Ejector basins should not retain waste discharge for a period exceeding how long?

• A. 6 hours
• B. 12 hours
• C. 24 hours
• D. 48 hours

Answer: (B)

Ejector basins are designed for the purpose of collecting and removing wastewater, particularly when it's necessary to lift sewage to a higher elevation for proper drainage. Keeping waste discharge in an ejector basin for an extended period can lead to several issues, including unpleasant odors, the growth of bacteria, and other health hazards associated with stagnation. The recommended maximum retention time of 12 hours is a standard established to ensure that the waste does not remain stagnant long enough to create any negative conditions. Retaining wastewater for longer can significantly increase the risk of these issues and compromise the effectiveness of the plumbing system. Thus, the 12-hour guideline is set to ensure the system operates efficiently and maintains sanitary conditions. Retention times longer than the recommended threshold could lead to violations of health and safety codes, which aim to protect both public health and the integrity of the plumbing systems.
