JCW Treatment Wastewater Treatment Tour - Definition 1.
Wastewater is used water.
If you turn on your faucet and wash your hands, run the garbage disposal, take a shower, or flush the toilet, once it s in the drainpipe it becomes wastewater, which is also, called sewage. Before the used water can be put back into rivers and streams it needs to be cleaned. The process of cleaning the used water is called wastewater treatment. Treating the wastewater helps make the rivers and streams safer for people, fish, plants, and other living things. Sometimes we call treatment a defense against water pollution.
