The need to attend water demand is associated with climate, social and economic uncertainties, increasing the supply costs. Besides, most water supply systems are no longer able to meet increasing demands, resulting in the need to include nonconventional water sources. Previous work applied simulation and optimization techniques through Dynamic Programming (Fraga et al. 2017), Mixed-Integer Programming (Beh et al. 2014) and Genetic Algorithms (Zhang and Babovic 2012) for expansion of urban water systems. This paper proposes a multistage modelling approach to define operation and expansion strategies that reduce the supply costs under risks of water shortage, incorporating reservoir operation and alternative sources. Besides, the impact of climate uncertainty on the system expansion costs will be assessed as well as the efficiency of incorporating alternative sources. The method is applied in Fortaleza Metropolitan Region (FMR), Brazil. FMR consists of eight storage reservoirs and transmission canals that transfer water from the Jaguaribe basin, where is located the largest reservoir of the state (6.2 billion m³). Rainfall variability and recurrent droughts reduce the reliability on the system, that is in a stage of insufficient adaptation to urban and industrial activity growth.
