A comprehensive analysis of the water distribution network by using waterGEMS software

Abstract

Water is essential for various human activities, and the water need has dramatically increased with population growth and lifestyle changes. This increased demand underscores the importance of sustainable and efficient water management strategies. This study aimed to create robust, efficient systems to meet growing communities' current and future water needs. WaterGEMS software was used to identify high- and low-pressure zones in junctions and assess water flow velocity in pipes to evaluate hydraulic performance. The results showed considerable differences in water demand, pressure, elevation, and hydraulic grade at various intersections. The minimum and maximum demand of 1.0 L/min and 19.0 L/min were found at J-2 and J-31, respectively. The elevation varied from 33.78 to 67.38 meters, with the lowest at J-20 and the highest at J-31. Hydraulic grade ranged from 39.40 to 110.04 meters, with the weakest at J-30 and the highest at J-41. Furthermore, the multi-linear regression model constructed to forecast head loss in the water distribution network had significant coefficients and an R-squared value of 0.965, indicating an excellent match to the data. All coefficients had significant p-values (p < 0.05), indicating the model's reliability.
