How does a septic tank system actually work?

A septic tank system in Los Angeles is an underground wastewater treatment structure. It uses a combination of natural processes and a septic tank to treat sewage. Solids settle to the bottom, forming sludge, while grease and lighter materials float to the top as scum. The liquid wastewater, called effluent, then flows out to a drain field for further treatment in the soil.
