Drainage sewage treatment plants

Domestic drainage treatment plants are an ideal example of a domestic treatment plant in a place where there are favorable ground conditions. The condition for installation is that the soil is well permeable and the groundwater level is sufficiently low. The operation of the treatment plant is based on two processes: anaerobic, which is in the settling tank, and aerobic, which is in the leach drains. That is why the previously mentioned conditions are very important. It is also worth paying attention to the location of the treatment plant on the plot. It is necessary to remember that the settling tank and drain should be adequately distanced from the building and the border of the plot, etc. These distances are conditioned by law. For more information, please see our guides. We invite you to read the guides:

Structure and working of drainage treatment plants

Drainage treatment plants consist of 2 basic elements: 

  • The septic tank, which is the basic equipment found in all technological systems in which the first stage of treatment (i.e. the so-called anaerobic pretreatment) is implemented. Pre-treatment of wastewater takes place in it. Pollutants heavier than water sink to the bottom (sedimentation) and decompose in the process of anaerobic digestion. Lighter ones float to the surface and form a skin (flotation). As a result of the processes taking place, mainly floating impurities and suspended solids and organic compounds are removed from the wastewater.
  • Drainage system - a system of underground perforated drainage pipes (drains) that introduce wastewater pretreated in a septic tank into the ground. The wastewater, flowing through successive filter layers of gravel and sand (laid under the drains), is decomposed by biological oxidation processes, with the help of microorganisms.
For more information, please see our guide section. We invite you to read our guide - Technical conditions for the foundation of wastewater treatment plants. 

Aquatechnika is the ideal place to buy a drainage treatment plant. We guarantee delivery all over Poland - Warszawa, Kraków, Wrocław, Poznań, Szczecin, Łódź, Katowice,others and foreign deliveries. Before making a choice, we invite you to check attractive offers and contact our advisors.  We offer the lowest prices and the possibility to negotiate.

Do you need a permit to build a treatment plant?

Domestic sewage treatment plants with a capacity of up to 7.5 m3 per day do not require a building permit, but a simple notification (Article 29(1)(3) and Article 30(1)(1) of the Building Law). The presence of a municipal sewage system precludes the possibility of placing a treatment plant. In addition, it is forbidden to build it in periodically flooded areas. For more information also on the water permit and the notification procedure, see the guide.

Which treatment plant will be suitable for allotment gardens?

When selecting the type of sewage treatment plant for a particular plot of land, several factors need to be taken into account. These include the size of the plot of land, groundwater level, and soil permeability. A drainage treatment plant works well when there is a relatively large area of land and groundwater conditions are favourable (low groundwater level and good soil permeability). Biological wastewater treatment plants are a more modern solution, complying with European standards (they can be used in agglomerations). However, their disadvantage is that they require a power supply. For more information on the selection of treatment plants, see the guide.

How often should the settling tank be emptied?

The frequency of emptying the settling tank depends on the number of people using the installation and the size of the settling tank. It is generally agreed that the sludge should be emptied annually. It is best to have the sludge emptied by a specialist company, as it needs to be recycled. Sludge is a by-product of the fermentation process that is carried out by bacteria. It is also important to remember to periodically add a portion of bacteria to the sewage treatment plant. Biopreparations support the operation of the sewage treatment plant and remove unpleasant odours.

Should the drain be covered with gravel?

A standard drain consists of a system of several perforated plastic pipes connected in parallel. Their purpose is to distribute the treated wastewater evenly to the filter layer, which should just be made of gravel or small crushed stone. An alternative to such a solution are infiltration boxes, which do not require a gravel layer. The number of boxes depends on the number of people using the system and the permeability of the soil. More information and selection instructions can be found in the guide.

What is the difference between tunnels and drainage pipes?

Tunnels take up less space than drainage pipes and can be used in soils with poor permeability. In addition, the fact that drainage pipes are subject to clogging must be taken into account. Tunnels are considered to be a more efficient and less fail-safe solution.
0

What distances should the pipes/tunnels be placed?

Individual drainage pipes should be spaced at least 1.5 m apart. They should be installed with a slope of 1 to 3 per mil. The maximum length of one drainage pipe should not exceed 25 metres. For more information see the guide.
0

Can plants be placed over the drainage?

Plants with a developed root system must not be planted in this area as it could damage the installation. The drainage distance from trees and shrubs is assumed to be approximately 3 m. This distance is conventional and should be treated with common sense. For more information see the guide.
1

How many chamber settling tanks should I choose?

For larger tank capacities, we recommend two- or even three-chamber solutions. Multi-chamber settling tanks improve the efficiency of the treatment process, resulting in better treated wastewater. A multi-chamber settling tank in a domestic wastewater treatment plant better separates solids and fatty substances.
