Abstract - The current study, titled "Continuous Water
Distribution Network Analysis Using Epanet Software in Ambaji: A Case Study of Ambaji," was conducted with the express goal of effective design, development, and analysis of water distribution networks and systems using EPANET software. The current data on the water distribution system was obtained from the Ambaji taluka Panchayat for this investigation. Three methods were used to forecast Ambaji's population for the following three decades: Arithmetic Increase Method, Geometric Increase Method, and Incremental Increase Method. The expected population's water requirement for the following three decades was also calculated. The elevation of nodes and pipe length were recorded for 148 nodes and an equal number of pipes using a Google Earth image of Ambaji. The findings of data analysis in EPANET Software revealed that there is less head loss, which is critical for maintaining the constant pressure required for Ambaji's continuous water supply system. Key Words: EPANET 2.0; Pipe Network; Water Supply; Water Demand; Population Forecast, Google Earth Image, elevation of nodes, length of pipes
1. INTRODUCTION In India, population distribution is influenced by water availability. It is vital to deliver the requisite water amount through the effective design of pipe network to fulfil the increased water demand due to the growing urban population. The necessary pressure through a distribution network is the most critical task in distributing desired water quantity to individual consumers. Each location in the distribution network must be provided with a specific amount of water flow with all of the appropriate specifications. In most Indian towns, water is only available for a few hours each day, pressure is inconsistent, and the water is of dubious quality. A pipe network system's job is to deliver water at the right pressure and flow. Though pressure is lost due to friction on the pipe wall, the amount of pressure lost is also dependent on the water demand, pipe length, gradient, and diameter. The pressure–flow relationship is explained by a variety of well-established empirical equations, which have been incorporated into network modelling software packages. As a result, while building a pipe network, the primary goal is to achieve appropriate pressure at the supply point in © 2022, IRJET

order to deliver the required amount of water to the user. The intended street plan and topography are often used to develop a water distribution network. The modeller simulates flows and pressures in the network, as well as flows into and out of the tank, using commercially available software. Ambaji has been chosen to analyse and investigate a network of piped water supply systems, which is done while considering a 24-hour water supply system to determine pipe pressure, velocity, and water age, among other things.
2. Study Area Ambaji is a town in the danta taluka of the Banaskantha district of Gujarat, India. It is located at 24.33°N 72.85°E. At a height of 480 metres, it is the highest point in the area (1,570 ft). It is surrounded on all sides by the Araveli Hill Range. Ambaji is around 15 km2 in size. Ambaji enjoys all types of weather. Summers are hot and humid, with high winds and temperatures ranging from 26 to 46 degrees Celsius. In the winter, the temperature ranges from 6 to 36 degrees Celsius. The average rainfall during this cold time is 15 to 30 inches; during the monsoon season, the average rainfall is about the same as in the winter, with some heavy rains. The weather at Ambaji is pleasant all year because it is situated at an altitude of 480 meters.
3. METHODOLOGY 3.1 Justification for the use of EPANET The EPANET software, developed by the United States Environmental Protection Agency, was chosen since it is free on the internet and is intended for general public and educational usage. It is capable of analysing an infinite number of pipes and tanks. In both industrialised and developing countries, EPANET has become a popular tool for studying complicated and basic water distribution networks. EPANET is a computer programme that simulates hydraulic and water quality behavior in pressurised pipe networks over a long period of time. Pipes, nodes (pipe junctions), pumps, valves, and storage tanks or reservoirs make up a network. The water flow in each pipe, the pressure at each node, the height of water in each tank, and the concentration of a chemical species are all tracked by EPANET. EPANET is a research instrument that will help us better understand the movement and destiny of drinking water elements inside ISO 9001:2008 Certified Journal
