Grease traps are receptacles designed to collect and retain or remove grease and fatty substances from wastewater normally resulting from the commercial handling, preparation, cooking, or dispensing of food. They are required on private commercial sewers which discharge directly or indirectly to the City's wastewater system and into which significant amounts of grease may be discharged.
Negative Impact Reduction
With the large number of restaurants and eateries operating in the City and the subsequent discharge of fats, oils, and grease (FOG) into the sewer flow, sewer pipe capacity is substantially reduced.
The division has implemented several procedures and practices to either reduce the amount of grease entering the lines or remediate the negative impact grease has on sewer transport. These procedures are as follows:
- Proactive approach to grease trap inspections and requirements
- Improved communication with restaurant owners
- Implementation of automated bacteria injection devices
Restaurant establishments must install grease traps in order to comply with the necessary regulations for acquiring and maintaining a common victualer’s license (PDF).
