Research And Evaluation On Regulative Mode Of Water Supply System In Small Towns

The explosive growth of small towns is playing a no replaceable role in activating local economy growth and flourishing market. However, compared to the requirement of town planning, the whole level of construct actuality for water supply establishment is low-lying in small towns, dynamic of water supply is meta-high and leakage is also severer. These problems not only cumber benign running of water system for small towns, but it also restrict the economic and social development of small towns.In order to accelerate construction of supply equipment of small towns, besides the augmentation of fund in construction of supply equipment of small towns, combined to characteristics of water supply in small towns , reducing dynamic , decreasing investment and adopting a more economical, more scientific and more proper regulation mode of water supply is one of the effective measures of confineable development of small towns' water supply system. Water using in small towns have lots of characteristics, such as small scale, big hour variable coefficient, variety range of low and water press in pipe network is great and so on. So it is very important to establish regulative establishment of water supply system in small towns. Therefore, studying regulative mode for small towns has important practical sense for promoting perfect and development of water supply in small towns.Firstly, aiming at the characteristics and application condition of several regulation modes of water supply, several regulation modes that are suited to small towns are presented; according to the design of regulation building, the selection of geographical position, useful capacity and the number must meet the requirement t and principle, some elements that influences the design of regulation building are analyzed and discussed.Secondly, aiming at the characteristics of work condition of different layout forms of water tower (or high-order water chamber) in the pipe network, the transportation and service pipe network are analyzed about economy; combined to the characteristics of small towns, according to economical calibers of various water source pipe network with water tower (or high-order water chamber), dynamic of water tower (or high-order water chamber) in the different layout forms of pipe network are contrasted and analyzed, as a result, the fabrication cost and dynamic of service pipe network with the beginning water towers are higher than the contra positive layout forms of pipe network...
