Planning and Design Principles of Transmission Line in Water Supply Project

Abstract

Water is an essential substance for human life and living things. It is not substance for the life, but also energy input for agricultural and industrial production. In addition to, it is needed for human daily activities and environment. Water is taken to a place where people need by with transmission lines in water supply project. A transmission line is designed according to requirements, topographic conditions, engineering principles and economic criteria. Transmission lines are large scale projects which planned and projected by public organizations which are DSI, Provincial Bank and Municipalities. Although they are competent and experienced; some problems have been observed in water supply projects such as; lack of future plan, expropriation problem, improper pumping station, incapacity, inefficiency, pollution, poor quality, necessity, inadequate itineraries, too long lines. To avoid these problems, first future development plan for cities should be made and carried out without compromising. Next, the detail study should be carried out for each project from engineering, environmental and economic aspects. In this paper, these issues were examined and discussed to take attention to some important points in planning and designing of transmission line for the application
