Under Delaware Regulations Governing a Detailed Plumbing Code (IPC-based), food establishments here must control fats, oils & grease (FOG) with a grease interceptor or trap, and typically register with the local sewer/wastewater authority. Grease interceptors are required for food establishments under Delaware's state plumbing code, with FOG discharge permits from the local sewer authority.
Size the interceptor with our grease-trap sizing calculator, compare units in the grease-trap catalog, and confirm the local FOG permit with Delaware DHSS - Division of Public Health, Office of Food Protection (state-run) (contact above).
