In buildings where it is not possible to connect to a centralized sewerage system for the removal of wastewater, 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 - sewer pumping units.
Purpose and varieties
This equipment is designed to remove sanitary and industrial wastewater. Depending on the location, they should be divided into indoor and outdoor sewage pumping units.
Domestic
Indoor or submersible equipment is installed directly at the liquid waste collection point: collection tank, gutter, sump, etc. Effluent enters them independently, due to the slope of the pipelines of the sewerage system. Typically, these settingsused in suburban areas.
Outdoor
These products are a combination of a collection 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 gravity sewer system is not possible due to a difference in the height of the pipelines. When installed at the lowest accessible point, equipment of this type is capable of forcibly collecting wastewater into a storage tank and then moving it to a place where free gravity flow is possible.
Cutter Equipment
Many sewer pumping units are additionally equipped with a special grinding mechanism that allows you to pump liquid with a high degree of contamination. Through the action of the rotating steel blades, the solid coarse constituents of the sewage are destroyed, thereby preventing clogging of the sewer system.
Underlying Factors
When choosing sewer pumping units, you need to pay attention to the following main factors:
- Hydrogeological conditions of the proposed installation site.
- Pumping equipment control method.
- Type of pumping station to be installed.
- Depth of pipelines.
- Type of pumped liquid, minimum and maximumfactions.
- Consistency and volume of wastewater that will enter the unit.
Depending on the type of liquid being pumped, a sewage pumping station may be required for:
- Drainage of water that is formed at the sewage treatment plant as a result of precipitation.
- Domestic wastewater disposal.
- Diversion of industrial wastewater to wastewater treatment plants.
- Storm water drainage.
Selection Tips
When purchasing sewer 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 a bath, shower, sink or toilet waste treatment. For example, a Grundfos sanitary sewer pumping unit is capable of pumping liquid without faeces. For toilet waste, it is preferable to choose devices with a grinding mechanism.
- Distinguish high-performance stations that are designed to service structures where a large volume of liquid is expected to be discharged at a time, 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
Manufacturer of thisequipment in the manufacture uses durable materials. The Grundfos sewage pumping unit is corrosion resistant and available in a variety of tank sizes and volumes.
Sololift series models are quite in demand among consumers. 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.
This manufacturer also produces Multilift sewer pumping units, which are designed to pump and collect wastewater (with feces) located below the level of the sewer system:
- Cafes, offices, hotels, inns.
- Plumbing systems for fitness clubs, saunas, etc.
- Semi-basement apartments, single or multi-family homes.
The cost of such a product is approximately 71,500 rubles.
Wilo
Sewage installations from this manufacturer are distinguished by a wide variety: with one or more pumping units, with different volumes of the receiving tank, with a grinding mechanism.
Among the entire model range, 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 for draining sewage with faeces. The station is distinguished by various mounting options: wall mounting, wastewater disposalfrom a separate building, connected 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 plants 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
Sewage system pumps are safe and practical equipment. It provides residents with the proper level of comfort, and most importantly, the quality is in no way inferior to the central stations.
