Design of Water Supply System for Green City

Abstract

In water supply system the function of carrying water is done through well planned distribution system choosing suitable diameter of pipes as it comprises the major investment in the system. Analysis and design of a pipe network system is a complex and time taking work. Now a day’s lot of pipe software is available which can be used suitably for layout and analysis of pipe network system. Working with professional software requires both money and training. Sometimes it is required to design a simple pipe network system for which an easy method will be suitable. In this present project work, a simple method is discussed which can be used suitable for optimal design of pipe networks for the water distribution system. The problem in this report has thus been solved with a view to reduce the total cost of pipe network satisfying the required amount discharge in the outlet. Hardy Cross method has been used for estimating the required discharge in each outlet of the pipe network, and optimization of the system has been done to reduce the cost with the help of Microsoft-excel. We also come across useful software EPANET 2.0 which is a computer program that performs extended period simulation of hydraulic and water quality behavior within pressurized pipe networks. EPANET tracks the flow of water in each pipe, the pressure at each node, the height of water in each tank, and the concentration of a chemical species throughout the network during a simulation period comprised of multiple time steps.
