Abstract
Many studies showed that the US and Canada's infrastructures are deteriorating and are approaching their projected service life. Statistics Canada (2008) stated that wastewater treatment assets have passed 63% of their useful life in 2007, the highest ratio among the five public infrastructure assets. Wastewater treatment plants failures could have severe adverse impacts on the environment and the human health. A well structured decision support system (DSS) for Wastewater treatment plants (WWTP) will help to optimize and manage the performance of these aging facilities within municipal available budgets. A DSS framework for WWTP is developed based on WWTP condition rating index (CRI). Deterioration curves framework for WWTP main infrastructure elements is developed using the ANN technique. The cost of WWTP maintenance alternatives is the objective function used in the optimization phase constrained by the minimum thresholds of the CRI of different WWTP elements.
