1. A water distiller can be used to convert wastewater into clean water.
2. The fertilizer generator can be used to turn wastewater into fertilizer and release natural gas, which can be used to generate electricity.
3. Hydroponic agricultural tiles can be used to grow crops that require wastewater irrigation. Use an electric water pump to extract wastewater and connect it to hydroponic agricultural tiles with water pipes. Note that some crops require waste water and others require clean water.
