Fats, Oils & Grease (FOG) Program
The City of Lake Oswego has partnered with the City of Portland to implement a Fats, Oils and Grease (FOG) Program in Lake Oswego. Wastewater discharges from commercial food service establishments are the main sources of FOG and other food waste in the public sewer system.
What is the FOG Program?
FOG discharges into the sewer system can build up in pipes and negatively affect the wastewater treatment process. FOG buildup in sewer pipes can cause blockages, resulting in sewage overflows that can damage property, harm the environment, threaten public health, and lead to penalties. In Lake Oswego, the City of Lake Oswego owns and operates the wastewater collection system, and the City of Portland owns and operates the wastewater treatment plant. Both cities have the responsibility to ensure that FOG is not harming our infrastructure.
Examples of FOG:
- Cooking oil
- Meats and fish fats
- Gravy and soups
- Butter, shortening, lard, and margarine
- Milk, cream, sour cream, and mayonnaise
- Sauces and food scraps
