摘要

Nanded City, Maharashtra State, India’s water distribution network (WDN) was originated in 1974 to serve to a population of 0.4 million people. In 1986 and 2001, it was extended twice. Due to the extended portion and increased population, required pressure and discharge are not available, especially at the tail end of the network. Therefore, in order to evaluate the pressure and discharge capacity expansion analysis of WDN design is required. The main purpose of this work is to examine the WDN for existing pipe diameters and to design for optimized diameters to fulfill given hydraulic constrains. This paper shows the analysis and optimized design of the WDN of Taroda the north part of Nanded City. The WDN consisting 1737 pipes and 1306 nodes is developed in WaterGEMS. Integrated tool Darwin Designer is utilized for optimized design, providing detailed hydraulic parameters like pressure head and flow. Following the analysis, the WDN is redesigned by making objective function aimed at maximizing hydraulic benefits. The design results show effective optimization of pipe diameters with satisfactory performance outcome. The pressure at nodes was found satisfactory except for few nodes at the tail ends in the network. This design selects available pipe diameter as input while the design gives excludes diameters 150 mm, 200 mm, and 300 mm as per given requirements for given constraints.
