Mexico City's water system is in poor health, with 1/5 of residents lacking daily access to water
Mexico City, a sprawling metropolis of nearly 22 million people and one of the world's biggest cities, is facing a severe water crisis. The city's water system is in poor health, with around 20% of residents lacking daily access to water. This is due to a combination of factors, including geography, chaotic urban development, poor planning, urban sprawl, leaky infrastructure, and the impacts of climate change. The city's interim mayor, Martí Batres, has denied the existence of a water emergency, but experts warn that the situation is critical and that Mexico City could be barreling towards "day zero" when water stops flowing from the Cutzamala system altogether.
The groundwater in Mexico City is quickly vanishing due to over-extraction, and a key reservoir has gotten so low that it is no longer used to supply water. The city's reservoirs, which supply the Cutzamala water system, have fallen to historic lows of around 38% capacity due to abnormally low rainfall in recent years. This has led to significant restrictions on the water pumped from reservoirs, with authorities warning of major water shortages across huge swaths of Mexico City until the rainy season begins in June.
The water crisis in Mexico City has set off a fierce debate about the possibility of reaching "day zero." While politicians have downplayed the severity of the situation, water experts and scientists warn that the city could run out of water if no changes are made. Tamara Luengo, a water expert in Mexico City, states that the water situation is at a critical level and worsening. Christian Domínguez Sarmiento, an atmospheric scientist at the National Autonomous University of Mexico (UNAM), agrees, noting that several neighborhoods have suffered from water shortages for weeks, with months left until the rains start.
To address the water crisis, Mexico has implemented several measures. The Mexican government has created water reserves in nearly 300 river basins throughout the country, representing 55% of Mexico's surface water. These reserves will guarantee water supplies for 45 million people for the next 50 years. Additionally, Mexico has invested $46 million in water sanitation projects for the Tijuana River, including upgrades to Pump Station CILA and infrastructure repair projects to reduce wastewater flows. Mexico has also developed a new regional plan with the State of Baja California to address transboundary pollution flows and reaffirmed its commitment to funding wastewater treatment, collection, and reuse projects.

The Mexican government has created water reserves to protect the country's water supply for the next 50 years
Mexico has been facing a water crisis, with 57% of its population lacking access to safe water. The country has been dealing with water scarcity, droughts, inadequate drinking water quality, and wastewater treatment issues. In 2018, the Mexican government took a significant step towards addressing this crisis by creating water reserves to protect the country's water supply for the next 50 years.
On June 5, 2018, Mexico's then-president, Enrique Peña Nieto, signed a series of decrees to establish water reserves in nearly 300 river basins across the country. These reserves protect 55% of Mexico's surface water and are expected to guarantee water for 45 million people for the next five decades. The creation of these reserves is the result of a collaborative effort between WWF-Mexico, CONAGUA (the country's national water commission), and the Gonzalo Rio Arronte Foundation, supported by the Inter-American Development Bank (IADB).
The team behind the reserves has spent the last 12 years meticulously mapping Mexico's rivers and scientifically determining the water volume required to sustain each river's ecosystem and meet human needs over the next 50 years. This long-term vision ensures that Mexico can proactively manage its water resources and prevent a future without water. The reserves are located in regions where water is not overexploited, allowing for greater biological diversity and a preventative approach to water conservation.
Mexico has also been working closely with the United States to address transboundary water pollution along the US-Mexico border, particularly in the Tijuana River Valley. Both countries have recognized the importance of reducing pollution levels and improving water quality in the region. Mexico has invested $46 million in water sanitation projects, including upgrades to Pump Station CILA and infrastructure repair projects to reduce wastewater flows. The US and Mexico have agreed to coordinate on projects and funding sources related to wastewater collection and reuse, demonstrating a shared commitment to finding lasting solutions to transboundary pollution.
In addition to its efforts in creating water reserves and addressing transboundary pollution, Mexico is also tackling water challenges in its cities, especially Mexico City. The city has faced issues with an outdated water system, rapid population growth, and the impact of climate change. Experts emphasize the need for reducing leaks, saving water, and finding new sources to ensure the sustainability of the water system.
