recently, the municipal water conservancy bureau concerned said that at the end of this year, the capacity expansion of the reservoir and the five library connected workers The process will be completed and start to play a role. At that time, the reservoir of a medium-sized reservoir can be added to the reservoir of a medium-sized reservoir, with a maximum of 50 million cubic meters of Yellow River water or the water of the Yangtze River per year, and water replenishment for the rest of the reservoir through a connected project. Nanshan large water tank will become a sponge for the construction of sponge city.
although the pilot area of sponge city is located in the urban area, it is particularly important for the upper reaches of the pilot area to have adequate water supply as a source. On the morning of 13, reporters at the construction site of the five storehouse connected project saw that the tunnel between connected reservoirs was being opened to ensure that the water source would be convenient for future visits. Five storehouse connected project is one of the supporting projects of South to North Water Transfer in Jinan City. The relevant responsible person introduced, through the connecting of 5 reservoirs of supine tiger mountain, Jinxiu Sichuan, Xinglong, Shishui spring and Longquan Lake, 4 waterways of the southern suburb, the watershed, the Xingji River and the Daxin River, as well as the 8 strong seepage zones along the line, can be added to the water source. The end of the year will be achieved.
in the North Bank of the large reservoir in the south mountain area, the reporter saw that the project of lifting the field near the north bank has been completed. By digging the earthwork of the reservoir area, the amount of the stomach of the reservoir is increased, and 9 million cubic meters of water can be accommodated on the original basis.
Municipal Water Conservancy Bureau is also responsible for the management of the Longji River and Jinyun river. Through the excavation of the Longji River, the river slope regulation can improve the waterlogging capacity and improve the water ecological environment. Now the project has completed the bidding and the plan is started in the near future. Jinyun Chuan river management started construction in June 8th, and two river regulation projects are planned to be completed by the end of this year. In the southern part of the pilot region of the spongy City, the Xing long section, one of the key leakage zones in the spring supply area, is now planning to protect more rain and flood to allow more water to enter the land.
relevant responsible person said that in the past two years, Ji'nan suffered from drought, and the southern mountain area reservoirs used to drink water from the sky. After the completion of the water diversion project of Yufu River and the five reservoir connected to the reservoir, the large water cylinder of Nanshan can borrow about 50 million cubic meters of the Yellow River water or the Yangtze River water every year, making the city's sponge greatly reduced the worry of the water source.
the water supply of the south suburb water plant was supplied to the southern suburb water plant as the large water tank at the end of the year. The water supply to the southern suburb water works was 50 thousand cubic meters per day. But in September 2012, the water supply channel of the supine Hushan Reservoir was suspended for the city's water supply, and the water supply was suspended. It has not been restored.
13 days, the reporter saw in Nankang pumping station, a site on the route of water transportation, that the maintenance and renovation is being carried out. After the end of the year, the capacity will be raised from 50 thousand cubic meters per day to 100 thousand cubic meters, sharing the pressure of urban water supply.
100 thousand cubic meters per day reduced by
a strong drop in the previous period, the water level of the spring has risen, and the recharge of the reservoir in the reservoir has been few, and the amount of water recharge to the recharge has been reduced from 300 thousand cubic meters to 200 thousand cubic meters per day.
now there is a small amount of storage water. The responsible person in the management department of the reservoir management said that the surface runoff was not formed at the end of the heavy rainfall, and there was no water source into the reservoir. Because of the long drought, the surface runoff had a certain lag, and the land of Nanshan needed to be full first and then have excess water to flow into the reservoir. However, this part of the water resource is very small. It is best to have several effective rainfall, so that the reservoir can quench thirst.
