| چکیده | ||
| Traditionally, the focus of many urban decision-makers has been on the expansion of city infrastructures, while management of valuable assets within the existing aging infrastructure is gaining more attention. Consideration of social developments, conflict criteria, risk management, sustainability, and resiliency has further introduced holistic approaches in Water Distribution Networks (WDN) management. Here in this research, a WDN, aged more than 30 years and serving a population of around 20000 people, comprising three municipal districts in a municipality of Iran, has been selected as the case study. Despite the limitations of comprehensive data, it is evident that the network suffers from two major issues, namely the high rate of leakage and frequent pipe failures. The existing condition of the WDN has been simulated using the EPANET software linked to a designed MATLAB suit. The simulation was based on three main modelling processes: Pressure Dependent Demand for water consumption, Poisson Process for pipe failure, and Integrated Model for pipe water leakage. Based on the calibrated results, risk maps of water leakage and pressure/pipe failure of the WDN were developed, and areas with assets that had high priority for intervention were identified. Multiple practical management methods, such as pressure management, pipe renewal, and designing district metering areas (DMA), are proposed to decrease the severity of the detected problems | ||
