Heavy rain transparent drainage system prosperous market opened new continent

On the evening of July 26, the Beijing Flood Control and Drought Relief Headquarters held a press conference to show that 77 people were killed during the July 21 rainstorm in Beijing. The number of deaths was 46. A heavy rain washed away the dust over the city and the quality of the city’s construction was transparent. In the heavy rain, the construction of the drainage system attracted widespread attention. Heavy rain sounded the alarm for the safety of urban sewage. How is the development of the drainage system market? Can we learn from foreign excellent cases?

First, China's urban construction is heavy. In recent years, China has experienced frequent recurrences of extreme weather events. The frequency and scope of heavy rainstorms have shown an increasing trend. In the past 10 years, there have been more than 7 years of heavy rain days over the years. The increasing frequency of natural disasters and strong pressure from public opinion has forced the government to accelerate the construction of supporting cities. The Beijing torrential rain will force the government to formulate more active construction policies. The pace of development will far exceed the planning, and relevant sections such as pipelines, water and municipal facilities, sewage treatment, and geographic information systems will benefit.

The principle of urban drainage is dredging through the nearest river channel. In recent years, major cities have experienced internal disasters. The causes of rainstorm in Beijing are diverse, but they are representative: drainage design and construction are backward, equipment is aging, there are many overpasses, and the main design is under-bridges. The design of Beijing Pipeline Network is mainly based on drought resistance, with few dredging rivers, and the density of drainage pipe network is less than the national average; the urban development is fast, and the emphasis on ground construction exceeds that of the underground. The density of urban pipe network in our country is far lower than that of the developed countries in the world. The imbalance in regional construction worsens the emergency response capacity of the drainage system in arid cities in northern China. We believe that the importance of urban water conservancy construction has always been ignored by the market. The Beijing storm time will urge the government to accelerate urban water conservancy construction. Due to the frequent occurrence of disasters and the long-term nature of the construction, we believe that the relevant sector will continue to benefit in the long term.

At present, China's urban drainage system is underdeveloped. Beijing is not a special case. Many cities across the country have taken you to see the sea after experiencing heavy rain, becoming the most common ridicule. In the process of our urbanization, we attach importance to the planning and construction of the city's appearance, and we do not attach importance to the construction of supporting facilities such as underground drainage. It is also considered to be the wrong idea of ​​“requiring face, don’t care”. Urban drainage system is the most unfinished cornucopia. The state may wish to attach importance to the role of private capital and formulate reasonable policies to make urban drainage systems an important step for private capital to enter urban infrastructure.

Second, four trillion 2.0 Why not invest in urban drainage system Currently, the market is expected to introduce a stable growth plan. Whether or not a 2.0 trillion version of the market should be introduced has a lot of controversy. Qu Hongbin, chief economist of HSBC Greater China, believes that comprehensive analysis of labor productivity growth, labor force changes and other factors, China's potential growth rate during the 12th five-year period is 9%-9.5%. In view of the above, the 7.8% economic growth in the first half of the year has already fallen below this average growth target. According to factors such as income and employment of Chinese residents, the Chinese economy still needs a relatively rapid growth during the 12th Five-Year Plan period.

However, this kind of economic growth rate should be healthy. It is not an environment-for-GDP development model. Increasing the investment in urban drainage systems is different from the previous investment stimulus plan because cities with underdeveloped drainage systems urgently need to improve drainage systems. The torrential rains caused 77 deaths. This has caused Beijing to lose its reputation as an international metropolis. While strengthening the construction of urban drainage systems, the Beijing Municipal Government should also draw on Hong Kong to formulate the “City Flood Prevention Act”, which covers the prevention of urban internal disasters. Planning and government responsibilities and other aspects related to urban flood protection.

When storms struck, various departments were linked in an orderly manner, coordinating disasters at the first time, and minimizing people’s lives and property losses. This will also satisfy our citizens and thus better trust our government. Judging from various economic indicators, one of the important reasons for the sustained slowdown in China’s economy is the lack of effective market demand, which has led to a cooler situation in the real economy. Therefore, the author suggests that if the country introduces a new round of investment stimulus plans, then the urban drainage system should be included in the key targets.

Third, the urban drainage system will be a new continent for market development In recent years, major cities in China have frequently experienced internal disasters. People have bantered the "plan to visit the sea" to the city's planning and construction, especially the Lizi project has brought a warning. There is no doubt that the failure to attach great importance to these hidden projects of the urban drainage network is the result of a number of cities in the deadly aftermath of the storm. Therefore, the infrastructure construction including the urban drainage system in the future will surely become the focus of concern.

The development of urbanization in China reached the time of reflection. The 30 years of reform and opening up were the 30 years of rapid economic development in China. However, during the 30 years of rapid development, it was also the fastest 30 years of urbanization in China, especially in recent years. In rural construction, our country has changed from urbanization to urbanization. Whether it is the development of urbanization or the urbanization of new rural construction, the author believes that it should not be “emphasizing the ground and light underground”. The sewer is the conscience of the city.

For many years, China’s urbanization has always had the problem of “rather ground and light underground”. The consequence of despising the underground drainage system is that a heavy rain can become a major disaster for us. The economy is damaged and our lives are in dire straits... The improvement of the urban drainage system is a matter of no delay. Now that the global economy is sluggish, and economic downturn pressure remains high, we do not need to invest in roads, railways, and high-speed rails to stimulate the economy and boost domestic demand. The national investment plan may be tilted toward infrastructure such as the drainage system, for stable growth. The "underground" investment has the same effect.

Heavy rain has become an important criterion for testing the process of urbanization in China. In China's urban drainage system, in addition to Ganzhou in Jiangxi (built in the Song Dynasty) and Qingdao (built by Germans 100 years ago), the drainage system in other cities needs improvement. To strengthen the construction of urban drainage systems, it is not necessary to study abroad to study. It is sufficient to look at the sewers in Qingdao and Zhangzhou. Therefore, the author suggests that if the country introduces a new round of investment stimulus plan, then the urban drainage system should be included in the key targets.

Urban drainage system market to be developed At present, many urban drainage systems in China are very unreasonable. Beijing is not a special case. Many cities across the country have taken you to see the sea after experiencing heavy rain, becoming the most common ridicule. In the process of urbanization, we attach importance to the planning and construction of the city's appearance, and do not attach importance to the construction of underground drainage and other supporting facilities. We are also considered to be face-saving and not to have the wrong ideas.

Urban drainage is a complex three-dimensional system. A complete drainage system includes pipeline construction, supporting construction (including drainage outlets, pumping stations and river channels to widen dredging and reinforcement, etc.), sewage treatment, pre-disaster warning, and post-disaster processing. According to the “12th Five-Year Plan for Urban Wastewater Treatment and Recycling Facilities Construction,” the annual average growth rate of China's sewage pipe network reached 14% by 2015. According to future development requirements, rain and sewage diversion will replace the confluence system, together with the elimination of old pipelines, the new construction demand will far exceed the planning.

Conclusion:

The “Urban Drainage and Sewage Disposal Regulations” is about to be introduced. The urban drainage system is an undeveloped cornucopia. The construction of a city drainage system and the construction of a subway project, with a total investment of 100 million yuan, will drive GDP growth by 263 million yuan (including: iron and steel, coal, cement, pump valves, wires, clothing, fasteners, and other electromechanical industries). Since reform and opening up 30 years ago, China’s private enterprises have developed rapidly and have earned a lot of foreign exchange. They have made a lot of contributions to China’s economic development. Today, large Chinese companies and big groups have developed abroad. Private capital should enter urban infrastructure and urban sewers for our country’s The contribution of the urban drainage system to do more is also an important step for the development of private enterprises.
