The minimum rated flow capacity for a grease trap is ______________________.

The minimum rated flow capacity for a grease trap is established to ensure proper functioning and compliance with plumbing codes designed to manage wastewater containing fats, oils, and grease (FOG). A grease trap with a rated flow capacity of 20 gallons per minute (gpm) is generally recognized in various plumbing codes, including the Omaha Plumbing Code, as sufficient for typical commercial kitchen applications. This capacity allows for effective separation of grease from wastewater, reducing the likelihood of blockages in the plumbing system and subsequent environmental impacts.

A grease trap that meets or exceeds this minimum flow capacity can adequately handle the volume of wastewater generated during peak usage times, which is critical for maintaining sanitary conditions and preventing plumbing issues. It's essential to adhere to this standard to ensure that the grease trap performs its function efficiently and complies with local regulations aimed at protecting the municipal sewer system.
