      The difference between a septic tank and an autonomous sewage system

      Septic tanks and an autonomous sewage system refer to local treatment facilities that must be installed in a country house for human comfort. The sewage system from septic tanks and the autonomous sewage system perform wastewater treatment, the main difference between them is the method of treatment.
      The first thing that distinguishes a septic tank from an autonomous sewage system is the principle of processing. Aerobic bacteria better decompose biological waste, the result of their vital activity is mineralized sludge. It is used as a fertilizer. Sludge formation occurs slowly, you can remove the excess yourself using a submersible pump or its equivalent.
      Features of the arrangement of an autonomous sewage system:

      1. Connection to the mains is mandatory. For the vital activity of aerobic bacteria, water must be enriched with oxygen, for which one or more compressors are provided in the treatment plant.
      2. No additional filtration measures are needed, the liquid is purified up to 99%. But to use it as water, additional purification is required.
      3. Relative disadvantage – downtime should not exceed 7-10 days, otherwise the number of aerobic bacteria will begin to decrease rapidly. But even in this case, you can replenish their quantity with the help of special additives. The time to reach a full-fledged processing cycle will be 3-5 days.

      Types of Septic Systems

      Septic system design and size can vary widely, from within your neighborhood to across the country, due to a combination of factors. These factors include household size, soil type, site slope, lot size, proximity to sensitive water bodies, weather conditions, or even local regulations. Below are ten of the most common types of septic systems used. The list is not all-inclusive; there are many other types of septic systems.
      The most common septic systems from septic tanks:

      • Septic Tank
      • Conventional System
      • Chamber System
      • Drip Distribution System
      • Aerobic Treatment Unit
      • Mound Systems
      • Recirculating Sand Filter System
      • Evapotranspiration System
      • Constructed Wetland System
      • Cluster / Community System

        The price of an autonomous sewage system and septic tanks is formed based on the operational functionality, the quality of the installation, the volume of the tank, the popularity of the manufacturer and other working and technical qualities.
        The cost of an autonomous sewage system depends on:

        • The complexity of the design of a particular system. Standard tanks, which do not use airlifts and aerators, cost significantly less (several times) than septic tanks with such innovative solutions implemented.
        • The volumes of the installed containers. Of course, large-volume structures entail significant material consumption. For this reason, the cost in general grows naturally.
        • Autonomous system performance. This factor is similar to the previous one, because the cost is also fully dependent on the cost of labor resources and the amount of materials used. In addition, high-performance designs quite often require the installation of more powerful equipment: in a situation with septic tanks, powerful compressors.
        • Manufacturer brand awareness. Now there are a lot of companies and brands that make septic tanks, the more famous the brand, the more expensive their products will be.
        • The cost of a septic tank strongly depends on the reliability of the materials used to create it, the sales season (in summer and spring, the price of septic tanks will be higher than in winter or autumn), the total cost of a turnkey installation and other criteria.

      What is better septic tank or autonomous sewage system?

      When planning the construction of a private house, even at the design stage, you need to solve the dilemma of what to prefer a septic tank or an autonomous sewage system. Which is better in terms of operation, performance and maintenance. Make the right choice mono only when there is a concept of the difference between these two treatment plants.

      Septic tank

      The concept of a septic tank should be understood as a system consisting of overflow tanks (wells) into which sewage drains are discharged. They settle there, the organic sediment is fermented biologically without oxygen supply.

      Sewerage septic tank for home

      The percentage of the quality of wastewater treatment in a septic tank is approximately 85%. There is a difference between septic tanks and autonomous sewers in this regard. In the first case, the percentage of cleaning is up to 85%, in the second – about 60%.

      To increase the efficiency and quality, the septic tank is designed and installed with an additional post-treatment unit. They include:

      • filter well;
      • irrigation dome;
      • filtering field.

      The purpose of septic tanks is to collect wastewater for further treatment and disposal into the soil. There are different cleaning technologies. The quality and performance depend on the modification of the treatment system.

      What is better a septic tank or an ordinary autonomous sewage system is an important issue in the improvement of private houses. You can understand it if you understand the difference between these constructions.

      Disadvantages of a conventional septic tank

      These treatment systems also have negative points:

      1. The quality of wastewater treatment cannot be called high. The discharged water should be further purified before being drained into the ground.
      2. Duration of treatment processes. In order for the drains to settle, you need to wait about 3 days.
      3. Relatively simple installation is possible only in areas with the most ideal conditions. If this is not the case, additional mounting structures have to be erected. Use of special equipment during installation.
      4. From time to time you have to use the services of sewers.

      Autonomous sewerage

      Autonomous sewerage and septic tank are different. A good self-contained sewage treatment system is a system in which sewage is cleaned from start to finish. The discharged water does not need to be further purified, it is sent directly into the reservoir or used for technical purposes. This is achieved thanks to aerobic treatment technology.

      Autonomous sewerage at home

      The difference between a good septic tank and an autonomous sewage system is that in the first version, an anaerobic (without oxygen access) purification technique is used, in the second, aerobic (with oxygen access). For full air access to the tank, the station is equipped with:

      • aerator;
      • compressor;
      • sensor of control, supply and control of work.

      Operating principle

      In a plant with deep biological treatment, the same method is used – waste settling. Only in this version they undergo biological processes. Due to the access of oxygen, the processes of decomposition of organic matter are faster. What affects the quality of treated water. The efficiency of an autonomous sewage system is considered high, the percentage of cleaning quality is 97-99%.

      Installed autonomous sewage

      The septic installation differs from the autonomous sewage system in that in the first option you need to build a filtration platform, in the second option it is not.

      Benefits of an autonomous system

      Let’s analyze the positive properties of autonomous sewers for country houses:

      • compact dimensions, make it possible to install the structure even in areas with a high density of buildings;
      • wastelessness – settled and purified water can be used for technical purposes, sediment – as organic fertilizer;
      • high efficiency makes it possible to install very large tanks, in which you can clean the sewage of the entire street;
      • installation of a biological treatment plant can be carried out on any type of soil or terrain;
      • complete absence of fumes, which means unpleasant odors.

      7 differences between a septic tank and an autonomous sewage system

      1. The technology of wastewater treatment in the first version without oxygen access, in the second with its artificial supply to the treatment well.
      2. With the installation, the first unit is installed in ideal conditions, the second anywhere, even in conditions of increased building density.
      3. A modification of a septic tank can be bought ready-made or made with your own hands, the second is produced at the factory, it is impossible to make it with your own hands.
      4. Efficiency – septic tanks need periodic pumping out of wastewater, autonomous sewage system guarantees waste-free production.
      5. Electricity. The septic tank works autonomously, the autonomous system requires an electrical connection.
      6. The quality of sewage treatment in the septic tank is 85%, the autonomous unit can produce 99% of the quality of treatment.
      7. Tightness. In the first option, unpleasant odors may emanate due to loose sealing, in the second – a complete absence of fumes.
