Grease control
City Code Chapter 13 – Wastewater, Article 13.40 Pretreatment Requirements  

The City Code contains provisions in Chapter 13.40 aimed at controlling the discharge of grease, oil and fat from food preparation, food handling facilities and other grease and oil generators into our wastewater collection system (sewer mains). These provisions include a requirement for permits to discharge from grease traps and interceptors. Chapter 13 of the wastewater code is located on the city website under city documents.  Wastewater Department staff members inspect grease traps/interceptors on a quarterly basis to make sure they are properly maintained. Questions? Call 204-2234.

Grease trap and interceptor permit requirements. Owners and operators of food preparation and handling facilities, as well as other facilities utilizing grease traps and/or interceptors, are reminded that a permit is required to discharge to the city sewer system; this is in addition to paying a capacity fee.
