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.

Frequently asked questions:

-How often does my grease trap have to be inspected?

I am a first time homeowner and needed a new sewer line installed, heart stopping when I had no knowledge of such things. I called northeast sewer everyday for a week with questions and concerns. They televised my line and showed me exactly where the break was (pretty amazing) I could see it on the screen!! Fixed it in one day!!

– Teran

Justin and Kelly are the owners, and they could not have been better to work with. I had a 120 year old BRICK (yes, brick) sewer line collapse and they diagnosed the problem, involved the city and fixed it for less than I was expecting to pay. I learned that they own and operate their own excavating equipment which means jobs are done more quickly and less expensively than others. I am a raving fan, and have already referred them out.
