Rivers in the city center are much cleaner than last year, with an enhanced water-quality in 201 river ways thanks to a three-year water-quality improvement campaign.
In July last year, 1,217 meters of slope-protectors were built for Zhongyuan River in Yangpu District, with 33,000 cubic meters of silt cleaned and 15,000 square meters of greenery planted. In order to improve water quality, a pipeline with a diameter of one meter has been buried at the eastern bank of the river to transport clean water.
This year, 3,000 square meters of greenery was built along the river.
By October, more than 230 river ways in the city center will have their bad odors eliminated and become much cleaner. A total of 27 river-cleaning service agencies will be launched in the city center, with 941 cleaners and 12 additional cleaning ships.
