Septic System 101: How Your System Works

Understanding how your septic system functions is key to proper maintenance and avoiding costly repairs. Here's a quick primer:

Wastewater from your home flows into the septic tank, where solids settle to the bottom (sludge) and fats/oils rise (scum layer). Anaerobic bacteria treat the waste, allowing the liquid effluent to exit into the drain field.

The drain field's perforated pipes disperse this liquid into the ground, where it's naturally filtered by the soil. Sludge accumulates and eventually the tank needs pumping to remove it.

Aerobic systems use an aeration unit instead of a drain field to further treat effluent before dispersal. Both require routine professional service to operate successfully.
