Investigating the Pattern of Water Consumption in Public Places (Case Study: Sistan and Baluchestan University)

Sistan and Baluchestan province is one of the water-scarce regions of Iran with hot, dry climate and very little rainfall, and water shortage is one of the most common problems in this province. Sistan and Baluchestan University is one of the water consumers in the region, which spends a lot of money annually to water consumption. In this regard, a study was conducted to investigate water supply facilities and water consumption in the dormitories of Sistan and Baluchestan University. As an example, dormitory No. 5 was selected from the Efaf and Hejab Dormitory Complex of Sistan and Baluchestan University and field studies and objective observations were performed. The results of the observations indicate problems such as broken and old valves and their connections, old heads, improper siphons, improper use of water by people living in dormitories and improper irrigation of green space. The above are important factors in wasting a large volume of water. In this study, replacing dormitory valves with lever valves was suggested as the main solution. In order to investigate the effect of the proposed solution, the dormitory water supply network with two types of normal and lever valves was simulated with WaterGEMS software. The simulation results showed that the use of lever valves reduces water consumption by about 23% and can have a significant impact on reducing water consumption and water costs. Therefore, it can be concluded that replacing lever valves, while being practical and economical will significantly reduce water consumption.
