Septic systems
Septic Systems
A Septic System (pronunciation: /ˈsɛptɪk ˈsɪstəm/) is a type of small-scale sewage treatment system common in areas with no connection to main sewage pipes provided by local governments or private corporations.
Etymology
The term "septic" comes from the Greek word "septikos" which means "rotten" or "putrefying". This refers to the anaerobic bacterial environment that develops in the tank and decomposes or mineralizes the waste discharged into the tank.
Components
Septic systems are typically composed of two main parts: a Septic Tank and a Drain Field.
- The Septic Tank is a watertight box, usually made of concrete or fiberglass, with an inlet and outlet pipe. Wastewater flows from the home to the septic tank through the sewer pipe.
- The Drain Field (also known as a leach field, disposal field, or a soil absorption system) is a component of a septic system that removes contaminants from the liquid that emerges from the septic tank.
Related Terms
- Anaerobic Bacteria: These are bacteria that thrive in environments where there is no oxygen. They play a crucial role in breaking down the waste in a septic system.
- Effluent: This is the liquid waste or sewage that is discharged out of a septic tank and into a drain field.
- Scum Layer: This is the layer of fats, oils, and other lighter-than-water substances that float to the top of the contents of a septic tank.
- Sludge Layer: This is the layer of heavier-than-water solids that sink to the bottom of a septic tank.
