Start a Sewage Treatment Plant Manufacturing
A sewage treatment plant (STP) is a system that cleans dirty water coming from homes, factories, schools, and offices.
When we use water in bathrooms, kitchens, or factories, it becomes dirty. This dirty water is called sewage. If we throw it directly into rivers, it harms fish, animals, and humans.
So, sewage treatment plants clean this water before releasing it back into nature.
