Washington County Environmental Health issues septic system permits for households that are not served by public sewer. These households usually depend on septic systems to treat and dispose of wastewater. A septic system has three main parts: the septic tank, the drainfield and the soil. A septic tank separates solids from wastewater and stores and decomposes the solid matter. The resulting liquid discharged from the septic tank seeps into a drainfield. The bacteria present in the soil below the drainfield complete the final treatment of the wastewater. The soil also determines which type of septic system is suitable for a property.
A malfunctioning septic system is a health hazard; properly functioning septic systems treat sewage to prevent ground and surface water pollution.
