The sewage treatment plant in Xichong County is not operating, so the sewage is discharged directly into the river.
Xichong County Sewage Treatment Plant Director Bai Ping explained that the main reason was that on the 11th, a main power supply line in the county sewage treatment plant was burned due to overload, causing sewage to be pumped to the sewage treatment plant. The water pump failed to operate, and sewage overflowed through the manual inspection well and flowed directly into the Hongxi River. After inspection, it was found that the burned power supply line was a special power supply line that was only sold in Nanchong. Bai Ping said that after the accident, Xichong County Sewage Treatment Plant quickly arranged for staff to go to Nanchong to purchase this special power supply line material. The staff visited four or five stores before purchasing this material in Jialing District. After taking Xichong back, the Xichong County Sewage Treatment Plant quickly arranged for personnel to replace the burned power supply lines. It was not until 5:50 pm on the 11th that the power supply line repairs were completed and the Xichong County Sewage Treatment Plant resumed operation. Afterwards, it was calculated that within 7 hours of the sewage treatment plant failure, a total of 6,000 to 7,000 cubic meters of sewage directly flowed into the Hongxi River.
