There are two basic septic system types — conventional and alternative. Site and soil conditions generally determine the type of system that should be installed. Since your septic system is your responsibility, it is important to understand your particular type of system and how to care for it. The following is a brief explanation of the most common types of septic systems.
Basic or standard system, uses gravity to move effluent through the septic tank and into the drainfield.
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. Alternative Systems
Aerobic Treatment Unit (ATU)
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. 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. TGlendon® BioFilter
This alternative system consists of different layers of sand and gravel placed in a watertight box. Sewage effluent is pumped into the bottom of the filter and then works its way up through the sand and out into the soil.
In this system, the effluent is filtered through a bed of engineering textile material that is enclosed in a watertight container. This allows treatment of a large amount of wastewater in a small space and is clean enough for subsurface irrigation.
This is a shallow, pressure-
