grey water
Grey water is the term used for wastewater that comes from household activities, excluding toilet waste. This includes water from sinks, showers, bathtubs, and washing machines. Grey water can be reused for non-potable purposes, such as irrigation or flushing toilets, which helps conserve fresh water resources.
Unlike black water, which contains harmful pathogens and requires more extensive treatment, grey water is generally less contaminated. However, it still needs to be managed properly to prevent health risks and environmental issues. Many households are exploring grey water recycling systems to promote sustainability and reduce water consumption.
