What is the minimum capacity of a grease interceptor?

The minimum capacity of a grease interceptor is significant for ensuring that it effectively separates grease and other materials from wastewater, preventing blockages and maintaining sanitary conditions in drainage systems. The standard minimum capacity for grease interceptors is typically 750 gallons. This size is widely accepted in various plumbing codes and regulations, as it allows for adequate retention time of the wastewater, which is crucial for the efficient separation of grease. A properly sized grease interceptor helps avoid costly plumbing issues and is essential for compliance with local health and safety standards.

Other capacities, such as 500 gallons, may be too small to handle typical kitchen waste loads, while larger capacities like 1000 and 1500 gallons exceed the minimum requirements and may be more appropriate for larger facilities but are not the baseline standard. Thus, the correct minimum capacity aligns with regulatory guidelines and practical needs for commercial kitchen operations.
