Abstract

b hammerer -system-messtechnik, Golgathaweg 1, 9020 Klagenfurt am Worthersee / Aust ria Abstract Due to the change in water management from construction of new to rehabil itation of existing networks strategic rehabilitation management becomes more and more important. To deal with the upcoming rehabilitation demand in times of limited public budgets the identification of areas with high priority for rehabilitation is n ecessary. Consequently this paper shows a priority model which aids in identifying this areas where rehabilitation is not only technically necessary but also economically recommendable. This model is applied on a medium sized case study to compare a prioritization based on different yearly rehabilitation rates. These results are compared with fixed rehabilitation rates. © 2014 The Authors. Published by Elsevier Ltd . Peer -review under responsibility of the Organizing Committee of WDSA 2014.
