According to Polish law, every property owner is obliged to connect the sewage system to the premises. But what if you are building a year-round or holiday home and setting up a sewage system is technically impossible? Or simply such an investment does not make sense from an economic perspective? The solution is a home biological sewage treatment plant. An alternative for both traditional sewage and septic tanks. In the article, we suggest what models are available on the market, and what advantages they have.

Biological sewage treatment plant – how does it work?

The task of a biological sewage treatment plant is to return clean water to the environment. Such water is suitable for discharge into watercourses or absorption wells. It can also be successfully used for watering the garden. Sewage treatment takes place as a result of various biological processes. We distinguish two types of them:

  • aerobic,
  • anaerobic.

Aerobic treatment involves aerobes – bacteria that break down pollutants with the participation of oxygen. This process is used for sewage with a lower degree of contamination with organic compounds.

Anaerobic treatment, on the other hand, uses the work of anaerobes – microorganisms that work in anaerobic conditions. This process works well for sewage with a higher degree of contamination with organic compounds.

For maximum efficiency, anaerobic treatment is used together with aerobic treatment.

Home sewage treatment plant – how to choose?

It is worth paying attention to:

  • the capacity of the home sewage treatment plant,
  • for how many users the sewage treatment plant is designed,
  • whether the home sewage treatment plant has necessary certificates,
  • what is its energy consumption and operating costs.

How much does a home sewage treatment plant cost? Everything depends on its construction and the technology used. Prices for ecological sewage treatment plants (for 4-5 people) start from 6-8 thousand (version with a drainage system) to even 18 thousand (home sewage treatment plant with active sludge).


Models of biological sewage treatment plants

Biological sewage treatment plant HC1 2000L effectively treats domestic and economic sewage, even if it arrives in uneven amounts or there is a periodic lack of water. The reduction of pollutants is very effective. The treatment plant consists of a 3-chamber system (preliminary settler, biological reducer, secondary settler).

The device can be installed without having professional knowledge. The treatment plant also does not require user supervision.

It will work perfectly in holiday homes or small single-family houses.

Practical advantages of the home sewage treatment plant 2000L:

  • takes up little space,
  • no need to clean the bed, 
  • long life of elements,

The intuitive biological sewage treatment plant HC2 3400L works perfectly in larger households. The station can even be expanded. The device flawlessly handles domestic and economic sewage, which arrives in uneven amounts. It also has no problem with a periodic lack of water. The home biological sewage treatment plant is built from a 3-chamber system (preliminary settler, biological reducer, secondary settler). The device shows high productivity with minimal spatial and energy requirements.

Practical advantages of the home sewage treatment plant 3400L:

  • high durability of elements,
  • high resistance to changing weather conditions,
  • easy supervision system,

Actibloc is a series of technologically advanced, biological sewage treatment plants. They are used by owners of single-family houses, campsites, holiday homes, hotels, small companies.

The device shows high efficiency of sewage treatment regardless of their quantity and quality. The operation is not disturbed by interruptions in water supply. The stable and effective operation of the treatment plant results from the combination of 2 tanks – one serves as a settler equalizing the unevenness of discharges, and the other is the so-called SBR, i.e. Sequential Biological Reactor with active sludge. The cost of purchasing a home biological station Actibloc pays off on average after 2-3 years of use.

Practical advantages of Actibloc home sewage treatment plants:

  • the device is covered by a 10-year warranty,
  • uncomplicated installation (possible in almost any water-soil conditions),

Advantages of home biological sewage treatment plants

Biological treatment plants (regardless of technological advancement) are chosen due to several strong pluses.

1. Convenience of using a sewage treatment plant

The settler in a biological treatment plant is emptied once a year or even every 2 years, if we take care not to throw bio waste, such as food leftovers, into the sink. For comparison, a septic tank needs to be emptied every 2-3 weeks.

2. Biological treatment plant - aesthetics

Sewage treatment plants are not a source of unpleasant odors and do not threaten to break out of sewage – unlike a traditional septic tank.

3. Biological treatment plants - economy

The purchase of a biological treatment plant pays off on average after 2-3 years. The only additional cost associated with daily use of such a treatment plant is the replacement of the blower every 5 years.

4. Ecological treatment plant - in harmony with nature

Biological treatment plants guarantee high reduction of pollutants, and at the same time allow to control the quality of treated sewage. Clean water is safe for the environment and can be reused, e.g. for watering the garden.

5. Funding

Local authorities offer many possibilities for funding the installation of a biological treatment plant.

6. Universality of sewage treatment plants

Biological treatment plants – even very technologically advanced – take up little space. The area needed for such a treatment plant is roughly the area of 2-3 standard parking spaces. We can place a biological treatment plant practically anywhere, e.g. under paving stones or in a marshy area.

7. Easy self-installation

Each biological treatment plant, available in the offer of Eco24 store, comes with a full installation and operation manual. We do not have to specially hire a separate team. The installation can be entrusted to people who work on the construction site.  

Home sewage treatment plants – what to remember?

Is this your first approach to installing a home sewage treatment plant? It's worth remembering:

  • contact the Municipal Office – sometimes private, pro-ecological investments are co-financed,
  • if you have doubts, seek advice from a company specialized in the installation of home sewage treatment plants – it will help in choosing the right technology and determining the place for installation,
  • make sure you do not have to report the investment in the county and wait for the consent of the appropriate body.
