Chapu Water Governance Project of Putuo District, Shanghai Dong Rui chief of planning section, Shanghai Putuo environmental protection bureau 2018.06

01 Water Pollution Prevention Background in Recent Years of China C R iver hina Suzhou River Country At present, the important fourth project In 2015, the State Council issued of water Suzhou River-Comprehensive Control will Action Plan for Water Pollution Control ; in be conducted, planning that the water quality in 2016, River System is conducted. 2020 will reach the V standard of the surface water. S P utuo hanghai Putuo District Shanghai Start the whole- covered “One River, Until 2020, the water quality of the One Strategy”. Through the effort of two whole city will be effectively improved, years, among the 55 rivers, there are 30 basically eliminating the water body rivers of the qualified rivers increased section which loses the using function from eight rivers. (worse than V class)

02 Riverway Overview Xinchapu Riverway overview ： The whole length is 9.5km, Zhongchapu running through Baoshan, 新 Jiading and Putuo, among Riverway overview ： The total length is which the length in Putuo 5.92km, among which the length in District is 3.84km. Putuo District is 2.96km and the rest 中 槎 ones are all in Jiading District. 槎 浦 Water quallity oveview ： The Water quality overview ： The water 浦 water quality standard in 2015 is quality standard in 2015 is bad V class, and the bad V class, and the average average annual ammonia-nitrogen annual ammonia-nitrogen concentration is 5.11 ㎎ /L. concentration is 5.55 ㎎ /L. The two Chapu rivers are branches of the main river --Suzhou River, which is one of the longest and the most important rivers at Shanghai.
