The maintenance and pit cleaning septics is required by law. Debris must be removed periodically, according to the capacity of the pit, and sent to treatment plants. For this reason, according to experts, the cleaning of septic tanks should not be done on their own, but by a Plumbing company that performs the pit cleaning.

“The procedure is carried out with pit cleaning trucks equipped with powerful vacuum pumps that suction the debris contained in the tank”, informs Gleison Pinheiro, director of PUMJIL, a company that provides sewer drain in Sao Paulo.

He says that, although it is present in the homes of millions of Brazilians, in general, the septic tank does not receive due attention and is surrounded by a series of doubts. With that in mind, the report organized the expert’s explanations about the importance of a company plunger and that performs the cleaning of pits in the following topics:

Cleaning the cesspool prevents the proliferation of pests

First, Pinheiro says that cleaning the cesspool is important because it prevents bad smells and the proliferation of pests, such as cockroaches and rats, which can transmit diseases.

Worldwide, there are about twenty species of domestic cockroaches. In Brazil, the most common are the francesinhas, known as sewage cockroaches: they carry bacteria, protozoa, fungi and viruses in their bodies. As a result, they can act as vectors for diseases caused by bacteria, such as furunculosis, leprosy, tuberculosis, poliomyelitis and diarrhea, according to information from the WHO (World Health Organization).

The presence of rats increases the risk of contamination by leptospirosis – a disease caused by the Leptospira bacteria, transmitted by direct or indirect exposure to rodent urine. In the country, there are three species of rats that are potentially harmful and inhabit urban centers: voles (Rattus norvegicus), roof rats (Rattus rattus) and mice (Mus musculus).

Preventive measures, such as regular cleaning of the septic tank, in conjunction with a company exterminator, are essential to prevent the proliferation of these pests. If the problem has gotten out of control, however, it is necessary to seek a specialized company to adopt procedures such as deratization.

Tank cleaning prevents waterborne diseases

Furthermore, the specialist continues, regular cleaning of the septic tank prevents waterborne diseases such as cholera, amoebiasis, parasitic infection of the colon, bacterial dysentery, cryptosporidiasis and giardiasis. “The presence of pathogenic microorganisms in water can lead to illness and cause symptoms such as severe diarrhea and dehydration.”

Pinheiro’s statement is supported by data from Datasus (Unified Health System): in 2019, there were 273,224 hospitalizations due to waterborne diseases in public hospitals. In addition, there were 2,733 deaths due to waterborne diseases across the country in 2019.

According to the balance of Datasus, the lack of sanitation was responsible for 80.6 million absences due to respiratory and waterborne diseases in the country.

“Cleaning the cesspool is essential to prevent various diseases that arise when the water or sewage does not undergo the proper cleaning treatment to eliminate pathogens. Once contaminated water or sewage comes into contact with humans due to flooding, blockages, accidental ingestion or because it is the only source available on site, you run the risk of getting sick”, he explains.

Pit cleaning prevents contamination of the environment

The month of June has come to be remembered as the month of the Environment since the UN (United Nations) established June 5 as World Environment Day, during a conference on the Human Environment held in Stockholm, capital of Sweden in 1972.

For the director of PUMJIL, the period calls attention to the responsibility that must be taken by companies and citizens, and care with the septic tank is one of the essential measures to ensure environmental preservation.

According to an unprecedented survey by MapBiomas – an initiative that brings together scientists and environmentalists to map the country -, published by the G1, Brazil has lost 15.7% of surface water in the last 30 years, equivalent to 3.1 million hectares of surface water Similarly, a balance sheet by the NGO SOS Mata Atlântica reveals that the water is bad or very bad in 40% of the 96 rivers, streams and lakes evaluated in seven Brazilian states.

According to the study, of the 278 monitored water collection points, only 18 (6.5%) have good quality, and no reservoir has reached optimal status.

To conclude, Pinheiro highlights that cleaning the pit prevents further damage to the structure, preventing accidents that can cause victims, in addition to financial losses.

“When used correctly and with proper periodic cleaning, this equipment becomes a key piece to avoid contamination of the soil, rivers and lakes, protecting not only the residents of the properties, but the environment as a whole”, he concludes. .
