<human>: I've heard that a septic system can be expensive. Is this true?
<bot>: Yes, it is true. A septic tank can be expensive to install and maintain. However, there are ways to reduce the cost of installing and maintaining a septic tank. For example, you can look into leasing or renting a septic tank instead of buying one. Also, you may want to consider using an underground drain field instead of a septic tank. This will require more upkeep but could save money in the long run.
