each district will produce a large number of sewage every day. According to the current water saving requirements, some residential sewage needs to be "settled on the ground". The reclaimed water station is a facility to treat and reuse sewage. The data provided by the water saving department show that there are 206 water stations in Ji'nan at present, excluding the middle water stations of universities, hotels and industry, and more than 90 middle water stations in the city. At present, nearly 30 residential areas are in idle or intermittently suspended state.
middle water station is idle, the sewage flow to municipal sewage pipe, causing the pressure of the downstream pipeline to increase, and even the rainwater to snatch the sewage channel, the pipe network overflow, the pollution of the river and so on. Why don't you spend a lot of money on the water station? What is the interest chain behind it? The reporter opens a secret for you.
field survey
the location of water station in mystery, function empty
reporter has received complaints from residential community residents, the water station in the residential area has not been used.
18 morning, the reporter came to the District, for the district water station whether to stop, the staff of the property is not clear. Later, reporters said they wanted to go to the water station. The staff claimed that they could not go in. They were all equipment rooms, and they had no keys.
reporter asked Ji'nan Office of water conservation staff know that the district water station is located in the underground garage. When reporters went to the underground garage, they were stopped by property officers and said they could not look at it. Subsequently, reporters randomly interviewed many residents in the District, who expressed ignorance of the location and function of the water station.
City water saving office staff said that the water treatment equipment in the district is aging, and it has been discontinued. It is not known when the middle water station will be activated.
the location of the middle water station in the residential area is concealed and empty.
18 noon, in the Ginza Jing Du international community underground parking lot, the reporter turned more than an hour in a corner to find the residential area of the water station.
the gate of the water station in the cell is locked, and the door is written with the 4 words of "reclaimed water engine room". The machine room was quiet, unable to hear the roar of the machine, nor could it hear the voice of the personnel.
subsequently, reporters from the city water saving office verified that the district water station has been suspended. The function of
water treatment station is to treat sewage, and the process is not complicated. The domestic sewage in the district is collected through a number of underground sewage pipelines to the water station. After a series of technological processes, it becomes the reclaimed water. The medium water can irrigate the green space, clean the road, create the view of the water landscape of the district and so on. It can be called the benefits of environmental protection and water saving.
now that the cost of building the station has been built, why is it idle now?
benefit chain
processing cost high to let the property "ignore"
at present, Ji'nan has a total of 206 large and small water stations, university campus, hotel, industrial water station generally run better, idle or intermittent operation mainly concentrated in the district water station.
now the new residential area requires the construction of reclaimed water treatment equipment. Most of the middle water stations are built by the developers and then transferred to the residential property management. The operation of the medium water equipment will cost a certain amount of time. After a period of time, the property company is idle because of the failure of the machine or the cost of reusing the middle water treatment cost, which leads to the idle of the water station.
water saving Department figures give a reporter an account. At present, the cost of water treatment per ton is 1 yuan to 1.5 yuan, while the price of water supply for residents is 3.15 yuan per ton. The cost of water treatment seems relatively low, but the cost is not low with the cost of equipment maintenance, labor and electricity. "The larger the scale of the reclaimed water station is, the more water reuse will be, and the more efficient the water station will be." The head of the water saving office has made an analogy. If a district can handle 100 tons of reclaimed water and reuse 100 tons of reclaimed water, it will save money naturally. But a small area of 100 tons of water, because of small size, green space, the need to clean the road is not much, so only 10 tons of water can only be reused, so that the cost will be improved.
at present, the low reuse rate of medium water is mostly concentrated in small and small water stations in small communities, which is also the main reason for the idle or intermittent operation of the water stations in these communities.
where to go from
water station to public?
water station does not work, environmental protection and water conservation can not be mentioned.
every year the municipal water saving office will raid the middle water station and make rectification notice to the district that does not use the medium water equipment, but because the water saving office does not have the right to punish, the residential property does not attach importance to the property, and it is mostly perfunctory.
people in the Department of water conservation said that some of the water stations in the residential areas were in idle state, which not only caused the waste of resources, but also affected the capacity of sewage treatment. If all the reclaimed water stations are fully operational, the daily sewage treatment capacity can reach 300 thousand tons, equivalent to a new sewage treatment plant. To this end, the municipal department plans to recycle and transform the water station.
the responsible person of Ji'nan municipal administration has said that priority should be given to reclaiming the intermediate water treatment station with daily handling capacity of more than 1000 tons. At present, there are 67 reclaimed water stations with a scale of over 1000 tons in Ji'nan. Only 3 of them have been upgraded through recovery and upgrading.
medium water station in green spring area is a successful case of recovery. Municipal Water Saving Office in charge of the responsible person, the water station was originally built in the community, only responsible for the collection of sewage in the community, later discussed, and replaced by the municipal department. After its construction, it will expand its scale not only to deal with the sewage in the District, but also to deal with the sewage from the surrounding areas.
of course, the water station in the residential area will be hosted by the water saving office. After that, the water station will be named "public" and there will be no outage.

China water station is not willing to pay small no one to receive
although there is a recovery plan, but it is also a priority to recover the water station with more than 1000 tons of daily processing capacity. "Large-scale reclaimed water station we want to get back, but people are unwilling to hand in it. Even if the small scale water station is collected, it will be difficult to upgrade the transformation space. People in the Department of water conservation said that the recovery of reclaimed water stations could not be completed in a short time.
take the water station of Xiucheng middle water station and the famous water station of famous man in the city as an example. The water stations of the two large communities operate normally, the green land is irrigated, the road is cleaned, the water landscape is made, the water is used, the return rate is high, the cost is relatively reduced, and the residential area is naturally unwilling to transfer the water station.
and the small scale water station such as the Ginza Crystal Capital International, Da Shun Tian become such small scale water station, the utilization rate is not high, the equipment has also already aged, even if want to transfer, the water-saving department does not want to accept.
the water station in the residential area can not be effectively used, some of the urban sewage will be discharged into the municipal pipeline, some even into the Xiaoqing River, causing local river pollution. How to make the best use of the water station in the district needs policy.

water station is easy to use up difficult
developers to build a house, must be equipped with water facilities, large areas with large medium water facilities, there are clear policy provisions. However, China's water supply facilities are facing difficulties in building policies and late supervision.
since August 1, 2006, the construction of the medium water facilities has been incorporated into the procedure for examining and approving the basic construction of Ji'nan, and the construction of the middle water project is changed from the post management to the construction diagram. In short, if developers do not match the reclaimed water facilities, the house will not be built.
at present, Ji'nan municipal water saving office does not regularly check the operation of water facilities in the residential district every month. "The notice of reform is much more open. Developers or property will not be serious." City Water Saving Office official admitted that the current water saving departments have no right to punish the illegal use of water stations, and it is bound to lag behind other departments. In addition to regulatory difficulties, there are still many gaps to be filled for reclaimed water use.
the current "measures for water conservation management of Ji'nan city" was established in 1996. Some of these regulations have not met the current requirements of urban water saving, such as hotels, restaurants, stores, apartments, comprehensive service buildings and high-rise residential buildings with a building area of more than 20 thousand square meters, which must be set up in the construction of water. Shi. Now, how to save water and how to reuse the water in the 20 thousand square meters of residential areas and units should take corresponding measures.
