The District would like to remind you to can the cooking grease this holiday season. Cooking, especially during the holidays, can leave gallons of unwanted oil and grease to clean up.
Used cooking oil can congeal, resulting in clogs and blockages in homes as well as in the collection system. Pipes blocked by grease is an increasing cause of sewer overflows. Too often, grease is washed into the plumbing system, usually through the kitchen sink. Grease sticks to the insides of sewer pipes (both on your property and in the streets). Over time, grease can build up and block the entire pipe.
Deep-fryer oil should never be poured on the ground or down a storm drain, which could pollute waterways and clog the storm pipe.
