Septic tank
Septic Tank
A Septic Tank (/ˈsɛptɪk tæŋk/) is a key component of a septic system, which is a 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" refers to the anaerobic bacterial environment that develops in the tank and decomposes or mineralizes the waste discharged into the tank. "Tank" refers to the storage component of the system.
Function
Septic tanks can be coupled with other on-site wastewater treatment units such as biofilters or aerobic systems involving artificially forced aeration.
Construction
Septic tanks are typically made of concrete, fiberglass, PVC or plastic, and can be rectangular or cylindrical in shape.
Maintenance
Regular maintenance of a septic tank is crucial to prevent system failure. This includes regular pumping to remove the buildup of solids in the tank.
