Understanding Septic Systems 

A septic system serves as your property’s private wastewater treatment facility. This underground system processes household waste through a combination of natural and technological methods. 

Key Components of a Septic System: 

• Main Tank: A watertight container that separates solids from liquids 

• Distribution Box: Directs wastewater flow to the drain field 

• Drain Field: A network of perforated pipes that filter wastewater 

• Soil: Acts as a natural filter for final water treatment 

Your septic system operates through a systematic process. When wastewater enters the main tank, heavier solids sink to form sludge while lighter materials float as scum. The clear water between these layers flows into the distribution box and disperses through the drain field for final filtering.
