Commercial Pretreatment


Program monitors and inspects pretreatment systems of commercial facilities, called commercial waste generators, to prohibit the discharge of fats, oil and grease into County’s sanitary sewer system. Commercial waste generators are restaurants, schools, churches, hotels, institution kitchens, and other food service establishments, as well as car maintenance, automobile dealers and car/truck wash facilities.

All commercial waste generators with a grease trap, oil separator and sand trap that discharge fats, oil and grease into County’s sanitary sewer system are required to have a permit for their pretreatment system called “Commercial Waste Discharge Permit”. 


Fulton County Sewer Use Ordinance, Section 82-251
