Which approach is inadequate when discharging wastewater from kitchen appliances?

• A. Using an air break
• B. Discharging directly to the sewer
• C. Storing wastewater prior to discharge
• D. Using a trap system

Answer: (B)

Discharging wastewater directly to the sewer is considered inadequate because it does not incorporate any measures to prevent backflow or contamination. A direct discharge method can allow for potential sewage gases to infiltrate the kitchen area, posing health risks and sanitary issues. Additionally, without proper filtration, solids or contaminants in the wastewater could interrupt the sewer system's functionality and potentially cause blockages or other problems within the municipal sewer lines. In comparison, other approaches like using an air break create a physical gap that prevents backflow, thus safeguarding the potable water supply. Storing wastewater before discharge allows for proper treatment or disposal methods to be implemented, and using a trap system helps in retaining solids and preventing sewer gas from entering the building. Each of these systems incorporates safety and sanitary measures that are vital for effective wastewater management.
