Enviro-Tech Pumping Grease FAQ
What is FOG?
FOG is an acronym for Fats, Oil and Grease. FOG is a byproduct of cooking and meat cutting, and includes oils, animal fats and vegetable fats .
What do FOG investigators look for?
FOG Investigators will inspect the sewer system for grease accumulation. They will verify that the food service establishment is implementing Best Management Practices for controlling FOG. The grease collection system will be inspected to verify that it is adequately sized for the connected fixtures, that it is being properly maintained, and that it is in operating condition. If no grease collection system is present, the food service establishment may be required to install one.
Why is FOG a problem?
FOG has a negative impact on wastewater collection and treatment systems. Most wastewater blockages can be traced to FOG. Blockages in the wastewater collection system can cause sewage spills, manhole overflows, and even sewage backups in homes and businesses.
Who produces FOG?
Generally, FOG is produced by anyone who deals with food preparation, including many commercial sources as well as residential sources.
What's the difference between oil and grease?
While oil and grease are almost always tied together, they represent very different substances. Oil is a liquid left over from frying and grease is a white solid residue left in the pan after frying items such as bacon.
Where does FOG come from?
Oils and grease are used in the food preparation process as ingredients or non-stick remedies. The FOG ends up on cookware, dishware, kitchen equipment and even floors and floor-mats, all of which must be washed.
What is a grease interceptor?
A grease interceptor is typically a concrete vault with a capacity of 750 to 1000 gallons. It is built into the wastewater piping and located below ground outside of the FSE building.
What is a grease trap?
A grease trap is a small container built into the wastewater piping a short distance from the grease producing area.
What are the criteria for maintenance and securing my grease trap?
How does a grease interceptor work?
A grease interceptor provides suspended FOG in the wastewater time to congeal and rise to the surface. The interceptor has a minimum of two compartments, and allows water to flow between each compartment while the grease is captured and stored for disposal.
How does a grease trap work?
A grease trap retains wastewater long enough for the grease to congeal and rise to the surface. These small devices need to be cleaned frequently, from daily to weekly, and this duty is performed by Enviro-Tech Pumping.
