Abstract The paper introduces an international research project, CARE-S, that deals with rehabilitation strategies for sewer networks. The aim of the project is to develop an integrated tool for functional and structural rehabilitation of municipal sewerage systems. CARE-S is a research project supported by the European Commission under the Fifth Framework Programme. The project’s objective is to establish a rational framework for sewer network rehabilitation decision-making. CARE-S aims to analyse the structural and functional reliability of wastewater networks at minimum cost and disturbance. The ultimate product will be a Decision Support System that will enable municipal engineers to establish and maintain effective management of their sewer networks.

Key words 5th Framework Programme; decision support system (DSS); hydraulic performance; multi-criteria decision support; performance indicators; rehabilitation technology; sewer network rehabilitation; socio-economic consequences; urban drainage system
