As a rule, such installations are used in suburban areas.
Outdoor
These products are a combination of an assembly tank and a special pump. In this case, the installation of a sewage pumping station is carried out in multi-storey buildings, office buildings, multi-level technical and industrial premises, in other words, in those places where a self-flowing sewage system is impossible due to the difference in the height of the pipelines. When installed at the maximum accessible lower point, equipment of this type is capable of providing forced collection of drains into the storage tank and their subsequent movement to a place where unhindered gravity is possible.
Cutting Equipment
Many sewer pumping units are additionally equipped with a special grinding mechanism, which allows pumping liquid with a high degree of contamination. Due to the action of rotating steel knife plates, solid large components of the wastewater are destroyed, thereby preventing clogging of the sewer system.
Fundamental factors
When choosing sewage pumping units, it is necessary to pay attention to the following main factors:
- Hydrogeological conditions of the proposed installation site.
- A method of controlling pumping equipment.
- Type of pumping station to be installed.
- Depth of the pipeline.
- Variety of pumped fluid, minimum and maximum fractions.
- The consistency and volume of wastewater that will flow into the unit.
Depending on the type of pumped liquid, the installation of a sewage pumping station may be required for:
- Drainage of water that is formed at treatment plants as a result of precipitation.
- Disposal of domestic wastewater.
- Disposal of industrial wastewater to treatment facilities.
- Stormwater drainage.
Selection tips
When purchasing sewage equipment, you must pay attention to the following:
- Not all stations can be used for hot water.
- It is important to consider the purpose of the pump: for a bath, shower, sink or waste treatment from the toilet. For example, the Grundfos sanitary sewer pumping unit is capable of pumping liquid without feces. For waste from the toilet, it is preferable to choose devices with a grinding mechanism.
- Distinguish stations of high performance, which are designed to service structures, where it is assumed a one-time descent of a large volume of liquid, for example, pools.
Popular manufacturers
Among consumers, the most popular manufacturers are Denmark, France, Germany. Consider the most popular models of pumping units among consumers.
Grundfos
The manufacturer of this equipment uses durable materials in the manufacture. Grundfos sewage pump installation is resistant to corrosion and can have various sizes and volumes of the tank.
Quite popular among consumers are models of the Sololift series. This equipment is characterized by small overall dimensions and can be used for the treatment of waste from the toilet. It can grind toilet paper, solid fractions, and most importantly - it is easy to install. The approximate cost of such an installation is from 15 500 rubles.
Also, this manufacturer produces Multilift sewage pumping units, which are designed for pumping and collecting wastewater (with feces) located below the level of the sewage system:
- Cafes, offices, hotels, hotels.
- Plumbing systems of fitness clubs, saunas, etc.
- Semi-basement apartments, single or multi-family houses.
The cost of such a product is approximately 71,500 rubles.
Wilo
Sewer installations from this manufacturer are diverse: with one or more pumping units, with different volumes of the receiving tank, with a grinding mechanism.
Among the entire lineup, I would like to highlight the equipment of the DrainLiftS series. This automatic sewage pumping unit is fully prepared for use, it can also be used to drain effluents with feces. The station is distinguished by various mounting options: wall mounting, waste water disposal from a separate building, connection to the toilet.
The system is equipped with a tank of 45 liters, on average, its cost is about 70,800 rubles.
Sfa
The main feature of these installations is simplicity and high performance. They can be installed in public places where serious loads are possible.
The SFA Sanivite sewage equipment is designed for domestic use and is characterized by its compact size and low noise level.
Conclusion
Sewer pumps are safe and practical equipment. It provides residents with an appropriate level of comfort, and most importantly, in quality, it is not inferior to central stations.
