RESUMO

Water supply is extremely important for the welfare state of society. Many water supply systems have presented operational deficiency due to high increase on the demand or lack of adequate maintenance. The increase of on frequency of the interruption on the water supply has been usual, thus not fulfilling customer expectations for the consumers. High investments are needed to rehabilitate the existing water supply systems aiming at ensuring adequate operational levels. This situation highlights the importance of the development of new methodologies aiming at the rehabilitation of these systems for an adequate operation, within satisfactory technical standard and acceptable costs. Thus, the proposed methodology aims to study rehabilitation alternatives in existing water systems, taking as support a water supply network simulator (SPERTS). In order to consider the multiple aspects on the decision making process about the possible rehabilitation solutions, a multcriterial analysis is used thus, providing an hierarchy of the alternatives found in each case
