Greywater refers to wastewater collected from sinks, showers, bathtubs, washing machines, and other non-toilet plumbing fixtures. Unlike blackwater (which includes sewage from toilets), greywater contains fewer pathogens and contaminants, making it suitable for reuse in irrigation, landscaping, and toilet flushing after proper treatment. Reusing greywater is part of water conservation efforts, as it reduces overall water consumption and relieves pressure on municipal wastewater systems. Greywater systems typically involve filtration, sedimentation, and disinfection to make the water safe for non-potable applications. Proper design, installation, and maintenance of greywater systems are essential to prevent health risks, ensure compliance with plumbing codes, and promote sustainable water management.
