Grease Traps and Tanks
Most newer restaurants have large in-ground grease traps or interceptors that work like a septic tank.
These interceptors catch/retain the grease and prevent it from entering the sanitary sewer system where it can cause blockage problems.
Routine cleaning to remove the grease and waste water is necessary to keep the
grease out of the sewer or from causing a backup in the building.
Grease traps need to be large enough for the incoming water to cool in the tank.
This allows the grease to separate and become a semi-solid in the tank.
