Fat, oil & grease (FOG) can be generated from cooking of beef, pork, chicken or anything using cooking oils. The primary FOG producers are restaurants but households can generate FOG by disposing of cooking oils, salad dressings, etc. down their sinks.
By using best practices you can prevent FOG clogging your sewer and help prevent increased sewer rates due to the city waste treatment plant having to spend extra money treating for FOG.
Some best practices are as follows: dry cleanup of spills, recycle cooking oil, and maintain your grease traps by inspecting weekly and having grease traps cleaned or skimmed each month.
