water treatment is in the golden age, and the investment in key projects in key river basins is about 700 billion yuan.
in 2018, president xi reiterated at the eighth national conference on environment and ecology that the plan of action for water pollution prevention and control should be implemented in depth. the next 5-10 years will be a golden period for water management. the focus of water management is on water pollution control facilities and water environment management. during the 13th five-year plan period, it was conservatively estimated that about 40 million tons/day of urban sewage treatment facilities needed to be renovated and 50 million tons/day of new capacity needed to be built. according to the black and odorous water monitoring platform of the ministry of environmental protection, 790 black and odorous water bodies are in the treatment stage, and 190 black and odorous water bodies are still in the formulation of treatment programs. the total length of 2100 black and foul water bodies in the whole country is about 7057 km, and the length of a single black odor water body is about 3.36 km. it can be deduced that the part of the governance has not yet been completed about 2000 km. according to the assumption that the unit treatment cost of black and odorous water in the industry is about 50 million per kilometer, the total investment is about 100 billion yuan.
in the national development and reform commission's "water pollution prevention and control plan for key watershed (2016-2020)", the investment of backbone projects in key river basins was reckoned, totalling 700 billion yuan. among them, "urban sewage treatment and construction of supporting facilities" in addition to the aforementioned sewage treatment facilities, but also includes sewage pipe network, amounting to about 316 billion yuan. for the purpose of focusing on water environment management in this section, the future market space will be released mainly under the "comprehensive water environment management" project of the national plan, that is, about 270 billion yuan.
the market has confidence in the target of black and odorous water treatment in 2020, and it can be completed in 2018.
the year 2017 is the mid-term assessment year of "ten water articles". the target of black and odorous water treatment is to "basically eliminate black and odorous water bodies in municipalities directly under the central government, provincial capitals and planned single-row urban built-up areas", "the prefecture-level and above urban built-up areas will realize that there are no large areas of floating matter on the river surface, no rubbish on the river banks and no illegal sewage outlets according to the statistics of the monitoring platform data of the ministry of housing and construction, as of may 19, 2008, the completion rate of black and odorous water treatment in provincial cities has reached 98.53%, 604 black and odorous water treatment have been completed, the assessment target of the black and odorous water body in 2017 has been successfully achieved, and the confidence of the market in the target of black and odorous water treatment in 2020 has been enhanced.
hundreds of billions of dollars are invested, and the market space is available. as of mid-may, a total of 2,100 black and odorous waters with a total basin area of 1,463 square kilometers were identified nationwide; 91 water bodies with a total area of 14 square kilometers were in the process of formulating control plans; 264 water bodies under control, totalling 170 square kilometers; 1745 water bodies under control, totalling 1,279 square kilometers, had been completed. under the official caliber, the black and odorous waters of the 87% drainage areas have been completed.
at present, the unfinished length of urban built-up areas above prefecture level in china is estimated to be 1350.48 kilometers. the special action of the ministry of environmental protection and the ministry of housing and construction for the treatment of black and odorous water in 2018 has provided a strong guarantee for the landing of black and odorous water treatment and operation. under the high pressure of environmental protection supervision, it is expected that the governance in the latest years will also be completed. assuming that there are false reports, the completion of the false report project plus the area under treatment, according to the input of 300 million yuan per square kilometer, it is estimated that the amount of investment in the treatment of black and odorous water in 2018 will be more than 100 billion yuan.
