What is the difference between a septic system and a sewage treatment system?
assistant
A septic system is a type of wastewater treatment system that uses biological processes to treat wastewater. It consists of two components: a septic tank, where solids settle out; and a drain field, which is an area where the treated wastewater is dispersed into the ground. Sewage treatment systems are similar in that they both use physical, chemical, and biological processes to treat wastewater, but they differ in that a sewer system transports wastewater directly to a water treatment plant, whereas a septic system treats wastewater on-site.
