A grease interceptor is required for establishments serving food when the fixture count exceeds how many units?

A grease interceptor is an essential component in plumbing systems, particularly in establishments serving food, because it helps to mitigate the buildup of fats, oils, and grease (FOG) that can clog sewer lines and cause costly environmental issues. The requirement for a grease interceptor is typically based on the number of plumbing fixture units in the establishment.

In the context of Omaha Plumbing Code, the threshold at which a grease interceptor becomes mandatory is when the fixture count exceeds 20 units. This is based on the consideration that a higher number of fixtures typically correlates with increased food preparation and washing activities that produce FOG. Therefore, when an establishment surpasses this count, it raises the likelihood that adequate drainage and sanitation measures, such as a grease interceptor, are necessary to manage waste effectively.

By installing grease interceptors in establishments that exceed this fixture count, it helps to ensure compliance with local codes, reducing the risk of plumbing back-ups and environmental contamination while promoting a cleaner, more efficient waste management process.
