In early 2026, Corpus Christi, Texas, faced a water supply challenge that tested the resilience of one of the United States’ major industrial regions. Reservoirs at Choke Canyon and Lake Corpus Christi fell to just 10% of their combined capacity, the lowest level on record, as the city prepared for a potential water emergency.
Months later, rainfall began to change the outlook. Reservoir levels started to recover, easing the immediate threat of an emergency. However, this episode should not be viewed simply as a crisis that passed. Rainfall helped replenish reserves, but it did not eliminate the vulnerability of a region where industrial activity continues to drive water demand and authorities are still working to diversify supply.
The main lesson from Corpus Christi is that economic growth can outpace the development of water infrastructure. This is a risk Mexico should consider as it attracts investment, opens new industrial facilities and expands its industrial corridors.
The Relationship Between Industrial Growth and Water
For decades, Corpus Christi has been a major energy and petrochemical hub in the United States, supported by investment in port infrastructure, refining, manufacturing and liquefied natural gas (LNG) exports.
According to the U.S. Energy Information Administration (EIA), a significant share of U.S. LNG export capacity is concentrated along the Texas Gulf Coast, where export terminals such as Corpus Christi and Freeport operate. This infrastructure has expanded the country’s LNG processing and export capacity, helping establish the United States as a major player in the global market.
Industrial growth has also increased the region’s water requirements. In response, several alternatives have been explored over the years to expand and diversify supply, including water reuse, groundwater extraction, desalination and other supply options.
The challenge is that identifying a need is not the same as having a solution available when it is required. Infrastructure projects take time to plan, finance, build and bring online, while weather conditions and water demand can change much faster.
The situation prompted Corpus Christi to prepare for a potential water emergency and adopt measures to reduce consumption and protect its reserves. The key issue was not just how low reservoir levels fell, but how quickly a region’s safety margin can shrink when prolonged drought, rising demand and limited water sources coincide.
Although rainfall helped reduce the deficit, it did not eliminate the system’s vulnerability. Corpus Christi continues to implement water restrictions and has adopted additional conservation measures to protect supplies in its main reservoirs. At the same time, the city is pursuing alternatives to expand and diversify its water supply.
A city may replenish its reserves after a period of rainfall, but it cannot assume the next climate cycle will follow the same pattern. Nor can it wait until a water source reaches critical levels to begin developing infrastructure that may take years to plan, finance, build and bring into operation.
The Situation in Mexico
This is particularly relevant for Mexico, where several regions are seeking to capitalize on new industrial investment.
New facilities, the expansion of existing operations, and the development of industrial parks and corridors all increase demand for energy, infrastructure, talent, logistics and public services.
The climate outlook also adds to the need for preparation. Specialists at the UNAM Institute of Atmospheric Sciences and Climate Change have warned that El Niño could be particularly severe in 2027, increasing the risk of drought in several parts of Mexico. This makes it more important to anticipate potential supply constraints and strengthen water infrastructure.
When assessing whether a region can sustain long-term growth, current water availability is not enough. We also need to understand whether supply systems can meet future demand, how they would respond to prolonged drought and what alternatives would be available if conditions change.
Not every region or public institution has the budget to develop large-scale water infrastructure independently. However, funding constraints do not have to prevent the development of additional supply capacity.
Public-private partnerships and specialized water operators can help accelerate projects that might otherwise take longer to implement.
The Role of Water-as-a-Service
This is where models such as water-as-a-service (WaaS) can play a role. These arrangements allow public institutions, private companies and specialized operators to share responsibilities and resources, helping develop water capacity without relying on a single party to finance the entire solution.
Under this model, the company or institution requiring water does not necessarily have to finance, build and operate all the infrastructure itself. Instead, responsibilities and risks can be distributed among the parties, while the user contracts for water supply as a service.
Securing water for incoming industries also requires consideration of the cities and communities that already depend on the same sources. A new industrial facility does not operate in isolation: its water demand adds to existing consumption. Industrial expansion must therefore be supported by planning that increases supply capacity without compromising access for the people and businesses already operating in the region.
This requires assessing potential scenarios in advance. What would happen to an industrial region if rainfall remained below average for months, if an existing water source became less reliable, or if demand continued to rise at the same time?
Corpus Christi shows that a water crisis does not necessarily begin when a city runs out of water. It can begin much earlier, when reserves decline, the margin for managing supply disruptions narrows and a region becomes increasingly dependent on favorable weather to replenish its water sources.
If the investments being made today are to remain competitive over the next 10, 20 or 30 years, water planning must keep pace with industrial growth.
