First, the catering industry is the main culprit of sewer grease clogging. Kitchens in the catering industry need to use a lot of hot water to clean kitchenware and cutlery, and over time, a large amount of grease is discharged into the sewers along with the water, which will gradually solidify over time, leading to narrowing and clogging of the sewers.
Secondly, personal bad habits are also one of the causes of sewer clogging. Some people don't categorize the greasy waste when they clean it and pour it directly into the sewer. These greasy wastes will adhere to the inner walls of the pipes and slowly build up, eventually clogging the sewer.
Lastly, aging pipes are also a major cause of sewer grease clogging. Many city sewers have been in use for decades, and a certain amount of dirt has developed on the inner walls of the pipes, leading to deterioration in the smoothness of the pipes, while waste from restaurants and other industries exacerbates the sewer problem.
In summary, the clogging of grease in sewers is the result of many factors*** working together. Therefore, reducing waste discharge, strengthening pipe maintenance and upgrading equipment are all effective measures to solve the problem of grease clogging. In addition, advocating the public to correctly categorize and dispose of waste is also an essential environmental education.
