Water is definitely the source of life on Earth, will be the lifeblood of urban development. Using the acceleration of urbanization and industrialization in China, water shortages are spreading across the country, water pollution incidents, severe threat to the security of urban water supply. Urban water provide systems from water sources, water therapy plant, water provide network, and so on, rational distribution of water sources, optimal water provide method and assure safety of urban water provide, is definitely an significant topic in urban improvement and construction.




Rational distribution of water to improve water high quality




Protected drinking water is actually a fundamental have to have of human survival, improvement. In current years, because of water pollution water high-quality water shortage in quantity of cities in China is on the rise. Preferred speaking, lack of great top quality water is "tank has water to drink," the tank served low top quality of water is undrinkable. Therefore, sufficient water, water excellent, a very good source is definitely the major guarantee of security of urban water provide.




Before 2010, water provide primarily will depend on the Huangpu River in Shanghai, the Yangtze River estuary chenhang bar two centralized water, which about 81% of water of Huangpu River, would be the primary water supply of your central city water plant. With continued growth of urban water provide in Shanghai, Chen Xing modest reservoir capacity, low salt-resistant ability, effects of water and coastal pollution within the upper reaches from the Huangpu River, two centralized water sources, water quality water scale has been unable to meet the requirements of urban development in Shanghai. Strengthen the water high-quality of Huangpu River,Single-Jet Series Water Meter whilst in search of new water sources, became the essential to solving water supply difficulties.




To this finish, the advance via the incorporation on the upper reaches from the Huangpu River water supply arranging intakes, upper compact and ecological regulating reservoir to improve water high-quality of Huangpu River, and improve its capability to respond to sudden water pollution accident. The Shanghai water provide technique on an expert arranging pointed out, Shanghai urban improvement path of water really should be gradually shifted from the River to the Yangtze River. In this context, Changxing Island Northwest tip of qingcaosha reservoir in to the people's eyes. On 1 hand, grass, Sandy Director Jiang Kou River location, without interference from land pollution, water high-quality, around the qingcaosha region of tidal flat and tidal channels offered, which maximizes the mitigate the effects of saltwater.




In 2011, the second river light salt reservoir to prevent storage ?C project began in Chongming East Sha reservoir marks the Shanghai "upper reaches of Huangpu River, Yangtze estuary chenhang, grass, sand, Dongfeng Xisha" four Headwater Method pattern has taken initial shape. On 1 hand, the 4 water sources can effectively assure the Shanghai water supplies from the effect of water pollution within the upper reaches, however,Oscillating Meter in the salt tide period "linkage, North-South complementarities and Dodge for pressure" to maximize the resolve salinity crisis.




Optimization of water supply technique to ensure water provide security

Safety improvement of water provide technique for water supply, water plant is water "Purifier", water provide pipe network is "Porter". According to the layout of water, divided among Puxi and Pudong, Shanghai Punan, three-four water provide locations, building a total of 202 substantial and little water plants, water is usually safely delivered to households.




At present, the water plant layout is additional adjusted, layout and operation of water provide network has been optimized. Shanghai will build a reliable water supply versatile and affordable layout of water provide network,Multi-Jet Series Water Meter water excellent reaches international sophisticated level "one network slice" the water supply method, powerful protection of Shanghai water provide safety. Water plant construction, gradually expand the scale of water supply in central urban location in Shanghai and also the scope out and strengthen outdated facilities of town water plant, current 202 significant and little water plants grouped in about 43 seats, to kind a water plant, district water performs as a supplement in the center of intensive water provide pattern.
