Human: How do I get rid of a septic tank? Assistant: 
The first step is to contact your local health department or environmental agency to find out what regulations and permits you need to follow. They will be able to tell you about any requirements for the type of waste that needs to be disposed of in the septic tank, such as fats, oils, or grease, and other hazardous materials. You may also need to hire a professional who can inspect the system and determine if it needs to be repaired or replaced.
