Grease Trap Cleaning Vs. Grease Interceptor Cleaning

May 26, 2020 Sewer Line 0

What is the purpose of grease traps and grease interceptors?

Grease traps and grease interceptors perform similar functions—i.e., preventing fats, oils, and grease (FOG) from leaving a kitchen facility and clogging sanitary sewer lines. These FOG compounds are byproducts of cooking that stem from the usual suspect food materials such as meat and dairy products. When disposed of down a drain, they can stick to the inside of sewer lines causing buildups, blockages, and other serious problems.

What is a grease trap?

A grease trap is a small FOG removal unit designed for use in kitchen applications where the flow of water and amount of oil and grease produced is low. It is typically installed beneath the sink inside the kitchen facility.

What is a grease interceptor?

A grease interceptor is a large FOG removal unit. It is generally installed beneath large-scale kitchen facilities that produce a large amount of grease and have higher flow rates and pressures.

How should restaurant owners maintain a grease trap or grease interceptor?

To maintain an efficient grease trap (or anything mechanical really) consistent maintenance is the key. Though some municipalities dictate otherwise, traditional, underground grease traps and grease interceptors should be pumped out every three months or when they reach 25 percent of the grease trap or grease interceptor depth, or whichever comes first. Typically, cleaning frequencies for grease traps and grease interceptors may be in the range of daily to weekly depending on the the restaurant.

What enforcement action(s) could potentially occur if the regulations of the FOG Ordinance are not met by my restaurant or food service establishment?

Enforcement actions could include, but are not limited to, a notice of violation without fine; notice of violation with fines of $100 or $200; civil penalties; submission of a compliance plan; installation of a properly sized, exterior grease interceptor; and clean-up costs for blockages and sanitary sewer overflows.
