Waste Water - GCSE Geography Definition

Waste water is water that has been used and is no longer clean. It comes from homes, schools, businesses, and factories. This water might have soap, food scraps, chemicals, or even human waste in it. When people flush toilets, wash dishes, take baths, or even clean their cars, they create waste water. It's important to treat waste water before it's released back into nature so it doesn't harm the environment. This process involves special plants that remove the dirt, making the water safe to return to rivers or be reused. Understanding waste water is key to learning how humans impact the water cycle and the environment.
