How your System Works
A septic system has two major components: a septic tank and a drain field. Wastewater sewage flows from the house to the septic tank. The tank retains the solids while the excess water flows off into the drain field. You may have a traditional drain field also known as a trench (this is the most common type of drain field), a seepage pit (dry well), a sand mound system or a drip system.
