(1) Calls for change in the field of water environment infrastructure. In the United States, for example, the cumulative investment needs from 2020 to 2029 in the water system investment gap is expected to be as high as 434 billion U.S. dollars, the U.S. three major water industry associations set up a working group for the future of the water industry development challenges, calls for change, from the promotion of technological innovation, amendments to the environmental protection laws and regulations, the development of action roadmaps and other aspects of the proposal, and ultimately submitted the relevant bill. And China is facing the same problem.

(2) In China, water technology as a whole lags behind the West in this round of technological development. From the point of view of human history, sewage treatment in 1914 activated sludge was born as a symbol, but now only a hundred years of history, through the pollution control, sustainable development and is still in the unknown future of the new water three stages. Sustainable development stage, from the point of view of carbon emissions, resource recovery and material cycle, the international community has completed the deployment of technology, into a series of new technologies to implement the stage of completion of the industrialization of the strategic layout; and our country in this stage and lagged behind five to ten years, and due to the existence of sewage systematic deficiencies in greenhouse gas reduction, resource recovery and other aspects of the gap continues to widen, and gradually moving farther and farther away.

(3) Full confidence in China's exploration of new water services in the future. As a leading enterprise in the industry, Beikong Water has long carried out the exploration of future water services, advocated this action plan for future new water services, and the Beijing-Tianjin-Hebei Innovation Center has jointly established a research center for future new water services, determined the research direction and principles of future new water services and the working mechanism, and explored the form of enterprise participation. Future New Water should be an open form of organization, and more enterprises and institutions are welcome to participate in this plan.

(4) China is facing a strategic turning period in urban water environment management, which is manifested in five major shifts from point source to surface source, the change of main control pollutants, the change from pipe outlet to cross-section water quality, the change from reactive management to proactive pursuits, and the change from urban pollution control to rural water pollution, and at the same time, we are facing a number of challenges and dilemmas. In response to these issues, the opportunities and paths of ecological civilization development model, nitrogen recycling and utilization, upstream concentration concept and other aspects of industrial breakthroughs such as heating pipe networks and building energy consumption are proposed.
