<human>: I'd like to know what it takes to build a septic tank?
<bot>: Building a septic tank requires careful planning and preparation. You will need to determine the size of your tank, select a location for the tank, choose a type of septic system, and then install the tank according to local regulations. Additionally, you may also need to consider the cost of installation, soil conditions, and other factors that could affect the construction process. Finally, make sure you have proper maintenance plans in place so that the tank can function properly over time.
