A Jiangxin Hekou Reservoir, as big as Hangzhou 10 West Lake, not only makes the long-term expectation of Shanghai residents to drink high-quality Yangtze River water come true, but the effective storage capacity of 438 million cubic meters is enough to ensure the normal water supply for 68 consecutive days, even in the face of the invasion of salt tide in the East China Sea, alleviating the once stagnant "heart disease" in Shanghai, rewriting the history that Shanghai mainly relies on Huangpu River for drinking water, fundamentally changing the urban raw water supply pattern and perfecting Shanghai.
This is a feat of the times, strong in the vastness of the project, strong in the party's thinking and the people's will.
This is a beautiful thing in the world, beauty lies in nature, beauty lies in the realm, and beauty lies in each of us.
In order to let the people of Shanghai drink good water
Drinking water is the "first grain" for people.
Shanghai, located on the coast of the East China Sea, at the mouth of the Yangtze River and the water of Taihu Lake, was once named "Shanghai" because of its rich water resources. For a long time, water is a special gift from nature to Shanghai, because Shanghai has its mother river-Huangpu River. It stands to reason that Shanghai's water area is not small, accounting for one-sixth of the total area of Shanghai, but it is one of the six water-deficient cities predicted by the United Nations in 2 1 century, and it is a typical water-deficient city. Shanghai is not short of water. What Shanghai lacks is good drinking water.
All along, the worry of good water has been with you. At the same time, Shanghai has never stopped its efforts to improve the quality of citizens' drinking water: since the last century, Shanghai's water sources have undergone several migrations. Suzhou River and Huangpu River are the earliest water sources in Shanghai. First of all, the water quality of Suzhou River deteriorated, and the water intake in Shanghai was forced to move to the vicinity of Simon Road in Huangpu River. By 1978, people found that the fish and shrimp in the lower reaches of Huangpu River were almost extinct, and the water intake was forced to swim upstream. After ten years,1July, 987, the water intake had to be moved to the Linjiang section of the upper reaches of Huangpu River again. 1July, 1998, the second phase project moved the water intake to the waters near Songpu Bridge in the upper reaches of Huangpu River. The water source has moved again and again, but Shanghai has not got rid of the shadow of "water quality deterioration". In fact, the upper reaches of Huangpu River are also the lower reaches of Taihu Lake Basin. Due to the influence of pollution, most of the open flowing raw water from the upper reaches of Huangpu River belongs to three or four types of water, and sometimes even five types. In order to ensure the quality of tap water, the waterworks have to use heavy chlorine for disinfection and sterilization, and the dosage is even four times that of the past.
Where can I find clean water, the Yangtze River estuary and the riverside.
The quality of drinking water in Shanghai has become an urgent problem in Shanghai's urban development. We should make such a historic thinking and make such a historic choice.
From 65438 to 0987, the Shanghai Municipal Science and Technology Commission launched the project "Study on the Second Water Source of the Yangtze River —— Shanghai Urban Water Supply Planning Scheme", which opened the prelude to the research, development and utilization of drinking water sources in the Yangtze River estuary of Shanghai.
1990, Shanghai Water Conservancy Design Institute put forward the suggestion that "promoting siltation is not feasible, but confining water is feasible", and planted the first scientific seed of water in the green grass sand circle. Therefore, the water source of green grass and sand has attracted much attention. Qingcaosha water source is located in the northwest of Changxing Island, which is an alluvial sandbar in the Yangtze River estuary. The annual transit runoff is about 933.5 billion cubic meters, which is 100 times that of Huangpu River. More importantly, the water quality of Qingcaosha water source area is clear, reaching the national second-class standard and meeting the water quality requirements of national urban centralized drinking water source area.
199 1 year, a group of experts such as East China Normal University and Shanghai Environmental Protection Bureau put forward the scientific idea of "taking water from the middle reaches of the Yangtze River and turning Changxing Island into a water source island".
From 65438 to 0994, Shanghai Raw Water Co., Ltd. successfully developed the first salinity observation station in the Yangtze River estuary-Qingcaosha Salinity Station, which laid a research foundation for the observation of sediments and salt sequences in the Yangtze River estuary.
During the period of 1996, the Shanghai Municipal Construction Committee organized the "Pre-feasibility Study on the Water Source of Qingcaosha in the Yangtze River Estuary of Shanghai", which formed a series of reports on the study of Qingcaosha.
200 1, the water source area of Qingcaosha was included in the Shanghai Urban Master Plan approved by the State Council (1999-2020).
In 2004, the water source of Qingcaosha was included in the key points report of comprehensive improvement and development planning of the Yangtze River estuary by the Ministry of Water Resources.
In 2005, Shanghai City Investment Corporation organized the Municipal Raw Water Co., Ltd. and other 12 units to complete the general report on the feasibility study results of raw water project in Qingcaosha water source area and the 16 special report. Through scientific argumentation, it is proved that Qingcaosha water source area has comprehensive advantages such as abundant fresh water resources, excellent and stable water quality, favorable river regime stability in the north and south ports, etc., which fully conforms to the overall layout of Shanghai's urban development and the "century-old" strategic requirements of Shanghai water source area, and Qingcaosha water source area has become the first choice for Shanghai's new water source area. June, 5438+February of the same year, Shanghai Water Affairs Bureau hosted the "Shanghai Yangtze River Estuary Water Source Evaluation Meeting". Twenty-six academicians from nine disciplines in China formed an expert group and listened to the report of "Raw Water Engineering Research Results of Qingcaosha Water Source". The 26 academicians and experts attending the meeting agreed that the construction of water sources is a century-old plan and is of great significance to the safety of water supply in the city. Based on the comprehensive analysis of safety, stability, reliability and operability, it is suggested that the construction of Qingcaosha water source project should be started as soon as possible during the Eleventh Five-Year Plan period, and the preliminary project plan of pre-feasibility study is basically agreed. The meeting formed the "Opinions on Evaluation and Review of the Research Results of the Yangtze River Estuary Water Source in Shanghai" and submitted the "Request for Instructions on Accelerating the Planning and Construction of the Yangtze River Estuary Water Source in Shanghai" to the municipal government.
Thus, 65438+20061October 20th became a milestone in the history of Shanghai's water supply development: the Shanghai Municipal Party Committee and the Municipal Government made a plan to "expand the development and utilization of water resources in the Yangtze River and build a water source with lush grass and beautiful sand ...", which was approved by the fourth session of the 12th Shanghai Municipal People's Congress and formally written into the 11th five-year plan for Shanghai's national economic and social development.
In order to embody the "centennial" strategy in the project
This is a kind of seeking truth and being pragmatic. On May 8, 2006, the executive meeting of the municipal government and on May 5, 2006 15, the Standing Committee of the Municipal Party Committee respectively listened to the report of the Municipal Development and Reform Commission on promoting the construction of water sources in the Yangtze River estuary.
This is a kind of foresight. When planning the development and construction of Qingcaosha water source area, the Shanghai Municipal Party Committee and Municipal Government put forward: "The drinking water source area should make full use of the Yangtze River water source and have a' hundred-year' strategic plan ..."
Yes, the construction of Qingcaosha Project is no less difficult than the Three Gorges Project. There are too many problems to be solved to turn the blueprint into reality. There is no precedent in the world to build a large reservoir in the estuary area, which is a great pioneering work full of whimsy. To accomplish such a great pioneering work, we need to do our best; To achieve such a great initiative, we need to work hard. If it is difficult to demonstrate 15 years, then in the next five years of design and construction, the engineering problems to be studied are more realistic, and there are countless engineering difficulties to be overcome, including whether the world's largest Jiangxin Hekou Reservoir can be built, including whether it is feasible to promote large-diameter and long-distance river bottom water pipeline by shield method, including the location of the largest super-large water intake pumping station in Asia, and how to solve the problem of salt tide intrusion into Jiangxin Hekou Reservoir. ...
All eyes are focused here, and all wishes are pinned here.
Under the leadership of the engineering headquarters with the Deputy Secretary-General of the municipal government as the chief commander, marked by June 5, 2007, a century project benefiting people's livelihood began to start, and a grand blueprint began to appear in the hearts of Shanghai people in a three-dimensional way.
The raw water project of Qingcaosha water source area consists of nine major projects, including Qingcaosha Reservoir and intake and delivery pump gate project, Yangtze River raw water conveyance tunnel project, onshore water conveyance pipeline and pressurized pumping station project. After the completion of the project, the raw water from the Yangtze River enters the Changxing Island water conveyance tunnel through the intake pump sluice, reservoir and water conveyance sluice well, then flows across the river by itself through the raw water pipeline of the Yangtze River, and then is lifted by the No.5 ditch pumping station in Pudong into various water conveyance branches, and finally reaches 14 water plant.
"Integrating wisdom into society", Qingcaosha team has formed such * * * knowledge in engineering construction. Because as we all know, we must rely on experts to check and break through the "bottleneck" in the vast project that is fully rolled out in the future. So an expert committee led by an academician was established, consisting of 22 experts, involving water conservancy, tunnels, basic engineering, automatic control, water production, environmental protection and other disciplines. In order to respect science and knowledge, and give full play to the guiding role of the expert committee, the engineering headquarters made a decision that all major decisions in the project must be reviewed by the expert committee.
If "integrating wisdom into society" is compared to one leg of grass-sand project, then "innovation drive" is the other leg of grass-sand project. After the establishment of the Committee of Experts, the Committee of Science, Technology and Management Innovation was established one after another. This scientific and technological innovation team in Industry-University-Research, with Qingcaosha Company as the main body and the winning design unit, winning construction unit, winning consulting unit, relevant universities and research institutes as the backbones, has formulated the Measures for Scientific Research Management and Detailed Rules for the Implementation of Scientific and Technological Management and Innovation from the very beginning, and at the same time formulated the scientific and technological innovation plan of raw water engineering in Qingcaosha Water Source Area, compiled the implementation plan of scientific and technological innovation, and defined the tasks, goals and objectives of scientific and technological innovation of raw water engineering in Qingcaosha Water Source Area. In the following time, Qingcaosha Company successfully applied for 3 scientific research projects of Shanghai Science and Technology Commission, and the scientific research project of the Municipal Construction Committee 1; In cooperation with scientific research institutes, more than 30 scientific research projects have been carried out, such as the experimental study on the longest continuous days when Qingcaosha Reservoir is not suitable for water intake, the study on the influence of river regime in reservoir engineering, the model experimental study on scour prevention and beach protection in reservoir engineering, and the experimental study on pump selection in reservoir engineering. The corresponding scientific research achievements have been applied to effectively guide the construction of water source projects, among which the Standard for Inspection and Evaluation of Joint Quality of Drainage Sluice Project of Qingcaosha Reservoir, which was drafted and published in combination with engineering practice, also filled a gap in engineering specifications.
To build a century-old water source project, there is no retreat, only to gather wisdom and work hard to find a road of scientific and technological innovation in practice. Although the difficulties encountered and the efforts made are unimaginable to ordinary people, the Qingcaosha team has created several projects that attract worldwide attention: the 800-meter trunk Longkou has created the best interception technology for Hekou Reservoir, the 7.2-kilometer water conveyance tunnel has created the one-off tunneling technology for medium-diameter shield, the high-lift large-scale pumping station has created the best land-saving and electricity-saving technology, and the reservoir science demonstration base has created the best pre-control technology for eutrophication of lakes and reservoirs ... especially, the construction of a reservoir in the middle of Hekou River is a pioneering work in Shanghai and China, and also in the world.
In order to realize the vision of "a better life"
Raw water is precious, and the city is silent.
Green grass and sand, a century-old strategic water source in Shanghai, have finally turned from "Arabian Nights" to reality. After the Qingcaosha water source project officially entered the commissioning stage from 20 10 1 0, after a month of equipment commissioning and pipeline flushing, the newly-built Pudong Jinhai Water Plant was the first to be connected to the grid to supply water to users on 2010/. After Jinhai Waterworks was flooded, Qingcaosha Reservoir supplied water to Yangshupu, Heather, Jujiaqiao, Lujiazui, Linjiang, Lingqiao and Changqiao Waterworks for three times, and supplied water to all seven administrative districts of Shanghai, such as Changning, Xuhui, Luwan, Jing 'an, Huangpu, Hongkou and Yangpu, and some areas such as Pudong, Putuo, Zhabei, Minhang and Qingpu.
"The good water of the Yangtze River will be preserved before it flows into the East China Sea to benefit the city of Shanghai and the people of Shanghai." Shanghai finally let tens of millions of people in Shanghai drink the water from the middle reaches of the Yangtze River, which fundamentally reversed the serious shortage of qualified water sources in Shanghai and made the raw water from the Yangtze River account for 50% of the city's raw water supply.
In order to realize the vision of "a better life", Shanghai has not stopped her steps.
According to the forecast, by 2020, the total demand of raw water in the city will reach 654.38+04.28 million cubic meters per day, and the four major water sources built in Shanghai are Qingcaosha in the Yangtze River, the upper reaches of Huangpu River, Chen Xing in the Yangtze River and Xisha in Chongming Dongfeng. Among them, the water source of Qingcaosha is supplied to the central city, Pudong New Area, Changxing and Hengsha Islands; Chen Hang water supply Jiading and Baoshan; Dongfeng Xisha water source is supplied to Chongming Island; The water source in the upper reaches of Huangpu River will supply Qingpu, Songjiang, Jinshan, Fengxian and Minhang. By then, the Yangtze River raw water will account for about 70% of the city's raw water supply.
Good water flows around us and in our hearts. Shanghai is lucky! Shanghai people are lucky.
