The Bezein town is provided with a 150-millimeter diameter main pipe diverted from a 300-millimeter diameter pipeline that supplies drinking water for Shiraz city.
The WaterGEMS is multi-platform software which can model hydraulic and water quality of water distribution systems with the options of advanced interoperability, geospatial model-building, optimization, and management tools. The network was simulated with WaterGEMS software. In this paper, the Bezein water distribution network, located in west of Shiraz, Iran, with a total area of 77 hectares and the occupied area of 34 hectares, with 1907 connection and population of about 7, 600 was selected as the case study. A high quality water distribution system should consist of some main features including: provide acceptable water quality that should not get deteriorated in the distribution pipes network supply water at all the intended places with sufficient pressure head and sufficient amount of water during firefighting be designed in a way that no consumer experiences water supply shut-off during maintenance of any part of the system and also contain fairly watertight to reduce losses due to leakage. Indeed, the main goal of construction of a water distribution system is to effectively deliver fresh drinking water to consumers with appropriate quality, quantity, and pressure over time.
Analysis of a water distribution network means that the hydraulic characteristic of a water suppling network should be evaluated to test the efficiency of the water supplying network in delivering water to the determined locations. Careful analysis of urban water supply systems has been much highlighted than before due to water scarcity and water crisis. Analyzing water distribution networks is very important under deficiency of fresh drinking water.
