Implementing A Grease Trap/Interceptor Inspection Program

Presented by:

Tammi Gall, Project Manager

Why a FOG Control Program?

• To properly manage the Fats, Oils and Greases (FOG) in sewage that impacts our collection systems and treatment processes. The reason for this is these materials harden and plug sewer line. Even small amounts of grease and cooking oil will accumulate in the sewers. As the materials collect they slowly build bridge-like structures in pipes. This causes backups and interrupts the flow of sanitary waste streams in the sewers. All the sanitary sewers flow through local wastewater treatment plant which is not designed to remove fuel products, grease or cooking oils, more commonly known as FOG.

FOG Control

FOG Control

How do we control the FOG?

• Local Sewer Use Ordinance

• Make sure there is enforcement language in the ordinance

• By referencing the Plumbing Code (2015) for actions that sewer customers have to take for your abatement program

• Section 802.1.8 and Section 1003 et el

FOG Control

• The 2015 MI Plumbing Code, Section 1003 has specific requirements for Interceptors and Separators.

• They have to be sized according to flows and be able to hold the pounds of solids as prescribed in the Code.

The key to success of the Abatement Program?

• The units to be cleaned periodically!

• Cleaning may be daily, weekly, monthly, quarterly depending on the time/accumulation cycle.

• Under the sink-weekly

• Interceptor-quarterly

FOG Control

• Why a FOG Abatement Program?

• To maintain the efficiencies of the Wastewater Collection/Pumping/Treatment Systems.

FOG Control

How do we accomplish this?

• Inspections and management, just like the CCC Program

• Many Utilities now use the same personnel to perform the CCC inspections as well as the FOG inspections.

BEST PRACTICES

• The best way to prevent sewer lines from becoming plugged with sewer grease or cooking oils is to remove these materials before they enter the sanitary sewer. This is accomplished by having an active “Best Practices”

• This includes scraping plates or pans removing grease, or grease-like materials and disposing the materials in the garbage.

• Routine cleaning of grease traps and interceptors are a must! These units may need cleaning many times per day or week to prevent downstream problems.

• Do not relay on “bacteria or enzyme products” they do not remove grease or keep grease from forming ridges in sewers..

FOG ControlPumping/Treatment Plant Significance:

FOG Program Management

• Due to today’s limited number of personnel and financial constraints, Utilities are now using the same inspectors for each program. Kind of a “one stop, one person” inspection/enforcement program.

• Today we use software to track the inspections and tests, generate letters and store pictures for documentation/litigation purposes.

• There are many software programs such as BPMS, Tokay, XC2 etc..
