As a homeowner, you depend heavily on your septic tank. While this system is important, few people give thought to how it works. However, this knowledge is valuable, as being more familiar with your system can help you ensure it is working properly and even help you avoid septic tank repairs. Here’s what you need to know. 

What Is the Tank’s Primary Function?

septic tankA septic system has one purpose: to collect the waste deposited from homes via drainage pipes. It is used instead of the traditional sewer system. They could be thought of as sewage systems for individuals rather than communities. The typical tank is made from concrete, polyethylene, or fiberglass. It’s not uncommon for them to hold over 1,000 gallons. The tank collects wastewater, receiving it from one end and filtering it out the other. These systems are passive, meaning they only require gravity to work.

Where Does Waste Travel After Leaving the Tank?

A septic tank is designed to hold waste so it can be filtered. Solids are filtered to the bottom to form the sludge layer, whereas oil and grease float to the top to form the scum layer. When new liquid wastewater comes into the tank, the existing water is released to the drain field. This part of the system consists of covered, perforated pipes—around 4 inches in diameter—that are buried between 4 and 6 feet deep. The water is then absorbed by the soil, where harmful Coliform bacteria and viruses are removed. The size of the drain field is related to the ground’s absorption properties. For example, if the ground is made of clay, which absorbs water slower, the drain field will be bigger.
