For starters, a septic tank is to treat sewage from buildings. That’s by passing it through sewer pipes to the septic tank at the house. The sewage broken down with the help of bacteria to make it more effluent.
A domestic sewage treatment plant is a place, where contaminants removed from household sewage with the help of physical, chemical and biological processes to convert it into environmentally-safe wastewater.

However and while the wastewater that leaves a septic tank requires further treatment. Moreover, septic tanks do not require frequent servicing whereas sewage treatment plants do.
