Urban water is known as critical sector of urban environments which significantly impacts the life quality and wellbeing of reinstates. In the context of developing sustainable urban drinking system it is critical to analysis network events and develop sufficient systems of water supply. In following this objective, the current study aims to propose an efficient approach for Geospatial based urban water network events analyze and determine the optimal location of urban drinking water relief posts in Zanjan. For this goal, first, we prepared and preprocessed various predisposing variables such as water storage sources, pump stations, traffic density, population density, road network, land use, subscribers, areas with higher water pressure, and accident-prone areas for analyzing the urban water network events and determining the optimal location of urban drinking water relief posts. We then applied an integrated approach of analytical network process (ANP) and deep learning convolutional neural network (DL-CNN) data-driven methods to locate the optimal place of urban drinking water relief posts. Finally, intersection over union and accuracy assessment were employed to evaluate the performance of the results. Our findings show that the DL-CNN performed well with the accuracy of 0.942 than the ANP (0.895) for determining the optimal location of urban drinking water relief posts. The results indicate that the most suitable places for building a relief post are in the center of the city and its surrounding areas might not suitable due to barren lands and sparse population. The results of the study also reveal that areas 5 and 3 are at high risk from the number of urban water network incidents perspective, which require the construction of urban water relief stations.
