Determining physical and operational factors influencing pipeline leakage location pattern in water distribution networks using spatial poisson point process

Abstract There are four pillars in leakage management strategy for water distribution networks, consist of pressure management, speed repairs, active control, and asset management. Leakage can be managed by applying the right combination those factors strategy. This study conducted Malang City, East Java, Indonesia. The that influence physical loss system analyzed focusing on operational parameters. data this spatial quantitative data. Poisson point process is used as approximation. From analysis, it found pattern pipeline location categorized inhomogeneous poisson process, with two types intensity area. Based results parameter estimation, high-intensity area affected time pipe diameter, length ratio, supply deterioration ratio but not hydraulic energy demand. While low-intensity influenced demand repairs.
