Abstract


Water distribution is a critical system that involves engineered hydrologic and hydraulic components to provide water supply to a continuously growing population. Ensuring a sufficient and uniform water supply through a well-designed network is essential to meet the increasing water demand. The present study focuses on analyzing the water demand of the public water supply to facilitate effective planning, development, and operation of water supply and distribution networks. The main objective of the study is to analyze the existing water distribution network at Variyav Headwork using the Environmental Protection Agency Network Evaluation Tool (EPANET). To conduct this analysis, various data points are needed, such as the population of the area, water demand, distribution network layout, and water tank information. Additionally, details regarding the length, nodes, and diameter of the pipes are essential for the analysis. These data are input into the EPANET software to perform analyses related to pressure, head loss, and elevation. The results of the analysis provide valuable information on pressure and elevation at different nodes and head loss along various pipes in the network. By comparing the results obtained from the EPANET with actual data, the study aims to achieve an improved water distribution network at Variyav Headwork. Therefore, in the overall conclusion, the modeled result outperforms the actual data in terms of flow and velocity, where the coefficient of determination (R2)is 0.924 and 0.986, and the correlation coefficient (CC) is 0.855 and 0.973, respectively. In contrast, the modeled head loss is significantly different with respect to the actual data output; R2 is 0.219, and CC is 0.048. Therefore, we can say that the model satisfactorily simulated the flow and velocity and significantly reduced the head loss to 66.46 %. Hence, the insights gained from the analysis will aid in making informed decisions for enhancing the efficiency and reliability of the water supply system.
