Water in Selangor is getting scarce, yet it is the key to its economic development. A fast-growing population and expanding industrialization in the state creates demands for new water sources and innovative management of water resources and services. The goal of this study was to calculate the impact on the supply—demand gap for the city and industry sectors in Selangor by the year 2050. To achieve this, two main simulations involving groundwater application using the Water Evaluation and Planning (WEAP) model, this, integrate an economic optimization model and a hydrology water management model. First simulation involves business as usual scenarios while the second incorporates the water saving measures into the simulation via the demand side management (DSM) analysis. Both simulations were carried out in the Selangor and Langat catchment as both catchments represent the main catchments for the state of Selangor. Such detailed simulation and inclusion of previously unaccounted for factors can help to create awareness of potential future problems, inform water practices, and suggest management alternatives. Results show that with the groundwater as an alternative resource and proper water saving measures, water deficit within Selangor can be significantly reduced.
