<human>: What is the difference between a septic system and a sewage treatment system?
<bot>: The primary difference between a septic system and a sewage treatment system is that a septic system uses natural processes to treat wastewater, while a sewage treatment system relies on mechanical or chemical processes to remove pollutants. A septic system typically consists of a septic tank, distribution box, soil absorption field, and drainfield. These components are all connected together in order to filter out contaminants before the water is discharged into the ground. In contrast, a sewage treatment system typically includes a series of tanks, pumps, and filters that use physical, biological, and chemical reactions to cleanse wastewater.
