This document specifies the principles of design, sizing, installation, identification, commissioning and maintenance of greywater systems with the purpose of use of greywater on-site.<\/p>\n

It applies preferably for the use of treated greywater for:<\/p>\n

    \n
  1. \n

    WC flushing;<\/p>\n<\/li>\n

  2. \n

    garden watering;<\/p>\n<\/li>\n

    laundry;<\/p>\n<\/li>\n

  4. \n

    cleaning purposes.<\/p>\n<\/li>\n<\/ol>\n

    This document also specifies the minimum requirements for greywater systems.<\/p>\n

    Excluded from the scope of this document are:<\/p>\n

      \n
    1. \n

      the use as drinking water and for food preparation;<\/p>\n<\/li>\n

    2. \n

      the use for personal hygiene purposes;<\/p>\n<\/li>\n
