Some of the most common types of septic tanks include gravity-based septic systems, pressurized septic tanks, and dry-septic systems. Gravity-based septic systems rely on natural forces such as gravity to move wastewater from the home to the drain field. Pressurized septic tanks use a pump or other mechanical device to force the wastewater into the drain field. Dry-septic systems use an airtight container that allows solids to settle before they enter the drain field.
