In buildings where it is not possibleconnection to a centralized sewer system for wastewater disposal, it is necessary to look for alternative ways to organize it. This problem is most relevant for owners of private buildings. For disposal of sewage and their subsequent processing, special systems are used for forced pumping of household waste and their removal from the building - sewage pumping installations.
Purpose and Varieties
This equipment is intended to be removed.sanitary and technical waste water. Depending on the location, they should be divided into internal and external sewage pumping installations.
Internal
Internal or submersible equipment mounteddirectly at the liquid waste collection site: an assembly tank, a gutter, a settling tank, etc. Falls into them occurs independently, due to the slope of the sewage system pipelines. As a rule, such installations are used in suburban areas.
Outdoor
These products are a combination ofassembly 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 gravity-flow sewage systems are impossible due to the difference in pipeline installation height. When installed in the maximum accessible lower point, this type of equipment is capable of ensuring the forced collection into the accumulative tank of drains and their subsequent transfer to a place where unobstructed gravity can occur.
Equipment with a cutting mechanism
Many sewer pumping installationsadditionally equipped with a special grinding mechanism that allows you to pump liquid with a high degree of contamination. Through the action of rotating steel knife plates, solid major components of wastewater are destroyed, thereby preventing clogging of the sewer system.
Underlying factors
Choosing sewer pumping installations, it is necessary to pay attention to the following main factors:
- Hydrogeological conditions of the proposed installation site.
- The method of controlling pumping equipment.
- Type of pump station to be installed.
- Depth of pipelines.
- Variety of pumped liquid, minimum and maximum fractions.
- 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, which is formed in sewage treatment plants as a result of precipitation.
- Disposal of domestic wastewater.
- Disposal of industrial wastewater to sewage treatment plants.
- Stormwater drainage.
Tips for choosing
When purchasing sewage equipment, you need to 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 bath, shower, sink or waste treatment from the toilet bowl. For example, the sanitary sewage pumping unit Grundfos is capable of pumping liquid without faeces. For waste from the toilet, it is preferable to choose a device with a grinding mechanism.
- Distinguish stations of high performance, which are designed to service structures, where it is assumed one-time descent of a large volume of fluid, for example, pools.
Popular manufacturers
Among consumers, manufacturers of Denmark, France, and Germany are the most popular. Consider the most popular among consumers models of pumping units.
Grundfos
The manufacturer of this equipment in the manufacture uses durable materials. The Grundfos sewage pumping unit is corrosion resistant and may have different tank sizes and volumes.
Pretty in demand among consumers of the model.Sololift series. This equipment is characterized by small overall dimensions and can be used to process waste from the toilet bowl. It can shred toilet paper, solid fractions, and most importantly, it is easy to install. The approximate cost of such an installation of 15 500 rubles.
Also, this manufacturer producesMultilift sewage pumping units, which are designed for pumping and collecting wastewater (with faeces) located below the level of the sewage system:
- Cafe, offices, hotels, hotels.
- Plumbing systems of fitness clubs, saunas, etc.
- Basement apartments, single or multi-family houses.
The cost of such a product is about 71,500 rubles.
Wilo
Sewerage installations from this manufacturer are distinguished by a wide variety: with one or several pumping units, with a different volume of the receiving tank, with a grinding mechanism.
Among the entire model range I want to highlightDrainLiftS series equipment. This automatic sewage pumping unit is fully prepared for use, it can also be used for drainage of faeces. The station has different installation options: installation on the wall, removal of sewage 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 are allowed to be installed in public places where serious loads are possible.
SFA Sanivite sewage equipment is designed for domestic use and is characterized by its compact size and low noise level.
Conclusion
Pumps for sewage systems are safe and practical equipment. It provides residents with an adequate level of comfort, and most importantly, the quality is in no way inferior to the central stations.
