<human>: I've heard about a new septic system that uses the power of the sun to treat wastewater. Is it true?
<bot>: It’s true, but there are some limitations. The system works by using solar panels to heat up water and then running it through a pipe network that contains bacteria that breaks down organic matter in the wastewater. This process produces methane gas which is collected and used as fuel for the generator that powers the system.
