Sewage is a word we use to talk about waste or dirty water that comes from our homes, businesses, and other places. This waste includes things like toilet water, dirty dishwater, and other things we don't want in our homes. Sewage needs to be taken away and treated so it doesn't harm the environment or make people sick. Sewage can also be called "wastewater" or "septic waste." It is important to know about sewage so you can understand how to keep your home and community clean and healthy.
