Due to the inherent health risks associated with the use of non-potable water, CSA Group has published CSA B128.3 - Performance of Non-Potable Water Treatment Systems – which specifies water systems requirements for treating greywater or waste water for reuse in other applications. This new standard covers:

  • Non-potable water treatment systems for wastewater or greywater intended for treatment applications with a capacity of 10,000 litres-per-day (2,650 gallons-per-day) or less
  • Site-assembled components included in the non-potable water treatment system
  • Test methods for the performance of the plants and minimum requirements for materials, design and construction, markings, instructions and other documentation.

CSA B128.3 complements another CSA Group standard: CAN/CSA-B128.1/B128.2 - Design and Installation of Non-Potable Water Systems/Maintenance and Field Testing of Non-Potable Water Systems. This dual-standard is an installation guide specifying the design, installation, maintenance and field testing of non-potable water systems. Both standards target manufacturers and other users of non-potable water reuse products and can be used for conformity assessment of products.
