What is a Grease Interceptor?

A grease interceptor (also known as grease trap, grease recovery device, grease capsule, and grease converter) is a control device that is designed to collect and intercept FOG and food waste from wastewater discharged from Food Service Establishments, until they can be removed and disposed by waste hauling. It is typically a large concrete box with two or three compartments and is usually installed underground outside Food Service Establishments.

Installation Consideration

  • Install the grease interceptor as close as practical to the fixture(s) being served.
  • The grease interceptor should be located in an accessible area such that cleaning and maintenance can be easily performed
  • Plumbing containing discharges from food grinders, dishwashers, and wastes from toilets, urinals, wash basins, and other fixtures containing fecal materials should bypass the grease interceptor.
  • A properly sized and designed grease interceptor may not work efficiently if it is installed incorrectly.
  • The cost of installation will vary depending on the site. Cost factors include the size of the device, space, grade, proximity to a sewer line, and above-ground or in-ground installation.
