What is an onsite sewage system?
What are typical sewage system components?
- Pipe From House: All of your household wastewater exits your home through a pipe that flows into the septic tank. The following graphic shows sewage system components.
- Septic Tank: The septic tank is a buried, watertight container. It holds wastewater long enough for solids to settle out (sludge) and for oil and grease to float to the surface (scum). Solid materials begin to decompose, and anaerobic breakdown of bacteria takes place. Compartments and a baffle or outlet tee in the septic tank prevent the sludge and scum from leaving the tank and entering the drainfield. The septic tank needs to be pumped every 3-5 years to remove the scum and sludge.
- Drainfield: Every time new wastewater enters the septic tank, the same amount of wastewater (or effluent) exits the tank and is pushed into the drainfield. If the drainfield is overloaded with too much liquid, it will flood. This prevents treatment of wastewater, and may cause sewage to flow to the surface of the ground or back up into the house. A reserve drainfield is an area on your property suitable for a new drainfield system if your current drainfield fails.
- Soil: Septic tank wastewater flows to the drainfield, where it percolates into the soil and is filtered. Natural processes remove most of the contaminants in the wastewater before it eventually reaches groundwater. Aerobic breakdown of bacteria also occurs. Soil that allows for percolation, or drainage, is necessary for successful wastewater treatment.
