High temperature wastes should be cooled to what temperature before discharging?

• A. 120F
• B. 130F
• C. 140F
• D. 150F

Answer: (C)

High temperature wastes should be cooled to 140°F before being discharged to ensure compliance with plumbing codes and to protect the integrity of the plumbing system. Discharging water at this temperature or below minimizes the risk of thermal shock to the sewer system and protects the treatment facilities from potential damage caused by excessively hot discharges. This temperature threshold is also important for preventing scalding hazards for individuals who may come into contact with the discharge water, particularly in areas where plumbing lines are exposed to foot traffic or maintenance activities. Additionally, cooling waste to this temperature helps in maintaining the ecological balance of wastewater treatment facilities, as significantly warmer water can disrupt biological processes essential for treating sewage.
