Choosing the Optimal Technology to Rehabilitate the Pipes in Water Distribution Systems Using the AHP Method

In this paper the authors intend to solve in a scientific way, using the AHP method, a problem faced by companies in the field of water supply in towns, and choosing the technology of pipe rehabilitation in water distribution systems. This paper presents a case study on the selection of the technology for the rehabilitation of domestic water distribution network in Cluj-Napoca. We used the AHP method in order to rank the priorities regarding the rehabilitation of water distribution network. Based on the study performed, we recommend using the Slipline method for the rehabilitation of water distribution pipes in Cluj-Napoca, Romania. The method presented in this paper may be used for the feasibility studies elaborated for water distribution networks. Also, the AHP method may be correspondingly used for the selection of other types of installations for buildings.
