<human>: I'd like to know what it takes to build a septic tank?
<bot>: To build a septic tank, you will need a permit from your local government. You'll also need access to the land where the tank is to be built and construction materials such as concrete, steel, and plastic. Additionally, you may require specialized tools and equipment depending on the size of the tank you are building. Finally, you should have knowledge of how to properly install the tank and maintain it for proper functioning.
