Design of Water Transmission System With Pumping

EasyChair Preprint no. 2768

Abstract

As population increases, city grows extensively which leads to increase in demand of water for domestic, irrigation and industries. Also as the lifestyle of society is changing, they are getting more concerned about hygiene. So, it is duty of authorities to find nearest source of water, treat, store and use it optimally. This requires well designed water transmission and distribution system for providing treated water to consumers. Present study is related to the water transmission network i.e. flow of water from water treatment plant to elevated service reservoir. Main objective of this study was to determine optimum cost of the network. Here, the four reservoir system was considered with low head of source reservoir and higher heads of receiving reservoirs. Dynamic program was used for optimal design of water transmission network involving pumping using the Hazen-Williams equation. Here, the diameter equation was used for assuming initial value of diameter for pipes. Various values of diameter (on higher and lower side of calculated diameter) at an interval of 25 mm were considered and its effect on overall cost of network was analyzed. By using dynamic programming, the set of diameters which gave minimum cost of the network was considered as the optimal solution. Design process helps to identify head of service reservoir and diameters of pipes. The necessary cost data was taken from Maharashtra Jeevan Pradhikaran, Amravati for the year 2019-20.

Keyphrases: Four reservoir system, Hazen-Williams equation, optimal design, optimum cost, Transmission network.
