How does a septic system work?

A system typically has 3 parts:

  1. Plumbing from the house: pipes that carry wastewater to the septic tank.
  2. A septic tank: a water-tight container for collection and initial treatment of wastewater.
  3. An effluent treatment system: an underground system for distribution into the soil, final treatment, and reintroduction of wastewater into the environment (effluent comes from the septic tank).
    • The effluent treatment system is usually a drainfield; also known as laterals, trench, absorption field or leach field.
