A sewage farm is a place where all the yucky water from our homes and buildings goes to get cleaned up so it doesn't hurt the environment.
The water from our toilets, sinks, and showers is called sewage, and it's full of things that can make people and animals sick if it's not cleaned up properly.
At the sewage farm, the sewage goes through a lot of different processes to make it safe to go back into nature.
First, big screens catch any big things like sticks or toys that accidentally got flushed down the toilet.
Next, the water goes through some tanks where tiny organisms like bacteria and fungi eat up all the gross stuff like poop and food scraps.
After that, the water is checked to make sure it's clean and free of harmful germs.
Finally, the cleaned water can be released back into rivers, lakes, or oceans, and the solid waste is taken away to a different spot to be disposed of safely.
It may not always smell the best or look pretty, but sewage farms are super important for keeping our environment clean and healthy.
