Gravity System

Basic or standard system, uses gravity to move effluent through the septic tank and into the drainfield.


Pressure Distribution System

Has a pump which distributes effluent throughout the drainfield at the same time. Used in most new systems because it makes better use of the entire drainfield.


Mound System

Installed when minimal soil is available for treatment, drainfield is raised above ground level


Sand Filter System

Has a sand filtering system and pump to treat and disburse effluent, used when minimal soil is available for treatment.


(ATU) Aerobic Treatment Unit

Uses oxygen to break down solids, producing cleaner wastewater than conventional types. Often used in environmentally sensitive areas where effluent requires more treatment before entering the drainfield.
