New non-potable water standard outlines safety guidelines

Due to the inherent health risks associated with the use of non-potable water, CSA Group has published 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 (2650 gallons-per-day) or less; site-assembled components included in the non-potable water treatment system; test methods for the performance of the plants; minimum requirements for materials, design and construction, markings; and instructions and other documentation.
