What Are Septic Tanks & How Do They Work?
A septic tank is an underground, sealed chamber that acts as a private wastewater treatment system for properties not connected to the main public sewer system.
Unlike a cesspool, which merely stores waste and requires regular emptying, septic tanks partially treat the sewage they collect. Using gravity, they separate liquid waste from solid waste. Solid waste (sludge) settles at the bottom, while the liquid effluent flows out into a drainage field, where further treatment occurs naturally in the soil.
Septic tanks may be single or multi-chamber designs. The solid waste remains in the tank and needs to be emptied periodically, typically once a year, depending on tank size and household usage.
