Commercial Inspection and F.O.G. Program

T​he goal of the Commercial Inspection Program is to ensure the integrity and capacity of the sanitary sewer collection system, while providing for the safety of the public and  City workers. Inspection of commercial users helps to verify adequate pretreatment device maintenance and helps identify those responsible for interference or problems experienced in the collection system or at wastewater treatment plants.

Fats, Oils, and Grease (FOG)

The City of Phoenix's Commercial Inspection section is an active participant in the multi-city Fats, Oils, and Grease (FOG) Group activities. The coalition is comprised of municipal pretreatment agencies, public and private sewer districts, nonhazardous liquid waste haulers, treatment facilities, and manufacturers of treatment devices, Maricopa County, and the State of Arizona Pretreatment Coordinator.

The goal of the Arizona FOG (AZFOG) Group is to reduce the amount of fats, oils, and grease that enter the sanitary sewer system(s). Each member deals with specific sanitary sewer regulations which are in place to control discharges generated from commercial food establishments (CFE) and residential sources.

A Separate Arizona FOG Group Web Site has been created with more detailed Information.
