Some people believe that sewer pipes, septic tanks, and cesspools do not require cleaning during the cold season, assuming that low air temperatures negatively affect bacterial activity. In reality, this is not the case. First, the ground only freezes on the surface—about 1 to 1.5 meters deep. Everything below retains heat. Second, bacteria are far from the only issue. For example, sewer pipes tend to clog with grease all year round. Therefore, cleaning should never be neglected.
How to Unclog a Sewer?Of course, there is no need to physically access the pipes and manually restore their cleanliness. The modern market offers numerous effective solutions.Your best choice is biological products for cesspools, septic tanks, and pipes. These products are also known as bio-destructor agents.In this article, we will review several effective products worth considering. But first, let’s go over some theory.
What Needs to Be Cleaned in Sewer Pipes, Cesspools, and Septic Tanks

When it comes to sewer pipes, the list of potential contaminants can be quite extensive, as various types of debris end up in the system during daily activities—lint, household waste, hair, and more. However, the biggest problem is grease.
Even if a strainer is installed to catch small debris, grease is unavoidable. For example, it always enters the drainage system when washing dishes. Therefore, regular use of a pipe cleaning solution is essential.
Grease sticks to the inner walls of the pipes, forming deposits. If not removed, the problem will only get worse. These deposits trap hair, household waste, and other debris, significantly reducing the pipes’ capacity—especially during the cold season.
This issue is particularly critical for steel and cast-iron pipe systems. Owners of such systems must understand how to properly clean sewer pipes because these materials have rough surfaces that trap grease, preventing it from flowing further down the system.
For cesspools and septic tanks, the main issue is organic waste, which causes unpleasant odors. Septic bacteria operate on a biochemical level, breaking down organic matter and eliminating the root cause of the problem.
Now, let’s explore which biological cleaning products (bio-destructor agents) can effectively solve these issues.
EVOGEN G.T.

This is a liquid bio-product from the Step2Clean brand. It is designed to break down oils, fats, and petroleum products.
The bacterial blend present in EVOGEN G.T. produces lipase enzymes, which target large molecules of oil and fat. Under the influence of lipase, free fatty acids begin to be released, and pH decreases, creating an unfavorable environment for microbes. At the same time, broken-down molecules become a food source for EVOGEN G.T. bacteria, as the bacterial strains in EVOGEN G.T. are specifically selected to work effectively in low-pH ranges.
This product has strong advantages. For example, it does not interfere with the work of other biological agents, meaning you can use them in combination.
A special feature of this product is its cumulative effect. With regular use, EVOGEN G.T. neutralizes odors characteristic of drainage lines and grease traps.
These bacteria for fat breakdown are supplied in the form of a ready-to-use solution. No preparation is needed. You only need to shake the liquid before use.
The product is available in 250 ml and 1-liter bottles, as well as 10-liter canisters.
EVOGEN SEPTIC PLUS

These are bacteria for septic tanks, which are available in powder form. A distinctive feature is the presence of cellulase and other enzymes in the composition. Thanks to this feature, the product quickly breaks down organic waste and toilet paper. An optimally selected formula ensures maximum efficiency.
The biological product for sewer systems rapidly reduces the volume of organic waste. The fact is that the bacteria for septic tanks EVOGEN SEPTIC PLUS create a special biochemical environment, which accelerates the process of breaking down these wastes. Thanks to this product, you can eliminate the problem of unpleasant odor.
The product improves drainage and increases the efficiency of the septic tank, allowing for significantly less frequent calls for sewage disposal services. Moreover, if you use it regularly, the risk of pump failure in the septic system will significantly decrease, which usually requires large financial costs.
Both products are completely safe for humans and the environment. The composition does not contain aggressive chemicals or components that create toxic fumes.
