What is a septic tank?

The septic tank played a crucial role in wastewater treatment. As we know, they contain hazardous bacteria and viruses.Тhe wastewater goes through various processes to be destroyed, most of which occur in the septic tank.

The septic tank is an underground chamber made of concrete, fiberglass, or plastic. It serves to receive and partially treat the wastewater that leaves your home. It undergoes anaerobic processes that break down nutrients and some solids. After that, the wastewater is divided into three layers- the scum, the effluent, and the sludge.

The Septic Tank Systems are a kind of simple local wastewater facility. They are usually used in villages and areas where there is no central sewerage. Many regions of the United States use different types of Septic Tank Systems.


How does it work?

When wastewater leaves your home through the pipes, it goes into the septic tank. The wastewater treatment processes begin in the septic tank. Beneficial bacteria will break down nutrients and some solid particles, and everything else will split into three layers.

All fats and oils form the top layer. It is known as scum. In the middle, the thickest layer is formed, which is a liquid called effluent. At the bottom of the septic tank, solid particles form a sludge. Once the septic tank has completed its task, the effluent is directed to the drainage field, where water purification continues.

The role of the septic tank is significant for any septic system. If it does not work correctly, then the system can not cope with all the necessary processes. It increases the risk of pollution of drinking water and the environment in general.

Elements/Components of the septic tank systems?

Septic Tank Systems have three main elements:

  • the septic tank
  • the drain field
  • the soil

As already mentioned, the septic tank is the first stop of wastewater. They remain in it long enough to break down the nutrients and divide the wastewater into three layers – a scum, a sludge, and a liquid called effluent.

When the sludge and scum are separated, the effluent leaves the septic tank and is discharged into the drain field. There, it undergoes additional purification and processing.

In cases where the drain field is overloaded with too much liquid, it will malfunction. The most common signs are flooding, bubbling, foul odors, wet spots around the drainage field, and many more.

Regular septic tank inspection, pumping, and cleaning can prevent such problems. Once the wastewater is treated in the drain field, it is soaked from the soil. In it, the effluent undergoes final treatment before going to groundwater.

The entire Septic Tank System is a living ecosystem that recycles wastewater without polluting the environment.

It is important to note that the elements of the Septic Tank System are interconnected. When one component does not work properly, it interferes with the other two. That is why it is essential to take the necessary care of your septic tank by contacting a licensed company for septic tank maintenance.


Types of system tanks?

There are two main types of Septic Tank Systems. These are:

  • Conventional Septic Systems
  • Alternative Septic Systems

The choice of the Septic Tank System depends on various factors. Some of the most important among them are the size of the site where the technicians will install the system, as well as environmental conditions- type and depth of soil, the presence of a rock base, the location of groundwater, etc.

To do this, you need to contact a licensed company to inspect and determine which is the most suitable Septic Tank System for you according to the given conditions.

The Conventional Septic System is a traditional septic system that has two sub-types: 

  • Тhe Gravity Systems consists of three elements. These are a septic tank, a drain field, and soil located under the drain field. This type of Septic Tank System uses gravity, which moves wastewater from the septic tank into the drain field. What is specific is that Gravity Systems have a distribution box that distributes wastewater into the pipes in the drain field;
  • The Pressure Distribution Systems are Septic Tank Systems that use a pump chamber. Through this chamber, the wastewater is collected, and the pump distributes the so-called effluent in the drain field pipes. This type of Septic Tank Systems also has a high-water alarm float, which turns on when the water level is too high.

On the other hand, the Alternative Septic Systems are suitable when the soil does not meet the requirements, and the groundwater is located high. This type of Septic Tank Systems has several varieties that work on different principles:

  • Aerobic Treatment Unit is a Septic Tank System that injects oxygen into the tank. It increases the natural bacterial activity and helps the process of better purification;
  • The Mound Septic Tank System is an alternative suitable for soils with no depth, a rock base soil, or high groundwater. This type of system ensures uniform distribution of wastewater, dosing, and rest cycles, as well as wastewater treatment in a sand filter;
  • The Sand Filter Septic Systems can be built above or below ground. The treatment process starts in the septic tank, after which the water goes to the pump chamber. After that, they are pumped into the sand filter. In it, wastewater undergoes three main treatment processes.

First, aerobic microbes absorb the nutrients, then the solids are filtered through a chemical process, and the contaminants adhere to the sand fill. When the wastewater goes through this whole process, it goes into the drain field, where it descends into the soil and flows into the groundwater.


Why do we need it?

As we mentioned, there are many settlements where there is no central municipal sewerage. Therefore, all wastewater coming from your home must be directed somewhere. The wastewater needs to go through various purification processes to not harm human health and does not pollute nature. 

In these cases, you must have the Septic Tank System installed. Its purpose is to dispose of wastewater to protect you and does not harm plants and animals. What type of Septic Tank System you choose depends on various factors.


What kind of problems can occur?

Problems with your Septic Tank System can always occur. The most common causes of malfunctions are improperly installed and maintained septic systems.

In most cases, problems arise in the septic tank and the drainage field. When your septic tank is not working properly, there are several main signs of this – bad odors, bubbling, slow drainage, wet spots around the drainage field, and others.

If you notice any of these signs, you should contact a professional company immediately. Neglecting existing system problems can harm your health and the environment.
