Your septic system is an underground wastewater treatment structure, that’s most commonly used in rural areas and neighborhoods that don’t have centralized sewer systems. They’re used to treat wastewater from household plumbing systems like your bathrooms, kitchen drains, and washing machines.
While they’re most often called “septic systems” you might also hear them named:
onsite wastewater treatment systems
decentralized wastewater treatment systems
individual sewage disposal systems
private sewage systems.
A typical septic system is made up of a septic tank and a drain field, or soil absorption field.
The septic tank system is made to process and separate things like oil and grease from the solids in the wastewater. A soil-based system discharges the liquid from the septic tank into pipes that are buried in fields, chambers, or other special holding units that are made to slowly release the liquid into the soil. There are some alternative systems that are specifically designed to evaporate wastewater or disinfect it before it’s eventually released into the soil.
Here’s how a typical septic system works:
All of your household water is made to run outside of your house from one main drainage pipe into your septic tank.
Your septic tank is a buried, water-tight container that’s usually made of concrete, fiberglass, or polyethylene. Its designed to hold the wastewater while allowing solids to settle down to the bottom forming “sludge”, while its separated oil and grease float to the top.
The liquid wastewater then exits the tank into the drain field.
The drainfield is a shallow, covered, excavation made in unsaturated soil. Pretreated wastewater is discharged through piping onto porous surfaces that allow the wastewater to filter through to the soil. The soil then accepts, treats, and disperses wastewater as it percolates through the soil, finally discharging to groundwater.
Lastly, the wastewater percolates into the soil, naturally removing harmful bacteria, viruses and nutrients.
