Additional Notes
Omaha adopts the Uniform Plumbing Code (UPC) rather than the IPC, which is notable as Nebraska is one of the states that uses UPC. Article XI of the Omaha City Plumbing Code governs grease interceptor requirements. All FSEs generating FOG must install approved grease interceptors. The city requires that interceptors be accessible for inspection and cleaning. Grease haulers must provide documentation of proper disposal at approved facilities.
Regulations change frequently. Always verify current requirements with your local wastewater authority or plumbing inspector before making compliance decisions. Last updated: March 2026.
