The Fast septic tank is an excellent example of a household wastewater treatment system produced by the American company of the same name. After all, Fast modules can clean wastewater per day. Moreover, the dimensions of even a fairly productive model do not exceed 100 centimeters along any edge (height, width or length).
That is, setting up a cleaning system will not take much time and will not require serious labor costs. Moreover, such modules can be integrated into existing settling tanks.
Septic tank "Fast"
That is why the modified Fast septic tank, which uses an aerobic cleaning scheme that guarantees a high degree of clarification of even the dirtiest wastewater (up to 98 percent), is popular among owners of country houses, cottages, mini-hotels and cafes. And in this article we will look at the model range of the American brand Fast, simultaneously studying the process of arranging cleaning systems from this manufacturer.
Advantages and disadvantages ↑
Despite the good reviews from the owners of Fast septic tanks, advertising and excellent sales figures for treatment plants of this sewage equipment, the products of the American brand also have a number of advantages and disadvantages.
Which of them is greater, judge for yourself. The advantages often include the following points and parameters of septic tanks of the Fast series:
- guaranteed service life – 50 years;
- according to the principle of operation and ensuring the comfort of autonomous sewer networks, Fast septic tanks are close to city centralized sewer networks;
- does not require maintenance to pump out accumulated sludge;
- when using a septic tank for its intended purpose, following all recommendations and rules, it is almost impossible to disable the equipment;
- if particles prohibited by the manufacturer enter the septic tank, the operation of the treatment equipment is quickly restored and does not require an emergency shutdown of the entire sewer system to clean the septic tank;
- it is allowed to install a Fast septic tank at a distance of 2 meters from the house or more, which is a significant factor for those houses whose surrounding area is very small;
- the treatment plant can be installed at any depth and adjusted or adapted to any soil conditions in your area;
- the system allows you to pump out accumulated sediment no more than once every 4 or more years;
- a long downtime of the treatment plant without power supply is possible, and the system will not deteriorate at all, so it can be used quite easily both year-round and seasonally;
- The Fast deep cleaning station has pipes for gravity discharge of wastewater during an emergency power outage and a number of other special devices. Therefore, when the power supply is turned off, you can use the autonomous sewer system for a few more days and the septic tank will not overflow;
- processing of any types of domestic wastewater;
- in the design of the Fast septic tank there is no need to change, clean or wash any parts;
- the operation of the septic tank does not provoke the appearance of unpleasant odors;
- there is no need to regularly seed activated sludge or add bacteria;
- most models of Fast systems have a sufficient volume of tanks to accept the maximum number of salvo discharges to serve families with a certain number of permanent residents;
- the septic tank is perfectly buried in any type of soil, does not require above-ground buildings that would protect it from rain, as happens during installation in the case of some local treatment plants;
- There is no need to install additional filtration fields, wells or tanks for post-treatment;
- are completely immersed underground, except for the ventilation pipe, and therefore do not spoil the landscape view;
- almost completely adapted to all conditions of any location, from Alaska to Africa or the Middle East;
- high degree of wastewater purification up to 98%.
With such advantages, it immediately becomes clear to most buyers that we are faced with highly professional sewerage equipment for wastewater treatment.
The disadvantages of the Fast septic tank include only a couple of points with which buyers may be dissatisfied or are not satisfied with them for some reason.
These disadvantages could be the following:
- excessively high price;
- energy dependence.
Thus, it becomes clear that the Fast septic tank has more advantages than disadvantages. In addition, these advantages relate more to operational and technological qualities, which is important for the effective operation of a local treatment plant.
What kind of septic tank is this?
You need to understand that the Fast model is not an autonomous septic tank, but only part of a local treatment plant in which the main cycle of aerobic cleaning of sewer drains takes place.
Fast is a container without a bottom, made of plastic. The inside of the unit is filled with honeycomb filler, and an airlift is installed in the middle. The unit is supplied with compressed air ducts, a cover and other parts.
Description of settings
Sewage in the Fast septic tank is processed using bacteria. Purification cycles use aerobe bacteria, which require oxygen to exist and feed.
Advice! All modern septic tanks use aerobic waste disposal technology, since only this treatment method allows achieving an acceptable level of impurity extraction, allowing water to be discharged without additional treatment.
When using Fast septic tanks, there is no need to add additional biomaterials to the installation. The bacteria are grown directly on the honeycomb. With anaerobic cleaning technology, no unpleasant-smelling gases are released, therefore, when operating Fast units, there is no fear of the spread of a bad odor throughout the area.
The equipment used in these installations has the unique ability to self-clean. Therefore, it is enough to carry out maintenance and cleaning of the septic tank once every 4 years.
A useful quality of the installations is the possibility of their seasonal use. If necessary, the septic tank can be turned off without carrying out labor-intensive conservation operations. You don’t even need to empty the containers of residual wastewater and water; it will be enough to simply turn off the electrical equipment.
Advice! In the model range of Fast brand septic tanks there is an option that is used to work in conjunction with other types of installations. This option is a real boon for home owners in which the old sewer system does not work efficiently. When purchasing such a model, it is connected to the previous system, which significantly improves the quality of its operation.
Operating principle
The process of processing plums is carried out in several stages:
- The first chamber is septic; it mechanically separates the incoming medium into fractions by weight. Inclusions whose weight is higher than that of water settle to the bottom. Light impurities collect at the top in the form of foam, but gradually they split and partially settle to the bottom;
- Partially purified water is supplied to chambers in which an aerator is installed, where air is supplied using a compressor. When passing through the honeycomb filler, the wastewater is cleared of most organic impurities;
- The recycled liquid is then discharged into a ditch or storage well.
Modifications and their technical characteristics ↑
All cleaning products, such as the American Fast septic tank, do not have a large range of models, but they fully meet certain consumer requirements.
Systems of unique technological developments for the purification of household wastewater differ from each other in their parameters, size, power and performance.
All modifications are suitable for any type of country property and will fully provide highly effective sewage treatment.

Septic tanks of the Fast Retro series are very good for use on land plots of small dachas and houses where no more than 8 people live permanently.

Their designs make it possible to serve small salvo discharges that have exceptional volumes, and therefore these models should be selected according to the amount of water used per day.
One of the unique abilities of the Fast septic tank device is its restoration of the permeability properties of the soil, and therefore these septic tanks are very profitable to install in old autonomous sewer systems.
At the same time, the treatment plant can be installed in two or three houses, where daily water consumption reaches 300 liters per day per person.
Fast Micro septic tanks can already serve a larger number of people - up to 63. Accordingly, the total volumes of consumption and use of water will be much higher than the volumes of consumption and use in country houses, cottages or country houses.

Treatment systems designed to process large volumes of sewage waste serve supermarkets, cafes, restaurants, holiday homes, sanatoriums or boarding houses, as well as car washes and other enterprises.
And some models are designed specifically for cleaning reservoirs, lakes and even servicing sewers equipped on river and sea yachts or any other vessels.
That is why such a septic tank is the best option for use in an individual sewage system.
What work needs to be done to calculate a septic tank for a private home, see the article: calculation of a septic tank. Reviews from buyers of the Aspen septic tank are here.
How does it work?
So, the Fast septic tank is an energy-dependent biofilter. Inside the container there is a honeycomb filler, in the center there is an airlift. Colonies of microorganisms live on the surface of the honeycomb filler; air is supplied to the installation using a compressor. Thus, the installation carries out aerobic biological treatment.
The Fast module is installed inside the septic tank. The sump can be made of plastic or reinforced concrete. You can install the module in an already used monolithic reinforced concrete septic tank or in a septic tank made of concrete rings.
Cleaning process
Thus, wastewater goes through several stages of purification. First they enter the septic chamber, where they undergo a settling process. Then, the wastewater, freed from most of the undissolved impurities, enters the Fast module using a pump, where it undergoes biological treatment under conditions of additional oxygen supply.
The presence of a honeycomb filler provides a large biological filter area, so the liquid undergoes complete purification. After passing through the Fast module, the liquid can be sent directly to the discharge. That is, the installation of this device allows you to do without the construction of filtration fields.
Operating principle ↑
In order to understand the principle of operation of the Fast septic tank, it is necessary to study its structure. The treatment plant is designed in such a way that all work inside the septic tank for processing sewage waste occurs as quickly as possible, with odorless gases being removed outside and an air flow entering the aeration tank system built inside.
The septic tank consists of a main receiving tank, a secondary settling tank and an aeration tank, a pump and a special module built into the chambers, where one of the stages of wastewater processing takes place.
In addition to these devices, there is also a fan, with the help of which air is pumped into the aeration tank.
Photo: operating principle of the Fast septic tank
The wastewater treatment process follows the same scenario as the treatment process of most deep biological treatment stations.
Initially, “gray” sewage water enters the receiving chamber, where it is immediately exposed to active biological substances - aerobic bacteria, which, unlike traditional septic tanks, are located on the surface of the active medium.
Using a fan and compressor, air is supplied to the chamber, which enriches wastewater and active biomass.
When exposed to oxygen, biomass begins active life by “eating” and processing sewer liquid along with soft organic particles, inclusions such as feces or food debris.
The work includes not only a compressor and a fan, but also an airlift and a pump, which are involved in pumping and moving wastewater.
The wastewater is also processed in a special cellular structure called a module, where, under constant mixing of air, active bacteria and wastewater, the wastewater is converted into sludge and water.
In the next chamber, water with impurities of silt formations settles, becoming naturally clarified due to sediment settling to the bottom.
It should also be said that in the second module or chamber, half (or more) purified wastewater is also transformed under the influence of anaerobic microorganisms, which continue to work on decomposing particles in the sewer liquid to the ground.
These bacteria exist and live without oxygen, and therefore there is no aeration tank in the second module.
Important! It is also very important to understand what exactly the principle of self-healing of the system is.
If chlorine-containing substances or any pipe cleaner such as Tiret, which itself is an aggressive chemical, enters through the sewer pipeline, the colonies of bacteria formed in the cellular structures may die.
However, those microorganisms that were deposited on the surface of the drains, walls and other surfaces of the internal devices of the septic tank die.
And those bacteria that are still inside the cells remain alive, continuing their reproduction. It is this aspect that is key in the process of self-healing of the system.
Important! The most important condition for the operating principle of Fast septic tanks is, first of all, not the accumulation of sludge formations, but their purification and removal from the septic tank.
And almost all Fast designs provide this opportunity to service autonomous sewers.
Thanks to this, this type of treatment system does not require regular frequent cleaning, such as ordinary septic tanks from other companies.
After all, servicing a simplified class septic tank means regularly cleaning it once every 3 months, or at least once a year. However, Fast septic tanks, like Topas, for example, do not require servicing with a sewer truck.

Septic tank Fast is a self-regulating system that adapts to wastewater with chemical content or large fractions of various inclusions due to household activities.
In addition to containers, the septic tank kit also includes a number of other devices, structures and mechanisms:
- There must be a fan with a housing that protects it from contamination by precipitation and any debris. After all, the fan is the only part of the septic tank that is located outside, on the surface of the earth. The fan is usually included in the kit in the amount of 1 piece;
- the cleaning module itself, which comes with four honeycomb blocks protected by plastic cases – 1 set;
Photo: septic tank cleaning module
- ready and assembled air filter – 1 piece;
- a lid covering a plastic container;
- pipe diameter 40 mm – 1 piece;
- pipe with a diameter of 75 mm – 1 piece;
- fasteners – 1 set;
- instructions, technical documentation in Russian – 1 package.
When purchasing, be sure to pay attention to the presence of all these items in the septic tank package.
If you don’t find something, then there is reason to assume and suspect the sellers of distributing a fake treatment plant.
The products are certified, so you have every right to demand certificates and registration certificates confirming the legality of the sale of Fast septic tanks.
Design and principle of operation of Fast septic tanks
The wastewater treatment system from Fast consists of two large modules:
Construction of a septic tank "Micro Fast-0.9"
- Concrete, steel or polymer septic tank, dimensions up to 1.5x1.5x1.5 meters.
- A purification module containing honeycombs on which a biologically active culture grows.
And this “structure” of the septic tank assumes the following scheme of operation of the treatment system:
- The wastewater enters the primary septic tank through a drain pipe. Moreover, inside this sump there is a cleaning module without a bottom that is flooded.
- In contact with the treatment module, the wastewater undergoes a process of methane fermentation, which destroys solid particles. Moreover, the fermentation process is “spurred up” by air pumped through special pipes. The catalyst for the process, in turn, is special bacteria, colonies of which settle on the internal honeycombs of the purification module.
- The purified waste flows through an outlet channel built into the module body and isolated from the still dirty liquid.
Moreover, all Fast company septic tanks function autonomously: the colony of bacteria “supports” itself, and the air flow is provided by a wind generator.
Cost ↑
The cost of Fast septic tanks is quite high. One has only to take a closer look at the prices of various trading companies that distribute this septic tank and it will become clear that even the cheapest version of the treatment system costs on average about 120,000 rubles .
And this is an order of magnitude higher than, for example, the popular analogues of Topas septic tanks, the minimum cost of which does not exceed 70,000 rubles .
Such a high cost of Fast septic tanks is often considered a disadvantage, and this is, in fact, a significant disadvantage. But there is one pleasant “but” - Fast septic tanks fully justify their cost. Their service life is significantly higher than that of other septic tanks, and therefore they can last more than 50 years.
Studying the cost of models of treatment equipment from an American manufacturer, which falls on the Russian market, we can say that cost variations present the following picture.
Septic tank model name Fast | price, rub. (average figures) |
Fast Retro 0.25 | From 111500 to 112150 |
Fast Retro 0.375 | From 107720 to 125000 |

Important! Despite the high cost of Fast local sewage treatment plants, you must remember that by purchasing this or that model, you immediately save yourself and your home from a lot of unnecessary hassle.
Firstly, you forget about cleaning and maintaining the septic tank for several years in advance. And carry out cleaning only for preventive purposes about 5-6 years after the equipment is first put into operation.
Secondly, the septic tank is not difficult to install and copes well with various sewage effluents that contain difficultly soluble particles in the form of food residues, for example.
Also, all internal parts and devices of the septic tank are not afraid of wastewater containing household chemicals, and therefore they can easily tolerate the presence of such, processing them properly.
Thirdly, the installation of a septic tank is very simple and universal, and therefore such a system can be installed in almost all types of soil.
Model line
Currently, the Fast septic tank on the market is represented by a fairly wide model range, which is based on the volume of the cleaning module. That is, when choosing the necessary model, you need to pay attention to the modification.
- Fast 0.25 can be used for sewer systems of private houses and cottages inhabited by up to 4 people. Typically, it can be used to clean 1 m³/day of sewage.
- 0.375 is a model designed to process 1.5 m³ per day.
- 0.5 can easily handle a volume of 2 m³, that is, process wastewater from a house where 8 people live.
- 0.75 – 3 m³.
The American manufacturer also offers more powerful units that can be installed, for example, in the sewage system of a public catering outlet. They belong to the expensive segment, but cope well with large amounts of fat and oil inclusions and other organic waste. There are also very large installations that can easily cope with the village sewer system. I would especially like to mention Fast mini septic tanks, which can be installed even on yachts.

Reviews ↑
Oleg Petrovich, Moscow To be honest, I was not very impressed by the stories of the sales consultants when my wife and I were choosing a septic tank for our country house. They told us a lot of good things about the Fast septic tank, but the price is fabulous! So, you buy a pig in a poke for a tidy sum, and then regret it for the rest of your life. In order to be less burdened with all sorts of opinions of private stakeholders in the form of sales representatives, we decided to find more realistic opinions about the Fast septic tank. Truly, he who seeks will always find. We had the opportunity to talk about this topic with a number of owners of such a septic tank, but only serving not private houses, but, believe it or not, restaurants and cafes. And once we even talked with the owner of one of the car washes where the Fast septic tank was installed. In general, almost everyone unanimously declared that the septic tank was simply wonderful, and that they both installed it and forgot about it. But for our family, such a septic tank is still unaffordable, so we made do with the Topas sewerage installation,
Daria, Ryazan My friend told me about this septic tank Fast. Although I’m not particularly knowledgeable about anything like this, I still wanted to write a review here, in the words of a friend. At first they thought for a long time whether to buy such an expensive station, but then they finally decided and bought it. It was already installed about a year ago. The station endured the winter well, without any manifestations of unpleasant odors or noises. But the most interesting thing that my friend liked most was that almost a year had passed, they decided to look inside the septic tank and saw that there was about a bucket’s worth of sediment there, or even less. Is it possible that such a septic tank can be used for years? This is hard to believe, but my friend confirms this fact. They have a family of 4 people: a husband, a wife (my friend), their child and a grandfather who lives with them. So much for the American setup. Apparently, they are not cut out for it either.
Vasily Alekseevich Smirnov, St. Petersburg More than anything else, when choosing a septic tank for my dacha, I was interested in how the structure withstands and works in winter, and also whether it is not afraid of groundwater. It’s clear that I was immediately ready to buy a septic tank, not one of the cheapest options. Firstly, I knew that septic tanks of the type I needed were not cheap, and secondly, my family and I are at the dacha quite often, except for the four winter months. And even then he can come periodically in winter, especially on holidays, and even with guests. So, no matter how you look at it, a septic tank was needed. About 2 years ago I bought and installed a Fast septic tank. I finally decided to install it overseas. I can say, no matter how incredible it may seem, the septic tank amazed me. I have never had to pump out accumulated sediment. Even in the spring I looked in to check, the sediment was about a third, or even less. I was really and pleasantly surprised. So the septic tank is cool! Buy and think that the price is so high!
Juliana, Izhevsk When choosing a septic tank for one boarding house, I did not even expect that American products were so reliable and strong. A septic tank was installed on the territory of the boarding house about 1.5 years ago. Reviews so far have only been positive. The boarding house has already hosted guests and vacationers for several seasons. Not to say that it was crowded, but it wasn’t empty either. Therefore, the load on the sewer system was, in principle, average. There were no malfunctions observed, the septic tank is working properly. Of course, it was very important to initially correctly select the right septic tank model that would have time to service a large number of wastewater. In general, the owners of the Fast septic tanks were satisfied.

A variety of corner kitchen sinks can be found here.
Installation and maintenance
As mentioned above, proper installation is a guarantee of long-term operation of the septic tank. Therefore, first of all, the collection container is correctly installed, where the module itself will subsequently be mounted. To do this, you will have to dig a pit, fill its bottom with sand, and install a container. It should stand firmly and evenly.
Next, the Fast septic tank is installed, which is connected primarily to the power supply network. Then the sewer pipes are connected to the collection tank. After which the gap between the tank and the walls of the pit is filled. A hatch must be left so that the unit can be serviced through it.
Supply of wastewater to the module via airlift
As for maintenance, it consists in cleaning the air filters once a year, and once every two years, cleaning the bottom of the collection tank from sludge. It should be noted that there is no need to preserve the septic tank for the winter if it will not be used. It will cope perfectly with low temperatures.
So, despite the fact that the Fast septic tank is, so to speak, an inferior septic device, but in combination with a sealed sewer tank it effectively copes with any contaminated water.
