assistant
The primary difference between a septic tank and a sewage treatment plant is that a septic tank treats waste water from a home or building, while a sewage treatment plant treats wastewater from an entire community. A septic tank typically consists of a concrete tank with a lid to contain the waste material inside, while a sewage treatment plant includes additional equipment such as filters, pumps, and other mechanical devices to further purify the wastewater.
