I've been hearing a lot about septic tanks and septic systems. What are they and how do they work?

Septic tanks and septic systems are designed to treat and store wastewater from homes, businesses, and other buildings. They are made up of several components that help remove contaminants from the water before it is released into the environment. The tank is typically made of concrete or plastic and holds the wastewater until it can be treated by bacteria in the tank. After the wastewater has been treated, it flows out of the tank through pipes and then into a drain field where it is dispersed into the soil. This helps prevent contamination of surface water and groundwater supplies.
