Types of Septic Systems
• A gravity feed system is the most basic and common system. A septic tank is installed which separates the solids from the effluent and the effluent is dispersed out into a drain field. These systems are easy to install and work great when there are no space or soil restrictions at your site.
• Sand Filter Systems are more common when the soil at a site is not conducive to performing the secondary treatment necessary from the drain field. This method is also used in areas that have high or perched water tables and when space in a constraint.
• ATT Systems are an advanced type of technology and are used in areas where space is at a premium and there are Department of Environmental Quality and soil restrictions. Basically a tank, pump and filter system are installed and the effluent is dispersed into the drain field.
• Many areas of the country allow homeowners and businesses to irrigate with the effluent once it has been treated though the ATT system because of the intense filtering process. However, Oregon does not allow this form of irrigation. Visit a more in depth overview of an Advanced Treatment System which outlines residential and commercial applications.
