What happens to the water you use to take a bath? Where does the water go after you use it to wash your clothes, or clean vegetables, fish and meat?  The used water is called wastewater, which includes food scraps, oils, soaps, chemicals and even human waste. In homes, this also covers water from sinks, showers, bathtubs, toilets and washing machines. Economic activities (such as agriculture, manufacturing, mining, and institutions like offices, hospitals and schools) produce wastewater that has to be collected and treated to avoid environmental pollution and health risks.
