In early August 2026, Mexican authorities reported widespread water service shortages. Local agencies such as CONAPA in Nuevo Laredo and municipal officials in Piedras Negras responded to citizen complaints by repairing drains and leaks and installing new infrastructure. State and federal bodies advanced large-scale projects, including the “Agua para Colima” aqueduct intended to double potable water for 240,000 residents, and upgraded technology in Ayala to speed service requests. Legislative actors urged Conagua to improve rain-season preparedness, while reservoir levels in Hidalgo rose to 87.5% capacity.

A few days later, reporting highlighted systemic governance problems behind the shortages. In San Luis Potosí, the privately-run Aquos El Realito consortium was blamed for 73 system failures since 2021, leaving dozens of neighborhoods without water for hundreds of days. In Torreón, the municipal water agency SIMAS reported a massive fiscal deficit of 2,081 million pesos, raising concerns about mismanagement. 

Recent developments indicate that industrial and commercial sectors are also struggling with poor water quality, including contaminants such as arsenic and lead, alongside inefficient wastewater treatment processes.
