  • Class A –
  • Irrigation of crops to be eaten uncooked;
  • Landscape irrigation of all public green areas including but not limited to gardens, sport fields, golf courses and parks without access limitation; and
    • Washing of enclosures for animals.
    NOTE     The irrigation of crops refers to the application of treated wastewater prior to harvest.
    1. Class B – Irrigation of cereal crops, industrial crops, fodder crops, pasture, trees and crops to be eaten cooked only.
    NOTE: Rice is a cereal crop and sugarcane is an industrial crop.
    1. Class C –
    2. Localized irrigation of areas without public access; and
    3. Crops in Class B if exposure of workers does not occur.
    NOTE 1      Fodder crops and pasture are not included in Class C. NOTE 2      Areas without public access include forest and areas of vegetative recuperation. The standard does not provide the permissible limits for wastewater reuse for industrial or construction applications; cleaning roads or buildings; potable water or any other form of reuse not specified in this standard. Status: Current | Published: 2022]]>     This standard establishes the sampling, testing and maximum permissible limits (MPL) for key parameters related to wastewater reuse in the following classes pertaining to agriculture and landscape irrigation:

    1. Class A –
    2. Irrigation of crops to be eaten uncooked;
    3. Landscape irrigation of all public green areas including but not limited to gardens, sport fields, golf courses and parks without access limitation; and

The standard also specifies the nature and types of substances to be excluded from such effluents.
    This standard does not apply to:
    a) domestic wastewater discharges; and
    b) trade effluent discharged directly into the environment.

    NOTE: The standard does not address pre-treatment measures before discharge into public sewerage systems.

This standard applies to the effluent discharged from industrial processes point sources into the environment which includes conduits (man-made) which connect to the natural environment; it does not apply to the discharge of industrial effluent into sewerage systems operated by governmental entities or into wastewater treatment plants.

    This standard does not provide the permissible limits for the quality of effluents discharged into sewerage systems operated by governmental entities or into wastewater treatment plants. This standard provides references to the methods of sampling and examination of effluent.

    This standard does not provide details on the methods of treatment of industrial effluents nor on the design, operation or maintenance of the wastewater treatment plants necessary to ensure and maintain effluent discharged into the environment in compliance with the permissible limits specified in this standard.

    This standard does not apply to the discharge of effluent or liquid waste from any sea-going vessel of any type whatsoever, or from any floating craft, with the exception of an installation or device engaged in the exploration and exploitation of the resources of the sea-bed and the ocean floor and the subsoil thereof. The disposal of liquid or sludge wastes into underground disposal wells, once geologic and hydrogeologic conditions have been determined by the competent authority to be favourable for the type of wastes to be discharged, shall be excluded from the scope of application of this standard.
