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's website under City Documents. A member of the Wastewater Department staff inspects grease traps/interceptors on a quarterly basis to make sure they are properly maintained. Questions regarding grease traps/interceptors may be directed to wastewater staff at 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.

Wastewater Collection System (sewer mains)
In order to reduce the occurrence of spills and overflows of untreated sewerage, the wastewater division is initiating a cleaning and inspection program of sewer mains. The program consists of cleaning approximately 150,000 feet of sewer lines on an annual basis and inspecting the cleaned lines using a small TV camera.
Prior to connection to the City sewer system, a person must submit an application for connection to the City sewer system. The application is submitted with a $30.00 payment and a site plan.
