Abstract

Understanding hydraulic performance of water distribution system is crucial for sustainable management of a water supply system. In this paper, a case study of hydraulic performance was evaluated using WaterGEMS hydraulic model integrated with GIS at Tulu Bolo town. The WaterGEMS hydraulic model was calibrated (R2=0.93) using measured data at 10 randomly selected nodes. Results of the analysis show that 92.6% of nodes reached optimized pressure ranging between 15m to 70m and about 1.27% are under permissible pressure while the remaining nodes have above the permissible pressure. The velocity of water in the pipes of the distribution system were found to be within the standard range from 0.2 to 2m/s which covers 82.7% (162 out of 196 pipes). Hence, the implementation of the WaterGEMs hydraulic model integrated approach with GIS enabled to estimate the pressure and velocity of the system with better accuracy and this will be helpful for sustainable management of the water distribution system.
