In areas without municipal sewage, i.e., a unified sewage system for wastewater disposal, septic tanks must be constructed.
You can learn more about septic tanks on our specialized website for SEPTIC TANKS. Septic tanks are made for hygiene reasons, preventing the spread of infection on the terrain and the spread of unpleasant odors.
They are most commonly built or proper septic tanks are installed.
Čabar plast septic tanks offer you an ideal and quick solution for solving all problems with wastewater from your household, weekend house, school, kindergarten, business or residential space.
Our plastic septic tanks have many advantages compared to traditional built or concrete septic tanks.
Most commonly made as horizontal plastic tanks or cisterns for wastewater and are placed in the ground by burying. The advantage of these tanks is that they do not leak water at all. Čabar plast septic tanks are quickly installed and functional within one day. All standard and any other connections can be fitted to them.
Their greatest advantage is complete resistance to wear; the material from which Čabar plast tanks and septic tanks are made is high-density polyethylene (HDPE), which has high tensile strength as well as pressure resistance. . Čabar plast septic tanks are resistant to high and extremely low temperatures from -30°C to +80°C.
The first plastic septic tank, as we know it today, is not clearly defined by the date of creation, as the development of plastic septic tanks occurred gradually with advancements in the production and processing of plastics. Materials such as high-density polyethylene (HDPE) and polypropylene (PP), which are common today for making plastic septic tanks, only became widely available during the second half of the 20th century.
The first patent for a septic tank was issued in 1881 to the Frenchman Jean-Louis Mouras. However, this was not a plastic septic tank, but an early form of septic system that used natural materials since 1860. The development and commercialization of plastic septic tanks began much later, only in the second half of the 20th century, when plastic manufacturing technologies improved and the advantages of using plastics for this application were recognized, including corrosion resistance, ease of installation, and long lifespan.
Therefore, although there is no exact date when the first plastic septic tank was made, it can be assumed that it occurred several decades after the introduction of modern plastic materials into mass production.
Čabar plast septic tanks are also resistant to the effects of groundwater. Čabar plast septic tanks proved themselves best during the May 2014 floods because they did not overflow and spill, which means they do not leak water either from the inside or outside. Therefore, they are ideal in preserving human living space and protecting the environment.
SEPTIC TANKS DIVISION AND CAPACITY
Septic tanks are made as two-chamber and three-chamber septic tanks. These are flow-through septic tanks. Their capacity for a family of four to five members is about 6000 liters.
Non-flow-through septic tanks, which can be both horizontal and vertical. Non-flow-through septic tanks are overflow and from them partially purified wastewater goes to places where its presence will not endanger drinking water sources. It is drained by drains into drainage channels and similar.
The price of a septic tank mainly depends on its capacity, i.e., size. Larger septic tanks, which can accommodate a larger amount of wastewater, are usually more expensive due to higher material costs and a more complex installation process.
Flow-through and non-flow-through septic tanks are two different types of wastewater treatment and disposal systems used in areas without access to a centralized sewage system. They differ in the way they manage and treat wastewater:
Flow-through septic tanks are designed to allow the passage of purified water through the system and its discharge into the environment, usually into a drainage field or infiltration trench. This type of septic tank has multiple chambers – usually two or three. In the first chamber, solid materials settle and initial decomposition occurs, while further decomposition and water purification take place in the following chambers. The purified water eventually leaves the septic tank and slowly filters through the soil in the drainage field, where it is further purified before returning to the groundwater.
Non-flow-through septic tanks, also known as closed or holding tanks, are designed to retain all wastewater within the tank, without discharging it into the environment. This type of septic tank does not have an outlet for purified water; instead, all wastewater is collected inside the tank until it is pumped out and taken to another location for disposal or further purification. Non-flow-through septic tanks are more commonly used when soil conditions do not allow efficient filtration or when the risk of groundwater contamination is high.
The decision between flow-through and non-flow-through septic tanks depends on specific site conditions, such as soil type, groundwater level, spatial constraints, and local regulations. Flow-through septic tanks offer the advantage of additional purification through the soil but require more space and favorable soil conditions, while non-flow-through septic tanks provide a solution for locations where flow-through systems are not feasible.

If you are unsure which size of septic tank to choose, approximately estimate that one household member uses about 150 liters of water per day. Which comes to about 4.5 cubic meters per household on a monthly basis. According to some standards, the minimum volume of a septic tank is 4 cubic meters, but if you choose a larger one, you will not regret it, just to know that in some countries the minimum volume of a septic tank is over 10 cubic meters.
A single-chamber septic tank is the basic type of septic system consisting of one large chamber where wastewater is collected and treated. In this chamber, solid materials separate and settle at the bottom, while fats and oils float on the surface. Microorganisms within the tank break down these materials, but due to the simple construction, the purification process is not as efficient as in septic tanks with multiple chambers. Single-chamber tanks are often suitable for smaller facilities or households with a low level of wastewater.
A dual-chamber septic tank consists of two separate chambers connected by a passage or pipe. The purification process begins in the first chamber, where solid materials settle, and then the purified water moves to the second chamber for further treatment. This additional chamber allows for better separation of solid materials from the water and more efficient purification, resulting in cleaner water being discharged into the environment.
Dual-chamber septic tanks are suitable for larger households or small communities where there is a greater amount of wastewater.
A three-chamber septic tank is a more advanced system that includes three interconnected chambers for wastewater treatment. Similar to two-chamber tanks, each chamber has a specific role in the purification process. The first chamber is for the settling of solid materials, the second chamber for further decomposition and purification, and the third chamber serves as the final purification stage before the water is discharged into the environment. Three-chamber septic tanks provide a high level of purification and are often used in larger facilities, schools, restaurants, or small settlements where efficient disposal of a larger volume of wastewater is required.
A four-chamber or multi-chamber septic tank represents a complex wastewater treatment system that includes four or more chambers. Each chamber plays a role in the purification process, allowing for gradual and thorough purification of wastewater. These systems are often equipped with additional features such as filters, aerators, or systems for introducing additional microorganisms, further improving purification efficiency. Multi-chamber septic tanks are ideal for large residential complexes, hotels, factories, and other facilities with high requirements for treating and purifying large volumes of wastewater.
