Laurel restaurants required to have grease traps

Posted on: September 23, 2017

The Laurel City Council has passed a new ordinance requiring new restaurant owners to purchase grease traps. Mayor Johnny Magee said kitchen grease is clogging up the city’s sewer system and costing the city a lot of money to fix it.

Grease traps – also known as grease interceptors – are located between restaurant drain lines and sanitary sewer lines and help to separate and collect fats, oils, and greases from used water. These traps help to prevent unwanted materials from entering the municipal sewer system . Grease, the industry term for animal fats and vegetable oils, is 10 to 15 percent less dense than water. Grease also won’t mix with water. As a result, fats, oils, and grease float on top of water.

When kitchen wastewater flows through a grease interceptor, the grease and oils rise to the surface inside the trap and are trapped using a system of baffles. The captured grease and oils fill the trap from the top down, displacing “clean” water out of the bottom of the trap and into sewer line.
Peer into a grease trap and you’ll see a mat of grease. When this mat of grease gets deep enough, the trap must be cleaned out.
