VERDUZCO, Vivían; GARATUZA, Jaime  and  DIAZ, Salvador. Prioritization of Needs to Replace Piping Using GIS and Multicriteria Evaluation. Tecnol. cienc. agua [online]. 2015, vol.6, n.1, pp.99-120. ISSN 2007-2422.

Although the deterioration of infrastructure directly affects the physical efficiency of systems, it is financially impossible to renovate entire systems. This situation requires prioritizing actions to increase the efficiency of potable water networks. One of the primary components affecting the physical efficiency of water supply systems are pipes, which are affected by a series of parameters related to the hydraulic behavior of the system (age of piping, material, roughness, pressure, demand and diameter, among others). The development of a hydraulic simulation model using the Pipelinenet system in ArcGis provides real-time information about conditions and risks associated with potable water, considering the spatial component, which determines the importance of each element in the network according to its location. This facilitates a multicriteria analysis of factors that are endogenous and exogenous to piping, for consideration by authorities of operations entities in order to prioritize activities to rehabilitate, replace and expand the system. The present work is intended to integrate the advantages of a geographic information system (GIS) into a multi-attribute analysis of the urban potable water distribution system of Providencia, Sonora, Mexico, and to propose a decision-making method to support the planning and control of the potable water network.

Keywords : Hydraulic model; planning; water distribution systems; rehabilitation; decision making.
