A septic system works by collecting wastewater from your home's plumbing and allowing it to settle in the septic tank. The solids settle to the bottom and are broken down by bacteria. The liquid flows through the outlet pipe and is filtered through the drain field before being absorbed into the soil.

To keep a septic system functioning properly and to avoid costly repairs or environmental damage, several items should never go into it. Here’s a list of what you should avoid putting into a septic system:

• Paper towels, tissues, wipes (even "flushable" ones): These don’t break down like toilet paper and can clog your system.
• Sanitary products: Tampons, pads, and diapers can cause blockages.
• Plastics or other synthetic materials: These will not break down and can damage the system.

• Harsh household cleaners: Bleach, ammonia, and other strong cleaning agents can kill beneficial bacteria in the septic tank.
• Paints, solvents, and thinners: These can contaminate groundwater and interfere with the natural breakdown of waste.
• Antifreeze, gasoline, motor oil: Any kind of automotive fluid is hazardous to the system and environment.

• Medications: Prescription or over-the-counter drugs can disrupt the balance of bacteria in the septic system.
• Antibiotics: These can kill the beneficial bacteria necessary for breaking down waste.

• Grease, fats, oils: These can solidify and cause blockages in pipes or form a scum layer that interferes with the septic system’s operation.
• Coffee grounds, egg shells, and other non-decomposable food scraps: These materials don’t break down easily and can fill the tank faster than necessary.

• Laundry or dishwasher overuse: Running multiple loads back-to-back can overload the system, making it difficult for the tank to process wastewater.
• Water softener backwash: The salts used in water softeners can harm the septic system.

• Hair: Hair clogs pipes and does not break down in the septic tank.
• Dental floss: Like hair, it does not decompose and can tangle around septic components.

• Cat litter: It contains clay and sand, which can clog and damage the system.
• Cigarette butts: These contain harmful chemicals and do not decompose easily.

Keeping these materials out of your septic system helps prevent clogs, damage, and environmental hazards. Regular maintenance and mindful usage are key to extending the lifespan of the system.
