Decision support for sustainable urban drainage system management: A case study of Jijel, Algeria

This paper aims to develop a methodology to support the sustainable management of Urban Drainage Systems (UDSs) in Algeria. This research is motivated by the various difficulties that the National Sanitation Office (ONA) has in managing this complex infrastructure. The method mainly consists of two approaches: the top-down approach and the bottom-up approach. The former facilitates the identification of factors related to a sustainable UDS, the development priorities and the criteria available to managers. The latter assesses UDS performance using the weighted sum method to aggregate indicators or criteria weighted using the Analytical Hierarchy Process (AHP). The method is demonstrated through its application to the UDS in the city of Jijel, Algeria.

► We develop a methodology for assessing the urban drainage system sustainability.
► The method mainly consists of two approaches.
► The first approach facilitates the identification of criteria and indicators.
► The second approach assesses the performance of the Urban Drainage System (UDS).
► This methodology provides a set of indicators for operational applications in UDS.
