Greywater is the term used for wastewater generated from household activities, excluding toilet waste. It typically comes from sources like sinks, showers, and washing machines. This type of water can contain soap, dirt, and food particles but is generally less contaminated than blackwater, which comes from toilets. Recycling greywater can help conserve fresh water and reduce the burden on sewage systems. Many households use greywater systems to collect and treat this water for irrigation or toilet flushing. Proper treatment and management are essential to ensure safety and prevent health risks associated with using greywater.
