Quality of Service in Irrigation Distribution Networks: Case of Palos de la Frontera Irrigation District (Spain)

Abstract

A methodology based on indicators was developed to study the quality of service provided in irrigation distribution networks. The indicators were divided into network descriptors and operational indicators, some calculated periodically and others in real time. The methodology has been applied to the Palos de la Frontera irrigation district (Spain) using information on flows, volumes, and pressures collected via remote metering devices linked to a central computer database. The results showed that the service provided in the district has good quality in terms of flow adequacy, distribution efficiency, and pressure and supply reliability. Problems dealing with the remote control system have been identified. Categories for the indicators have been established, studying the percentage of control points included in each and their probability of occurrence. The methodology is useful to determine the main problems in a distribution service and areas in the network which need improvement.
