Septic tanks and cesspools remain relevant and quite common structures for ensuring autonomous sewage systems in country houses and summer cottages. Indeed, the problem of organic waste disposal outside the city is quite acute. Owners of such systems know very well how important it is to maintain efficient operation. After all, constant calls to the septic service, self-pumping of wastewater, and suffocating unpleasant odors are rather questionable pleasures. Especially on the eve of the spring-summer season, filled with warmth, blooming, freshness, gardening work, or relaxing in the company of friends.
A bacterial-based septic treatment helps to deal with the difficulties and problems of cesspool operation in one stroke. And even if the sewage system has never encountered septic bio-products before, now, in the warm season, is the perfect time for an introduction. Let’s figure out what septic bacteria are, how these microscopic workers function, and why they are so relevant in the spring-summer season.
How does it work? Simple talk about bacteria in the septic tank

A bacterial-based septic treatment, when it enters the depths of the system, turns it from a simple waste container into a whole microscopic plant for processing them. And the best bacteria for septic tanks are the main workforce at this plant.
The principle of live bacteria’s action is based on the natural process of biodegradation. When bacteria enter the septic tank, rich in organic matter, they actively produce enzymes. These enzymes act as biological catalysts. Their task is to break down organic matter into simpler and smaller fragments. It’s like a complex puzzle that enzymes can disassemble into individual pieces.
After decomposition, these “pieces” are used by the bacteria as a source of energy. Simply put, they become food. Thus, bacteria not only destroy waste but use it as a resource to increase their population. And the more bacteria there are, the more efficient the process becomes. As a result, only water, carbon dioxide, and non-toxic sludge remain in the cesspool. And thanks to the reduction of nitrogen-containing substances, the odor is almost completely neutralized.
Which bacteria are best for septic tanks?
Effective septic operation is a multi-stage process, where each type of bacteria plays its important role. In the upper layers, aerobic microorganisms are actively working — they require oxygen to function. At the same time, for deep processing of organic waste in an oxygen-free environment, anaerobic bacteria are necessary. They ensure the complete decomposition of complex substances, completing the purification process and minimizing sludge formation.
This is exactly how the Evogen Septic Plus powder from Step2Clean works. Microbiologists have selected the best bacteria for septic tanks for this purpose. A unique mix of five different strains with high destructive potential ensures perfect results. The microorganisms in the product successfully cope with their tasks at temperatures from +5°C to +50°C. An ideal choice for the climate conditions of Ukraine.
Summer “upgrade” of the septic system with Step2Clean’s bio-product
Evogen Septic Plus powder successfully decomposes organic matter and neutralizes odors even in the cold season. However, it is the temperature rise that maximizes its effectiveness. And there are several reasons for that. Let’s take a closer look.
Temperature — the key to metabolism
Recalling the school biology course, we can identify the first factor contributing to the increased efficiency of the bioactivator. It is enzymatic activity and a powerful energy boost for living organisms in a warm environment. It is during the summer that the temperature in the septic tank reaches the optimal range for bacterial work. Of course, it’s worth buying anaerobic bacteria for the septic tank even in colder times. The situation looks roughly like this:
In the cold, enzymes are like sleepy waiters in a half-empty restaurant. They’re ready to serve but move more slowly than usual. On the other hand, there’s less waste in this “restaurant” in winter. So, the bacteria’s winter efforts are quite enough to cope with the load.
When warmth returns, the situation changes dramatically. Bacteria get to work like a powerful engine that has received high-quality fuel. They begin to break down fats, proteins, carbohydrates, and other organic compounds that enter the septic tank with double or even triple the strength.
The bacteria’s “digestion” speed formula
When examining how septic powder works, we can’t ignore reaction kinetics. According to the laws of chemistry, increasing temperature accelerates reactions. And the breakdown of organic waste is essentially a cascade of biochemical reactions catalyzed by bacteria.
Highly educated intellectual show-offs describe this using the Van’t Hoff rule. But avoiding polemics, we can reduce it to this principle: raising the temperature by every 10 °C on average doubles the speed of chemical reactions.
Viscosity of the medium as a factor of efficiency
In addition to affecting bacterial activity and reaction speed, temperature also influences the waste itself. A specific field of physics called rheology studies the flow properties of substances under various conditions. Based on research, scientists found that with temperature increase, the viscosity of liquids decreases. This means organic compounds become more “mobile” and accessible to bacteria.
To put it simply, it’s like trying to stir cold jelly versus warm liquid pudding. In the first case, you’ll need to use a lot of force, and the spoon moves slowly. In the second — everything goes easily and smoothly. The same happens in the microscopic world of the septic tank or cesspool.
Geometric progression of cleanliness: when the “crew” grows and thrives

In favorable conditions, with a comfortable temperature and sufficient nutrients (and in summer, there’s plenty of that in the septic tank), bacteria reproduce at an astounding rate. Math calls this exponential growth: each bacterium divides into two, those two into four, and so on. As a result:
- more bacteria — more enzymes produced;
- more thorough coverage of the substrate and contact with organic waste;
- reduced risk of decomposition “stagnation.”
