What is the primary purpose of a septic system?

The primary purpose of a septic system is to treat and dispose of wastewater from residential or commercial properties. This system is designed to handle the effluent generated from toilets, sinks, showers, and other drains within a property. The core function involves both the separation of solids from liquids and the biological treatment of the wastewater, allowing it to be safely absorbed into the soil through a drain field.

The septic tank initially collects the wastewater, where solids settle at the bottom while anaerobic bacteria break down organic matter. The liquid effluent is then released into the drain field, where it is further treated through natural filtration processes as it percolates into the ground. This method ensures that harmful pathogens and contaminants are effectively reduced before the water re-enters the groundwater supply.

Understanding the role of a septic system is vital for ensuring proper maintenance and compliance with local regulations, which ultimately helps protect public health and the environment.
