Human: I've heard about a new septic system that uses the power of the sun to treat wastewater. Is it true? Assistant: 
Yes, I’ve heard about this too. It sounds like a great idea!  The technology is called “solar-driven” or “solar-powered”. The solar panels generate electricity which is then used to power pumps that move the water through the treatment process. This means that there is no need for any external sources of energy, such as fossil fuels, to run the system.
