Optimization of leak detection in drinking water distribution networks using BAT Algorithm: Case study - Bologhine city

The increasing prevalence of water scarcity has emphasized the urgent need for effective management of water distribution systems, particularly in urban areas. To achieve rational management of facilities and ensure long-term customer comfort, water utilities on the worldwide are seeking solutions to find a good compromise to avoid the major problem of leaks in distribution networks. Several techniques exist to address this problem, including pressure modeling of distribution networks, which has become a widely used technique for reducing leak rates and extending the lifespan of installations. This work consists of proposing a methodology for optimizing leaks in a drinking water supply network in Bologhine city using hydraulic models and stochastic methods. Stochastic model namely BAT algorithm was employed to simulate various scenarios of demand fluctuations and pressure changes, allowing us to assess the risk and occurrence of leaks under different operational conditions. The optimization of pressure control was achieved by implementing a strategic pressure management system that dynamically adjusts pressure settings based on real-time demand data and identified vulnerabilities within the network. By employing these methodologies, cities like Bologhine can enhance their infrastructure resilience, reduce water loss, and promote sustainability in urban water systems.
