What type of waste should never be disposed of in a septic system?

The disposal of grease, chemicals, and non-biodegradable items in a septic system should be strictly avoided due to their detrimental effects on the septic system's functionality and the environment. Grease can solidify and clog pipes, leading to backups and system failure. Chemicals can kill the beneficial bacteria that break down organic waste, disrupting the delicate balance necessary for proper septic operation. Non-biodegradable items, such as plastics and certain household products, do not decompose and can accumulate in the system, causing further blockages and issues.

In contrast, food waste, while it should be minimized to prevent overload, can break down naturally, and certain types of papers, like cardboard, can also be composted or break down over time. Organic garden waste, if managed properly, can add beneficial microorganisms and nutrients to the system. Therefore, understanding the proper management of different waste types is crucial for maintaining an effective and environmentally sustainable septic system.
