Floor drains in walk-in coolers must discharge to what type of drainage system?

Floor drains in walk-in coolers must be connected to a separate drainage line to ensure that any condensate, food debris, or wastewater generated in the cooler does not contaminate the general sewage system or other drainage systems. A separate drainage line allows for better management of specific waste characteristics from food storage areas, reducing the risk of grease buildup and potential hygiene issues. This helps maintain sanitary conditions while adhering to health and safety regulations outlined in plumbing codes.

Connecting to the main sewer line or a storm drain system would not only pose contamination risks but might also lead to blockages or other plumbing issues as these systems are designed for more general use rather than specialized drainage. Discharging directly to the street could create hazardous conditions and would violate regulations, ensuring that proper plumbing practices are followed. Thus, utilizing a separate drainage line is the most appropriate and compliant solution for the wastewater produced in walk-in coolers.
