The 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 the City's workers. Inspection of commercial users helps to verify adequate pretreatment device maintenance, supports enforcement action, and helps identify those responsible for interference or problems experienced in the collection system or at wastewater treatment plants.
Routine/Educational Commercial Inspections
Routine commercial inspections are performed periodically to confirm the proper operation, maintenance, and capacity of pretreatment devices. In addition, the purpose of these inspections is to receive information from commercial users and to provide advice and leave educational material, thus maintaining a cooperative as well as a regulatory presence within the regulated community.
Commercial Complaint Inspections
Commercial Complaint Inspections are conducted in response to notification from the public, either directly or through outside agencies, and from other City departments. An inspection is performed when the Environmental Services Division receives a complaint concerning potentially harmful discharges to the sewerage system.
In the event of a blockage or a discharge violating the General User Requirements of the Phoenix City Code, facilities discharging to the affected sewer are inspected to determine if they may have caused or contributed to the incident. Pretreatment devices are checked and waste management practices are evaluated. If appropriate, Notices of Violation are issued at the time of inspection, which usually require prompt remedial action. Failure to take required corrective action as directed can result in termination of water and sewer service.
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.
