Protecting Your Septic System: What Not to Flush in Appleton

What not to flush with septic system

Your septic system is a living ecosystem. Billions of bacteria work around the clock to break down waste. But certain items can kill these bacteria and damage your system.

Items to Never Flush

  • Cooking grease and oil — solidifies and clogs pipes
  • Harsh chemical cleaners — kill beneficial bacteria
  • "Flushable" wipes — do not break down in septic systems
  • Feminine hygiene products — do not break down
  • Diapers — even biodegradable ones don't break down quickly enough
  • Coffee grounds — accumulate as sludge
  • Cat litter — designed to clump and will clog your system
  • Medications — introduce chemicals and can contaminate groundwater
  • Paint and solvents — kill bacteria and contaminate groundwater
  • Cigarette butts — don't break down and contain toxins

What Is Safe to Flush?

Only human waste, septic-safe toilet paper, and water. That's it.
