Where does FOG come from?
Even if you don’t deep fry food, FOG still occurs naturally in many foods, which leaves a residue behind on dishware that has been used to handle and prepare food. When dishware is washed with hot water and detergents the FOG residue becomes liquefied and is mixed with the dishwater. The mixed or emulsified FOG is then discharged with wastewater into your plumbing wastewater drain lines and, ultimately, to the City of Murfreesboro’s wastewater collection system by Food Service Establishments (FSE’s) such as restaurants, but is also discharged by other commercial FOG generators and residential dwellings, as well.
