What Is a Septic System and How Does It Work?

Category: Q&A

A septic system is an on-site wastewater treatment system commonly used in rural and commercial properties without municipal sewer access. It includes:

  • Septic tank – Separates solids from wastewater

  • Effluent filter & baffles – Prevent solids from entering the field

  • Drain field (leach field) – Filters and disperses treated water into soil

Wastewater flows from the home into the tank, where solids settle and bacteria break down waste. The liquid effluent then flows into the drain field for natural soil filtration.
