AbstractAn economic-engineering optimization model known as Baja CALVIN was used to determine the most viable options for water supply to the city of Ensenada and the Maneadero and Guadalupe Valley agricultural regions in the State of Baja California. Agricultural and urban use data, and information on the region’s hydrology and existing hydraulics infrastructure were taken into account to establish 16 water management scenarios that combined water management policies, such as wastewater reclamation for crop irrigation, aquifer and dam recharge, water transfers from the Colorado River (El Hongo-Guadalupe aqueduct), seawater desalination, and aquifer overdrafts. Data on scarcity, scarcity costs, and willingness to pay for urban and agricultural use were obtained. The best economic performance alternatives due to less scarcity costs (4 200 000 $ year) were those in which wastewater reclamation was included, mostly used for crop irrigation. The El Hongo-Guadalupe aqueduct was the second best option, although scarcity costs for agriculture was still high (9 500 000 $ year). Seawater desalination was never economically viable and the model opted for not using this option, although scarcity costs increased to 37 400 000 $ year. Aquifer overdrafts presented the lowest scarcity costs, although it is not a sustainable practice. In terms of water transfers, the Guadalupe aquifer was not used for supplying water for urban demand for Ensenada, and the El Naranjo wastewater treatment plant effluent was key for maintaining agriculture viable, particularly in Maneadero
