Okay kiddo, let me explain something very important. In every home, people use water for different things like bathing, washing dishes, and flushing toilets. After using this water, it becomes dirty and needs to go somewhere. This is where sewage collection and disposal comes in.
Sewage collection means that big pipes called sewers are underground and they collect all the dirty water from homes, businesses and other buildings. The sewers are like a big swimming pool for all the dirty water. When the water goes into the sewers, it flows until it reaches a place where it can be cleaned or treated.
Disposal means getting rid of something properly. So, when we talk about sewage disposal, it means that we take all the dirty water from the sewers and make sure that it doesn't harm our environment.
To do this, the dirty water goes through a process called treatment. Treatment plants have big machines that work like filters, which clean the dirty water from the sewers. They remove all the things that can harm the environment like bacteria and other bad stuff.
After the treatment, the water is safe to use again, but not for drinking. Some cities or towns use this water for things like watering plants or washing cars.
So, you see, sewage collection and disposal is very important, as it helps keep our environment clean and free from harmful things.
