Where must commercial dishwashers discharge their waste?

Commercial dishwashers must discharge their waste to a waste receptor because this ensures that waste water is properly managed and directed to the appropriate waste disposal system. A waste receptor can be a trap or basin designed to receive liquid waste from various sources, including dishwashers. This setup helps prevent backflow and protects the plumbing system from potential damage caused by large volumes of wastewater or debris.

Discharging directly to a sink could lead to clogs or issues with the sink's drainage system, while a grease interceptor is specifically designed for trapping grease and oil from cooking activities, not necessarily for dishwasher waste. Connecting to a floor drain may not provide the necessary filtration or separation required by plumbing codes. Therefore, routing wastewater from a dishwasher to a waste receptor is considered best practice, meeting sanitation standards and ensuring efficient waste management.
