Protecting Your Septic System: What Not to Flush in Appleton
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.
