Importance of Cleaning Grease Traps

Importance of Cleaning Grease Traps

Routine cleaning and inspection of your commercial kitchen grease trap is crucial in preventing major problems with your sewer system. Everything removed from the grease traps needs to be appropriately disposed of in an ecologically friendly way.

Just as if you were home, you would not dispose of bacon grease down your kitchen sink. The oily waste collected by the grease trap interceptors is mostly fat from dishwashers, sinks and kitchen equipment, and is not safe to dispose of using basic procedures. The fat does not decompose easily, and with Maine weather it congeals quickly in cold weather causing back-up.  Because restaurants have greater capacity and quantities of grease waste than your home, cleaning is required more often.

There are numerous possible hazards that can occur if a kitchens restaurant equipment is not properly serviced.  Grease trap interceptors/traps do exactly as described, they are specifically designed to trap grease to prevent it from draining into public waste systems or septic tanks, where it can clog the lines and cause all kinds of damage in the sewer system.  Not only does grease clog your pipes but it flows down stream to the treatment plants costing tax payers thousands of dollars a year to treat and dispose of the grease properly.
