System Types

Not every septic system is a tank and a gravel trench. Soil, lot size and the water table decide which design a property gets, and each one has its own price and upkeep.

7 guides

Start with our comparison of septic system types: conventional, chamber, mound, aerobic and more, plus how to work out which one is already in your yard.

The detailed guides go further. Aerobic systems treat wastewater well but come with a service contract. Nitrogen-reducing systems are now required in some coastal and watershed counties. A grinder pump moves waste uphill when gravity cannot. We also explain how a cesspool differs from a septic tank, compare septic and city sewer over 20 years, and price the switch to sewer when the main reaches your street.

The quickest way to confirm your own system type is the permit on file with your county health department. It usually names the design.
