How should each well of a multiple-compartment commercial sink discharge?

In a commercial sink with multiple compartments, each well should discharge individually to a waste receptor. This approach is essential for maintaining proper plumbing function and hygiene standards. When each compartment has its own discharge, it allows for more meticulous handling of waste, ensuring that contaminants from different compartments do not mix.

This separate discharge system also facilitates easier maintenance and monitoring of each compartment's drainage, helping to prevent clogs and maintain effective drainage in each well. Furthermore, individual discharge routes can better accommodate local plumbing codes and regulations, which often emphasize the importance of segregating waste from different sources to protect the plumbing infrastructure and public health.

While discharging to a single waste receptor may seem efficient, it poses risks of cross-contamination between compartments. Direct discharge to a sewer or into a grease trap might not adequately address the specific drainage requirements or the potential for clogging, particularly in systems handling food waste where grease and solids can quickly accumulate. Therefore, the practice of having each well discharge individually is the optimal solution in commercial sink design.
