GB/T 18919-2002 establishes a classification system for reclaimed water from urban wastewater treatment, defining categories based on end-use applications such as agricultural irrigation, industrial cooling, urban landscaping, and recreational water. It is applied by municipal water authorities, environmental agencies, and engineering planners in China to standardize the quality and management of recycled water for non-potable purposes. This standard supports the safe and efficient reuse of treated urban wastewater, reducing freshwater demand in water-scarce regions.
