What assurance is water supply two times safe
Staff reporter Zhang Hao "Because pressure of municipal pipe networks is not enough, so long as the building of more than 5 layers all need water supply two times. The high building of Beijing is nearly all everywhere, over 100,000 units offering water supply two times, and apparatus and management level of every water-supplying unit are different, very essential to sanitary control of the water supply two times. " He JiMin, secretary of Beijing Health Inspection, says. In the morning of August 19, in Beijing " experience of one day that the public health works " In the activity, the reporter works with more than 10 persons who experiences citizen, the supervisor who follows Beijing Shijingshan District Health Inspection Institute comes to a residential quarter, it experiences sanitary control to be how launch, supervise, monitor to two water supply and the intersection of tip and water. One is checked two looks three is measured and entered between water supply two times in the Residential Area, the supervisor Lu Jun looks over whether licence and staff members' health card of this water-supplying unit are complete at first, whether the everyday control record is complete. He introduces, these are " software " Inspection,it is too daily in not supervising to check often by place that be gone wrong most, it correct in time for to want to problems little, the big problem will take the punishment measure soon. Have checked " The software " And then, the health supervisor begins to look over the apparatus of the hardware especially. Water supply two times is more than half and is occupied by a very large metal water tank. It is introduced, this is the mode that water supply two times of most buildings is adopted at present: Build one big water tank in basement, pressurize, transport upwards ink of water tank through water pump and then, give 6 and resident of the above supply water. Lu Jun gets on more than 3 meters of high water tanks, looks over the whole situation of the water tank first from the cover opening. "Whether have a rust mark on the intine, whether have alga and floating thing in water, should have a simple sense organ that knows to its inside at first. " "It is not enough to only have perceptual knowledge. " It is supervised at ordinary times that persons who tell citizens to experience of Lu Jun, " except will supervise the course of supplying water, the key will measure the result of supplying water, will judge whether water reaching resident's home is qualified finally. " Subsequently, he has gathered water of tip from the faucet, measures with the portable instrument. "To the detection of water of tip, depend on whether the appearance is transparent and clean, there is peculiar smell to then take a sniff at and hear at first. Then measure turbid degree, pH value and my chlorine of water with the instrument separately. Certainly, these daily contents supervised, if will demand to include the whole inspection of 106 indexes after discovering the problems. " Lv Jun's additional remarks. Through measuring, water water sample of tip gathered is qualified. It is newer too that the old apparatus of the grown-ups and children district is the greatest hidden danger " to look like such a new Residential Area apparatus, so long as there is not slip in managing, there should not be questions in the water quality of water of tip. The ones that most possibly went wrong are some grown-ups and children districts that uses the old apparatus. " Lu Jun tells reporters. In using water pump is water water tank to rooftop,and then through gravity from at supply water downwards. Some old water tanks are not stainless steel, some or even casting iron. It is introduced, in case of normal water supply, these water tanks have no question, but if present the situation of cutting off the water, it is very apt to get rusty after the moist body of case keeps in touch with the air, the water quality that the water tank gets rusty and influences water of tip directly is safe. The intersection of property and administrative staff of Residential Area tell reporter whether at present, another kind there is no negative pressure, supply water the apparatus, needn't build big water tank, can use the pump and can reduce a link that may pollute water to the water supply on the senior level directly. But because these apparatus purchase and the operation cost is relatively high, the popularity is not high. Persons who tell citizens to experience of Lu Jun, because the problematic apparatus is an important hidden danger, will lay particular emphasis on it to some extent in supervision soon. At present, require each water tank to wash sterilizing twice in one year, will gather the water sample and carry on water quality detection after washing, the content will contain more overall indexes such as heavy metal particle, radioactivity, bacteriology index,etc., it is totally qualified to continue supplying water to only measure. Emergency can adopt administration control measure " appear, initiate the situation that infectious disease break out by water pollution of running water, what measures will Ministry of Health take? " In the course of experiencing, elder sister Su from research institute of planning and design of city of China quizs one. Lu Jun answers, at first, should propose patients go to the hospital to seek medical advice as soon as possible, check in an all-round way, in order to confirm whether the patient's disease relates to running water. Certainly, generally the infectious disease question that the running water initiates is mostly group sent. Take place large the intersection of area and many people present symptom of suffering from diarrhoea, vomiting etc., when every clue brief on with the running water correlated withing, the superintendent office of the hygiene can assign the administration and control the decision book. "The administrative control measure includes sealing up for safekeeping and supplying water of the apparatus, suspending the supply of running water, change into that the way is supplied water of temporarily using the car in year by the running water company. Then, the Ministry of Health wants to the source of water, water, water supply pipeline and water supply apparatus two times of factory,etc. each link implementation appear to check in an all-round way, will not resume normal water supply until finding and solving the problem. " The health supervisor further explains. He JiMin tells persons who experience, the superintendent office of the hygiene is strengthening and supervising and making scheme of meeting an urgent need at ordinary times. If citizens find water quality goes wrong, should contact hygiene superintendent office in district, county in time, or phone " 12320" Reporting of the offence.
