Source of Water in San Andrés, Colombia
Tap water in San Andrés mainly comes from groundwater drawn from the island’s freshwater aquifer through public wells. Because the island has no permanent rivers, groundwater is supplemented by seawater desalination.
Rainwater collection and treated water from desalination plants also contribute to the public supply, especially during periods of high demand or limited groundwater availability. The water is treated and distributed through the island’s municipal aqueduct system.
