Cooking fats, oil and grease are some of the primary causes of sewer systems backups and overflows. Grease and oil congeal when mixed with water, sticking to the walls of the pipe and building up over time. Eventually, the solidified oil and grease will clog the pipe, causing problems in your residence and/or at the treatment plant.Additionally, cooking fats, oil and grease are some of the most difficult substances to break down, which can slow down the treatment process. This prevents us from meeting our goal of making all public waters suitable for wildlife and public use, so please help us to help you by keeping cooking fats, oil and grease out of the collection system.
