"2022 Shanghai Minsheng Interview" series programs

He revealed

Shanghai is studying the feasibility of time water prices

And public direct drinking water facilities

The future may ...

It is cheaper to use water after 9 pm

No need to take the kettle to run

Shanghai Zheng studied public direct drinking water facilities during the World Expo.

Public direct drinking water facilities are often seen abroad. During the Shanghai World Expo, there was a pilot of direct drinking water in the Expo Park, which was well received. Recently, some public spaces in Luzhou, Zhejiang have also launched direct drinking water facilities.

Shi Jiaming said

Shanghai Water Affairs Department is very concerned about this

Starting research with related water supply companies

"'One River and One River', the citizens like to go very much. The stations along the river and some direct drinking water facilities are installed. When the weather is hot, the people do not have to run with the kettle." Shi Jiaming said that direct drinking water facilities can become improved A starting point for residents.

In addition to exploring direct drinking water facilities in public space, letting the leading water of the households meet the standard of direct drinking water, and it can also greatly enhance the sense of gain of residents. The overall planning of Shanghai City is clear. By 2035, Shanghai's tap water and faucet water can meet the standard of direct drinking water.

Shi Jiaming said that to allow faucet water to drink direct drinking, the key is to cross the secondary water supply facilities. Due to the influence of some old and secondary water supply facilities, some tap water flowing out of the direct drinking standard when the water outlet plant is out of the water. Direct drinking, some residents also purchased water purifiers for this.

While accelerating the transformation of Shanghai Old Water Supply Facilities, Shanghai plans to pilot tap water directly in the Lingang area and five new cities and other regions.

According to reports, most of these areas are newly planned. The design standards for secondary water supply facilities are high. In some areas, referring to the experience of Tokyo, Japan, use stainless steel pipes, and the pipeline is brand new, making the faucet water very close or even equivalent to the tap water factory factory factory factory The state of time.

However, letting faucet water meet the standard of direct drinking water, and a large amount of funds need to be invested. "Now there is a contradiction, high -quality water supply 'quality and quality is not good", which is the same as the charging standards of normal tap water. "Shi Jiaming said that how to improve the enthusiasm of water supply companies, the next step is to study and explore.

Shanghai study time -sharing water price guidance peaks to drain water with water

The weather is hot, and everyone is very concerned about whether the urban water supply capacity can meet the water demand during the peak period, but it is easy to ignore the drainage problem. In fact, this is also a challenge that the city in Shanghai to ensure stable operation.

"The water habits of residents will have a certain impact on the water environment." Shi Jiaming, director of the Shanghai Water Affairs Bureau, said in today's "2022 People's Livelihood Interview" that Shanghai is currently in the flood season. The impact of the peak of water overlay, the displacement volume may still exceed the processing capacity of the sewage plant, resulting in problems such as the lack of water from the sewage plant, the sewage of the sewage directly, and the drainage of drainage in the upstream areas of the drainage system.

"The pressure of flood prevention and Taiwan is still very stressful. We must prevent typhoons, heavy rain, tide positions, and upstream floods 'four meets'." Shi Jiaming said that once a "four meetings" appear, the Shanghai drainage system will face severe challenges. Last year, the typhoon "fireworks" caused a certain degree of stagnant water in the local area of ​​some suburbs of Shanghai.

According to statistics, the peak operation of the sewage system in the central urban area of ​​Shanghai is generally concentrated at 14:00 to 16:00, 16:30 to 17:30, 20:30 to 20:30. Residents' living habits.

"We recommend that residents save water and peak water, which can effectively alleviate the pressure of the sewage system." Shi Jiaming said that water -saving is also a means of pollution control.

In addition, the Shanghai Water Affairs Department also uses accurate scheduling sewage, such as storage tanks, pipeline capacity, and sewage pumping stations to reduce sewage transfer during peaks, increase transportation during the trough, and reduce the effects of sewage volume on the stable operation of sewage plants on the stable operation of the sewage plant Essence Some sewage factories are also constantly optimizing the process, and under the premise of ensuring the quality of the water outlets, further improve the sewage treatment capacity.

To build a tough city, the source of the source of the reducing sponge facilities and rainwater utilization facilities can also effectively share the pressure of rainwater to the drainage system during the peak of the drainage.

In recent years, Shanghai has implemented comprehensive rainwater comprehensive utilization projects in large agricultural parks, public green spaces, public buildings, elevated roads, and residential communities.

Take the residential community as an example. Through the rainwater garden, the grass gap, the water -transmitting pavement, and the related rainwater purification device, the rainwater can be "stayed". The purpose of saving water.

Shi Jiaming revealed that Shanghai is referring to time -sharing electricity prices to study the feasibility of time -sharing water prices, so as to guide residents to peak peak water and reduce the pressure of centralized drainage during peak periods. It is also a scientific method for improving urban sewage treatment capabilities. "In the future, many residents will choose to take a bath and wash clothes after nine o'clock in the evening, because in the future, water and drainage may be cheaper.

At the same time, Shi Jiaming said that the time -sharing water price should be used to install the smart water meter.

Recently, high temperature

Is there any guarantee for the supply of tap water in Shanghai?

Will the water quality be affected?

Shi Jiaming said that on July 14, the city's water supply reached 8.88 million cubic meters, a new high within the year, but it was far from the highest peak of history. Please rest assured that citizens were asked to rest assured.

From June 15th each year, Shanghai enters the peak of summer water supply. This summer, high temperatures above 35 ° C appeared earlier. After the plums on July 1, 3 high -temperature red warnings have been issued, which has superimposed the impact after comprehensively restoring production and life. The increase in water supply has increased significantly. From June 15th to July 12th this year, the average daily water supply of the city reached 8.559 million cubic meters, an increase of 1.49%over the same period last year.

In recent years, the highest peak of water supply in Shanghai appeared on July 21, 2017. The day temperature reached 40.9 ° C, and the city's water supply reached 9.58 million cubic meters. After the "highest peak this year" on July 14 this year, if the temperature continues to rise, it will not rule out the possibility of catching up with the highest peak of water supply in 2017.

However, Shi Jiaming emphasized that the current water supply capacity of 38 water plants in Shanghai reached 12.21 million cubic meters per day. The water volume was guaranteed, and there was no need to worry about "lack of water."

The quality of Shanghai tap water is also very stable, ensuring the high -quality water supply from the source to the faucet, and will not be affected by continuous high temperature.

In terms of raw water, Shanghai has built the four major reservoirs of the Yangtze River Chenxing, Qingcao Sand, Dongfeng Xisha, and the upper reaches of the Huangpu River. Jingmei's ecological reservoir. At the same time, a comprehensive "physical examination" is regularly for the reservoir to improve the safety and guarantee capabilities.

In various water plants, Shanghai promote in -depth treatment and transformation, and adopt technologies such as ozone biological activated carbon to further improve the key water quality indicators of tap water. At present, the city's water plant in -depth treatment rate has reached more than 70%, and it is expected that the end of the "14th Five -Year Plan" will be further increased to 90%.

The water plant is out of water, and pipelines and secondary water supply facilities are the key to determining the safety of water quality in the "second half".

The total length of public water supply pipelines with a diameter of more than 75 mm in Shanghai is about 40,000 kilometers. In recent years, Shanghai rolled the old water supply pipeline transformation in the annual rolling of the old water supply pipeline.

During the "Fourteenth Five -Year Plan" period, Shanghai will complete the update of the 2000 kilometers of old water supply pipe network, replacing the useful life of more than 30 years or the material is relatively backward, and there is a greater security risk pipe.

During the prevention and control of the epidemic in the previous stage, on the premise of ensuring epidemic prevention requirements and safety production, Shanghai completed the transformation of large -caliber and old pipelines at 32 intersections. In the past, these pipelines were in areas with heavy road traffic pressure. "Window period".

Among them, an old pipe is also a cast iron pipe set up in 1918 in Nanjing West Road (Shimen to Taixing Road). This time, it has also successfully completed the transformation.

At present, Shanghai has completed the secondary water supply facilities of 220 million square meters of old residential houses, and the water supply enterprises have implemented professional management, accounting for one -third of the city's secondary water supply facilities. Water supply companies are carrying out the investigation of secondary water supply facilities and hidden dangers to further improve water supply safety.

In addition, the Shanghai water supply industry is exploring digital transformation. For example, studying and constructing a smart pipe network system with forecasting and early warning functions can make the underground pipe network intuitively presented in front of inspectors without excavating roads or even continuous water. The technology has shown skills when the extreme cold wave invaded in early 2021.

Many communities have also created high -quality drinking water demonstration communities to promote the construction of smart pump houses, automatically monitor the quality of inlet and out of water in 24 hours, discover real -time alarm of problems, and even predict the amount of water for residents, control and reduce the time of tap water in the water tank to ensure water use of water use. "Fresh".

Before a pilot community, before the transformation, the average pool was 11 hours, and it was optimized to 6 hours after the transformation.

After basically eliminating the inferior types of water bodies, Shanghai wants residents to have "one river and one river" at the "door of the house".

Shanghai is a city with a dense river network, with 47086 (one) of rivers and lakes, with a total area of ​​649.2 square kilometers.

Since 2017, Shanghai has cumulatively rectified more than 5,000 small and medium -sized rivers and more than 18,000 inferior five types of water bodies. The quality of the city's water environment has been significantly improved. By 2018, it has basically eliminated black odor; by the end of 2020 ; In 2021, the quality of the water environment continued to be steady. The water quality of rivers and lakes above town management accounted for 70.7%of the three categories, and the surface rate of rivers and lakes reached 10.24%.

In the future, how can Shanghai's water environmental governance further enhance the sense of gain, happiness, and security of citizens?

Shi Jiaming, director of the Shanghai Water Affairs Bureau, said that during the "Fourteenth Five -Year Plan" period, the overall goal of Shanghai's water environmental governance was to further improve the water quality of the water body and make rivers and lakes more beautiful. Essence

During the "Fourteenth Five -Year Plan" period, Shanghai Water Environmental Governance will mainly work in four aspects.

The first is to continue to implement comprehensive rivers and lakes and highlight the concept of water systems.

"Many river channels are Unicom, which constitutes a water ecosystem, so governance must also be systematically, and they cannot 'be alone." Shi Jiaming said that during the "14th Five -Year Plan" period, Shanghai should strive to open up the breakpoint of all backbone river channels. At present There are still 118 places. The 300 -kilometer backbone river and lake comprehensive rectification project is implemented, and special water systems such as Dianshan Lake, Yuandang, and Jinhui Port will be created to improve the river network water system based on 226 backbone river channels.

Not only should the water be cleared, but the shore is also green. While the main veins of the water system and ensure the connection of the river and lake system, Shanghai will further penetrate the open space of the river bank, increase the proportion of ecological protection shores, and create a "one district, one corridor" water ecological corridor, so that each district residents in each district are at the "door of the house. "There is a proud" one river and one river ". The second is to carry out the construction of small ecological cleaning watersheds to create a hydrophilic environment for concentrated and connected films.

During the "Fourteenth Five -Year Plan" period, Shanghai will build 50 high -quality ecological cleaning small watershed with high -quality ecological cleaning in "smooth rivers and lakes, ecological health, clean and beautiful, and harmonious people. This year, the construction of 15 demonstration sites was completed this year, and the ecological restoration of small and medium -sized rivers of about 1,000 kilometers was carried out, and the health and natural river banks were reshaped to create a natural river and lake body.

The third is to promote the construction of rural domestic sewage treatment facilities and the improvement of bidding. By 2025, the city's rural sewage governance rate will reach 90%, and the quality of the water outlets will not be less than 90%.

Fourth, the heroic liability is theory of water quality.

At present, Shanghai has more than 6,300 rivers in cities, districts, streets, and villages, covering more than 47,000 rivers and lakes in the city. Controlling the sewage port and blocking pollution into the river ", the 166 corporate river chiefs were implemented in the 468 sewage ports of river entry into the river; more than 46,000 people with river protection volunteers and civilians were continued to strengthen the supervision of rivers and lakes management and maintenance. , Consolidate the effectiveness of water environment governance and improve the quality of water environment.

Shi Jiaming admits that rivers and lakes are a complex and Unicom system. The water quality of the river and lakes is affected by various factors. Therefore, there is always a problem of "repeated treatment and repeated" in the process of water control. In order to implement the responsibility of water management and ensure the long -term governance of the long -term clearing, the differences in the water quality differences in rivers and lakes in various districts are included in the evaluation system, accurately reflecting the governance of the river in the corresponding area, and "the hero is the hero."
