reporter yesterday from the Ji'nan Municipal Public Utilities Bureau, we learned that to cooperate with the construction of the ground road and environmental engineering of the Second Ring Road, the magpie mountain reservoir is required. The water conveyance pipeline of the 1800 km diameter line (3 km) along the Second Ring Road West of maghua water works is rebuilt and rebuilt. At present, the preparatory work for relocation has been completed. It is proposed to close the 5 old and new pipelines in the near future, and the construction period is expected to be 72 hours. This means that, on October 15th -18, during the construction period, the water supply plant of maghua, which takes 1/3 of Ji'nan's water supply, will stop supplying water.
[b] problem: the bridge pier can not be removed from the pipeline of water supply pipeline. Magpie Hua water plant will stop for [/b]
"Ji'nan second ring road construction including ground road and viaduct, among which, the construction of the viaduct must be buried. The buried depth of the pier is just in conflict with the water supply pipe. Therefore, we must adjust the line of the water supply pipeline when we build the viaduct. The staff of the Ji'nan water group said.
at 9:30 yesterday morning, the reporter arrived at the South four hundred meters south of the second ring road and the North circumference of the city. A big pit was excavated on the road, surrounded by blue construction. Reporters saw that there was a concrete pipe in the pit, and there was a section of steel pipe next to it. The construction staff told reporters that the cement pipe is the original water supply pipeline, and the steel pipe is the pipeline to prepare for the new access. "The downstream piers and relocated pipelines are 3 kilometers, involving 5 reconstruction and 9 junction points. The pipeline is the only raw water transportation pipeline from the magpie reservoir to the maghua water plant. During the construction period, the water treatment plant will cease to operate.
[b] influence: the daily water supply will be less than 1000000/3 people drinking water will be affected [/b]
according to the introduction, the magpie mountain reservoir water mostly comes from the Yellow River water, the water plant's raw water is transported to Magpie Hua water plant through the pipeline which will be reformed, and then transported into thousands of households after the water making of magpie water plant. While the water supply capacity of the water supply plant of the maghua water plant is 400 thousand tons per day, the actual daily water supply is 230 thousand to 250 thousand tons, which accounts for more than 30% of the total water supply in Ji'nan. "During the joint construction of the original water pipeline, the magphua water plant will stop production, and the city will face a 200 thousand cubic meter / day water gap, accounting for 1/3 of the total water supply in the day. The project will become the most suitable construction in Ji'nan in recent years. The staff of the Ji'nan water group said, "under the distribution of water sources and topography, during the opening of the pipe network, the water pressure will be reduced in the west to the Second Ring West Road, the south to the seven road, the east to the Middle Road, the north to the Second Ring North road. One of the most affected areas is on both sides of the MILITIAN Road, on both sides of Lan Xiang road and in the outer ring (on both sides of the West outer ring of Yingying Mountain North Road) and the West outer ring (Qinghe bridge - on both sides of the MILITIAN Road).
it is reported that the area of the depressurization is about 100 square kilometers, and about 1 million residents will be affected by water and water pressure. At the same time, there is no exclusion of water.
[b] measures: the temporary increase in underground water quality monitoring will synchronize [/b]
to make up for the water supply gap and ensure the safe water supply. The economic south city government approved the approval of the economic south city government. The Ji'nan water service group confirmed the mining principle of "first Jinxi, the West Suburb and the east suburb", from the two phase of Jinxi and the first phase of the water source; the eastern suburbs and The water source area of Dongyuan is 200 thousand cubic meters of water supply. At the same time, the output of surface water plants such as Yuqing and snow mountain will be increased, and all clear water tanks of all waterworks and pressurized stations will be run at all high water levels. "Previously, Ji'nan has been implementing measures to seal wells and protect springs, in order to ensure the continuous spewing of Baotu Spring for many years. But the construction has a huge impact. In order to ensure that the life of the residents is as little as possible, it is necessary to release the groundwater temporarily and make up the water gap in the whole pipe network. Ji'nan Municipal Public Utilities Bureau official said.
at the same time, Ji'nan water group said that due to the adjustment of the water supply pattern, the direction of water flow in the water supply network changes, the water in some users' homes may appear water rust or yellow phenomenon, this phenomenon is normal in the process of water transfer. When this happens, the public can turn on the faucet and let the water be clear when the water is clear. "The water that was originally supplied from the west to the East, because the water source in the west is gone, the water can only be transferred from the east to the west, the flow of water has changed, and the rust in the inner product of the pipe may be scoured and shedding because of the change of the direction." The staff of the Ji'nan water service group said they will also take the water quality laboratory personnel, check the water quality per hour at the water supply site, and deal with the water quality problems that may be found in the process. Increase the water discharge at the end of the pipe network to prevent the two pollution of pipe network water.
