Can unused cooking oil be poured directly into the sewer? What should I do?

Don't pour unused cooking oil directly into the sewer, because oil-water separation is the most difficult and energy-consuming process in sewage treatment. It is suggested to pour the gutter oil into a waterproof garbage box and then put it into a garbage bag.

Don't pour cooking oil and vegetable residues into the sewer. Edible oil and vegetable residues are one of the reasons that lead to sewer blockage and hinder water treatment. Vegetable residues are recycled as domestic garbage. Don't pour directly into the sewer.

Case:

At the Xinfu River in Qinhuai District, a hotel poured the swill oil directly into the roadside sewer, only 20 meters away from the Inner Qinhuai River. On the afternoon of March 15, the hotel staff was caught by the law enforcement officers of Qinhuai District Urban Management while pouring swill oil and fined.

After several days of squatting, urban management law enforcement officers finally found something at about 3: 30 pm on March 15. A light truck, loaded with seven or eight large plastic buckets, drove to a place not far from the hotel and stopped. After the driver got off the bus, he first poured the restaurant kitchen waste into a large plastic bucket, then separated the oil and water floating on the surface into another small bucket, and then carried the small bucket to the back of the truck.

When the law enforcement officers caught up with him, it turned out that the driver was using the car as a cover and was secretly pouring swill oil into the sewer. On-site law enforcement officers said that the sewage outlet of the dumped swill oil is only about 20 meters away from the Inner Qinhuai River, and these swill oils are likely to be discharged into the Inner Qinhuai River. Qinhuai District Urban Management Law Enforcement Department imposed a fine of 5,000 yuan on the hotel and a fine of 1 1,000 yuan on the driver Zhang according to relevant regulations.

People's network-swill fat poured into the sewer was fined 5000 yuan.
