The software also gives different alternative optimal design solution considering pipe diameters, pipe material and roughness coefficient based on head dependent analysis. [2.3] Feasibility Analysis of Water Distribution System for Yavatmal City using Water Gems Software:- Shinde Parmanand Bhaskar (2017), A study was undertaken to suggest measures for the improvement to the distribution system, which can easily fulfill the demand for water in the city and can lead to development of the city in near future. The paper presents results of analysis carried out using Bentley systems Water gems for basic design of distribution system which consist of reservoir, pipe network and ESR. Various materials‘ costs can be marked and cost estimation is not considered in this study as it depends on the authority to approve, but PVC cost is the lowest among the all materials and [2.4] Water distribution systems reliability: -A.Gheisi,M.forsyth, et al (2016),this study provides an in depth review of the relevant research literature. This research organized and classified the available techniques into three major categories and discussed which technique should be used depending upon the type of failure. Failure in WDS was classified into mechanical/physical, hydraulic, and water quality failures. Occurrence probability or rates of failure in pipes, pipes failure combination, and criteria to measure reliability were the key factors that affect the WDS‘s reliability. [2.5] A review of modeling and application of water distribution network softwares:- Mandar G. Joshi(2015),This ever increasing demand can be fulfilled by designing efficient water distribution networks based on advance computing systems include modern hydraulic modeling and designing software.This extensive of review softwares for designing and modeling WDN concludes that the choice of design softwares are entirely depends upon the availability of the data, time, financial implications, resources, applicability, compatibility and overall purview of the project. [2.6] Optimal design of water distribution network by using WaterGEMS:- Sajedkhan S. Pathan, et al (2015), stated water distribution network systems are designed to deliver water from a source in the adequate quantity, quality and at satisfactory pressure to all individual consumers. Water distribution network are designed with an objective of minimizing. The overall cost while meeting the water demand requirements at adequate pressures. Water GEMS software algorithm is based on Gradient method gives optimal solution for the design of new as well as expansion of existing water distribution network. The primary variables are flow in the network while other decision variables includes design parameters i.e. pipe diameter, reservoir elevations etc. Head and velocity dependent analysis is used to determine the actual supply form each node to consumers. In this paper CIDCO N-8 a part of Aurangabad city is designed by Water GEMS software. With the help of WaterGEMS software an optimal water distribution network are designed and also helps in achieving objective of minimizing the overall cost while meeting the water demand requirements at adequate pressures for specified maximum design discharge over a long period of time.
