When I'm often asked when grease interceptors should be serviced, I wonder whether those who are asking have bigger concerns -- notably that increasing the pumping frequency of grease separators does not eliminate high FOG effluent numbers.
Today and in the future, the link between customer and vendor will be absolutely vital. Why? Consider the struggle restaurant operators are having with hiring. It’s not just food service, either. All service industries are having trouble with staffing, including plumbing.
Restaurant businesses need vendors to step up with the kind of help we provide. We all know optimal service begins with having good customer information to begin with. That’s why we just launched a campaign to compel more customers to register their devices with us.
In the late 1980s, The Narragansett Bay Commission (NBC) provided a great example of how to maximize control when it carried out one of the most effective Pretreatment programs I've seen in my career. It had to implement an audacious pretreatment program to reduce downstream wastewater treatment plant loadings sufficient to meet the EPA’s first Marine Estuary Guidelines. The NBC was in a tough spot.
Pretreatment’s Three-Legged Stool
A simple, yet effective way to explain on-site pretreatment is to use a three-legged stool analogy.
A three-legged stool works only when all three legs are the same length and angle and have the same strong attachment to the stool seat. If any leg is shorter, at a different angle, or loosely connected to the seat, the stool is unstable.
The same is true for onsite pretreatment. A food service establishment (FSE) may have
Leg 1: The right grease separator and
Leg 2: Good servicing (pumping frequency and quality)
But if it has poor internal management practices (Leg 3), the FSE will send higher than allowed waste into the sewer system.
Likewise, a site skimping on pumping (Leg 2) will handicap its proper technology (Leg 1) and best management practices (Leg 3). Upcoming blog posts delve into practical information for each of these legs. We begin with Best Management Practices 101.
