What Constitutes a Failed Septic System?

A failed septic system cannot properly treat and dispose of wastewater from your home. This breakdown occurs when the system’s components—the septic tank, distribution box, or drain field—stop functioning effectively.

Why Septic Systems Fail

System design issues: Undersized for the home’s needs

Age: Most systems last 20-30 years with proper maintenance

Overuse: More wastewater than the system can handle

Inappropriate waste disposal: Flushing non-biodegradable items

Soil conditions: Clay or rocky soil that doesn’t drain well
