Rosarito desalination plant construction begins in Baja California

Construction has officially begun on the Playas de Rosarito desalination plant in Baja California, a project described by officials as the largest and most modern of its kind in Latin America. The initiative, supported by the Mexican federal government and the state administration, aims to secure water sovereignty for the region and reduce dependence on the Colorado River.

The plant is expected to desalinate 2,200 liters of seawater per second, potentially increasing water availability in the region by up to 45 percent. This infrastructure will serve more than 2.2 million residents across the municipalities of Tijuana, Playas de Rosarito, and Ensenada.

The project involves a total investment exceeding 15 billion pesos. The federal government, through CONAGUA, is contributing approximately 10.5 to 10.7 billion pesos, while the Baja California state government is investing roughly 4.6 to 4.9 billion pesos to complete the distribution network. The facility is expected to be completed by 2029. Officials stated that the project will not result in increased water tariffs for consumers and will include high-efficiency energy systems to manage operational costs.
