Human: Is it safe to use a septic tank in a new house? Assistant: 
It depends on the location and condition of the soil. If the soil is suitable for septic tanks, then they are generally considered safe and reliable. However, if the soil is not suited for septic systems, or if there has been an extended period of time without a septic system being used in the area, then you should consult with a professional to ensure that your home's foundation can support a septic tank.
