1. The Basics of Septic Systems
Before we delve into costs, let’s recap what a septic system is. These underground wastewater treatment systems are commonly used in rural and suburban areas where centralized sewer systems aren’t available. Here’s how they work:
Septic Tank: The heart of the system, where wastewater from your home flows. Solid waste settles at the bottom, while liquid effluent moves to the next stage.
Drain Field (Leach Field): A network of perforated pipes buried in the soil. It disperses the treated effluent, allowing it to naturally filter through the ground.
Maintenance: Regular pumping and inspections are essential to keep your septic system functioning optimally.
