 Background: Water is the source of life, our life is absolutely dependent on water, health and safety of drinking water is our most basic needs. Since July 1, 2007, the National Standards Commission and the Ministry of Health revised the drinking water health standards and the national standard of 13 drinking water health testing methods implemented. The standard is a mandatory national standards, this revision is the first revision since the first release in 1985, all indicators of the original 35 to 106, eight of the 35 indicators and the original standard amendments. Various indicators, it may cause harm to human health or the potential threat indicators accounted for about 80%, about 20 percent are affecting water quality sensory properties and the general physical and chemical indicators, the new standard toxicological indicators is almost five times the original standard. The new standard also stipulates that no later than July 1, 2012 106 indicators of drinking water all the standards, that is to transform all the facilities of the five years of the implementation of the new standard, July 1, 2012 all the targets implemented. Improve service quality in order to protect the residents of safe drinking water, water companies, the people calling will not cause secondary pollution of water supply pipe network of water quality products on the market, as soon as possible to avoid water supply output standards drinking water pipeline network dirty lead to water quality suffer from the phenomenon of secondary pollution. To adapt the provisions of the above requirements and the new water meter national standard (GB/T778-2007), Association of National Metrology Meter Working Committee requested a water meter manufacturing from June 1, 2010, the phasing out of gray cast iron water meter case, the use of new water quality will cause secondary pollution, alternative materials. According to experts, the most frequently used case of meter iron foundry casting, spray treatment can slow the rust, but rust is inevitable, and calcium oxide in the drinking water easily gives the liver damage. The copper case is the international meter the most widely used, but the lead contained in copper case will produce secondary pollution on water quality. The plastic case on the human body no harm, but can not stand the sun and rain hot Kushu, the cold harsh environment, the quality is not very stable. The aluminum alloy case in recent years the development of trial, but the coating is difficult to achieve permanent protection of aluminum alloys contain harm the human body elements also adversely affect drinkers body. Stainless steel due to its unique advantages for health, environmental protection, long life and other materials can not be replaced, will become the most scientific alternative material of gray cast iron water meter case

 Water Authority levy to treat water "remedy, the public suggested that the first payment after the IC card charging methods Water" won the first prize 
 How to better manage the still scarce water resources in Dalian, Dalian Municipal Water Authority to the city from all walks of life to seek the "good practices" from April 17 this year, 4 months, received a total of 165 recommendations of the community: including how to strictly controls the sauna Pirates of the water, the implementation of the IC card charges. Yesterday, the Water Authority after selection, a number of valuable recommendations which were commended. 
 IC card water meter is more scientific and effective 
 This reporter has learned that the "suggestions", not only in the Water Authority system, some NPC deputies and CPPCC members, retired cadres also involved. 
 Dalian Municipal Government and the rectification of the Office of the Ombudsman in an investigation report, Yong-De Zhang, recommended the adoption of new technologies to reduce operating costs, "he said, new technologies, is proposed to change the traditional water bills charged to rely solely on human meter reading, not only inaccurate, but also increase labor costs. IC card charging methods now used by the electricity, gas, public transportation, not only the accuracy of the science, the technology is very mature, and can be borrowed, set to become the first payment, after the water when the water is about to run out will be prompted to encourage the general public pay according to their water consumption water, water conservation. 
 Yong-De Zhang recommendations of the Water Authority attaches great importance to more than 70 of 12 third prize was named in the 165's proposal. Yong-De Zhang recommendations of the top prize. 
 Water Affairs Bureau Lang connected and highly appreciated the activities, he said that these proposals will be full investigation. As a key to solve the urban and rural drinking water safety, to solve the public is most concerned about, the most yearn, in accordance with the urgent, then slowly, first the easier plan step by step principles to be addressed. 
 The sauna center Pirates of the water there are still 
 Sauna industry because of the large quantities of water, prone to the behavior of the Pirates of the water has been noted. Great resistant Pumps Limited Warranty Minister Li Zhi said, after an investigation found that the Golden State sauna Pirates of the water situation is very serious, some sauna center claiming to be underground drilling wells are, in fact, theft of water, residents in the vicinity of water has been greatly impact. There are individual sauna center of arrears of water charges, the amount of amazing. 
 Li Zhi believes that the implementation of technical controls should be water on the sauna, the sauna industry, households, the single-form tube, through the transformation of the sauna center with the public use of water pipes stripped meter out to the well, so that can effectively control the phenomenon of Pirates of the water, at the same time cooperation with the business sector, sauna center of the newly opened water to the water sector for approval. 

 Design deviation from the measurement function 

 Residents that the electronic smart meter is installed, some of Cary is obviously money, suddenly without water; some IC card water meter batteries, but off, the use of two or three years after the damage caused by the water meter stall; IC card water meter quality standards, after magnetic plug with three or four times can not be used. 

 For many years engaged in research and development of measuring instruments Shenzhenshixing source ASDC Technology Co., Ltd. technical director, senior engineer Li Hongwei, technically speaking, the electronic smart meter automatic meter reading system for the accumulated pulses pulse table, this way to achieve Far EasTone, its reliability depends on the reliability of the pulse letter sheet letter, the pulse signal transmission and system measurement. "The reality has proved the reliability of these links is not guaranteed." Technical principle determines the event of the ordinary mechanical vibrations of the table body, external electromagnetic interference, power supply problems, the table upside down, the signal magnet demagnetization, the accuracy of the table a letter will be affected; pulse signal transmission line failure, or to connect the system of poor quality will inevitably result in counting errors; In addition, accessories such as the quality of the battery, the valve will also directly affect the quality of the water meter, and the quality of these accessories in our country is currently not satisfactory. 

 The inherent design of these systems and quality, however hard, with such a meter as a basis for metering and charging directly bound to lead to endless trouble. 
 Measurement and Management out of control 
 In addition to the lack of technical, management confusion is also the impact of a bottleneck in the development of electronic smart meter. Harbin and Yinchuan case, there are manufacturers received the money to install after the leave, water damage no one to solve the problem. Hongwei analysis, tables, lines, equipment ownership and management of independent and decentralized, water, electricity, gas, property companies, developers, manufacturers of the respective responsibilities, rights, benefit relationship is not clear, resulting in over shelf life unable to implement the maintenance fund, resulting in the lack of timely maintenance and repair, users lose their protection. 

 On the other hand, water, electricity, gas is a national compulsory certification of measuring instruments, However, due to lack of technical standards, the verification by the institutions of the first verification of the meter reading system currently only stay in the ordinary mechanical measurement of the performance level of the test pulse table rather than the overall test of the system. But the actual meter reading system, the measurement functions required by a table, line, system equipment interaction with in order to achieve. 

 Li Hongwei, to solve the measurement accuracy and reliability of electronic smart meter system, the technological breakthrough is the premise. She believes that in recent years developed a direct meter reading and meter reading system, the feasibility and applicability of the advantages of this system or for the promotion and application of the electronic smart meter system to provide a good solution. 

 Management, Harbin Municipal Academy of Social Sciences, Professor the Donghong Yang suggested that the Government should play a leading role, on the one hand, should develop appropriate policies to be great support, clear all the relevant departments Zequan Li; the other hand, the implementation of market access mechanism, strict control, the implementation of strokes tender require the successful manufacturers and pre-paid part of the margin, strengthen supervision and management during the warranty period, if the manufacturers disposable tube, this part of the margin used to repair problems with the water meter to ensure the smooth implementation of the project.
