Abstract
One of the most crucial decisions for water and sewerage companies is how to strategize network renewal activities. Any misstep in this area can result in wasted allocated funds and the emergence of issues related to water distribution networks. Consequently, it is essential to make the most informed decisions possible. Planning for the renewal of water distribution networks typically considers factors such as events and failures of network pipes, along with water demand and network development. However, the analysis and evaluation of these factors within water and sewerage companies often lack precision, leading to ineffective planning for renewal activities. This research aims to enhance the planning of the water distribution network renewal in Qamsar city, Kashan, by analyzing data on the network's historical events from 2019 to 2024. To achieve this, a Strategic Asset Management model was developed to analyze failures within the Qamsar network, identifying the most significant indicators of events in the water distribution network of Qamsar city. The results demonstrate that, using the SAM model, it is possible to assess the profile of historical events, including the number, location, and type of events, the failed equipment, the repair works, pipe size and type of pipe that failed the reason of the event, the covering of the event location, and its network pressure. Based on this assessment, the renewal strategies of the water distribution network could be determined. The SAM model developed in this research can be used to plan the renewal of the water distribution network.
