Abstract -The present study shows the remodeling of
design is based on the proposed street plan and the topography. Using commercially available software, the modeler simulates flows and pressures in the network and flows in and out to/from the tank. In the present work, Gabbur Zone of Hubballi city has been selected to analyses and study network of piped water supply system which is done considering 24×7 water supply system to know pipe pressure, velocity, water age, etc.
existing network and also designing the water distribution network using a programming tool, which performs the extended period simulation of hydraulic and water quality behavior within the pressurized network of pipes called EPANET. A network comprises of pipes, nodes, pumps, valve and storage tanks or reservoirs. EPANET estimates the flow of water in each pipe and the pressure at each node, EPANET is designed to be a research tool for improving the movement of drinking water within distribution network. This papers demonstrates the use of EPANET for the hydraulic study of the distribution network.
2.STUDY AREA Hubblli is situated at 15° 20’N latitude and 75° 13’E longitude and Dharwad is situated at 15°25’N latitude and 75°E longitude. The altitude of the twin cities, Hubballi- Dharwad, varies from 764 m to 593m with Dharwad being at a higher elevation. The twin city is located along National Highway No. 4 between Pune and Bengaluru cities and is at a distance of about 400 km from the State Capital, Bengaluru.
Key Words: EPANET, Analysis and water distribution network.
1.INTRODUCTION In India, water availability controls population distribution. To meet the increased water demand due to growing urban population, it is necessary to provide the required water quantity through the efficient design of pipe network. The most important task in distributing desired water quantity to individual consumers is the necessary pressure through a distribution network. It is essential that each point of the distribution network be supplied with a certain quantity of water flow with all the desired parameters. The water supply in most Indian cities is only available for a few hours of a day, pressure is irregular, and the water is of questionable quality. The function of a pipe network system is to supply water at required pressure and flow. Though, pressure is lost by the action of friction by the pipe wall, the loss in the pressure is also reliant on the water demand, length of the pipe, gradient and diameter. A number of well established empirical equations explain the pressure–flow relationship and these have been included into network modeling software packages. Thus, while designing a network of pipe system, the primary aim is to achieve adequate pressure at supply point to receive required quantity of water to the consumer. Conventionally a water distribution network

The total area of the city corporation area is 202.28sq.km covering 45 villages. The city is divided into 67 wards of which wards 1-22 come in Dharwad and 2367 come under Hubblli and Gabbur zone have present population 19,567 area 1.13sq.km.
3. METHODOLOGY The study area comes under the urban settlement. The projected population for the year 2045 is estimated to be 35085. The water demand of 135L/C/D has been used in the present work as per the standards of the Central Public Health Environment Engineering Organization (CPHEEO). The procedure followed for remodeling of existing water distribution network is as mentioned in the following paragraph. Step 1: Import network file with the help of EPACAD software where network placed in a text file. Step 2: Edit the properties of the objects that make up the system. It includes editing the properties and entering required data in various objects like links, node such as diameter, length of pipe, elevation, base demand etc respectively.
