1. The key to urban water supply safe water quality of urban water supply is social circulating water scale largest in the source link, involving water safety aspects and links, especially directly related to peoples health safety drinking water protection technology to improve the water supply, water purification, transmission and distribution together constitute the security control and water quality protection. So urban water supply safety, water quality control is the key. 2. People-centered water content of the city in dealing with population, resources, environment and the relations between socio-economic development process, people-oriented is the core of economic development fundamental purpose is also well itself healthy development, improved quality of life, improved environment. The water supply is safe for human rights, not only for the urban water supply volume requirements, more stringent requirements have to confront, especially in the increasingly serious water pollution, water shortage situation base to widely occur in relatively water-rich south many cities. Chinas vast consumer demand for water quantity, water quality is getting higher and higher, people want to know the drinking water quality of exactly how strong demand into line with standards and the standards of developed countries of the World Health Organization, and regularly publish the citys water supply requirements water quality. This government and all kinds of locks in the difficulty of monitoring the quality of water has increased, increased job responsibilities becomes large, and how actively adjust the management system and operation mechanism, how to strengthen the supervision of the water quality of urban water supply, how to use modern technology to monitor so a series of water quality issues has become imminent, the system must be committed to solve the problem. 3. drinking water standards is not an absolute standard drinking water standards is not an absolute indicator, but to combine their level of economic development and peoples health in the region requires the level of benefits is determined by analyzing a investment, so the world wHO issued the "guidelines for drinking water quality", rather than international standards, countries, regions can be explained based on economic development, investment and benefit a person to develop appropriate standards. Implementation of the World Health Organization in my countrys Hong Kong "Guidelines for Drinking Water Quality" Macau implementation of the EUs "quality of instruction" execute "drinking water health standards" (GB5749-2006) inland. Various standard-setting related to the implementation of the local political, economic, environmental and so on. 4. Urban water supply security of several key aspects of the current situation of water supply equivalent to the security situation during the period from 1976 to 1994 the United States. The United States took place in a total of nearly 20-year period414 accidents from urban water supply, water purification plants which process runs defect 388, accounting for 93.72 percent, the number of cure 42 million people, untreated groundwater nine accidents, accounting for 2.15%, the number of treatment 7 thousand people, the pipe network 7 runs defect, accounting for 1.58%, the number of treatment nearly 80,000 people, but only about 3 other reasons. Visible urban water supply safety is the most important, first, strict control of water treatment processes running water, and can effectively control water quality, protect the water supply safe, so to achieve system stability and reliable operation of process water, water purification plants factory long-term stability compliance is the main control of urban water supply security; second, in the process of distribution of water in the pipe network for water quality safety control.
