Grey water is the term used for wastewater that comes from household activities, excluding toilet waste. It typically includes water from sinks, showers, bathtubs, and washing machines. This type of water can contain soap, dirt, and food particles but is generally less contaminated than black water, which comes from toilets. Recycling grey water can be beneficial for conserving water and reducing the demand on sewage systems. It can be reused for irrigation, flushing toilets, or even washing clothes, depending on local regulations and treatment methods. Proper management of grey water helps promote sustainable water use in households.
