The Washington County Environmental Health Program 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 drainfiled 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.
