What materials should not be disposed of in a septic system?

The correct answer highlights the importance of maintaining the integrity and functionality of a septic system. Septic systems are designed to treat and manage human waste and certain biodegradable materials, but they are not equipped to handle harmful substances.

Chemicals such as solvents, paints, pesticides, and cleaners can disrupt the natural processes that break down waste in a septic tank. These substances can kill beneficial bacteria that are essential for the breakdown of organic materials, leading to system failure and potential environmental contamination. Non-biodegradable items, such as plastics and metals, do not decompose and can cause blockages in the system, leading to costly repairs and maintenance.

Understanding what should not be disposed of in a septic system is crucial in preventing damage and ensuring that the system operates efficiently. This knowledge helps protect both the homeowner's investment and the surrounding environment.
