yesterday is the world water day, while the water level in Baotu Spring in Ji'nan, Shandong, broke the "red line", which makes the Ji'nan citizens who give up drinking water and give full strength to preserve the spring. What is the current situation of water resources in Ji'nan? How is the water supply project going? Reporters learned that, according to the current reservoir storage capacity, if the Yellow River stops, the Ji'nan reservoir will last for two months.
Ji'nan has less water resources per capita than the whole country 1/7
yesterday was World Water Day. In January 18, 1993, the forty-seventh session of the general assembly made a resolution and was "World Water Day" every year in March 22nd. The purpose of the resolution is to promote the protection of water resources management and to solve the increasingly severe water shortage problem. The Ministry of water resources of China has designated from March 22nd to 28th as "China Water Week" every year. The theme of World Water Day this year is "water and sustainable development".
yesterday, the data released by Ji'nan Water Conservancy Bureau website showed that the Baotu Spring water level was 27.59 meters, and it officially fell below the 27.60 meter red warning line. At the same time, the water level of the black tiger spring is 27.52 meters, which is also low. Yesterday afternoon, reporters came to the black tiger spring pool to see that its water flow has decreased, the west side of the tiger's head water volume has been very small. It is estimated that the possibility of stopping Baotu Spring will be 90% this year.
it is reported that Ji'nan is a resource-based city of water shortage, the city's annual average rainfall of 639 millimeters, the total amount of water resources 1 billion 748 million cubic meters, the amount of available 1 billion 156 million cubic meters, the per capita water resource possession of only 290 cubic meters, less than the national 1/7. At present, Ji'nan is faced with the contradiction between the contradiction between supply and demand of water resources, and the pressure of water supply and spring maintenance.
magpie mountain and Yuqing Lake Reservoir impounded more than 70 million
it is known that the current source of Ji'nan includes surface water source and groundwater source. Among them, there are mountain reservoirs in the surface water source, which are the reservoir of yuhushan reservoir, Jinxiu Sichuan reservoir and wolf cat, and the plain reservoir, including the Yuqing lake reservoir, magpie mountain reservoir and East Lake reservoir. In
water source, the water source area of the east suburb includes the water source area of white spring, Li Zhuang and home, the water supply capacity of the design day is 200 thousand cubic meters. The water source area of the west suburb includes Mount Emei, Da Yang and La Shan three water sources. The water supply capacity of the design day is 250 thousand cubic meters. The water source area of Jinxi area includes ancient city, cold Zhuang and bridge Li San. At the water source, the water supply capacity of the design day is 200 thousand cubic meters. The foreground water source includes the prun gate, the liberated bridge, the south, the Yang head Valley, the Quancheng Road, the drinking tiger pool, the East eight Li WA, the Huaneng Road, 8 urban water sources, and the water supply capacity of 100 thousand cubic meters in the design day. In addition, there is a long filial piety water source (located in the Changqing District of CHO Lou, CHO Lou in Gui de Town, 100 thousand cubic meters of water supply capacity in the design day) and a high and new zone water source (including Dongyuan and Dong Quan water source).
at present, the Yuqing lake reservoir water storage capacity reached about 27500000 cubic meters, magpie mountain reservoir full capacity of 46 million cubic meters, the current volume of water storage reached about 43000000 cubic meters, nearly full capacity. Even if the Yellow River is cut off, two reservoirs will no longer carry water, and it will also ensure more than two months of water demand in the urban area. In addition, the Yuqing lake reservoir has two water sources to ensure that no longer water from the Yellow River can lead the Yangtze River into Yuqing lake reservoir.
East District water works will be completed in October five library connected two projects to start
today, reporters from Ji'nan Spring City Water Co., Ltd. to understand that the current water shortage in the East District of Ji'nan, the company is building the East District water plant, the project has already opened, is expected to be completed by the end of October. The eastern waterworks mainly serve the eastern urban area of Ji'nan. The water supply network from east to East is transferred from the Queshan reservoir, and the scale of the recent (5-10 years) is 100 thousand cubic meters / day. At the same time, the contract signing ceremony for the reconstruction of the water supply line of the reservoir (the village head pump station, Nankang pumping station) has been held in the construction and construction administration of the south to North Water Transfer Project in Ji'nan. Reporters learned that the project is "five storehouse connectivity" in the two phase of the project will start today, is expected to be completed by the end of the year.
the reporter learned that the reconstruction project of the water supply line of the reservoir is a water system connecting project to ensure the safety of urban water supply, improve the water environment and the ecological carrying capacity of the water in Ji'nan. The hushushan reservoir is one of the "large water tanks" in the southern part of the provincial city, which bears important tasks of water supply, spring maintenance, irrigation and flood control. After the transformation of the line, 3 water sources of Changjiang water, the Yellow River water and local surface water will be supplied to the southern suburb water plant and the watershed water plant. The water supply of 3 reservoirs of Xinglong, slurry spring and Mencius will be supplied, and 4 rivers, such as Xingji River, will be provided with ecological water, and the water supply system of Ji'nan is further optimized and the water supply guarantee rate is improved.
