In late October, residents in Medellín and surrounding municipalities, including Itagüí, La Estrella, and Sabaneta, reported yellow or brown water from their taps. Empresas Públicas de Medellín (EPM) attributed this discoloration to repairs on a 36-inch primary water main in the Envigado area, which affected supply from the La Ayurá treatment plant.

By early November, the focus shifted toward water conservation efforts in the Valle de Aburrá. Household water savings reached over 60 percent of the targets set by EPM, aided by rainfall and improved consumption habits. While systems such as Piedras Blancas, La Fe, and Riogrande II showed progress, EPM warned that isolated rains might not fully recover reservoirs against the El Niño phenomenon. The utility company maintained a period of scheduled water rationing during this time, with decisions on its continuation pending.
