Mexico City's Water Supply Hits 81% Capacity: A Decade-Long High

The single most useful takeaway: Mexico City's Cutzamala water supply system is now at 81% capacity, its highest level in a decade, thanks to steady August rains and increased water storage.

What's Changing

The steady August rains have significantly boosted the Cutzamala reservoir system, Mexico City's primary water source. According to data from the National Water Commission (Conagua), the Cutzamala System has experienced 13 consecutive weeks of recovery since the beginning of the rainy season on June 4. This year, the Villa Victoria reservoir, which was around 30% full just three years ago, is now over 78% capacity, holding more than 145 million cubic meters of water.

What It Means for Residents

The increased water storage means that the greater Mexico City Metropolitan Area, which is home to 5 million inhabitants, will see more stable water supply. Conagua's monthly report for August indicated that the Valle de Bravo dam was at 86.58% capacity, the Villa Victoria dam held 78.10% of its capacity, and the El Bosque dam was at 72.98%. These levels are significantly higher than the past three years, when the system was operating at 50.31%, 50.15%, and 36.71% capacity, respectively. The system provides 18% of the water consumed in the area, around 422 million liters daily.

The Cutzamala System has been a critical concern for policymakers, especially during the 2023 drought, which saw the system operating at 36.71% capacity. However, the current volume of water is roughly equivalent to that recorded in August 2017, but storage has steadily increased since then. This year’s data shows that the three dams had increased their level by more than 30 million cubic meters compared to the same period in 2025, significantly helped by five days of heavy rainfall in the Balsas and Lerma river basins.

With reports from La Jornada, Excelsior, N+, UnoTV, and Milenio, the system is on track to reach its maximum capacity for the year by Oct. 31, projecting 98% capacity.

Why It Matters for Expats and Digital Nomads

This water supply improvement is particularly significant for expats and digital nomads living in or currently based in Mexico City. It means fewer water restrictions, less worry about water shortages, and a more stable lifestyle. With a higher water supply, residents can look forward to fewer water rationing periods and more reliable water flow, which can greatly impact daily life, especially for those in the tech industry who rely on consistent water supply for their operations.
