Commercial Pretreatment

Commercial Pretreatment


As of February 21, 2023, the Commercial Pretreatment program will transition to a secure, web-based portal that enables customers to apply for a Fats, Oils, and Grease (F.O.G.) commercial pre-treatment permit.

The new portal, which will be accessible 24 hours a day, will also allow customers to track their application, submit payments and necessary documents, and correspond with the Commercial Pretreatment Division.

Additionally, customers will be able to make changes to their account, view and manage multiple locations, and more. Click here to access the portal.

Online registration and participation will be mandatory for all customers who wish to obtain and/or maintain a permit.  Customers who are not registered will not be able to obtain or renew a permit, which is required for facility operations.  Support is provided to assist with online registration if needed. For more information or to submit questions, please contact Commercial Pretreatment at  

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”.
