Septic system failure means raw sewage backing up into your home through drains, toilets, and floor drains. This creates immediate health hazards and can contaminate your entire basement or lower level. The cleanup costs alone can exceed $10,000 before you even address the system failure.
When solids overflow into your drain field, they clog the soil’s ability to filter wastewater. This often requires complete drain field replacement, which involves excavation, new piping, and soil replacement. Total costs frequently reach $15,000-25,000 for complete system replacement.
Beyond the financial impact, failed septic systems violate Illinois health codes and can result in fines and legal action. You may be prohibited from using your home until the system is properly repaired and passes inspection.
