Septic tank
Storyboard 
A septic tank is an on-site wastewater treatment system used in areas without centralized sewer systems. It consists of a buried container made of concrete, fiberglass, or plastic, designed to receive, treat, and partially treat household wastewater. The tank operates as a two-chamber system, separating solids and scum from the wastewater. In the first chamber, larger solids settle to the bottom, forming sludge, while lighter materials float to the top as scum. The first chamber functions as an anaerobic zone, breaking down organic matter. The partially treated effluent then flows to the second chamber for further settling and biological treatment. This process helps remove more solids and pathogens, improving the quality of the effluent before it leaves the septic tank.
