Shandong commercial newspaper
in the construction of Ji'nan sponge City, urban water system occupies the first place in the four major construction of sponges. The reporter was informed yesterday that the five database connected projects that started this year have been completed in half, and the expansion project of the reservoir will be completed at the end of the year. Not only the 4 rivers in the city will have fixed water sources, but the water supply in the southern part of the city will not be seen again. The construction of these projects will also detained 3 million 537 thousand cubic meters of rainwater resources for the construction of Ji'nan sponge city water system. Wen / TU reporter Gao Yulong
five libraries will be connected to the 4 channels of the urban area, which will provide water
five reservoir connected projects started in October last year. It plans to supply water to two water plants in the southern suburb and the watershed through the five reservoirs of supine Hushan, Jinxiu Sichuan, Hsin long, Shishui spring and Longquan lake. Ecological replenishment is also carried out in 4 urban rivers and 8 strong springs in the southern part of the city, such as Xingji River and Daxin river.
reporters yesterday saw the construction of a new tunnel between the Xinlong reservoir and the water spring reservoir at the site of the construction of the five storehouse connected to the construction of the Xinlong reservoir. According to the relevant person in charge of the Ji'nan Water Conservancy Bureau, three reservoirs are connected through the Xinlong reservoir and the slurry water spring reservoir, and the new 3.84 km and 2.54 km tunnel of the slurry reservoir and the Mencian reservoir. "At present, the tunnel of the Xing Long reservoir has been through five hundred or six hundred meters, and the rest of the other five connected projects have been basically completed. It is expected that by the end of this year, the entire five library connected projects will be able to build water." In addition to the completion of the five reservoir connected projects, the above-mentioned responsible person said that, in addition to the water storage of the reservoirs, 4 rivers, such as the Xingji River, Daxin River, and the strong seepage zones of 8 springs in the southern part of the urban area, can be used for ecological water supplement, and its function in the construction of the sponge city can be played.
after the expansion of the 7 Daming Lake
reporter at the construction site of the expansion project of the supine Hushan Reservoir, the eastern reservoir area of the reservoir has basically dried up, nearly ten large operating machines are under the base of the reservoir, and the original farmland is also being built up on the North Bank of the reservoir. According to the person in charge of the project of the expansion project of the reservoir, the main contents of the dilatation of the supine Tiger Mountain include the excavation of the reservoir, the construction of the field, the construction of the ring road and the surrounding demolition. "Now the project has been completed basically, and the demolition work has been completed in half. The ring road will be carried out in the near future, and the project is expected to be completed by the end of this year."
after the completion of the project, the water level of Xingli reservoir will be recovered from 129 meters to 130.5 meters, the capacity of Xingli reservoir will reach 63 million 740 thousand cubic meters, and the capacity of Xingli reservoir will be increased by 9 million cubic meters, which is equivalent to 7 Daming lakes. "The increase of the 9 million cubic meters of storage capacity, we will be able to collect more rainwater resources, which will greatly guarantee the water supply of the residents, and more resources to recharge the source, promote the construction of Ji'nan sponge city."
wolf and cat landscape reservoir can be known for the eastern emergency water supply (
). The wolves and cats landscape repository had been carried out and strengthened, and the water storage conditions were available in the second half of last year. The wolf cat storehouse, which had been shut down for a long time due to recent heavy rainfall, began to store water at the end of July, and now the water storage capacity is 3 million 380 thousand. The responsible person in charge of the municipal water supply department said that if the water storage can reach four and five million parties, the water plant, which is stopped because of the unavailability of water, is expected to restore water supply, which can provide 20 thousand tons of water per day.
for nearly a week, the daily water supply in Ji'nan is still around 750 thousand, and is still at a high level. It is understood that the city has a water supply gap of about 100 thousand parties every day, mainly in the eastern part of the city. On the basis of measures such as the west water east transfer and the adding water pool in the pressure station this year, the water supply gap in the region is still around 30 thousand parties. "Because the water source of the wolf cat reservoir is all derived from atmospheric precipitation, it is very important for the reservoir and water plant to be reactivated." If there is precipitation next week, the chief said, the snow mountain water plant will be more likely to restart it, and the amount of water that has been stored may be reduced if continued drought.
