Sewage pumping plants: features of choice

In buildings where it is not possible to connect to a centralized sewage system for wastewater disposal , alternative ways of its organization should be sought. This problem is most relevant for owners of private buildings. For the disposal of waste water and their subsequent processing, special systems are used to force the pumping of domestic waste and to remove them from the building - sewage pumping units.

Purpose and Variety

This equipment is designed to remove sanitary and industrial wastewater. Depending on their location, they should be divided into internal and external sewage pumping units.

Internal

Internal or submersible equipment is mounted directly at the place of collection of liquid waste: assembly tank, gutter, settler, etc. Sewage in them occurs independently, thanks to the slope of the sewage system pipelines. As a rule, such installations are used in suburban areas.

Outdoor

These products are a combination of an assembly container and a special pump. In such a case, the installation of a sewage pumping station is carried out in multi-storey buildings, office buildings, multi-level technical and production premises, in other words, in those places where a gravity sewage system is impossible due to the difference in the height of the pipeline laying. When installed at the maximum accessible bottom point, this type of equipment can provide forcible collection of drains into the storage tank and their subsequent transfer to a place where unobstructed drift is possible.

Equipment with cutting device

Many sewage pumping plants are additionally equipped with a special grinding mechanism, which allows pumping a liquid with a high degree of contamination. By means of the action of rotating steel knife plates, the solid large components of the waste water are destroyed, thereby preventing clogging of the sewage system.

Fundamental factors

When choosing sewage pumping units, it is necessary to pay attention to the following main factors:

1. Hydrogeological conditions of the proposed installation site.
2. A way to manage pumping equipment.
3. Type of installed pumping station.
4. Depth of pipeline laying.
5. Variety of pumped liquid, minimum and maximum fractions.
6. The consistency and volume of wastewater that will flow into the unit.

Depending on the type of pumped liquid, a sewage pumping station installation may be required for:

• The drainage of water, which is formed in the treatment plants as a result of precipitation.
• Disposal of domestic sewage.
• Disposal of industrial wastewater to treatment facilities.
• Stormwater discharge.

Tips for choosing

When purchasing sewer equipment, it is necessary 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 a bath, shower, sink or waste from the toilet. For example, the sanitary sewage pumping system Grundfos is able to pump liquid without feces. For waste from the toilet, it is preferable to choose devices with a grinding mechanism.
• A distinction is made between high-capacity stations that are designed to handle structures where one-time draining of a large volume of liquid is contemplated, for example, swimming pools.

Popular manufacturers

Among consumers, the producers of Denmark, France and Germany are most popular. Let's consider the most popular models of pump installations among consumers.

Grundfos

The manufacturer of this equipment uses strong materials for manufacturing. Grundfos sewage pumping system is resistant to corrosion and can have different sizes and volumes of the tank.

Sololift series models are quite popular among consumers. This equipment is characterized by small overall dimensions and can be used for treating wastes from the toilet bowl. It can crush 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, the manufacturer produces sewage pumping units Multilift, which are designed for pumping and collection of sewage (with faeces) 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 plants from this manufacturer are characterized 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 highlight equipment series DrainLiftS. This automatic sewage pumping system is fully prepared for use, it can also be used to drain effluent from faeces. The station is characterized by various mounting options: installation on the wall, drainage of sewage from a separate structure, connection to the toilet.

The system is completed 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 productivity. They can be installed in public places, where serious loads are possible.

SFA Sanivite sewage equipment is intended for domestic use and is characterized by compact dimensions and low noise level.

Conclusion

Pumps for the sewage system are safe and practical equipment. It provides residents with a proper level of comfort, and most importantly, in terms of quality, they are not inferior to central stations.
